Initially loved him a great deal, considered him a genius and very likeable man then I grew to dislike him, morally ambiguous individual if you read his diaries (waah why did i make the nuke) and he didn't understand philosophy in the slightest.

Why is philosophy, especially philosophy of science, frowned on by so many scientists nowadays?

Latex is the input equivalent of writing a book using Morse code.

So,

2. Are you happy with it?
3. Do you foresee/expect/hope for any improvements?

I can type 10 characters per second. Latex is a piece of cake.

You are complaining because you cannot type as fast as you draw symbols but when you were a retard kid drawing symbols was hard too. Heck, I bet your first integral signs looked like shit and then when you wanted to make them nice you had to do it a little slow.

Just git gud at keyboards, fag.

literally just expand the taylor series you ingrate

If you expand exp(x) in a Taylor series, then plug in x = i*pi, then you get -1

Find the Euler's Formula page on Wikipedia. The Power Series proof under the "Proofs" section is as simple as it gets. You don't need to understand the Maclaurin series, just know that it works. Euler's identity is proved when you substitute pi for x.

>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.

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.

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.

Become aware that you are making subconscious decisions and fight them. Then fight the subconscious decision that tells you to fight your subconscious descision. And so on.

>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 will" we mean something independent of physical causation and the material world. Our will is indeed free to the extent that our body and mind coincide, and hence, to the extent that our overall micro-physiological state (including our CNS) both determines our course of action, and produces and instantiate our "abstract" mental state.
>>
>>8475886
I.e. mental states exhibit free will precisely in the sense that our mind coincides with our nervous system and our nervous system determines how we behave.

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

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?
11 posts and 5 images submitted.

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.
>>
>>8475356
boxes are cheap

domes are strong

Domes are for when you don't have backup options if your building gets damaged.
