A later, more comprehensive analysis found that there was insufficient mercury in Brahe's system to cause death: https://newsfeed.time.com/2012/11/17/was-tycho-brahe-poisone... They also didn't find

Explosive circuit breakers are standard in electric car safety systems (in case the regular one fails). I can't imagine anyone using them in normal operation though. The space pen story is made up as well: https://www.snopes

The "war of the currents" was between Edison and Westinghouse. Tesla worked for both of them, but had very little influence on this issue. In the 19th century, using AC power was necessary because transformers were the only way to

AC is quite a lot more dangerous than DC for humans at ~hundreds of Volts. ElectroBOOM has made a nice demonstration of this: https://www.youtube.com/watch?v=snk3C4m44SY

The article was published in the journal "Gene Therapy" which belongs to the Nature publishing group, but is far less prestigious than Nature.

This is great. Noise pollution really is a massive blind spot in vehicle regulations. Even combustion-powered cars can be made pretty quiet, but morons associate "loud" with "fast", so manufacturers keep installing defea

Nature has had a news section since 1869 [1]. There are many things to criticise about them, but the science journalism is not one of them. [1] https://www.nature.com/nature/volumes/1/issues/2#News

I accept the credibility of the article because it is very well written (far above any twitter thread on the issue that I have seen), and it cites high-quality sources. In my experience, the news section of nature contains some of the best

The paper with the falsified data is from an american team and has absolutely nothing to do with LK-99.

Sunlight has tons of blue light in it (color temperature of around 5800 K). We are going to be fine.

Increasing the number of qubits doesn't help unless the gate fidelities and coherence times also improve. Otherwise, the system quickly becomes a very expensive random number generator. In transmon qubit systems, I haven't seen mu

My current favorite cargo cult is the quantum computing scene. No practical quantum computer exists, and nobody has a realistic concept for building one. Yet, there are dozens of startups and research groups developing quantum algorithms, q

The TGV averages ~280 km/h on several long-distance routes in France. For example, Paris-Strasbourg (490 km) takes 1:45.

You misread the source. The average is for the entire planet , parts of which are covered by clouds, and half of which is at night. 1 kW/m^2 is a typical value for peak insolations outside extreme latitudes. If the atmosphere absorbed

Both values refer to the quantum computer. A classical simulation would be many orders of magnitude faster.

The headline of the article is grossly misleading and has no relation to the paper it is based on. They modeled an extremely simplified toy molecule that doesn't occur in nature (a chain of four hydrogen atoms). Their quantum computer

None of the things you listed are limited by the conductors in them. The efficiency of high voltage AC power lines is limited by capacitive coupling to ground. Battery charging is limited by the cell chemistry. CPU heat output is limited

by fsh 3y ago
The current is limited by what the battery chemistry can take, not by the cables. This is why the first 80% can be charged quite fast in modern EVs, and the last 20% are really slow.

I can only read the abstract, but this doesn't look very solid at all. It's a self-reported non-randomized study, and an absurdly large number of participants has had some type of skin cancer (184 out of 276). This makes the resul

That's just cherry picking individual data points. Have a look at the time series: https://en.m.wikipedia.org/wiki/Electricity_sector_in_German... Sure, Russia's attack on Ukraine lead to an increase in 2022.

No, they haven't. Please take a few minutes to Google for the figures before making such an incorrect statement.

Indeed this is what happened according to the chats. Check for example the posts on April 3rd. This whole conspiracy theory relies on selective omission of context from the messages (I refuse to believe that Silver, Chan and co. are doing i

Could you list the exact messages (and their timestamps) where the authors are saying this in their private communications? Anything cited in the articles is very unconvincing to me.

From what I've read, their work on novel bat coronaviruses mainly consisted of sequencing samples, since culturing the viruses in the lab is notoriously hard. How are you going to infect yourself with a tiny, denatured sample used for
