January Science Book: A Fish Caught in Time

January Science Book: A Fish Caught in Time

The Monthly Science Book that I’ve selected for January is A Fish Caught in Time: The Search for the Coelacanth by Samantha Weinberg. This book has been on my reading list for awhile, ever since I visited a little museum in Knysna, South Africa, dedicated to the Coelacanth and its discoverer. Here’s the description of the book from Amazon: The coelacanth (see-lo-canth) is no ordinary fish. Five feet long, with …

Monday Geology Picture: The Big Hole, Kimberley, South Africa

Monday Geology Picture: The Big Hole, Kimberley, South Africa

This week’s “Monday Geology Picture” is a shot of the Big Hole in Kimberley, South Africa. This hole, now filled partly with water, is the remains of an early diamond mine in a kimberlite (a rock type named after the town of Kimberley) pipe.

Introducing a New Feature: Monthly Science Book Review

Introducing a New Feature: Monthly Science Book Review

I’ve been negligent with my blogging again. I was in hospital in October and out of action for a few weeks. I’m doing much better now but had to catch-up on a few things, mostly at work! So, my blogging suffered once again. To kick-start the blog again and go in a slightly different direction, I’d like to announce a new feature: a monthly science book review. I’ve been meaning …

Monday Geology Picture: Old Maps of Africa

Earlier this year I visited a local wine farm here in the Western Cape of South Africa, and there I saw a lovely display of some reproductions of some old maps of Africa. I’m not sure about the background of these maps, but I snapped a few pictures because I thought they were interesting. If you recognize any of the maps, please let me know in the comments. Here are a …

Monday Geology Picture: Pretty Purple Stichtite

Monday Geology Picture: Pretty Purple Stichtite

For this week’s picture here’s an example of one of my favorite minerals: stichtite, a lovely purple-colored chromium and magnesium rich carbonate. I saw this particular sample of stichtite for sale at a rock shop. Stichtite comes in a range of purple shades, from a pale pinkish purple to a rich, bright purple. I really like the lilac shade of this particular sample. The R3500 (about $250 US) cost for this sample was …
