by Jeanette Cain Conquering gravity, floating and levitation is
becoming more of a reality and less likely good science fiction
reading. Ning Li at the University of Alabama, works on a device
in the laboratory that she believes will one day change the
world. Since Newton's famous apple story, the majority have
believed that gravity cannot be conquered. Li's laboratory
contains tanks of liquid nitrogen, a temperature chamber that is
390 degrees below zero, and a spinning ceramic material disk on
the inside of the chamber. The disk is being levitated by
powerful magnets and, if you were to see it, you would see that
it floats inside the chamber. Ning Li's hopes are to invent a
practical anti-gravity device allowing rockets to blast off
without propellant and power plants to operate without fuel. She
even hopes to design an anti-gravity car within a decade. Li
does not consider herself a normal scientist and neither does
NASA. NASA helps by funding some of her research on the gravity
