by 2002, 33 for every 1000 people.

Noncommutative Geometry, Quantum Fields and Motives
The scope of Non-commutative Geometry, Quantum Fields and Motives is titanic, as the title already indicates. Non-commutative geometry is of course closely associated with Alain Connes, and this has
been the case for many years now, certainly ever since his deep and d... | {"url":"http://www.maa.org/publications/maa-reviews/noncommutative-geometry-quantum-fields-and-motives","timestamp":"2014-04-16T15:00:27Z","content_type":null,"content_length":"100508","record_id":"<urn:uuid:91d7bb37-294d-4d03-9148-69ee3d826401>","cc-path":"CC-MAIN-2014-15/segments/1397609523429.20/warc/CC-MAIN-2014041... |
The philosophy of applied mathematics

I really do is use mathematics to understand the biological causes of migraines.

Numerical Integration - Simpson's Rule Error
For numerical integration, Simpson's Rule is:
