If the universe is fractal what is the point of particle physics? They'll just keep on discovering an infinite number of fundamental particles!

The point is to give engineers and practical physicists something to work with, humanity isn't going to explain the universe, but it's going to die comfortably.

i need help cleaning a microscope, i think there is something wrong with mine, im getting a weird "foggy window" effect when i use my 60x and 100x objectives, im also noticing some "wipe" marks on my eye pieces at the 100x objective that is making it insanely hard to see anything even with immersion oil. what do you guys do to clean and maintain your microscopes?

Nice picture of an alga called pediastrum in the first pic op. You're not really giving much info about the issues you are having. Best to try one thing at a time and check if it made the difference. As for wipe marks... did you mean the eyepieces or the actual lens of the 100x objective. For eyepieces use a cotton swab and swirl it outwards from the centre. If on the objective, most likely not removing the immersion oil properly - use good grade wipes like kimwipes not regular tissues and a bit of ethanol if you got some.

I'm fascinated by the idea of biohacking, diybio. I have never studied bio on pro level, but I have some general knowledge about it and I have a basic set of lab tools and a microscope. What projects would be ideal to start with? I am interested in safe and legal stuffs only.

I wanted to test electrolysis in water at home so I connected a 9V battery into a little test tube of filtered tap water and partially stuck the cap on it so the wires would stay in.
Now I know I'm supposed to get hydrogen and oxygen gas which is happening but after letting it sit a while, there has been a light blue liquid accumulating at the bottom (as seen in the picture I took). I've also been worried that I won't handle the tube correctly and the hydrogen gas will react with the air (boom).
If anyone could explain what the light blue liquid is and how to handle this correctly it would be greatly appreciated.

Yeah, I'm going to say that's about right.
Does anyone have anything to add on how to saftley extract the hydrogen?

I believe that if we were able to peer into the 4th dimension, our 4th dimension, we could see a sort of infinite, flat wall consisting entirely of "gears". There is a flat dimension of "machinery" operating on all the matter in our universe, explaining the expansion of space, the nature of quantum mechanics, and the problem of free-will/causality.
Elementary particles have a 4-dimensional aspect. I don't know this to be true, however I have deduced it intuitively. As Carl Segan notably explained, a 3D object embedded in two dimensions would appear as a 2D slice to its observers, the example being a sphere appearing as a circle. As the circle travels upward, a direction unfathomable to the 2D onlookers, the sphere begins to shrink and disappear, eventually reemerging in another location. A similar interaction occurring in our 3D universe would explain, I can now only assume, all the mysteries of our universe.
As the Holo Universe theory continues to gather steam, it is worth noting that this interpretation of the universe allows their compatibility. I stipulate that the universe actually appears similar to the output of a function computed on a computer, one with a distinct beginning and end. Our reality, our universal computer if you will, would allow for infinite iterations and recursions.
This is similar to the namesake of the Taoists, explained in the Tao Te Ching.
>The Tao is like a well: used but never used up. It is like the eternal void: filled with infinite possibilities. It is hidden but always present.
It makes me happy knowing that there exists some order to this reality. Even if man is unable to decipher it its mysteries fully, it is no less entangled in its all encompassing design.

So, what exactly causes those? A lot of people say it's due to zinc deficiency, but I've read somewhere that it was rather provoked by small traumas to the nails and such. Who should I believe?

Can someone explain to me how the things in the red box are achieved?
I never got how to foil polynomials to the power of three. And if you guys could also tell me what to search up on YouTube?
Thanks

if you don't know the "pattern" you need to follow, just do the polynomial to the power of two and multiply it by the term again.
(x+t)^2 * (x+t)
>>
>>7922704
I end up with x^3 + x^2t + 4x + 4t ..
>>
>>7922697
For any power higher than 3 you'd use this triangle to find the coeficcents of the terms.
For example:
(a+b)^n = (nC0)a^n + (nC1)a^(n-1)b.....+(nCn)b^n
The C's are the reffering to the nCr function that is probably on your calculator but also reffers back to this magical triangle where the n is the row and the r is the position (both starting with 0) e.g: 7C1 = 7
(This is called the binomial expansion btw should you want to do some further reading)

What does it mean? I guess Aut(G) implies G is some algebraic structure, probably a group. and M might be a moduli space.
Thats my best guess.
>>
>>7922670
Automorphism group.
Self isomorphisms, they all have inverses. So Aut(g) is always a group no matter what object you are working with. For example G could be a set, a tolopogical space, a differential structure, a group, ring, feild or vector space.
The cool thing is you can look at a automorphism group and get some nice group theory out of anything you can define an isomorphism for.

Aut(G) is the autism group.

Pi day is coming soon, and that makes me wonder why this number has become such an overused meme? There are so many relevant irrational numbers out there. Why does nobody talk about Phi or root 2, both of which have far more utility for me than Pi ever did?

Because it is very basic, and everyone learns it in school.

it's the first fundamental mathematical constant that people learn in school, and most people don't know any others besides pi

It's just the folly of PEMDAS, I guess multiplication technically comes before division in the acronym so fuck it, the top calc is right
