Why you'll never see a right angle on a stealth aircraft - corner cube reflectors

My collaboration with Geoff is here:
• Cube Reflectors on the Underground
Retroreflectors send light back in the direction it came from. They are useful in lots of way. But accidental retro reflectors need to be avoided sometimes.

Normal Scientist: Meticulously proves the geometry of the phenomenon. Steve: "Just look at it"

Smooth... I like how smoothly you feed science... I'M YOUR NUMBER ONE FAN!
-
lure me in with fancy stealth topics and talk about cube corners the whole time. cheeky...

Steve: “Is the moon sneaking up on us?” Moon: slowly backs up at 4cm per year

Steve: Is the moon sneaking up on us? Moon: backs away slowly

Ah, "Proof By Look There You Go It's Doing It" is definitely one of my favourites. The only thing that can beat it is "Proof By Pouring Things Out Of Beakers".

This was really informative Steve! Just by chance, I've been playing around with the anti-paparazzi fabric to use in my puppetry. Cool way of making the puppet really visible while I remain in the shadows :D
-
"A proof by 'Look! There ya go!'" That is the best quote I've heard from you yet Steve :D

I can actually remember when I first noticed the 90-degree mirror effect. When I was a young child, I was in an ice cream shop, and they had a corner mirror by our table. I ended up shuffling from side to side, fascinated that I couldn't stop the corner going right down the middle of my reflected face. I worked out what was happening in the end, but it took me a while :)

I’m a land surveyor, we use reflectors like this for most of our work in order to take measurements within 1/1000th of a foot/sub millimeter accuracy over very long distances. You can look into the prism and the pupil of your dominant eye will always be at the center of it.

As my geometry teacher would always say, "What if it's not drawn to scale?"
-
Fun Fact. In classic Doctor Who they sometimes used reflection to do alien glow effects without needing any post production. One of the best examples of them doing this is in the Silvester McCoy episode Silver Nemesis. Some shiny fabric and a guy with a bright light behind the camera is really cheap ;) PS: I love it when all my favourite content creators collaborate unexpectedly :)

"90 degrees or 1/4 tau radians" perfection
-
A proof by "Look, there you go... it's doing it" Best proof ever
-
1/4 Tau Radians I'm surprised Matt Parker didn't appear just to frown at Steve in disappointment. Go Steve!
-
Perfect companion video to Destin’s Smarter Every Day video on the topic! You all should have a collaboration
-
Title: whh you dont see eny right angles on a stealth bomber. Video: BIKE REFLECTORS!
-
This is actually a rather curious topic that I haven't often thought about. Also, appreciate that you show directly what you're talking about when explaining it lol

lololol Creeping moon. I love this channel. I had just barely found it a few days ago and subbed immediately.
