    Graduate After 103 years, Einstein's E=MC2 proved

    Does anyone know how the supercomputers did it rather than the empirical approach? Also, energy can also be converted to mass, but how? Is there any evidence of this occurrence? http://news.yahoo.com/s/afp/20081120/sc_afp/sciencephysicseinstein_081120235605

    Choosing a wife during tween years?

    In some cultures and especially in the past boys at age 9 or 10 choose their wife that they will marry later on. Why? An example is in Mongolia in the olden days. Not sure if it still happens now.

    Graduate Was Einstein's Pursuit of Unified Field Theory Fruitful in His Final Years?

    Hi All, I understand that Einstein pursued the Unified Field Theory for the last 30 years of his life, pretty much going against mainstream physics. Of course he never succeeded because the necessary foundation was not yet in place for this pursuit. Does this mean that the last 30 years...

    Programs Can I Get a Masters Degree in 2 Years?

    Masters degree? One of my friends has a B.S in physics, and a masters in mechanical engineering. He did it all in 6 years. Now surely an appreciable amount of physics relates to mechanical engineering, but is it typically that easy to complete another "separate" major like that? If I do 4...

    Graduate Assume that on earth we see something 1 billion light years away

    This is probably an elementary exercise, but my head spins trying to think about it. Assume that on Earth we see something 1 billion light years away (i.e. light took 1 billion years to reach us). To simplify, assume no relative proper motion, although the distance will change due to universe...

    Undergrad Viewing size of Galaxies 7 Billion light years away?

    Would a galaxy 7 billion LY away appear to be twice the expected size (angular size) as a consequence of the expansion of the universe? (Assuming the universe is 14 Billion years old). My math says yes. But of course, I am just using trig and geometry. Just curious.

    Hello, everyone. From what I understand at universities there are three terms in one year and students are required to take 5 subjects per term for 2 of these terms (ie. 10 subjects per year). So, if a student wanted to go to school for all three terms that would be 15 courses per year...

    Graduate Why Do We Measure Distances in Light Years Despite Time Dilation?

    Hi, This is probably a beginners question, but ill ask it anyway as it has me confused.I have read quite a few posts from clever people here (so I assume its correct) that the closer to light speed you get, the slower time gets, and also distances get shorter. Effectively meaning that, say for...

    Undergrad Calculus created in India 250 years before Newton

    ...that's what this headline says anyway. There's a lot more to calculus than infinite series... Also by the time Newton came along most of calculus had been discovered. Newton was the one who saw the big picture & showed that it was all part of the same theory.
