Quantum Tunneling At Home

I show you a great analog of quantum tunneling that you can do at home

I’m adding “quantum tunneling” to the skills section of my resume

Remember this is just an *analogue* for quantum tunneling, not a demonstration.

His finger touches water on the edge of the glass which has an in-between index of refraction between the air and glass which no longer causes the total internal reflection (and the light goes through)

Video games have this issue. Basically the computer checks the object in one frame and the speed of it. If it calculates that where it should be in the next frame is free of obstruction, that object can pass through barriers.

To fix this, we can do a few things like increase the ticks/ frames per second but that increases processing requirements so just making the barrier thicker is usually a good solution. But there's other methods that can cause unexpected results.

Please make a longer video explaining this in detail.

Bro I accidently slept watching this short on 4am and it's ran till 7:30am

imagine being in a fight and someone’s arm just goes straight through your gut like a mortal combat fatality

One of my favorite things about physics, that the possibility of something or someone hitting something so hard they just pass right through is not zero

"mom, can we have quantum tunneling?"
"no, we have quantum tunneling at home"

What is shown in the video has nothing to do with quantum tunneling. We see the total internal reflection between the glass and the air: we remove the air - the reflection disappears.

“Yes”

-Phasing- Quantum Tunnelling is one of the best examples of “if you think you understand Quantum Physics, you don’t”

Boundaries are 1) Finger to air, 2) air to glass, 3) glass to water, 4) water to air. Each boundary both reflects and transmits photons. The transmitted photons are refracted. That means the transitted photons change direction by the refraction angle at each boundary. Pressing your finger on the glass replaces two boudaries with one boudary (finger to glass). This results in a change in refraction angle which allows you to see the finger from a different angle than before. So in ALL cases there are always photons "tunneling" thru the various materials. This means your analog is not a good one because all materials (air, water, glass) always have photons tunneling thru them. You demonstrated this in the video by changing the glass angle with respect to the camera so that the photons were directed either towards or away from the camera.

“Can I have glass of water?”

“You mean quantum tunnel?”

Maybe this wins the award for the coolest-sounding mundane thing ever.
