I'm very pleased to once again be participating in Ad Astra, Toronto's annual science fiction convention. I'll be giving a talk on "time" on April 10, and will also be involved in other events over the course of the day.

I profile Glendon Mellow for New Scientist's "Culture Lab" website. The Toronto artist has been deeply influenced by Darwin, evolution, and... trilobites!

I review the new IMAX movie, "Hubble 3D," for New Scientist's "Culture Lab" website. The movie features several "voyages" through the Milky Way and beyond, as well as stunning footage shot by the space shuttle astronauts themselves -- "a nice combination of astronautical derring-do and the more cerebral thrills of modern cosmology."

I review Anil Ananthaswamy's book, "The Edge of Physics," for New Scientist magazine, and for their "Culture Lab" website. Ananthaswamy travelled to some of the most remote regions on earth -- sites where scientists are investigating the most urgent problems in modern physics. He "weaves a remarkable narrative that combines fundamental physics with high adventure."

I examine the life and science of English astronomer Thomas Harriot – sometimes called "England's Galileo" – in the new (April 2010) issue of Astronomy magazine. The article, titled "Who was Thomas Harriot?", can be found on page 44 of the magazine's print edition.
