This is your state on fireworks. Air quality levels were typical for most of July 4th, but watch for the explosion of air pollution right around 9pm.

Somewhere in there there's also a map with estimated MMI values... but the site isn't really working now. (I don't even see where you see the IX.)

More curious about the max MMI, given
The Richter scale is a (logarithmic) measure of energy released, so says as much about how much area was affected and for how long as about how strong it was at any one place & time. The Modified Mercalli scale is a better measure of how bad a quake is at a particular point.

But it was 7.1 two minutes after it happened!?

... also should have mentioned duration there.

In some Republican controlled states, gerrymandering has made it all but impossible for Democrats to retake assemblies, even when they win a majority of the statewide vote. This chart sums it up: bit.ly/2YAcjWP

I have an exit row seat on a 10 hour flight on a Boeing 767 to offer you... (The window exits on the 767 are good heat conductors, so starting after about 4 hours at altitude, the exit window housing is just a massive heat sink. I rarely use blankets on airplanes, but...)

I've dealt with cases where I could identify and explain a skill somebody needed to learn (a skill that comes naturally to some people), but still couldn't figure out how to teach it.
I'd love to see studies as to which teaching methods work and which don't. I deal with later stages of the same process: CS graduates learning how to work on a software project/ecosystem with millions of lines of code & hundreds of people.

Trump administration lawyers may have sabotaged his effort to rig the Census. The lawyers wrote that they are looking for a "new rationale," after SCOTUS declared the last one a pretext. That gives away the game, a legal expert tells me. My new piece: washingtonpost.com/opinions/…

9 years ago, Europe saw more pedestrian fatalities per capita than did the US. Today, they have half as many per capita as we do stateside. In just one decade, Europe has dramatically reversed what many in the US see as just the cost of doing business. We can change it here too.
