Would you consider gas technician a science.
currently taking it and we do a considerable amount of chemistry on paper. The course's actually name is HRAC??
You gonna learn how to restart pilot lights?

Hello /sci/!
I'm being curious and I'm struggling hard to find a reliable answer on the internet, so here is my problem. What is the TOTAL margin of error in our current knowledge/measurement of the speed of light?
Wikipedia only partially answers on the following article:
>https://en.wikipedia.org/wiki/Metre#Distance_travelled_by_light_in_a_specified_time
Several limiting factors are listed, but only a few of them are given numeric values, and I suspect there may be more limiting factors, non-listed in the article.
I'm interested in the numbers as well as in their explanations.
[spoiler]Obviously, don't express your answer in metters, as the metter is defined by the speed of light. Instead, you can use as a length unit things like the wenglenth of a laser, the Planck's length, or a simple percentage (as in "±1%").[/spoiler]
>>7775472
Well. Spoiler fail, I guess.
>>7775472
Noone is interested in this question?..
>>7775862
planck length is hypothetical and doesn't exist idiot. ask a question based on reality and not pop-sci next time.
Your brain is using too much power and if you don't do anything about it, you will die. In order to survive, you must choose one of the three brain systems to shut off. Doing this will make the other two work three-hundred percent more efficiently, but, you permanently lose the system you chose to shut down.
Which of the three brain systems do you shut off and why?
>>7775382
I want to not die. And I want to be able to remember things. So goodbye, limbic.
Quite the "delima", but I'd take death over any of those options,
>>7775409
You won't remember much for very long without a limbic system. But yeah, the other options are death and brain death, so goodbye emotions I guess.
ITT: post ways the human body is fucking awesome
>be in dangerous situation
>body floods itself with steroids so it can run faster, jump higher, and fight harder
>no teeth or claws to hunt with
>intelligence and endurance to track and chase whatever you're hunting until it keels over and dies from exhaustion
>>7775330
What is the point of this thread?
The human body is trash the only redeemable feature is the brain and it doesn't even work properly for 99% of people
How much Technical (Software/IT) knowledge does a 1st year anyone of the above corporate roles (Software Sales Engineer / Solutions Architect / Technical Account Executive) actually need to know?
I'm great at selling B2B, however I am trying to gauge how many months I am going to need to study C# at 10 hours a week in between my current job in order to achieve at anyone of the above three roles within a company.
Thanks for the advice.

>>>/g/ayfags are that way
Want to know if there is a better way to go about this problem.
Something nags at me that expanding the squares after squaring both sides is unnecessarily tedious.
>>7775203
if you write y= (1+i)z = sqrt(2)*exp(i*pi/4)*z,
then y describes the circle of center 2 and of radius 4
which means z describes the circle of center 2 and of radius 2sqrt(2)
>>7775217
also maybe I'm just saying shit so be careful.
>>7775203
You definitely want to isolate the z so maybe do (1+i)z-2=(1+i)(z-(1-i))?

Why is desalinization such an expensive and underutilized process? It seems relatively simple, especially in wealthy, modern countries.
>>7775107
It takes a fuckton of energy to boil water.
It really isn't very expensive, just an effect of capitalism and supply and demand
>literally shitting and pissing in drinking water then flushing it down into the sewerage
There is no need for desalination.
What kind of job you can have after studying physic engineer ?
I too would be interested in knowing it. What can you do after majoring in engineering physics for your undergrad?
McDonalds, probably management.
In what ways is making math like making music?
Both lend themselves excellently to being a pretentious 2deep4u shitlord or a pretty cool guy.
not at all
>>7774991
100% the same thing. One time I read a linear algebra book and one of the pages was just pure sheet music. I then had to take an exam where I had to prove a statement using music.
Why the big bang happened? Why does life exist? It stranges me out to think about, that I'm able to think, see, hear, interact, etc. Why?
>>7774821
if you're looking to find out how, it won't satiate your discomfort.
If you're looking to find a purpose for it's development, not only will you never find it but you're in the wrong board...
>>7774821
There is no why in science only how. If u want answers to bad there are none.
Which branch of science is easiest?
>and why is it biology?
>because memorization
>>7774654
Is that a real quote?
Personally, I find stuff that needs plenty of memorization more difficult than mathematics. I get bored as fuck having to memorise loads of stuff.
epic bro xD biology not a hard science still 2010 guys forcing this meme for six fucking years now
Biology is a pretty broad field. There's cellular bio, microbiology, biotechnology, biochemistry, genetics, zoology, you can't really make generalizations about it
Anybody else wired up by the latest additive manufactured Nasa engine?

Also, Nasa has been doing some 3d printing in space but today it's only plastic extrusion.
How about metals? We are pretty advanced on this tech on earth (like this breadboard engine) but on the ISS it doesn't seem to be in the pipe on shorterm
https://www.youtube.com/watch?v=oGWPR0mcCLs
what are the complications that would make it hard to do in space?
I suppose the layering of metal wouldn't work in microgravity?
>>7774326
a schematic to understand the engineering of a metal part with metal sintering
>>7774351
So for practical reasons, the powder layer would probably be unpractical, it would fly on all directions. But that can be compensated if the aparatus rotates on itself at a high enough speed to create some kind of microgravity that would maintain the powder in place through centrifuge force.
Now the finishing of the part might prove trickier, see the vid.
If i turn the grayscale on my I phone on, will that black the blue light? Im trying to not inhibit melatonin production at night.
>>7773819
block, my apologies
Aren't there apps that removes the blue light? Like f.lux? I don't think grayscale would do much of a difference actually.
