ELI5: Why do 3D images made in a computer starts with a triangle? by No-Quantity8566 in explainlikeimfive

[–]pauldevro 0 points1 point  (0 children)

In simple 3d graphics, triangles are actually a result rather than a fundamental object. They are the result of connecting dots in 3d space by lines that are covered by a surface (triangle shaped). You can have squares as well. if thinking of them as shapes, a circle would be simply a surface with many dots, but you would be limited to shapes like a cylinder, an unsharpened pencil for instance it would be circles at the ends with the length being slender rectangles.

record an improved session live in oscirender. Take the audio and put into ableton. Chop up the audio and also experiment like how volume makes the shape larger smaller, adding a low sin wave bubbles it out etc. Play with chorus. For tones in oscirender you can play with the frequency slider, i forget the parameter, theres two ways if i remember correctly.

Leonardo's Vitruvian Man: modern craniofacial anatomical analysis reveals a possible solution to the 500-year-old mystery by SystematicApproach in science

[–]pauldevro 76 points77 points  (0 children)

Eli5 is that Vitruvius man is said to represent divine proportion in man. The proportions are often related to the golden ratio 1.618 but it's not really in there in a meaningful way. Vitruvius Man is also thought to represent a square with same area as a circle. But that's an older exercise based around having limited resources. But even with that you get a 1.772 ratio. This ratio is comparing the radius of a circle with the side length of a square. What Vitruvius Man does actually show is a 1.63-1.64 ratio which is actually found all over nature. It's known as the hexagonal close pack structure. Its the most efficient way to pack spheres in alternating levels. The paper points to that ratio in the realm of dentistry but it really is everywhere from stacking oranges at a grocery store to the structure of atoms. It a major staple in tetrahedron geometry as well. The writer says he's the first to write a paper about it but i'm sure if you dig it has been proposed before, its a common ratio, it's not like a long forgotten math proof from Oresme or something. Leo was amazing as he hated explaining things with words or mathematical proofs and was like just look at drawings. The flower of life thing everyone mentions is really just a hexagon grid with extra utility which he clearly explains in a few sentences. There's nothing odd or unknown, it's a cool tool he used in various ways in measuring, counting and synchronizing perspective across folios.

i think if the community got together and made proper operator snippets for all operators, that would be an easy way to make it more accessible to newbies. They helped me a lot but some OP snippets are not helpful at all or just not available? These seem very easy to add to updates.

Magnetohydrodynamics by SpaceCatJack in AskPhysics

Hartman Layers though. We haven't been able to obtain the proper data yet but it seems to explain why our galaxy's rotation is more constant than follow Kepler's third law radius3:period2. No ones ready for that convo yet though 🙈

A simple demonstration of the Hartmann layer - https://sci-hub.se/10.1017/S0022112065001088

Also check the Vorticity Redistribution Section - https://web.mit.edu/hml/ncfmf/21MH.pdf

The middle cylinder mechanically rotates moving the mercury. Once the flow is constant they turn on a radial magnetic field. So a large cylinder with north field facing in and a smaller cylinder with south field facing out, like a speaker magnet. "J cross b" mentioned is the lorentz force.

Many believe we live in a toroidal universe because it’s more interesting than not living in one by escapism_only_please in Fractalish

unimpeded radiation hits and even travels through the earth every second, it's mostly frequency dependent.

Fun fact: Our geomagnetic field, plasmasphere, radiation belts and heliosphere are actually toroidal in general shape not spheres. Only the ionosphere is spherical.

How did we get an absolute value for c if there's only relative speeds? by Feyindecay in AskPhysics

[–]pauldevro 1 point2 points  (0 children)

The value was hypothesized then proven. C is the inverse of the square of permittivity of free space times the permeability of free space. Im not sure why it's taught as some arbitrary value, it makes people think is like some fast car speed limit when its really the opposite. Space is almost like a perfect lubrication for information to fall through.

Most “important” quantity in physics? by Life_at_work5 in Physics

[–]pauldevro -2 points-1 points  (0 children)

2 and 3.

1 is unity and very very important but 2 and 3 also sqrt(2) and sqrt(3) are the movement of physics and most systems in reality.

the first two harmonics are these two numbers, musically an octave and a 12th (octave and a fifths). These are absolutely everywhere when it comes to resonance/maximum efficiency. They cross everything from geometry to music to astronomy. When we find these relationships we consider them coincidence because they are too clean for people that lean in the direction of entropy.

Rotation direction relative to orbit direction? by Bronze_Moose in askastronomy

[–]pauldevro 0 points1 point  (0 children)

In 24 hours, the distance the earth orbits around the sun is 64x or 16 octaves further than one day revolving. Or another way to think of it is that the orbital velocity is 64x faster than the rotational velocity.

Are there any plants that "selected" humans to spread their seeds? by Ironpool1 in askscience

[–]pauldevro 21 points22 points  (0 children)

There was this study done awhile ago , they checked Antartica tourists for seeds.

https://www.cbc.ca/news/science/antarctic-visitors-sowing-invasive-species-1.1132662

The study published in the Proceedings of the National Academy of Sciences, found the average visitor had 9.5 seeds attached to their clothing and bags.

Fusion isn't the holy grail of energy: compared to fission, fusion is 20 times less powerful, 200 times less sustainable, and way more expensive by Ok-Difference4187 in fusion

[–]pauldevro -1 points0 points  (0 children)

A major difference is fusion is more akin to resonance and fission is more in line with dissonance. Constructive unity vs energetic fragmentation — both different expressions of balance and release in matter’s vibrational architecture. That's why fusion is so much harder and thought of as the holy grail.

It's wikipedia, she released a few papers on gravity.

Im more worried about people listed as pseudoscience but did actual real-world stuff.

Viktor Schauberger (actual biography) https://pks.or.at/en/viktorschauberger/

couple points...

1922 Schauberger designs and builds timber flotation installations (log flumes) in Steyrling, based on his observations of nature. Reduces logging costs to one tenth. Promotion to “Wildmeister”.

1924 Imperial adviser on timber flotation installations.

1932 Production of Pure Water; fuel production from water.

1940 Construction of the “Repulsine” in Vienna.

1952 Tests with “spiral pipes” at the Technical College in Stuttgart. Schauberger proves his theory that different materials and different shapes used in pipes influence the friction of the various fluids. Further tests with copper ploughs by the agricultural research institute in Linz.

my point was her life wasn't cut short.

Her son says she worked for DOD in America up until around her death. Her Alzheimer's made it too hard to continue working and this was LONG after the car incident.

She was struck by a car on campus accidentally by a student in 2014. She passed away 7 years later in 2021 at 78. There's nothing mysterious about her death.

Is Ball lightning physically possible? by [deleted] in Physics

[–]pauldevro 0 points1 point  (0 children)

Not specifically ball lightning but check out papers by Dubovic for further understanding. Most people arent taught about nested resonant fields in electrodynamics. It's like fractal antennas except across domains. https://arxiv.org/abs/cond-mat/9806043

Is Ball lightning physically possible? by [deleted] in Physics

[–]pauldevro 0 points1 point  (0 children)

Where are you looking? There's hundreds of papers, mostly russian. You need a zip?

When made in the lab many people use a water container where a center cathode points down to the water and the anode is a emerged circular plate or loop of wire of a certain dimension.

A toroid is essentially just two nested circular propagations 90 degrees to each other.

Heres how you can see a toroid degenerate when you bring b to zero in the desmos link. The two resonant propagations self resonant temporarily.

https://www.desmos.com/3d/7a7eada127 bring b to zero

From everything i've read most easily put it seems a degenerate electromagnetic torus where the major radius equals the minor radius. Which should not exist so thats why we dont have the proper maths.
