Scientists Discover a Jewel at the Heart of Quantum Physics
Physicists reported discovery of a jewel-like geometric object or amplituhedron, that dramatically simplifies calculations of particle interactions and challenges the notion that space and time are fundamental components of reality.
Striped Toothpaste by Joost van Treeck, wikimedia: Invented by Lenard Marrafino in NYC, 1955, the two materials are not in separate compartments; they are sufficiently viscous that they will not mix.

Simultaneously, some of the pressure is forwarded to the stripe-material, which is then pressed onto the main material through holes in the pipe. http://en.wikipedia.org/wiki/Toothpaste #Toothpaste #Stripe
