Teach me something/I teach you something thread. - The thread where we all feel smart because we have an autistic level of knowledge about some niche subject and feel like giving a watered down lecture on the topic despite like half of everyone already knowing this shit.

Basically just vomit out some interesting obscura and talk about how cool it is we know that or how autistic we are for studying it:

Ever wonder how protons can stick together in an atom's nucleus? There's literally 20lbs of force trying to rip them apart due to the electromagnetic force. At that small of a scale, that's massive. Turns out neutrons are the key (or part of it). It all has to do with quantum chromodynamics.
As most of you probably know: protons an neutrons are composite particles made of quarks and gluons. I'm not gonna waste time discussing the particulars of the standard model of particle physics, so what I just said is all you really need to know about that. These quarks are bound together via gluon exchange in basically the same way a covalent bond works in a molecule. The "trading" of bound particles between composite particles binds them together with considerable force.
This basic concept applies outside a given nucleon in that a quark will try to "escape" its triplet. The energy required to do so results in a quark/antiquark pair called a meson. These get transferred between nucleons, thus binding them together, again, in the same basic fashion that covalent bonds work. The range of this process is very limited and this is pretty much why nuclear radiation happens.
Too many protons and a lack of neutrons means the electromagnetic force overtakes the nuclear force and it falls apart. Too large of a nucleus and the effective range of the nuclear force is exceeded and the whole structure is unstable. Too many neutrons with a lack of protons results in another form of radiation due to the weak force.
The weak force is like the autistic redheaded stepchild you keep in the basement. He does a lot of weird shit no one fully understands so if he starts making noise you're best just ignoring him. He's got tendies. He's got LEGOs. He's fine.

This is the proper way to gesture for someone to fellate you. Pay special attention to how the wrists intersect just above the hips, NOT at the groin. A lot of people get this part wrong, but it's all in the wrists, just like basketball. You're going to want to repeat this motion quickly about three or four times for maximum effectiveness.

The hypertext transfer protocol operates on top of the TCP layer. Requests are comprised of a header section and an optional body. The headers are comprised of lines of ASCII-encoded text, separated by carriage return and line break characters (CRLF, or 0x0D 0x0A; hereafter the line break sequence). The first line will be the protocol and version, the HTTP request type ("verb"), and the path to the requested resource; e.g. "HTTP/1.1 GET /index.html". Other headers have a label (with no spaces) followed by a column, a space, and a value for the header; e.g. "Accept: application/json". Multiple header values with the same label may be used. Two line break sequences separate the headers from the request body.

HTTP responses are formatted similarly, with header and body sections.

Famous baroque painter Caravaggio was actually a violent cunt. When he was not painting he was boozing, being a public menace and getting into street fights. Caravaggio actually killed a dude in a fight and had to flee Naples before they could hang him for it. He eventually got a papal pardon but he continued being an antisocial cunt right up to his death. Same guy that painted this



Spanish painter Francisco de Goya charged and extra fee for each hand that he had to paint. So now you know, when you see one of his portraits if the subject is hiding his hands its because they were being cheap



There's two versions of the comic Dennis the Menace, one american and one brittish. Both released simultaneusly starting on march 1951 and despite the same name and similar concept both were made by different creators who had nothing to do with each other, the two comics are independent ips and not related at all.

The British Rail Class 185 is a 3 car regional Diesel Multiple Unit with a 750 horsepower engine under each carriage, meaning they have the same power output as a type 4 locomotive. One allegedly hit a speed of 125mph during testing, despite having the aerodynamic properties of a brick. Because of this, 3 out of the 7 power notches on the controller are locked off to save on fuel and component life, as well as having the ability to switch off engines when in service to reduce fuel usage and emissions.

They also sound great.
