Herman Trivilino's latest activity

Is this a rehash of your original question? Look again at the answer I gave you. The issue you are having trouble wrapping your head...

There's no way distinguish between being at rest and moving in a straight line at a steady speed. The two states are equivalent. It's...

Where do you get that from? It's more like life arose in many places on Earth at the same time after enough time had passed for several...

He also said that things should be made as simple as possible, but no simpler. I take your point about discussions and images and...

Should be ##dt=−2u/c^2\ du##

Not relevant. The speed of impact is what's given in this simple problem. Why make it harder on the OP?

It's not the acceleration itself that increases the energy. It's the force, and only if that force continues to act after the collision...

The thing that makes Einstein's relativity unique is the Second Postulate: Light in a vacuum always moves at the same speed regardless...

I don't understand what you mean by "relative to the speed of light"? We refer to objects, not speeds, when we speak of relative motion...

I was there when the technology for creating video content became available. The possibilities are enticing and the equipment (very)...

Schoedinger did his seminal work when he was at least 38 years of age. Very late in life for a physicist.

Interesting. So the issue of collapse is just an artifact of the nonrelativistic approximation?

Yes, but to the uninitiated, learning about mass involves sorting out its relationship to weight. In medicine and commerce they are...

Yes. Anyone who has ever taught introductory physics has encountered students who have trouble grasping the concept of mass, and sorting...
