Do you really think spiders sleep and dream?? When we are observing the behavior of a spider in its web ,they some times jumps or twitches their legs like a gost.To get an answer to this question,Daniela Rößler, an ecologist the University of Konstanz closely observed the behaviour of spider during the coronavirus lockdowns.Rößler became […]
Milky seas are also called maree which is a luminous phenomenon in the ocean which extend to a large areas of seawater (up to 6,000 sq mi or 16,000 km2) .Milky seas glow translucently (in varying shades of blue).It glows brightly enough to see from satellite. It was found In the year 2005, scientists announced […]
Borromean rings are three simple closed curves in three-dimensional space .These rings are topologically linked and they cannot be separated from each other. But when any one of the three rings break or is removed ,we get two unlinked and unknotted loops. These rings can be drawn as three circles on a plane. It looks […]
A Möbius strip ( Möbius band ) or Möbius loop is a surface that is formed by connecting the ends of a strip of paper together with a half-twist. This shape was discovered by August Ferdinand Möbiusin and Johann Benedict Listing the year 1858. The discovery of the Möbius strip leads to formation of the […]
Spherical trigonometry is a subdivision of spherical geometry which studies the relationship between trigonometric functions of the sides and angles of the spherical triangles which is a part of the great circle of a sphere. The cross-section of a sphere is a hemisphere and the plane passing through the centre is a circle, called the […]
The Steinmetz solid (mouhefanggai or bicylinder) is the solid common to two (or three) right circular cylinders of equal radius intersecting at right angle is called the Steinmetz solid where each of the curves of the intersection of two cylinders is an ellipse. Mouhefanggai in Chinese language means “two square umbrellas”.Three intersecting cylinders are called […]
Logarithmic functions are the inverses of exponential functions, and any exponential function can be expressed in logarithmic form. Similarly, all logarithmic functions can be rewritten in exponential form. Logarithms are really useful in permitting us to work with very large numbers while manipulating numbers of a much more manageable size. Logarithms were introduced by John Napier […]
In mathematics, pi is the ratio of circumference to the diameter of a circle. symbol π was devised by British mathematician William Jones in 1706 to represent the ratio and was later popularized by the Swiss mathematician Leonhard Euler. A pi is an irrational number and it is non-repeating. The pi value up to the first 100 […]
The Fibonacci series is a series formed by the Fibonacci numbers.The numbers in this series are given as 0, 1, 1, 2, 3, 5, 8, 13, 21, 38, . . . This series is named after a renowned mathematician Leonardo Pisano Bogollo, later known as Fibonacci. In a Fibonacci series, every term is the sum […]
