Attraction by Jonathan Aylett

if an object’s mass
determines its gravity
explain butterflies

by Jonathan Aylett

An object’s mass is directly proportional to the gravitational force it generates, but in this haiku I am turning this on its head and asking why am I so drawn to something as light as a butterfly? The answer is obvious really (they are beautiful).

Renegade liquid

Renegade liquid –

negative mass pushing back

breaking second law.

 

One of the fundamental aspects of Newton’s second law states is that when an object has a force applied to it, it moves in the same direction as the net force. Khamehchi et al (2017) created a liquid of negative effective mass (a Bose-Einstein condensate) that breaks this principle: when it is pushed it accelerates towards the pusher.
