The issues around nuclear power
By: Aaron Dollhausen
In 1934, Hungarian born physicist Leo Szilard proposed the idea of a nuclear chain reaction and its application as a possible weapon, which he patented with the British government that year. In the months of 1939 before the start of World War Two, leading German...

1. Introduction Aerodynamics is the science of air in motion and explains how and why an aircraft flies. It can be compared to, and contrasted with, aerostatics. 2. Aerostatics Contrasted with aerodynamics, aerostatics is the science which explains how and why a hot air...
Why objects float
By: Paul Morley
Understanding density is the key to understanding why objects float on water. If the weight of water displaced by a submerged object is less than the weight of the water displaced, then it will float.If you don't understand this then read on. By the...
Is time travel possible?
By: Jack Lee
People love to fantasize about time travel; it is a basis for hundreds, if not thousands of films and books, and many people even spend thousands on trying to do it. Why? Because not only could they become unbelievably rich, they could also change...
How electrical current flows
By: Mark G.
By the middle of the eighteenth century, electrostatics was a well established branch of physics. Several experiments had been conducted and many machines built that would produce through friction great amounts of charge giving sparks and electric shock. Electric shock was generated due to a...
Biography: Marie Curie
By: Wendy R.
Madame Curie was born in 1868 as Marie Sklodowska in Warsaw Poland, the fifth child of teachers. Marie stayed in Poland until she was 24 at which time she went to study in Paris. She became a physicist and chemist and eventually became the first...
Universal Law explained
By: Irrira Rikki
A COMPLETE BOND Explaining the Universal Law of Physics would be the Elemental Effect in which each and everything is Linked. We could take the largest circumference of a circle in any given direction within the shape of a round ball - call everything...
Understanding density and why objects float on water
By: Irrira Rikki
ACCORDING TO THE VARIABLES The smaller the mass within a volume of water - lets say a bucket - the less space it is likely to take up with air. In simple terms, the density of a small stone is heavier than a larger...
Intermediate physics: Explaining gravitational fields
By: Daniel Reneau
The greatest science teacher to grace the halls of Heritage High School, and one of the greatest influences on my scientific knowledge, once explained this to his class when studying the universe. It went something like this: Gravity can be explained easily by using a...

AERODYNAMICS Boys and girls, do you know that we are all surrounded? Well we are! We are surrounded all the time we are living on earth - by air pressure. All of us, suffers every day by plowing through this sea of air pressure at...
