"...and a nose of a kingfisher" - except that the kingfisher dives on that video with open mouth. Something's not right here, what's the point of modelling closed one for "no splash"/no soundwave. It's also low pressure -> high pressure in case of the diving bird and high pressure -> low pressure in case of train leaving a tunnel.

  I think they enter the water with a closed mouth and then open it to grab the fish. I see them frequently when I’m kayaking but they are too fast for me to tell which way their mouths are for sure.

Yeah nature got us here, but "here" is a local optimum based on evolutionary selection forces. If you were to design things based on biomimicry rather than first principles, planes would flap their wings, cars would gallop, and computer vision sensors would only perceive visible light. These people are building solutions rather than solving the problem.

  The human brain is the best pattern matcher in existence and we continue to learn from it. Think about that.

  You are assuming that designers would be overly simplistic about their work. Planes don't use their wings for propulsion, so why would a designer try to make them flap? That action isn't solving the same problem, and any engineer would know that. Likewise, tires roll in response to propulsion, whereas galloping legs are providing power. Frankly, the pistons inside an engine ARE closer to a gallop than to a roll. (Well, maybe not in a Wankel rotary engine, but...)

    I think a piston engine is just a different thing than a gallop. A 1 cylinder engine works a lot better than a 1 legged gallop.

    Leonardo da Vinci, notable designer, and many other sophisticated people considered flapping wing aircraft. It’s easy to dismiss it as simplistic hundreds of years later once practical solutions already exist.

      No, flapping wing aircraft simply are less efficent for size scales that can carry a person. That's why the larger a bird's wingspan, the less frequently they flap, such that condors, storks etc. are basically fixed wing gliders. We in the artificial world do have our own local optima with quad copter drones. Flapping here would be more efficient. Consider seagulls that dive and change direction instantly, and can respond to gusts without missing a beat. We have nothing approaching that maneuverability. This is an active area of research.
      - robotresearcher 9y ago
        What do you mean 'no'? It's an empirical fact that very talented designers considered flapping wing flying machines, before they had the information that we have now. They were not 'overly simplistic' except in deep hindsight.

  You seem to misunderstand what biomimicry even is. It’s about identifying root problems and seeing how nature has already solved the same problems we’re trying to solve. The whole concept of first principles is there. Remember when Speedo invented new swimsuits that led to swimmers breaking world records left and right? That was due to biomimicry. Because sharks are fast and shark skin is not smooth under the microscope but instead has lots of tiny protrusions that create micro-turbulence along the surface that leads to less overall drag. And then creating a similar material for swimsuits. That is biomimicry. Not making freaking airplane wings flap to achieve lift. But instead, discovering that the way a hummingbird sweeps it’s wings back and forth creates an area of lower pressure above the wing that virtually sucks the wing up. Interestingly enough airplane wings are shaped in such a way that the wind travels faster above the wing than below the wing, creating a similar pressure difference and achieving lift.

Many of these solutions are about energy minimization. Sometimes its the lifetime energy. Sometimes, its the energy of creation/instantiation. If you start from a bundle of cells you don't have the option to yank a mecanno box of new parts into the system ready-made: you have to use cellular generative methods, to construct largely fluid and jelly filled sacs, which then accrete things, or form surfaces, and you badly want to minimize the energy cost of doing that, within the constraints of the physical system you are in. Whales could be half a mile long and razor. Thin. or globular. They went somewhere inbetween for reasons. Thats what I think, anyway. I base this on (mis) readings of D'Arcy Thompson. 1917. https://en.wikipedia.org/wiki/On_Growth_and_Form https://en.wikipedia.org/wiki/On_Growth_and_Form

I must say, as I enjoy reading about biomimicry. Imitating the environment enhances creativity and brings out great architectural designs if it's well done! These are some interesting information about biomimicry too: https://www.arch2o.com/biomimicry-enhances-architecture/ https://www.arch2o.com/biomimicry-enhances-architecture/
