歌中的天梯不是上牙膛吧,俺觉得应该是Space Elevator
天梯,又译空间电梯 (Space Elevator),是一种低成本将有效载荷从地球或其它星球
的表面运输到空间的解决方案。这个方案旨在建造一部称作天梯的运输工具。
http://en.wikipedia.org/wiki/Space_elevator
With a space elevator, materials might be sent into orbit at a fraction of
the current cost. As of 2000, conventional rocket designs cost about $11,000
per kilogram for transfer to low earth or geostationary orbit.Current
proposals envision payload prices starting as low as $220 per kilogram.

OP said male Chinese in America have IQ advantage over Americans, a true
statement.
Mr. guichidai the idiota/ignoramus first rejected the statement as "
assumption", practically denying the measuring standards behind this "

When pointed out such absurdity, mr. guichidai, or shall we say chidai,

After you jump, the elevator will undergo a harmonic oscillation (if
assuming the simplest spring-mass system and ignoring dumping). The tension
in the cable (which hangs the elevator) also oscillates, and thus there's NO
steady reading of "weight" of the elevator.

Hi all
DO NOT use elevator # 3 (south side of building). A person was traveling
down and the elevator dropped so fast that it took him off his feet!! I
have contacted the Phys Plant. I will put a note on all the floors not to
use this elevator until it is fixed!

哦,实际上电梯都安了大弹簧:
http://science.howstuffworks.com/science-vs-myth/everyday-myths
空气弹簧:
But two things would cushion the blow. First, the elevator car would
compress the air at the bottom of the shaft as it fell, just as a piston
compresses air in a bicycle pump. The air pressure would slow the elevator
car down.
机械大弹簧:
Second, most cable elevators have a built-in shock absorber at the bottom of
the shaft -- typically a piston in an oil-filled cylinder. That would
cushion the impact too.
