Actually it is not easier at all, the complexity is obscured by an onboard computer, which constantly helps to keep position, not to flip upside down and lose control completely. By applying differential thrust on different propellers it e

There is a physical reason for that - all the generators connected to the grid, including massive nuclear/coal-steam-turbine powered ones, literally slow down due to increased load. Thats why in AC grid actually the frequency decreases

Currently I have a related task, a telescope is being operated using a set of old hardware (late 90s-early 00s) and same age software, due to current situation in case of lock-downs the observations are not performed, so the idea is to migr

Hydrogen is not a good (at the moment at least) source of energy or fuel for cars or industry (chemically speaking, obviously much better together with Deuterium and Tritium for fission, though we are still from such a technology). Steam re

This table was also featured at Astronomy Picture Of the Day website (APOD for short) few days ago [1]. Judging by the tags in the tweet, author took it from there. [1] https://apod.nasa.gov/apod/ap200809.html P.S. Aft

Just to put a bit of a context here, life exists on Earth for 4 billion years (single celled), and 1.5 billion years (multicellular) [1]. There were few mass extinction events in the history of Earth, at least 5 happened in the last 540 mil

A bit off-topic, but whoever is interested in such during- and post-apocalyptic scenarios from sci-fi point of view may want to check the Seveneves book by Neal Stephenson [1]. One of my personal favourites. [1] https://en.wikipe

While looking for more info on Kharkovhanka 2, I found a blog of a russian guy who actually lives on the Vostok station [1]. There is an additional engine+generator inside [2], which is used for heating of the interior, but probably can als

Few facts from the excellent An-225 pilot interview and the plane tour video [1] put by @prehistoricdog in this comment section: - The plane, when empty, can fly for about 16 hours without refueling covering about 13000 km - Cruise speed is

Yes, An-124 is indeed a good cheaper alternative with comparable capabilities for this kind of cargo, but in March-April it seems there was a high demand on all Antonov fleet [1] plus the PR factor is not playing the last role here. [1] ht

Maybe it was a political stunt, but actually there are two justification of that. 1) The volume. The masks and other protective gear is volume-demanding cargo, since the overall density including packing (boxes) is low. The Boeing 777 Freig

P.S. By saying that I'm not suggesting we should decrease the amount of resources for research, actually the opposite, since misuse is a fraction of the whole process and some discoveries would not be possible without such mistakes. We

Generally I agree, I also contributed to SETI@Home and Folding@Home. The aim is somewhat "strange", but the whole value of all this may actually be not in the aim itself, but in the activity to reach it, particularly algorithms an

Exactly, speed of light in the vacuum ( c ) is the hard limit, only mass-less objects can move that fast (e.g. photons). The refraction index ( n ) tells you how fast light moves in a medium. It is defined as n=c/v , where v is the

The atmosphere is also used as a detection medium for Imaging Atmospheric Cherenkov Telescopes (IACTs) [1]. Very high energy (>tens GeV) photons, electrons or nuclons hit atoms in the atmosphere and produce a cascade of secondary particl

Noise cancelling works by shifting the sound waves of noise, which come into your ears. The ups and downs (of pressure) in the sound wave are added together, cancelling the wave altogether. Each ear get different noise, so the microphones

Actually we do understand all the things which happen during normal conditions with light (i.e. when we speak about: bunches of photons and not a single one; objects big enough so that quantum effects can be neglected; relatively low intens

Actually something like that may indeed happen, but spontaneously, see about vacuum decay here [1]. Roughly speaking, the vacuum we know is meta-stable and eventually it can reach its zero state, but such change in any point in space will t
