"15 years" seems like an oddly specific number?

But invention of gravity-wave detectors (laser interferometers) have been the most exciting thing and can't wait for them to build the space version, so maybe go for it?

Won't be funded in US this decade though, they are even cancelling space-telescopes ready to launch, sigh

Odd but related question if anyone knows:

Are all preprints on arXiv public?

Or is there actually a private unlisted preprint queue?

From behavior I've observed, I'm guessing maybe authors have the ability to hide papers and send private invites for select peer-review?

> I'm guessing maybe authors have the ability to hide papers

No they do not.

In fact, authors cannot even delete submitted papers after they have officially appeared in the (approximately) daily cycle. You can update your paper with a new version (which happens frequently) or mark it as withdrawn (which happens rarely). But in either case all the old versions remain available.

Papers can be held my moderators, but as an author when you post you don't have the ability to hold or hide your paper.

Postings go up once a day as a batch, so you could wait 24ish hours to see your paper appear, longer if your posting is just before the weekend.

That backdoor code is going to lurk for decades.

Not only will Musk be able to tap into it for years but foreign governments.

This is the real problem, and the reason we never should have allowed access to sensitive government and societal data in this fashion.

Wikipedia has this amazing chart of progress since 1975

(ignore the purple line which isn't cells)

But maybe cost reduction is a more important record even if it stalled at 20-25%

I was thinking this morning how weird it is that everyone knows who Einstein was

But much smaller percent Niels Bohr

Congress could end this in 24 hours with a one paragraph/page bill

and regardless who is in power next decade the dems should anyway

It's like some blackhat is trying to find every loophole in government and exploiting it, like a fuzzer test

Mid term elections are November next year. Some time between now and then, republican house and senator members will start getting more than a little bit anxious about not losing their seats. The current chaos is not great for their chances. The closer that election gets, the more likely it is that something like what you suggest might happen.

The problem of course is that any move like that is going to result in chaos inside the republican party. I imagine that might delay the moment before e.g. Mike Johnson (speaker of the house) puts such a thing up for vote in the house. Because it sounds like that would be a career ending move for him. Until that changes, Trump can do as he pleases essentially unopposed.

The democrats has the president for 4 years, and plenty of power in congress. If they cared they would have done something.

I was going to link the excellent solereview article but it looks like that's exactly what the post is about.

I used to be able to buy good running shoes on clearance every year at $30-$50

Even through 2020-2021 or so

But not anymore, now even on "clearance" they almost never drop below $100 and never ever to $50

Actually no, coal is still going to die in the US unless China sells us their coal for dirt cheap.

You get more watts per human labor hour with our abundant natural gas reserves. No matter how cheap you drive labor, it will still be more economical to use that labor to drill wells.

Coal was always dying, especially in the US, because of economic concerns. It's a stupid source of energy.

The fact that anyone in the US even thinks of coal is absurd. There are maybe 60k coal miners in the US. It hasn't mattered in decades.

Aren't there stock electric cars now that do quarter mile under 10 seconds?

When battery weight gets cut in half next decade and capacity doubles, the only reason why they will race ICE engines is for the noise

Our Hyundai grocery-getter does a 1/4 in 13s, the "N" go-fast version does it in 11s. And those are Hyundais with full-sized, heavy-ass batteries, and abysmal stock tires. Porsche Taycan GT (with a full-sized, heavy-ass battery) turns 1/4 in 9.3s.

Now cut those heavy batteries in half because you're not driving from SF to LA, and I could see that Porsche turning 8s if you could get the power to the ground (IOW, launch control and much better tires than stock).

If you want to get into electric small-batch performance cars, BYD has you: https://en.wikipedia.org/wiki/Yangwang_U9

I don't believe there's anything even remotely competitive in the electric world to Top Fuel dragsters. You could also make the same argument about F1 vs E1

https://en.wikipedia.org/wiki/Top_Fuel

> Top Fuel is a type of drag racing whose dragsters are the quickest accelerating racing cars in the world and the fastest sanctioned category of drag racing, with the fastest competitors reaching speeds of 338.94 miles per hour (545.5 km/h) and finishing the 1,000 foot (304.8 m) runs in 3.641 seconds.

AFAIK the fastest "production" EV is the McMurtry "Spéirling" that does a quarter mile in under 8 seconds. Watching it set the record for goodwood is mind blowing, because it looks like the video is being played in fast forward, but it isn't.

Although you can in theory buy one, it uses down force fans so I don't know if it would even be street legal in most places. Personally, I find car like this to be way more interesting than drag racers.

I don't know if you understand just how much of a difference there is between a 4.5 second car and a 7.5 second car- it is orders of magnitude.

Even with half weight and double capacity- the worlds fastest EV will get walked by a fast gasoline street car
