This is oddly satisfying to watch.

It just keeps going!

Hung in there until it got peak Pink Floyd

Everything under the sun is in view, but the sun is eclipsed by the moon

•

u/fern-grower 9h ago

See you on the dark side of the moon.

Whats the point of the "Planos" when they behave the same as their non plano lenses?

•

u/physwolf2759 11h ago

Optical bro here. Plano-lenses are a more optimal shape for simple focusing / collimating as compared with even bi-convex / bi-concave lenses. The most optimal shape here for a singlet using spherical surfaces is known as a "best-form" lens, which is quite close to the plano variants, but the plano are often good enough and cheaper to produce.

As someone who worked in optics… yes.

•

u/Dunderman35 8h ago

Optical engineer here. Yes, indeed

•

u/DHaas16 8h ago

Random dude here. Heck yes

All of this just to get to a Pink Floyd album

u/Still_Barnacle1171 11h ago

would be nice if the writing that told you all the names was in focus

There's a lens for that

I downloaded the video to my phone and it was much sharper

Now memorize those for your pop quiz tomorrow

A brilliant and simplified visual explanation of how light behaves and interacts with various optical components with incredible precision

•

u/Kastoook 11h ago

Feels like lens effects is mostly same.

•

u/Constant_Air9693 10h ago

I feel enlightened

•

u/Eagle_1_4 10h ago

When would you need a perfect round lense to reflect light?

•

u/ignatious__reilly 10h ago

I really enjoyed this

•

u/veganxombie 10h ago

how do I get this screen saver

•

u/Electrical_Name_5434 7h ago

Wish I saw this when I first introduced to optics…feel like it would have made everything easier to visualize

•

This is very incorrect AI slop

•

u/Mammoth_Spend_5590 11h ago

I wish this was scientifically accurate physics and not hallucinated AI slop

•

u/Yeet-Retreat1 10h ago

Its a simulation of actual physical mechanisms.

Such a dumb mf sometimes I can't take this boomer shit

•

u/Mammoth_Spend_5590 10h ago

Yeah pretty much.. I remember when physics engines didn't just make the maths up and spew out what it thought was right. It's scary that since the release of mainstream AI, IQ levels have significantly dropped in such a short time. And will most likely continue to do so.

•

u/StoneyBolonied 8h ago

IQ levels have significantly dropped in such a short time.

Would you happen to have any evidence to back up your claim?

•

u/Mammoth_Spend_5590 8h ago

Yes look up the reverse flynn effect. There has been a steady decrease in IQ levels since 1970/1975. Researchers point to environmental and lifestyle shifts (rather than genetic) such as changes in the quality of education, less reading, more screen time, and altered media habits.

•

u/StoneyBolonied 8h ago

But mainstream AI wasn't released close to 1970/1975?

Not to mention the only thing an IQ score actually gauges is a person's aptitude when it comes to IQ tests.. I believe using it as an objective measure of intelligence is misguided

•

u/Mammoth_Spend_5590 8h ago

The drop in IQ levels has had a sharp dip since the release of mainstream AI. It's also a worldwide study that's been independently tested by multiple other countries. Did you look at the case studies?

•

u/cajunjoel 8h ago

This is cool, but I wouldn't mind a higher quality video. Those words are hard to read on mobile.
