Today, the Schmidt-Cassegrain design, which was invented in the 1960s, is the most popular type of telescope; it uses a secondary mirror that bounces light through a hole in the primary mirror to an eyepiece. The second type of compound telescope was invented by a Russian astronomer, D. ...

What is Einstein's theory of gravity? What has been named after Sir Isaac Newton? How did Isaac Newton know John Wallis? What did Isaac Newton do to change the world? Who was Isaac Newton named after? What are some things that Isaac Newton invented?
He was only 26 years old. Without a doubt, Einstein was a genius. So was Isaac Newton -- as any fan of "Star Trek: The Next Generation" can tell you, he invented physics. He also played a big role in the development of calculus, which some people have trouble ...
But on Earth, there are other forces to consider, chiefly gravity. While air particles are extremely small, they do have mass, and so they are pulled toward the Earth. At any particular level of the Earth's atmosphere, this pull is very slight — the air particles seem to move in ...
How was Gravity's Rainbow received when it was released? In the Bronze Bow, how was the conflict resolved? How is the conflict resolved in A Sound of Thunder? How does The Turn of the Screw end? How does The Metamorphosis end?

So, given the limited window of opportunity for gravity to do its job while clothes are still hot, clothing that is heavily wrinkled will most likely still be wrinkled after home dry cleaning. The FreshCare kit even advises you to launder dress shirts professionally, given their propensity to ...
In a Steadicam, the articulated arm's gimbal grips the sled pole just above the center of gravity, in order to keep the camera from tilting in any direction on its own. The cameraman typically grips the sled pole at a point near the center of gravity, allowing him or her to control ...
Magnets and gravity work together to still the pendulum, and the beam is then projected through a light or prism. Some laser levels are equipped with electronic self-leveling sensors that boost accuracy and reliability, and they are ideal on a busy outdoor construction sight. For indoor jobs ...
