is the electromagnetic spectrum a natural resource?

why

Fake image. Human eye can only see 3 waves: red, green and blue. All other colors is just mix of 3. Violet, yellow and other waves not exist!
I was making spaghetti and I lost track of time, came back to find it burnt. Initially my reaction was "ohhhhfuckmeintheasshol how am I gonna eat this now?" and then I got to thinking; raw meat has bacteria and shit and you shouldn't eat that, so you cook it to kill all them bugs n shit with heat. So surely, if you burn it to a crisp, you've killed more bacteria, there are less diseases lurking on there, and therefore, burnt food is healthier.
Also, I ate the burnt spaghetti and it was fucking delicious, just the meatballs were a bit crunchy.T
I think it's a question that suits /ck/ better
>>8131549
1) Enjoy your free radicals (cancer).
2) Cooking is more to denature proteins than to kill bacteria
"burned" food has a different structure and is processed differently
If I put an electromagnet in the water would it still work? Would the water make the magnet weaker/stronger or would the field be unchanged?
It would make the magnet wet
>>8131570
It would be quantum wet, in a state where it is wet and not wet until a human puts their hand in the water to collapse the wave function by creating a literal wave.
Run the current and try it, OP.

Make sure you're grounded tho. Otherwise you might kill.
If you haven't read and thoroughly understand this book, I urge you to quietly pack your stuff and leave this board by tomorrow.
>>8131519
Nah, don't leave. Just read the book. It will be well worth your time.
" [...] you never can make a lawyer if you do not understand what demonstrate means; and I left my situation in Springfield, went home to my father's house, and stayed there till I could give any proposition in the six books of Euclid at sight. I then found out what demonstrate means, and went back to my law studies." - Abraham Lincoln

what should i read first, this or Calculus: an Intuitive and Physical Approach?
We need legit science up in here /sci/
Well, might I suggest that instead of starting shit threads, you might start one on an interesting scientific topic?

I dunno. Blame the patriarchy I guess.

Explain. Doesn't shit like this put a dent in peoples minds like how they perceive scientists ? Even on a minor scale, isn't this a psychological setback for the perception of scientists on the population ?

Scientists are the priests of today, and like the priests yesterday, scientists are just as hedonistic as other people.

as in lacking reflexivity. THe sole fact that they accept to be praised like priests show how egotistic they are.

What does everyone think about LaTeX for writing notes? I've been using word to write mine but am getting sick of the equation editor. Is learning how to use LaTeX worth it in the long run?
Can you use japanese characters in LaTeX?
What are some beginner tips that will make my life easier

>What does everyone think about LaTeX for writing notes?
I do it. I like it
> Can you use japanese characters in LaTeX?
probably
> What are some beginner tips that will make my life easier
get a template and just start playing around.
>>8130965
I actually prefer taking notes with pandoc markdown. It supports the same equations, but is generally faster/easier to use. I still use LaTeX for anything more serious though.
LaTeX is not hard at all. The only things that are sort of a pain in the ass are matrices or trying to put weird alignment on many equations.
What does /sci/ think of hydrogen powered cars for the future? Would it be possible and how much would it cost?
>>8130800
Given the high price of fuel cells and the difficulties with handling hydrogen, it seems hard to imagine much of a future for them. Battery-electric vehicles appear to be heading to dominate short-rage travel, so hydrogen vehicles would have to compete with petrol and diesel on longer trips.
I am surprised that no-one has discussed vehicles running fuel cells on other fuels. Methanol in particular would seem like a reasonable option.

NASA tested Stirling engines and said they were great

>NASA tested Stirling engines and said they were great
What? When did that happen?
The only NASA research I've head of on Stirling engines was their radioisotope Stirling generator for spacecraft, and that thing got canned in a budget cut a few years back (which was a shame).
All of the work on Stirling-powered cars I can recall happens decades ago, was primarally done in Japan, and found the manufacturing costs were too expensive and the power density couldn't...

What would it look like? A chimpanzee, or a bipedal ape like Sahelanthropus?

Why do people believe in free will? If we observe nature we see that everything is determinated by the laws of physics, biology etc. Why would humans be different?

because we have souls
>>8130650
What?
>>8130657
Souls are apart from the physical world and belong to another realm that we can't comprehend. So they are not dictated by the pre-determined laws of physics or maths. This is what separates from the inanimate rocks and this is how we have consciousness.

How smart is he really?
I heard he got rich making an html phone book in notepad.exe and now everyone think's he's a genius.
smart, but definitely overrated.
he entered uni at 19 for one.
>>8130475
Smart enough to get rich and be a household name :^)
But, if you'd like, you can foster delusional feelings of superiority out of insecurity :^)
He has what psychologists refer to as "narrow intelligence"; meaning he's basically a high functioning autist.
Easiest way to detect an autist:
1.) Do they comprehend normal social rules
2.) Are there understandings and interests exceptionally narrow
3.) Do they have OCD behaviors
4.) Can they comprehend being incorrect
So he's basically an autist.
So was Howard Hughes [also had multiple other disorders], Bill Gates [also antisocial personality disorder], etc.
It's not uncommon for high functioning autists to corner a...

Question /sci/
How easy would it be for one man to farm an island by himself if he had a small army of machines and systems with AI good enough to do a lot of tasks such as sowing seeds, watering crops, taking care of livestock etc? As it is now, its very difficult for a person to do all this for self sustaining purposes and even more difficult if they are old, but with the help of robots maybe it can be done?
>>8130423
It's cheaper and easier to hire Philipino peasants for this.

it would still be easier to shag ur mum

How the hell did they get voice activated commands working in 1939??
https://www.youtube.com/watch?v=AuyTRbj8QSA
>>8130351
if you have prerecorded commands based on his voice and dialect. then it is only a threshold similarity between the word he says and the word he can hear.
or else its fake and its all scripted. most of it is scripted anyways probably
>1939
>just invented electricity
>voiced by phil harris (baloo, jungle book)
>just happens to be tall with thick legs and a very wide torso
mfw brainlets actually think this was a real robot and not just some cuck in a suit
>>8130381
His voice was done by a record player evidently.
Watching the video, it appears that after the command is entered, the rest of the action is scripted, but the command looks legit. I don't think the operator would talk so mechanically if it wasn't. Then again, there's no proof that it wasn't completely scripted.
This was the time around when radar was being developed. Perhaps they had an analog circuit that could cross correlate a voice signal with a recorded signal, or perhaps they...
