Cipher Mysteries

Equal parts brilliant and frustrating, Rolf Willach's "The Long Route to the Invention of the Telescope" (2008), which reprises his featured sessions at the September 2008 conference in Middelburg, is a book formed of two stunningly different halves. Through his insightful and breathtakingly meticulous analysis in the first seven chapters, Willach dramatically reconstructs the history of optical craft in the centuries preceding the invention of the ...

I've just come back from 24 hours in Swansea, a town where, bizarrely, almost every road is one way (usually the opposite way to which you want to go). At the top of Mount Pleasant, students eke out their existence, one drunken stumble away from a 5-minute death-roll down Constitution Hill's 45 degree gradient. Swansea is the kind of place where (ideally) you'd like a hang-glider to get ...

People don't generally know a lot about Tycho Brahe, which is a shame. In most accounts of the history of astronomy, his bright star tends to get eclipsed by the twin 17th century supernovae of Kepler and Galileo. But scratch the surface of the story, and it's really not that simple... Brahe was a Danish nobleman with a singleminded desire - to understand ...

It's a mystery: when there is abundant evidence that people in the Middle Ages knew for sure that the earth was basically spherical, why has the myth persisted until the late 20th century that Columbus had to argue against Flat Earth proponents to gain backing for his voyage? And where did this whole mythology come from? In his fascinating (if all ...

In his 1959 book "The Sleepwalkers", Arthur Koestler painted a rather damning picture of Renaissance European astronomers and scientists, where the only person not sleepwalking was Kepler. As part of the process of tarring everyone else with the same soporific brush, Koestler derided Copernicus' famous "De Revolutionibus" as "The Book Nobody Read". It's true that only a small proportion of "De ...

OK, so it's not exactly Wikileaks: but following on from my very recent review of Albert van Helden's monograph, a (how shall I put it?) well-placed insider has dropped me a line...Apparently, the American Philosophical Society is planning to republish "The Invention of the Telescope" in an "augmented edition" next year (2009, the International Year ...

It may seem a little odd to be reviewing a 31-year-old monograph, but stick with it, you'll see where I'm going soon enough...The whole sequence starts with the review I posted here of Eileen Reeves' brand new "Galileo's Glassworks: The Telescope and the Mirror" (2008, Harvard University Press). Though overall very fascinating, one aspect of this ...

Back to the non-fiction grindstone, and next up on my list to read was the very promising-looking "Galileo's Glassworks", by Eileen Reeves: though this has as its main focus the issue of what Galileo knew (and when) about the Dutch telescope, I was told (by Peter Abrahams on HASTRO-L) that it also covers the pre-history of the telescope, which ...
