Mystery "solved": how honeybees fly |
Scientists found in the 1930s that they couldn't explain how bees
fly, and it has remained somewhat of a puzzle until recently.

I daresay the same stupid people can't figure out how a helicopter
flies either, it's got no wings.
Grow up.

WRONG.
Helicopter rotates its wings.
Turtles have no wings, but they can fly if you throw them, it is the shape
that is important.

It was never precisely a "mystery" why bees are able to fly. The
much quoted incident of discovering their supposed unflyability had to
do with a very rough calculation, on a moment's notice, of lift vs wing
area. It was always understood between then & now that the total lift
is generated by powerful wing strokes. Indeed, anyone who spends time
outdoors can see that bees hover a great deal of their time, which
means that lift is being generated by a mechanism other than simple
laminar air flow from front to back, as with an airplane wing.

I have a picture showing a bee can lift more than its own weight. Its
body is big,and its wings are short,but its can move them very fast.
Naturally my way of taking pictures can stop the movement of their
wings. Reality is they don't flap their wings up and down. I took these
pictures of them 50 years ago. That's just about how far I'm ahead of
Google at this spacetime. Bert
