Undergrad The paradox of symmetrical time dilation
I think it helps to suspend your disbelief for as long as it takes you to learn how it works. Putting your mental energy into arguments showing why it can't be true is a waste of your time. Trust me, it will all make sense in the end. PS, quantum mechanics is even worse.- gmax137

What did you do with your old college textbooks?
I just got a brochure in my mail from Zubal Books. I had forgotten about them. They say they will buy Physics, Math, Engineering...the list goes on and on. Monographs and periodicals... I haven't used them myself, but might be worth looking into at some point. Zubal dot com- gmax137

Looking for movies where mathematics actually matters
Does comedy count? There is a "Simpsons" episode where Homer has written on a chalkboard $$3987^{12}+4365^{12}=4472^{12}$$ Feel free to check with your calculator. Andrew Wiles may or may not have been amused.- gmax137

Schools How good and well-known is the physics program at RPI?
It has a good rep in nuclear engineering as well. I agree. I have known and worked with quite a few RPI alumni. This is so true. See if you can find out how many physics majors the school graduates each year. Use this to estimate the number of students you would expect to be in any...- gmax137

Undergrad What physics study path would help me answer my own hydraulics question?
For practical problems such as this, I would recommend you look at fluid flow textbook for mechanical engineers. EDIT: do a search on 'fluid flow pdf' to find a bunch of class notes. Scan thru them till you find one you like. An alternative would be Crane 410, a completely practical guide...- gmax137

Today I Learned
TIL that some railroad companies use "road slugs" -- locomotives without diesel engines. The road slug relies on the generator of its "mother" engine. This from the video which documents the recent derailment near Toledo OR. @Astronuc if you havent seen this one you may find it interesting.- gmax137

Undergrad Why is SI taught in US university physics courses instead of cgs?
no more looney than a newton meter or a foot pound. I have never forgotten the memory aid my professor drew up on the blackboard, something like this: "a dying centimeter says, 'erg' "- gmax137

How about this one: in Harahan, LA. I think they re-constructed Dickory since I lived there. I remember my GPS used to say, take Hickory to Dickory to Dock.- gmax137
