What causes people to form relationships with intellectually inferior creatures such as "friends" and "lovers"? (as if love exists, especially love for something as dumb as a woman)
Is it lack of intelligence or can people like this be helped?

Love exists but it's more similar to drugs than most people would accept. Especially in very drug restrictive countries. Notice how the language is twisted so very differently between the concepts :

"falling in love" <---> "falling of the wagon"
"true love" <---> "life long addiction"
"match making" <---> "enabling"
"unhappy love / longing" <---> "abstinence"

The list could probably continue for a while.

As a fun engineering project, I decided to engineer a "prosthetic" hand (really, a mechanical model of the human hand) , but when going through the design process I came across a road bump. Hypothetically, is there a way to have a material (stainless steel) protrude externally from the skin without serious risks of infection or rejection? I'm not a medical student, but I understand that's a concern.

Pic related. Early sketch/part estimation

My guess would be no. People get piercings all the time, which are small and in low blood-flow areas and they're still an infection risk. In something like your hand I don't think you could have a permanent extrusion without constantly having to disinfect it.

Work on controlling the fingers and making them fully actuated. Realize making fully actuated fingers is harder than it looks. It's crap that a kid could make if you don't make the fingers fully actuated with independent control.

We can do that OP, those are called osteointegrated prosthesis, but there is still risk of infection. People with such prosthesis must be careful to avoid risks of infection.
>>
>>8550022
See, I wanted to avoid motors and go for replicating the functions of a hand. The design, hypothetically, would connect to existing residual tendons, and function EXACTLY like a natural hand. Not sure if that's practical, but it will be fun to play with that idea.

>>
>>8552291
the perception of time and how it is perceived is just relative to who or what perceives it.

techically we don't perceive things in a "100% real time sense", due to the amount of time required for the optic nerve to send and process data to the brain. Albeit that this isn't a noticeable difference because the processing of this data is a rather impressively fast process.

Nonetheless, its rather impressive and interesting thing to think about

So help me out here /sci/
Acids are molecules who are able to give off an H+ ion, but what makes such a molecule a strong acid?
Hydrochloric acid just gives off one H+ ion, but is one of the strogest acids there is.
Citronic acid gives off 3 H+ ions, but is a rather weak acid.

In theory one mole of hydrochloric acid dissolved in a litre of water should create a weaker acid than citronic acid right?

So why isn't that the case?
7 posts and 1 images submitted.
>>
"Weak" and "strong" describe only the rate at which an acid releases it's proton. If there is any non-negligible equilibrium where the acid is protonated then it's a weak acid.

Specifically, for the reaction
HA <-> H+ + A-
If the pKa value, where Ka=[H+][A-]/[HA] and pKa=-log10 (Ka), is less than -1.74, the acid is strong. The dissociation reaction is so heavily favored that no backward reaction can accumulate HA molecules.
>>
You need to clarify what you mean by "strong" and "weak". These terms do not necessarily refer to how good an acid is at dissolving things. Rather, they refer to how easily the molecules give up their H+ ions.

Xenophobia is part of your natural animalistic instincts. It's only nature. As long as you don't invent some dumb racial superiority theory to justify it you don't have anything to be ashamed of. People like people who are similar to them.

Any good books that are an intro to neuroscience? Like Hawking's Brief History of Time. Not rigorous, but a very inspiring overview. I kind of like the subject, but I know little and I'd like to read something that gives me the passion to start reading more dry and rigorous texts.
