Spacetime and Spin
einstein.stanford.edu — Many of nature's deepest mysteries come in threes. Why does space have three spatial dimensions (ones that we can see, anyway)? Why are there three fundamental dimensions in physics (mass M, length L and time T)? Why three fundamental constants in nature (Newton's gravitational constant G, the speed of light c and Planck's constant h)?

- devaka, on 05/12/2008, -1/+8Thanks, added to bookmarks. Will translate on Russian and publish on Sevastopol Technical University website. Article will be useful for their students.
- sungoddess808, on 05/12/2008, -2/+5Please be sure to reference the author and Stanford University as your source of information. I takes a great deal of time and effort to write a paper and the proper credit should be given. =)
- fermcg, on 05/12/2008, -13/+4In Soviet Russia great deal of time and effort writes YOU!!
(I'm trying to stop it, but couldn't avoid it)- punkcat, on 05/12/2008, -1/+1dont worry, im always a sucker for a soviet russia joke.
- MtheoryX, on 05/13/2008, -0/+1You're doing it wrong.

- arjie, on 05/12/2008, -5/+6I know! It's the Trinity! Now all we need is one unified theory so that I can claim that they are separate but one.
- Dichotomic, on 05/12/2008, -9/+3Fairly dense article, but extremely informative.
I had no idea that Faraday was an actual physicist and not just a character on Lost.- arjie, on 05/12/2008, -1/+6How did that happen? You can't even pass school here without knowing Faraday's law. I mean, if you passed you obviously knew it. And the farad is the unit of capacitance and all that.
- Dichotomic, on 05/12/2008, -0/+5I probably did know it at one time in the past, but it's been years since school and I haven't had to deal with it at all. The name sounded familiar, but I just didn't make the connection.
- arjie, on 05/12/2008, -0/+1I shouldn't have said that, I can't even remember what a ribosome is and I last encountered it five years ago. Hey, we all have awful memories for stuff we don't like. Peace. Dugg up for love, you know.

- karthikm, on 05/12/2008, -0/+2"The fabric of the Cosmos" by Brian Greene is an interesting book on space, time and spacetime.
Edit : The book is already listed in the "Further Reading" section. - JMellissa, on 05/12/2008, -0/+3Does this explain why time goes by so slow fast when we're having fun and so slowly when we're not?
- austin006, on 05/12/2008, -0/+11there are more than three fundamental constants in nature....?
epsilon-naught?
elementary charge of an electron?- lonewalker, on 05/12/2008, -1/+2edited
- tehhowch, on 05/12/2008, -1/+0Don't forget the masses of protons/neutrons/electrons, mu-naught, Avogadro's number, etc. Article should have just skipped that part.
- sstidman, on 05/12/2008, -0/+1What about Pi? Isn't that a fundamental constant of physics/nature?
- MuskokasFinest, on 05/13/2008, -0/+1Those are the 3 FUNDAMENTAL constants in physics/nature.
- LucasVB, on 05/12/2008, -0/+6I love science articles like these that don't dumb down stuff. Some of us aren't afraid of numbers!
Dugg, excellent stuff! - boogie606, on 05/12/2008, -6/+3huh?????
- Japadict, on 05/12/2008, -3/+3Heh, the stupid 'three' part really turned me off. Ah well, I'll probably come back and read this later. Why does it have three spatial dimensions? Because it does, how else could it be? Also see austin's comment, he's got some good points there too.
Ah well, I'll probably come back to this tomorrow and find its a great article. Still, is it just me or is the introduction a big turn off?- CrunchyDeluxe, on 05/12/2008, -0/+1Just you. The intro actually brings up an interesting point.
- groone, on 05/12/2008, -0/+2I dunno about all that but I know they left out kitty-corner, and all the smidgens (e.g.; smidgen-left, smidgen-right, etc.).
- o0joshua0o, on 05/12/2008, -1/+3head asplode
- monodogamous, on 05/12/2008, -0/+2Is this why the Russians where so hard pressed to make a perfectly round BB about 20 years ago?
- OfficialJoe, on 05/12/2008, -0/+3...because for all our mighty scientific power, we can still only manage to count to three?
- Wosat, on 05/12/2008, -2/+2Three is a magic number,
Yes it is, it's a magic number.

I've got an OK background in Electromagnetics, but I'd appreciate a quick explanation or a pointer to an article which explains some of these other terms (fermions, isospins, etc).
