What are the chances that if alien life exist on different planets, they are similar to our own flora and fauna?
Are some features universal, due to the laws of physics or convergent evolution, regardless of which planet they evolved on? ie: alien organisms that need sight for survival will usually develop eyes that would be functionally and structurally similar to various eye types we can find on our own planet?
Obviously, it's possible to use echolocation, rely on a sense of smell, or not need eyes at all due to living underground or caves, but considering that most animals and even plants do have eyes or at least photoreceptors points toward the logical conclusion that sight greatly improves the chances of survival. Well, more like input and information of the environment to be precise, but let's move on.
So, with that, can it be said that if we visited a different planet and there was life on it, it would be logical to expect to find organisms that are remarkably similar to our own?

If they have sight, it would he optimized to the black body spectrum of their star, so maybe they could be able to see in infrared or UV but not in our visible range. They could also "see" with some kind of radar or sonar instead.
Touch and smell won't necessarily be the same as ours. Maybe they have a combination of both or even something totally different to understand their interaction with the environment.
Their size couldn't be too big because of the square cube law, and also not too small because you need a minimum amount of space for a "brain" analogue.
They could have a symmetric shape (for example most animals on earth have a two fold symmetry, left and right) because it's just simpler than being asymmetric, but I wouldn't bet on this one.
The thing that interests me the most however is if their evolution process is the same as ours, ie survival of the fittest. It would be great if it's something different.

I think it's safe to say any intelligent life we find will say their star is white and that they use base 10.

>>8923242
Regarding the size part, I'm excluding possible mega creatures a la Solaris sea and also swarm civilizations of mini individuals who have no free will, like ant colonies. Both of these could actually be possible.

Definitely programming, I fucking hate that I cannot get into it for some reason.
Not sure if it's because I'm NT or something, can get into math but not into programming.

Greetings /sci/,
I'm spending this summer brushing up on my pre-calculus skills as I re-enter university. I did fine in high school, but I hardly remember anything because it was an easy class. I want a book that is challenging in pre-calculus methods because I want to get the basics so well so I never forget it again. Plus, I want a book that will help develop the ability to apply math to practical applications, types of problem-solving, etc.
There has to be some combination of depth, quality/quantity of problems, and overall readability/understandability to the point where I could start thinking about competition math problems if I so wanted to (but of course, the realistic goal is to develop enough mastery to have an easier time in calculus 1/2/3, linear algebra, DifEQ, statistics, probability, etc.). I also want basic coverage of vectors, matrices, probability, combinatorics, etc., which is something that some precalculus textbooks neglect.
I see some names thrown around here, like Precalculus Mathematics in a Nutshell by George Simmons and Basic Mathematics by Serge Lang, but I've found that while those books are better than your average high school fare, they're lacking according to the standards I set previously. I found one free book that seems to be decent: Pre-Calculus - C. Stitz & J. Zeager. A free copy from their website can be found here: www.stitz-zeager.com/szprecalculus07042013.pdf
What do you think /sci/? Also, what resources would you recommend for somebody looking to brush-up and maintain familiarity with physics (force, energy, work, and electric charge) for a chemistry-oriented class?

Hey /sci/ if the earth is flat than why don't planes flying in a straight line just fly off the curve of the earth?

That would be the case if the plane had infinite velocity or if there is no gravity

If the earth was flat then all gravity would pull towards the center of it instead of straight down, no?

Ok, I'm a nerd making a game and I want it to be logical that the cartridges used in the guns in my setting are oversized.
What can be used as a solid charge in ammunition that would function like black powder but need to be used in larger quantities?
I know magnesium burns too slowly to work as a propellant, so what do you suggest? It can be a fictional naturally-occuring element, but I need some properties outlined to make it at least believable, as I'm not a geologist or anything.
Help me, sciencebros.

Ok, maybe I should be more specific. This is a fictional world with limited manufacturing capabilities. I have some simple revolvers and everything else is basically bolt-action single-shot. What properties does a naturally-occuring material need to have to be used as an effective propellant?
This is not a debate about how much cooler one ammunition type is over another. It's about propelling ball-ammo cartridges from unrifled barrels hard enough to fuck up metal armour.

is there really any physicist that could explain Double-slit experiment paradox. How electrons can behave like wave? And when there is an observer, how can they behave like matter? do electrons have any conciousness? or they are coded by "them" to trick us and make us not to find the universe's bug. (is universe simulation?)

First, learn what is meant in this context by "observer". Second, take your meds. Third, there are no particles, everything is waves and fields.
