The narration on this is a bit flat.

You are the WORST speaker ever. Your inflection, enunciation, pronunciation, pregnant-pauses followed by a vomitus finish to a sentence is not tolerable. I'm beyond out. Lookup blue or red nile. He's actually worse. And equally not tolerable. You might learn a little about how not to terrorize people's ears by listening to him. As he was ALSO raised by a pack of deaf goats.

Is this a bot speaking? Horrible. It burns the ears.

"Sil-cone". Um, no.

I do a lot of scale modelling and have to make many bits of plastic and wood that perfectly match another piece. It's a real nail-biting experience when trying to make something "flat" and line up perfectly with another surface. It gets even worse when I'm trying to make something a consistent thickness while making one side flat. Every time I take a measurement I know that errors are being compounded and the resulting finished piece will show the combined errors and affect other parts. For some reason, I find this fun. Great video!

Related to this subject, what I don't get is why do suspensions have arms? What purpose do they serve? Even with adjustability it would be more compact to just mount springs/uprights/whatever to the side.

Wow.

I expected all comments on this video to be Rick & Morty memes.

It takes a circular object to make a flat surface

Now is a bowling alley lane flat or curved to the curvature of The Earth?

Sad to see all this knowledge, these permanent improvements for each tiny critical part of an engine will be soon useless.

My ex GF was the prototype for creating flatness.

I feel like wringing may have something to do with the fact that even air cannot get between the two surfaces to push it apart. Or it is electrical somehow.

Excellent, good job and thank you.

Wow this video was m

And no, it is known why flat surfaces attract each other you just didn't research it. Like common, it's a bit silly claim to say it's unknown in the day of age where we know about subatomic particles and pursuing to find the theory of everything... Don't mislead ppl please

Checking for flatness - or another idea - if someone isn't an idiot, they could use surface plate, check multiple points along the surface, and then calculate flatness by using MATH to subtract imperfections to parallelism from minimum and maximum deviations of result.. Cause such math is almost primary school grade after all....

Okay so flat can be achieved by creating a controlled surface out of two imperfect ones; great. But then the video started to get into the thickness of an atom. Here's my complaint: If you even breathe on the surfaces of a plane so flat at the atom scale you will warp it with your bad onion or garlic breath.

This aged like fine warm milk. Elon is launching massive deployments ot Starlink satellites into LEO with cells setup so when the constellation is setup completely all boundary cells on the terrestrial surface will be lit. The mobile service is just moving you from cell to cell, and it costs more.

What is flatness? Mountains and valleys. After tribology I learned flatness is 100% an illusion and surface finish is as easy to represent as coast line length. Depends on how much you zoom and how much you want to simplify for generalistic average that doesn't represent the surface. But rest easy, apply very thin lubricant coating for elastohydrodynamic lubrication and you're cool. In manufacturing on the other hand I also learned geometric tolerances are one of the biggest problem sources on drawings when working with subcontractors or even your own staff. Don't use them and all your measures can be freely interpreted to describe any real life shapes apart from your ideal or functioal idea of the part dimensions and shapes.

How flat is the earth though?

*Sigh* I should call her.

The definition of flatness quickly become what? @ 15:31 ?

Flat = superior!

Koseki Bijou could understand this easily, she can relate to this science

No pianos were harmed in the making of this video

Beautiful engineering! Thank you!

Impressive video. This is why KZbin needs to exist.

The concept of "wringing" is particularly interesting to me -- the idea that surfaces flat enough can spontaneously bond by rubbing them together.

I'm familiar with the bubble, Morty. I also dabble in precision. And if you think you can even approach it with your sad naked caveman eyeball and a bubble of air, you're the reason this species is a failure, and it makes me angry. -Rick Sanchez

My wallet is the flattest thing I know 😢

You cannot reason with women. They operate on emotions & feelings, rather than logic & reasoning.

This video felt really flat

So flatness is about the surface not the shape? In order for a surface to be flat it need not be planar? Is there a property of smoothness that is distinct from flatness?

Tables are flat, the abuse of science to redefine what flat means is what you are talking about.

Interesting factoid. Modern glass is made to such high precision that it can be used as a poor-mans surface plate. Basically if you need a reference surface for precise sanding or testing flatness of a project, an offcut of thick glass can work perfectly. For those of you who dont know, a surface plate is usually a big granite block that is precision ground flat. You can do things like tape sandpaper onto it and then sand a metal part so its face is perfectly flat. They are quite expensive compared to a bit of glass though.

Flat earthers probably got so excited clicking on this video 😂

:O ... I understand now why Morty freaked out so much.

Who was that dude that said air isn't a fluid

15:30 quickly becomes ... ? What?

I love meticulousness.

take a shot for every time he says flat

Only Rick Sanchez can produce true flatness.

Thanks for mentioning glass lenses!

Way to open the video with gaslighting 😂 “flat” in the normal world refers to objects on the macro level, not the micro level that you’re diving into in this video.

It’s true level

This is a cute video. I maintain planarization tools for smoothing silicon wafers in microchip manufacturing.
