News: Rocket Power Your Lazy Boy
Since the days of Archytas, rocket propulsion has been the Holy Grail of aeronautics. Thanks to Galileo's inertia, Newton's laws of motion, and the "father of modern rocketry," Goddard, space is not a complete mystery anymore. Rocket-powered aircrafts have evolved from the first liquid fuel rocket in 1926, to the Soviet R-7 which launched Sputnik, to NASA's Saturn V that propelled Apollo 11 to the moon. Today, even billionaire tourists can enjoy space, like Microsoft's Charles Simonyi and Cir...

How To: Experiment the law of inertia
Newtons proposed the concept of inertia. According to him an object at rest tends to stay at test and an object in motion tends to continue in motions unless acted up on by an external force. This is the principle of inertia. The tendency of the body to continue to stay as it was is called its inertia. You can demonstrate this principle with a simple experiment. As shown in the video when the hoop is pulled out the pen cap falls in to the bottle. Here the hoop is acted upon but the cap is not...
