The graphite piles in Hanford have literally nothing in common with PWRs or BWRs that are used for power generation.

No, this is fundamentally impossible. There are infinitely many possible objects that would produce the same blurry image.

The resolution of these telescopes is limited by diffraction, not by the number of pixels on the sensors. The achievable angular resolution is roughly the wavelength divided by the aperture diameter [1]. JWST works in the few µm wavelength

This is not published in Nature. Scientific reports is much less prestigious and selective.

Tritium is highly radioactive (358 TBq/g). Otherwise it wouldn't make phosphors glow in the dark.

Other limitations in GNSS accuracy are that the satellite clocks drift and that the orbits are not perfectly know in real time. GNSS operators regularly publish correction files for the clock and orbits. This allows post-correcting the reco

What you are describing is essentially a "frequency chain" which was historically used for measuring the frequency of laser light. The idea is to start with a cesium atomic clock which (by definition) has a frequency of 9 192 631

Sure, if your CPU is controlling an airplane, it should better be redundant. Still, the CPUs inside your laptop, smartphone, or even compute server do their jobs pretty well without any error correction. The transistors inside a digital CPU

Regular CPUs don't have error correction. The logic gates simply don't make mistakes, even after trillions of operations. The reason is that the gates are digital. Manufacturing imperfections and noise don't matter, as long a

All x86 CPUs sold after 2015 or so have built-in hardware random number generators [1]. They get their entropy by sampling thermal noise on the input of a meta-stable logic gate [2]. [1] https://en.wikipedia.org/wiki/RD

No, the scaling is definitely done by the applications. I don't know how they do it, but it works. I don't think it is possible to avoid having lines "in between" pixels when using fractional scaling. The physical pixel

The article is about animal CMVs, not human CMV. "Nuismer and Redwood both say it is highly unlikely that a CMV-based vaccine could ever jump species given the virus’s biology. Although the evolutionary factors underlying CMV’s species

That ship has sailed roughly 12000 years ago [1]. By mass, around 96% of mammals are either humans or lifestock [2]. If you go on google earth and zoom into a random country anywhere on earth, chances are pretty good that you end up looking

It is not clear to me what exactly the relevance of the first bug is. Text in all Wayland programs is perfectly clear on my system with 150% fractional scaling. I can reproduce some of the effects from the second bug when looking at my 4K m

This is incorrect. I use fractional scaling in Gnome Wayland for my 4K monitor. The native Wayland software (Firefox, all the Gnome stuff,...) scales perfectly. Only XWayland applications are somewhat blurry.

What exactly is the issue? OBS (currently version 27.2.3) works perfectly fine on my machine using Gnome Wayland.

Good. Human spaceflight is mostly symbolic anyway, and there are plenty other launch vehicles for the satellites that do the actual science.

I really wonder which effects this kind of user-hostile behavior has on the long term success of a company. This is probably impossible to measure since there is no second Amazon to compare with. I guess some execs were asked or incentivize

Only hadrons (neutrons, protons, mesons,...) consist of quarks. Positrons are leptons which are elementary particles.

It doesn't. The ground state orbital of the antiproton is in principle stable, just like the electron orbitals in a regular atom. The difference is that antiprotons can annihilate with protons from the helium nucleus when they get too

Antiprotons can be stored pretty much indefinitely (many years) in cryogenic Penning traps. This is done by the BASE collaboration at CERN [1] who are actually neighbors of the group that the article is about. [1] https://base.we
