A 1/4" hole drilled in the wall and a fiber optic camera w/ LED should reveal all, no?

No need to change anything on my account, but I think a title like "Simple Optical Illusions to Entertain Children" would be much clearer.

Maybe that's just me.

I also need logarithms daily as an optical engineer.

That said, a CPU only does +,-,*,/, and approximates everything with those basic functions, so maybe he's onto something...nah...:)

That shot at 3:43 created an optical illusion for me causing me think the depth was inverted (the way those inverse/hollow reliefs appear to continuously follow your point of view; I'll link if you don't know what I'm talking about).
Anyway, if you can get your eyes to do, quite trippy. It made the river look as though it were perfectly balanced on a long ridge, with the forest falling away down sharp cliffs on either side. I think my eyes were focused on the river at the time.

That was about half way through.

I wanted to see the part where the optical recognition system detects fragile stickers and gives it an extra big boot with a robot foot.

I agree, incredible. Not only incredible how scientifically brilliant we humans can be, but how incredibly wasteful we can be. I mean, Jeez, this piece of optical wizardry was simply dumped in the trash!!!

With 83x optical zoom it is a beast in deed!

someone should introduce these guys to fibre-optics...

Also, I don't see them wearing any ear protection at all - those guys who live on site will be deaf by the time they're 30. (if the company lasts that long)

Does the electricity provider accept Bitcoin as payment?

Hopefully nobody tells the Chinese government that Bitcoins are often used for illegal activities...

After years of watching hundreds of optical illusions, magic tricks etc , I really thought I was immune to the best possible versions of this kind of stuff, but this one caught me out completely. Absolutely brilliantly done.

I didn't catch it until she lifted her legs. And even worse, its SO obvious once you see it. makes the trick better IMO

? I'm confused. I admitted my 'test' was lacking, and deferred to @ChaosEngine who didn't trust his eyes but measured...so I am no longer certain it's 'fake' at all, in fact I was careful to NEVER call it 'fake'. Perhaps you only read my first post in this thread and missed my admission that I was wrong?

As I said, I think there's a reason it LOOKED like it did to me...probably the surrounding color reflecting off the white paper I used to mask off and 'coloring' the grey squares....and likely the paper I used was not perfectly straight to use as a straight edge....and measuring anything on a screen is less than perfect, which is why I poorly measured the table and lines...the second time I measured it I did better, and I admit they are the same size contrary to my original statement.
I also only saw grey pills.

The reason I was skeptical is I've seen these same 'illusions' faked many times. For instance, the last time I saw the Rubik's cube, the tiles had dark shaded colored edges they removed when 'masking off' which obviously changed the color. It's not that I don't 'believe' in optical illusions, I just think people are cheaters more often than not these days and fudge things they don't need to fudge. This time it was my method of 'masking off' that seems to be my issue...I don't have an image editor that will do much for me here....sadly...but it doesn't mean I don't trust Chaosengine who did and set me straight.
OK? ;-)

Your video, Virtual reality, explained with some trippy optical illusion, has made it into the Top 15 New Videos listing. Congratulations on your achievement. For your contribution you have been awarded 1 Power Point.

It is bullshit, but it's not a problem unique to Apple.

I've never owned a mac, but every goddamned Dell laptop I've used has had a subtly different charger, and they're mostly just a round plug!

As for usb-c for video, meh. People kvetched when they dropped the optical drive, the VGA port, etc. (Hell I remember people complaining on the windows side when laptops stopped having serial ports!) Technology moves forward... and Apple is known for pushing new techs at the expense of old ones.

Still can't believe they put a 480p camera on it, though.
Seriously, what is this? 2005?

Lol. Right. I was curious and tried to Google the price of one and didn't have much success... admittedly I spent like less than 2 minutes before giving up (aka I scanned the first page and first page of shopping), but near as I can see, a good optical microscope will cost $2-4k, with most high end hobby ones around $3-500 range. I doubt there's a hobby range in SEMs. The only one I saw during that minute and a half search was a used one for $25k another for $27k and an auction listing that went for $2k (which compared to others seems out of price). Anyhow, between the auction price and the used listings, I figure roughly you are looking at $5-25k if you know where to look... Who knows what actually spending more time would have given me, but either way, I'm fairly sure a SEM is beyond most people's budgets.

Actually, since the development of adaptive optics, ground based telescopes aren't obsolete at all. Even without adaptive optics they have their uses, and some interesting science is done with them.

Getting telescope time on a space based telescope (or large ground based telescope for that matter) is quite hard, which limits the things astronomers can do with them.
