Modern and Theoretical Physics

This question has been hard to answer. What do all you ppl. think ? Do what is presently done, i.e bury underground ? Or other means ? I personally think, that they should be packed into capsules and sent into space. Since there is no known life for a few hundred light years, the capsule can float through space and time, until the radiation is very weak and not harmful. Then the capsules can return and with some re-entry problems fixed, the element can be put back in the reactor ! i.e- U-235. The cycle repeats !

I just learned about sonoluminosity recently and found it quite fascinating. It's basically the production of photons from a bubble which is bombarded with high frequency sound (aka ultrasound). Furthermore the heat within these bubbles has been measured between 10,000 kelvin and one megakelvin, (other theories say higher still, but they don't have any proof really as of yet). These temperatures are high enough for fusion to occur. http://en.wikipedia.org/wiki/Sonoluminescence

I got this in a past exam and how exactly are you mean to work out the answer? And if charges moving in a circuit aren't negative then what are they? (I somehow doubt they are talking about positrons here) (I've got the answer here, but I don't know how to reach it.)

hey if anyone can copy and paste the formulas for: light, electromagnitism, gravity, quarks, leptons, dark matter, anti-matter. that would be a big help. also if any one can find bthe unfinnished equation of unification. einstine please copy and paste on to here. thank you for all of you help.

The research of behavior of electrons and positrons in accelerators has led us to concept of the electric wind. Movement of the charged particle in electric field is similar to movement of a sailing vessel in the sea. The sailing vessel cannot move faster than wind. Similarly, the charged particle cannot move faster than electric wind, i.e. faster, than speed of light. Experimentally detectable energy of the moving electron (or positron) is equal to the sum of two kinetic and three resonant energies. But only very small share of this energy turns into kinetic energy of rectilinear movement under action of force of electric wind. Other energy, which the electron gets und…

Hi, I was discussing the anthropic principle with a physicist friend, specifically Nick Bostroms argument 'Are you living in a computer simulation?', http://www.simulation-argument.com/ His response was, words to the effect, that the problem for physicists is one of storage i.e. to store data on fundamental particles you will need to use at least one of said particles. To be completely honest, its beyond me somewhat. I have read around this subject a bit (Bostrom, Tipler etc) and this argument of storage has thrown me completely. So, could we simulate a (our) universe or is it not physically possible? Hope that makes sense. cheers Rob

i was wondering if it would be possible to find a formula for electromagnetism? and light? i am working on a project that requires them both. also if anyone can give me any information on the two; i need to know if my theory could be right, that would be a real help. i am currently looking at the book Other Worlds. if there is any one that can help me with finding the two formulas at the top of the page, i would greatly appreaciate it. signed, B. Bourget

i was reading a thread about free will and got an idea: i think it may be a valid idea. there could be a set line of events that WILL happen no matter what. the circumstances of said events are probabilistic. perhaps if in the future a powerful enough computer exists and we could collect enough information, we could concievably predict any event, past or future. we colud possibly even use it to solve unsolved crimes.

I was wondering if it is possible to create movement on three dimensional plane utilizing purely photon energy. Would it make any sound? How powerful could it be and what would the "size to force" be?

In 2008, the LHC should confirm the existence of the Higgs boson. The accelerator is a circular type. The accelerated particles move in a circle until they reach sufficient energy. The particle track is bent into a circle using dipole magnets. The advantage of circular accelerators over linacs is that components can be reused to accelerate the particles further, as the particle passes a given point many times. However they suffer a disadvantage in that the particles emit synchrotron radiation. However the machine will barely touch the lower-limit that is placed on the decoupling energy associated with gravitons & dark energy particles. In order to test for fu…

Radiowaves, microwaves, and visible light are all part of the same big spectrum. If the only difference between these spectrums is wave-frequency, then how is it that some waves are able to pass through objects (like radiowaves), and light waves are blocked? How does the quantitive change of frequency cause a qualitative change of being able to pass through matter?

Source of energy? What follows below is an exchange I had with members in another forum. Can the scientists here help me. Can the kind and knowledgeable people here help me with information about energy feeding of nano machines -- socalled and so spoken about. Thanks for your goodness. yrreg aka Susma

I was wondering how mu metals (aka [math]\mu[/math] metals) work? I mean, for example, an antiferromagnetic material has domains which are aligned in a regular pattern whereby each domain is pointing in the opposite direction to the on either side, so it'd be like up, down, up, down etc. How are the domains aligned in [math]\mu[/math] metals that allow them to have their magnetic field absorption or blocking effect. I assume it is different from antiferromagnetic materials because it's a different name!

I have a question. What standard things do you think the final 'model' of physics should explain. Right now there are thousands of experiments discovering the tiniest minutia, but no mathematical theory is going to be able to explain one billion bits of minute experimental data. I can sort of start this off. 1. magnetic moment of proton 2. magnetic moment of neutron 3. magnetic moment of electron 4. g factors 5. Why the nuclear force range is what it is. 6. Fine structure constant. 7. Formula for gravity 8. Show how the fundamental constants of nature are related. 9. Equation of motion for particles 10. Explain masses of elementary particles 11. Exp…

Quantum wells are a very interesting branch of technology. You can read more about this here. Very interesting eh?

I have read on this subject only briefly in novels (Arthur Clarke's "2010: odyssey two", and Alexander Lazarevich's "The NanoTech Network"), so I'm interested if something like this is really possible. I really don't know much on the subject of chemistry, so I apologize if I say something that doesn't make sense. My first question is, is it possible to create a lattice of carbon, like a metal, that conducts electricity? My second question is, is it possible to arrange the structure of the lattice in such a way that it would have the chemical properties of a different substance? My last question is, what affect do the combinations of neutrons, protons, an…

Thought this may interest you guys: http://www.economist.com/science/displaySt...tory_id=3764508 And: http://physicsweb.org/articles/news/9/3/16 The Economist article was such a grand convergence. I found the articles looking for theoretical support for the p-B11 toroid fusion theorist of my previous posts. So many threads seemed to be coming together. Seward's ball lighting claim, the recent discovery of X and Gama-rays in lighting bolts at USF, I so wanted to see this progressive delineation of how toroids are expressed with the escalation of energy and scales. After reading Greyber's paper http://arxiv.org/PS_cache/astro-ph/pdf/9704/9704283.pdf…

I realise the latest atomic model is based on quantum mechanics but. Why does the atom, which is composed of pure oppositely charged electrical particles, not fuse together into neutrons similar to the suns nuclear process? What keeps the negative electron away from the positive proton? and why at the fixed bohr radial distance? Signed SpaceTime

Hi, I'm involved in another forum and someone has speculated on how something can come from nothing. It's a bit over my head, but I get the gist of it. I wanted to see what others think of it. It involves physics, so that's why i'm posting here. Here it is: If the origins of the universe did not follow physical law, there isn't much we'll ever be able to say about it based on facts and logic - it will remain a matter of opinion. But what if the origins of our universe did follow natural law and logic? If so, we may eventually be able to figure this out. So, what known physical laws (if any) would the origin of our universe from nothing violate? As far as I can t…

I am interested in learning quantum field theory as fast as possible. Is there anyone here who can help me learn it quickly? Assume that I already know classical electrodynamics. Thank you

My question is this. Is the BCS theory of superconductivity permanently wrenched in the minds of today's physicists, or do they expect the theory of high temperature superconductivity to also explain low temperature superconductivity. Thank you

Anyone know what Maurizio Consoli is going to do that is different than the many other attempts to prove that the ether did (not) exist? http://www.newscientist.com/article.ns?id=mg18624930.900&feedId=space_rss091'>http://www.newscientist.com/article.ns?id=mg18624930.900&feedId=space_rss091 or go to http://www.newscientist.com/ en enter ether in the search box. the title of the article is: Catching the cosmic wind

If black holes suck in energy, would the particles of matter and the energy particles mingle??? And would highly reactive gases collide and affect the space time continuant??????
