True or false?

False since bees do fly and false since science never made such a
claim.

Bees cannot fly anymore than a helicopter or a parachute can fly.
Bees hover.

The definition of hover <snip to arrogantly ignore what you say>.

Rockets fly straight forward. Bees are not rockets. Parachutists move
"forward".

<snip to arrogantly ignore what you say>

So please give me a definition of "hover",
<snip to arrogantly ignore what you say>

Only if you give me your definition of "forward", "up", "grew up", "position",
"took off". How do you give or take an "off"?

You've made my point. One can make correct yet seemingly incorrect
statements by careful choice of words. You expect me to understand
the jargon of "took off", yet a rocket's take off is vertical, a plane's take
off is horizontal. I'm supposed to understand what you mean, but
you are not required to understand what I mean when I say a rocket
cannot fly, it has no wings, but it certainly moves "forward".
Is that how it works?
"Take off" is a cliche, jargon. In the context of a plane it
implies horizonal motion, in the context of a rocket it means
vertical motion, and we use "lift off". Yet wings lift a plane "off".


There may have been a theory that was Falsified but that is what
science is about.

You haven't falsified anything. A bee cannot fly, its body mass to
wing
area ratio is too high. What you did was used your definition of
"flight"
(hover, buzzzzz) which differed from my definition (glide with fixed
wing).

When I was 10-years-old I got my first bicycle and it had 3 gears.
On the second day of owning this glorious machine, experience had
quickly taught me that it was easier to pedal in low gear, so when I
saw Goodearl riding home from the shops one day I decided to race
him (without telling him, he had a head start) so I tore after him in
low gear, pedalling furiously.
Goodearl won, I couldn't catch him and Goodearl didn't have any gears.
So... on my way back to my home, crestfallen, I thought I'd try out
the high gear, perhaps it had a purpose. It was much harder to pedal,
but boy-o-boy, was I going fast.
I decided not to race Goodearl again. I'd learned my lesson, I could
go faster than he could, but I'd have to work for it.
Five years later I dated his sister Janet. That was more fun than racing
bicycles.

Then I got to 13-years-old and needed a bigger bicycle. With 10 gears
and lights. My dad had a generator on his, I wanted one.
By then I knew all about electric motors, I'd taken my trainset apart.
So, thought I, why not drive a motor from the generator?
Perpetual motion doesn't work for the same reason I couldn't
outrace Goodearl, turning a generator is hard work and gear ratios
do not help.

But don't take my word for it. Experience is the best teacher, go ahead
and bolt a car starter motor and a generator on your bicycle. I'm sure
there are plenty to be found in junk yards. You can even leave out
the bicycle, couple the motor directly to the generator, give it a spin
to start with and have free light in your home. If that doesn't work,
put a gear between them and spin the generator twice as fast as the
motor. If that doesn't work, try outracing Goodearl, he has no gears.

Very good. The language of science is mathematics, not English.
English is vague.
