Rocket Engine Power

On Sept. 10, 2009, Nasa performed the initial full scale, full-duration test firing of the first motor for the Ares I rocket. ATK Space Systems conducted the successful stationary firing of the five-segment solid development motor 1, or DM-1. The Ares I is a crew launch vehicle in development for NASA's Constellation Program.

Make sure to hit that HQ button to watch a 22 Million Horse Power engine being test fired! If you want to fast-forward, T-10 is at 1:40.

The Universe in a Glass of Wine

Richard Feynman was probably the most influential physicist in the second half of the 20th century, best known for his contributions to the development of quantum electrodynamics. But was made him really unique was his ability to turn lectures into great story telling events.

Today my The Feynman Lecture on Heuristics DVD arrived and I am looking forward to watching that (again). But it is always worthwhile to listen to Feynman's lighter side as well: The whole universe is in a glass of wine.

A poet once said "The whole universe is in a glass of wine." We will probably never know in what sense he meant that, for poets do not write to be understood. But it is true that if we look at a glass closely enough we see the entire universe. There are the things of physics: the twisting liquid which evaporates depending on the wind and weather, the reflections in the glass, and our imaginations adds the atoms. The glass is a distillation of the Earth's rocks, and in its composition we see the secret of the universe's age, and the evolution of the stars. What strange array of chemicals are there in the wine? How did they come to be? There are the ferments, the enzymes, the substrates, and the products. There in wine is found the great generalization: all life is fermentation. Nobody can discover the chemistry of wine without discovering, as did Louis Pasteur, the cause of much disease. How vivid is the claret, pressing its existence into the consciousness that watches it! If our small minds, for some convenience, divide this glass of wine, this universe, into parts — physics, biology, geology, astronomy, psychology, and so on — remember that Nature does not know it! So let us put it all back together, not forgetting ultimately what it is for. Let it give us one more final pleasure: drink it and forget it all!
