Grande Horloge Ronde Math Wall Clock

If you prefer interesting mathematical theorems and concepts over mindless number crunching (as can can be lacs in most other designs), then this might be the right product for you. If any of the items are unclear, please consult the list below for a lettre explanation and consider as a starting point for further investigation. 0 [sic!] - General Mathematics: By an amazing identity of Leonhard Euler, this expression is equal to 0. It is by many considered as one of the most beautiful equations in mathematics. 1 - Axiomatic Set Theory: The set that contains only the empty set. This is how 1 is defined in von Neumann's construction of the ordinals. 2 - Algèbre linéaire : The dimension of the set of complex numbers, when as real vector space, is equal to 2. The most natural base consis ts of the two element 1 and i. 3 - Graph Theory: The chromatic number of the Petersen graph is equal to 3, which means that its vertices can be colored three colors that no two wo wo wo vertices et the solicolor. Incident ally, the Petersen is famous bug a notorious coexample to many 4 - Combinatorics : The rate of exponential growth of the Catalan numbers is equal to 4. These number remarkable because they occur as the counting sequence of literally hundreds of different combinatorial structures. 5 - Geometry : There are exactement 5 platonic solids, that is, regular et convex polyhedra. They are named after the number of faces tétrahedron (4), hexahedron (6), octahedron (8), dodecahedron (12) et icosahedron (20). 6 - Number Theory : For any natural number n, Euler's toquoction function tells us how many numbers there are in 1,..., n which are relatively prime to n. Since n = 7 is itself prime, there are 6 such numbers, namely 1,2,3,4,5,6. Any efficient algorithm for computing this function would immediately break the widely used RSA encryption scheme. 7 - Probability Theory : en expectation, rolling two customary dice results in a 7. Inally, the Mathematical Theory of probability has its roots in trying to understand games of chance such rolling dice and flipping coins 8 - Coding Theory : The number 8 has the representation 1100 in binary Gray code. Compared to conventional binary encodings, Gray codes have the sometimes desirable property that the encodings of two consecutive numbers differ dans exactement 1 bit. 9 - Analyse réelle : This is a convergent infinite series. Its limit is lacs to be equal to 9 by using the formula for infinite geometric series 10 - Analyse ex : Cauchy's Coefficient ula formuws to extract of the Taylor expansion an analytic function. Note tchoose 1 + z) élever 5 is the generating funating for the binomiction (5 choose 1), ... (5 choose 5). 11 - Langages formels : The depicted string belongs to the regular language of hexadecimal number literals . The semantic value of this string is 11.
