Mathematics and Art http://en.wikipedia.org/wiki/Mathematics_and_a rt http://en.wikipedia.org/wiki/Mathematics_and_a rt Some of Escher's tessellation drawings were inspired by conversations with the mathematician H. S. M. Coxeter concerning hyperbolic geometry. [54] Relationships between the works of mathematician Kurt Gödel, artist M. C. Escher and composer Johann Sebastian Bach are explored in Gödel, Escher, Bach, a Pulitzer Prize- winning book.tessellation H. S. M. Coxeterhyperbolic geometry [54]Kurt GödelM. C.

16. Fundamental Theorem of Arithmetic In number theory, the fundamental theorem of arithmetic (or the unique-prime-factorization theorem) states that any integer greater than 1 can be written as a unique product (up to ordering of the factors) of prime numbers.number theoryintegerup tofactorsprime numbers For example: 6936=2 3 x3 1 x17 2 and 1200=2 4 x3 1 x5 2 are two numbers satisfying the hypothesis of the theorem that can be written as the product of prime numbers.hypothesis theorem

17. Fundamental Theorem of Algebra Every non-zero single-variable polynomial with complex coefficients has exactly as many complex roots as its degree, if each root is counted up to its multiplicity.multiplicity Or every non-constant single-variable polynomial with complex coefficients has at least one complex root. Equivalently, the field of complex numbers is algebraically closed. polynomialcomplexcoefficientsrootfieldcomplex numbersalgebraically closed

22. What is knowable and measurable Interaction is what is important not consciousness, the universe continues now whether you are conscious of it or not. You can not know where something is and know at what momentum (velocity with attitude) to arbitrary precession at the same time. You can not know what the energy is and know what it time of emission or absorption is to arbitrary precession. The universe is pixilated around Plancks constant, h or ħ.
