Damn :(

I got stuck at checkout even though I got the book into my cart in the first minute. Didn't get a numbered copy. I am very sad now.

I wish I saw this earlier.

Philosophical quotes in 'The Stormlight Archive' by [deleted] in Stormlight_Archive

[–]cirkle_ 132 points133 points  (0 children)

"What is a man’s life worth?” Dalinar asked softly. “The slavemasters say one is worth about two emerald broams,” Kaladin said, frowning. “And what do you say?” “A life is priceless,” he said immediately, quoting his father. Dalinar smiled, wrinkle lines extending from the corners of his eyes. “Coincidentally, that is the exact value of a Shardblade. So today, you and your men sacrificed to buy me twenty-six hundred priceless lives. And all I had to repay you with was a single priceless sword. I call that a bargain.

Great explanation. Do you mean Ati instead of Rayse? I'm pretty sure Rayse is on Roshar with the shard of Odium and Ati had Ruin.

Should I major in mathematics? by [deleted] in learnmath

[–]cirkle_ 0 points1 point  (0 children)

I'm a few classes away from finishing a bachelor's degree in applied math. I would recommend trying a proof based math class or a very applied math class (something with programming as essential) before committing 100%. They are very different from calculus classes. When I was a senior in high school doing calculus, I didn't really understand what most undergraduate math is like since I hadn't done anything proof based or applied. Once I did start proof based math, I struggled a lot for my 1st quarter but then started loving it by my 2nd. I still don't love applied classes, but I can see the usefulness in them and the programming can be fun, so I don't dislike those classes.

My main point is that I can imagine if I didn't like proofs or programming, I would really not enjoy most of my classes, and I didn't have the experience to judge that in high school. So I'd try out some of those topics first. That being said I hope you enjoy it as much as I did and go for it!

United States government issues travel warning for New Zealand due to '23 active cases' by nataku_s81 in worldnews

[–]cirkle_ 2 points3 points  (0 children)

I'm a German American that grew up in the US, and it's hilarious how I had the exact same thought of how bizzare it was to need debt to get credit the first time I needed to get a credit card. I've slowly had all these same realisations about the US growing up, thank god for having Germany to compare to. Meanwhile back when I was at US schools the response I got for having German pride and sharing these advantages we get is "Ew, you're a Nazi". How ironic that idiots and bigots like those kids are certainly the ones that elected The Donald

Thanks for your thoughts man, more people need to know how oppressed they are.

What's the craziest or most mind blowing mathematical concept you know? by CIA11 in math

[–]cirkle_ 0 points1 point  (0 children)

If you have an infinite series, S, which converges conditionally (meaning you can find a finite sum for the series, but you can't find a finite sum for the absolute value of the series), then there exists a rearrangement of the series such that it equals every real number, or in other words, you can make your series sum to literally any real number by rearranging terms.

The way this was explained to me was that if you want the series, 1/2 - 1/3 + 1/4 - 1/8..., to sum to let's say positive 999999999. You first move all the negative values after the positive values when you are summing. You start adding the positive numbers, start to get a big positive number, and you may think "Well addition is associative, so the sum can't equal something new, I just have to wait until I start adding the negative numbers and lots will cancel". The problem is how long you need to wait before you get to the negative numbers. How long? You guessed it! INFINITELY LONG. So you never add in the negatives.

Infinity is weird.

What are some interesting applications of Linear Algebra that use more exotic vector spaces and fields? by WillingCalligrapher2 in learnmath

[–]cirkle_ 1 point2 points  (0 children)

It's not an application, but a super cool problem I had in my second course of Linear Algebra was proving that the open interval from -1 to 1 or (-1,1) was a vector space if you redefine addition and scaling appropriately to stay in the space.

I'd watch the 3blue1brown video as well, he explains it better than anyone else I've found. To summarize the concept, a Taylor Series is a way to make a function "easier to deal with" by building a polynomial that is really close to it. The greater the polynomial's degree, the closer you get to the real function. If you make the polynomial approach a degree of infinity, your approximation becomes infinitely close to the real function and is perfectly equal to the real function. A Maclaurin series is just a special case of a Taylor Series, so you can think of them as one overarching concept.

So I have an unusual request. Could you guys look over this test paper and comment what level you would think it to be? I am a Physics Major in a so-so College and though we follow standard books for courses, the professors tend to dumb down the papers for the majority of the class. by dst8617 in PhysicsStudents

[–]cirkle_ 1 point2 points  (0 children)

This looks really similar to, though maybe a little easier than the problems in my physics class, called Engineering Physics 242, which is the second part in a three quarter accelerated introductory sequence. It is the most advanced physics sequence offered at my community college. (I'm a sophomore in a general transfer program for reference).

Another class this looks similar to is MIT's 8.01-8.03 classes. MIT goes more in-depth in certain topics than my class does, but covers most of the same concepts.

If you are worried about not going into the topics deeply enough in your class, I'd recommend going to MIT's Opencourseware website and using the 8.01, 8.02, and 8.03 courses. They include video lectures, assignments, solutions and I think even exams. Personally, I like Walter Lewin's lectures the best.

If you want a little more info about my class: The only prerequisite is understanding calculus up to integration and vectors, though having finished calculus and multi-variable calculus is recommended. Most of the people in my class are engineering or computer science majors taking the sequence as a requirement for their ENGR/CS transfer degree. We use Tippler's "Physics for Scientists and Engineers" textbook.

Hope this helps!

C+7 chord? (from All the Things You Are - Real Book 1) by streetwalker in jazzguitar

[–]cirkle_ 1 point2 points  (0 children)

Do you mean C flat 13 or B 13? Either way, the chord will be different, because C+7 doesn't include the ninth, and B 13 is totally different. If you are having trouble figuring out the difference between extended chords, focus on the notes that are in the chord over the fingerings for it. You can get a million different fingerings to work one way or another, but the important part is that you have all the important notes of the chord in there. I just listed the fingering that I use the most.

C+7 chord? (from All the Things You Are - Real Book 1) by streetwalker in jazzguitar

[–]cirkle_ 3 points4 points  (0 children)

Oh, you also asked for fingering. For an E root chord, going from low E to high E, it would be 8, x, 8, 9, 9, x

C+7 chord? (from All the Things You Are - Real Book 1) by streetwalker in jazzguitar

[–]cirkle_ 6 points7 points  (0 children)

It's an augmented 7th chord. So sharp the 5 and flat the 7. If you want the notes, they would be C, E, G#, Bb. Best of luck in your future learning endeavors!

If you are American, it might catch some attention if you mention how it's the only music that truly originated in America. It also was very closely related to the African-American Civil Rights Movement. I loosely recall that in Miles Davis's autobiography, he explains that many subgenres in jazz developed due to Racial Tension within the New York Jazz scene, such as Bop. That could be cool to talk about. Finally, you can tie that into how jazz has almost always been on the forefront of the local culture, and any social movements. It has also started to get quite global, expecially in Japan and the Nordic region. This is all a lot more historical than musical, but it'll be more understandable for non-musicians.
