Unlike previously cut cables, which were mostly communication fiber cables, this particular one is a power cable and during the cut it was delivering 650MW at 450kV [1] so almost 1450A of current. If it was cut by accident by an anchor I co

Acceleration signature depends on: - human driver - train capacity and current load - train model (or any powertrain variations) More reliable might be to check rail track features from accelerometer: tilt, turns, bumps, or a combinations o

Nice game. @author Please just consider removing super-thrust effect when booster is punctured. Obviously engines have much more thrust than the gas escaping through the puncture, so crazy rotations after puncture are not realistic at all.

While being in general interesting (and comprehensive, it seems) study, the provided impact on space travel in the press release is purelly hilarious: > Even a slight deviation of just one centimetre on Earth can grow to a deviation of h

Generally this is a correct argument - to compare hardware one needs to use the same OS/software stack. But the argument works the other way around also, if there is no identical software stack possible does it really matter how raw ha

I use Airpods Pro (1st before and now 2nd gen) with Android phones. And indeed no way to update firmware from Android, no way to check firmware version, no way to select modes, no way to change long press behaviour, no way to check battery

Car manufacturers' interconnecion is amazing by itself. Direct "competitors" share engines, gear boxes [1], or the whole vehicle [2] (modifying just interior and badges, of course). Seems like they adopt the same strategy as

/s I wonder how close we are with phones to what was back in 50-80s with smoking [1]. Maybe in 100 years, people will look back at early/mid 21th century and call it "like the Wild West". 1. https://www.cdc.go

Better the opposite - date by default and on hover human readable. People would more likely want to copy the actual date than the human readable delta.

Metal coating (Al, Ag, Au) is reflective in very wide range of wavelengths - from far IR to EUV [1]. 1. https://en.m.wikipedia.org/wiki/Reflectance

If target is metal coated with gold, silver or aluminium layer [1], then the reflectivity is good from UV up to far IR. 1. https://en.m.wikipedia.org/wiki/Reflectance

This "law" is only for point (or spherical) sources, i.e. those emitting evenly in all direction - the area is increasing as a square of distance and thus signal power drops accordingly. With lasers, directional antennas, phased a

Cold gas thrusters are as reliable (because of simplicity - basically just container of pressurised gas and a valve [1]) and as precise in their thrust pulses execution as it can get. Better precision in thrust execution probably only ion e

Not really. An example out of top of my head, where this still might be useful are login nodes (used in many research clusters to allow users to enter and sumbit jobs) or shared web-hosting servers (few of those definitely still exist). The

Technically you can (licensing though needs to be checked). Just check/inspect the code of the page, look for video tag and see the source url, e.g. [0] 0. https://bleuje.com/mp4set/2021/2021_01.mp4 P.S. You

Indeed, all those animations are pre-rendered videos embedded in the page, which are then randomly selected. I find shadertoy [1] really impressive, given that those animations are calculated/rendered in real-time. A while ago after be

Art may be useful (or at least usable and realistic), e.g. imagine providing instructions how to get the photo from that camera for (hopefully) people in 1000 years, or even describe what that cilinder on a pole is in the first place. Scien

My favorite genre of astrophotography involving perfect alignment are photos of ISS transits over the Sun or Moon, e.g. [1], [2]. There is even a website which caluclates such transits [3]. Destin from "Smarter Every Day" made a v

Gemini made a mistake, when asked if the rubber duck floats, it says (after squeaking comment): "it is a rubber duck, it is made of a material which is less dense than water". Nope... rubber is not less dense (and yes, I checked a

Mars might be just a first (easiest) step for becoming multi-planetary/spacefaring civilization. By itself it is not that special or important but if you have a colony on another planet you focus more on space technology and other opti

All these policy prompts remind me laws of robotics by Asimov [1], and definitely our current 'robots' frequently violate them. Asimov's laws are more logical since those are hierarchical with high-to-low prioritization and s

Yes, if a Nobel prize is given for two different topics (for three people, first person - one topic, other two - another topic) then 1/2, 1/4, 1/4 shares will be assigned, for example the prize in physics in 2019 [1]. 1. htt

Do you have a reference on any of those? I can only find papers about lab setups. Since wavelength of IR is much shorter phase control of different emitter is much harder to accomplish than in the radio. Moreover thermal deformation of the

For the CMB we predict (or rather invent) "inflation" - a rapid expansion of the space-time to preserve uniformity of early Universe [1]. Inflation lasted for 0.00000000000000000000000000000001s but the size of the Universe increa

People seem to miss that better filters it is not just about higher price, but also higher CO2 emissions - filters decrease efficiency of the engine since they take energy to operate, moreover the energy consumption increases nonlinearly w
