🧵 plants and animals have same origin
Anonymous at Sat, 26 Oct 2024 05:54:39 UTC No. 16450106
heres an idea: animals did not evolve to mimic plants (some primitive animals are very plant like in behaviour even if they have nerves they pretend to be plants) but plants and animals came from the same MULTICELLULAR ancestor
not single celled
multicellularity evolved twice: one is mushroom kingdom and second is animals + plants
plants evolved from first multicellular animals
why does plants have different mitochondria then? because an plant like animal ate some single celled creatures that became its power source
then he omitted his animal mitochondria completely and became solely relying on the new photosynthetic mitochondria taken from a creature resembling modern volvox
this happened in an ocean and it happened 700 million years ago
higher developed plants make branches just like primite plant like branching animals who doesnt have a well formed body plan
we need to stop comparing mitochondrial genes together and start a project of investigating non mitochondria DNA of plants and comparing it to non mitochondrial DNA of most primitive animals

>In this world there is a pleasure of the intellect, which is satisfied in science, and a pleasure of the heart, which consists principally of the fact that human beings mutually ease the troubles and burdens of life. But if it is the job of the highest being to shape creatures on special spheres and to let them exist 80 or 90 years in order to prepare such a pleasure for them, then that would be a miserable plan. Whether the soul lives 80 years or 80 million years, if it perishes once, then this space of time is only a reprieve. One is therefore forced to the view, for which there is so much evidence even though without rigorous scientific basis, that besides this material world another, second, purely spiritual world order exists, with just as many diversities as that in which we live—we are to participate in it.

If there are an infinite number of natural numbers, and an infinite number of fractions in between any two natural numbers, and an infinite number of fractions in between any two fractions, does that mean that there are not only infinite infinities, but an infinite number of those infinities? And an infinite number of those infinities? And an infinite number of those infinities? And…(infinitely times. And that infinitely times. And that infinitely times. And that infinitely times. And…) continues forever. And that continues forever. And that continues forever. And that continues forever. And that continues forever. And…(…)…
How do you define the natural numbers without infinity?

I do not understand the purpose of mathematics as a subject. It makes no sense for schools to unload all of the actual abstract thinking into one class and then essentially have everything else be variations of rote memory and reading. This is an inherent imbalance and kids are completely right in thinking math is the worst because IT IS.
Even medical / law grad courses don't amount to anything more than reading and memorizing things, whereas an entry-level math class for a PhD would kill the average boomer who never needed to go beyond simple Algebra. Half of the American education system ITSELF cannot solve pre-Algebra questions without difficulty and the vast majority of high-level programmers admit they never have to invoke any of their math knowledge outside of very extreme cases for Linear Algebra. And the whole world just pretends we need it anyways.
Note that I'm NOT suggesting math is useless, just that it's treated like one more class for students to take when it has been proven to be unnecessary for jobs, is not retained by basically anyone in any position of power AND is objectively, verifiably harder than anything else we learn. If you can call modern education "learning" but that's a whole other problem. And no, I will not listen to anyone who claims that science is harder because it just straight up isn't. There is no universe in which that's true, there's just more STUFF to know in science whereas math requires you to fundamentally be able to think in ways that don't have anything to do with the real world.
🧵 I want to teach myself electrical engineering
Anonymous at Sat, 26 Oct 2024 00:04:01 UTC No. 16449746
Computers are black magic and I want to know how the fuck they work.
I'd like to at least have an understanding of electronics on the same level as an undergrad EE student.
My current understanding of electronics is very basic. Mostly just learned from messing around with game consoles and some entry level physics courses in college. I'm a bit rusty on the physics and math too...
Where do I start and what resources should I look at?
🧵 Flourescent Lights and UV
Anonymous at Fri, 25 Oct 2024 22:58:55 UTC No. 16449660
I've been trying to do research on Fluorescent Lights and the UVs they emit, but everything I find is contradictory with other things I find, or has barely any information to it. I've read that fluorescent produces less UV rays than incandescent, I've read that it produces more. I read that it produces so little that its impact won't be felt by either you or the items you own, and I've read that it produces a medium amount that can damage for photos and skin. I've read that the phosphor layer blocks the UV rays, and I've read that it still lets the worst ones pass through.
Is it worth just replacing all the light bulbs and tube lights with LEDs to protect my skin and photos?
🧵 Can we adjust gravity?

If we can make an airplane pull the earth towards itself we can fly easier. Better if we can concentrate gravity in one direction as to generate more force per m3 and avoid shit like it acting like a magnet for everything

Why aren't more people enchanted with math?
It's literally best thing we humans have on earth. And everyone can experience and enjoy it, you don't need any money and can just read the books and experience it first hand. All you need is time.
Math is the only thing that makes life even remotely worth living.

I need to build emp device to destroy some spyware tech (of course I own this tech and I do it only for educational purpoases only).
I am not tech retard and have access and ability to create such device.
What I need to know what should be the technical parameter of this device to fry electronics at close range and not just temporarily disable it.
What should be the inductance and resistance of coil, what should be the voltages on capacitors?
Do you have any links to papers or blogs going into technical details on EMPs?
Do you know equation which can lead me to parameters for device?
