The fan and sail example is a situation studied in discussions of Newton's third law. [48] In the situation, a fan is attached to a cart or a sailboat and blows on its sail. From the third law, one would reason that the force of the air pushing in one direction would cancel out the force done by the fan on the sail, leaving the entire apparatus ...
Newton would need an accurate measure of this constant to prove his inverse-square law. When Newton presented Book 1 of the unpublished text in April 1686 to the Royal Society, Robert Hooke made a claim that Newton had obtained the inverse square law from him, ultimately a frivolous accusation.

An example would be a person on a foreign holiday encountering a friend they had not seen for years. In isolation this may feel like an impossible coincidence, but considering the wider petwhac (meeting any friend from around the same period, or meeting an acquaintance, or not meeting them but being told weeks later that they had been in the ...
Newton's tract De motu corporum in gyrum, which he sent to Halley in late 1684, derived what is now known as the three laws of Kepler, assuming an inverse square law of force, and generalised the result to conic sections. It also extended the methodology by adding the solution of a problem on the motion of a body through a resisting medium.
Newton's work in his Mathematical Principles of Natural Philosophy dealt with this in a further example of unification, in this case unifying Galileo's work on terrestrial gravity, Kepler's laws of planetary motion and the phenomenon of tides by explaining these apparent actions at a distance under one single law: the law of universal ...
The right choice of words is obvious, a message like TopShelf issued, showing remorse for the fight, apologizing for being a bad example and committing to learn, grow and do better.

We all bailed and started to swim back as it started pouring, and someone in a boat saw us rushing and came out to scoop us to safety. Scary s**t. Image credits: skepticallincoln
