The great Fletcher experiment
Given my current fascination with scale modeling, I got a set of Polish made papercraft templates that will enable anybody with enough patience to build a 1:200 scale model of a Fletcher.
History
A mountaineer’s story
The Fitzroy massif features one of the most impressive challenges for rock climbers: The magnificent Cerro Torre. This impressive granite needle is 3133 m high, and you may think that it’s not so high when compared with either Mt. Everest or the K2. But its south face is quite remarkable because it’s a 2000 m …

From Blaise Pascal to global warming
The Pascal (Pa) is the International Measurements System unit for the measurement of pressure. It is defined as one newton per square meter and the recommended unit for atmospheric pressure measurement by the World Meteorological Organization is the hectopascal (hPa), which equals one hundred Pa. The definition of Standard temperature and pressure conditions used for …
A matter of weight, or how the pound survived
Some historical background In my last article, I mentioned the avoirdupois pound, but I avoided any side story about this measurement unit to focus on the horsepower story. But after researching its origins and evolution, I discovered, IMHO, a fascinating story. The avoirdupois system is a system for the measurement of weight developed in the …
