A Quantum Swimmer Never Gets Tired
By Adrian Cho
ScienceNOW Daily News
24 February 2006
If you're ever shrunk to nano-scale and chilled to
near absolute zero, take solace in this fact:
Swimming may be a whole lot easier. A team of
mathematical physicists has calculated that
miniscule robots swimming in a frigid quantum fluid
can propel themselves without losing energy.
Theorists have pondered the idea of
