Physics behind wind energy

Wind is the flow of gases on a very large scale. Wind is caused by the differences of pressure in the earth’s atmosphere. Wind is caused by two major factors on the planet earth. The first being the sun and the second being the rotation of the planet. The sun does not heat up the earth’s atmosphere evenly, as most of the solar energy is absorbed at the equator. When the air becomes heated it expands creating an area of higher pressure. Diffusion causes this area of higher pressure to move to an

Physics of Boring Air Bags in cars

We know that moving objects have momentum. Unless an outside force acts on an object, the object will continue to move at its present speed and direction. Cars consist of several objects, including the vehicle itself, loose objects in the car and, of course, passengers. If these objects are not restrained, they will continue moving at whatever speed the car is traveling at, even if the car is stopped by a collision. Stopping an object's momentum requires force acting over a period of time. When

The Physics of Terror

A great place to begin to understand the physics of nuclear weapons is with Einstein's most famous equation: E = m*c*c. This equation associates energy E with mass m. The constant of proportionality is the square of the speed of light c. Because c is rather large (3E8m/s), the equation suggests there is a lot of energy associated with even a small amount of matter. In fact one kilogram of matter contains 9E16 Joules of energy, which is roughly the amount of energy released by a hydrogen bomb. Ch

Stars and the Sun

The Composition of stars is a very important and interesting field for astronomers. Stars begin their life when an ordinary dense cloud of interstellar matter becomes unstable and begins to collapse. The composition of such a cloud of matter determines the composition of the star which results from the collapse. Astronomers study the spectrum of the Sun to determine it's chemical composition, since it is the biggest star we are familiar with. In the visible region alone, from 4000 to 7000 angstr

The bees Eye view

I have a very large interest in bees, so for my first blog post I've decided to research how bees see colors differently compared to humans. Through my research I have discovered that the color spectrum of bees is shifted when compared to the color spectrum of humans. Visible light is part of a larger spectrum of energy. Bees can see ultraviolet – a color humans can only imagine – at the short-wavelength end of the spectrum. So it’s true that bees can see ‘colors’ we can’t. Many flowers have
