This is by far the best demonstration of Moire interference I've ever seen. Talking from an eight years of photolithography process engineering experience.

playing a natural harmonic on a guitar at the 12th fret on the low E string matches the hum of that projector exactly

Loved this show. He helped me understand as a kid that when I was flying to the Philippines from the US, why you went up by way of Alaska instead of going straight across. He used string and a globe. It was actually shorter to go that way.

The best example of moire patterns I've seen on You Tube!

Great video!!

Perfect one exact to idea thanks Mr. Wizard

I remember Mr. Wizard was on TV. In one episode he meaured the size of a molecule

"Okayh!"

Wholesome!

Still didn't help me understand why the water silk makes waves... you need 2 overlaping patterns or look at a pattern at an extreme angle, don't you?

It might be because silk is woven. Which consist of threads going up and down. Which might be able to create two over laying screens of spacing proptional to the holes in the silk fabric

Ha they're so sweet together. Love how he isn't patronising at all, he's really actively involving her and they're co creating together, she feels free to think aloud what she's seeing and thinking. Wish more teachers were like this.

What ever were these guys doing that made her out of breath.

Sir, What is the practical application of the moire patterns?

In physics, Moire patterns are used to determine interference wavelengths, especially with soundwaves.

Narendran D it gives the camera people something to screech about :) Its gotten better over the last 45 years. I was watching "All in the Family," every time someone walked across the set, any vertical lines at all looked wavy...it's not as bad today, even on consumer cameras.

Mainly used in interferometry, since light waves can behave similarly

I love you Mr. Dress Up. God bless you in Heaven Sir Gravity is the 4-Dimensional Shadow of Time-Space: I suspect the answer will be revealed to be the perfect ratio of 3's & 7's- like The Negative Mystics of the Mechanistic Sublime: Walter Benjamin and Lovecraft's Cosmicism. If you want to get more detailed you could say Gravity is the 4-Dimensional Electromagnetic 'Moire Pattern' of Time-Space.
