Sciences > Sciences (Other) Daylight Saving Time explained: 10 of 17
Daylight Saving Time started during World War 1 when the United States moved the clocks ahead one hour to save energy because of the extra hour of sunlight. It was stopped after World War 1 until the beginning of World War 2. It was stopped again after World War 2 until 1966 when Congress passed the Uniform Time Act. The Uni... More..
Sciences > Mathematics Calculus: The basics: 6 of 10
Calculus is the branch of mathematics that is a combination of algebra and geometry. It was discovered at the same time by the English mathematician and physicist Isaac Newton (1642-1727) and German mathematician and philosopher Gottfried Leibniz (1646-1716) in the 17th century. It is one of the most important branches of ma... More..

Sciences > Mathematics How to calculate probability with multiple dice: 2 of 3
The probablity of dice outcomes uses the regular six-sided dice that are used in board games. The six sides have one, two, three, four, five, and six dots respectively. The sides will have values of the number of dots each side-one, two, three, four, five, and six. The smallest value possible if two dice are used is therefor... More..
Hobbies & Games > Board Games How to read chess notation: 2 of 3
Algebraic notation is the most frequently used in chess tournaments today. The files (vertical rows) are numbered 1 to 8 starting from the white player's side. The ranks (horizontal rows) are numbered a through h. This means the square a1 is where the white player's queen rook is at the start of the game. Continuing, b1 is w... More..

The planet Neptune was discovered on September 23, 1846 due to mathematical predictions by Urbain Jean Joseph Le Verrier. Neptune was named for the Roman god of the sea. The data was used by Johann Gottfried Galle and Louis d'Arrest to successfully find Neptune. It is the eighth to the farthest planet from the sun (Mercury, ... More..
Sciences > Physics More math equations: 2 of 3
Physics is based on mathematics. Two of the most important are velocity and acceleration. If s=displacement, t=time, and v=velocity, then ds/dt=velocity and dv/dt=acceleration. Velocity is also called the derivative of displacement with respect to time. Acceleration is also called the derivative of velocity with respect to t... More..
Sciences > Mathematics Division by zero: Is it really impossible?: 30 of 43
Division by zero is possible, especially 0/0 because 0*0=0 and 0-0=0, which appears to prove that 0/0=0. However, the fact that 0*x where x is any number also equals zero appears to violate the laws of mathematics. The other integers are a little harder, but we can use a subtraction method to suggest that any integer when di... More..
