5·5 hours agoCool video. Doing the double-slit experiment in my freshman physics class is a favorite memory from college. Seeing it in person blew everyone’s minds, even the kids who had learned about the experiment before.
If you google “is energy conserved in the double-slit experiment” you’ll find some physics forums with decent answers. Basically, the total energy emitted by the light source does not change. Energy is conserved. Don’t think of the laser light as a discrete beam that is being split off onto a second path. Instead, imagine that the laser light is constantly shining all over that foil and card. The dark regions appear dark because the light waves there are canceled out by interference from adjacent light waves. Similarly, the red areas are illuminated because in those areas the adjacent waves did not cancel each other out. The bright spots visible on the polarized foil occur because the polarizer blocks thin regions of the light, preventing them from canceling out adjacent light that wasn’t blocked. So light wasn’t redirected there, but was always there and was simply made visible to us by the effect of the polarizer.
Light, quantum mechanics, and the probabilistic nature of the universe are all real head trips. I still struggle to wrap my mind around them. As such, there’s a good chance my simplistic paragraph above is incorrect or misleading, so take my answer with a grain of salt.
See the other comment that I left moments ago. This isn’t AI; it’s real equipment on public display. I linked other photos of the same thing from different sources.
It’s definitely not AI. It’s on display as part of the B Reactor tour. You can find other photos of the same display. For example:

God damn, we are in the worst timeline.
I try to pick from a variety of sources, but it’s tempting to make this community nothing but toolgif reposts for a few weeks. There are so many cool things to share.

Thanks for letting me be one of today’s lucky 10,000.
Careful, that’s how that one evil boyfriend in Scott Pilgrim died.
Stuck on the treadmill of adulthood but determined to have a good time.
KEXP is doing their six-degrees week and I am loving it! Today is the last day, so y’all still have a few hours to listed to the livestream if you like.

5·6 days agoAbsolutely brilliant.
81·6 days agoIf someone has the desire and the means to drop $10k on a hobby they love then I won’t judge. Plenty of folk spend that much or more on musical instruments, or photography gear, or motorcycles, or a hundred other things.
2·6 days agoNice! I love the paint colors.

I was thinking of central heat and air conditioning accessible to the masses for home use. But you are right that the history of HVAC goes back much farther than that.
Oh, and salmon sushi was invented in the 1980’s by the Norwegian fishing industry. Before that, no salmon in sushi.
You know how you can push some buttons on your wall and your house magically warms up or cools down? I know people who were alive before that existed.

But fries with shawarma? Sign me up for that. And pile on some extra garlic, too
At this point I have to admit that I am out of my depth. We need a real physics major to chime in.
