As the pandemic gained momentum, emails flew among the leaders of the National Association of Geoscience Teachers. Many U.S. geology majors must take a “capstone” field course to graduate. The cancellation of more than three-quarters of these courses jeopardized graduation for many majors. So the association invited instructors to develop learning objectives that did not depend on students doing fieldwork. It also compiled online exercises to help the 29 field courses that have moved online this summer. Lessons range from “Orienteering in Minecraft” to “Geology of Yosemite Valley,” which includes a 43-stop Google Earth tour with photos and embedded text. … [Read more...] about During the pandemic, students do field and lab work without leaving home

“Even if there is a speculative element [with traditional commodities], at the end of the day you expect the price to have a gravitational pull towards the true value," Angel added. "We have models for valuing stocks and bonds, so we can get a sense of what it’s worth. But I really have no way of figuring out what a bitcoin is worth. Sure, I can go to exchanges and see what the current price is, but how do I know that that price tells me anything? If I look at the price of the euro, I know what I can buy with euros. I know how many euros it takes to get a Big Mac in Paris or a hotel room in Frankfurt.

We don’t have that with bitcoin.” … [Read more...] about Crazy currency: The more I report on Bitcoin, the weirder it gets
But despite everything we are bad at, we are getting better at holding people in the film industry accountable for specific acts of misogyny that make it harder for women to succeed. Maureen O’Dowd’s survey of 100 women in Hollywood gave voice to dozens of their specific and vivid grievances; studio bosses who say they can’t find women capable of directing a blockbuster are refuted online almost daily; actresses who speak up about equal pay are encouraged by an eager public on social media even while they’re maligned by their co-stars. Casey Affleck is getting a pass in mainstream media, but not on the internet more broadly, which continues to look at the big picture, resisting the urge to shrug off anything outside the packaged narrative his publicists want us to hear. If we really want to make sure there are no more Casey Afflecks, that’s what we need to do as well. … [Read more...] about What if the internet could make Casey Affleck the last Casey Affleck?
The first 2020 OLED models are scheduled to arrive this month with more becoming available through June. Here's where I remind you that if you want a good bargain, now is not the best time to buy a 2020 TV. New models just started coming out, prices are at their highest and they'll fall throughout the year until November (aka Black Friday time). The 65-inch B9 went down from $2,300 to $1,800 last year and there's no reason to expect the 2020 version -- which starts at the same price -- won't follow the same pattern. … [Read more...] about LG’s 2020 OLED TVs ship soon, start at $1,500 and go up to $30,000
