String Theory ~ Are we all but just vibrating strands?

[fritzd]

What's up string theory fans? I'd like to share some news I found.

If you have watched many String theory documentaries or read books about it, you will know who Michael Green is. Well, he has just been confirmed as the next confirmed as the next Lucasian Professor of Mathematics, to succeed Stephen Hawking on 1 November 2009 at Cambridge University. Influential people who held the position previously were Isaac Newton, Paul Dirac, and Stephen Hawking, and of course many more.

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

pretty cool tho. too bad it wun be posibble within our life time . but there's a posible we can contribute to science a leave our name on stones, within our life time.

[mariaClara]

can i also theorize?

hehe..

diba naa man docu ani sa youtube noh?

[hizuka007]

o daghan jud sa youtube bai....

I agree. Michio Kaku is an amazing Science popularizer. He has this awesomeness when explains things. hehehe But now he has become more of a science media broadcaster like somebody who makes very technical things understandable to the public. I believe he is still doing research though. I'm sure he has won awards. hehehe

Mao lagi.. pero I guess that is just how it is. hehehe! Basin maka-abot pa ta.. hehe

mangutana lang ko sa inyo ba,...

sa tinuod lang wa jud ko 100% nakasabot kaayo aning string ba... ana sila nga we are made of vibrating strings, pero nganong circular man dili man endless straight line string?

For a long time now, Physicists, Chemists, Biologists, and Engineers have enjoyed what Quantum Mechanics has to offer. For chemists, it explains all possible chemical bonds and many more, for engineers they are exploiting what quantum mechanics has to offer (eg. electonics, etc), for biologists most of them are working hand in hand with biophysicists to understand the organic nature of life even more (eg. bio-imaging, optical coherence tomography, even tracking biomolecules inside a cell with quantum dots), and as for physicists, well they are working hand in hand with the previous people I mentioned to find even more applications.

The other physicists, however, are looking at quantum mechanics at an even more advanced level. These people are called fundamentalists according to my professor. hehe! The people on the previous paragraph are innovators. They are using quantum mechanics as a tool and extending or applying it just about to anything they can see.

So what about the fundamentalists? Well, we all know them because usually they become very famous. (Einstein, Heisenberg, Feynman, Dirac, and including the string theory and particle physicists of today) Anyway, the main problem they encountered is with Quantum Mechanics. If you use quantum mechanics as a tool, you will be satisfied. But if you ask why quantum mechanics is the way it is and try to work out the problem, you will go mad. I've struggled, myself in trying to understand quantum mechanics because I kept asking why. You will understand quantum mechanics if you just accept that matter is a wave. That's all. hehehe! Solve it like a wave, then you will be happy with your experiments.

As for these fundamentalists they are trying to understand everything. Matter is a wave but we don't really know what is behaving like a wave or which measurable parameter is behaving like a wave. We just know that there is a wavefunction. In electromagnetism, we know exactly what is wave parameter in light. That is why we understand electromagnetism so very well. So the fundamentalists, just thought about what if the waving matter is actually a one dimensional wave. So the wave nature in quantum mechanics is simply just a 1-D ensemble of 1D waves hence Strings! Why not infinite? Well, you know of course that your system must be bounded, meaning you must find your particle at a given spacial boundary. If it is infinite, then it just won't work. It means that your particle can be found anywhere in space.

That is as far as my knowledge can go.. Hope it helps.. hihihihih

UNSWA?!!!! .................. ako ay nalilibog na. science ra kaayo para nako

pero nakasabot ko gamay sa last... nya narecall napud nako gamay tong gitanaw nako na docu.. ^_^ .. tama diay bantog ra dili infinite kay naa ra man diay sa sulod pajud sa sub-atomic particle diay ning string... tama ba ko? mao man diay daw na ang nakapadistinguish sa usa ka properties sa particle....
okeh okeh ^_^....

I have a question, If molecule is composed of atoms and atoms are composed of sub atomic particles, then sub atomic particles is composed of string (theory) or nothing, then where is the thought/memory resides?

yep yep.. tama ka. hehe From what I know about neuroscience, memory is just with the the particular strengthening of the synapses connecting neurons with each other. So a certain strengthening pattern of the synapses of a large group of neurons will correspond to a memory. =D

OT: I took a Neural Networks course back in my undergrad. It's an interdisciplinary course in physics where the applications are outside of physics but the concepts of physics are applied. In the course, we were taught about the physical behavior of neurons in terms of the language mathematics. With that, we were actually able to simulate a neural network or how the brain works by programming a neural network. And in fact, memory is stored in the strength of the synapses or in terms of mathematics the value of the values of the weights separating neurons. We programmed a 2-D array of neurons. The idea is to train the Neural network with some training data then expose it into the real world. The neural network can then recognize the patterns. For example, facial recognition, character recognition, etc.... In our project before, memory was stored as a 2-D array of weights or simply numbers from 0 to 1. hehehe

dba naa neuroscientist nag perform ug experiment sa rats, nahurot lng nya kuha ang brain wla ghpon nya makiti asa dapit sa brain ang memory. kalimot ko sa neuroscientist but nabasa ni nko sa book: The Holographic Universe by Michael Talbot which i think is a physicist. or bcn outdated naning booka. na search ra diay kuning book sa google.

samot na managhan string theorists. hehe.

kinsa kaha ang nangaply. last year [oct] man to announce ni SH.

congrats to MG.

naa loop or circular strings. naa sad open ended. lahi2x cla properties.

naa sad cosmic string. kng infinite ang universe infinite sad ang cosmic string.

pro theory pa tanan ky wa pay na observe thru experiments.

honestly i had a hard time understanding wat ive just read here but
the gud thing is, i had fun reading it, it caught my interest, pushes my
mind to comprehend as much as possible these things not so common to me.
at least im trying. hehe

yeah.. he really deserves the seat.. hehehe! It also means that the scientific community is recognizing the potentials of string theory.
