You can raise your IQ by taking multiple IQ tests and getting better at them
>Nooo that doesn't count you have to take the test only once!!!
Skill/performance is determined by consistency within the long run, maybe it's time to admit that IQ tests are bullshit if you think that practice is considered "cheating"
🧵 Genetcs for selfish genes
Anonymous at Wed, 26 Mar 2025 22:59:53 UTC No. 16629427
I have been thinking about the concept of selfish genes, as introduced by Dawkins, over the past few days. This led me to the following consideration. From the perspective of a selfish gene, there must be an optimal degree of relatedness, right?
This idea may appear erratic. So, please let me room to explain.
Let’s consider the parent generation. Each parent has a 50% rate of passing on their genes. Basically, yes. However, there is a way for a selfish gene to further increase its chances of being passed on, namely if both parents are related and thus already share a certain percentage of genes.
So, from the perspective of a selfish gene, there must be a trade-off between the harms of inbreeding, such as the activation of harmful recessive genes or a lack of genetic diversity, and the benefits of relatedness through an increased chance of being passed on. Formally, one can write: given a certain degree of relatedness, c is the chance of harmful mutations and recessive genes, etc., while t is the chance of passing on as many selfish genes as possible.
t >> c
How you any idea how formally caculate this?

AYO!
A person on the Moon cannot jump high enough to escape its gravity and go into orbit.
The Moon’s escape velocity—the speed needed to completely break free from its gravity—is about 2.38 km/s (or 2,380 m/s). Even with the Moon's lower gravity (about 1/6th of Earth's), a human can only jump a few meters high at most, reaching speeds of maybe 3-4 m/s. This is nowhere near enough to escape the Moon’s gravity.

Decided to do some libre study all about randomness. True randomness vs pseudorandomness, RNG, PRNG, the metaphysics, and any and all applications of it.
Any suggestions for study material?

I am not formally educated beyond a high school level in America
Does Quantum physics understand where exactly atoms come from, or what causes them to form the specific atomic mass and electron number they need to be considered the element they are?
I know that "intrinsic" forces (as I call them) account for why, say, gravity, or electro-magnetism will always behave a certain way or seek to behave a certain way. This is because of the inherent laws of physics, and by extension, reality.
But why do quanta arrange themselves to allow for certain elements to be created at certain instances?
Can anybody elucidate this for me, a brave and honest fool?

Question for geneticists here. I notice most beautiful eastern video game characters have this downwards pointed top lip (tubercle/procheilon?), and, irl, while you occasionally see it in whites/other races it's way more common in asians. Idk if it evolved from diet, sexual selection, whatever, but it's a subtle but important part of cuteness in asian characters. Just check any game character you like and you'll start noticing it. And conversely it's quite rare in western character design.
I just want to know what this comes from. And also why it seems to sometimes pop up in other races. Thanks.

If we consider that the population reaches a ceiling of 11 billion and later it will decline as world birth rates fall below replacement levels, we can assume that the human species will become extinct before the year 3000.

A question about the nature of time
I was thinking about how time slows as an object approaches the speed of light, and at the speed of light it presumably experiences no passage of time.
There should be an inverse of this - an object traveling so slowly that it experiences all of time at once? That led me to think, the only thing that is not part of the expanding universe is the singularity at its beginning, the source of the big bang.
So I asked ChatGPT a bunch about this, if all of spacetime is compressed into a singularity, would the entire timeline of the universe be encoded within it?
It seems to point to two theories, one that time is a fundamental part of the universe, and one that time is an emergent property.
Another analogy would be that black holes encode information along their event horizon. Let's say the big bang began from a black hole so massive that it contained all the matter in the universe. I suppose it would not be like any we could ever observe, as any black hole within our universe only contains a portion of it (unless there's a "big crunch" in the far future). Perhaps such a massive black hole would also contain its own event horizon at a single point, and therefore all information, including all of time, was encoded at that single point.
The implication of this would be that time, as well as every other interaction in the universe, is analogous to a computer program executing. There are not multiple timelines or possibilities, only one sequence of events which is predetermined from the start. This isn't super relevant if true, because there's no possible observer to decode the information that was encoded in the singularity, at least not one within our universe, and I really don't want to get deeper into thinking about multiple universes, just focus on the one we know.

Where I live, there's an equal chance it's either gonna be 40s or 70s degrees Farenheit at its highest, and a snow day isn't unexpected either. We experienced both a heat wave and a cold wave two years apart during March. November has a similar average temperature, yet it feels more consistent. What gives?

singularity inside a black hole is actually just a portal to another universe the fabric of space time is so warped that it transitions anything that falls into a 5th dimensional space.

2. Syphon the antimatter from the other universe into this one using magnets
3. Profit from unlimited power of antimatter
