I dropped out this semester.

All this is hypothetical and not homework, but say I had a cannon that shot a projectile at a given velocity. We will call the velocity X. This projectile also has a rocket engine on it and it activates as soon as it is shot. And it has velocity of Y without influence of X. Would the projectile(rocket) gain velocity from the initial velocity X from Y after leaving the cannon.
Example: Projectile leaves cannon at 1000 m/s and on it's own projectile can propel its self at 750 m/s? And let's just throw in this is in a vacuum. I do realize the projectile rocket would have to start and run to it's optimal velocity.
Is 1000 m/s + 750 m/s = 1750 right?
or 1000 m/s?
or 750 m/s?
Or in between?
I know the concept of multistage rockets is they shed most of their mass because that mass was used to store the fuel, but is this the same principle?

Do you scienticians and mathematists have stereotypes for other branches? Like, do physicists make fun of geologists and stuff? What are some of the stereotypes people in your field have of other fields?

Scientific community is full of egoists. Been proved so many times: "If you don't remember how to do certain math challenge you are brainless faggot." <- Like that math challenge proves anything you are arguing about.

If you wanted to understand university math asap (imagine wide main points or the main stumble upons), I want to try it before I go there.

i've been lied to!

Maybe you make them feel stupid and they don't want the embarrassment of telling you how they can't even grasp the basics, they need to save face or admit your better and bow down and worship you as god of science

Or maybe the knowledge of just how vast the rest of the universe is makes them super scared, and they'd rather believe it was all made up, just another religion kind of thing

Also, Ideocracy

Also, I think we will have to cull them one day

Bernoulli's principle sates that the internal pressure of a fluid or gas is inversely proportional to the velocity

basically the faster a gas is moving the lower pressure it will exert

the wing moves at a constant speed and the distance from the front of a wing to the end of the wing remains constant

what happens is the air travelling along the bottom of the wing can go straight to the other side

but the air on the top must travel up over and along the top of the wing.

the air at the top and the bottom do this in the same time as its the wing moving

the top air travels a further distance in shorter time = higher velocity

higher velocity = lower pressure

the air on the top has a lower pressure because of the shape of the wing, low pressure systems suck and the higher pressure air at the bottom pushes, creating an upwards net force

ultimately pushing the air craft up

pic unrelated but cool, it transforms continuous motion into discrete motion

OP I think I have a better one

does anyone know a good site for finding original sources of ww2 documents?

So are there "scientific keyboards"?

I'm kind of tired to having to resort to ASCII codes or a char map to input Pi, Theta, the partial derivative curly and all the others

Pic unrelated, although pretty cool

They all be mad jelly
i mean look at this
fuckin genius

/sci/, are there any machines that create more energy than what you put in? I don't care how small the return is, or how impractical the machine is for whatever reason.

or this animooteds

More of these.

Hey /sci/
Got any /sci/ related hobbies?
I like to perform various chemical experiments, and design small objects.

also, what are things that /sci/ believe should have a quick fix, yet one does not exist?
I just designed a recepticle for my whiteboard eraser (a soft square of slightly plush material, about 22cmx22cm) because it kept falling off the hook because it is quite soft.
I feel the need to invent things all the time, so I bought a glass desk, so I can write on it with white board marker. What is your workspace for science like?
Picture is related, its the kind of thing I wish I invented.
