holo eclipse with diffraction grating! 🌈🌙☀️💥✨

I decided to sacrifice an old camera for the eclipse and see and capture everything through the camera screen. I guess the clouds in Monterrey acted as a filter, preventing my sensor from burning out 🙈 lol

Even if a planet is lucky enough to have a stable orbit that weaves between the spikes, the seasons get weird whenever it passes close to them.

Clinton Joseph Davisson (22 October 1881 – 1 February 1958) and Lester Halbert Germer (10 October 1896 – 3 October 1971)

Both American physicists, Lester Halbert Germer was a junior assistant under Clinton Joseph Davisson when the two of them performed an experiment that led to discovering electron diffraction. Davisson would be awarded the Nobel Prize in physics in 1937 for this discovery, shared with George Paget Thomson, who discovered the same thing independently. Germer, as an assistant, did not share in the Nobel Prize, but his name remains attached to the experiment itself. The Davisson–Germer experiment was conducted on a nickel surface; bombarding it with electrons with known momentum at an angle, a diffraction pattern emerged. It was the first demonstration of the wavelike nature of the electron predicted by de Broglie.

Diffraction art by elkement, 2024

Inverted Atoll

Applying my 'quadrant scheme' to inverted diffraction art!

Four different viewing angles - looking at the same virtual 3D structure built from diffraction curves!

Created with javascript, based on threejs, no AI.

In the center of the structure is a hypothetical diffraction grating with 4 slits, 330 nanometers wide, 4500 nanometers apart - sort of reasonable parameters from the perspective of physics. Beams of white light hit the slits, light is diffracted into pure spectral colors. 200 lines, walking through the spectrum of colors in 200 steps.

This was the physics part, now the art part :-)

- I am inverting the pure spectral colors. Probably an alien from a foreign galaxy would see the colors like this. - I do not simulate the diffraction patterns as you would see them - just blurry stripes of colors. But I take the mathematical curves that describe these stripes. What fascinates me is that optics and diffraction is one of the few fields in physics where vibrant colors also make sense and are "correct" and not only an arbitrary choice for visualization. Showing a peak where the center of a stripe would be in an experiments makes the artistic representation similar to the natural phenomenon but not exactly the same. - I look at the structure from different angles and at different distances. Like a space probe exploring a weird, colorful anomaly in space :-) - I like the Moire effects and irregularities, maybe even potential "rendering errors" when overlapping the lines. - It is an "atoll" - I completed the circle, so white light would hit the grating from two directions, 180° apart.

something that always helps me whenever i am feeling unmotivated or resentful towards my studies (mostly because of the toxicity surrounding the competitive nature of the exams i am preparing for) is pausing for a sec and wondering how exactly the particular concept came to be in front of me. how many nights did the Curies spend awake discussing the whys and hows of radioactivity? how exactly did Henry and Raoult think of solvents exerting pressure differently in different cases? did Franklin have to worry about fighting patriarchy besides working on her discovery? did Stefan/Boltzmann ever know we'd be able to calculate the temperature of the Sun? did they know their passion and their love for their respective subjects would be influencing millions of lives down the road? did they? and so i take another breath, mutter a thank you w my head up and continue.

sometimes you run into something that just overturns your understanding and builds a new, more coherent picture. this is one of them.

they taught us about diffraction theory at uni - Fresnel, Fraunhofer all of that, we did experiments with lasers - but it never occurred to me to analyse lenses in terms of diffraction. it makes so much sense now! i was never entirely satisfied by the ray approximation to light, so seeing what's really going on in the lightfield and how you can use a diffraction plate as a lens, with each ring contributing higher order Fourier terms to the image, is like. crazy cool.
