In my experience, the High-DPI support of Windows 10 is excellent. I am using a 27" 3840x2160 screen set to 150% next to an old 24" 1920x1200 screen at 100%. Pretty much all modern applications seamlessly adapt to the pixel densit

To me it feels like these companies are trying to sell Kubernetes to a community that has not yet invented the vacuum tube (and might never manage to).

The statement you linked to says no such thing.

Without proper statistical analysis and epidemiological modelling this is nothing more than an anecdote. The last twelve months should really have taught us not to trust those.

In the EU, bank transfers (in €) have to clear within one working day. Transfers between your own accounts at one bank are typically instant. There is no fundamental reason for bank transfers to be slow. And unlike bitcoin, banks can handle

How does a spread make people lose money? Trades only happen if the buyer and seller agree on a price.

The BioNTech/Pfizer trial included 1712 people age 75 and over. The mean age in that group was 78 and the maximum 91.

Objective-collapse theory is a modification of QM, not merely an interpretation. Superdeterminism on the other hand is not even a theory. It cannot be falsified by design.

by fsh 6y ago
None of the interpretations of quantum mechanics are. By design, they all predict exactly the same outcome for any conceivable experiment. The subject is entirely philosophical, not scientific.

Anything can be turned into a product. The appeal of chip-based technologies such as superconducting qbits or integrated photonics is that one could at least in theory scale them to orders of magnitude larger sizes. This is simply not possi

Beautiful setup! On the flip side this looks extremely hard to scale. I wonder how many students were required just to align this thing.

I wouldn't be so sure. Jian-Wei Pan is known for having a pretty much unlimited budget. They launched a freaking satellite!

The BioNTech/Pfizer press release mentions a reduction in confirmed cases (8 vs. 162), not in severity. There is no good reason why such an effective vaccine should not reduce the risk of spreading the disease. However, even a large

No, mRNA is not DNA.

The new Proxmox Backup Server uses this feature for backing up VM images. In our setup this has accelerated daily backups by an order of magnitude.

Pretty much any biology lab in the world has -80 °C fridges. For shipping, a styrofoam container with some dry ice is probably good enough.

Commercial multiphysics simulators such as COMSOL are widely used in engineering and experimental physics. Of course they cannot cover all possible use cases, but they are perfectly fine for the vast majority of simulations.

I don't see anything wrong with this tweet. At the time, this was the only information available about the disease, and the source and preliminary nature of the research are clearly stated. One week later, the WHO had already conducted

No. Conservation of energy still exists in General Relativity.

The idea that people might infect themselves by handling their own masks sounds very far-fetched to me. What mechanism is supposed to do that? The risk of people neglecting other measures sounds more reasonable, but most politicians seem to

by fsh 6y ago
This is not the point I was trying to make. Of course it is important to monitor new scientific evidence that arises and to update the measures and recommendations accordingly. I believe that most functional governments are trying to do exa

The current working hypothesis seems to be that wearing a mask protects other people from getting infected by the wearer, rather than the wearer himself. Testing this hypothesis in a randomized control trial sounds extremely difficult, sinc

Nuclear fusion is pretty much the exact opposite of a low entropy source. In any case, thermal power plants (gas, coal or nuclear) reach up to 50% efficiency with modern gas or steam turbines.

Sure, the particle showers that cosmic rays create in the atmosphere contain some muons. Still the sun itself does not emit muons, and even if it did they would decay long before reaching earth (or a satellite).

by fsh 6y ago
Tens of millions of dollars were invested in trying to replicate the cold fusion experiments with zero success. That, combined with Fleischmann and Pons' general incompetence, makes it pretty obvious that the initial report was a fluke
837.
by fsh 6y ago
The sun is not a muon source. Muons have a 2 us lifetime, so even highly relativistic ones don't get very far before decaying.

It is not possible to calculate the ratio between the transition frequencies in different atoms with anywhere near sufficient accuracy for metrological applications. Therefore, only Cesium clocks can serve as primary standards for the SI se

Laser cooling only reduces the velocity component that is directed against the direction of the laser beam. For free atoms you therefore need three pairs of counter-propagating beams to achieve overall cooling. If the atoms are somehow conf
