Love it, and im gonna steal this. One of my favorite past times is getting into arguments with friends who are anti science then doing simple experiments like this and asking them to explain it.
Mirrors don't reverse up and down. Only left and right. Just a little something to keep you up at night. No replying with answers why, folks! We must allow the thoughts to invade.
You ever look at a woman's face and think, dear lord I need to spend more time taking care of my face. I'm like a lathered handbag that was left in the son and who also doesn't shave enough or pluck where he should. Damn it. Why am I so ugly ?!?
when light goes thru the glass, it goes thru two piece (front and back). each time the image flip, so it's the correct position. After she pour the water in, the glass and water became one huge piece. This biconvex lens flip the image once.
I remember seeing an extra credit question is a physics book. They had a picture of a prism and a large font words IRON OXIDE on the page. The next picture was the prism over the words. They said the prism contains iron oxide, but asked how that made it so that only the letters R and N had been flipped over. I missed an entire class staring at that, trying to figure it out.
Mirrors are different from lenses in the sense that they reflect the Z axis which is why they look different left to right but not top to bottom. Lenses work totally difference, especially if the material changes halfway through and you have to calculate refractive indexes. Either way, you'll only see x and y axis shifts of light paths, not a z axis extrusion of reality that you see in mirrors. So really mirrors are basic and lenses should blow your mind.
Eh. I'm getting to be a bit hard of hearing in my old age; I need people to speak up more. She's about the right volume (compared to ambient sound in the video) for me. Wish more people would speak louder TBH.
Sometimes I fantasize about being in a time travel story, and trying to explain Germ Theory to historical figures. I imagine that understanding lenses is the first step - how do we know there are things too small to see? Well, we make them visible with tricks
That's the point of the lenses. A rookie time traveller, who hasn't been obsessively planning for this event, will start yelling about germs and lightning and smartphones. I'm just gonna say "Oh, you want to know the secrets of the universe? Let's look at some pond water, this is gonna be fun."
What's really going to get you, is that your vision is passing through your more-or-less spherical eyeballs, that are filled with a gooey fluid with a refractive index of 1.3. Also you are viewing the world upside down.
One time I had a seizure in the middle of the night and when I woke up my vision was upside down. It was really hard to get to the bathroom because I had to do some serious mental labor to put my feet in the right places. Eventually I gave up and did it with my eyes closed by memory. Lasted about two hours.
Not so minuscule though as to not be able to trick the brain into ways of seeing the lag. The best is usually something like the second hand on a clock and looking at it in between movement to where it has to be paused an extra moment before syncing back up. That explanation is garbage but ah well
Yea, eyes are amazing, my eyes got a bit fucked for a few weeks but eventually my brain learned to compensate one eye dilating oddly. I can mostly see fine but when my eyes get tired i start to see double vision again.
Dont have much money or insurance. From the internet, i seem to have messed up my pupils. I have the bad habit of using my phone at night with one eye less focused or closed. When it happened i was very depressed and had taken melatonin to fall asleep. Don’t actually know if either factored in much.
The bit ive never understood is WHY does our brain flip the visual information from the eyes? Is it more efficient to map it to other brain areas? Why would we not simply learn from / act on the info as its normally available?
But why does that involve rotating it, is my question. I understand there are lots of other cool hacks involved to fake or assume detail, presuppose location and colour, make threats larger etc. But why the flip
A smaller opening to admit light improves the sharpness. The lens on the outside of your eye focuses the light through your pupil, then the focal length of that lens causes the light that passed through a tiny opening to hit a larger area on the back of the eyeball, where all the rods and cones are hanging out, so they can tell your brain where the light is coming from and how much red/blue/green there is.
Sure. But, again, my question is: why does your brain flip the resulting image? Its not a mechanical consequence of how light travels through the eye - our brain has evolved to flip the "image" we see. Why? Why not just use the image it gets?
Yeah, they did that experiment where you get glasses that 'rectify' that so you see everything upside down, the brain compensates for it after a while and you see normally again
And then!! Once you're used to it and the brain adapts, the world is upside down when you take the glasses off for a while. Our brains are stupid and I'm fascinated by them.
Adjusting back is faster, but saw a video with 'prism lenses' goggles, playing tennis, took a long time to be able to even hit a ball, but after an hour or two, they came off again and it took several minutes to get back to normal.

I’m blind.. thanks.. can anyone tell me wtf this bitch is saying? I have a brail translator so no worries…

so everything we saw is the opposite?

It’s more about the shape of the glass lol

More science videos? More like science clips. Videos are lengthier.

That is not correct at all. Maybe check things before you go commenting so confidently.

If you enjoy this mirrors are going to blow your mind

If you do the water arrow thing in front of the mirror, no change! Take that science!!

If you look at a mirror, you may be shocked to find that the image you see is actually reversed!

But only in the horizontal.

Does your fantasy ever end with you getting burned at the stake?

Most of the time. I curse the villagers just before they burn me and about a week later they all die from the flu, because germs.

That's the point of the lenses. A rookie time traveller, who hasn't been obsessively planning for this event, will start yelling about germs and lightning and smartphones. I'm just gonna say "Oh, you want to know the secrets of the universe? Let's look at some pond water, this is gonna be fun."

Ok, I get it, but take some modern weaponry just in case....."This is my BOOM stick!"

Lol just in case, take a gun if you can, then act like you're a god with a magical thunder arrow. They'll listen to you then.

I remember it blew my mind when I found out we don't actually see in real time. Granted, the lag is miniscule by any measure, but still.

Oh yeah? Then why aren't I falling onto the ceiling?! Hmmm???

That's the floor. You're walking on the ceiling
SimplyWalkedIntoMordorAndBroughtPizza
so australiens do actually see things right?

Sadly their world *is* upside down, so they suffer the same fate as us. They also suffer swooping season.

FortKnoxbutforBagels
It's more about the optics to get a decent image. Eyeballs basically have to be pinhole cameras otherwise your vision would be super blurry.

But why does that involve rotating it, is my question. I understand there are lots of other cool hacks involved to fake or assume detail, presuppose location and colour, make threats larger etc. But why the flip

Whaaaaat I want a pair!

Even better, after a prolonged period wearing glasses like, you have to adjust Again when you take them off.

This sounds like an amazing way to spend a Saturday, honestly. Esp at the beach. That would be trippy as fuck.
