1 KB,
Hey there. So I have ran into an equation I can't solve. It involves absolute values and powers of x.

I've tried going to online calculators but found no aid, except in wolfram alpha, but I don't have access to their explanations. If anybody knows how to solve this, I'd be all ears.

Thanks. OP.

1. Math "trickles down", corollaries fall through from pure to applied and from applied to natural sciences, eventually becoming tools for use in physics, biology, engineering, chemistry, etc.

That's where your stoner bullshit hits its limits.
I have a laptop.
No matter how "virtual" our reality is, the computing power of my laptop is real.
If we're living in a simulation, computing power of my laptop is a subset of the computing power of the simulator.
If we build a holographic universe, its inhabitants might build a simulated universe of their own.
But the ultimate top-end simulator MUST possess a limited amount of processing...

I have some questions. I consider myself very ignorant when it comes to biology in general but DNA especially is a mystery to me.

I've been thinking about how we view creatures and group them. Chimpanzees are apparently very close to us genetically. The 90+% shared DNA thing. So a lot of the genetic information seems to have been used to define the humanoid shape with head, arms and legs fingers and stuff. That last 10% make us human in some way. But could you say that since evolution works. The weaker species die out (neanderthal etc) the more we evolve to fit...

imagine there is a small population with lack of diversity, say a group of aryans, perfect looking on the outside. mutations happen, nothing cant stop that, sometimes they can be reversed, sometimes they remain, they replicate during dna replication etc,...

With chimpanzee we have 1% difference in our genes. What has been told to me, our alleles are quite different however. Meaning that our gene to build toe is in the same place, but the actual building data is very different.

>>7942968
No no no. You don't understand. The genetic material is highly conserved over ALL species! We are genetically 75% similar to the tiny small worm, c. Elegans .

We share genes with Horseshoe crabs even.

I just posted this in another thread. Evolution and natural selection don't work to produce something that works the best or most efficient. things that are selected for just have to work. Biological systems are terribly inefficient and in an ideal world we would have wheels instead of legs.

Let me start off by saying I swear I'm not trolling. I just had a thought:

Okay, so we all know that when you divide by zero it is impossible. Why? Because any number multiplied by zero yields zero; therefore, it is impossible to discern what (this is concerning 0/0 only, by the way) was originally multiplied by zero. But concerning the fraction 0/0, couldn't there be an answer to that? And wouldn't that answer be a set of ALL numbers (any type: real, complex, etc...in a way it would be the largest infinity)? Am I buttfuck retarded? Is this all an indeterminate form is?

Looking for some information about mutation rates in human viruses. I want to ballpark the probability of coding genes being added or altered over time/generations for various genome sizes.

I know very little about genetics and less about viruses, but want to check the feasibility of an idea. Unsure where to start, aside from digging through mountains of research I won't be likely to understand.

Any direction would be appreciated. Ideally just some example statistics and major variables I'm likely to overlook. Thanks

Rationals.png
31 KB,
Is this a bad definition of the rationals?

Considers (-2/-1) since -1 does not belong the the natural numbers, (-2/-1) would not be a rational number and I suppose it would be irrational if we define irrational as the complement set of the rationals.

Still we know that (-2/-1) and (2/1) are the same number and (2/1) is a rational number.

So this number both is and is not a rational number?

Am I the only one that thinks this is a paradox?

Is this definition of the rational common in textbooks? I usually see it defined when both numerator and...

i think it's just referring to the fact that negative quotients -(n/z) are usually thought of as having a negative numerator (-n/z) even though this is purely a formality

What if a parent universe had a black hole that sucks in matter, forming a white hole?

If so it'd explain the big bang and this general expansion of the universe.

This also ties in with the theory that black holes evaporate

Is the universe we know evaporating?

'White holes' would violate even more laws of physics than black holes. Entrophy and thermodynamics are pretty well establlished and whiteholes would shit all over that.
