>tfw you realize that your failure at math is due to a misunderstanding of the order of operations
I just found out today, after finally deciding to go back to basics to figure out why I suck at math, that you go from left to right in multiplication/division and addition/substraction. I always thought multiplication took precedence over division and addition took place over substraction. No teacher has ever noticed that this is why I got math problems wrong.
Thanks public school education.
>Thanks public school education.
This is your own fault, not your teachers.
There are textbooks there for you to pick up and read. Your exam results reflect your performance as a student, saying that your teacher or school was terrible means nothing to the person looking at your transcript.
And yes, I went to a public school myself and scored the maximum grade and I'm now studying at a world top 50.
If God is an illusion invented by DNA to prevent us from gping suicidal, then why would genes let us discover them?
Honest question. Why does the area between the scrotum and the thigh smell so bad? Every time I rub my finger through that place and smell my finger really carefully it smells intensely acidic.
Can free will physically/biologically exist? By free will I mean making conscious decisions.
The Libet experiment shows that some (maybe all) of our decisions are made subconsciously, before we are consciously aware of them.
I'm asking from a neuro-scientifically viewpoint, please keep philosophical discussion to a minimum.
>Can free will physically/biologically exist? By free will I mean making conscious decisions.
In the colloquial sense we can make "conscious decisions" insofar as we are "aware" that we're doing so. However that doesn't entail anything dualistic or mysterious, so to speak, about this process we call "consciousness". Moreover, it doesn't imply that such conscious decisions result from the agency of a "free will" if by "free...

Anyone interested in tutoring an ai? You give it a url, it takes the words from it, asks you questions about the words to ascertain their usage/meaning, and tries to tell you what the article was about. The idea is that he'll get better as his vocabulary (a list of classes containing lists of synonyms, information about grammatical usage, etc) improves. This is a screencap from a test with nyt.com

Imagine you've a mountain with x meters. Upon the mountain, there's an antenna with 20 meters. Anyone, in front of the mountain, is watching the antenna, forming a 36 degree angle. What is x equal to?
Are domes a meme?
Like if you wanted to house people on a relatively hostile, barren planet that rhymes with "cars" would you be better off just building a fairly conventional boxy building?
I imagine a dome would be able to better resist structural erosion due to its already smooth shape, and it would also be more earthquake proof than a box because its shape is widest at the base and smallest at the top like a pyramid.
Then I'm curious why in extreme environments on Earth domes still aren't particularly popular but boxes are rampant.
In particular that OP pic is the South Pole station where they demolished the dome and replaced it with a box, and of course there's Whittier, Alaska which is basically a regular apartment building standing alone out of the tundra.
What's the Rudin of linear algebra?
First time poster. I'm a /g/ man normally.
There was a question in a book I was reading about how many single-lines would be needed to connect each computer in a 5 computer network to every other computer. I was wondering if there was an easy and way to express this relationship that holds true at any scale.
Here are 3 images showing my work. I'm wondering what type of math this is, and what education level it's consistent with.
What does /sci/ think of this?
Ok guys I need an advice.
1st year PhD student here, asymmetric organic synthesis.
My supervisor went mad, she expects me to carry out research in three big projects simultaneously. She keeps asking me everyday about the results but it is impossible to do three things at once in the lab. When I told her that it had no sense for me, she replied that I had to learn into multitasking. In my opinion it is much better to finish project A and then go to project B. She thinks it's better to do it simultaneously. Any advices?
What's his name, /sci/?

How come there are only 3 possible explanations for abiogenesis, "Primordial Soup" "Replication First (RNA World)" and "Metabolism First" and they have all been disproved.

What is the best calculator /sci/ uses to solve mathematical problems?
Hey guys, today the physics prof. asked us this question and I have no idea how to answer it.
>If the UK switched from driving on the left to driving on the right, would a day be longer or shorter in the UK?
We don't have to calculate anything, we just have to answer longer or slower with a brief explanation.
how did you master control engineering? your own project? books? any tips?
It's alright, but kind of heavy reading (at least for me it was) and I had to look for applied (dumbed down) examples elsewhere. The book is heavily referenced so I guess that's something. You can probably find it for free to download on the Internet and see for yourself, but I don't recommend doing so because that is illegal.
>Computers are entirely made from two particles: zeros and ones.
But this isn't true at all. Absolutely incorrect.
The hardware. It affects the way how those zeros and ones are interpreted. They are interpreted *differentially* based on context. The differential interpretation is based on different properties of matter in the hardware.
It would be *impossible* to make such complicated system out from only zero and one.
Why are scientists trying to unified theories? Why can't they accept that universe could...

No, it's the software (incidentally also 1s and 0s) that affects how they're interpreted.
Stop being a fucking pleb.
Moreover a unified theory just means that you have been able to express all of your different theories as special cases of a more general theory.
I recorded 3 video animations for trigonometry. I was hoping you guys could check it out.
There is no talking and i use basic graphics to teach trig fast and in a fun way.

Who here /cityplanner/?
What alternatives are there for roads and highways. One of the biggest problems overlooked in today's world is congestion of cities and time wasted in traffic. Not to mention, pollution, noise pollution and a big contributor of stress.
Thinking ahead, populations will increase and congestion from suburbs to the city and vice versa will inevitably get larger and larger. Are there alternatives to roads and transportation of people and what can we do to fix this?
Move the sidewalks up 1 story, more ground space for driving now.
Stop letting people park on the fucking side of the roads
Auto driving cars so you don't need parking lots everywhere.
Elevated tracks for light rail
Or just legalizing light flying vehicles over urban areas.
in what way was the eugenics movement in the 1920-1930s wrong? It seems like the modern welfare state and modern medicine simply encourages those less intelligent and with genetic flaws to breed more.
Why shouldn't we try to improve the general genetic health and intelligence of the human race by say sterilizing the bottom 1-2% every year?
>in what way was the eugenics movement in the 1920-1930s wrong
>much of the original movement was not aimed at African-Americans. According to Leon, the system of racial segregation in the U.S. was such that most eugenics advocates did not perceive a "threat." Rather, it was aimed largely at the immigrants from southern and eastern Europe who came to the U.S. in great numbers between about 1880 and 1924. These were largely Italians, Poles and Slavic peoples.

How does one get into a career in neuroprosthetics? I mean, this field must involve teams of surgeons and neuroscientists, right?
Which undergrad program should I go into? And where do I go after that?
it just not fair that you can just die from one moment to another from brain bleeding. it doesnt matter who you are or how young, healthy you're.
its not fair
It's a crushing realization. Not as soul crushing as actually experiencing a stroke out of the blue and becoming and half-retarded, which IMHO is much worse than just dying. Aneyrisms are bad, but brain damage is horrible.
Also yeah, this too me a while to realize too, but the brain is just tissue. It's part of the body. It will bruise and bleed and die like anything else. It degrades with stress factors and age.
It's a fact. Death is inevitable. Sorry.
Well, you can also die at any moment from a falling meteorite, or being swallowed by a sinkhole, or being crushed by a falling suicide, car crash, choking on an almond, street violence, electrocution, and 1001 ways to die.
You should never take life for granted, talking about enjoying every moment as if it was the last sounds corny and cliché but it's true.
Maybe you died in the time lapse between your post and my reply.
Hey, everyone, I'm hosting a survey on how people view heroin abuse in America. Any and all feedback is welcome.
Former junkie here
I believe you can put whatever you want in to your body and there shouldn't be legal consequences, since I've known junkies who shot up everyday for years and survived yet I can go to mcdonalds and stuff my face for breakfast, lunch, and dinner every day for a month and die from a heart attack.
As someone who no longer shoots up, I think drug addicts are losers, because I know I was a loser when I shot up. Rehab/NA/AA are all useless, all I had to do was move away and when I didn't...
