The comparison doesn't make any sense. Here is the IAEA report that lists the stockpile as reported by Iran (page 8): https://www.iaea.org/sites/default/files/25/06/gov2025-24.pd...

That's the problem. Building a heavier rocket is much harder than building a lighter one (see explosion above). So why not send a few lighter ones instead of a heavy one? This is what the launch market has concluded for a long time.

Sure, the Saturn V and STS were much less safe than smaller rockets. Still, they blew up an awful lot less than other rockets of their size like N1 or Starship.

The problems with Starship make the Saturn V and STS programs even more impressive. However, I still don't get the rationale of building a rocket with such a large payload. The rocket equation will always force you to build an absolute

The accuracy of atomic clocks is much better than our understanding of fundamental physics. The best calculable atomic system is atomic hydrogen, and state-of-the-art quantum electrodynamics calculations reach a relative accuracy of around

The modules physically won't fit. American optical tables have screw holes with 1 inch spacing and some imperial thread, whereas the rest of the world has 25 mm spacing with M6 threads. Having to manually fiddle with the pattern sort o

Great idea, but the hard-coded imperial units make this very difficult to use for most of the world. Also the plugin still appears to be extremely buggy and unfinished.

Transformer LLMs are good at generating text since they were trained on huge volumes of high quality texts. There is no reason to assume that feeding a neural net with unlabeled garbage data (i.e. video recordings from random cars) is goi

Each antiproton annihilation releases 0.3 nJ. So for ~100 antiprotons, one would get 30 nJ which is equivalent to 7 picograms of TNT.

This is incorrect. The only measurement of antimatter gravity so far by ALPHA-g resulted in no difference to normal matter within the experimental uncertainty [1]. This is not surprising, since any difference would violate conservation of e

The fork is in the play store and works fine for me on Android 15: https://play.google.com/store/apps/details?id=com.github.cat... I was a bit surprised that the official client suddenly disappeared though.

The vast majority of people are paying separately for all kinds of stuff. I don't see a reason why software and digital services have to be different. In the early days, payment was difficult, but this has been long solved. I am convin

This list is very telling. Instead of a healthy marketplace of companies competing to sell their software and services, we end up with one monopolist who gives away mediocre products and in return taxes everything you buy (in the form of ad

Both Gnome and KDE handle (un-)plugging external monitors just fine. And Wayland has been the standard in all relevant desktop distributions for a couple of years now.

I disagree. LaTeX is very good at layouting test, and can also (reluctantly) put figures into the text. Anything else is a huge hack (like TikZ), and one constantly runs into crazy limitations such as the fixed-point math and the lack of a

Please nobody actually do this. Good presentation slides have almost zero overlap with the corresponding article since they serve completely different purposes. In my field, seeing beamer slides is a huge red flag for an imminent terrible p

A $5 GPS receiver runs circles around a CSAC, so the range of useful applications is quite limited.

I don't see why. Battery-backed renewables should be much easier to synchronize than spinning generators.

Solar shingles are available from a variety of companies. However, the market success appears to be quite limited. Not too many people are willing to pay a considerable premium for a slight cosmetic advantage.

This problem has been solved more than a decade ago by radar sensors (standard on many mid-range cars at the time). They detect imminent collisions with almost perfect accuracy and very little false positives. Having better sensor data is a

Indeed, the business model of selling a worse and much more expensive version of something that everybody already has [1] is a bit questionable. [1] https://en.wikipedia.org/wiki/RDRAND

It would be interesting to compare the accident statistics with European climbing gyms where belay tests are not common. The coach in the video has some of the worst belay technique I have ever seen. Unfortunately, this is somewhat common a

QKD also needs key distribution to prevent MITM attacks. It behaves almost exactly like a classical stream cypher, except that it cannot be package-routed, is many orders of magnitude slower, and is prone to side-channel attacks.

For most users (me included), there is zero difference in user experience between using wifi or Ethernet for their TV. Otherwise, running wired Ethernet would probably be a lot more popular.

The problem with selling inferior technologies is that sooner or later people are going to stop using them (even in the Grad Basin region). Not exactly a recipe for success.

Yes, they use superposition of the most "classical" quantum states (coherent states). These are called (Schrödinger) cat states, since his thought experiment was about a quantum superposition of a very classical object (a cat): h
