It's a physics seminar at this point. Teachers are above the line, students below.

No, he's that guy in the algebra I class who's bringing up the impact of infinite multidimensional vector spaces and their impact on theoretical astrophysics.

So, he must be one of those guys that have those books on the actual science of Star Trek and Star Wars, with blueprints and everything?

You have a problem with Enterprise Technical manuals?

No, not necessarily.

Just the people who buy into that rubbish.

the enterprise could never make the kessel run in 12 parsecs.

how else am I supposed to figure out the right plasma flow rate into the dilithium chamber?

I hear only the Milennium Falcon could do that.


They should make a movie just about the kessel run.

UBERGEEK RESPONSE:

Considering that a parsec is a unit of distance rather than time, any space craft would travel the same distance.

anything the millennium falcon can do, the enterprise can do better.

EVERYONE knows that you don't put plasma in a dilithium chamber.
That's where the photon torpedoes go.

gotta love wiki

quote:

The most famous use (or misuse) is from Star Wars: A New Hope. In the Mos Eisley Cantina, Han Solo refers to the Millennium Falcon as "the ship that made the Kessel Run in less than 12 parsecs". It is not clear whether the unit is being used to measure time or distance in this context. However, later novels in this fictional universe attributed this claim to the ability of the Millennium Falcon to reach the planet Kessel in the shortest distance despite having to pass near a very dangerous region of space

Right... damn my flying time is all gone to waste. Sucks that I just don't have any comprehension of how a plane flies.



What is an airfoil?
An airplane wing has a special shape called an airfoil.

As a wing moves through air, the air is split and passes above and below the wing. The wing’s upper surface is shaped so the air rushing over the top speeds up and stretches out. This decreases the air pressure above the wing. The air flowing below the wing moves in a straighter line, so its speed and air pressure remain the same.

Since high air pressure always moves toward low air pressure, the air below the wing pushes upward toward the air above the wing. The wing is in the middle, and the whole wing is “lifted.” The faster an airplane moves, the more lift there is. And when the force of lift is greater than the force of gravity, the airplane is able to fly.

So.....the Milennium Falcon flew in a straighter line than other ships?

You're just not getting the fact that the treadmill is inconsequential, since the engines are pushing against the air, and not the ground.

eta: For the record, if (and that is a BIG if), the experiment is run properly, the plane should take off.


Are you joking?

"Take off speed" is the forward speed of the aircraft necessary to generate LIFT. There has th be airflow over (and under) the wings/control surfaces for the plane to take off. If the plane is sitting on a conveyor belt that is allowing the WHEELS to move at take off speed, that does not mean a thing. There is no movement of air; therefore, the belt could be going 250 mph, and the plane will never get off the belt.
