Table Bay at midnight. Sailing by the stars Modern astronomy in South Africa begins with ships — and their unfortunate habit of colliding with the South African coastline. In a French ship stopped briefly at the Cape so that Father Guy Tachard could set up a small temporary observatory. He and his assistants discovered that most of the stars shown on their charts of the extreme southern sky did not exist at the marked positions, while many others were omitted altogether. The most notable early visiting astronomer at the Cape was Nicholas de la Caille, who spent two years charting the positions of almost 9 stars and measuring the shape of the Earth. As it was, Fallows was allowed a room in the town granary, and the government eventually granted him one of the pre-fabricated huts intended for settlers at Algoa Bay. From this hut originally in Kloof Street Fallows began observing the southern stars. By , it was part of a group of huts north of the new observatory building. Watercolour by Thomas Bowler.
History of Technology Heroes and Villains – A little light reading Here you will find a brief history of technology. Initially inspired by the development of batteries, it covers technology in general and includes some interesting little known, or long forgotten, facts as well as a few myths about the development of technology, the science behind it, the context in which it occurred and the deeds of the many personalities, eccentrics and charlatans involved. You may find the Search Engine , the Technology Timeline or the Hall of Fame quicker if you are looking for something or somebody in particular.
Scroll down and see what treasures you can discover. Background We think of a battery today as a source of portable power, but it is no exaggeration to say that the battery is one of the most important inventions in the history of mankind.

You know that I could never have been inside of your mysterious building out there, and I imagine you can be sure no one has told me its secrets. Yet I’ll bet that I can describe fairly accurately what is in there—not from seeing the machinery, but from knowing what must be done to oil in order to get the products you need.
You want to hear? Your crude oil runs into a tank of some kind, and you pipe it from there to a retort , some big vessel that you can seal airtight. Once it is closed, you light a fire under the thing and try to get all the oil to an even temperature.
The following examples do not fit any subtropes: In the video, though, the guy shoots spikes all around. It’s said that porcupines can shoot their quills — porcupines are not hedgehogs, however, and the popular belief is in fact false. Porcupines may have their spines dislodged while swinging their tails around because the spines are very loosely attached to the porcupine so that they’ll come out once they’ve been lodged in another creature’s skin; however, they don’t deliberately shoot their quills at a target.

It took us quite a while to trace the swords markings in our lexicon of 19th century European swords reference works. Curiously through our research these swords that appear to have survived the war in Russia were mostly in the Russian armoury store at Sebastepol during the war, and they were ‘liberated’ by the British soldiers from the armoury, and then used against the Russians in combat by the British.
Eyeglasses Through the Ages “The art of making a pair of spectacles was an achievement of monumental significance for mankind that has had an incalculable impact.

Show us the merchandise or you’re going to lose another head, dude. Sometimes they’re friendly and sometimes they’re not.
