Someone pointed a question out to me that tom roberts asked. I had explained that the formula for the force on a particle in a gravitational field is given by F_k = m ...

this quote of Einstein (?) has been misunderstood and misused by Patrick Reany "Physical concepts are free creations of the human mind, and are not, however it may...

It appears that Twin A goes off on one of his classical relativistic journeys. And he returns to shake hands with Twin B. Question, who actually made the trip? From the...

What is physical? In German an object is a "gegenstand": what stands against us. A physical object is what has a proper existence regardless of the existence of observers...

What is the explanation for the unification of the Electro-weak and Strong Nuclear forces with Electro-magnetism? Are they represented as solutions to Maxwell's...

I'm not really questioning whether it does or not. Just wondering if it has ever been directly proved that light speed = c/n. HW. www.users.bigpond.com/hewn/index.htm

Is there any scientific significance difference between the following two statements: 1) Traveling at relativistic speeds causes time to dilate. 2) Traveling at...

Gerald L. O'Barr had some comments lately about math vs physics as if the later were the same as the former since the former is the language of the later. There's nothing...

Quite an interesting analysis. Remarkably complete. Regarding de Broglie, you may be interested to know that his causalist philosophy did not pass away with him. He...

Here's a thought for what probably will be the ultimate in starship travel, at least as far as current theory allows. It is, of course, hydrogen-fueled, but instead of...
