No it fucking wasn't you stupid fuck.
He was fired a couple years later because he was a kiddy fiddler. Meanwhile I'm becoming an engineer.

the array IS wrong

Bad thread.

So far it's just the anons posting the stories that are retarded

>Meanwhile I'm becoming an engineer.
My condoleances

Wow, how did that detail escape me for so many years? What the fuck? I am shocked

It's not too bad, you just have to stay on your toes, or rather knees, and keep up with the cock sucking exercises.

At least some children suffered in this dumb story

It's a shame since English is usually a really fun class that takes no effort anyway.

What I did not appriciate, as some seem to have related with their stories, were the teachers who couldn't acknowledge that they were wrong. Seemed like such a stupid thing to not do just to assert your power and supperiority, which i assumed they otherwise would feel be undermined. Don't have a specific science class example our teacher in religion (yes we have that here) in religion made a statement about the history of christianity or something that was factually wrong, and when i pointed it out in a non-dick way he hade a semi huge fit. Didn't take the agurment because it was abviously important to him that his authority wasn't undermined eventhough he probably knew he was wrong or got insecure.

I once had a teacher that said the Philippines was a member of the Soviet Union.

She was a nice teacher but sometimes she says things like this and we just keep quiet and smile.

what? how the fuck did they want you to show your work then?

It was, briefly

She was right and you are ignorant

>we just keep quiet and smile

It's sideways :^)

quite a few stories:

> Be 17, kick out of school because noise bomb (joke got out of hand)
> Had to be at a crappy place for the rest of the last school year.
> "Physics" teacher is discussing inertia.
> Suddenly starts claiming that to bodies accelerate at different rate.
> I am "the fuck?", "Sorry prof, but Galileo showed that that's not true"
> The idiot laughs. "You know, a rock hits you harder than a rubber ball"
> "You are confusing how hard is an object with how fast it hits you"
> Starts laughing "I am an engineer, you know."

Yeah, you are an engineer, that has to give physics classes in a shitty school. The idiot even complained to the Principal, who called me. I had to explain who fucking Galileo was!

if you want more stories, just ask

but an electron isn't matter, matter mus have Protens and ElEcTrOnS, maybe even sum neutraltons as too.

Idiot, Protons are what make big muscles mass, and E equals m c ■ so photons are what I post on Instagram

actually nothing has mass because everything is made of quarks which are point particles :^)))

Teacher thought you listened when he explained what you were supposed to do.
Teacher thought you were watching as he made several examples on the blackboard.
Teacher thought you understood when he asked if there were any questions and you said nothing.

He was right in not bothering to explain it once more at that point.

no

>they tortured the poem

That is a metaphor. Nigga, I am studying mathematics and I don't even respect literature and yet I know more than you about it,

You guys may not believe this but my physics teacher in high school was basically autistic, she asked me and my friend how to cross multiply the time dilation equation. Any type of physics question you asked her she would avoid it then ramble on about something else. Still the worst teacher i have had to this day.

Fuck I hated that cunt.

This sounds like you modeled the moon to spin on it's own axis when the moon is tidally locked.

at least biology class was cool

It still spins on its axis though doesn't it?

No, it's stuck always showing the same side to the earth. It does not spin at all.

Yes, it spins almost in sync with its trip around the earth, which makes it seem like the moon is not spinning.

omg....
if it didnt spin then we would see all sides of the moon you moron.
Its rotational period is the same as its orbit around the Earth which is why we only see one side. An object which spins at the same speed as its orbit is tidally locked but it still spins on its axis.

whoops

its ok, here have a moon.

Since the earth is flat, is the moon flat as well ?

It's electron, dunceton

it's a hologram bro

Holy fuck that image triggers me.
You can tell the stupid bitch is just looking at the solutions manual, and has no fucking clue how to do basic math. The pink ink is fucking obnoxious.

but is it a 2D hologram ?

I want to point out that he was actually a great professor but I'm just still mad as a fuck about this.

Doesn't matter when you are some of the few with cash on hand in the age of poor

This isn't real, it's far too stupid

You're partially correct and you're teacher is terrible for not explaining that

Bro you were totally cucked by your teacher

Do tell

what this guy saidIt would only be a personification if the poem was torturing somebody, because you are giving him human abilities or 'personificating' it

Fuck off m8, people like you are the reason everyone thinks engies are only in it for the money.
I love my field, I love implementing existing shit into new systems and coming up with workarounds when, not if, nothing works. I love inventing new stuff.
And I sure as hell enjoy sucking cock.

An electron is not matter since it doesn't have a volume.

Needless to say the professor was flabbergasted. I dropped that class the next day. I find it hard to believe any biologist knows what the fuck they're talking about - particularly given the quality of their professors.

I bet you felt euphoric after that moment. Not because of some phony scientist's shared knowledge. But because you are enlightened by your intelligence.

nice b8 m8

Quality post.

This has to be bait.

You're an idiot. Electrons are much smaller than protons.

Kek

>Electrons have no volume
Vs.
>We approximate electrons as point particles because their volume is insignificant error.

I bet you think gases actually obey the Ideal gas law too.

your teacher most definitley has a master's in english, but has no business being a teacher, because that is a completley understandable mistake that should've been explained to you

How were you supposed to represent it?

Why didn't you just tell the fuck to clean it or be reported? It's not like he knows what your position entails exactly.

t. Goodell

I guess shading the 3/4, not the other way

By high school I had already learned that all those answers are wrong.

What the fuck is with your education system?

only teaching people "what they need to know" and then making them unlearn it as soon as they have interest in the subject and want to continue it

this is bait because >"w-what do you mean?"

however this is related and an interesting watch
youtube.com/watch?v=rNuEBngivKU

tl;dr people who receive hardcore private religious schooling in US don't simply ignore everything thats in science books. They receive special 'science' books that contain misinformation. Their entire lives they are never confronted with people that have a different viewpoint. Only in the moment that they appear on the bill o'reilley show they for the first time hear somebody say something that doesn't fit their world view, and are convinced that the entirely of the scientific community has young earth creationists in every country that all purport that the earth is 6000 years old. Which is why 'your facts aren't true go read books' doesn't work on them since they believe the books support them.

This is why it disgusts me that my university offers both science degrees and teaching degrees.

The equivalent for my mathematics degree at the education faculty takes the equivalent of calculus one in the 5th semester. It is truly a disgrace.

However, I am not surprised. There is obviously a cancerous culture that pretends like teaching is easy and anyone can do it well, which is why staff is barely ever fired for bullshit like what you describe.

This is some top tier bait. Good job user.
