Brun's Constant Brun's constant is defined to be the sum of the reciprocals of all twin primes: Note that the prime 5 is taken twice (some authors don't do this). If this series was divergent, then a proof of the Twin Prime Conjecture would follow immediately. Brun proved, however, that the series is convergent and thus B is finite . Brun's result demonstrates the scarcity of twin primes ...

Heilbronn Triangle Constants The nth Heilbronn triangle constant is the smallest number for which the following holds. Given any arrangement of n points in the unit square, there is at least one triangle, formed by three of the points, with an area not exceeding . Goldberg considered the exact values of the first several Heilbronn constants, including and made several conjectures. Yang, Zhang & ...

Googolplex Funny and Imagination-provoking , said the critics once upon a time, and awarded me the Top 5% icon you see here, for being among the top 5 percent of all sites on the Internet. That was in 1995, and all links to their own pages are broken now, but that certificate was never revoked, so I think I can still wear it with pride. But I'm afraid that since their comment on my page has ...

Math Forum || K-12 Math Puzzles || Problems of the Week || Student Center For many years mathematicians, scientists, engineers and others interested in mathematics have played year games via e-mail and in newsgroups. We don't always know whether it is possible to write expressions for all the numbers from 1 to 100 using only the digits in the current year, but it is fun to try to see how many ...

The Number of the Beast Mike Keith The number 666, first made famous by the Book of Revelation (chapter 13, verse 18), has also been studied by mathematicians because of its many interesting properties. Here is a compendium of mathematical facts about the number 666. Most of the well-known chestnuts are included, but many are relatively new and have not been published elsewhere. The number 666 ...

Square root of 2 The square root of 2 is very important number in mathematics. However it is generally overshadowed by other interesting quantities like PI. While PI is the circumference of a unit circle, the square root of 2 is the diagonal of a unit square. The square root of 2 is, of course, related to PI as that sqrt(2)=2sin(PI/4). Fortunately, it is much easier to compute the numeric value ...

Apery's Constant Apery's constant, , is defined to be the value of Riemann's zeta function when x=3. This designation of as Apery's constant is new but well-deserved. In 1979, Apery stunned the mathematical world with a miraculous proof that = 1.202056903... is irrational . We will return to this shortly; let us first discuss Riemann's function in a little more detail. The zeta function can be ...

The Arabic numeral system Arabic index History Topics Index The Indian numerals discussed in our article Indian numerals form the basis of the European number systems which are now widely used. However they were not transmitted directly from India to Europe but rather came first to the Arabic/Islamic peoples and from them to Europe. The story of this transmission is not, however, a simple one.

Indian numerals Ancient Indian Mathematics index History Topics Index It is worth beginning this article with the same quote from Laplace which we give in the article Overview of Indian mathematics. Laplace wrote:- The ingenious method of expressing every possible number using a set of ten symbols (each symbol having a place value and an absolute value) emerged in India. The idea seems so simple ...
