old man emu Posted January 7 Share Posted January 7 Searching for an answer to the question "What is relative airflow", I came across this site which has short videos on a theory topic that are well created and delivered in an Australian accent. https://flight-club.com.au/ 1 1 Link to post Share on other sites
onetrack Posted January 9 Share Posted January 9 It's an interesting fact that during WW2, and well into the 1960's, both the U.S. military, and Caterpillar, used "comic-book" style training booklets, with colourful picture images, to assist in troop training, and in plant operator training. It was proven that these comic-book style booklets improved students learning rapidly, particularly where large classes were being taught, and where it was impossible to target individual students who needed learning assistance. 1 Link to post Share on other sites

Homo sapiens is the only animal that has been able to take noise making for communication beyond a very basic aid to survival. However, we gain more information about our environment through our eyes, and to a lesser extent smell, touch and hearing. And then there's the old adage, a picture is worth a thousand words.

facthunter Posted January 9 Share Posted January 9 Whales speak to each other over large distances. Here's one for you, OME. How does a flock of birds or a school of fish know how to turn as if they are ONE entity? Nev 1 Link to post Share on other sites
onetrack Posted January 9 Share Posted January 9 (edited) Just like soldiers know when to wheel on the parade ground, when the marker issues the order to wheel. I reckon the flanking marker bird or fish probably makes the call. Edited January 9 by onetrack Link to post Share on other sites
facthunter Posted January 9 Share Posted January 9 Yes then the outer rows open up and the inner ones mark time, but that doesn't happen with fish. They seem to act with one mind. Nev Link to post Share on other sites

Buggered if I know, but I'm not interested enough to research it. However can you give examples of birds, bats and butterflies using sound to discuss the intricacies of how they are able to fly?

Yenn Posted February 8 Share Posted February 8 Somehow birds do teach later generations how to avoid dangerous places. The comic book teaching was used by Stitts in their handbook on covering planes. OME talking about relative airflow could be long winded. 1 Link to post Share on other sites

I think all animals are able to pass on to their offspring a knowledge of the dangers of their environments. It is presumptuous of Man to think than no other animals can reason to some degree.

facthunter Posted February 8 Share Posted February 8 Some examples of man are very deficient in the reasoning department. A lot wouldn't last long in the JUNGLE where if you don't keep your wits about you, you get eaten quickly. . Birds aren't that bright. A big brain needs a lot of food to keep it going .That extra mass means it can't fly long distances. Nev Link to post Share on other sites
onetrack Posted February 8 Share Posted February 8 Quote Birds aren't that bright..... Nev, I've got a bunch of local crows who could prove you wrong on that point, on a regular basis. They might have small brains physically, but they lack nothing when it comes to figuring things out. And I sure wouldn't mind having their eyesight. Link to post Share on other sites
facthunter Posted February 8 Share Posted February 8 As far as Birds go this place here is like Jurassic Park. I'll stick to my thesis. Some birds are too stupid to get away from My wifes zero turn Mower. The foxes make mayhem with them. Most other birds don't like crows. I think they pinch their eggs..

Bruce Tuncks Posted February 8 Share Posted February 8 I reckon birds and fish have a faster reaction time than we do... and the message has less distance to go. I sure agree it looks like they have one mind though. The one thing I am sure of is that this could not be proof of ESP or suchlike. A few years ago, Dick Smith put up a big cash prize for any psychic act. No takers! The terrible thing is that Dick was criticized by "believers". Link to post Share on other sites
