This place is pretty shitty with the "I'm class of 2020 hur durr" and "Pre-Calculus HW Help Thread". Where are the grad students doing interesting mathematical research? This place is 10000x worse with the underage kiddos here. The intellectual depth is lacking.

Why does highschool tell students why math is useful, but not why it can be fun and interesting? It's like the "math is a chore" meme infected the teachers too. Has the education system failed in that regard?

Yes

I had a teacher who tried the "math is fun" stuff, but most people would mostly shrug it off and keep chatting in their cell phones whenever she tried to convince us with talk no jutsu.
I really liked her and the other applied students did too because she really worked on her classes and was legitimately concerned about her students.

The Sun and the Earth revolve each other.

The Sun that hypothetically revolves the Earth is, as significant as, the Earth that theoretically revolves the Sun.

Observation shows that the Sun revolves the Earth.

Evidence can be discovered to show that the Earth revolves the Sun.

We observe an evident phenomenon- and phenomena that can be taken as evidence.

>We cannot capture 'the Sun's revolution' around the planet beyond our immediate senses and therefore there is no physical evidence.

Repetitive comments are a result of evidence-heavy science- i.e. pseudo-science.

Had you believed the Sun revolves the Earth, you would strive to be original as to keep a decent image, instead you hypothetically hit readers with unoriginal perversity.

Does the fact that we have numbers that cannot have their exact value represented in our notation (irrationals, I) show an insuffiency in our number system? Obviously, there was no need for these yet when the Arabs first wrote "1,2,3,4",etc. Would it be possible to start over from scratch with all new symbols, concepts, etc to create a notation system where all these are accounted for? Would it make maths more intuitive and advanced math easier?

Harvard architecture

>Under pure von Neumann architecture the CPU can be either reading an instruction or reading/writing data from/to the memory. Both cannot occur at the same time since the instructions and data use the same bus system. In a computer using the Harvard architecture, the CPU can both read an instruction and perform a data memory access at the same time,[1] even without a cache. A Harvard architecture computer can thus be faster for a given circuit complexity because instruction...

FPGAs with millions of vertical stacks instead of a single bus to the ram are in development. Neuromorphic computing is a thing.

A month or two back an anon asserted that Von Neumann and his friends intentionally withheld most of their ideas from the USA because they knew Americans were just as bad as everyone else. If he's here I'd like to hear more on this.

I suspect Von Neumann's nanomachines were intended as software that would run on a hardware implementation of his binary neural networks. What happened instead was the Americans took their...

Why isn't it standard to immediately test for all bacterial strains that cause infection?

There are extremely many reasons. The most pressing ones are that it would literally take years to test, that there is no guarantee that compound x from the bacterial strain that they are checking for is in the particular blood sample they're using, and that there will be a lot of false positives and negatives.

Give it to me straight, do nootropics have any worth? I hear more about them all the time. I've heard of adderall which helps your attention span, but I don't want that one. I've heard of theanine that lessens social anxiety and when I searched for it I found out there were tonnes more, including ones that supposedly increase brainpower.

We all know winners do drugs lads. Ok, an even better justification is that we already eat tonnes of artificial shit in our food so surely nootropics isn't some freak category?

Interesting. My dad is pretty much ambidextrous. I think he's slightly Asbergers.

You can train yourself to write with your non-dominant hand but it's hard if you're not naturally ambi.
