175 years ago, the Foucault pendulum experiment caused a nationwide public science fad. Most people understood what scientists knew about the universe, but Foucault made it feel real. Science was ...

A recent study conducted at Tel Aviv University has devised a large mechanical system that operates under dynamical rules akin to those found in quantum systems. The dynamics of quantum systems, ...

[Nicholas Rehm] works during the day at the Applied Physics Laboratory at Johns Hopkins, Maryland, so has considerable experience with a variety of UAV applications. The question arose about how the ...

Reaction wheels are useful things, typically used by satellites to keep themselves oriented the right way up in space. Turning the reaction wheel creates an equal and opposite torque in the spacecraft ...

SOME four years since, while arranging a Foucault's pendulum for use in the class-room, it occurred to me to endeavour to obtain a permanent record of the experiment, and as the results were very good ...

The Earth rotates, and where you are changes how you see the universe. We are introduced to Foucault’s pendulum. Moving under the influence of gravity, over the course of a day the pendulum’s ...

PROF. GREENHILL gives currency to quite an erroneous idea, in last week's NATURE (p. 50). He says “in the Foucault experiment of the pendulum which shows the rotation of the earth, the slightest ...
