This is oddly satisfying to watch.

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

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 1d 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.

Optical engineer here. Yes, indeed

All of this just to get to a Pink Floyd album

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

There's a lens for that

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

Feels like lens effects is mostly same.

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

Lol walked right into it. Should've known

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

u/smokysadness 21h ago

The sound effects hurts my ears and brain...does anyone else feel the same or is it just me?

This is very incorrect AI slop

u/cajunjoel 1d ago

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

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

u/Yeet-Retreat1 1d ago

Its a simulation of actual physical mechanisms.

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

u/Mammoth_Spend_5590 1d 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 1d ago

IQ levels have significantly dropped in such a short time.

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

1

u/Mammoth_Spend_5590 1d 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 1d 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

1

u/Mammoth_Spend_5590 1d 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?
