Pitch Drop Scientist Remembered For Record-Setting Experiment
August 27, 2013
Science professor John Mainstone died over the weekend at age 78.
The Australian was overseer of what is said to be the world’s longest running physics experiment.
It was a flask with “pitch” or tar set up to allow it to “drip” — but very slowly.
In 87 years only a handful of drops have fallen.
The test was to prove that pitch was actually a liquid not a solid, although it shattered like a solid.

Scientists Reach Milestone In Quest For Smart Windows
August 15, 2013
Smart windows change how much sunlight they let through on a hot day. Such windows could reduce the demand for energy by reducing the need for air conditioning.
At the Lawrence Berkeley Laboratory in California, Delia Milliron and her colleagues have been making microscopic crystals called nanocrystals out of indium and tin. As they report in today’s issue of the journal Nature, when you impregnate a special glass with these nanocrystals, you get a window that can block either the warming rays from the sun or the light rays from the sun, or both.
