The Weakest Force
by Anton Skorucak and ScienceIQ.com
Did you know that gravity is the weakest force in the universe? Well, it's true! There are four fundamental forces (that we know of) in our universe: Strong Nuclear, Electromagnetic, Weak Nuclear and Gravitational. The strongest one is the Strong Nuclear force, which is responsible for keeping the nuclei of atoms together. About one hundred times weaker than the strong nuclear force is the electromagnetic one. This is the strongest force that we experience in our everyday lives. In fact, whenever we touch anything we experience the Electromagnetic force. The electrons in our skin repel electrons in whatever we touch through this force. The Weak Nuclear force is the one responsible for most decays of particles and nuclei - which is where radioactivity comes from. This force is about 10 billion times weaker than the Electromagnetic force.The weakest of all is the Gravitational force. In fact, Gravitational force is 10 thousand billion billion billion billion times weaker than the Electromagnetic force. Well, it sort of makes sense because if the Gravitational force were stronger than the Electromagnetic one, we would fall right through the floor!
X-Rays - Another Form of Light
A new form of radiation was discovered in 1895 by Wilhelm Roentgen, a German physicist. He called it X-radiation to denote its unknown nature. This mysterious radiation had the ability to pass through ...

Carbon Dating From The Skies
Determining the age of relatively recent fossils, those of plants and animals that lived tens of thousands of years ago, is not a guessing game but an exact science. By using carbon dating we can dete ...

The Doppler Effect
As any object moves through the air, the air near the object is disturbed. The disturbances are transmitted through the air at a distinct speed called the speed of sound, because sound itself is just ...
