I think they're forgetting one crucial part: engagement. If something matches your "learning style" - you'll be more engaged in that content - therefore you'll more likely to pay attention and try to remember what is happening. Forget learning styles or what-not biggest question an educator has to ask is how do we engage the children we're teaching? How do we get them to think about the subjects we are teaching? The confirmation bias thing is nothing new btw. We should all be aware of it. Alas, it's like Dunning Kruger effect where people who know about it are too aware of it and we have no hop for people who are unaware of it.

You know the downwind faster than wind thing? Yeah I know it's a never ending topic but it is one of the most of the most interesting physics things on UZcrone. Why I mention it is because I saw a video where instead of a treadmill they used a rotating circular plywood "turntable" and the "cart" was a single wheel unit that ran around the outer edge of the turntable while being tethered to the center. The interesting thing is that, although the table was turning at constant speed, at first the cart was pulled along with it in the same direction but gradually slowed down and eventually reversed direction as the prop sped up. How could the prop gain speed if the table was always at the same rpm? Was the wheel slipping some at first? I don't know what the explanation is. At least the turntable arrangement is something people can actually make at home, looked like a bicycle wheel with a plywood circle attached. Going to a treadmill store is little less convenient. The video title is "DDWFTTW - Turntable at slow speed?.

Greetings. I just got to know something very difficult to imagine. Can u please explain it intuitively. . If I have a container, equally divided by a wall, such that one half of container has air and other is empty space or vacuum. The situation here is completely ideal or there is no friction in the walls of container and there is no loss of energy while any collision to be specific. So, when I remove the wall, the stack community says that the air does not get evenly distributed but instead it enters the second region (which was vacuum before) and now the first region has become vacuum. Please explain because I dont believe it.

Thanks for sharing this. I used to do presentations on education, wherein I talked about various aspects of teaching. I've never heard of VARK, but sensory preferences (VAKOG or VAKTOG if you want to add tactile as separate from kinesthetic) was one thing I discussed in the same sense that you're talking about - multiple senses need to be stimulated to improve the chance of not just remembering but also understanding and applying. I also brought into the mix other things, such as humor, WBT, aspects of Montessori & Waldorf, personality differences, the use of certain psychometric tools, multiple intelligences (and noted the flaws in that theory), EQ, etc. There was a lot more to my presentations than just that, of course, but I'm glad to see you fighting the myth that one sensory modality is a good idea. I wish that the associative style of memorizing (memory masters) was taught in school, and I firmly believe that sign language should be integrated starting in pre-primary. I also wish that more real-life skills were taught on an ongoing basis because it sure seems like education (in general) is still doing the same thing it was designed to do all those years ago: create workers and prepare you for MORE education. The only sense of relief I have in American education is that they don't force everyone to study everything all the way up to physics, for example. As a system to help people become entrepreneurs and excel, however, education in most countries is pathetic.

So the downwind wind speed is irrelevant, as you could make this work on a still day, so long as you towed the craft up to enough speed (relative to ground zero), in order for the wheel-to-prop lever/pulley system to gain momentum, correct? Isn't that why the models work on a treadmill? However, the treadmill supplies continuous kinetic energy to the wheels, so wind is needed with the full sized prop to self start & get up to wind speed before it can accelerate past it? So what's the theoretical maximum speed ratio then, relative to wind speed + drag/friction? It can't accelerate forever, as that would really be perpetual motion then! The entire experiment is actually misleading then, as you are not actually using just tail wind power to push the craft down wind faster than the wind. In fact, the main power source is the prop turning the back wheels only through initial wind impetus & the pressure differential across the blades, which is then almost immediately switched to pulley/lever self drive fan mode. I therefore find the entire experiment to be scientifically misleading & somewhat disingenuous, given the initial statement about it using 'only wind power'. If I was the physics professor I would feel slightly conned, kinda like I was tricked using bait & switch tactics, or slight of hand...
