This book is great! I love how it's written. I just read chapter 4: Trip to Canopus and found that extremely enlightening, thank you for...

Experiment shows that an accelerating clock continues to keep accurate time. This is the "clock hypothesis". It is tested by measuring...

Thank you all for the replies, I feel like I may be getting the idea.. The perception of time never changes for the observer, time...

The Laplace transform also has the same issue. If we take the Laplace transform of the equation above we get...

The ideal circuit has no real solution. The voltage at ##t=0## is undefined. Yes. Does that not clue you into the fact that the original...

Yes. The equations for the original circuit have no real solution. So it makes sense that it wouldn’t simulate without R2. Yes, I showed...

You are currently truly still in your reference frame. How do you currently perceive time?

In your sim you added R2. This is perfectly reasonable to do, but it is no longer the circuit that the argument is about. Once you add...

@Baluncore is right. If all of the components are ideal then the resulting system of equations has no solution. This is an “irresistible...

I think my post 24 gets them as far as they need for the simplest example that doesn’t “simplify away” the thing they are interested in...

It looks like ##V_{AB}=0## to me since they are directly connected by a wire. Is the triangle for ##I## just supposed to represent the...

That is just a matter of the choice of units. In Heaviside Lorentz units all three quantities have the same units which is even more...

Robert, I'm sorry to hear of the passing of your father. He and I had quite a few interactions over the years, all positive. He...

This is a good example of the principle of conservation of thread momentum, requiring no ongoing impulse from the OP.

The OP starts off with reference to constant velocity and constant acceleration. How can he be convinced that those ideas cannot be...
