Pariah Posted March 11, 2018 Author Report Share Posted March 11, 2018 Dinosaurs laid eggs millions of years before chickens made their appearance on the evolutionary stage. Ergo, the correct answer is: the egg came first. Quote Link to comment Share on other sites More sharing options...

Psybolt Posted March 11, 2018 Report Share Posted March 11, 2018 I just had parent-teacher conferences last week and I had a parent tell me that her daughter likes my class and me. She said that I am "hip" because I like super heroes. I had to stop the conference and say what a great world we live in now a days where super heroes make you "hip" in the eyes of a seventh grader. I certainly remember a time where that would not have been the case. Pariah 1 Quote Link to comment Share on other sites More sharing options...

Use perturbation theory to estimate the first-order change in the energy levels of the infinite square well if the well, rather than being square, is tilted by an amount +/- delta E around its center.

Pariah Posted March 14, 2018 Author Report Share Posted March 14, 2018 I didn't make it down to the first floor for the actual event, but apparently we had about 100 students participate in the walkout/protest today. About half of them, according to the administrator I talked to, actually had some idea why they were there. Quote Link to comment Share on other sites More sharing options...

Cancer Posted March 21, 2018 Report Share Posted March 21, 2018 I think you could torque a nonspherical object with that set-up, but I expect you would need many orders of magnitude more power, and the volume of space where force is exerted is really small. That last means that you'd have to have superhuman control over holding the "screwdriver" in space so you weren't e.g. applying torque to both "screw" and "nut" at the same time, and you have no sensory feedback to help you do that (you can't feel the screwdriver head slipping out of the slot, or whether bolt & nut are both rotating together in the hole, etc.). It's much easier to see an engineering pathway to levitation coveyor belts in a manufacturing context, which still something, but not the legendary doctor's tool.
