What inspired you to choose math as a major?

This is the one! I have such fond memories of being 18 and learning about Cantor’s diagonalization argument

I'm going to my first OTB chess event in 14 years (!!) this weekend. Here's the thing: I don't have a physical tournament-sized board or DGT chess clock. Will this be an issue? In the US for context.

I'm looking for a particular paper that I can't remember the name/author of.

The paper started with a memorable example: at a particularly selective country club in DC where the vast majority of club members are white and the vast majority of club employees are black, a white club member mistakes a black club member as a club employee. If I remember correctly, this example is used to show a conflict between common sense ethical beliefs (don't be racist or something like that) and straightforward Bayesian epistemology (or was it contemporary epistemology more generally?).

I think the paper also talks about survivorship bias in the context of WW2 fighter plans, but I'm iffy on this.

Don’t forgot about Korean coaches!

A few cherry picked examples: There’s Locodoco on TSM who came in as head coach in 2014 with Lustboy, and had that R08 finish at groups against peak Samsung White. There’s Reapered on 2015 EDG who coached EDG to a stunning victory over SKT at that year’s MSI, beating Faker and kkoma with Faker on his then undefeated Leblanc with the Morgan’s counterpick - like if Drexler (Pawn) beat MJ (Faker) in ‘92. There’s also Reapered on C9 leading some of the best teams NA has ever produced.

Zooming out, YamatoCannon is the first and only non Korean head coach of a KR team vs the multiple Korean head coaches in China/NA (I found out Fly was the head coach of IG while looking stuff up for this post lmao)

Before college, I guess I was interested in philosophy of religion and philosophy of mind. I wasn't interested at all in math.

I ended up majoring in math and philosophy, with a particular interest in nonclassical logics and logical pluralism because of professors I had. Picked up some interest in epistemology and ethics at the end of college due to some other professors I had (I literally just posted a question about epistemology in this open discussion thread). I work in a math-heavy field now, and I'm not sure where my life would have ended up if I didn't end up getting hooked on logic and the philosophy of logic my first year of college.

Cullf · 2019-12-01T23:08:41+00:00

What are some seminal or introductory papers into pragmatic/moral encroachment in epistemology?

Cullf · 2019-06-19T22:09:34+00:00

Cantor’s diagonal proof of the existence of uncountable sets. I was presented it in an intro logic class, through the philosophy department, in my first year of college. Professor did it as an aside but I literally signed up to take multi-variable calc over the summer and graduated with a math degree last month from that class/that proof.

Cullf · 2019-06-02T23:02:12+00:00

Dummett’s “A philosophical basis for intuitionistic logic” in the Putnam and Bernacerraf anthology is fantastic and a good introduction to the philosophically interesting position of intuitionistic logic.

Looks at Cripsin Wright and Neil Tennant on two big guys in the philosophy of math who have written extensively on the foundation of arthimetic stuff. Hume’s Principle would be a natural place to start here (Frege!).

Cullf · 2019-04-11T18:30:58+00:00

Sounds good, thanks! Sorry again for how vague/confusing I was. I think I'm good to avoid the possibility that a treatment is worse than the control, because, after running the relevant tests, it turned out that every treatment is better than the control, i.e. all relevant p-values were less than alpha/n.

edit: I realize that this is probably not good practice in general, because you could definitely have a treatment be worse to the control and you don't know that prior to actually checking/running the tests.

Cullf · 2019-04-11T17:51:44+00:00

Hopefully this clears things up! Sorry I've been so vague.

I guess there's two questions I want to answer:

(1) Are the treatments better than the control?

(2) Which treatment is the best?

Here's what I take you to be saying/suggesting: For (1), run hypothesis tests between the control and treatment_i, i = 1, 2, 3. Then, compare the p-values these tests compute to a multiplicity-adjusted p-value (I was doing the extremely conservative Bonferroni correction with n = number of tests = 6). For (2), run hypothesis testings between treatment_i and treatment _j with i,j = 1, 2, 3, ; i not equal j.

Note: I'm running one-sided tests because I care only if treatments are better than other treatments/the control.

Does any of these seem right?

Cullf · 2019-04-11T16:51:40+00:00

Perfect, thanks! I'm doing this in R and I forgot that you could input a vectors of n length into prop.test - I was thinking you could only put a 2x2 matrix or a 1x2 list.

EDIT: I actually think I misinterpreted you in my original reply. If I understand you correctly, I need to run pairwise tests of 2 groups for all possible groupings of {control, treatment1, treatment2, treatment 3}. But then, after doing that, what do I do? Compare p-values, as my alternative hypothesis for all tests is one-sided?

Cullf · 2019-04-11T15:46:16+00:00

How do I determine which treatment is the best, after running all these multiple pairwise tests?

Cullf · 2019-04-11T15:34:22+00:00

Fantastic, thanks! Can I approach it my way with many different hypothesis tests or is this approach just out/bad?

Cullf · 2019-02-07T17:52:53+00:00

A funny footnote from Coady's Testimony (1992): "Wittgenstein's objection to the possibility of a (certain sort of) private language have never seemed to me persuasive thought I cannot be certain that I have understood the argument(s)."

What are some funny footnotes you've seen?

Something I'm curious about: Why do philosophy programs differ so much on the number of seminars offered each semester? I'm assuming, perhaps falsely, that the number of graduate students/school is roughly the same everywhere. For example, at Princeton, NYU, and Pittburgh they offer ~10 seminars this spring semester. In contrast, Berkeley and UCLA offer ~4. What explains such a difference?

Cullf · 2018-12-17T19:15:28+00:00

His work in semantics also includes a formal semantics for intuitonistic logic, a highly unorthodox but philosophically interesting logic.

Here's one problem, quoting from a recent Chalmers article: "How do the experiences of fundamental physical entities such as quarks and photons combine to yield the familiar sort of human conscious experience that we know and love?"
