Smarter Every Day: Detonation vs Deflagration #1

The Saiga 12 is basically an 12 guage in an AK-47 form factor.
Usually when people see a fireball they are quick to call it an explosion or a detonation. In actuality, what they've witnessed is a type of explosion called a "Deflagration". Many things are deflagrations. Logs burning in a fireplace are Deflagrating. The primer inside the shotgun is actually detonating. Lead Styphenate or Mercury Fulmanide are used in cartridge primers to start the pyrotechnic train in a bullet/shell. The primer itself is detonating, which kicks off the gunpowder which burns in the shell. Any powder detonations occur in the chamber. As the powder burns and begins to push the projectile out (gas seals with the barrel with something called an "obteration seal"). The powder in the barrel is also deflagrating.

Richard Feynman on Discovery of Neptune

(from a Lecture on Gravitation)

The key thing here is the connection between theoretical understandings of how the universe works and practical observations. Theories are used to make predictions. When the predictions turn out to be correct, we get some more evidence that the theory is on the right track. Here, Feynman talks about how the theory of gravity led to the discovery of the speed of light, and how knowledge of the effect of gravity on planetary orbits led to the discovery of the planet Neptune. Very cool stuff.

Domino Chain Reaction

A domino can knock over another domino about 50% larger than itself. A chain of dominos of increasing size makes a kind of mechanical chain reaction that starts with a tiny push and knocks down an impressively large domino.

Original idea by Lorne Whitehead, American Journal of Physics, Vol. 51, page 182 (1983).

See http://arxiv.org/abs/physics/0401018 for a sophisticated discussion of the physics.
