It does not slow down in water. Photons are absorbed and reabsorbed at the same rate, the difference is that water and other materials are different from a vacuum, so when they absorb and give off the same quanta of energy, they are again doing it in some direction that will cause this process...
Don't underestimate fairytales. I am reminded of:
So you seriously have to try to figure out the child and learn how much preparation you have to give the kid versus pure information of the type that you'd find on arXiv or scholarly journals.

Learning the counterexamples is an excellent suggestion. I sincerely doubt you should be memorizing all of the theorems by rote. Instead, being able to master the mindset that led to the creation of that theorem is what you should be aiming for, so if you can't teach it to somebody else via the...
Try Gerard ’t Hooft - how to become a theoretical physicist and my http://heybryan.org/bookmarks/Howto_physicist_July07.html with tons of links to resources on the internet for each of the topics.

What research steps must be taken before we are able to convert hydrogen into carbon, oxygen, potassium, and so on? My quick estimate is that we may be able to do this with a particle accelerator and bombard hydrogen with neutrons and protons, with some massive amount of energy loss in the...
Although not directly artificial brainery, I am maintaining a page on neurotech over at my website. Also, I've made a post to Slashdot re: neurotechnology that you may find interesting.
And, since we have for decades been using abstract neural models for our ANNs, we could easily hack up some...
Hi Richard, here's my stuff on calculus and related books of math:

* http://homepages.roadrunner.com/askmrcalculus/VisCalc.html
* calculus.org - The calculus page
* Textbooks and lecture notes...
It is interesting to think of liquifying a section of the body and then excreting the waste liquid as if it was nothing, especially cancers. This would probably involve the typical "introduce some poison, then activate the poison at the right location with some well-placed laser signaling."...
Mathematicians would be quick to point out to you that even physicists are focusing on 'junk knowledge' and that the only truths that you can work with are those of abstraction, such as in number theory, graph theory, etc. Speaking of which, I have recently been extending...
Please excuse me, but what are we talking about? Are we discussing ways of turning a telescope into an infrared camera? Or are we talking about producing infrared photons as a sort of laser?

The Journal of Algorithms story is a good one. Thank you for mentioning it.
Oh, I know you did not mean to put me in the spot. I was just typing and sharing ;) (I apologize if I gave more than necessary.)

Right. (Except it's not my neologism- it's semipopular apparently). I first heard of it on Slashdot on the University of Kansas copyright article (in particular, here).
When browsing through the indexes of degree programs offered by most universities, I found that chemical engineering...
