Scientists have discovered a geometric shape at the center of reality, whose form defines the behavior of particles.  It's a lot simpler than trying to calculate by hand the way those things move.  It goes from hundreds of pages of math to one. 

Meanwhile I'm laughing my ass off because, well, om mani padme hum.  Not the sound of the chant, but it's literal meaning: the jewel in the heart of the lotus.  Mystical people have been staring at this thing forever, because A) it's inspiring, B) it's really pretty, and C) when you're out of your body on a lot of other dimensions it tends to be right in front of your face and kind of hard to ignore.  Which is okay because A and B.  :D  Anyhow, quantum mechanics might like to take a look at the prismatic branch of sacred art.  Perhaps it will prove inspiring.  Because quantum physics is where magic and science meet, which is why it's cool.  I may not be able to hack the math, but quantum physics still makes my existential intelligence sit up and go squee.

On the downside, this means people are getting reeeeeaaaalllly close to figuring out graviton technology.  This is about as relaxing as realizing that the toddler has just about figured out how to turn on the blowtorch.  O_O

https://physics.stackexchange.com/questions/77730/what-is-the-actual-significance-of-the-amplituhedron -- it has a link to a talk given in 2013.

These things rarely live up to the hype they generate in the popular press; I haven't heard much about E8 recently, and I'm still waiting for the atomic-powered car I saw in "Popular Science" sometime in the '50s.

Flying cars aren't a bad idea. Letting *anyone* behind the controls of several thousand pounds of *anything* when they aren't clear-headed and well-trained and focussed on safety (instead of their gorram yellphone) is a Bad Idea and Not Recommended, no matter what their altitude is.

And somebody's gonna say "just automate it." NO. This makes non-professionals *complacent*, and WHEN (not if) things gang aft agley, it'll be all over before they can hit "manual override"... ass-u-me-ing there *is* such a thing (not no way, not no how, without one...)

(Automatic buses, in their own travel lanes and walled off from everything else? Been doing it alreddie for decades. Perfectly fine. In the general purpose lanes? Fuggeddabowdit!)

Actually, what I forsee is a turf war between Detroit and the FAA, and the FAA winning and saying you're not fucking invading my safe airspace with untrained, inattentive pilots. That's what they're doing with drones... you have to have a *commercial* drone license to go above 400' AGL or anyplace remotely special...

And I agree with you about the automated vehicles with people in'em. The lawyers will have a field day, and it'll be a good fifty to a hundred years before we have automated local transport.

HA! Now that IS funny. And really quite cool.

And hey! they might figure out how to make the math easy at this rate! That would be cool. I could finally get my EE degree.

Oh cooooooool.

It may not be an understanding of gravity just yet, but challenging two of the base assumptions of physics is a pretty neat thing to do regardless.

Well, they were saying that a similar gem used to simplify the math about gravity would need to be a related, but not an identical, construct. \o/

... for a while, I had a necklace that was an LED encased in clear resin, which had been poured into a cube so that it sparkled and threw rainbows when the LED was on. I saw the illustration of the amplituhedron and thought it would make a /really cool/ version of that necklace.

Hm. It's breaking the rules, and would require a lot of handwork, but it'd be cool to have a bead representing science, a bead representing magic, the amplituhedron as the guru bead; and the remainder shifting slowly between the science and magic ones, so that the changes aren't too obvious from bead to bead, but only once you've run the whole mala. (This falls under: things I don't have the skills to do.)

Thanks for the link. The amplitude thingy diagram reminded me of fractals. It also made me dizzy to think about, which I guess is the reason for meditation ... finding out that what you think is solid really is not and being okay with that.
