In 1952, when this video was first made, scientists hadn't observed this effect in action yet. This was all theoretical until 1956. And it worked just as this video explains it, 4 years before the actual observation Science is amazing.
I think this is one of the movies mentioned in the Feynman lecture series. Dated but still fundamental, clear and accurate at least on the two dimensional hexagon pattern.
Indeed, with pure gold, no surface passivation exists, so dislocations can move all the way to the surface, as shown in this video. My thesis is that a thin film of pure gold will not get stronger with reduced thickness while a film with a surface passivation (eg titanium) will strengthen with reduced thickness.
I love BUBBLES!!! I know I'm suppose to be wrong... BUT EVERYTHING IS JUST A BUBBLE!!! Big bubbles layering over smaller bubbles... those smaller bubbles are made of smaller bubbles.... over and over and over again.... is a bubble a sphere?? YES... but what happens when it cools or freezes?? How much pressure and surface tension would be needed for a bubble to change shape?? ALOT!!! Like Big Bang level stuff... maybe something the size of our sun could do it??? Not to mention sound waves are just bubbles too!!! Light isn't a bubble... photons aren't what they think. Philipp Lenard was right and wrong... light doesn't travel like a wave!!! All matter does!!! Energy??? Is that bound by inertia?? NOPE! But does the wave wobble or does the wobble wave?? Ring bubbles, sphere bubbles, wobbly bubbles, twisting bubbles, wavey bubbles.... bubbles bubbles bubbles!!!

Science is amazing.
All respect for the wonderful and brilliant experimental presentation. Unfortunately, not many people appreciate the science of physics
Why haven't I seen this video before?, such a fantastic explanation!!!

This is pure gold. Thank you so much.

Just read about this in JD Watson's book The Double Helix, did a quick search et voila! Pretty cool.
Outstanding demonstration using old technique of bubble rafts.
Thank you! 😍
Fantastic explanation! Awesome!!!
very helpful to understand movement on the earth crustal deformation
Here from the Feynman lectures!
Such an awesome video....our modern 3D animations are not good at creating this impact of reality...
Very beautifully explained. Thank you so much for this.
Wow! I am impressed! Great video!
Awesome content, thank you very much!
Had to write a paper on this, used this as my source.
changed my life
Good!
¡Qué belleza!
优雅而科学
