Why is my brain underclocked?

32 more posts in this thread. [Missing image file: ]
Why is my mind always slow, hazy and overly neutral? Why am I always at least slightly fatigued? Why do I have trouble even with basic algebraic manipulation? Why am I slow and tumbling at adapting to mathematics? Why am I anxious about mathematics? Why don't I fully have time for anything necessary in terms of learning, despite having large amounts of time? Why does everyone else have time despite probably having less of it? How come their minds are so fast?

Why is this man so racist /sci/?

According to this documentary animal farming is (directly and indirectly) responsible for: >Up to 50% of greenhouse gas emissions (more realistic estimates are at about 20%, whereas vehicle emissions account for about 15%) >1/3 of drinkable water usage >Taking up 45% of habitable land >Ocean acidification (through fecal waste) >91% of Amazon rain forest deforestation https://www.youtube.com/watch?v=qGMxKxtsNAI Do you still want to eat meat and animal products? After seeing this documentary I'm thinking of going full vegan, not because it's "morally wrong" to kill animals, but because animal farming is ruining our environment.

Stupid Question Thread

3 more posts in this thread. [Missing image file: ]
You know how this works... Here's mine (see the picture), both my teachers and the mark scheme tell me that "the ring is smooth" is enough to answer this, but I can't see how that makes the tensions equal, the best explanation I could get was that the ring has no effect on the tension in the string, because it's not changed the string. My main issue is that since the different parts of the string are in different positions, they ought to have different components of either the weight or the 1.6N force acting on them which means they'll have different tensions, for some reason that's wrong. Anyone able to help? While the rest of /sci/s questions are being handled, I'll just be reading up on Newton's third law... maybe that'll help :( .

Stirling Engine resources

5 more posts in this thread. [Missing image file: ]
I am a machinist by trade but still very interested in science. I many ways both share some common cores. But to my question. To no avail I have not found any technical resource in regards to stirling engines. I know how and why they work. That is not the problem. I wish to design and build one from scratch without using someone elses plans. I also want it to be effecient (just because I don't want it to be half ass, not to attempt to get off the grid.) I also want to go through all the calculations to make my design. Does anyone know of any resources with formulas, calculations, etc. on stirling engines such as timing, displacement of cylinders, working gas comparisons and so on? Also want it free...or cheap. I have found books that sound promising but some are out of print so are expensive. On a limited budget because of some legal problems compounded by health problems...

Hey, /sci/ I've been out of high school for a couple years and forgotten a lot of the mathematics that I learned, but I want to practice them again. Can anyone recommend some books that can teach me what is covered in algebra 1, algebra 2, geometry, and precalc/calculous 1? I need a refresher on most of those concepts

Walter Lewin accuser interviewed

https://www.insidehighered.com/news/2015/01/23/complainant-unprecedented-walter-lewin-sexual-harassment-case-comes-forward She's a nutcase by her own admission. That said, she appears to have evidence of Lewin's inappropriate behavior in the form of sexually explicit text and photos. Of course, said evidence is not being released to the public. Make of it what you will.

If aliens are real, then how /sci/ explains all the evidence gotten by the UFO guys? I want a honest and smart debate, no namecalling pls. I could show you links to said evidence, but is mostly long hour conference videos. Just look up project camelot. I'm just wondering, if shit isn't real what compells people to become whisteblowers. >huh duh isn't science. I'm looking for scientific arguments as to why conspiracy theories on UFO aren't real.

How can we calculate the perimeter of a circle when pi has an infinite number of decimals? How come the perimeter is not infinitely long?
