So I've been doing some review on special relativity and I realized that I never fully understood how simultaneity is relative in special relativity. Taking the thought experiment about a lightbulb being turned on in a train, I get that the observer in the middle of the train will see light...

Right, sorry if it was confusing but I actually need the combinations of those open formulas which normally I would assume to be just another 2^(previous # of formulas) except that I don't know what they correspond to in general terms. The way I thought of it before was to assume there was an...

My current understanding of schemata and structures in monadic logic is that, for example, if there are two predicate letters F and G that there would be (2*2)^the size of the universe of discourse possible structures as each object in that universe of discourse could take on any of the 4...

Hi, recently I've been doing some experiments on how and if frequency would affect the amount of energy lost by light as it passes through glass. So far, I've had some rather erratic results. Can someone clarify for me whether frequency does affect the energy drop of light passing through glass...

If I were to bend a cantilever by applying a certain amount of force at one end, would the distance it bends in a circle be linearly related to the torque resulting from the force? If not, would there be a measurable difference from being linear if I were to bend a, say, 0.5m long object with...
