Math Podcasts. Below is a (not complete) list of podcasts and radio shows with downloadables that I have heard over the years that have some connection to math.

Math Podcasts

I have arranged them first by podcasts that are specifically that relate to math. I know that there are more that I haven't listed. That is because I will only list things here that I have actually listened to. If you have any that you have heard that I have missed, please contact me at .This podcast from @MakeMathMoments is the work of @MathletePearce and @MrOrr_Geek where they take their three part framework and unpack it over several episodes.

The focus here is one what makes good teaching and how do we do it in a way that ideas stick with kids. Desmos Collections - Master.

Math Review

Order of Operations. Launch Humans use verbs like "throw", "run", "build" and "jump" to describe operations on nouns like "ball", "puppy", and "blocks".

Order of Operations

Mathematics has "operations" , like addition and subtraction. Just as you can "throw a ball", a person can also "add four and five".

Over 400 Ivy League classes are now free online. Kids aren't the only ones who can take online classes during our coronavirus-riddled time.

Over 400 Ivy League classes are now free online

Ivy League schools in the U.S. are offering 450 free courses for any adults who have spare time while trapped at home. And according to some of the reviews, these classes are for real. Expect to spend a good amount of hours per week watching lecture videos, completing assignments, and doing quizzes. So if you're interested in bettering yourself while social distancing, check out the plethora of subjects and courses offered below.

Computer Science Computer science is where one can learn how to understand computers and computational systems beyond 'it's a machine with the internet on it.' Computer science also encompasses subjects such as cyber security, artificial intelligence, robotics, and solving human-computer interaction. Data Science With computers comes the need to analyze the data. Programming Humanities. Free educational materials for teachers and families.

Ancient Science: Mysterious Babylonian Tablet Could Hold Mathematical Secrets For Today's Researchers. An ancient Babylonian tablet whose purpose has been a longstanding mystery reveals that the ancient Mesopotamian civilization beat the Greeks to the discovery of trigonometry by more than 1,000 years, researchers say—and their methodology might even hold lessons for modern-day mathematicians.

Ancient Science: Mysterious Babylonian Tablet Could Hold Mathematical Secrets For Today's Researchers

The tablet, Plimpton 322, was discovered in the early 1900s in present-day Iraq, according to, and researchers have puzzled over its function ever since. It displays four columns and 15 rows of numbers in the contemporary cuneiform script composed in a base 60, or sexagesimal, system. Dr. Daniel Mansfield, of the School of Mathematics and Statistics in the University of New South Wales (UNSW) Faculty of Science, Sydney, says his research has unearthed the tablet's true meaning. His paper, co-authored with UNSW Associate Professor Norman Wildberger, was published in Historia Mathematica. "It's rare that the ancient world teaches us something new," he said. Dr. Quadratic Method: Detailed Explanation. Alternative Method of Solving Quadratic Equations If you find and with sum and product , then , and they are all the rootsTwo numbers sum to when they are Their product is when Square root always gives valid Thus work as and , and are all the roots Known hundreds of years ago (Viète)Known thousands of years ago (Babylonians, Greeks) The individual steps of this method had been separately discovered by ancient mathematicians.

Quadratic Method: Detailed Explanation

The combination of these steps is something that anyone could have come up with, but after releasing this webpage to the wild, the only previous reference that surfaced, of a similar coherent method for solving quadratic equations, was a nice article by mathematics teacher John Savage, published in The Mathematics Teacher in 1989. Explanation of Quadratic Method, by Example The presentation below is based on the approach in my originally posted article, but goes further. Russ Herman - Open Source Mathematics. Open Source Software for Mathematics The high cost of standard mathematical packages is often a hardship for students and faculty (especially in third world countries).

As a result, more people are joining the open source movement and are seeking ways to circumvent cost, storage and ownership. We review a diverse number of open source software in the ICTCM 2008 talk and accompanying paper. Everyday Open Source Applications. Dlippman.imathas.

The canons of page construction are a set of principles in the field of book design used to describe the ways that page proportions, margins and type areas (print spaces) of books are constructed. The notion of canons, or laws of form, of book page construction was popularized by Jan Tschichold in the mid to late twentieth century, based on the work of J. A. van de Graaf, Raúl M. Rosarivo, Hans Kayser, and others.[1] Tschichold wrote, “Though largely forgotten today, methods and rules upon which it is impossible to improve have been developed for centuries.

To produce perfect books these rules have to be brought to life and applied.”[2] Kayser's 1946 Ein harmonikaler Teilungskanon[3] had earlier used the term canon in this context. Typographers and book designers apply these principles to this day, with variations related to the availability of standardized paper sizes, and the diverse types of commercially printed books.[4] Van de Graaf canon[edit]
