One of the things we often just accept about the world is that physical effects get weaker the farther away we get from them. Light sources appear dimmer, the gravitational force gets weaker, magnets ...

When Earth rotates as normal, the centripetal acceleration of the ground under your feet at the equator has the net effect of reducing the force of gravity on you, so you weigh about 0.3 per cent less ...

Getting a number of vendors to talk to each other, let alone align, is no easy feat. Adding academics and researchers does not necessarily make things easier. Now try adding to the mix a fragmented ...

Legend has it that Isaac Newton had the moment of inspiration that would lead to his theory of gravity when, on a warm afternoon, he saw an apple fall from a tree and wondered why it should fall down ...

Remember that time you were upside down in a roller coaster and, for exactly one second, your body left contact with your seat? The moment of exhilaration that made waiting in the long queue for that ...

If the universe contains more than three spatial dimensions, as many physicists believe, our current laws of gravity should break down at small distances Nothing seems more certain than the “fact” ...

A quantum probe for gravity: Physicists have detected a tiny phase shift in atomic wave packets due to gravity-induced relativistic time dilation – an example of the Aharonov-Bohm effect in action.

Long cardboard tube, such as an empty roll of wrapping paper, to make your ramp. It should be at least two-and-one-half feet long. A thin book or small wood block to raise one end of your ramp. It ...

If you’re superstitious, a black cat in your path is bad luck, even if you keep your distance. Likewise, in quantum physics, particles can feel the influence of magnetic fields that they never come ...
