Newton's first law
By: Gioia Degenaars
Sir Isaac Newton, an English physicist, astronomer, mathematician and philosopher is credited with creating three laws that govern the natural world in terms of energy and motion. These laws are the basic foundation of many physics discussions and calculations. His first law is the most...

Probability of life on other planets
By: Steven Mars
An equation for the probability of detecting intelligent life on other planets was devised by Frank Drake in 1961. This equation estimates the probability a signal from another planet can be detected if they are advanced enough. The equation is N=RxFpxncxF1xFixFcxL. This equation has eight...
Achieving invisibility

Scientists have long debated many components associated with space. One debate has been whether or not components of DNA could spontaneously form in outer space. For decades scientists have not been sure whether or not DNA was formed in space or whether or not it...
Astro physics - Stellar Distances: Light years, parsecs and AU's explained
By: Jose Juan Gutierrez
Light years, parsecs and AU's explained Measuring distances is very important to obtain the properties of an object, for instance, the width of a street, the height of a building, or the area of a lake. To measure distances on earth, man makes use of...
