1. ### What is your greatest achievement in physics?

Getting a job with my physics degree
2. ### Time travel into future possible

Why sleep, just go about your normal day. But if you really want to travel into the future, just get on a plane and fly coast to coast, you'll pick up a few seconds if you do it every day for a few years.
3. ### Brian Greene

Don't know if anyone watches the screen savers on Techtv, but Brian Greene was on tonight, not a bad interview. Of course, this forum is a Kaku site.
4. ### Speed limit (of light)

HallsofIvy you are correct, SR came before GR, so there was a limit on c before GR, but I think that rtharbaugh1 was asking about a rule in Newtonian Mechanics, which does not limit v or c, in fact c was believed to be infinite or atleast unmeasurable at the time of Newton.
5. ### Speed limit (of light)

No there wasn't any limit on c before GR, and you can't use part of GR for the event horizon and not the speed limit.
6. ### Speed limit (of light)

You need to remember that the event horizon is caused by the limitation of the speed of light, so if you could pass the speed of light, then you would change the event horizon. As for your an object whose accelleration was powered by the mass energy equivalence, as the object accelerates it...
7. ### Microsoft interview questions

The best interview question I have seen is "How would you move Mt. Fuji?" My answer, I would just wait, it is always moving anyway.
8. ### How to diffract a bowling ball

hehe good one
9. ### How to diffract a bowling ball

Yes it is true, I didn't give his name, or the University he attended, of course I also didn't say that, so that is probably the reason that I didn't give that information, but thanks for think of me when you quote other people. Hey, thats your poragitive. Have a good day.
10. ### How to diffract a bowling ball

I guess I'm missing the point, the limit on v is zero, or not moving, if it is moving, even the slightest, then it is considered moving. Note: Yes PHd's are given for work done, i.e. a paper based on research, or experiments, but De'Brolie basicly had a paper 1 sentence long, that wasn't...
11. ### How to diffract a bowling ball

And as a side note, DeBroglie got his doctorite, by writing a paper less than a page long, predicting the difraction of objects, without ever even attempting to prove it. Unfair I say.
12. ### How to diffract a bowling ball

Talking purely theoreticaly, you could diffract any object through a door way with the correct speed.
13. ### Multi-verse experiment

I would say that a multiverse is defined by a collections of dimensions seperated upon quantum splitting.
14. ### How to diffract a bowling ball

No, because it is rolling, and making contact with the ground.
15. ### Settle a bet:

The speed at which a object moves is dependent on the energy applied to it.
16. ### Multi-verse experiment

Ok so I was thinking that if a multiverse was created for every possible outcome of all situations, then it may be easy to detect them. Ok here I go, if I decide to run an experiment to ditect other dimensions, then I make a desicion to either create a device that sends a signal, or one that...
17. ### Speed of light

Actually what your missin is that the speed of light is constant everywhere. What happens in material is that light interacts with matter, i.e. is absorbed and emitted, making it appear to have slown down, but between those interactions it is still moving at c.
18. ### Medical Physics

Hey, thanks that is exactly what I was looking for.
19. ### Medical Physics

Hey everybody. I am interviewing for a internship at a neuclear medicine company and was wondering if anyone had any good links to current research in the field, or what the name of the main journal is.
20. ### Crystals that modify the frequency of light.

Isn't that what the predator used to be invisable?
21. ### Hitting Water at Terminal Velocity

A human will die at hitting the water at a minimum of 60 mph. Water has a very strong surface tension, trust me I've hit it at about 40 mph, it hurts like hell.
22. ### Project Idea

a rail gun is pretty simple, you creat two conducting rods that run parrallel to each other, then lay another one across them, and run a huge voltage through the two rails to shot the third rod, or disk or whatever.
23. ### Project Idea

Your best bet is to do a search for HERF devices, they are similar to what you are talking about, most emp weapons are pulse weapons, so keep it away from electronics, but a HERF gun is directional. Another, mabey more dangoures, but easier to construct is a rail gun, those can be fun and...
24. ### Atomic radii

you can calculate them, roughly by multiplying the contents radii
25. ### Photon structure - light decyphering

Ok, not sure on the nature of your post, but the photon is an elementry structure, so its not made up of anything.
26. ### Tell me the 3 greatest physicist u think

Galileo died almost completly blind from staring at the sun through a telescope, remember kids, just say no to science, science kills.
27. ### Equation handy for the recoil of an electron

Hey does anybody have an equation handy for the recoil of an electron passing through a magnetic field?
28. ### Tell me the 3 greatest physicist u think

I have to put 1. Newton Because of the work he did making calculus, while he did supress some ideas, he still did alot of great work, that we would be in trouble without. 2. 2. Einstien Same reason as everyone else 3. Wien He did alot for physics, astronomy, and chemestry.
29. ### Coriolis effect and water spin

The coriolis effect doesn't determine the way a drain drains. And they don't drain the same way everywere on the hemisphere. Now most drains do drain the same way, because they are made the same way, that is they are all spun the same way when polished, producing grooves that determine the...
30. ### A physics experiment with magnets and a vote pole

I voted nothing, but that is only if you can get the magnet spinning fast enough, most likely in a fast spinning magnet, you would simply see a wobble on the other magnet.
