Why does my light has these moving lines I can even see w my eyes

The bulb is pretty old and it's not as bright as it used to be but it's still OK (I cranked down the ISO for better visibility)

5D Schrödinger Surfaces

5D? Really? Yes. 3 spatial dimensions, 1 temporal, and 1+ rotation. This is an abstract way of visualizing the nested dimensions in String Theory.

Scalar Field

The scalar field of sin(2π(xy+σ)) oscillating as σ increases.

Red represents positive values, purple represents negative values, and sky blue represents values close to zero.

Anybody ever seen double slit captured, not modeled, in 3D?

I've seen loads of 3D renders of how the double slit experiment works, but has anybody ever tried capturing the wave in 3D?

I picture a normal double slit set up but with a projection screen that moves in the z axis, closer and farther from the slits. Use a locked off camera or two to capture the result in hundreds/thousands of slices, that get assembled in the computer, removing the background in each slice and only showing the light, so you can reconstruct the wave pattern in 3D of actual light.

Would they be straight beams of light, or would they curve around like wave ripples, peaking and dimming in curves?

3D models are cool and all, but I want to see the actual light waves suspended in the air.

Easy tool/Software for making engineering/physics animation?

I am a mechanical engineer and running a youtube channel. I plan to make videos/animations related to engineering, physics and technology. I am looking for a best and easy to use tool for making animations. Can you guys suggest tools for making animations.

I captured a slow motion video of a thrown tomahawk hitting the block and rotating in a very strange way.

I thought this was so cool, I've never seen anything like this before.
