In type I critical phenomena, the same phase space picture as in Section 2.1 applies, but the critical solution is now stationary or time-periodic instead of self-similar or scale-periodic. It also

When to use which?
August 11th 2007, 09:33 PM
When to use which?
if 5 card are dealt from 52 cards, determine the probabilty of getting 3 red cards and 2 black face cards.
The answer is 26C3(6C2)/52C5, but I got 52C5(1/2)^5(6/52)^2, how do you know when to use which?

Help with tiling
Help with tiling
• I've just converted one of my C++ AMP algorithms to use tiling, and I got a nice 80% speed up, great!
However, I'm unsure if I'm doing it correctly (most efficiently), since my code looks quite different from the various examples I have seen, and would therefore appreciate ... | {"url":"http://social.msdn.microsoft.com/Forums/vstudio/en-US/55478645-ac40-4700-bde6-b424746f982e/help-with-tiling?forum=parallelcppnative","timestamp":"2014-04-18T21:19:25Z","content_type":null,"content_length":"73766","record_id":"<urn:uuid:52f5c556-9929-489b-8d46-e96ab690bf71>","cc-path":"CC-MAIN-2014-15/segments/1... |
Enumerative Geometry and String Theory
String theory is a very contentious topic among physicists now, judging by the heat it has generated in scores of related books, articles and blogs over the last few years. Whatever its ultimate fate
in physics, string theory has led to a good deal of new mathematics and an upsurg... | {"url":"http://www.maa.org/publications/maa-reviews/enumerative-geometry-and-string-theory","timestamp":"2014-04-19T01:23:07Z","content_type":null,"content_length":"101667","record_id":"<urn:uuid:8b82cd5b-23a8-4ca4-89c6-5d54855a7fa4>","cc-path":"CC-MAIN-2014-15/segments/1397609540626.47/warc/CC-MAIN-20140416005220-0019... |

If given:p=prime and 2^(p-1)(2^p-1)=even perfect number, the fact that there are infinitely many prime numbers =>there are infinitely many even perfect numbers=>there are infinitely
many perfect numbers.
Another question is if there are infinitely many odd p... | {"url":"http://plus.maths.org/content/comment/reply/5925/4612","timestamp":"2014-04-19T07:23:02Z","content_type":null,"content_length":"20163","record_id":"<urn:uuid:eedbd5f6-96c0-4b71-a10e-b2a150de987e>","cc-path":"CC-MAIN-2014-15/segments/1397609536300.49/warc/CC-MAIN-20140416005216-00631-ip-10-147-4-33.ec2.internal.... |
