PeroK reacted to palaphys's post in the thread Vertical Circular motion- A confusing question with
Like.
okay, so you are saying that the string can only reach the top slack, with the given speed in the question, that too in a hypothetical... -
PeroK replied to the thread Insights Fermat's Last Theorem.It would be amazing!

PeroK reacted to Bandersnatch's post in the thread I How to explain the strange pulsar in the Crab Nebula? with Like.
It's a pulsar wind nebula, with shock waves and a jet aligned with rotation axis. Not a vortex or a cone of radiation of the type that...

PeroK reacted to haruspex's post in the thread Vertical Circular motion- A confusing question with Like.
If you still are stuck on that after all the above replies, consider the bob as it approaches the top of the circle. It would be moving...

PeroK replied to the thread Vertical Circular motion- A confusing question.The mass is not constrained to move in a circle. In fact, it can't reach the top of the circle and have no KE at that point.

PeroK replied to the thread B Energy transfer water > air in a greenhouse.You need the specific heat capacity of air and water. And also to calculate the mass of something based on its volume you need its density.

PeroK replied to the thread B Why is displacement the integral of acceleration with respect to time? [corrected in thread].This is only for constant acceleration. The displacement is the (signed) area under a velocity-time graph. For constant acceleration...

The particle horizon refers to the current distance of the most distant (comoving) object that we can, in principle, observe today. The...

I don't see how this affects what I proposed. However, if you look at the bottom panel of Figure 1 in Davis & Lineweaver (which is where...

PeroK replied to the thread A Effects of perception.Do you mean importance or impotence?

PeroK reacted to Fra's post in the thread I Physicists disagree wildly on what quantum mechanics says about real… with Like.
I agree there is always something one can call intuition, just like in an inference system there are "implicit prior information" that...

PeroK reacted to kuruman's post in the thread Confusion In Writing Identical Particle Wavefunctions with
Agree.
This has me puzzled as well. The only thing I can think of is that, in the problem description, by "same spin" the author means "both... -
PeroK replied to the thread Confusion In Writing Identical Particle Wavefunctions.This I really don't get. The reason that two electrons may occupy the ground state of an atom is precsiely because they may be in the...

PeroK reacted to flyusx's post in the thread Confusion In Writing Identical Particle Wavefunctions with Like.
Thanks for your reply. I had wrote down the additional solutions when I originally solved it, but I thought I may have been wrong after...

PeroK replied to the thread Introduction - Excited to Join the Community!.In order to challenge existing theories, you need years of study. Theoretical physics is hard! That said, most people who put in years...
