Everything is Mathicable

The U.N. declared 2013 the year of Mathematics of Planet Earth.  This initiative has now been extended into an ongoing project.  Check out their website for exciting news about upcoming lectures, new PhD. Earth Mathematics programs and exciting new happenings.

Also: with the recent Ebola outbreaks, I figured now was a good time to bring out this paper, which discusses a pretty classic model for disease transmission, applied to the Ebola virus.

If the full thing is too steep for you, you're welcome to adopt the Genuine Mathematical Method for Unfamiliar Paper Readings: skim the intro, skip down to the discussion, and squint at the equations in the middle.

Science And Islam — Jim Al-Khalili [BBC Documentary]

Science and Islam (2009) is a three-part BBC documentary about the history of science in medieval Islamic civilization presented by Jim Al-Khalili. The series is accompanied by the book Science and Islam: A History written by Ehsan Masood.

Hey all- I caught this documentary in a class once and it's pretty neat. It's also a bit long, so if you haven't got the full three hours, the math part is about 48min in.

If you're not already familiar with this super important part of math history, it's definitely worth watching. If you are, you probably won't hear anything new, as it's super brief (about ten minutes).

…mathematics is so rich and infinite that it is impossible to learn it systematically, and if you wait to master one topic before moving on to the next, you’ll never get anywhere. Instead, you’ll have tendrils of knowledge extending far from your comfort zone. Then you can later backfill from these tendrils, and extend your comfort zone; this is much easier to do than learning “forwards”.

Construction of a square from circles.

Pythagorean tree. 

Created by starting with a standard square, then adding two more squares scaled down by a factor of square 2 over 2, then continuing this process, ad infinitum.

My degree was like 99% learning to fail miserably and still get up the next morning.

I just read a proof of the AM-GM inequality based on the laws of thermodynamics. Wow.

The game theory of life

Emily Singer:

In what appears to be the first study of its kind, computer scientists report that an algorithm discovered more than 50 years ago in game theory and now widely used in machine learning is mathematically identical to the equations used to describe the distribution of genes within a population of organisms. Researchers may be able to use the algorithm, which is surprisingly simple and powerful, to better understand how natural selection works and how populations maintain their genetic diversity.

In mathematics, the Weierstrass function is an example of a pathological real-valued function on the real line. The function has the property that it is continuous everywhere but differentiable nowhere.Above is the plot of the Weierstrass Function over the interval [−2, 2]. Like fractals, the function exhibits self-similarity: every zoom (red circle) is similar to the global plot.

Not exactly the degree of simplification that I was hoping for, Mathematica.

Same anon as last time. Sorry my spelling is a bit off but I couldn't stay below the character limit lol. Also I wanted to finish by saying I feel as if I can't or I shouldn't pursue it any longer because I don't feel like I'm "smart enough" for it anymore.

First of all, I do not have a degree in math, but I am pursuing one. Secondly, I do not think you should give up on a math degree. Math skills are not something you are born with; they are something you learn. Even I am not that good at math. But my abilities with the subject are not the reason I’m pursuing a degree in it. I’m pursuing a degree in it because I have an interest in it. That should be the reason why you become a math major. You can relearn the skills and little bits of mathematical knowledge you’ve lost over the years. Anything that can be learned can be relearned. So, if you love mathematics go major in it. I promise that it will be worth it.

Sorry for replying to the second part. I was typing my response to the first part and accidentally hit enter before I was finished, so I deleted the post and started typing my response to your second message. Thank you for sending it.
