Herman Trivilino's latest activity

It can be really hard for a layman to determine the validity of a professional's website. Perhaps check the validity of the authors in...

A theory is used to make calculations. A theory is wrong if the results of its calculations don't match what we observe in Nature. The...

I don't think it's semantically correct. Too many physicists and authors have that habit. Certainly the tanker moves, and energy is a...

It really is an issue of convention. In my experience when the terminology is introduced it's either in the context of the 1st Law or in...

I don't think statements like this even make sense. Naturally-occuring things can be described, for example, as particles or waves. They...

A google search reveals a different exercise. Given two otherwise identical baseballs, the one with the greater internal energy will...

You would have to give us Feynman's exact wording of the question.

I think you are misinterpreting the minus sign. The minus sign in an expression like ##-\vec{a}## doesn't mean that the value is...

Let's see if I follow. Convey? Is that the same as interpret? Does the meaning of that word matter? My point is that none of that...

No. A theory is an attempt to describe the way Nature behaves. The words you use to describe that behavior have no effect on the theory...

You don't give a finite size to the electron. Last I checked the upper limit on the size was about ##10^{-18}## m.

The elevator in space is being accelerated by an external force. For example a rope is tied to the roof of the elevator and pulls on the...

Spacetime is a geometric construct that is very useful to physicists in describing and predicting the way Nature behaves. The aether...

You mean the conservation laws give different results. Conservation of momentum is a purely dynamical relation. Conservation of energy...

The third harmonic, at 3f, is the perfect fifth, in the octave above the fundamental. If you refer 3f to the octave it falls in, then...
