The sound will take just as much time as it always does. The difference is that the time between when the sound reaches you and the train reaches is reduced by the ratio of the (speed of sound - speed of train toward you) / speed of sound. If the train is going the speed of sound towards you, the train will arrive at…

225, 226, whatever it takes. 

Congrats to the designer of the underhood insulation. That kept the hood cool enough to keep the paint OK much longer than I expected it would. 

We had those in Missouri, well, in Saint Louis and, I expect, Kansas City. Then cars started to be required to have their own vapor recovery systems and the EPA dropped it.

Two things -

It did not help that the LAPD detectives went out of their way to plant evidence nor that the LAPD had and continues to have a reputation for being violent and racist. Some say they have changed, but it’s far from complete.

Don’t worry. Google will shut off some critical service that leaves all of these useless and non-functional in about 3 years. 

Bravo on using the timestamp. Thanks. What a disaster. 

Many places are using cameras that look at the street. They don’t require cutting the pavement, no post-cut sealing, no running underground wire. They have to be incredibly cheap in comparison. They are mounted above the traffic lights and I think they don’t typically record video or read license plates; they compare…

The problem is that many times one cannot stop 100 yards away, where it is already too bright and just wait a few hours while the police get their crap together and there may be no turn-off, though that may not work as cops have used that as an excuse for an aggressive pursuit on the grounds of avoiding them.

One way is to put on a conductive paint, then electroplate with copper to get a uniform coating and then plate over that.

With a small rocket it will make a small change to an already circular orbit, a change that won’t be enough to escape the gravity of the Earth. It takes a huge amount to remove the orbital speed that it gained simply from being launched from Earth to have an orbit to get anywhere near the Sun.

The article it links to says that the aluminum oxide particles act as an active chemical surface to make the chlorine in the atmosphere more effective at destroying ozone. It’s a direction I did not expect it to take; I assumed the aluminum oxide was the problem, not that it was an enabler to an existing one. 

Space is big. the surface area of the earth is 4*pi*r^2. At r=4000 miles, that gives 201,061,929 square miles or an average of one satellite getting 4000 square miles to itself. Avoiding them is just a matter of timing, but then all launches are a matter of timing, such as to match orbits with the International Space…

“500 times more toxic than diesel exhaust and has no known safe level of exposure.” It is also released at 1 millionth the rate, so the net population effect is microscopic.

Perhaps emergency vehicle operators could go back to not using blinding amounts of light so one could actually judge where the vehicle is and see if there is anything or anyone near it. It doesn’t take much light in the dark to see something flashing, but when the light is bright enough to read a book while still 100…

Politically, because the lobbyists don’t want it. They don’t want it because Medicare and Medicaid are two of the largest providers in the US and that would ruin the Corporate leaders and their shareholders rolling around in cash afternoons. 

It raises the question.

Sandra “Sandy” Schultz-Peters, 66, of Myrtle Beach, died of injuries sustained upon being struck by a vehicle while on the beach, according to the Horry County Coroner’s Office.

Biking on soft sand seems like a no-go, but small buggies and ATVs seem ideal for this. There are certainly parallel streets if there is a need to move stretchers and other bulky or even heavy items rapidly to respond, but patrolling with limited visibility vehicles on a beach crowded with people who might be sleeping…
