humans are still massively retarded, like this anon here

I’ve wanted to become and engineer for years, but I’m too stupid to get into the field (or any STEM field)
Genuinely depressed about this. Maybe I was just born to be a grunt in the army

I’m a 94 IQ (irl tested) retard.
Explain this superconductivity thing to me in terms I could understand

Not an argument.

2 = 2
is there any ways to change the number with out adding or taking numbers

help am I dumb?

give it to me straight, /med/oids

is ophthalmology a good specialization for the future? what with all the people who're spending hours upon hours in front of a screen, especially during times like these?

>t. mathoid

/med/oids i require help

if, say, i shaved my moustache, will hair particles or follicles or whatever they are go up my nose when i breathe and go to my brain?

I'm genuinely curious

>be me
>do an exercise for my physics class
>my answer is not the same as the one at the back of the book
>spend an hour redoing the same problem 4 times
>suddenly teacher sends a message on the group class
>apparently the answer at the end of the book was wrong and mine was correct but our teacher forgot to mention this to us

does this happen to you in/sci/ects

i'm currently studying C++ but i can't wrap my head around it
we're doing basic stuff, like finding the max length of strings, manipulating character strings, matrixes
basic stuff for HS

my teachers tell me that my algorithm ideas are fine, but i can't implement them
this is what i don't understand
afaik, people who are good at maths are also good at coding, but I'm just good at maths

Prove:
An integer is a perfect square if k^2=n. If k and m are both perfect squares, then m*k is also a perfect square.
Proof:
Let log base be k
Then log(n)=log(m)=2
Then log(n*m)=2+2(by log product rule)=4=2^2 and thus m*n is also a perfect square

Pic related is me btw

Why are frequentists allowed to walk the streets freely, /sci/? Surely they should be institutionalized for their own protection.

brainlet here

can someone explain to me how the observable universe is 46.5 billion light-years across, but only 13.8 billion years old?

Did the universe expand faster than light?
If everything started at an infinitely small point almost 14 billion years ago, how did they move so far away from eachother so fast?

>I bet those scientists don't know CO2 is plants' food
>i bet those scientists don't know earth's climate was changing in the past lmaoooo at these retards
>i bet they also don't know there is something called solar cycles. How could they know amirite?
