I disagree. The human brain is difficult to understand due to the extreme complexity. Quantum mechanics is weird even for simple arrangements of a few building blocks such as the double-slit experiment or Bell tests.
Exciting results. The electron's magnetic moment is probably the most precise standard model prediction, and Gabrielse's group has measured it with 13 digits of accuracy. The positron is predicted to have exactly the same magnetic moment, but this has not been measured since 1987. With the new trap, they should be able to finally match the electron's precision.
The lack of clear evidence for manipulation in Estonia is not a strong argument to introduce it in a more high-value target. Switzerland has been "trialing" e-voting for decades with very limited success.
There is plenty of doubt about the Estonian voting system [1]. It would be an extremely bad idea to use it in a country with more international influence.
They measured the stability by comparing the nuclear clocks with more stable conventional atomic clocks. In Vienna, they used a commercial single-ion optical clock [1], and in Beijing they used a hydrogen maser (a type of microwave atomic clocks) that was calibrated to the International Atomic Time scale via GNSS satellites.
Banning teams like Ferrari or Mercedes from competing with their own cars (including the engines) would be the end of F1. The current regulations are extremely ambitious such that constructors can get a significant advantage from developing better tech. And it's working, the Mercedes powertrain is clearly dominating, even though the Ford V8 is more powerful.
F1 is a constructors championship, and the constructors are interested in developing electric power trains. Nobody wants to spend 100 million to tweak the last 0.1% performance out of a turbo-charged V8.
2.6% natural abundance is more than enough to load an ion trap. Photoionization is so selective that one can load 46Ca from a sample with natural abundance (0.004%).
I would be very surprised if any of the frontier models wasn't trained on all public physics benchmarks. Training data providers have been hiring people for exactly this task.
Electrical engineers in the 1940s already had "infinitely stable" memory in the form of delay lines and Williams tubes. Quantum error correction is incomparably more difficult than using digital bits.
Some cute tech projects do not justify a massive monopoly. Google is financing Waymo using the ~300 billion dollar it extracts annually from consumers via ad spending. I would rather pay substantially less on anything I buy, and have the free market sort out self-driving cars.
Shops used to curate their catalogs by in-house testing products from various suppliers. If a supplier comes up with a better toaster, they can send samples to the most relevant shops and convince them to stock it.
Doubles are precise to 1E-16, and the most precisely known fundamental constants have uncertainties on the 1E-12 level. This does not give a comfortable headroom, so the CODATA adjustment that determines the constants from measurements uses quadruple-precision numbers in FORTRAN.
That's not true. Digital movie cameras have a few stops more dynamic range than any analog film or the human eye. Of course this doesn't really matter since analog projectors are astronomically worse than digital on that front. This shouldn't be too surprising considering that they are literally shining a lamp though a piece of plastic.
IMHO, the only reasons for using 70 mm IMAX are nostalgia and marketing. Digital movie cameras have far better color reproduction, more dynamic range, zero frame jitter, and plenty of resolution without grain. They are also small and silent which allows far more interesting shots than what is possible with a 70 mm monster. Kubrick and Lean used 70 mm because it was the best technology available at the time. Today, the best technology is digital.
