Do perfect squares exist in physics?

[mare veen]

Hello, I am a visual artist and currently working on a project about ‘being’. Under the assumption that ‘being’ or ‘to be’ is never square I was wondering if in physics (or astronomy/cosmology/biology etc) perfect squares or 90degrees corners exist. Isn't a square and perfect 90degrees corner only made up by mankind or is it also present in physics?
Anyone out there who can help me? Thank you!

There are many situations where currents, magnetic fields and electric fields are mutually perpendicular or orthogonal. They are related by the cross product of vectors.
The perpendicular axes are not of the same kind but they are at right angles.

Superb, thank you!

Here's another one: https://en.wikipedia.org/wiki/Halite

And do the mathematical models which involve squared distances count?

Thank you! I’m mainly in search of visual/imaging proof.

Geometry and mathematics in general are used to model nature. Whether mathematics itself is natural or invented is an often debated question that probably has no definite answer. You could, in fact, have a similar debate about whether physics is discovered or invented. But that's more the philosophy of science than science itself.

One example of a right angle in nature is the relationship between the electric and magnetic fields in a light wave. Theoretically, at least, they are at right angles to each other.

Also, the magnetic force on a charged particle is at right angles to its velocity.

Thank you so much PeroK. Do you have an image or wikipedia site that hows this? Sorry, a bit new to the subject.

If you google for "electromagnetic wave" and "lorentz force" and see what images come up.

The regular geometric patterns such as circles, lines and hexagons that emerge in nature are termed "emergent properties". https://en.wikipedia.org/wiki/Emergence

Crystal structure is probably the best example which explains why they are given mystical properties by the new age. https://en.wikipedia.org/wiki/Crystal_structure
Most people use common salt, (NaCl), every day, but they do not realize the cubic perfection.

There are also some macro properties where right angles can be seen. For example, if you suspend a weight on a long thread or hair, the thread will form a right angle with the horizon. Gravity works to produce two situations that are orthogonal, one hanging vertical on a thread, the other being the horizontal surface of a liquid.
