How three guys recreated the D-Day Invasion

Thursday, January 24th, 2008

Here’s an amazing example of how computers and a little creativity can manipulate what you see on the TV screen. Watch this 4 minute documentary on how 3 graphic designers created D-Day on a shoe string budget for the BBC TIMEWATCH program “Bloody Omaha”… I could have done without the music soundtrack, but the way they put this all together is fascinating, and will remind you that everything you see isn’t always reality.

Amazing Chemical Reaction color changes

Sunday, January 13th, 2008

In 1973, this spectacular demonstration of a chemical reaction (a mixture of Malonic acid, potassium iodate, hydrogen peroxide, manganese sulfate and starch) triggered by an oscillator was perfected by Thomas Briggs and Warren Rauscher, two amazing high school science teachers. Over thirty-five years later, chemists are still trying to fully understand how it works.

What they do know: Several reactions take place at once. One of them produces iodine, which gives the amber color. Hydrogen peroxide reduces other chemicals into iodide ions. Along with normal iodine, the charged particles interact with starch to create it a blue-black color. The speeds of those transformations are constantly changing. As one overtakes the other, the color suddenly changes.
