I am 62 and thought I understood many things, just through life experience. But then Mr. Science shows me the shadow of a sphere is the letter J. Instantly, I become completely still, no movement. Even my heart ceases to beat as I gaze at the screen, my mouth agape. Mind blown! Epilogue: No worries. I came back to my senses in due time, then finished eating my sandwich.

We had Ray optics and wave optics in school, in 11-12th grade. A bad teacher and my restless 16 year old brain meant that I hated the subject as looong as I studied it. Should've put some effort myself too..... Damn

during a solar eclipse the shadows of leaves will each have a little crescent cut out.. seeing thousands of little mutated leaf shadows under a tree during an eclipse in 1984 blew my young mind..

Oh. my. god!!! I can absolutely see how ancient humans thought that it was the curse of some dark god from beyond the void, or your choice of creepy mythological or spiritual event of great significance. Not only does it threaten your source of light and life in the sky, the balance of the heavens completely disturbed, but it also does strange things to the laws of the world around you. I experience the (partial from my location) solar eclipse over the USA a few years ago, and I'm not sure if it was complete enough to show a difference in the image compared to normal shadows or not, but now that I know, next time, when I'll be in totality, I'll make sure to watch out for shadows changing shape, *and* the finger circle camera thing he did, I didn't know you could see the eclipse like that, it would have been so cool to try! I've seen people build pinhole cameras like that using a DIY guide or a kit, just for the eclipse, but even tho I knew how they work, I thought it needed to be much more precise than that!

@Koro Sensei thank you very much, that actually cleared it up quite a bit, it's so weird to think about but I wonder what it is about the actual "small hole" that makes the light go through it as a cone instead of just a piece of the light beam

Vor 3 Monate

Koro Sensei

@Beast If you shine a light trough a box, which has, for example, a cutout of a star on one end, and a small hole on the other end, the light coming out of that box, trough the small hole, will have the shape of a star. He gave the example of eclipse, as it does the same thing. When you make a hole with your fingers, the light that comes trough that hole will have the shape of an eclipse. No, light doesnt cut off, thats what makes this fascinating. The play with the shadow shape is even more mind blowing.

Vor 3 Monate

I legit watched this intently over and over and I don't understand either. "When you shine a light that has a shape through a small hole" so wouldn't most of the light beam get cut off?? Does he just mean the stencil is very small? The thing about the eclipse is completely confusing to me. Seems irrelevant. The shaped shadow comes from him using a flashlight with the shape he wants to shadow, over the lense,I think.

This is really interesting! I love all types of science. Really wish I would’ve had more time to take more science courses in college!😕 But I was completing a duel major & minor in psychology, nursing & history. So I *made sure* any non-history electives I took were extremely easy…both for my sanity & GPA! I took 4 semesters of classical guitar, a few art classes, yoga for a few semesters, etc as I had to take an elective every semester for 9 semesters. As I took classes Spring, Summer, Fall & Winter in order to finish as rapidly as possible. So I honestly NEEDED such easier classes for my sanity!! But I wish I could’ve/would’ve taken advanced sciences instead.

Now that street lights are using LEDs, when its light goes through the tree leaves onto the sidewalk, you can see the shape of the lights in hundreds of places. 🌞 Once seen, you can kind of see the Sun (or moon) do this also in hundreds of places without an eclipse, as circles.

Hey action lab, what do you think it would be like if you had one eye in the front of your head and one eye in the back? Clearly youd see both positions at the same time but do you think there would be a clear separation of vision like a line in the middle or side of your vision? Do you think if you did this to your eyes right now your brain could handle this kind of sensory overload?

It's inedible how some basic things can be extremely counterintuitive to us because it's not directly related to our success as a species. But like, of course that shadow thing is going to happen, light propagates in a straight line. Yet it's kinda uncanny.

@SomeDudeThatWatches Try picturing an extended light source, like the star or J, with the ball in front of it. If you move your head around behind it, the ball will only block the light if it’s between you and the light. It’s just like how nearby objects appear to move past distant objects as you drive by.
