When I was in school, Phds seemed to be about doing what the professor wanted to get done, not anything of one's own volition. I guess the trick is finding a topic that both you and your supervisor are excited about.

@PhysicsGuy I dont get it either.

@JohnRennie OK. Perfectly acceptable. Worth a try.... :)

Jiminion

Oct 14, 2016 16:20

@JohnRennie How does intrinsic curving work? What is the mechanism?

Jiminion

Oct 14, 2016 16:18

@JohnRennie Is it proven that space in intrinsic? Or assumed so because the extra dimension (extrinsic) has not been sensed?

Jiminion

Oct 14, 2016 16:16

@JohnRennie OK, will do.

Jiminion

Oct 14, 2016 16:07

@JohnRennie Sorry I didnt see it earlier.

Jiminion

Oct 14, 2016 16:06

@JohnRennie I could.

Paul Davies cites QM as the reason he believes the world is non-deterministic.

@ACuriousMind Is that from personal experience?

@AmithKK It shouldn't be hard to work out the diff. equation.

@dmckee I don't think we'd be able to see a micro-blackhole in space. (I'm referring to the really tiny ones - electron sized or whatever.)

Jiminion

Apr 26, 2016 14:57

@dmckee Yes, proof that they exist. Has anyone ever detected one?

Jiminion

Apr 26, 2016 14:56

Is there any proof for micro black holes?

Jiminion

Apr 26, 2016 14:51

@DavidZ Well, they give back the energy "borrowed" to produce the part./anti-part. pair.

Jiminion

Apr 26, 2016 13:50

So, does the particle/anti-particle notion mean that a 3rd particle can translate or 'jump', by merging with the anti-particle and the remaining particle taking it's place? Is HR then somewhat akin to quantum tunneling?

@NoahP This helps, in the sense it tells me what hawking radiation is NOT. At to what it is, I might need 15 minutes or so to grok QFT.....

@JohnRennie We were actually saying in a prayer, hoping you would appear....

Every substantive physics question (to a neophyte) turns into Feymann bitching at a reporter about magnets....

Jiminion

Apr 25, 2016 18:52

@ACuriousMind Hmm, so sort of like two wrongs making a right? ;)

Jiminion

Apr 25, 2016 18:48

@NoahP JohnRennie mentioned particles with 'negative energy'. I've never ever heard of that before. Ever.

Jiminion

Apr 25, 2016 18:46

@JohnDuffield Hmm. That's not a particularly good or encouraging sign w.r.t. your comment on the question....

Jiminion

Apr 25, 2016 18:46

@ACuriousMind The site should have its own search.... (but I've heard that b4)

Jiminion

Apr 25, 2016 18:45

@JohnDuffield So, are you saying Hawking radiation is not real?

Jiminion

Apr 25, 2016 18:44

@ACuriousMind Yep, I'm working on it. I still don't know if John Duffield thinks Hawking radiation is a farce.

Jiminion

Apr 25, 2016 18:44

(to avoid duplicate questions - SO needs a better searching mechanism. I've said this like a billion times...)

Apr 25, 2016 18:42

@ACuriousMind I'll delete if you want. (I might be a simpleton, but I can be reasoned with..)

Jiminion

Apr 25, 2016 18:41

@NoahP Ha. That was me....

@DanielSank Yes, a variation of a Groucho Marx line. (I think the original had to do with reading a good book.)

Jiminion

Apr 21, 2016 15:40

@JohnRennie I don't. I think it's a reflection of your efforts to explain very complicated subjects.

Outside of a dog, solving Physics problems gives me great comfort. Inside of a dog, it's too dark to solve Physics problems.

It seems to be all about the math. If the math works and is predictive, then the underlying reality (whatever that is) doesn't matter.

Jiminion

Apr 20, 2016 19:26

@JohnDuffield So fields REALLY exist?

@ACuriousMind It is part of a video showing stuff winking in and out of existence. It is supposed to be what's happening inside a proton (and responsible for most of its mass).

Jiminion

Apr 20, 2016 13:13

So this is a poor representation of vacuum energy?

@Martin If such a machine was developed at Wolfram, it would be "a new branch of science". :)
