PeroK's latest activity

First, I acknowledge what you say about spacetime diagrams being confusing. So, some of my efforts have tried to develop additional...

This is a property of an infinite space. And infinite sets in general. For example, in one sense there are twice as many whole numbers...

If you look for the top 10 cosmology forums, then the first three will be in that list.

If ##\vec{F_{net}}## is the net force, and ##\vec{M_{net,a}}## is the net moment around the point ##\vec{a}##, then the net moment...

@PeroK . Stop complaining about AI - you're better by far!

There's only one of me. AI can proliferate and multi-task.

In flat spacetime (Special Relativity) it's conventional to talk about "observers" or "inertial observers". This often means...

I'm one of the few students, it seems, that finds spacetime diagrams confusing. The problem is that the diagram you have drawn is in...

I attempted to draw a Minkowski four-dimensional spacetime diagram, using frame K as the reference frame. I identified a point A with...

IMO, there are some good books that attempt to motivate the concepts of SR and GR with minimal mathematics. They are "Relativity...

Whoever then has the effrontery to study physics while neglecting mathematics should know from the start that he will never make his...

I have another point to make: Modern physics is very much guided by the mathematics, often in direct opposition to the "intuition" of...

It's rubbish, in short. That's why it doesn't make sense. This is analogous to saying that a hill is steep because the contour lines on...

The force of an impact depends on the elascticity of the materials, as this significantly affects the time of the collision. For hard...

Astronomy/cosmology simulations do two main things: 1. They rely on a set of assumptions about the physics involved, which are physics...
