That's amazing. Ur knowledge and understanding and breakdown of the flight of a fly is truly important. Thanks for your contribution buddy. U the man. Someday we can harness this secret to reduce the energy we need to achieve flight with wings...
Amazing. Lots of extremely elaborate fields of science overlap in this small, but complex creature. Explaining all of that in a three-series lecture is highly acknowledgeable. However, I find believing that all this beautifulness came together (to give a functional insect) from random leaps unscientific.
Lift by way of an airfoil, wing, is NOT due to Bernoulli. It’s Newtonian. However, the Bernoulli equations are close enough to what does generate lift that they are used to design airfoils. Lift by an airfoil is due to the extreme vacuum on its top-back surface pulling downwards the air flowing in over it. This downward pulled air then pulls down more air from above it. All of this air is then accelerated downwards at the airfoil’s trailing edge. The opposite an equal action is lift. Interesting fact: As airfoil induced lift is Newtonian, most of the energy that sustains a plane in flight comes from gravity. That is why aircraft have unpowered glide ratios, and why autogyros are able to fly.
Seeing is believing! Without those gadgets & tools to capture what's going on, works by those pioneers are simply amazing! Moving wings are nasty one to study. In comparison, how simple & beautiful is wing stroke of birds (except hummingbirds) & bats (maybe of pterosaurs, too)!
I bet the vortices and such are what makes the wing motion audible, as they represent major changes in air movement as the wing moves at frequencies above 20 Hz.
Think of it more like swimming than flying maybe. Imagine you moved your palm through a still pond, and saw the vortexes behind the edges of your palm.
Also a correction..at ariund 7:00 why is the force of the wing on air pointing up above the wing..he is discussing the force of the wing pushing DOWN on air BELOW the wing..so the arrow should be pointing down and below the wing?
I assume for the fly it's happening because of the high angle of attack (angle of the wing into the oncoming air). The air 'tries' to remain stuck to the wing top surface, but the angle is too steep, so the air 'detaches'. Since it is no longer attached, and there is slower/still air above it, it forced/sucked down and backwards into the vacuum behind the wing upper surface, and eventually comes into contact with the 'next' 'batch' of detached air. Round and round it goes, in a 'vortex'. To understand vortexes it may be easier to watch videos on wing stalling, turbulant flow, or eddy currents. The funny thing is that for aerodynamics in school/university detached flow and the resultant wing stall was a disaster! Incredible that insects can harness it to make lift. For understanding how leading edge vortexes make lift, that's another things that's a bit tricky, I'm not sure I completely get it.
In your TED Talk you said you captured the data of flight directly from the fly tapping into its brain. Would it be possible to capture all the movements or patterns of the fly and convert it to a set of commands to control a self flying device such as a drone? I guess my question is how basic or vast is the data captured when in flight?
At 1:53, Awesome compound eyes having a cluster of photoreceptors receiving information as different wavelengths about another fly spatial position and bang !! Let me go supersonic haha
Beautiful work very well presented. I recommend all three lectures.
I watched your Ted talk (online), glad your elaborating further on this subject
Thank you so much for this series! This is such an important topic

Wonderful. Makes promises miself study this aerodinamics and bugs fly deeper in the future. Thanks for your work

Mr dickinson your are ahead of you time, and very intresting guy and i would like to see defferantial equation on this topic,thank you❤

Very educational. Thank you !
Fascinating, thank you! Definitely putting them back outside in jars now... if I can catch them.

Amazing video! I love science like this. Nature is fascinating!
If it wasn’t for you I wouldn’t have known how amazing bug wings really are.
thanks for this good lecture, good introduction for me to know how bugs fly.
may I explain it in Indonesian language or another presentation for children's learning in Indonesia
thank you for the educational info
Now i remember boats in southeast Asia are manually pushed agitating rudder as the fly wings in your video. Could be?
It was a good talk, but can someone please write down, in layperson's language, what exactly is a leading edge vortex and how a fly wing generates it?

Fascinating!
How this swirling helps generate more lift? What law of aerodynamic applies here?
my question is simple: is there mathematical model to simulate fly movement ? thanks..
Holiest of cows! Glad to know that science never stops trying to figure things out
Brilliant!!!
subtle memes in a presentation. I love it

It starts with Physics not so much Biology 😂
How so?
@@10000daddy How could it not be?
Biomechanics, it's all about physics and engineering
Very interesting and nice work, well done. I agree with all but this is not due to evolution, this is evidence of God's work and wonder.
This guy likes fly’s huh¿.
