Imagine a dangerous road curve. Do you blame the drivers and call it a day? After all, not everyone crashes over the edge or into oncoming traffic.
Or do you bank the turn, calculate a safe speed limit and add a railing?
It won’t stop all crashes, but it’ll reduce them.
Re-engineering the road doesn’t ignore the driver’s decisions, but it acknowledges that they don’t happen in isolation. Change the circumstances, and you change how many drivers crash and burn.
Two solar ice halos spotted at lunch today.
The 22° halo around the sun is really bright and clear, and not that uncommon even in Los Angeles. I’ve seen so many that I still take photos, but I often forget to post them unless there’s something unusual about the view.
The circumhorizon arc below it, on the other hand, I’ve only seen a few times, usually fragments. It’s faint, but it’s the longest and least wispy of these arcs that I’ve seen (though the best was probably this one from 2010).
The lower one could be an infralateral arc. It wasn’t quite long enough to tell in person whether it curved upward or was parallel to the horizon, and it’s hard to tell how much of the curve in the photo is due to lens distortion. But according to Atmospheric Optics, they’re a lot rarer than circumhorizon arcs.
It’s cool to be able to get pictures of these with my phone. There was a time I’d run to get a camera and hope it wouldn’t fade first.
Saturation enhanced. It was really hazy!
I was looking for sandals and found these. They’re flip flops with a built in bottle opener, I suppose to make them more…cool? Gadget-y? But it’s on the sole of the shoe.
Someone really didn’t think this design through.
Update: There are some replies at Wandering Shop from people who’ve worn or used these. Apparently there’s another variation with a built-in flash.
GPS navigation options we need:
- I know how to get to the freeway from home.
- I know how to get home from the freeway.
- Don’t send me down someone else’s narrow residential streets just to save two minutes.
If I’m trying to get somewhere other than home after work, I’ll use GPS to get an idea of the time remaining and the fastest route. Since I’d rather avoid the freeway during rush hour, it keeps trying to send me on these zigzag paths through residential neighborhoods to avoid backed-up arteries or just avoid busy intersections. I used to follow those routes, but after a while I started noticing other cars ahead of me that were clearly doing the same thing. It’s not just one car being added to that lumpy narrow road with lots of driveways, stop signs, kids on bikes and people taking out the trash. It’s a lot of cars. And of course we’re following the same apps drawing from the same data, so we’re all taking the same side streets, not spread out among all of them.
If there’s a big difference, that’s one thing, but for two or three minutes? What’s the point?
Of course the avigation app seems so testy when I decline to be part of the problem, and it has to keep recalculating…
“I would have done the same” should never be the end of your thought process, but the start of it.
- Why would you have done the same?
- Would you have been right or wrong?
- What knowledge or differences would have changed your actions or their rightness/wrongness?
