New from me. Mark Carney’s Oprah giveaway day, and a vexing question: if a new pipeline is a money-printing machine, why does no private company want to build it so that taxpayers have to? #cdnpoli www.theglobeandmail.com/politics/opi...

After about 5 years (!) of keeping secrets, I am so excited that Disney Pixar's Hoppers is finally coming out on March 6th! Back in 2021, Pixar emailed me asking if I could give a talk about my research to their employees. Then another talk. And another. 📸 Disney/Jesse Grant/Getty Images

Stopped the bike ride for a little geology. Fascinating mud cracks that peel off in layers, and sticky clay underneath. Little minds shocked and amazed when they learned that mud cracks are found as 'fossils' too. #geology

Fire-induced rock spalling! This area burnt about 1-2 months ago. All of the little rock shards on the ground are spalled pieces of the granite boulder, overlying burnt soil and moss. Before seeing this in person, I didn't really consider the mechanical weathering effects of fire!
