发帖数: 10018 | 1 A few years ago a group of scientists developed an interest in bumblebees.
These scientists reckoned that these little insects held some secrets of
flight that may provide some answers to questions about operating in space.
After all, they asked, how could such small wings produce efficient lift for
a relatively large and hairy torso? And how could a round body and flight
position that violated many principles of aerodynamics move so efficiently
through the air?

Bumblebee(大黄蜂,熊蜂)不适合飞行只是1934年一个空气动力砖家用了错误的假设，得出的错误
的结论。多年来演变成熊蜂相信自己，创造科学奇迹的故事。
