Weighted spring rising and falling.
This is an example of simple harmonic motion. The weight accelerates downwards under gravity, and is moved back up by the tension in the spring. The velocity of the weight is fastest at the midpoint and slowest (zero) at the top and...

A pulsar is generally believed to be a rapidly rotating neutron star that emits pulses of radiation (such as x-rays and radio waves) at known regular intervals.
A millisecond pulsar is one with a rotational period in the range of 1-10 milliseconds. As the pulsar picks up speed through accretion, it distorts due to subtle changes in the crust. Such slight distortion is enough to produce...
