A fantastic invention or fantasy?
An Italian inventor, Andrea Rossi, claims that a 1000 MW nuclear reactor, being constructed in Greece, will become operational in October 2011. I hope he is right; how can one not be happy to have electricity which is ten times less expensive than from coal, and without any pollution? But I am...- kowalskil

Graduate Investigating the Potential of Nuclear Fusion
The field that used to be called cold fusion is now called CMNS (Condensed Matter Nuclear Science. Below is the link to recent reports submitted by CMNS researchers. http://www.iscmns.org/CMNS/JCMNS-Vol4.pdf .- kowalskil

Undergrad Is Newtonian Mechanics enough to explain KE transfer in collisions?
The term "collision" is often used for situations when no contact occurs, for example an alpha particle being scattered by a gold nucleus, or on a hydrogen nucleus. The impact parameter is most often different from zero. -

Undergrad Is Newtonian Mechanics enough to explain KE transfer in collisions?
P.S. In other words, which particle is moving faster, more massive or less massive? -

High School Why Don't Waves Freeze in Water?
A "standing wave" is not the same phenomenon as a "wave." The net energy flow is zero, in both directions.- kowalskil

Engineering equivalent to ArXiv?
You are correct. There is no quality control; anyone can post what they want. By "equivalent" I meant a site at which one can store preprints, or unpublished papers.- kowalskil

How harmful is nuclear radiation? It depends on the dose received.
Dear Dmytry, 1) I agree on the "not worth arguing." No one expects radiation to be uniformly 0.25 mr/hr. In some places it can be much higher and in other it can be much lower. It depends on the time, rain, wind, etc. 2) Do you agree that quoted numbers--for the expected biological...- kowalskil

Engineering equivalent to ArXiv?
Try http://vixar.org (spells like arxiv but backward). It is functionally equivalent. . . Ludwik Kowalski (see Wikipedia) http://csam.montclair.edu/~kowalski/life/intro.html- kowalskil

How to do things on this website?
1) I am a new subscriber and I to know how to generate the list with links to my messages. The "Advanced Search" button, which I clicked, did have a box for entering my username. I entered it and clicked the "Search" button. But this did not produce the list I wanted. What should I do? 2)...- kowalskil

How harmful is nuclear radiation? It depends on the dose received.
1) That is correct, Dmytry. The two numbers I quoted were reported on specific days in specific locations. Theyare indeed much lower than at "the hottest spot." 2) I agree that the factor of two is not important. The needed exposure time (to get the best diagnosis), for a woman with a larger...- kowalskil

What follows should be shown an explained to all who discuss "dangerous nuclear radiations." Yes, I know that these numbers are well known to most people on this forum. Discussion of nuclear radiation should be quantitive, not qualitative. ================================================...- kowalskil
