If there are 9 million+ possible positions after 6 play moves, how many possible positions are there after 10 ply moves? I confess I had checked the Wolfram site, but on my PC I have a very hard time reading the formulas in the articles, they are displayed as some kind of exotic script, so I...

I don't agree with the number of moves being (218)^n at all. Nor do I agree with his analysis, Chess is far more complex than that. Consider just how much complexity is introduced by the choice of whether to castle or not: choosing either way can determine a vastly different set of further...

How many different sequences of plays (moves of pieces) are possible in the first ten moves of a chess game? I have seen numbers that range up to 30!, but I have no real idea how those numbers are derived or whether trhey are valid. In fact, I doubt if a factorial even has anything to do with...

That is a good possibility. I did not think of that. But I would still like to see if there are any other ideas. Thanks Pete B

The following phenomenon was posted on a discussion group forum to which I subscribe. The link below is to a UTube video that seems to show a very strange sunrise/sunset (not sure which it is). >>>Assuming this whole thing is not a photoshop fraud (which it may very well be)<<<, then is there...

Thanks, already have that one. I was hoping for something a bit more current and comprehensive. But I will go back and read that one again! Pete B

Can you recommend any other books that are as suited for the non-physicist as is the book "Fields of Color" you mention here? I have read and thoroughly enjoyed this book. I am not adverse to math in such a book (I am a retired electrical engineer and have had many couses on the level used for...

This looks interesting, but I am not sure I understand it. Does it resolve the nonlocality issues of quantum mechanics that arise in the viewpoint of relativity? “Roderich Tumulka (Department of Mathematics, Rutgers): “The GRW Flash Theory and the Conway-Kochen ‘Free Will’ Theorem.” In...

I have no dislike of Apple products (other than feeling they are exorbitantly overpriced), I just am a life-long Windows person, and see no great advantage to Apple over simply going to a Linux or Unix platform. I spent half my life developing data applications for MS platform systems, so I am...

Anything Apple is out (don't want or own any of that brand), as is anything Firefox. I have no problem with downloads of MP4 files rather than streamed, I can play them on my PC just fine. I should mention that the site you listed for the online education was great, I had seen it other...

Thank you for a very informative reply. The problem I have regarding streaming to TV is that my PC is on the opposite side of the home from my PC so it would not be practical to do that, but the device you mention or one like it may help. I will check out the list you posted, it looks very...

No offense taken. You assume all that is within my ability to carry out. I am not able to hook up my PC to my TV, the PC is not so equipped. Furthermore, what I seek is to do this without using a PC at all. I have download3ed and viewed many such videos; they are fine for observing on a...

I would have posted this in one of the educational forums, but the instructions there seem to indicate that only educators and mentors can post to those forums. So I will ask here: I am looking for sources where I can purchase home education courses on science topics, especially in the physics...

Here is the source I had for this puzzle, including the solution: http://tinyurl.com/468zcyn Pete B

That's correct. For the benefit of the others, would you care to explain how you arrived at that answer? Pete B
