Preliminary WSC poster

Above is a preliminary version of a poster showing World Solar Challenge teams (click image to zoom). I will update the poster as more cars are revealed. Cruisers are listed first, then Challengers, and finally the Adventure class.

This poster has been updated. Six times. It is also available with a white background:


The Scientific Revolution and the Origins of Modern Science: a book review


The Scientific Revolution and the Origins of Modern Science by John Henry

I recently read the 3rd (2008) edition of John Henry’s The Scientific Revolution and the Origins of Modern Science – an excellent, though very brief, survey (it is 114 pages, not including the glossary and index).

Henry tends to see considerable continuity between the “natural magic” of medieval thought and the emerging scientific viewpoint, which was based on experiment and mathematical analysis. Personally, I think that he overstates the case a little. It is interesting that he never mentions Giordano Bruno, who was one of those who held on to the older magical view (then again, Bruno was not a scientist).

Henry also puts emphasis on the emerging use of scientific instruments, such as the microscope and the telescope.


Galileo’s sketches of the moon, published in his Sidereus Nuncius of 1610

I was a little disappointed in the discussion of Galileo, which did not seem quite correct, but the main flaw in this book is its brevity. I’m giving it three stars.

New Carbon Minerals

The Carbon Mineral Challenge is a worldwide hunt to find new carbon-bearing minerals by 2019. An estimated 145 such minerals remain undiscovered. Both professional and amateur geologists can get involved. This poster shows some recent discoveries:

Very brief solar car update

During my travels, I temporarily have Internet access for a day or two, and I see that the official World Solar Challenge team list is up. Some teams in my list seem to have dropped out (most notably Megalux, sadly), while other teams which I have never heard of have appeared.

I will update my list after my travels are over. Meanwhile check out what Mostdece has to say. As I continue to travel, this blog will run on queued-up posts for a few more weeks.


The wash bottle


Washbottles, old (left, photo: Hannes Grobe) and new (right).

Wash bottles, in one form or another, have been a long-term feature of the chemistry lab. Once they were made of glass, and were operated by blowing. In more recent times, plastic squeeze bottles have been used.
