Dan Gelbart is the finest example you’ll find of someone who blends fundamental theory with practical application. If you want a definition of what a true “Engineer” is, it’s him.

Good job KZitem algorithm. I love me some more Dan Gelbart. Edit: That was an excellent presentation. I was especially awed by how Dan handled the student's guess regarding the lens question. When confronted with a 'solution' that isn't inline with the answer book, most teachers would just say it was wrong. Yet Dan has so much insight into his expertise he was still able to explain why mirrors aren't the solution with excruciating detail all without being pretentious. Can't wait to hear more from Dan Gelbart.

Yeah, I was struck by that too. It was very interesting and informative to me as well; I hadn’t known about the higher accuracy constraints for mirrors or the reason why. Also, even though I knew about using positive and negative lens elements to cancel out chromatic aberration, I didn’t really understand how you could do it without losing optical power.

We need moar Dan Gelbart! UBC, please, begging you, if you have ANY more material from DG, please post it on YT :) Pretty please! (I have watched all of the 18-part tutorial on Prof. Gelbart's own channel, and all of the other videos too, several times over. Just can't get enough! )

The guy that came with the idea of the electromagnet that attracts copper is/was Leonard R. Crow. He published an small blue book titled "Design, Construction & Operating Principles of Electromagnets for Attracting Copper, Aluminum & Other Non-Ferrous Metals" in 1951. Not mentioned in Gelbart's presentation is the fact that the piece of copper or aluminum to be attracted has to have a certain shape. Too small, too big, too long, etc. and it won't work.

It was all fascinating, but the most important part of his talk (IMO) is in the "Knowledge" and "Invention" sections.

The electromagnet - is this an exmple of a shaded pole. The current in the shaded area will lag
@DEtchells
Жыл бұрын
Yeah, that was especially interesting. Tricky to get the balance right between the shaded pole and the main ones. I’d also expect it to run pretty hot when in use, but I guess the super-heavy copper on the shading winding helps minimize the losses.

@@DEtchells dear Dave that's why he's Dan gilbart. Quite an original layout. Somehow we always assumed that shaded pole is tied to a rotor. But original thinking takes one out of the box. Absolutely fantastic 🙏🙏 and on the lighter note i should be exempt from any exam in all of Dan's institutions😁😁😁😁😁.. thanks for your reply please

I was picking up toys with my kids a few months ago, and they asked if I could make a magnet that could pick up plastic Legos... I said no, then kept thinking about it until I came up with a solution. I was very excited and told them how inspirational they were. For what it's worth, the (unbuilt) solution I came up with doesn't involve using magnets at all, but instead would just fake it using machine vision and quick little sticky grabbers or something.

The answer to avoid the test could be, that we are dealing with an electro magnetic field not just magnetic field, the electromagnetic field has 2 modalities as its name says (magnetic and dielectric), all materials interact with these fields some more with the magnetic and some more with the dielectric when directly exposed to them. In this case the osilating magnetic field is generating a current in the cooper ring, that can't flow so I will expect this ring to heat up but as soon as you bring closer the cooper plate this current generates a week magnetic field in the cooper which is attracted by the magnet, if instead of a cooper plate we bring a unifiliar coil connected to a small light led it should turn on by inductance.
