The art of Hamid Naderi Yeganeh 

Hamid Naderi Yeganeh is a student of mathematics at University of Qom in Iran. He likes to create beautiful images by basic mathematical concepts. 

Earthquakes and Math 

Earthquake scientists (seismologists) use circle geometry to locate the epicenter of a quake and logarithms to classify its severity using the Richter scale. 

Epicenter of an Earthquake 

The epicenter of an earthquake is located by using circle geometry and special devices called seismometers. 

Games of Strategy 

The strategy behind particular games, such as chess, sudoku, or mancala, can be mathematically analyzed as Combinatorial Game Theory. 

The Global Positioning System and Circles 

The Global Positioning System is based on common mathematical equations of distance and speed. Trilateration enables GPS receivers to find the latitude, longitude, and altitude of a receiver, anywhere on the earth.

Leonardo DaVinci and the Golden Section 

Leonardo DaVinci created many masterpieces that depicted the golden ratio and other elements of mathematics. 

Linear Programming 

Linear Programming is using linear equations and inequations to maximize profits and minimize costs. Linear Programming is an important part of operations research. 

M. C. Escher  Impossible Mathematical Art 

Playing with impossible spaces, Escher became an artist famous for abstract pieces that mystify the mind and play with our perception. Using his naked eye and basic art tools, he was mathematically correct, to the millimeter. 

The Mathematics of Art 

The link between mathematics and art can be realized by considering artists like Leonardo DaVinci and M. C. Escher, as well as through the golden ratio and the Fibonacci sequence. 

Ratios and Proportions Used in Medicine 

Nurses particularly use proportions on a regular basis when following doctor's orders. 

The Richter Scale  Measuring Earthquake Magnitude 

Earthquake scientists use logarithms when they measure the strength of an earthquake on "Richter Scale." That means that a magnitude 9 earthquake, like the big 2004 Indian Ocean Earthquake, is ten times as powerful as a magnitude 8 earthquake. 

Spelunking 

Spelunking is a recreational sport in which "spelunkers" explore systems of caves, either on land or underwater. This problem deals with the idea of finding a spelunker who has become lost in a system of caves. The general idea is that the spelunker is lost in a cave system that has been mapped out on previous expeditions, so that when a search party is sent in, they know all the corridors and paths that they can take within the system.
