Not safe in office

SuicideGirl Belle and Sebastian Music Video - NSFW from SuicideGirls on Vimeo.


My friend, she wants
To be a Suicide Girl
I'll take her picture
For the whole wide world
I've known her for a long time
You could say that I'm a fan
But I always thought that
I would be her man

My friend, she wants
To be the girl of suicide
She wants a number
For her radical side
I know that she is special
I can see what she has got
But what I have loved and guarded close,
She will take, and to the world exposed,
She gives it all away.

My friend
She sometimes gets anxiety and stress
She got a manual
From the NHS
She proclaims a week of sadness!
Please abstain from telling jokes!
The world will see her poet emerge
A butterfly to empathy
I know that I can do it
I'm in to light, I'm in to shade
But let's face the facts
We ain't going back
When she takes off her clothes
We'll never be the same again!

聖誕半裸派對

Do you hear what i hear

this is a classic Xmas song.

the rhythm is very nice.

the lyric is very classic....al shit.

one point i very dislike about religion is, they always demand a superpower,  a king, a super hero to save to world. then, the rest can sit beside, waiting for being saved and may be having sex at the mean while.

thus, they always under-estimate the power of ourself.

and that is what i think why the religion can not save the world, in fact, they are trying to save it for 2000 years!!! and fail!

Jump!

起床 Get Up!

由鬧鐘響起的一刻，爭扎便開始。

At the moment the alarm shouting, a struggle has began, ironically, the very first idea is NOT wake up. when we start to flight against this idea, our hand was already betrayed us by pressing the snooze button. although our hand saved us from this struggling decision, plenty of decisions just started. Is it the Welcome to the beginning of a day!? 

The first thing to be decided, well, you can argue that it is not first, but it is hard to say we were really deciding to press the snooze button on our own, anyway, the 1st is when is the best time to wake up, well, it means, when is the last time I should wake up before too late. Can I sleep 5 more mins? 10? Oh, may be 15. 5 min is never been so precious and the most interesting thing is, we can think really fast! Within the 5 min between pressed the snooze button to the next alarm, i already figuring at least 3 possibilities. the 1st is, may be i can skip the morning shower, by the way, the weather is not so cold, i did not sweat last night, that's save 15mins. 2nd, may be i can skip the breakfast, thus save another 10 mins. 3rd, um,,, may be i don't shave this morning. my beard is not so long...and more and more...

then the alarm ring again. um... no matter how i change the alarm sound. it will turn out to be the most annoying sound ever. i better no use my favorite music as a morning clock alarm....

After pressed the snooze for 2nd times, delay seem to be far from satisfactory. and start to think about ABSENT. may be the class is not important, i can catch up by myself in half hour. it will be save. may be no one will care weather i am there or not. Really? will my classmate miss me? will my professor care? i was quite active and involved in the class. will my absent disappointed my professor? 

the sound of the 3rd alarm strike into my mind. and now, i barely open my heavy eye lips, i just wish i am sick and have a good reason to be absent! when the number on the clock is clear....

What!!!! how come it is faster by 10 more mins??? it should be the 3rd alarm, not 4th! are you fucking me??? hah??

Ok, better take a hot shower and shave my beard, have a full breakfast, i feel quite hungry in this morning and eventually, it is the breakfast is breaking slow and i was late in the class.....

how to know "right" is right!

Inspired by 怎知對是對

so far, human can only deal with logic in mathematics to prove somethings right or wrong in a consistence structure/system. or you can call it "proof is contained". (in fact, the Gödel's incompleteness theorems stated that there are somethings cannot be proved even in mathematics!)

For things not within the kingdom of science, there is nothing right or wrong. only popular or not, eyes catching or not. an example is the Marx's communism, he said that it is "logical", "scientific", but when you look at the arguments, it is simply a set of opinions without or cannot be proved. the so called "social science", is nothing science at all, or, a weak science. why? because they use hundred and thousand of assumptions. Comparing with social science with mathematics, physics or some what strong science, we can see that those are only based on few assumptions. take the Euclid's Elements as an example, the book 1 only has 23 definitions and 5 postulate, and by these, the whole set of 2nd school geometry was built.

in my opinion, we only have few things can be said "right" or "wrong", coz most others are not subject to prove! so, if we want to know "how to know right is right", we have to ask it within an area that "right" or "wrong" is well-defined.

One idea for promoting sport and excerise.

Use those health care commercials, but when the product show up, change it to say,

'Don't want that happen on you, excerise now!'

'according to servey, it is due to lack of exercise."

' your skin can back 10 years after you have regular exercise."

' Stressful? Feel full but hungry? sport can save you!'

an idea for genetic food

plants can be feed by sea water.

it also help to fight for fresh water saving.

Getting Wiser

depends on Laws (privacy selling)

selling personal data to 3rd party by bank,  telecommunication companies is a hot issue in hong kong.

yes, people can rely on setting up a law, to restrict and open the use of personal data (PD).

i think it is stupid and silly.

because the responsibility is on ourself, on the people, not the government.

1, people have to open a bank account, a cell phone to survive in society. our PD has to hand out to them. the contact designed by the companies must contain the right of using those PD. even those we set a law to constraint the design, like bigger letter, color letter. Can we say a NO?? can we not sign the contract?

2, the PD has value, because company can make profit on it, like cold call, or other mean. Anyway, they can provide some products and make profit. therefore, some people do buy the product from cold call. the hold market can survive, cannot only has those companies, but no customer! and also, some people has to work on this, to make the phone call. people can live from it!

in my opinion, people has to say NO to EVERY cold call. if no one buy the product, the product cannot make profit, the PD will be useless.

However, if follow this thinking, this mean, the company can really sell those data to make profit, some people really buying the product!

all in all, i mean it is in fact not a problem, it is just a economic issue. and the chaos from selling PD is just a adaption period of a new business. people has to learn how to say no, stand up to themselves.

one very interesting thing is, the Octopus company earned 40 million HKD from selling PD, why no body sue it and ask for compensation? we can ask for the legislator near you! why no body do that? if it is really a matter, why no people move?

That is the reason why i like 'kick-ass' !

*********************
telecommunication should show which company is calling from. in fact, this is no new technology, but just no one use. why we have to remember a number, instead of the company name to make a phone call?

When lost

of course we should pursuit our dream. i think we are now dealing with a goal, a short term goal of a long life. The trouble was happened because you cannot reach your goal, not your dream, right?

A GOAL should be designed after we understood ourself, our strength, our value, and our position. 

while a dream can be anything make me happy.

i believe you are now not satisfy, not feeling fulfilled from your post. and you want to be a person-in-charge for companies loan. i suggest you should answer those questions in that article, before you can persuade others, and also give yourself a solid foundation for doing that. 

1, 我有哪些長處？ What Are My Strengths?

2, 我的作事方法為何？ How Do I Perform? 

3, 我的價值觀是什麼？ What Are My Values?  

4, 我歸屬於何處？Where Do I Belong?  

5, 我應該貢獻什麼？ What Should I Contribute?  

when you can answer those questions and present them to your boss in this way:

是的，我願意做這件事，但我會用這種方式來做這件事；此事應該如此架構；與其他伙伴的關係應該是這樣；你可以預期我達成這些成果，預估的時間是如何如何，因為我就是這樣的人。


Yes, I will do that. But this is the way I should be doing it. This is the way it should be structured. This is the way the relationships should be. These are the kind of results you should expect from me, and in this time frame, because this is who I am.

Then, i think everyone will give you a chance. =)

研究計画

I am going to take part in Nuclear Physics for investigate a method of proton spin polarization under high temperature and low magnetic field strength and others related research, such as the scattering of heavy isotopes on polarized proton target. The project is branch of Dynamic nuclear polarization, which is transferring spin polarization from electrons to nuclei (protons) by cross polarization.

The polarization of proton can be used in width range of applications. It is called Hyper-polarization, because the polarization beyond thermal equilibrium or the Boltzmann Distribution.  This can be applied to enhance the efficiency of Nuclear Magnetic Resonance (NMR) and improve the resolution and application range of Magnetic Resonance Imagining (MRI), which has greatly useful from medical, chemistry to quantum computing.

One important application of the polarized proton is investigate the nuclear structure. For example, polarization study of unstable isotopes by scattering it with highly polarized proton target.  Since the current technique is difficult and expensive to achieve low temperature (sub-Kevin degrees) and high magnetic field (several Teslas). The thermal movement of atoms will destroy the polarized electron spin by collision with other atoms. Therefore, lower temperature can get better polarization efficiency. According to the Curie's law, the magnetization, or the electron spin polarization, is proportional to the external magnetic field and inversely proportional to temperature. Therefore, low temperature and high magnetic field is essential for spin polarization. The study is hard to be deployed. 

Currently, Professor Tomohiro Uesaka's group had achieved the polarization at temperature 100 K and magnetic field strength 0.1 T. The resultant proton polarization rate is 20%. The group use doped crystal of naphthalene (C₁₀H₈) as the polarization target, because of the π-electrons play an important role in the “Inter-system crossing” among different energy levels. Therefore, the group use Laser as a mean for exciting the electrons and undergo energy level transition. The electrons will be distributed on a triplet state m = +1, 0, -1 with different population and then polarized. By cross polarization, the group is able to polarize the proton spin.

The main objectives for my doctoral research is to investigate and improve the condition for maximize the polarization rate. The spin of proton also contributes magnetic field. The polarized proton spin gives a much stronger magnetic field. Professor T. Uesaka's group uses total magnetization (Polarization ratio times Total volume of the crystal) per power of laser as a measurement of the polarization efficiency. The current efficiency is around 7 [% mm³ / mW]. At this point, if the efficiency keeps unchanged, higher laser power will give out higher polarization ratio. The bigger challenge will be a higher ration, bigger crystal volume and lower laser power. Another improvement is increasing the working temperature or lowering the magnetic field while keeping the polarization ratio the same. This is possible in theory, because the population of the triplet state is independent of temperature and magnetic field.

By studying the spin polarization, several possibilities will be opened, such as applying the spin dynamic into quantum computing or study unstable heavy nuclei, like O-22, (which has 16 neutrons), C-22; or He-8. The unstable nuclei has un-ordinary spin-orbit coupling that changed the fine structure in nuclear system. This is an important discovery in modern physic that explained why some isotopes are more stable than others. The fine structure in nuclear system is similar to atomic system. The strong nuclear force in the nuclear shell model plays a similar role as the electromagnetic force in the electron shell model. The shell model gives protons and neutrons orbiting in shells. Thus, spin-orbit coupling will change the energy level. In 1963, Wigner, Mayer and Jensen shared a Nobel Prize for it. The change of fine structure of an unstable nuclei can be largely different form a stable one. With the help of a strong magnetic field from a strongly polarized crystal, we can study of the spin-orbit coupling. Therefore, proton spin polarization is a foundation for future research and study.

I have a vision after I finished the course. I become both skillful in experimental technique and mastering theories. I believe this is basic requirement for research career. Besides knowledge, I wish through out studying oversea, I could able to learn how to work with others, who are from different countries and cultures. Also, I can live by myself and look after others. These are very crucial for doing research and personal enhancement as well. At last, I want to become a mature and professional scientist. That is my dream and also my parent's.

Field of Study (as a reminder )

My major interest in physics is the electromagnetic theory, especially optics, from geometry optics, wave optics to laser. I was extensively trained with electromagnetism courses. I am able to solve the Maxwell’s equations analytically in specific geometries and numerically in most geometry. My first research project on my bachelor course is about the structural color in nature, like the scales of butterflies, bees and seashells. After employed modern laboratory techniques, such as SEM (scanning electronic microscope), TEM (tunneling electronic microscope), and our group revealed that the color of butterflies is based on a very simple principle – multiple thin films reflection or interference. The color is not form pigment as most people though, it is completely form the microstructures of chintin, which is a common material in nature. By changing the thickness or geometry of the structure, we are able to change the color reflected.

The second research project is about fabrication of the structural color or the photonic crystal, by using holographic lithography. Holographic lithography records the intensity pattern from laser beams interference and forms structures on a photoresis. The size of the interference pattern is determined by the wavelength of the laser used. A UV laser is able to produce 200 to 800 nm sub-micro structures. The structures at this scale can push the optical respond range to visible range. This method is also able to produce a large sample (5 X 5 mm²) by expanded the laser beams. A large sample makes optical spectrum measurements possible.

The objective of the project is fabrication of a sub-mirco-sized gold particles array and study of the surface plasmon resonance (SPR) when EM wave incidents on it. The surface plasmon is a quantized state of the vibration of surface electrons; thus, only metallic or conductive structures have such effect. For a single gold particle, the frequency of the quantized state is given by the size and geometry. A simple imagine is the gold particle was polarized and like a giant dipole oscillating with the external field. The effect of single dipole is weak and impossible for measurement. The array of dipoles will give strong and extraordinary effect when they are in resonance. One example is the extinction, which is defined as log(1/T), there T is transmission. The high extinction means low transmission. Our group found that the extinction peak was blue shifted from elliptical spheroid to good sphere. The result is same as numerical simulation.

My master research project follows the same technique. But instead of fabricate gold particles array, I were going to fabricate spiral structures. The fabrication required interference of 1 circularly polarized beam and 6 linearly polarized beams with very fine optical alignment. Therefore, the project took a lot of time for fine-tuning and optimization of the laser beams configurations, such as incident angles, polarization, and intensity. We also used computer simulation not only in the design stage, but also in the improvement stage. We are able to find out the factors that creates defect in our sample. Our group had also designed and set-up the measurement equipment and technique for measure the full state of light polarization with limited equipments. The special effect for a polarized light pass through a chiral slab is the wavelength dependence of the change of polarization angle. The polarization angle of blue light will be rotated larger than that of red light. The result can be explained by classical EM theory with the introduction of chirality factor in the characteristic equations that connect the electric displacement field and magnetic induction with the electric field and magnetic field.

I am also interested in the atomic structure. Therefore, I took 4 related experiments on a modern laboratory course. They are Millikan oil drop, Zeeman Effect, Optical Pumping and ESR (electron spin resonance). Those experiments not only enhanced my understanding, but also polished my experimental skill. Moreover, those experiments bring me into the real world that is a lot different in the theory. There are a lot unexpected and practice issues appear when performing an experiment. That is the fun and interesting aspect of doing experiment.

1 bottle or 3 bottles? (II)

Extend reading : 1 bottle or 3 bottles

In that article, i used the expectation of "Utility" replacing the expectation of "bottle". 

somethings wrong with this. isn't it?

because the expectation is still there. the reality only approach to the expectation when there are many many trials.

but wait, Are we really using the expectation of "Utility", or just compare the utility for different results?

if we have equal utility for both 1-sure-bottle and 1-unsure-bottle. thus, 1 side has total utility is 1 and other side is 3. in this case, since we treat both kind of bottle are the same, so, we, of course, choose to bet the 3-bottles.

So, the question is, How the uncertainly devalue the utility?

well, it may different from different people. and by only compare the total utility, we can know, if the utility for a 1-unsure-bottle is lower then 1/3, then people will not like to take the gambling.

but what is different now? i think what i say is still running around the question!

think about what is utility? it means how would you like the trade or compare different things. so, we still using "utility" replaces "bottle"!!!

we just assign a value to each bottle and then say, "hey, i like this more than that, is because the assigned value are different!" which is simple to say, "i made up a reason & regardless of the chance."

**********************************

in the game holder view point.

he has to buy many equal bottles, which has value , say, 1$. 

the cost of 1 sure-bottle is 1$, and 3-unsure-bottle is 3$, with 1/2 chance. the expectation of cost is 1.5$.

when he hold the game. the value of unsure-bottle devalue, or, relatively the sure-bottle up-value to 1.5$ for loss free. 

Interview

Today, i encounter a funny question when interview.

interviewer, " What do you expect or seek from the job? money? working experience? future development? "

me, " Can i have them all? "

interviewer, " Yes, sure, but you have to rank them, which one is on the top of the list? "

me, " if i have to rank it, is it mean your company cannot provide all of them? "

interviewer, " Yes, we can, but we have to look your characteristic and preference, so, we can give you the most suitable training and development plan. "

me, " Ok, i prefer all of them. :) Does your company have a plan for people looking for all of them? Does your company have to divide people like this? money, working experiment and future development is a constant sum. One more, the others must be less?  "

interviewer, " ................... "

i guess, the interviewer fall in a trap set by herself. her question is implying only one of them, this is the answer she have to find out. and She insists to it and believe people can be classified like this.

At last, she only can say "yes", when i asked a negative question, she fail to respond. In Asia, people fear to disagree. disagree = disrespect are equal in most people mind. But it is not true.

job title

As Companies like to make fancy title for very normal job, as if this can make the job more fun or professional. here some suggestions:

for those who graduated from school of engineering:

• Insurance engineer 保險工程師 (who is a insurance salesman)
• Tele-Sale engineer 電銷工程師(who is a tele-salesman)
• Education engineer 教育工程師(who is a teacher or teaching assistance) 
• Audit engineer 審計工程師 ( who is working in audit)
• Hygiene engineer 衛生工程師( who may be a toilet cleaner with a degree in engineering )
• Transportation engineer 運輸工程師( who is driver for transportation, like bus driver, but, with a degree in engineering )
• Garment engineer ( who is working in garment industry )

As long as the working is holding a degree in engineer, he/she more or less will solve problem in engineering way, so, added a title with engineer should be proper and sound professional!

For those who graduated from humanities :

• Insurance humanist (who is a insurance salesman)
• Tele-Sale humanist  (who is a tele-salesman)
• Education humanist  (who is a teacher or teaching assistance) 
• Audit humanist  ( who is working in audit)

• Hygiene chemist ( who may be a toilet cleaner with a degree in engineering )
• Transportation chemist  ( who is driver for transportation, like bus driver, but, with a degree in engineering )
• Garment chemist ( who is working in garment industry )

what is your Job nature and your degree ?

For me now:

Housekeeping Physicist  :P

Incentives mechanics

Can people be treated as a mechanics?

Animals can. 

when we have 2 choices, we will pick up the most valuable one, or the better one, according to our utility function. we tend to spend less and get more. say, the price of a can of coke is cheaper then a bottle of milk, and the satisfaction (or the utility ) is the same for me,  i will take the coke, coz i can spend less but get higher satisfaction. when the coke is $1 and the milk is $2, and and now, i prefer milk more, then i may take the milk. In such a case, when a problem exist a optimum solution via analysis, i will like the call : Un-choos-able Choice. quot from Shakespeare: be or not to be, it is not a question. 

an indifferent choice raised when the 2 choices are same cost and the satisfactions also the same. Then, i will call this is a Indifferent Choice.

Like everything, there is a margin for uncertainty. for example, a red dress is $100, a green dress is $101. can we really "feel the different"? are we so sensitive for a small different. how many people can really tell the different between following number" 

1/2, 2/3, 3/4, 4/5, 5/6, 2/5, 3/5...

unless we changed to digital number.

0.50, 0.67, 0.75, 0.80, 0.83, 0.40, 0.60

OK, what am i talking about this? 

the reason is, we act according to different situation, different feed-back, different input. For those Un-choos-able Choice, there is no freedom at all, (unless we are stupid ).

Even for those Indifferent choice, we can increase the incentive, then we can make it be a Un-choos-able choice. 

We all be driving by the incentive. 

unless the assumption is not correct : we do not tend to spend less and get more. 

is it the beginning of moral? How about sacrifice?

We are not different at all.

In Asia, people can see the different from different country, we can tell, Chinese, Japanese, Koren, Taiwanese, are different. and even people can tell, Tokyo'er, Kyoto'er are different, Hong Kong'er and Shanghai'er are different.

In Europe, people can do a similar things. they can distinguish Germany, British, Greek.

Similar in Middle East.

People know their neighborhood very well, and able to classify. one result is, a boundary is built. freedom lost, conflict raised.

From Westerners eyes, Asian are Asian, we are almost the same. If we are the same, why we kill each other? why we can not understand each other? it is just because "countries" ?

If we have a bigger picture, Human are similar, we share 99.9999999% of same DNA! our structure or ingredient are the same! May be less the different between Coke and Pepsi !!

If we have even a bigger picture, all living creature are similar! we have to live in this earth. why not cooperate?? making things better to each other, Win-win situation.

In order to have bigger picture, we have to learn and discover. Move now!

曾余辯 by ATV

1 bottle or 3 bottles ?

there is a game:

you can get 1 free bottle. or you bet this bottle, for a chance of 1/2 for 3 bottles or 0 bottle.

what will you do?

In logic, you should bet the bottle, coz the expectation is 1.5 bottle, while the other one is 1 bottle only.

However, don't for get what is "expectation", which is the mean gain from large number of trials.

if you only get one chance,  what will you do?

may be we can introduce a utility for the bottle. say, you need a bottle so much. like a medicine, you need it for your life, so, the question will become weather you have a bottle for sure or chance for more or zero bottle. Thus, 3 bottles for you may be not so useful, attractive or necessary. therefore, if people have no bottle on their hands, they will prefer to have the guarantee bottle.

If people already has few bottle on their hands, thus, the guarantee bottle is not so attractive. so, why not gambling?

The utility function can be like this. it depends on the result, on how many bottles people already have.

For no bottle people, their utility function may be 1 for  the guarantee bottle and also 1 for the 3-unsure-bottles. means both of them is equal attractive. thus, the expectation of utility is 1 to 1/2, ok, pick the guarantee one.

For had some bottles people, the 1 bottle may be only 1 for them, but 3 for the 3 bottles, which means, the 3 bottles is more attractive. the expected utility is 1 to 3/2. Gambling.

How about the 3 bottles changed to 100 bottles?

the utility changed. and you can see, different people has different utility.

*******************
Let's talk about utility.

although utility is different from different people, it can be compare within same people.

what does it mean i like coke more than milk? if my utility function for coke is 3, milk is 1. thus. i like to trade 1 coke for 3 milk in order i got satisfy.

wait! how about i hate milk? at this case, the utility of milk will be negative, say -1. Thus, no matter how, i will not trade a coke for milk!

next time, if you want to compare somethings logically, try to think how many of these can trade for that.
*******************

back to the game.

in order people will gambling even they got no bottle, the utility must be 1 for the 1-bottle and at least 2 for the 3-bottles. This means, you like to use 2 guarantee-bottles for 3 unsure-bottles. the uncertainty lower the attractive to 2/3 for each unsure-bottle.

How about in 1-sure-bottle vs 100-unsure-bottles with 1/2 chance?

the utility for choosing 100-unsure-bottles is still at least >2 . and the attractive for each unsure-bottle becomes at least 1/50 due to the uncertainly. we can see, this de-valuation is so huge. many people will agree the attractive of a unsure-bottle should be more than 1/50. say, 1/2. Thus, from the utility, we can see the total utility for 100-unsure-bottles is 50, very easy to larger than 2. Therefore, people may even choose to take the chance even though they did not have any bottle.

******************
Other issue, in the game holder view point.

people can buy a coke or buy a chance to win 3 coke with same price.

............um.... i have to think about this......

How about apply this "trading" for politics? to solve conflict? like terrorism?
How much they can trade for the "Muslim" to stable life?

An observation on a Turkish class.

The class room is no fans. Like a tutorial, not using powerpoint. Students can speak and talk to the professor like they are chatting. Students are active, responsive. No lectture notice, student write their own. So, it quite depends on th talent of each student. Ebru does not take note, while most studnt are taking. Is she good? Or just lazy? But it seem that her way of study is by listening, rather than note taking. My style as well.

The classroom is quite hot.

The writing of the professor is quite un-organized. Some where there, some where here. But he write down the point, and develop it. Note taking students may be a problem. Words are small on the white board.

No clock.

The professor is quite talkable. He come back to previous idea. Alhough the equiment is not as good as hk, student are btter. May be also the subject are different. Economic and phyics. By the way, why economic cannot be teach in a mathematical way? Lets the formula and logic tell the story.

In physics class, a lot of mathematics. Well, no. Only othere subject less mathematic.

His writing is real ugly.he needs a copy-book. =)

He use questions, to raise up curiosity to students, and tell them the answer.

E = m c square

There are 3 mass definitions:


inertial mass, which respond with acceleration when force applied.
gravitational mass, which produced the among of force by gravity.
relativistic mass, which is a fictional mass created by Einstein.

Many people say, when something get heated, than energy increased, thus the mass increased and it becomes heavier. According to Einstein's equation E = m c^2. Completely incorrect. They totally mix all three definitions of mass all together, and has a mis-understanding of heavy and "hard to be moved".

This equation tells us that mass and energy are equal, mass can change to energy and vice versa.

therefore, as long as the kinetic energy still "functioning", as shown that the heated thing still hot. thus the energy did not covered to mass yet.

In nuclear reaction:

He-4 + N-14 -> O-17 + H-1

the mass of He-4 + N-14 = 18.00567 unit
the mass of O-17 + H-1 = 18.00696 unit


The gain of mass from energy. the energy is needed because, the 2 nuclei has great electromagnetic force between 2 cluster of protons. After the combination, the kinetic energy will be converted to mass, as a blinding energy.


To fully understand this equal, we have to distinguish 2 similar but different concepts - equivalent and exchange. Both concepts are simple. They mean the same or equal value. Like 1 US dollar can exchange/equivalent for 7.8 HK dollars. However they are little bit different.


First of all, may be we should return to a more fundamental equation:

E = K + mc^2

Where K is the kinetic energy, m is the rest mass of the object.

This equation means the total energy contains 2 parts. 1st is the kinetic part (you can say, the energy because of motion), 2nd is the mass part (you can say, the still one). Now, you may argue why "Total" energy only has these 2 things, how about sound energy? light energy? chemical energy? The answer is, if you are smart enough, the kinetic part contained all this kind of energy and the truly amazing thing is, mass can be energy as well!!

Let me explain a little bit about the kinetic energy as well. As we known, sound energy is same as vibrating energy of air molecules. For light, it is a non-stop particle (in particle sense), and according to special relativity, it only has kinetic energy but no mass. And for chemical energy, which is in fact electromagnetic energy, which is light energy. How about Potential energy?? Good question! as you can see, for gravitational potential energy, this energy is stored in the field, not on the object.

Thus, E = m c^2 is just a simplified form when there is no kinetic energy.

According to special relativity, it is more harder to accelerate a body for a higher speed. however, it does not implies the body was heavier! More technically, it is because the momentum changes lesser due to non-linear space-time.

remember, there is no relativistic mass. this is a great misleading simplification of Einstein. he likes to simplify equation a lot and he made this:

K + m c ^2 = M c^2

where m is the mass (or rest mass), and M is the so called "relativistic mass".

He introduced this misleading concept because it is much more easy to tell the public why it is harder and harder to reach the light speed.

Correct interpolation for E = m c^2 is exchange, or replace, but not equal. This means, energy or mass can either exist, but not both. Just like you pay 2 dollars for an apple, you will not get back the 2 dollars. another example is light, photon. Photon has energy in electromagnetic form. Does it mean photon has mass? NO, photon has no mass according to special relativity, otherwise, it cannot move in speed of light. Therefore, we can see, the kinetic energy has no contribution to mass.

Best of worst VS Worst of best

i like to think i am smarter than others, mostly. i am not only can think, generate new ideas, but also make them real.

But the truth is, i am smart just because others are not so good.

take chess as an example.

i beat many people, does it mean i am smarter?

may be, but the more reasonable reason is, i play more.

when practice chess with computer, i knew there are many many tricks and skill i dun know. and my national ranking (if there is any) is below mean of the world chess players.

Thus, the reason that i always win is just because my opponents are not chess player or not played more than i do.

I suddenly recognized that it is so danger for i did not notices that before.

Game VS Life

many people say life is a game.

i hold a different point of view.

you can quite the game, give up anytime; you cannot give up your life.

you can play again; you don't have 2nd life.

game has rules; life don't have any rule.

Life can be a game, but game is not a life.

no need a lot of different.

Anyway, life is a game can give us some relief when shit happens.

Energy of Life

The energy of life is the decision of controlling his life. To practice his own will.

My life is my story, i can do what i want. I should be the writer of my story. I can take the responsibility. I can suffer the pain of my action & enjoy the joy of my success.

I love myself, to make myself to be better, every minutes, everyday. I have good things and also bad things. No matter good or bad, they define me. The worst life is acting and fitting other requests, doing what others want me to do, and then, get lost.

That is so called the enlightenment. The wake up of the soul. The realize and practice himself.

Without this, we cannot love. Because we are not free. We are still living for others. Many people are in "love", in fact, they are escaping from loneliness, seeking for security provided by others. They are together because of fear. The good tester is jealous. Can they allow the others has a close friends of opposite gender? Coz, jealous only exist when there is no love, no true trust.

What is love? Love is making things better. Love is originate from oneself. The primary object for love is myself, to realize that he can beloved by himself. And this love can be extended to others. After he love himself, he has confident, he can trust, then he can be independent.

He can control his life.

To control your life, is the will to control your life.

what am i blogging for?

first, it should be something i want to express to public.

2nd, it should be something truly from my mind, something originate from me.

otherwise, why i post others opinions? why i talk stories without souls?

blogger is not a reporter, should be different, right?

Blogger should be a writer, to create, to construct, to dig out questions, to answer questions.

The problem is, how do i know those ideas in my mind are from me?

we process a lot information each day, we remember, we use it, we put them on to other things.

But even we can able to use what we learned, they are not originate from myself.

for an analogy, we learn then we use, like we breakup the food into tiny elements, and then re-construct, use them in our boy. but those thing is already exist, not us.

well, we can get some relief to say that the combination is the thing we own. like buildings, every buildings use similar construction elements, like bricks, irons, steels, woods, concretes, glasses, etc..

Frankenstein is a combination of human body's parts, can it be a creation?

May be, but it is hard to say a truly creation, may be i called it creative level 1 - new combinations of old stuff.

for creative level 2, i expect to see some new dimension, an improvement. like, from ape to human. like new building material, for example, solar power panel, steel-concrete, or concrete-steel. colorless-steel, or bio-painting.

well, may be need no be so hard.

only blog something that "i think" it had soul. "i think" people seldom notices, or unseen.

Fastest Speed? (II)

The last entry about Fastest Speed? has new thought.

for the reason why the speed of light is fastest. The reason can be simple. no need any equations.

The reason is, the speed of light is the same for all constant velocity observer. and we use light as a measurement tool.

For simplicity, we can imagine a "magic bullet" that travel at same speed no mater who measure it.

we can use this magic bullet to build a clock. the clock is made by a gun and a target, a standard time can be defined as when the bullet hit the target.

Lets say, John is moving at speed of this bullet compare with Mary. and the clock is on John's hand. we can freely to say John is not moving but Mary, or Mary is not moving but John. 2 arguments are same.

In John, the clock run normally. since we can say john is not moving.

But in Mary, John is moving at the speed of the bullet. and the bullet also moving at the speed of bullet. therefore, the bullet never reach the target. Thus, time stopped.

people may ask this clock is not a good clock. we can build another clock by different principle and give out different result. But remember physical law is same no matter who or how to check it.

Thus, if John is moving in speed of light. The time for he in others people is undefined. as the time begin undefined, the space also. Thus, John is living in crazy time and crazy space (but existing ?) in Mary's eye. Therefore, normal thing cannot move at speed of light.

**************

For time begin undefined, the space also.

space, length, we can simple use a ruler to measure or define it. However, it is not always.

first, we have to make sure the 2 ends are not moving compare with each other. if one end is moving, any length measurement is fail.

so, How do we make sure the 2 ends are not moving? we are only 1 human, may be we can make sure out hands are not moving. but how about length is many times longer? ask someone to help? How?

we can use light. because its speed depends on nothing.

John can send a light to Mary, who carry a mirror. They are on the 2 ends. John can simple measure the time for the light return back and forth. if the first time is same as second time, we can say the 2 ends are not moving. ( strictly speaking, John only knew at that 2 time intervals, the ends did not move; the ends can move but at the time the light hit the mirror, Mary is on the same point. )

if the clock of John is broken, he never able to define a length.

by the way, undefined does not mean it is not exist.

**************

A: Why the speed of light depends on nothing?

Q: i mean, it does not depend on observer. in fact, it real depends on something, the permitivity and permeability.

Passing through

kids are able to different right and wrong. world is simple. and it should be simple (i believe)

after educated, things becomes right and wrong. blur, not clear.

after deep understanding, things become right and wrong again.

**************

learning new things, we have so called beginner's luck.

people can see through a problem by simple thought.

while educated people make thing complicated and believe thing should be complicated.

Than, a real Master can give a simple solution.

***************

when broken with lover, people feel sad.

some may seek happiness by ignoring the sadness deep inside.

some may face the sadness.

only few who faced the sadness can get pass.

But only the few can know what is real happiness.

***************

it is bright before a dark tunnel.

but only passed the tunnel, we can go to the other side of brightness.

and by only so, life can move on rather than stay put.

anxiety

have you ever worry about somethings, that you do not feel any pressure at all but just anxiety?

Like release of examination result. you know all you can do is done and just wait for the result. If it goes bad, you only can admit it.

Like date a hot girl. you are not sure completely, but just wait. Somehow, you may think she will show up and start to imagine how the data is going on, what will be told on the data, what kind of dress she may wear. When you imagine more, yo realized that it may not be true and even the girl does not show, you feel anxiety.

For something, you are so not sure the result. of course you really want the good happened. And you have a lot of planning after this. But you just afraid the imagine. you afraid it is not real, it will not come true. How come such a good thing will be happened on yourself! you afraid to dream about it, you even forbidden a single moment about this thing pop out in your head. But occasionally, you realized the date of the result is closing, you will think of it.

Sometime, you start to think it must be bad, it will be fail. The good thing will not be happened on yourself. And you feel some release, not so worry about it so much. However, if it is really bad, you even do not have enough imagination to think about what to do afterward. Because all you want is change. your world did not changed and your world should be ended.

Hope is a double blaze. good-side, anxiety. bad-side, end of the world.

Patient, will it help?

Let's cell phone replace writing pad

there are cordless keyboard, mouse, mic, speaker, and many other devices.

How about cell phone?

Now, we have used cell phone for internet, act like a bridge.

What if my cell phone has touch screen and support hand-writing?

using the connection to PC and the touch screen. May be we can replaced hand-writing pad.

Water quality

Recently watched a commercial, It take about the quality of water is graded by number, 10 is the best, 9 and 8 is poor and so on.

It is quite misleading. When taking about quality, it means that there is no best quality, only worse. The scale is from bottom to top. Moreover, it means a progress to get a better quality.

That should not be used on Water. Better use Purity.

Water is a pure and clear concept. H2O, no more, no less. If i say i need some water, of course i only mean i want H2O. (if you don't have, you can give mineral water or tape water.) There is 1 and only 1 quality of water.

Thus, anythings else added on water reduced the purity, not quality. ( i should admit that these 2 words are very close and easy mix up.)

Purity is using a different scale, from top to bottom.

Take another example, Diamond.

Since Diamond is a pure concept, Carbon with the unique arranged lattice structure. Thus, the color of diamond is grade from D, E, F, G....., From top to Bottom. There is a perfect (best) "quality".

**************

the commercial pissed me off because it is telling and convince me that, water should not be just H2O. We have to buy for it. Shit, Water is an essential element and we have the right to expect it is not a luxury.

Thermodynamic Humor

Zeroth Law: Thermodynamic Equilibrium

A system in thermodynamic equilibrium is by definition its most probable

state; all processes have essentially gone to completion and its macroscopic

variables are unchanging. Also, if two systems are in thermodynamic

equilibrium with a third they are in thermodynamic equilibrium with each other.

First Law: Conservation of Energy

The increase in energy of a closed system is equal to the energy added in the

form of heat minus the work done by the system on its surroundings:

ΔU = ΔQ - ΔW

Second Law: Entropy Always Increases

The entropy of an isolated system will only increase with time. Generally

ΔS ≥ 0

The entropy will approach a maximum value as the system evolves in time.

Third Law: Absolute Zero

As a system’s temperature approaches absolute zero all processes cease, and

the system entropy approaches its minimum value.

*********************************

Zeroth Law

“You must play the game.”

First Law

“You can’t win the game.”

Second Law

“You can’t even lie the game.”

Third Law

“You can’t get out of the game.”

Highest temperature?

Last time, we explained the existence of the highest speed.

a very direct consequence may be the highest temperature.

According to the kinetic theory, the temperature of a gas depends entirely on the speed of its particles.

number of mole * a constant * Temperature = one and half * mass * square of speed

Thus, the highest speed set a upper bound of temperature.

when we put the number in it, the highest temperature for 1 mole of the heaviest atom ( ununoctium, a mole is weight 294 gram) is:

4.767 x 10^15 degree ~ 5 x 10^15 degree = 5,000,000,000,000,000 degree

a very huge number!!

To see how hot it is, we can compare this with some known temperature.

Boiling Point of Gold is about 3,000 degree

Melting Point of diamond is about 3,500 degree

Boiling Point of diamond is about 5,000 degree

The core of earth is about 7,000 degree

The sun's surface is about 6,000 degree

The sun's core is about 5,000,000 degree

Notices that at the sun core, nuclear fusion is taking place. This is one of the violent reaction is the universe.

However, this is the classical view.

If we review the theory of getting the temperature. the temperature is proportional to K.E. instead of speed square. Since according to the special relativity, the Kinetic energy is corrected and not just the square of speed. Other speaking, the classical kinetic energy, which is equal to half of mass times speed square is for low speed. For high speed, the classical formula is not correct. Thus, the kinetic energy is not limited by the special relativity, but the speed. Therefore, there is no highest temperature.

The story does not stop in here, if we look a more closer look on what happen under high temperature. First, when temperature getting higher and higher, the pack of particle hits each others more frequently, and harder. Around 9,000 degree, atom no longer exist because the electrons are kicked out, and we called this, plasma. around 20,000 degree, plasma no longer exist because nuclear are broken, only protons and neutrons are left. At even higher temperature, protons and neutrons fall part and quark is left. Although we not really observed quark, we believe its existence. At very very high temperature, a hit of quark may produce many other particles as well. So, how to treat this ? what physics law should be use?

2nd, if we treat it like classic physic (i.e. no interaction between quark), the mass term is greatly reduced by replacing a heaviest atom by a quark. 100 times lesser the temperature will be. If we use electrons, also very fundamental particle, the mass term will be deduced 2000 times.

3rd, we so far believe the quark and electron cannot be broken because they are fundamental particles, What if it is wrong?

4th, What is the definition of temperature? only by the kinetic theory? If we have only 1 particle, is there any meaning for temperature? if no, what is the minimum number of particle to define a temperature? That are all testing our understanding.

Another definition of temperature is giving by thermodynamic. The concept of entropy.

entropy = Boltzmann constant * Log ( combination of the system )

1/ Temperature = change of entropy per unit energy

In human language, which means, if we inject 1 unit of energy, How many entropy or how the change of possible combination of the system. And the change is equal 1 over temperature. Which mean, if the change is minimum or zero, we have the highest temperature. Thus, when you cannot change the system by inject more energy, the temperature is highest and equal to infinite. Make sense!!!

According to this definition, even a single particle or an empty space has temperature! But the discussion is already out of topic.

Another way to find out the highest temperature is by the uncertainty principle, which stated that

the change of energy * the change of time must be grater or equal to the Planck constant.

In this case, the highest temperature is around 15 x 10^31 degree.

So far, the highest temperature is still an open question.

Curiosity falling

Most of us, when getting in a new job or new thing will be excited at the beginning. we are able to ask many many questions, give many suggestions, wondering why things cannot go in this way but that way. We are so curious about the new world.

The excitement or the curiosity will soon fallen. May be because we learn much, more or less saturated or accepted the way it works. Or may be, we just used to it and getting bored.

Is it so called mature? professional?

No! It is so called "doomed". following routines, obeying protocols, working like a horse or cow is not mature, and not even professional.

One truly example of professional can be found in many creative industry. Look at a professor in research lab. The work is routine and boring, but a professional can always find a way of break through and improvement. That is the key point - innovation.

When you work without new thoughts any more, you better quite your job or change the position. Just helping you not become too old when too young.

a Plot

There is a chance for making big money via financial market.

Now a day, many protests in Hong Kong, conduced by the 4th generation, who are around 20 to 30 years old.

How about making the protests becomes violent?

Guess what will be happened?

The financial market will fall by this incident!

IF, we buy a short margin before a protest.

Than we join the protest and bring some molotov, mixed inside the crowd.

At some high point, we use it and make the protest become crazy, police flight with people.

Next day, the Stock market must be fall and we can earn many many money from it.

And most important, in the chaotic protest, we can make our hands clean and without getting caught.

Anyone try?

Of course, the execution of the plot will bring so much damage to democracy.

Fastest Speed?

According to Einstein's special relativity, the fastest speed in this universe is the speed of light in vacuum. This is true in the traditional definition of speed, which is the travel per time of travel. Consider the case in warm-hole (although it is just an scientific imagination, no observed evident for the existence so far ), a space ship can travel a much greater distance in given time. Even so, the traditional speed still obeyed. The situation is like taking a short cut. Your speed never excess the speed limit.

How fast is the speed of light? the numerical value is 299792458 meter per second. If we compare with a civil airplane, the normal cruising speed is around 900 km per hour, which is 250 meter per second. the speed of light is much faster by 1,000,000 (million) times! If a plane from Hong Kong to Tokyo takes 3 hours, light only take 0.01 second. Of course, light can never travel form Hong Kong to Tokyo, because the earth surface is curved. Moreover, if light can travel on the earth surface, it can run 7 and half cycles in just 1 second! Therefore, you can go to anywhere from anywhere less than 1 second.

The reason why nothing can faster than the speed of light is, a rather indirect reason, only massless thing can travel at the speed of light. And only non real things can travel faster. Thus, For real thing, which has real mass, cannot travel faster. I know it is not a good or logical reason. it simply reflects my limited knowledge but mathematics of relativity.

Many people may fall in a logical trap that "nothing can faster than the light". This is only partial correct because the missing of "vacuum". Think about the speed of light in glass or water. Because of reflective index, the speed of light is slower than that in vacuum.

In long history of human, this is quite amazing that there is a limit of speed, not by the technical limit, but imposed by theory. To see how amazing the result, simply think about what else in this world is limited? Through out technology, we think that we can make anything in dreams come true!

The understanding of limited speed affected our life and many other things, and also, limited a lot of other quantities.

Guess what is the fastest thing that human being has ever created?

Super car? Jet fighter? Spaceship? NO! is electron!

Scientists have built a thing called accelerator. Yes, this mechanics always accelerate things inside, like electron, proton, Helium nuclei. The fastest speed recorded is about 99.99999999% of the speed of light, but not exactly the speed of light. The time for taking an electron at this high speed require several days or weeks. This speed is only few meter-second slower than the speed of light.

Geometry in Jewellery Design

people want their diamond jewellery look big, but also cheap.

what shape looks big? may be counted on the volume. If the volume is large, than the jewellery looks big.

How to lower the cost? may be less diamond is cheaper. the diamonds are mounted on the surface area. Thus, the surface area is smaller, the jewellery will be cheaper.

So, what shape will give largest volume while lowest the surface area? Yes, a Sphere.

However, some people prefer the cross section projection is big. In this case, a flat surface can do the job.

Similarly, if the diamonds are only mounted on the edge. So what shape gives largest area while lowest parameter? Yes, a Circle.

Elastic plastic touch screen

many people still like to type on buttons rather than screen. they said type on hard flat screen feel no good, especially no feeling on what you type.

How about an elastic touch screen? when you have to type, that part of the screen will pop and curved a bit. when you press on it, it will lower and give back some push on your finger. it acts exactly like keypad.

This can also be extended for people who cannot use their eyes. the screen can pop up the letter, in big, so we can feel it with our fingers.

The curvature of the screen better be 1mm, so it can show real good letter, sharp and clear.

How? may be by air? by the Electrorheological (ER) fluids? the basic idea is just add a very thin layer on the top of the hard flat screen.
