Is there any word on the toxicity of these things vs. OLEDs? I would guess that both in manufacturing, and eventual disposal, CdSe might present more of a problem than many organic semiconductors. » 1/06/15 6:21pm 1/06/15 6:21pm

"Long term weight loss almost impossible"

Just figured this might be a good forum for interesting discussion. My personal opinion is that 5% shouldn't be sold as "almost impossible", which is a stupid phrase anyway. Almost impossible things are by definition possible. » 6/04/14 6:08pm 6/04/14 6:08pm

My week has deteriorated. Climbing trip got cancelled because someone had "too much school work". Students and their damn responsibilities.... And then this morning I've made plans to meet someone for coffee at 11. Which means it's 10:25 and I have yet to have coffee. I can feel my brain shutting down. » 6/03/14 1:26pm 6/03/14 1:26pm

Then groceries and climbing and making dinner. And there's still that damn textbook I'm… » 5/29/14 11:05am 5/29/14 11:05am

The chosen research will then be the focus of the $17 million Longitude Prize announced last June by British PM David Cameron. The fields the scientists have selected are… » 5/20/14 9:15am 5/20/14 9:15am

It's a holiday in Canada today, but I'm going to work anyway because I only work 2 days a week and taking one of those days off feels like pushing it. Should be pretty relaxed though as the office will be mostly empty. There will be many coffees. » 5/19/14 11:12am 5/19/14 11:12am
