WebIn 1915, Viggo Brun showed that the sum of reciprocals of the twin primes was convergent. This famous result, called Brun's theorem, was the first use of the Brun sieve and helped initiate the development of modern sieve theory.The modern version of Brun's argument can be used to show that the number of twin primes less than N does not exceed (⁡)for …

WebA mathematical constant is a key number whose value is fixed by an unambiguous definition, often referred to by a symbol (e.g., an alphabet letter), or by mathematicians' names to facilitate using it across multiple mathematical problems. For example, the constant π may be defined as the ratio of the length of a circle's circumference to its …

WebA mathematical constant is a key number whose value is fixed by an unambiguous definition, often referred to by a symbol (e.g., an alphabet letter), or by mathematicians' names to facilitate using it across multiple mathematical problems. Constants arise in many areas of mathematics, with constants such as e and π occurring in such diverse contexts …

WebEen priemtweeling is een getallenpaar (, +) waarbij zowel als + een priemgetal is. Voorbeelden hiervan zijn (,), (,) en (,).Men spreekt van priemgetallen met een hiaat van 2. Een hiaat is daarbij een afstand tussen een priemgetal en een volgend priemgetal +.Tussen deze twee priemgetallen is er geen ander priemgetal.

Web1919 – Viggo Brun defines Brun's constant B 2 for twin primes. 1921 – Emmy Noether introduces the first general definition of a commutative ring. 1928 – John von Neumann begins devising the principles of game theory and proves the minimax theorem. 1929 – Emmy Noether introduces the first general representation theory of groups and algebras.

WebThe Pentium FDIV bug is a hardware bug affecting the floating-point unit (FPU) of the early Intel Pentium processors.Because of the bug, the processor would return incorrect binary floating point results when dividing certain pairs of high-precision numbers. The bug was discovered in 1994 by Thomas R. Nicely, a professor of mathematics at Lynchburg College.
