Any democracy I know (including the US) has used censorship in times of crisis throughout its history. There is little indication that the "slippery slope" is more than a fallacy.

This is a straw man argument. Nobody proposes shutting down essential parts of the economy, such as food production or basic infrastructure. I think we are going to survive just fine without new iPhones or SV startups for a few weeks.

The data from China almost perfectly follows a logistic curve. Unfortunately, extrapolating such a smooth function is pretty much impossible before it starts saturating anyway.

The city probably didn't plan that someone puts a hotel in the middle of a residential area. This is exactly why airbnb hosts tend to get into legal trouble in some countries.

Betavoltaic cells get outperformed by coin cells and RTGs by solar panels in most applications. There are some niche space applications, but not much else.

For neural networks to work, the activation function has to be nonlinear and monotonic. In order to be able to apply the chain rule for training the weights by backpropagation, the function also has to be differentiable. The logistic functi

I'm inclined to take the word of a famous pilot and safety expert who replicated the accidents in a simulator over that of an engineer who probably didn't. My guess is that the failure of one of the AOA sensors triggered all kinds

The MCAS failure didn't appear as a runaway stabilizer problem to the pilots. Here's what Chesley Sullenberger writes about the experience ( http://www.sullysullenberger.com/my-letter-to-the-editor-of-... ): I know

The Planck length is simply the characteristic length scale for processes where both general relativity and quantum mechanics play a role at the same time. Since these theories are incompatible, our current understanding of physics does not

I just don't get why you would want to use a quantum computer to generate random numbers. Hardware-RNGs are cheap and have existed for decades. Your CPU probably has one built-in. Some even rely on quantum effects such as shot noise, b

There is no indication (not even from the theory side) that the D-Wave approach can achieve any speed-up over a classical computer. This is one of the reasons why Aaronson and many others in the field are not taking them seriously. Sure, th

It's a marketing problem. Shor's algorithm seems to be extremely hard to run without cheating by "optimizing" the program on a classical computer that already knows the answer. Nobody wants to announce that they barely m

This makes it completely pointless to even have a high-dpi screen. I think it is a pretty common use-case to have a new 4K monitor together with older FHD ones, or a high-dpi laptop with a low-dpi external screen. X really shows its age in

Legacy applications are somewhat blurry when moved from high-dpi to low-dpi, but anything modern works perfectly well. In my experience, X with current gnome or KDE is completely unusable in the same scenario. Either everything is huge on t

It works if you have more or less the same pixel density across all screens. As soon as you mix very different ones, X becomes essentially unusable. Microsoft and Apple have solved that issue years ago.

Factoring large numbers is by far the most famous "specific use case" for quantum computers. Even in theory, they can't achieve exponential speed up (only quadratic) for travelling salesman.

This isn't about understanding the story, it's about whether you believe what Apple is saying. Is there any proof that the original secret throttling mechanism actually analyzed battery health and wasn't just a timer?

Agreed, voting by mail shares a lot of fundamental problems with online voting. Most countries in Europe have no problems at all organizing fair in-person elections.

Most quantum optics experiments are done by simply attenuating laser pulses until they have on average much less than one photon per pulse. This way the probability of having more than one photon is very low (at the cost of reduced count ra

As others have pointed out, Tesla actually spends quite a bit of money on advertising. They also got reprimanded in Germany for lying about pricing in their ads: https://www.bloomberg.com/news/articles/2019-03-06&#

Tidal forces are much too weak to capture planets. In practice, yoy always need three bodies.

What a terrible article. Not a single piece of information about actual technology. Almost reads like someone fed a Markov chain generator with content from the websites of a few bullshit blockchain startups.

Diffraction of light was only understood in the mid 19th century. They simply had no idea what to look for. In Galilei's time, making optical instruments was mostly based on trial and error.

Is there a single piece of evidence for arson in this case? I don't see any in the wiki article. House fires happen a lot. According to the NFPA, in the US there were on average around 350000 house fires per year between 2013 and 2017,

All data was typed in by hand, and the entire dataset fit into a few boxes. Resources were never an issue, so why optimize for them?

No, there is nothing quantum about the sometimes counterintuitive behavior of polarized light. It is actually pretty difficult to directly observe the particle nature of light.

Bohmian mechanics is very obscure. It is explicitly non-relativistic (unlike the universe we live in), and sometimes predics very weird trajectories: https://www.degruyter.com/view/j/zna.1992.47.issue-12/zna-1
