Nanosuit superhumans

Nanoscience and nanotechnology are new fields with various promises and big impacts to be made upon the society. Other than the normal mundane nanosized robots that can self replicate and carbon nanotubes, the possibility of integrating them into an exoskeleton suit of human size and shape is intriguing and will have various impacts on the society as a whole.
In the future, a device can be worn as a belt and on activation, small nanobots will come out of the device to create a suit that covers the user’s body with specialised carbon nanotubes. This suit can be bullet proof, light and be equipped with weapons. In comparison with the world of fiction, it is the nano version of Iron Man! In short, nanotechnology allows the technical possibility of Superhumans to exist in our world. These superhumans can be a one man tank, with the strength to carry heavy things as the exoskeleton allows it, high energy lasers that can be placed on the arms, jets that be placed at the bottom of the shoes, and anything else that Iron man can do.
If the suit is in the hands of the “right” people, superheroes can easily exist in this world. However, the impact of the existence of Nano Iron-man in the world may be varied. The world might explode in laughter at the person with the nanosuit acting like a superhero. The other possible response is that the world takes the concept of superhero seriously. From this point on, we only have the comics to guide us. And almost all the comics treat the coming of Superheroes as someone to respect and to hail as some saviour. However, the opposite may be true. Superpowers like America may be worried that Superhumans harbour too much power that it would threaten the superhuman to stop and hand over the suit.
Other than having people with “righteousness” having the suit, there can be greedy and ambitious people that can get a hold on this much power. These are the supervillians in the comic books. These people can leave a very negative impression on nanotechnology and possibly trigger wars like the war on terrorism. In this scenario, if a superhero comes and successfully save the day from the supervillian, then people who laugh at the notion of superhero may start to take them seriously. Most probably a team of supercops will be formed and controlled by a certain country. This can also trigger the possession of the suits by countries and start the whole arms race again, only this time; it is to collect the biggest army of Supersoldiers.
Finally, if the suit is available commercially without the weapons, it can be the ultimate protection suit, transforming the human race to a race of superhumans. The function of cops and soldiers are reduced, and murder cases become rare.
In conclusion, the possibilities allowed by nanotechnology in this form are huge and may generate many possible responses from the society.

Fatal Deviation: Bleach versus OnePiece

Let's see, I've been playing this game from Sunday, when I got it from garena to... monay morning, then slept till monday night. After dinner, I and a few friends played for 11 hours straight till the morning, and I managed to stay up until the night watching OnePiece (currently at episode 325, started from less than 10 episode from the start of this sem) and fell asleep until wednesday. And i played more than I studied on Wednesday even in SPS room. Now I'm really need to curb this fatal Deviation as I got to prepare for 4 of my exams. The reading week has gone until Thursday. I'll catch up on the time I wasted playing!

How best to make the prospect of nuclear power in Southeast Asia come true

“Prospects of Nuclear Power in Southeast Asia” does include both nuclear fission and nuclear fusion. However, the speaker only concentrated on nuclear fission, ignoring nuclear fusion. The speaker highlighted various problems associated with the use of nuclear fission reactors, but I believe that all these problems can be dispelled with the use of nuclear fusion reactors.
The first problem is that of nuclear waste disposal. Nuclear fission produces radioactive wastes that have half lives up to thousands of years, making it hard to store them properly. However, the wastes from nuclear fusion would only have half lives of about 50 years and thus it only needs to be stored for a shorter amount of time before being released. The second problem of nuclear proliferation also disappears as Plutonium-239 is not produced as waste in nuclear fusion reactors. The third problem of danger due to accidents is also minimized as runaway nuclear fusion is impossible due to the delicate nature of its process.
Thus it is obvious that the advantages of nuclear fusion reactor would remove all considerations of implementing nuclear power in anyone’s mind. Just one major problem with fusion is that currently it has negative efficiency. Research on nuclear fusion is been actively done to overcome this problem. However various difficulties are being encountered with some estimate of a possible nuclear fusion reactor only at the year 2050. However, looking at the desperate need of a cheap and non-polluting source of energy, the speaker should also encourage the audience to contribute to the feasibility of nuclear fusion as soon as possible.
The physics major students can contribute by increasing the number of talents working on that field, the sociology students can help research on how best to overcome the psychological difficulties of the public in accepting nuclear energy, the economics students can help plan how best to implement the nuclear energy in the near future. The main question unanswered is how best to make the prospect of nuclear power in Southeast Asia come true.

Lesson from History

The speaker has shown that the coming together of different cultures can lead to the development and improvement of modern sciences. However, I believe history is studied to tell us something, for us to learn and to create a better future. Therefore the speaker should draw a moral conclusion from his study. The lesson that I can conclude is that the advancement that leads to modern science is unlikely by just relying on one culture, one civilisation.
The culture of civilisations at any time should be distinct enough to enable the thinkers and scientists of that time to think in very different ways. From there, the different view points on the same topics can be produced and when a meeting of culture happens, the ideas can be combined, argued, and compared to advance the best idea, theory or even create a better one with the ideas available.
I feel that the speaker did not make the connection of this to what is happening now.
With the advent of the internet and the trend towards globalisation, many cultures are meeting at the same time, thus producing a lot of output in terms of the advancement in sciences. Universities tend to hold international conferences and dialogues for researches, this way, a lot of ideas are communicated freely and progress are made fast. The surges of ideas exchanged and the increased advancement of science can be clearly seen now as in the case of the Large Hadron Collider where physicist from many countries come together to discover the fundamental theory of the universe.
However, as globalisation progresses, the cultures of the world are slowly unifying. Even though there will always be individual thinkers, it might be harder to think of the something that others had not already thought of as everyone tends to share the same unshakable unspoken assumptions. They simply cannot think out of the box. Then the progress of science would slow down considerably, and science might have to rely on the occasional genius like Einstein to break our everyday notion of the absoluteness of some principles like absolute time.
This implies that maybe it might not be very good for scientific advance that the world is heading towards globalisation. But certainly, more research needs to be done in this respect.
This research is important to clarify these questions. Does world peace or world government come at a price of scientific advancement? And if so is it worth it? Furthermore, will the momentum of science be stopped eventually and forced to turn back? Will the events similar to Asimov’s Foundation series in which a great empire collapsed due to lack of advancements of science happen? Is it inevitable or can we somehow avoid it?
Of course this whole speculation is based on the assumption that science is advanced based on different viewpoints of scientist. This is indirectly implied from the topic of the speaker, “The Dialogue of Civilizations in the Birth of Modern Science” and is also open to research.

Books for QM?

Hi there, my name is Alvin. I'm a 17 year old student from Ampang, Selangor, Malaysia. I have a great deal of interest in physics especially concerning Quantum Mechanics. I had been reading many physics books like Richard Feynman's the character of physical law, Fabric Of the Cosmos by Brian Greene, A brief history of time and so on. But I can only dream about all this without knowing all of the stuffs like QM and Relativity. So I would want to take the initiative to learn. I would like to ask if you have any suggestions of textbooks on the most basic and fundamentals of QM ? And afterwards the kind of books proceding from that ? And also what are the preparation on the knowledge that I must have before learning QM ? Something like Pre-QM. (form 5 work ?)

Thank you.


http://www.physics.nus.edu.sg/~phyebg/index.php?page=LQM

Here I believe the three books in this website are useful. After you finished them off, you'll be as knowledgable in QM as most physics undergrad in their 4th year. Well to tell the truth, you'll find them boring and totally unrelated to what you read on those popular books. The maths will be unfamilar to you and hard too unless you learn linear algebra.

And for your Pre-QM stuffs, I would recommend "30 years that shook physics" by George Gamov as a begining popular text (since you're fond of them) to get you familar with the history of QM. Then I can only say, read form 6 text book, the part that you'll know is important from your QM history background. Then read a University Physics Textbook. These kind of text books are thick and only usable for 1st years. However, to save some money, don't buy the thick University textbook, go for modern physics, the front few pages describes relativity and the rest are QM and it's implications.

So now I have provided some guidelines and key words. To show your initiative to learn, it's up to you to be resourceful enough to google them and find those books. And I think there are ebooks too, so try looking for the free books online before spending most of your savings buying a book.

And don't give up too soon if you find that you're stuck. Go slower and give yourself time to learn. Hope to see you in this field in the future. Meanwhile keep me posted if you got any difficulty.

Finally Report done.

How to score full As in STPM

I had been asked this kind of questions quite often. Now other than the material available in the labels of Helpful advice on academic stuffs, I think I shall make up some more on STPM, straight As stuff. But be warned, most of the stuffs here you should already know, so don't expect a secret formula here. This is kinda like kung fu panda if you know what I mean. It's a bit sarcastic here, I hope you don't mind.
Disclaimer: even if you somehow managed to follow all these advices, there is no guarantee of 4 flat. More importantly is you do your best, then whatever results you get, be contented.

1. If you don't mind having only 4 subjects, don't take 5. It's a risk. But if you're as hard headed as me or already taken it, then do your best. But don't worry anyway, even if you miss out on 1 subject out of 5, you still can get 4 flat, unless the subject is PA. Like what I missed.
2. Don't take Further Maths. It's a hard to score subject, and too little people in Malaysia take it, mostly the ones who consider themselves the smartest in their school or one of the smartest. So I need not say more, but if this is your 5th subject, then concentrate on the other subjects(to get 4 flat) if you find that you won't get A in this, but at least make some effort not to fail it. However if you're also one of those who consider yourself a maths genius, be my guest, take it. Here's the blog to read if you do take it:  http://furthermathematicst.blogspot.com/
3. Don't play the fool. Yes you can be active in CCA(co-curicular activities), but don't spend all day not studying. Ya, the most basic way of scoring, study more hours per day! Do your homework in school, during recess, whenever you can, do extra exersices, ask your teacher things you don't understand..... do I need to continue? Of course, if you're like me, who thinks that homework is a waste of time and don't do the extra self exercise, and going online everyday, then...umm.... make sure you score in your monthly tests.
4. Don't spend all day looking for job/uni/doing extra stuffs for your uni applications. Ya, devote your life to studying. If you think form 6 is a store house for studying, you aint seen Uni yet. But of course this is a unreasonable thing to ask of you.
   What for you want to get 4 flat? to get into uni of course. But if you aim for local uni, just do your CCA, if you aim for MIT, just do your essay now, if you aim for NUS, then....umm..... get good result. If you aim for outer univer, Ivy leagues, then find a job, do extra stuff, join competition in thing you are good in until the highest level you can. National, International..... train hard. Get king scout, get black belt........ all these....
5. Don't spend unnessary time having a boyfriend/girlfriend. Most likely you two are not going to the same Uni or same course. ( If you are, then congrats, you're an ideal pair) However if you already got one.... then manage your time well. Oh and be prepared for break ups, especially around the time of exams. So one way to avoid this is to agree to break up now and reunite after exam (warning: possible passion reduction after long time no see each other.)....... Ok perhaps it's not nice to tell people to break up. But anyway, you're lucky to have one.
6. Don't make an enemy in classes. you're going to spend around 30 hours per week in class, studying. So make sure you don't have someone you dislike in class. It's bad for your mental balance. and you might not absorb what the teacher is saying. However if you already have one, agree to make peace. And see a psychologist if you still can't stand his sight. Don't be too alarmed to do that, I did it too believe it or not.
7. Go for some International Olympiads. Search the net for them and go through my blog for them. The contacts should be within your reach if you're serious enough to google it. Oh no.... this has nothing to do with scoring full As. Ok so don't go (to get more study time). But be aware that you're missing a very beautiful experience.
8. On study places, if you're in Malacca, go to Tzu Chi, at RM5, you can sit there all day doing your work and enjoying your tea. No food there through, so be prepared. Or more popularly, study at your home, you room or anywhere you can sit for hours on end and keep on having the mood to study.
9. On studying with whom.... I'll say your friends of course. Go for some group study. That is a bunch of friends studying at a certain place where everyone is comfortable and can study continously for at least 5 hours. But if you're not with your friends, then study alone.
   It's not a crime, unlike shopping alone, which I don't think is a crime too. Oh ya, choose your friends properly, those who talk non-stop when in a group are to be avoided. Ideally it should be everyone doing their own work and anyone got a question can rise it up and the whole group or whoever's listening can think can contribute to the discussion. 10 minutes later, it should be back to individual studies.
10. Read some books on how to study. It's plentiful and contains all the nessary and basics skills on studying. I'm getting lazy here trying to explain the basics to you, but just that if you don't know them, then you shouldn't be here(taking STPM that is).
11. Don't waste time, do some reading in your car, bus, train...etc. And ok Now I can't take it........ Just use common sense and study. Ok, good luck!
