New post: "Lines and Angles on Square Grids"

Thank you to @annemathswatson for allowing me to share her article. Here Anne discusses the connections & pedagogical implications in a collection of Don Steward tasks.

@GuruAnaerobic @nntaleb It applies to dimensionless data with scale invariance.

In practice, it is nearly always applied to data with exponential growth.

@nntaleb Now, examine the fraction parts of the logs and chop it up into some arbitrary number of intervals and test for uniformity.

[MetaPrep @PrepMeta]

@nntaleb In fact, if the vote/population sizes are on [a,b], let t = b/a and choose a log equal to t/k, and try values like k = 8 where the data wraps around the distribution 8 times. For practical matters, this smooths a lot of situations with convexity in the data.

@tmeddieaz @gorskon Aggregating data is unreasonable? That's quite an interesting take.

Which information there is misinformation?

[MetaPrep @PrepMeta]

@goldgreenlazuli @EduEngineer @ACChaudre @FrancoisBncx Glad to see that we're doing a good enough job of promoting the right information that you're making childish attacks and then blocking. That simply shows the world that you're unable to engage in debate.

Keep it up.

@Belial_spirit @Na67882206 @JJWINAZZ @EduEngineer @axelkahn Do you understand the concept of "strictly better than"?

The above data needs no control group because it outperforms EVERY control group (by a lot).

There is ample demographic data and it even leans toward high risk patients.

@JJWINAZZ @EduEngineer @axelkahn You can call me a liar without cause, but you can also read the book when it comes out. Just let me know who you are so I can cite the man with 12 COVID-19 publications. ;-)

Education with an attitude for improvement.

We approve.

[MetaPrep @PrepMeta]

@edsouthall This is why one of the absolute more important goals of education is to encourage sharpness and discourage dullness. So long as people are curious, education just happens constantly.
