Preventing Sick Spaceships
May 12, 2000
Picture this: You’re one of several astronauts homeward bound after a three-year mission to Mars. Halfway back from the Red Planet, your spacecraft starts suffering intermittent electrical outages. So you remove a little-used service panel to check some wiring.
To your unbelieving eyes, floating in midair in the microgravity near the wiring is a shivering, shimmering globule of dirty water … Read the rest of this article
My Forays Into Astrophotography
March 28, 2000
I’ve been interested in astrophotography for a number of years and dabbled with it on and off, taking the ubiquitous star trail type images and also using a barn door mount for taking longer exposures.
It was only after I bought a telescope that I became any way serious about astrophotography. Below you’ll find a number of photos I’ve taken … Read the rest of this article
The Forgotten Astronomers
September 13, 1999
By Tim Carr
Even those people who know nothing about astronomy (and there are plenty of them, it would appear) have heard of Galileo and how he changed our view of
the heavens.
They’ve probably heard of Copernicus, Newton and his apple and maybe even Kepler, the codifier of the laws of planetary motion. But just how many of them … Read the rest of this article
Forgotten Astronomers – Rene Descartes
August 22, 1999
By Tim Carr
If Nicholas of Cusa and Ulugh-Beg weren’t famous then this man certainly was, and still is. The “father of modern philosophy” and brilliant mathematician has an honoured place in European history but what you might not know is that he also tried to reconcile the church and the Copernicans as to which world-view was correct.
In 1612, … Read the rest of this article

Book review by Tim Carr
Isaac Newton: The Last Sorcerer
By Michael White
| [ReviewAZON asin=”073820143X” display=”inlinepost”] |
Like most people my view of Isaac Newton was the traditional one. Lonely recluse who single handedly changed our view of the universe in the most profound way – liked by few, admired by many.
Michael White’s long book doesn’t contradict any of this, … Read the rest of this article
Forgotten Astronomers – Ulugh Beg
July 17, 1999
By Tim Carr
The great Mongol empire was not noted for its scientific achievements and with good reason. But in 1428 Tamerlanes’ grandson Muhammed Targai Ulugh-Beg, who was governor in part of central Asia, established an astronomical observatory at Samarkand.
As the telescope was still centuries away, astronomers had to content themselves with naked-eye observation. He published a … Read the rest of this article
Forgotten Astronomers – Nicholas of Cusa
July 1, 1999
By Tim Carr
You might think that anyone who published a book in 15th century Europe, saying that the Earth was just another world orbiting the sun rather than the centre of the universe, might run foul of the catholic church very quickly. That is just what the German cardinal Nicholas Krebs did in 1440 more than a century before … Read the rest of this article
