plants evolved from first multicellular animals, thats why both are multicellular

fungi did this too

multicellularity began only once

this also explains why all three have so similar form:

>primitive cnidarians look like plants
>fungus look like primitive animals altough non moving
>plants resemble the animals the most
>first multicellular animals branch like trees

what went different is that plants have those chloroplasts to use light as a source of energy, this didnt happen in fungi or animals

the chromosomal DNA (not inside mitochondria) was at first the same for animals, plants and fungi, and this DNA is what creates the form, hwich is why all three look like plants

much much later evolution gave a head region to animals (fish, insect) and they became radically different from plants and fungi, in form
>>
Plants are incredibly intricate. Imagine if you needed adaptable survivability without getting up and moving. Also, the fact that they utilize sunlight is responsible for all other life to not have to. My favorite factoid is how it's almost certain that desire for alcohol probably springboarded agriculture. Coffee gave a bump in mathematic discovery, and psychotropics likely sparked multiple religions. Plants are more in charge than we think.
>>
>>16841082
>multicellularity began only once
Nope, it's happened many times. Eukaryotes probably just evolved once, and the common ancestor of plants and animals was a single celled organism, one population then eovled with a cyanobacteria, which became chloroplast. Then both groups evolved multicellularity multiple times over.

The jump from prokaryote to eukaryote seems much harder than eukaryote to multicellularity.
>>
>>16841082
theres a single cell organism that looks like a plant and can reach 10 ft long

explain thsg

Earth is about 4.54 billion years old. The average day length has increased over time due to tidal friction. Early Earth rotated much faster, estimated 5 to 6 hours per day.

Using a rough integration of changing day length over geologic time:

~4.5 billion years ago: ~5 h days ~1,752 days per year

Today: 24 h days 365 days per year

Average across history: about 900–1000 days per year

Total rotations ≈ average days/year × years = (≈950) × (4.54 × 109) ≈ 4.3 × 1012 rotations.

Two counter opposing vortices of Aetheric pressure convergence lock in at an incommensurable angle/ratio to one another. Think 2 fibonnaci spirals meeting toward. Center point. They can never resolve toward the center (due to the infinite repeating nature of the golden ratio). Instead, they continually revolve around the center, attempting to resolve, but end up self stabilizing in a coherent oscillatory pattern, which is perfectly fractally self similar and harmonious at all levels. They reach harmonically coupled perpetual dynamic equilibrium.

This is some sort of circular reasoning. Math is math. We can use it to describe things we observe. You're suggesting physics (theory) can somehow suggest new types of math (language). That's just wrong.

bro you have bigger fish to fry if you wanna "return"
like, how are you gonna get a job?

so tell me: what is the yeild if the bottom one was 2.5 miles away from the cameraman

Alright, let’s tighten the estimate with your new distance: 2.5 miles (≈ 4 km).
Step 1: Fireball size at 2.5 miles

At 4 km, the apparent fireball in the photo looks quite large compared to nearby buildings. If we assume the fireball subtends ~5° of the camera’s field of view (a reasonable guess for how dominant it looks):

Angular size: 5° = 0.087 rad

Physical diameter: D≈d⋅θ=4,000⋅0.087≈348mD \approx d \cdot \theta = 4{,}000 \cdot 0.087 \approx 348 \,\text{m}

Step 2: Yield scaling

Empirical scaling laws (from U.S. test data) suggest fireball radius RR scales with yield YY approximately as:
R∝Y1/3R \propto Y^{1/3}

A ~350 m fireball diameter (≈175 m radius) corresponds to a yield in the tens of kilotons range.

>The P versus NP problem is a major unsolved problem in theoretical computer science. Informally, it asks whether every problem whose solution can be quickly verified can also be quickly solved.
I don't understand why this is such a huge problem. Isn't the world full of things that obviously constitute solutions to certain optimization problems, merely by virtue of their existence? Things that attest to their own fitness with respect to reality's complex criteria, because they logically could not exist otherwise? For example, you hardly need any computations to determine that terrestrial life solves the problem of maintaining its own structural integrity over time under terrestrial conditions, meanwhile producing such a solution involves a monumental amount of computation no matter what.
>>
>>16840504
Terrestrial life need not to be optimal in any way, only to be good enough. There are many aspects of the human anatomy that is deeply suboptimal but good enough to see a new generation brought up.
>>
>>16840615
>Terrestrial life need not to be optimal in any way
That's not the point. They represent acceptable solutions to a myriad nontrivial computational problems, which you can deduce immediately from their mere existence. I'm sure this doesn't count for whatever reason. I'm just waiting for some compsci fag to explain why not.
>>
>>16840504
>>16840627
>They represent acceptable solutions
Okay, how will you create an algorithm that can verify any solution? So if it's terrestrial life, it'll output true, but what if it isn't? Your verifier will need to be able to take in any input, regardless of whether it exists in the real world or not, and output yes or no for if it's a solution to your problem (in this case it's whether it can maintain its structural integrity?).
Your issue is that you read the informal definition, intuited something you think is an understanding of the problem, and didn't read further. Here, "quickly" isn't some vague opinion of what you think is fast, but refers to a rigorous mathematical definition. In computer science, the runtime of an algorithm is defined with time complexity, often expressed in big O notation which has a formal mathematical definition. In the P vs NP problem, "quickly" refers to polynomial runtime (i.e. the time it takes the algorithm to run is bound by a polynomial function on the size of the input). The set of problems that have a solution algorithm that runs in polynomial time is called P. The set of problems that have a verification algorithm that runs in polynomial time is called NP. NP-hard problems are the problems that every NP problem can be reduced to in polynomial time (i.e. if you have a polynomial time solution to an NP-hard problem, you can use it to create a polynomial time solution for any NP problem). If a problem is both NP-hard and in NP, it is referred to as NP-complete. A famous example of an NP-complete problem is the decision version of the traveling salesman problem. As you can tell, all NP-complete problems are essentially "equivalent" so if you've found a solution for one, you've found a solution for all NP problems. However, no such algorithm has been found yet. Nor has it been proven for any NP problem that its optimal solution has greater than polynomial runtime. So the P vs NP problem remains open.

Handwriting notes helps. My main way of doing it is reading 1 page at a time, then doing something else that I can do on autopilot, like some cleaning or organizing task, while I mentally review what I just read. I'm at work right now reading about operating room prep/sterile procedures from the textbook in-between washing tables and countertops, and sweeping and mopping.

I also spend a lot of time actively trying to recall the chapter I'm trying to solidify in my memory as I'm driving. This can be frustrating because if I can't recall one little thing, I can't whip out the book and look it up while driving. Anyway, yeah, just keep trying.
