    Probability of Radiohead being a great band given that The Beatles inspired them

    I could have posted this in the homework section but I didn't see a section on probability. Also, this is more of a general conditional probability question asked through an example. A band called Radiohead is inspired by an old band called The Beatles. 50% of music critics think the beatles was...

    How Does the Beatles' Legacy Impact Radiohead's Chances of Greatness?

    A band called Radiohead is inspired by an old band called The Beatles. 50% of music critics think the beatles was a great (G) band, 40% that it was moderate (M) and 10% that it was awful (A). These critics have also compiled the following table:0.8 0.1 0.1 0.1 0.9 0 0.2 0.3 0.5The table says...

    How Does the Generalized Eigenvector Formula Work with Duplicate Eigenvalues?

    I see that a generalized eigenvector can be represented as such: (A - λI)xk+1 = xk, where A is a square matrix, x is an eigenvector, λ is the eigenvalue I is the identity matrix. This might be used, for example, if we have duplicate eigenvalues, and can only derive one eigenvector from...

    What Causes a Rainbow Pattern When Heating Metal?

    I was just curious of something and was wondering if anyone could shed some light on this. I have a metal screen (like the kind you have on your water taps). I think it is made out of steel or something? Anyways, I was bored one day so I put a lighter up to it till it started glowing red...

    Traveling to Another Galaxy: Can You Get There Alive?

    as I don't have time to go through the derivation and what exactly gamma does I can tell you this: Gamma = 1/sqrt(1-(v^2)/(c^2)) This means gamma is always bigger than or equal to 1. For this question you want time dilation (obviously). You should know that when you travel faster...

    Clocks out of Sync (Special Relativity)

    so I reversed my t's and did the following: Looking for t' t' = (5/4)(-vx/c^2) (since t = 0 everywhere on the ruler) t' = (5/4)(-48/25c) = -12/5c sec <------------ which makes sense since it should be a negative time anyway... I think I forgot about that above lol. Just to...

    Clocks out of Sync (Special Relativity)

    wait a sec, I think I may have gotten my t's backwards.. Did I?

    Clocks out of Sync (Special Relativity)

    K, so say we have two 4 meter long rulers. One is going past the other at 3/5 c. From one ruler's frame: both backs of the 2 rulers line up at x=x'=0 and t=t'=0. If we want to find the time that the contracted ruler's front clock will read to the other ruler, is this how we would do this...

    Clocks out of Sync (Special Relativity)

    There are 2 identical 1m rulers (same rest length), and one if going past the other at some velocity. Each ruler has a clock every 10 cm. According to the fixed clock, the moving ruler's clocks will appear to be moving slow, and out of sync. (if t=0 when the rulers pass each other, then the...

    How Do Rotational Transformations Affect Coordinates?

    lol i sorry I know this is easy but for some reason I can't figure out where we get the y from. Is that a component? And is it the hypotenuse of something?

    How Do Rotational Transformations Affect Coordinates?

    Just a quick question: In my prof's lecture he drew two rotated rulers of the same length and showed that length is invariant under rotations. Obviously x^2 + y^2 = x'^2 + y'^2 = length of ruler, but how do we go from this to: x' = xcos(theta) + ysin(theta) y' = ycos(theta) - xsin(theta)...

    Medical Question about Nutrition and Brain Development

    Hey, I just had a quick question. If I was wasn't given the proper nutrition when I was grown up like most people (I'm 19 now), does that mean that if I was given the proper nutrition that I'd be smarter than I am right now? Would this lack of nutrition cause make brain to develop more slowly...
