Complex number - In mathematics, a complex number is an expression of the form a + bi, where a and b are real numbers, and i stands for one of the square roots of negative one (−1). The real number a is called the real part of the complex ...

Split-complex number - In mathematics, the split-complex numbers are an extension of the real numbers defined analogously to the complex numbers. The key difference between the two is that whereas multiplication of complex numbers respects the standard (square) Euclidean norm (x2 + y2) on R2, multiplication of split-complex numbers respects the (square) Minkowski norm (x2 − y2).

P-adic number - The p-adic number systems were first described by Kurt Hensel in 1897. For each prime number p, the p-adic number system extends the ordinary arithmetic of the rational numbers in a way different from the extension of the rational number system to the real and complex number systems.

Imaginary number - In mathematics, an imaginary number (or purely imaginary number) is a complex number whose square is a negative real number. The term was coined by René Descartes in 1637 in his La Géométrie and was meant to be derogatory.

A Major New Megalithic Complex in Europe - A new megalithic complex has been discovered, second only to Carnac in size and importance in Europe. Set in the forested hill-country of the Istranca Mountains in Turkish Thrace, clustered around the sacred mountain of Muhittin Baba, lies a group of standing stone complexes of comparable complexity and size, with the total number of individual stones reaching over 2,000
