Insultingly Stupid Movie Physics

Rather than duplicate a thread, I'm just posting a link to this thread in the Arts/ Film forum.

The worst one I've seen for science is hollow man.

For a start, if he was really invisible, he'd be blind!

I seem to recall a film where one scene showed a submarine getting bashed from sinking blocks if ice . WTF, loike?

Onlookers at crash sites are often so concerned about explosions that they unnecessarily jeopardize a person with a spinal injury by pulling them out of a wrecked car. The common Hollywood depiction fuels these harmful misconceptions.

:rolleyes: :rolleyes: :rolleyes:

Good site, though!

Ok .. the space ship is just about to decelerate to a speed at which it can orbit Mars. But the rocket motor blows up. As luck would have it the resupply module is on an intercept course and will pass within 1Km of where they are.

Rather than detach the lander (which has enough umph to make from the surface into orbit) then kick off from the doomed space ship towards the suply module.

so the question - how fast did they jump ?

It's not clear if they were still on the hoffman transfer orbit
- if they were then doing nothing would have transferred them back to a point on earths orbit - though the spaceship rentered very soon afterwards -
(the plot said earlier they were going to use extra fuel to speed it up - so probably even higher speed)

All I'll say is "inertial dampers". handy way of dealing with the problem.

GuanYin

sorta like

"Heisenberg compensators" :rolleyes:

dudara

sweep all the nasty physics into a handy title. make it sound good without ever having to explain it.

Capt'n Midnight

Sounds like every episode of voyager

PS. beaming down - was originally concieved 'cos they couldn't do the special effects of spaceship landing back in the 60's - it then became a plot device - to quite litterly dump you in the deep end..

Bones "Jim, just for once can't we find some aliens that don't disable out phasers"

Movie Physics - a 50Kg woman will always be able to beat a 100Kg man in a KungFu fight

dudara

because she's foxy and girl powered. What they don't teach you in martial arts classes, is that you should wear leather trousers and stiletto boots. only then will you be able to beat the 100 kg man.

The best movie cover-up, even though it doesn't involve physics, is infecting the alien spaceship in "Indepenence Day" with the computer virus. Written on an Apple Mac to boot.

Stark

Charlies Angels. Then again the stupid physics were deliberate.

Apple Mac, 9/10 interstellar conquerers perfer it.

lol

Firstly dud, shush.
Secondly, mmmmmm Happy Place
Thirdly, didn't you ever watch Elvira or Single White Female? Stilettos are dangerous!

Independence day
Aliens must use M$ - how else can you explain the speed and virulance of the infection..

Seriously it's likely that they would not be running any AV or packet scanners- given the fact they are telepathic any alien virus writer would last about 30 seconds before getting a slap on the wrists..

Still Like Bab5 - humans have no artificial gravity and if you want to go to a planet you need a shuttle with wings

Anyone ever see "the ice pirates" ?

The car crash in commando - no seat belts / convertable / telegraph post - the car is totaled and Arnie and Co. just hop out.

Stark

And of course the fact that the magnet should have stripped the iron right out of the happy couples blood, let's not forget that.

Kudos for X-men 2 though for doing that in the film. I was thinking at the start "couldn't magneto escape by sucking the iron out of the guard's blood", "oh cool he did "

No actual film to quote but ive seen enough of childrens programes/cartoons to get upset about the idea of x-ray specs seeing through peoples clothes to allow a pervy teenager to leer at curvy women.

dudara

I remember being in lab in Queens where they had this mother of a magnet, something like 7 Tesla strength. There was a red line on the floor around it, a few metres in diameter, and anyone with a heart complaint wasn't allowed inside that circle.

RE: liquid magnets - look up Curie (as in Madame) temperature - AFAIAA no true liquid exhibits magnetic attraction. (suspensions are not liquids) - one type of thermostat uses this property the sensor is only attracted to a magnet below it's Curie temperature (note it you heat the magnet up beyond it's CT it will become demagnetised)

Note: most salts / organometalic compounds are not magnetic - Metalic oxides being a major exception to that rule

"The susceptibilities of paramagnetic substances are small and positive" - or in english if you have a strong enough magnet field you can generate a repulsive force on many non-metalic materials. The best demonstration is the live frog levitated, which leads on to -
RE: Heart condition - I suspect that's to do with pacemakers (or maybe valves) because very strong static magnetic fields have not been shown to have any harmful effect.

Magnetic terms.
http://www.mines.edu/fs_home/tboyd/GP311/MODULES/MAG/NOTES/typesmag.html

Here are the Curie temperatures for five ferromagnetic elements: cobalt=1,130 degrees C
iron=770 degrees C (eg: picking up a magnet with a red hot poker)
nickel=358 degrees C
gadolinium=16 degrees C
dysprosium=-188 degrees C

I know yeah. "Excuse me, could you stand behind the x-ray generator so my x-ray specs can pick up the image of your bones, which should be close enough to what you look like exactly between your clothes and your skin". :rolleyes:
