Using Euro coins as weights (2004)
Here is a cheap way to obtain a set of standard weights, for measuring weights up to about 100 gram, to an accuracy of about 0.5 gram : Use the coins of the currency of your country. Thus one can make use of the fact that these coins are fabricated in mass production, and because of that have not only a constant shape…

The Eclipse via Satellite
Yesterday’s eclipse as seen by the GOES-East weather satellite. I just grabbed the full-disk geocolor JPGs with wget and stitched them together with ffmpeg. BTW, If you’re wondering why the clouds remain in view as night falls to the East, it’s because the geocolor image is a composite of “true color” daytime and a…

Wind farms can offset their emissions within two years, new study shows
After spinning for under two years, a wind farm can offset the carbon emissions generated across its entire 30-year lifespan, when compared to thermal power plants. That’s according to a new peer-reviewed study published in the Journal of the Royal Society of New Zealand – which also shows within six months a turbine…

Learn perfect pitch in 15 years
It was not easy or quick, and there were so many qualifiers that, for over a decade, I didn’t really think I “deserved” the label. But as I got older, those qualifiers started dropping off one by one, and today I’m convinced that I have perfect pitch. I describe my musical journey and thoughts on what perfect pitch…
