    Graduate Inner product of rank 2 tensor and a vector

    I been reading some material that lead me to understand that it takes an inner product of a dyad and a vector to obtain another vector at an angle to the initial one... cross product among two vectors would be an option only if we are willing to settle to a right angle. After few days i...

    Graduate Is True Randomness Possible in Our Determined Universe?

    thats a very big question.. can there be a random thing in this universe ?? if the universe is run by a thing called a theory of everything. a simple and straight deterministic theory. but how can a deterministic theory fabricate a random phenomenon?! but surely we can see a lot of random...

    Graduate What would the universe be like if c were not uniform

    even now i think our universe doesn't add up everything to 'c' it jus appear that way. sorry i am a non believer. :)

    Graduate Advances in michelson morley interferometer

    when i meant advances i was thinking of modern upgrades to the experiments, rotating table like in the video i posted. or maybe usage of laser or something as jtbell has told.

    Graduate Advances in michelson morley interferometer

    hello, i am curious to know more about advancements that has happened to the M-m experiment, i am studying relativity and recently saw a http://youtu.be/7T0d7o8X2-E" of a modified interferometer. anyone knows a book/blog/file that talks purely about this. thanks.

    Undergrad Can ice go below zero degrees C?

    sorry i wasn't clear, when i was explaining what all happens at 0k i meant what would happen if a substance can actually go to 0k. zero entropy concept. and also tell me one thing, if no material can go to zero then the concept of "residual entropy" purely theoretical ??

    Undergrad Can ice go below zero degrees C?

    nothing much, all kind of vibrations stop. all its electrons will be in the ground state. that's what happens when an object reaches absolute zero.

    Is reality just electrical signals interpreted by our brain?

    you must have heard of hallucinations...try this video from TED [http://www.ted.com/talks/lang/eng/oliver_sacks_what_hallucination_reveals_about_our_minds.html] whatever the brain "sees" is reality. that's what many meditators experience [ traveling to elsewhere land, visiting dead, or seeing...

    Undergrad Why Isn't Gravity Infinite at the Center of the Earth?

    see, you know what happens when one of the objects its center with the other.. the attraction of gravity is same in all the direction. [that really depends on the geometry of the first object] now going by the equation, mathematically u can't place two things on the same place and call them two...

    Undergrad Understanding Coherent Waves: Frequency and Phase Differences Explained

    i think yes.. being multiples makes waves beat at the frequency that is HCF of both the frequencies.

    High School Calculating Conversion Rate/sec for X Particles

    you can't determine the conversion rate with just reading.. chances are there of going wrong, if its an exponential or depending upon the initial quantity. othrewise its normal way (-4 particle /second)
