It is a misconception that digital is lossy but analog is not. In digital recording, the finite bit depth of the sampling process effectively adds a small amount of white noise to the signal (the difference between the sampled value and the

Radio waves were discovered by Hertz long before Tesla or Marconi were working in the field. When it comes to actual applications of radio, Marconi was certainly much more influential than Tesla despite him holding some early patents. It is

Radio technology has been in widespread use for over a century. The only health effects that have ever been conclusively demonstrated are due to heating of the tissue. A typical Wifi router with a few hundred mW of maximum power probably wo

In the lab we do measure things and we do observe wavefunction collapse. There is no satisfying explanation why "us becoming entangled with the quantum system" or whatever explanation one chooses looks like collapse to us.

USB-C and proprietary laptop chargers are double insulated Class II devices. This means that the metal chassis is essentially floating and can charge up if there is some leakage in the charger circuit. I don't see any way how the wirin

It's a Monte-Carlo simulation, not a statistical model. These are usually written in C++ for performance reasons.

I would argue that the Swiss system only "works" because the people reject the vast majority of referendums and let the elected parliament do the actual policy work. In total, only 22 have been successful since 1891. Most of them

Most european countries simply don't have any problems with pen and paper voting. Turnout is typically much larger than in the US with its crazy mix of electronic/mail-in/in-person voting. Probably this is due to automatic vo

That's just cherry-picking one particular case with a positive outcome. The last few Boeing CEOs were also paid tens of millions per year and ended up running the company (and two planes) into the ground.

Unless of course the developer uses yarn or whatever npm alternative is popular this week. The last time I tried building an electron app, it just spit pages of dependency errors at me and I gave up.

Indeed this is not possible for a classical wave. However, in a quantum description there exists a so-called "vacuum state" for which the expectation value of the electric field operator vanishes at all times, but the expectation

According to European surveillance data [1], diarrhea is also a very rare symptom. The authors don't have a convincing argument why this should be a good indicator for COVID-19. [1] bottom row in this picture (I couldn't find an E

I believe the choice of Chromium and JS for the UI simply shows that the astronauts are merely inconvenient payloads. Gagarin's first flight was already fully automated 59 years ago.

"Fake science" implies intent to mislead. The reproducibility crisis is usually attributed to selection bias due to only positive results getting published.

Counting qubits is not a useful metric. Google actually had to go back down from 72 to 53 in order to get their quantum supremacy experiment working. Also none of these machines are error-corrected, so they cannot run useful quantum algorit

These courses are usually short introductions into python or Java. Most scientists simply don't have time in their curriculum for a full software engineering course.

Sorry, but this is completely wrong. Analog systems, such as human ears, can be band-limited but do not have a sample rate. In fact, any digital recording system requires analog lowpass-filtering to avoid aliasing. Otherwise, the original

This is not how any of this works. Sound simply is a variation of pressure over time, hence a one-dimensional signal (in classical physics, time is not considered a dimension). Sampling is simply a way of approximating this continuous sign

D-Wave is building "Quantum Annealers" which are not universal quantum computers. They cannot run quantum algorithms such as Shor's algorithm and there is serious doubt whether they can achieve any significant speed-up over c

E=mc^2 is a consequence from special relativity, not a theoretical framework. It also has very little to do with the understand of nuclear reactions. The reason why nuclear reactions release much more energy than chemical reactions is that

Having one guy micromanage a large research group is also very inefficient. Nobody (not even Martinis) knows if and how a practical quantum computer can be built.
