Via Andrew Sullivan's essay today in New York, Brookings released a poll this week that shows disturbing trends among college students' attitudes about free speech: [A]mong many current college students there is a significant divergence between the actual and perceived scope of First Amendment freedoms. More specifically, with respect to the questions explored above, many students have an overly narrow view of the extent of freedom of expression. For example, a very significant percentage of students...

Via AVWeb, a company in Seattle is making an old kind of drone: Two brothers in Seattle, working as Egan Airships, have built a drone that combines features from both fixed-wing aircraft and blimps to create an aircraft that can hover, take off and land vertically, and fly at up to 40 mph. The 28-foot-long aircraft weighs less than 55 pounds and uses a patented streamlined envelope design, rotational wings and an extended tail. It’s powered on both the wings and the tail. The inflated portion of the...

Two photos from Caribbean islands that will probably never look this way again. Sandy Ground, St. Martin, February 2009: Playa Negra, Vieques, Puerto Rico, November 2016: I hope they can rebuild quickly.

It can get warm in Chicago in September, but not usually this warm. The forecast today calls for 34°C with a dewpoint above 21°C, the epitome of the worst July weather we get here. The culprits are the tropical systems currently destroying islands in the Atlantic. A dome of unseasonably warm air has stalled over the eastern US and Canada, because Jose and Maria are dumping energy into the air right off shore. So, today's temperatures will be 12°C above normal and will likely surpass the record 33°C set...

The Système International d'unités, also known as the Metric System, is the most widely-used system of measuring things in the known universe. Of the 7.57 billion people in the world, somewhere around 7.2 billion use SI. The laggards are almost all here in the United States. Sarah Kaplan, writing for the Washington Post Science Alert today, blames English privateers: In 1793, botanist and aristocrat Joseph Dombey set sail from Paris with two standards for the new "metric system": a rod that measured...

Hurricane Maria's eye passed directly over Vieques earlier this morning and has now struck Puerto Rico proper: Hurricane Maria roared ashore Wednesday as the strongest storm to strike Puerto Rico in more than 80 years, knocking out power to nearly the entire island and leaving frightened people huddled in buildings hoping to ride out withstand powerhouse winds that have already left death and devastation across the Caribbean. The storm first slammed the coast near Yabucoa at 6:15 a.m. as a Category 4...

This hurricane season may not break records for numbers or aggregate storm severity, but it will probably do so for destruction and cost. With St Martin and Barbuda all but destroyed, it looks like Vieques and Culebra are next: Hurricane Maria went through an astonishingly quick transformation from a minimal hurricane to a Category 5 monster in less than 24 hours. As of 9 p.m. ET [Monday], Maria had maximum sustained winds of 250 km/h, and the island of Dominica was right in the path of the worst of the...
