quantum mechanics

iℏ⋅(∂Ψ(x,t))/(∂t)=-ℏ^2/2m⋅(∂^2Ψ(x,t))/(∂x^2)

(This is how the average conversation about quantum mechanics generally goes:)

Person 1: Omg like literally iℏ⋅(∂Ψ(x,t))/(∂t)=-ℏ^2/2m⋅(∂^2Ψ(x,t))/(∂x^2)
Person 2: Right! Lmao it's just ∂Ψ(x,t)=Ae^(i(kx-ωt))
Person 1: Exactly! And iℏ⋅(∂Ψ(x,t))/(∂t)=iℏ⋅(∂Ae^(i(kx-ωt)))/(∂t)=ℏωAe^(i(kx-ωt))
Person 2: Hahaha! -ℏ^2/2m⋅(∂^2Ψ(x,t))/(∂x^2)=-ℏ^2/2m⋅(∂^2Ae^(i(kx-ωt)))/(∂x^2)
Person 1: Yeah and it's like -(ikℏ^2)/2m⋅(∂Ae^(i(kx-ωt)))/(∂x)=-ℏ^2/2m⋅(∂^2Ψ(x,t))/(∂x^2)=-ℏ^2/2m⋅(∂^2Ae^(i(kx-ωt)))/(∂x^2)
Person 2: Bro I was thinking the same thing, as soon as she walked in my mind just went (ℏ^2⋅k^2)/2m⋅Ae^(i(kx-ωt))= -(ikℏ^2)/2m⋅(∂Ae^(i(kx-ωt)))/(∂x)=-ℏ^2/2m⋅(∂^2Ψ(x,t))/(∂x^2)=-ℏ^2/2m⋅(∂^2Ae^(i(kx-ωt)))/(∂x^2)
Person 1: Pfffftttt!!! (ℏ^2⋅k^2)/2m=ℏω
Person 2: Lol yeah man, great shit right there... So anyway, how's Jack?

mechanically agitated

Hit hard with a blunt object.

My car wouldn't start until I mechanically agitated it.

mechanic door

To stick your thumb in a butt hole in a clockwise motion than proceed to pull out in a counter clockwise motion.

Bobby and I were getting bored watching Joe dirt 2 until he mechanic doored me back to reality.

Mechanical Pencil

When wood pencils just aren’t enough. These became popular roughly in the 2nd grade, kids would screech over these. A long thin piece of graphite, commonly found in the 0.3 to 0.9mm range. Finding one of these on the floor, especially when there is a lot of led inside of it is a status symbol of clout and wealth within the school walls. Kids will also cry when they loose one. Consider it your lucky day if you find a loaded mechanical pencil on the floor. You can buy a few pencils for one if you’re lucky! These are the best writing tools you can get access to, and since no one buys them, it may take a while to get one.

Kid: Dude, I just found a loaded mechanical pencil.
Other kid: How much led is inside?
Kid: 4 full sticks bro.
Other kid: Lucky! Toss me one?
Kid: Gonna cost you some cash brother.

mechanical diarrhea

A mess of old mechanical items and parts from various machines like automobiles, computers, appliances, and other things found in junkyards.

Look at this mechanical diarrhea on the ground!
