You guys got any stories about some dumb interns or people at your work?
Some people clearing show they don't know jackshit and somehow still get hired.

I had a newbie dogman direct the crane i was operating through a fresh brick wall. Brought the entire wall crashing down two stories and cleaned up 15 metres of 3 story heavy duty scaffold with it. 5 minutes earlier there had been 4 brickies on the scaff. First and only time in my life i've completely lost control and assaulted someone. To this day i struggle to believe no one was killed or injured considering the odds

Freshman math major who just applied for an internship bumping for interest.
I really want to know other's fuck ups if only to make me more aware of myself so that I don't become one of these stories.
>that grammar in OP
Yes, OP. That would be you, if you have to write anything at your job.
Hey /Sci.
So before the Big Bang, "everything" was nothing and nothing was not existing. After the end of the universe, everything that exists will all decay into photons and the universe will then return back into the state of nothing and non-existence.
So is the point of existence to return to the state of not existing?
Was the Big Bang and creation of time an anomaly, and the state of everything was to be nothing?
>So before the Big Bang
we don't even know if this is a thing; time apparently began with the big bang
>After the end of the universe, everything that exists will all decay into photons and the universe will then return back into the state of nothing and non-existence.

there is no point to existence whatsoever

You're gonna have to back that up with evidence or an explanation.

you have made another claim without evidence

Can i cheat at sport using this math tactic?
My friend is an umpire and has to toss a coin at the start of the game and i call heads or tails and if i win i get to choose which way to play and gain an advantage. If i lose the other teams captain chooses and gets an advantage.
I talk to him the night before and he says to me to call heads. (hes helping me cheat)
That night at home he sits there tossing the coin thousands of times until it lands tails 4 times in a row. He then keeps the coin totally still and makes sure it doesn't move until he brings...

No, this is called something called 'Gambler's fallacy'. Look it up.

The only way this is working is if your friend gets REALLY good at flipping coins accurate on heads or tails.
Hello /sci/,
I'm making a little [spoiler]videogame[/spoiler] and I was wondering if anyone could help me by telling me the smallest particle that makes up another particle (that makes up another, etc. etc.)
Tell me if i'm incorrect about how this should work:
A player vibrates a string. Once the wave's amplitude is large enough the string becomes a quark, which is then turned into a proton. I can figure out the rest from there, but am I incorrect? Is there something that makes up a quark (leptons)? Should the string instead become a lepton?
This...

oh would you look at that, spoilers don't work on this board
Forgive my autism, friends.
The particles in the picture are the ones that are elementary.
However your understanding of how they arise in a String Theoretic description is way oversimplified.
>>7767175
Of course, I don't claim to know anything at all about string theory. But it will work for the purposes of my game, as long as the basis is relatively correct; which i assume by the way your post is worded, it is.
How reliable does /sci/ think Khan Academy is? I'm currently thinking of using it to learn pre-calculus before teaching myself calculus, with the hopes of learning higher level math subjects(for my own pleasure/hobby).
Is the site good? If you don't think so, please elaborate on your reasoning or simply outline the flaws it possesses.
Thanks in advance
two other sites worth noting are

>>7767137
I'll look into them, thanks anon.
I think it would be better to buy a book, read it. If you don't understand something, then use Khan Academy.
if you saw only a picture of the moon, how could you tell where the sun was when the picture was taken? Thanks for the help
I can't even tell if this is bait.

RIP
for prime number-fags: I'm trying, just for fun, to figure out how to prove the following property of prime numbers: given three consecutive prime numbers x, y, z, the bigger they are the more their sum x\y + y\z + z\x tends to be 6. any suggestion?
its actually 3, not 6
prove it for consecutive integers first, then look up the properties of primes on wikipedia and see that the proof for primes is just as trivial
>>7766655
It is very easy to prove it false. Take three random consecutive primes and test those ratios. They will be very far away from six.
Then take another three bigger consecutive primes. They will be even more far away from six. Theorem discarded.
if
x < y < z
then in
x\y + y\z + z\x
the first two are smaller than 1 and the last is quite big.
I don't see how this would converge to something small.
Whew lads looks like i fucked up big time. Due to incredible amounts of procrastination, i only have 2 weeks left to study to test out of pre calc and go staight into calculus. Is this possible? how many hours will i have to put in a day to reach this goal
If you are not retarded, then it's going to be easy.
>>7766653
If you need to cram to test out of precalc, you shouldn't be trying to skip precalc.

Why is wind cold? If wind is the moving of air molecules wouldn't that mean they are being acted on by a force? And isn't heat the rapid moving of molecules due to energy?
I'm not sure my question is clear but I imagine wind being air molecules gaining energy and moving and that heat is energy in molecules
Sunlight mostly passes through the air, and warms the ground instead. Additionally, the inside of our earth is much hotter than outer space, but i think the crust insulates most of that heat anyway
The "movingness" of the air molecules is irrelevant because the ground's molecules are moving even more, this is already reflected in the temperature, NOT the wind speed.
So air is typically colder than the ground.
Wind feels even colder than static air because of convection. The quick,moving air just increase the thermal transfer rate

>The full answer to this involves a couple of subtle issues, but I like to start with a simple-but-cool fact, which is that the speed of wind just isn’t that big a change in the speed of an air molecule.
> you find that the rms average speed of a molecule of a nitrogen molecule in air is a bit more than 500 m/s. For reference, the speed of sound in air is around 330 m/s, so any given nitrogen molecule in the air you’re breathing...

How does one go about making a scientific paper? I am a first year college student, but recent experiences have lead me to believe that it would be possible to work on something and maybe publishing it during college. Namely, asking one of my profs about various things and getting a surprisingly positive response, while catching from other sources that certain students are selected from the first/second years and tutored/taken in as assistants. But still, I don't know what to do.
Do I ask the teachers and they give me something to do or what?...

Will a computer science degree become worthless as hardware becomes cheaper and more powerful, and bruteforcing solutions will be possible?
How will quantum computers affect this?
No, because quantum computers are not infinitely fast and do not have infinite memory.
my god go read a book please
Computer science will always be useful, so long as there idiots like you.
Hey so i am working on an artpeice.
I want to use the image of a neuron connecting to another to symbolise positive change and the actual science of habits and thoughts building your reality.
I am no sciencer. but i was inspired by a friend of mine's explanation that emotions are the result of neurons connecting or detaching as you form or destroy new associations etc
I dont think i know enough to research wether this is actually true or works like that and id like to understand more before i use a neuron as symbolism. I also understabd theres multiple kinds...

Why? Because you want to be an engineer? Wrench monkey? Hate clear night sky, advanced optics, mysteries of the stars?
>>7766368
That is literally the most meme degree you can get.
>>7766368
Because Astrophysics is boring. It's far more interesting to create something new than to simply observe nature.
The fact that you had to bring engineering into discussion of your supposed passion shows that deep down below all your layers of insecurities you know it's true.

Can I get /sci's opinion on linguistics?
>>7766350
Parsing human language is kind of a waste of time (at least as far as building UIs go).
The only time it's useful is with search engines or other kinds of web crawlers.

Anything requiring NLP requires some kind of natural language parser.
