Last week, I was in Calgary on family business, but I took an afternoon to host a 'private beta' for a short course that I am creating for geoscience computing. I invited about twelve familiar faces who would be provide gentle and constuctive feedback. In the end, thirteen geophysicists turned up, seven of whom I hadn't met before. So much for familiarity. I spent about two and half hours stepping through the basics of the Python programming language, which I consider essential material — […]
A few weeks ago I looked at the concept — or concepts — of brittleness. There turned out to be lots of ways of looking at it. We decided to call it a rock behaviour rather than a property. And we determined to look more closely at some different ways to define it. Here they are... Some brittleness indices There are lots of 'definitions' of brittleness in the literature. Several of them capture the relationship between compressive and tensile strength, σC and σT […]
Cruising around the web last weekend looking for geosciencey Christmas presents, coupled with having 3 kids (aged 9, 5, and 3) to entertain and educate, I just realized I have a long list of awesome toys to share. Well, I say toys, but these amazing things are almost in a class of their own... Bigshot camera A full kit for a child to build his or her own camera, and it's only $89. Probably best suited to those aged 7 up to about 12. Features: comes with everything you need, including a […]
It's that time again! If you're tired of giving the same old rocks to the same old geologists, I've got some fresh ideas for you. Stuff My wife came back from town recently with this spectacular soap, from Soap Rocks. I mean, just look at it. It's even better in real life. You just can't go wrong with a beautiful hammer, like this limited edition Estwing. Don't forget safety glasses! Or go miniature, with these tiny (Canadian!) hammers in gold ($859) or silver ($249). Steepish prices, […]
The new book is out! You can now order it from Amazon.com, Amazon.co.uk, Amazon in Europe, and it will be available soon from Amazon.ca and various other online bookstores. What's it about? I sent Andrew Miall some chapters at the proof stage; here's what he said: Geology is all about rocks, and rocks are all about detail and field context, and about actually being out there at that critical outcrop, right THERE, that proves our point. The new book 52 Things You Should Know About […]
