By far my favorite feature of matplotlib is that it produces readable and accessible plots by default. Font sizes and linewidths are not too small, the default color palette is colorblind-friendly, and the default colormaps are perceptually

The article says that "[...] the blotch is unquestionably more noticeable on the black frame". It also looks more noticeable to me on the picture.

I love how they wrote an entire article fawning about how awesome this process is before showing that it doesn't actually work at resisting fingerprints. Apple's reality distortion field at work.

Qalculate! has an RPN mode. As a research scientist, this is my default calculator (not in RPN mode though).

That part is pretty clear. People are eating more calories than they did in 1970. The more difficult question is: why are they doing that?

AFAIK, the EU has made open access publication of ERC-funded work mandatory. Maybe the authors haven't gotten around to put the manuscript on the arXiv yet.

No, they really didn't last decades. The horrible two-stroke engine of the Trabant had a design lifespan of only 60000 km, and the rest wasn't much better. Since buying a new car was nearly impossible, people kept theirs on the ro

I think you got this backwards. Tesla made a few important inventions early on and then spent the rest of his life showing off big sparks and scamming investors. Edison's labs were far more influential.

You're right, it seems like this is exclusive to the EuroCity between Munich and Zürich which is a cooperation of DB, SBB, and ÖBB.

The Swiss trip planner now completely ignores DB trains for trips within Switzerland. They don't want to disappoint their customers.

The reliability of German long-distance trains is objectively bad (and getting worse). Here are the official statistics: https://www.deutschebahn.com/de/konzern/konzernprofil/zahlen... The middle tab ("D

I don't see how patents on trivial stuff like synchronized playback are supposed to help startups. The big corporations are sitting on enormous piles of those which makes entering their markets extremely risky.

It's different because they are using a gas as an acousto-optic medium. This allowed them to work with laser intensities that are more than three orders of magnitude above the damage threshold of conventional solid-state acousto-optic

From the article: "However, I have already bought this product and the other pieces for my car mount." The black ring is probably one of the "other pieces for my car mount".

Using too large input filtering capacitors without a soft-start circuit is a sign of very poor circuit design.

Betavotaic generators usually produce extremely low power. A similarly sized battery can last for decades at the same power output.

There are betavoltaic generators [1] that directly produce electricity from decay electrons using p-n junctions (similar to photovoltaic cells). However, in the vast majority of applications, they get outperformed by modern lithium batterie

Grass has an albedo of around ~0.2 which means that it converts ~80% of the incident sunlight into heat. Solar panels are pretty black and have efficiencies of ~20% which means that they convert ~80% of the incident sunlight into heat. The

Lithography requires the highest possible average intensity, while the pulse length is irrelevant. The laser-driven tin plasma sources used in EUV lithography produce around 7 orders of magnitude more power than the most powerful sources ba

I really like Hossenfelder's physics videos. However, once she leaves her area of expertise, the quality drops off a cliff. Most of these videos are just summaries of random articles with no critical thought.

The recollections of an 88 year old person about an event 60 years ago are simply not credible. He may truly remember picking up the bullet, but that doesn't mean it actually happened. Since he didn't mention it in his memos at th

Protons and electrons do not decay according to the Standard Model.

No, it isn't. According to the Standard Model, the proton is stable at every time scale. And no proton decay has ever been observed.

There are nuclides heavier than 56Fe, for which no decay mode is energetically allowed. 197Au is not one of them, because it could in principle do alpha decay. Wikipedia has a long list of theoretically stable nuclides (no decay mode possib
