c has unit m/s t has unit s λ has unit m so ( m/s * s ) / m is unitless scalar.. How did you get such value? For visible light? N = 299792458 m/s * 1s / 400*10^-9 m = 0.00074948114 for 400 nm wavelength N' = 299792458 m/s * 1s / 700*10^-9 m = 0.00042827494 for 700 nm wavelength

If you install an operating system from scratch, you select and install the correct drivers for the correct hardware... when you connect the disk to other hardware, it may have completely different hardware that is incompatible with what is installed on the disk... config files are screwed/damaged...

It's capitalism! Gun industry owner teaches kids to use/own the things he makes they make young and easy for brainwash..

I've said this before, but since mortals' memory is pretty poor, so I'll repeat it: The problem is not with people with mental health problems, The problem does not lie with people with right-wing beliefs, (dunno why) they want to carry gun, carry machine guns.. (maybe they want to piss me off) The problem is that industry, lobbies and shareholders are behind them.... Buy them back and shoot them down... change profile.... Let them produce something useful for society....

Books don't matter. What matters is how you spend your free time. Do you write your own apps for Android/iOS/Web etc., or do you drink beer with friends in a pub/club? Install Android Studio, make Android app, install iOS XCode, make app, install Xamarin, make app, and so on, so on.. (You can drink, if you're able to think clearly... )

...you can't plug in disks formatted and configured for another system, and just plug them into another system.... this will lead to more problems than it solves.... have pendrives with the installation version of the win10/win7 operating system, and plug them into the computer, and install things from scratch from them.... Tip: Go to https://www.microsoft.com/pl-pl/software-download/windows10ISO and press ctrl-shift-m and pretend other operating system than Windows, (if you won't, ISO won't be downloaded, instead special net-installer version) to download Windows ISO file, and save it somewhere (e.g. pendrive) use e.g. Rufus to burn on pendrive to have installation pendrive.. Then you can install Win(X) on laptops without physical CD/DVD (like mine).. ps. Buy multiple 8 GB+ pendrives.. 5 usd/each for 32 GB here.. one for Win7, other one for Win10 32 bit, another one for Win10 64 bit, and some more for Linuxes..

Like any variable.. Only mathematical constants can't be changed.. The question is, if you want to change the U.S. constitution change, one way or another.. Do you want Elisabeth replacement? or Boris? Sorry! Where is the backspace key? (at least with the invasion he went well.. and got some serious points from me) ps. My point was the Constitution can be changed the way you won't accept it..

Please don't abuse your free will or sysadmin of the Universe will log you out (aka "sudo ban [person-id]")..

You sound like Donald T. and V.P. ... In what way? Donald wanted to change the Constitution. https://www.google.com/search?q=donald+trump+want+to+change+constitution V.P. changed constitution, to his purpose. https://en.wikipedia.org/wiki/2020_Russian_constitutional_referendum i.e., if you say "the constitution can be changed", you also mean "the constitution can be changed in ways you don't want and you won't like" (half the population won't like your constitutional changes)... like in Russia.... or in China.... https://www.bbc.com/news/world-asia-china-43361276 "The constitution has been altered to allow Xi Jinping to remain as president beyond two terms and they would not have gone to this much trouble if that was not exactly what he intended to do." ...so be careful what you ask for, because you might get it....

You sound like Donald T. and V.P. ... (they too dream, wish, initiate change for their will) Make an amendment that the president is Jesus It will be easier (at least you won't waste time and money voting) ...another remnant from the distant past... originated in the days when firearms fired one shot per minute or less.... so basically one person could shoot one person at a time and run away.. So... if I create laser pistol, laser "rifle", or whatever, which is not "firearm"... can have it? (just kidding, nobody would believe I have laser rifle) (don't have to break in my house, it's not here.. keep it in a safe place! )

Around here I don't know anyone who has a gun who isn't a criminal.... The gun industry wants EVERYONE to have a gun.... just like the tampon company wants every woman to have their product.. The fight with it is not as simple as forbidding tampon..

I was creating Tetraquarks..

DUST, BUDS, CUTS, TUBS, CUBS, DUBS PUTS, NUTS, PETS, BEST, PEST, NETS

This program is incorrect. It does not take into account leap years..

V2 rocket had maximum speed 5760 km/h, which is 4.66 mach. https://www.google.com/search?q=5760+km%2Fh+to+mach (Google let's you convert speed to mach, nice!)

I am used to ray-tracing like this: Have ray-origin vector. Can be 2D vector, or 3D vector. A simple C++ class with two or three fields and some methods which do the basic math with them. Have ray-direction vector. It's normalized, unit vector. Have some primitives. Can be triangles, planes, circles, spheres. Whatever. Algorithm of finding intersection changes with each primitive type (yet another C++ class with methods). Ray-tracing procedure returns scalar output, which is distance. hit_position = ray_origin + ray_direction * distance (if intersection procedure finds hit_position, it has to reverse equation to return scalar i.e. distance = ( hit_position - ray_origin ) / ray_direction (careful with division by zero here)) If primitive is sphere or circle, ray can intersect in zero, one or two places. The smallest distance from ray_origin is the right one, and second one is skipped. If you would provide the source code, it could be more fruitful discussion..

Does it matter who? These days, engineers or scientists work in large teams..

Information is data. Data does not do anything. Algorithms working with the provided data do something, i.e., change the data according to the algorithm. A dead or frozen body is a handful of data. Non-organics body too. e.g. piece of rock molten billions years ago, is giving paleontologists, geologists etc. plentiful useful information

D.T. "progressive" (using your definition of the word)? Seriously? https://www.nature.com/articles/d41586-020-02800-9 "How Trump damaged science — and why it could take decades to recover" https://www.washingtonpost.com/news/energy-environment/wp/2016/12/27/scientists-just-ran-the-numbers-on-how-much-trump-could-damage-the-planet/ "Scientists just ran the numbers on how much Trump could damage the planet" https://climate.law.columbia.edu/content/president-trump-announces-withdrawal-paris-agreement-0 "President Trump Announces Withdrawal From Paris Agreement" ...plus countless other examples that directly contradict the definition...

...that is very very strange statement... ray-tracing happens in 3D world space.. then these vertices are projected to 2D screen space.. and then they are on the screen ("pixels").. when you do ray-tracing, there is no such thing as "pixels"..

..the purpose of these sites was not to make a profit.. at least not for investors.. Before Google or Facebook made any tiny dollar, they had billions of dollars invested in their servers.. Their investors were "screwed up".. "how to monetize our business" was after they had their listing on stock markets.. (Faceook had a long way to go to bottom in price once it was listed. -50%.. if somebody survived, is happy now) Now, actually, they became piece of shit.. Not from monetary point of view, but from my point of view.. ps. I remember people asking me about whether I bought FB stocks on the primary listing.. funny., funny.. mortal beings..

..not really.. ..if a group of people are using the same trend analysis tools and following what they see on the screen, they are creating trends themselves.. https://en.wikipedia.org/wiki/Self-fulfilling_prophecy ...and even "worse" if they are not real people, but bots playing, predicting and following trends... you can be sure they will follow trends if they have been so programmed by the creator..

Plants (with seeds, which they tried) are multicellular organisms. They (i.e. scientists working on this project) should be successful with unicellular organisms first (e.g. air nitrogen-fixing ones?), and then try with multicellular ones because they are more challenging. Then check the cooperation between the nitrogen-fixing unicellular microorganisms and the multicellular ones, which will use nitrogen compounds created for them.

Lol. You should worship Frankenstein, not Jesus or Mo In the novel, Victor Frankenstein was a SCIENTIST who resurrected his monster.. He (the scientist) was not struck by any lightning..

https://www.google.com/search?q=moon+soil+chemical+composition Nitrogen is not on the list of elements.. "The bulk chemical composition of lunar dust varies across the lunar surface, but is about 50% SiO2, 15% Al2O3, 10% CaO, 10% MgO, 5% TiO2 and 5-15% iron (Table 1), with lesser amounts of sodium, potassium, chromium, zirconium." On Earth, nitrogen compounds found in soil are produced during lightning strikes and by nitrogen-fixing microorganisms.
