What Would Math and Physics Be Like in a 1 Dimensional World You're a point mass and you live on the x axis. That's your entire world. It's "Lineland". What's your life like? First, as regards moving, you only have two directions, forward and backwards. And if you meet another point mass you cannot pass. So you can only know two other masses. You have just two friends maximum! And this means you have no reason to count objects beyond two. So you might be slow in developing the concept of
A Mysterious Relationship Between the 5 Most Famous Numbers in Mathematics Imagine calculating this.. (1+(1/n))^n where n is an integer n=1,2,3,.. You would notice something interesting. As n gets bigger and bigger the value seems to approach a specific number. It does, as n approaches infinity the value of this expression approaches the number e. It's a famous mathematical constant.. e=2.718281828459045.. So mathematician say that.. e=limit as n goes to infinity of (1+(1/n))^n The number e
What's the Number e? Imagine calculating this.. (1+(1/n))^n where n is an integer n=1,2,3,.. You would notice something interesting. As n gets bigger and bigger the value seems to approach a specific number. It does, as n approaches infinity the value of this expression approaches the number e. It's a famous mathematical constant.. e=2.718281828459045.. So mathematician say that.. e=limit as n goes to infinity of (1+(1/n))^n The number e shows up in many areas of math and physics and is
This post is intended as a footnote to one that I wrote a couple of years ago about the meaning of “implies” in mathematics, which was part of a series of posts designed as an introduction to certain aspects of university mathematics. If you are reasonably comfortable with the kind of basic logic needed in […]
In 2010, a controversial article published in Nature violently criticized the last 40 years of developments in evolutionary biology, triggering an ongoing war within the scientific community. This article explains the essence of the controversy!
I was proud to be a part of Math for America’s second annual MT^2 event , Master Teachers on Teaching. MT^2 invites MfA teachers from around New York City to propose short talks related to the conference theme. This year’s theme was Change, and the seven teachers selected to present offered many different and interesting interpretations of that theme, […]
The math bibliophile in me is always excited when our local public library holds a used book sale... and today my lucky find was "Mathematics: People Problems Results," a 3-volume anthology set from 1984, edited by Douglas Campbell and John Higgins. It looks to be a scrumptious set of ~90 rich essays (including some classics) from a great panoply of superb (and famous) writers/mathematicians. As I've said before, math is so timeless that even a 30-year-old book-set like this can contain […]
Mathematicians Wrote a Paper on How the Zombie Apocalypse Won’t Kill Us All, Made Us Grateful for Math: Dan Van Winkle:
Building on the work of another paper about how a zombie apocalypse would go down, because that’s a thing mathematicians apparently work on, Caitlyn Witkowski of Bryant University and Brian Blais of Brown University have written a paper on their mathematical findings that a zombie apocalypse wouldn’t wipe us all out, so that’s comforting.

Teachers concerned about declining math scores: Caroline Alphonso:
Canada’s fall from the top 10 in its international math standing, revealed this week by the OECD’s Programme for International Student Assessment (PISA), has been partly attributed to insufficient instruction in the fundamentals of math, such as multiplication tables. Across the country, some of the people most concerned about declining math scores are math teachers, who understand that effective instruction in numbers,
500 Lightstick-Toting Maths Enthusiasts 'Pythagorized' NYC's Iconic Flatiron Building In Epic Fashion: Andy Kiersz:
As part of their first anniversary celebrations, the Museum of Mathematics (MoMath) and about 500 maths enthusiasts of all ages proved that New York’s iconic Flatiron building is approximately in the shape of a very special type of right triangle.
