I have been researching for quite some time on vaccines. I have read both sides of the debate. And yet only one fact has been made clear to me; no one has a clear source document. It's always second or third handed information, and I'm honestly getting tired of it! How can I form an unbiased opinion if I keep getting my information from a questionable source?

So /sci/, are vaccines safe and what are your sources?

Arent Psychopaths/Sociopaths just predatory humans? Similar to how some animals of the same species have different personalities, aren't people with capacity to violence still part of nature instead of against it?

One could argue that its all about Nurture and not Nature but it still doesnt fully explain how each person's tendencies differ from one another, if I were to ask you to explain Psychopathy without resorting to Psychology, how would you explain it?

My take on it is; its Nature's way to trim the herd by introducing these 'anomalies' into the population, the population itself is kept in check, it is, for me, Nature's weird way of enforcing Natural Selection, Psychopaths, when interviewed which type of people are their preferred targets to victimize usually say the following; "The smaller ones, the passive ones, the weak-looking ones, the old, ones who look like they cannot protect themselves" none of these sound like good human specimens, and on the other side of the spectrum, everytime these 'anomalies' strike, people become more vigilant, defenses are rung and the whole population unknowingly becomes stronger

You are implying that antisocial personality is something that was brought upon man by design. It's just a mutation that arose sometime in evolution and survived due to its socially adaptative nature.
>>
>>8671793
Why do you feel you need to explain psychopathy through evolution? Making these claims are pure speculation. Remember, you don't have to positively give explanations for fitness. As long as it's not detrimental. I also think when it comes to individual differences you have to remember that since these traits will exist on a distribution, you don't necessarily need to appeal to evolution. Psychopathy is just on the tail end on a continuum. As long as it's not detrimental.

Question:

What is the volume and area of a 2,5-dimensional "cube" with a sidelength of 1 meter

So every side is 1 meter long, every dimension independent (vectors zero in some dimension will never approach that dimension), and each dimension is orthogonalized.

What is the logical reason we can't have decimal dimensions or negative areas or lines with non-zero volume? Because our language is limited and we are brainlets who can't do anything creative? Because fundamentally there CANNOT EXIST a cube of 2,5 dimensions? Even God couldn't make one.

Well, dimension is a mathematical concept. That means that dimension means what you want it to mean. We define it.

You can have objects with 2.5 dimension, if you define dimension to be "fractal dimension". But you can't have a cube of 2.5 fractal dimension because in fractal dimension you first draw a curve and then quantify its dimension.

In the definition of dimension in which cubes make sense, dimension can only be integral. Because a cube is a regular parallelepiped, and we can only talk about parallelepipeds in the usual definition of dimension.

Buuuuuuuuuuuuuuut.................................

That is the geometric definition of a cube. You could also simply redefine a cube for fractal dimensions.

For example, define a 2.5 dimensional cube as being:
A 2.5 fractal-dimensional curve that looks kinda like a cube if you "zoom-out" a lot.

There you go. Now go play and find the area of the different 2.5 dimensional cubes you will find.

>>8679841
https://en.wikipedia.org/wiki/Menger_sponge
Here, this could possibly be a cube in fractal dimension

It is of dimension 2.726833 so close enough and it kinda looks like a cube, so define it to be a fractal-cube.

As for surface area and volume, it has infinite surface area and 0 volume. There you go.
>>
>>8679869
>Dimension is a mathematical concept... we define it
Nature defined it; we just happened to observe it. But could life exist in 2,5 dimensional world? Or 8,1123124151 dimensional world? Or "red, dog dog bark" -dimensional world?

Okay so I got a way to have 2,5 dimensional object in fractal dimensions. Now I want to have either
>2,5 dimensional object not using fractal dimensions
>OR proof that no such object can be constructed with using atoms and molecules

hey /sci/ this has been bothering me for many months now and the more I think about it, the more I go crazy because one question leads to an EVEN more difficult one. At this moment in time there are some 6 billion people alive on earth. Moreover, there have been billions alive in the past - before me - and there will be billions more after me. Yet, of all these human beings, there is one individual (from my perspective) that stands out from the rest, that's different from all the others. And that person, of course, is me. Presumably I could have been any one of all those billions. But something determined that I would be on the inside of this particular body. What determined that? How was that association made? What determined that my consciousness would manifest itself in this (my) particular) body - out of all those others?

i understand that everyone (me included) is inclined to believe this but it's bullshit and difficult to part from

you're vaguely describing a "spirit", you're describing that thing that seems to make you "special" and nonalgorithmic and so on

you don't really exist like that, there's a bunch of cells that create one seemingly cohesive unit; you couldn't have been anyone else you don't exist like that anon just trust

Is it bullshit? Apparently the Chinese are testing it on Tiangong-2 , and the USAF sent up the X-37 with a classified space propulsion test device device.

What's /sci/'s opinion? Surely the Chinese and USAF wouldn't have wasted the money on this if they thought it was bullshit, right?

If it works, what's your theory on how?

I personally like the quantum vacuum based thrust theory; that the radio waves in the thing are actually bouncing off these particles and introducing some thrust into them before they disappear and miss the back plate of the drive.

What if a brother(20) and a sister(18) were left on a deserted island that has enough resources to live indefinitely?
If they are not rescued would it be likely that they would eventually see each other as sexually attractive and then have kids?

Discuss ways we can apply science to better humanity here.

Something vital that many people don't realize is that sex ratios at birth are biased in favor of males. Research has shown that societies with excess males are more violent and chaotic, since men who cannot find wives and settle down are more likely to commit crimes.

A basic thing we could do that would drastically improve society would be encourage sex selection of females during IVF. We could also discourage abortions in women carrying female babies. This would result in a sex ratio closer to 1:1, and thus a happier and more peaceful society.

Thoughts?

I started a Discord with a similar theme to this, though it specifically focuses on resolving issues with human relationships - heavily tying into the issue of sex ratios I mentioned above, but also speculating about genetic engineering so as to produce women (or men) with more congenial personalities.
