I'd like to share some interesting find I came across while I was searching for something else. I know most people who are interested in the frontiers of science are not really interested in the rigorous mathematics where all the concepts came from. It is easier for anyone to get awed by a scientific concepts explained in a very good way like how Brian Greene, Michiu Kaku, and some other scientists gifted enough to do this does it. There are also some people who are interested to learn even more but don't have the necessary background to do so. Well here it is, if you want to learn and grasp the basic concepts of String Theory, then you must first grasp Quantum Mechanics. I found this introductory article to Quantum Physics and Multiverses. It is a very good reference for anyone who simply want to know more. Here it is:
Quantum Mechanics and the Multiverse

It doesn't really bore you with all complex equation in Quantum Theory but rather focus more on already known concepts which were brought upon by complex derivations. It really starts from the very basic ideas of Quantum Mechanics.

There is a part 2 to the link above. Quantum Mechanics and the Multiverse II
This however, will already start introducing some advanced math. But it explains everything it shows so that anyone can understand. But after that, it will all be concepts. =)

If you understand the concepts from the two links welll, then congratulations! You know have a working knowledge of Quantum Physics. hehehe! You can now move on to String Theory. You will also be able to appreciate String Theory with the given knowledge you have. hehehe

To give you an idea on the beast like equations in quantum physics. Check this out.

Although the equations show in this paper are mild, there are still more insane mathematics in physics. hehe! Mathematics in String Theory is even worst. =( hehe

Enjoy!

the links are excellent for amateurs like me. thank you kaayo.

so the LHC is to detect graviton.?? rayt

can we warp ? a faster way to transport /.?

[donna_belle]

naa lang ko question. will the Higgs boson also prove the string theory?

this is a tricky question to answer. hehe! because im still an young physicist. or shall we say im not exactly specializing in particle physics.. haha! but here is a good reference.
Peter Higgs and that elusive boson

From what I know, is that the Standard Model of Physics describes almost everything in the world except gravity. It describes the results of particle physics, chemistry, biology, and so on. (sidenote: The standarnd model is simply just quantum theoy applied to everything, eg, quantum chromodynamics, quantum electrodynamics, etc.. They just called everything as Standard model of Physics for simplicy) THe problem they encountered with the standard model is that through rigorous calculations and derivations, they found out that there must also be a particle responsible for the mass. The word particle is really not the correct way of describing my last sentence. hehe! Anyway, Peter Higgs, is the guy responsible this. This particle or mechanism has never been seen in experiment. So if they discover this particle, or whatever this is, they will comfirm the standard model of physcis and probably give string theory a good start. This is because all of string theory is based on the standard model and general relativity in the hopes of unify. So if the standard model proves to be a perfect theory then the string theory will be on its way to a unified theory.

But its just more than, I read somewhere that in the LHC they will also be looking for processes that disobey energy conservation. If they find this, they this might pave the way to confiming string theory. hehe

I hope this helps. hehehe =))

(OT: I just realized that Peter Higgs is from the University of Edinburgh which is very near the univeristy I'm studying right now. hehehe)

unsa sad pre-requisite sa quantum mechanics? hehehe.
im also in the process of reeducating myself sa physics, thanks to www.khanacademy.org. Prof. Liwag "the one" made it very boring and uninteresting for me. hahaha i hope wala si the one dire.

hehehe! I'm working with the on a topic in which the ONE got famous for. hahaha! Anyway, it depends on how deep you want to go in Quantum Mechanics. hehehe! You can look for books about Quantum Mechanics (QM). If you just want a brief idea about the processes and concepts and you don't want to deal with all the rigorous treatment, then you can look for QM books that are geared for scientists and engineers or QM books that is specially written for scientists or engineers working on different fields not in physics. It should be more than enough to give you an idea of everything.

But for a really strict requirement for studying introductory quantum mechanics at a higher level (if you are really specializing in physics), you will need Classical Mechanics, some Satistical Mechanics, and of course mathematics (differential equations, linear algebra, vector analysis, etc...). Then a more advanced from the previous one I mentioned would require you to have a background on advanced mathematics (special functions, operator mechanics, differential geometry, etc.....) I've literally almost gone crazy with the things I need to study right now in my MSc thesis. =(

The tricky thing with quantum mechanics is that some most of the things that are popularized by the scientific media (science documetaries) are concepts which are results from rigours calculations and derivations based on postulates in quantum mechanics. I remember in my chemistry class in my 1st undergraduate year, I really kept asking where those quantum numbers (orbital quantum numbers, spin quantum numbers, etc..Chemists use it to explain all the intermolecular forces involved in chemical reactions) in quantum chemistry really came from. I kept pushing the question on why those numbers??!! How did you come up with them? The small quantum chemistry chapter in that chemistry book we used simply summarized all concepts and just explained what everything means conceptually. It tried to make everything about quantum mechanics more tangible. hehehe! Anyway, as I kept asking my chemistry teacher about this and eventually she got pissed off and said, "GO ASK THE PHYSICISTS!" I finally understood the reason why those quantum numbers existed during my last undergrad year when I took the courses Modern Physics and Quantum Mechanics. So if you really want to learn quantum mechanics, first you have to ask yourself, "what will I need this for?" If you just need it for personal knowledge or you are just interested, then introductory QM books written not for physicists will suffice (even the internet is enough). If you are a reasearch engineer, chemist, biologist, etc.. that is currentyly working on a project that involves quantum mechanics, then you can look for those QM books written for interdiscplinary scientists. hehehe! I hope this helps. =))

[grovestreet]

i see. then thanks for the heads up. I'm really just after the practical knowledge and the thought process. But based from what you've said, i guess likay sa lang ko.... since i'm starting from the very basic of physics. hehe.

[cromagnon]

scientist on the house , free question .

whats ur view about god. ?

and from singularity theory. is the universe infinite. and that goes back to string theory. anyway.


in the near future there will be a huge apetite for energy , what are the plans for or how can we aquire

new sources of alternative energy. ?


also i have a great interest when the quantum revolution will come , but in the lng future.

it creates almost anything right , by changing the patern of an atom. from diamond to food , fuel.

[INFRACTION]

we are all energy

[dmelsie]

OT:oopps careful lang mga bay stay on topic lang this is science section \m/

anyway nakita ko docus about universe and naa ang discussion about string theory hehehehe wa nako gihumag tan aw kay almost 20gb hehehe daghan man sila gud

di basta basta sabton man gud hehehehe kadaghan sa mga strings hehehehehe

Hmm... I believe in God just as any other person who does. ngano? This is not the right place to discuss so diha lang kutob. hahaha close topic. hehe

There are already a lot of things going on. Steven Chu, Nobel prize in Physics 1997 was recently appointed by Pres. Obama as the Secretary of Energy. Before he did this, and after his Nobel Prize, he jumped ship on his research. He must have thought that he has already contributed a lot for Experimental Quantum Optics and thought that he should focus now on a different problem. Since then he has been involved in energy research. I don't know exactly what he is doing but he along with his group are doing some research for innovations in energy source for the future. You can do more research about what he is currently doing. hehe

Second thing that I know about is the Nuclear Fusion research program head by the European commission.
ITER - the way to new energy
This is a very interesting and promising program. A huge lab is currently being built in France. When we (me and my colleagues) our 1st master year in our program, the European Union(source of our scholarship) Head of Research and Technology (im not sure if that was the exact name of his title) gave talk to us about Science and Research in Europe. After that talk, it really opened my eyes on the attitude of western politics on science contrary to developing countries like Pinas. Anyway, most his talk was about this Nuclear Fusion program. According to him, European nations would spend as much as they can of research because they know it will eventually benefit in huge magnitudes. He also said that this ITER program aims in unlocking the possibilities of Fusion energy. As of now, its still a long shot. He said it will probably take 50 years for tangible results but they are willing to wait that long. If within 50 years, we can have free energy, then why not? For me, this is very promising.
Pages - ITERHistory

Their website contains a lot of interesting info. For all we know, maybe string theory will be an integral key in completing the research.

Very interesting that you brought this up, my prof in nanoscience was discussing about wavefunctions on a simple nuclear reaction. Anyway, the reaction involved an isotope of Hydrogen called Tritium decomposing into another isotope of helium plus an electron. I was asking if this was some sort of Fission process. He said it is not and will never be. He said its more of transmutation. Then talked about alchemy about those people in the old days dreaming of converting wood, perhaps into Gold. He said that we, having the right background, know that this might be possible. But why would you do it? Or why hasn't anybody thought about it? Because it is very expensive.... hahaha You cost in conversion could be even more than the value of your converted material and plus there is a chance that your converted material is radioactive. hehehe!

This is exacty the realm, of nuclear and particle physics. hehehehe! But diamond to food? Correct me if I'm wrong, I think this will be in chemistry. When nothing is different with the nucleus of the atoms and food. Diamond is just a unique Carbon lattice structure. Food? It's just carbon based organic molecules. So you are basically just adding atoms and forming molecules. hehehehehe
