Researchers from Brazil's Universidade Estadual de Campinas used a computer simulation to confirm paleontologist Stephen J. Gould's prediction that it is evolutionarily advantageous for cicadas to emerge at intervals lasting a prime number of years.
Does The Apple Logo Really Adhere To The Golden Ratio?: David Cole:
Okay, the original logo was not the mathematical masterpiece (mathterpiece?) that we know today, but maybe Landor & Associates introduced the golden ratio when they touched it up. I couldn’t find any information online about their design process, but in looking at examples of the Apple logo after L&A worked on it in the early ’80s, you can see it was much closer to the logo we know today:
I have posted a revision of the article Conceptual and Computational on abstractmath.org. It is the result of my first adventure in revising abstractmath.org in accordance with the ideas in my recent Gyre&Gimble post Writing math for the web. One part of the new article incorporates some of the ideas of my post The power [...]
Kurt Friedrich Gödel (1906 - 1978) was an Austrian-American mathematician and logician best known for proving the Gödel's incompleteness theorems. He showed that within any axiomatic mathematical system there are propositions that can not be (dis)proved using the axioms of the system. He is generally considered as one of the greatest logician of all time.IPA:[ˈkʊʁt ˈfriːdrɪç ˈɡøːdəl]Listen:Player 1: Player 2:
I'm going to be writing a couple of posts looking back at a class I've taught that's just coming to an end (at the time of writing this I've got one more group presentation to see).The course teaches SAS and R in parallel on our MSc course (if it's of interest all the teaching materials are here).I'll be blogging about this class as I taught it a bit differently to the usual "Students Listen - Teachers Lecture" style. I'll get back to that more in future posts (although a lot of what I've done [â€¦]
