Between the folds [videodisc] : a film about finding inspiration in unexpected places by Vanessa GouldOrigami may seem an unlikely medium for understanding and explaining the world. But around the globe, several fine artists and theoretical scientists are abandoning more conventional career paths to forge lives as modern-day paper folders. Through origami, these offbeat and provocative minds are reshaping ideas of creativity and revealing the relationship between art and science. This film chronicles 10 of their stories: three of the world's foremost origami artists, less conventional artists, abstract artists, advanced mathematicians and a remarkable scientist who received a MacArthur Genius Award for his computational origami research. While debates ebb and flow on issues of folding technique, symbolism and purpose, this film shows how closely art and science are intertwined. The medium of paper folding--a simple blank, uncut square--emerges as a metaphor for the creative potential of transformation in all of us.

The Birthday Paradox ExperimentHow many people do you need to gather in order to find two individuals with the same birthday? Most people who asked this question tend to answer with a number that is much too high. The phenomenon is known as the "birthday paradox." Russell Goldenberg of The Pudding has created this interactive experiment designed to help visitors understand the math behind the birthday paradox. In this experiment, visitors are invited to share their birthday month and date. Next, they have the opportunity to see how previous visitors answered the question. In doing so, visitors can see the "birthday paradox" in action. As visitors view how an increasing number of participants answered the question, they will view an accompanying graph that demonstrates the law of large numbers. Visitors who enjoy this interactive will want to check out other projects included in The Pudding's Essays About Explainers.
Byrne's EuclidEuclid's Elements has been the standard in geometry textbooks for millennia, with hundreds of editions published since the ancient Greek mathematician created it at around the year 300 BCE. One edition was particularly noteworthy for its technological innovation: Oliver Byrne's 1847 edition, which stood out for its cutting-edge use of multiple colors in its diagrams rather than traditionally written labels, lending it an artistic quality as well as making the ideas easier to understand. Now, Byrne's Euclid has entered the digital era thanks to Chicago-based web designer and artist Nicholas Rougeux, who recreated Byrne's edition as an interactive website. Launched in December 2018, this project faithfully reproduces Byrne's version of Elements in its entirety, including its color scheme, graphics, and typography. Here, visitors can view all six books of Byrne's edition as well as its introduction and glossary of symbols, which Rougeux has enhanced with clickable shapes to help illustrate the ideas being discussed as well as links to cross-references within the text. Those interested in the background of this project should visit its about page, where they will find a short summary and a link to a lengthy blog post explaining how Rougeux created this site.
Celebratio MathematicaMath educators and aficionados may be interested in Celebratio Mathematica, an open-access digital publication that "celebrates mathematics and related fields, and their people." Visitors to this project will find extensive information on the lives and work of nearly thirty noteworthy mathematicians (as of this write-up), with each person's entry organized into an "enhanced guide to [their] collected works." These digital volumes include such figures as David Blackwell, "an eminent statistician who specialized in probability and game theory," and Emmy Noether, a pioneer in abstract algebra and the namesake of several influential concepts. Each volume contains a collection of biographical narratives (sometimes in the mathematician's own words), a bibliography of their published work, commentaries by other mathematicians on the significance of their work, information on their graduate students, and more. For anyone curious about the careers of prominent twentieth-century mathematicians, this project is a valuable resource. Celebratio Mathematica was conceived by Robion C. Kirby and James W. Pitman, both professors of mathematics at the University of California, Berkeley and published by MSP (Mathematical Sciences Publishers), a nonprofit scholarly publisher.
Estimation 180As mathematics teacher and learning coach Andrew Stadel explains, problems can help mathematicians develop their number sense and problem solving skills. Stadel has created Estimation 180, a compilation of classroom activities and lesson plans that center on the skill of estimation. The name of the site comes from the 180 short estimation problems (one for each day of the school year) that are at the center of this project. Each of these problems include a picture accompanied by an estimation problem (e.g. How many sheets of paper are in this box?). Students or classrooms are invited to fill out a Google Form with their estimate and reasoning and explore other responses (along with the correct answer.) These problems offer a useful series of anticipatory sets for elementary school classrooms. In addition, mathematics teachers may want to check out the Clothesline Activities and the Lessons sections for some more ready-to-use classroom materials.

How Much Does Kid Cudi Hum?One thing is clear: Grammy award-winning artist Scott Ramon Seguro Mescudi, known by his stage name Kid Cudi, loves to hum. In proving this point, Connor Rothschild's project flexes coding, data analysis, and statistics skills. Hip-hop fans will appreciate the project for its discography analysis, but even those less familiar with Kid Cudi's music can benefit from the methodology and apply it to a passion project of choice. In other words, here is proof that calculations can be creative, too. At the link above, viewers can explore findings that measure concentrations of humming, show the evolution of Cudi's humming over time, and dive into statistics by track and album. Among other options, users will discover what proportion of Kid Cudi's songs are made up of hums (notably, only 53 of the 226 of Cudi's songs on Genius omitted humming entirely). The project also reveals Cudi's preference for starting and ending his tracks with humming. Notes on Rothschild's research and coding process are available at the conclusion of the piece.

Thankfully, she also writes an excellent, readable blog, where the rest of us can peruse her thoughts on mathematics, gender, the academy, and whatever else happens to be on her unusually brilliant mind on any given day. Recent posts have taken on the dirty politics inherent to website comments sections, engaged a debate over social science terminology as applied to the examination of gender in the math community, and thought through how the internet and mass communications might impact the field of academic mathematics. While some of these articles concern the complexities of high level math, many of them focus on issues that women in academia face, regardless of their area of specialty. Readers interested in a feminist take on the academy will find much to appreciate on this erudite blog by a well-respected mathematician.

Instructors can participate in live webinars each Tuesday evening at 9:00 PM EST; alternatively, anyone may view recordings of all past webinars on this website. To learn about upcoming webinars, one can check out the website's calendar. The Global Math Department also publishes a weekly online newsletter that highlights articles related to math instruction and features digital tools that can be used in the classroom. In addition to curriculum and instruction ideas, there are also many tips about blogging and using Twitter on this website.
Kids Math TalkFounded by Desiree Harrison, a math educator and National Council of Teachers of Mathematics Board member, Kids Math Talk is part podcast, part blog, and all about math. The site serves as a resource for educators and caregivers who are searching for ways to make math accessible, active, and fun. Marvel over mathematicians with the podcast's recent focus on uplifting voices from the math community, or explore the archive for plenty of practical tips to "create a positive narrative about math and the role that it plays in our lives." The podcast element of the platform launched in June of 2020, so it unsurprisingly focuses on making math education work in online environments. Episodes are usually less than 45 minutes, and most are accompanied by a transcript of the content. Listeners will also find the show on Apple Podcasts and Spotify, though a benefit of following the link above is the opportunity to explore the other site features; for example, readers will find a collection of math Resources (some for free, others for a fee) and a Blog. Readers can also keep up with the podcast, and Harrison's work generally, by following along on Twitter and Instagram, @Kidsmathtalk.
Math Ed PodcastDesigned for mathematics educators, the Math Ed Podcast features conversations with experts across the globe about a wide variety of issues relating to mathematics instruction and the latest research in the field. This podcast was founded in 2012 by Samuel Otten, assistant professor of mathematics education at the University of Missouri. One recent episode features a conversation with Mandy Jensen and Dawn Berk, both of the University of Delaware School of Education, discussing their recent publication that examines the impact of an elementary mathematics education program on the instructional practices of six first-year teachers (all graduates of the same program). In another episode, UW-Madison professor emerita Elizabeth Fennema describes her research about gender and mathematics.
Math ValuesFrom the Mathematical Association of America (MAA) comes Math Values, a new blog launched in 2018 that "explores the diverse voices of mathematics and discusses topics related to and affected by mathematics." Here, readers will find informative articles written by professional mathematicians, math educators, and even math students. Examples of article topics include a recently implemented California law mandating a change in how community college students are placed in math courses, interviews with principal investigators of math education research projects that have received grants from the National Science Foundation, and a student's response to a paper critiquing the International Mathematical Olympiad. Math Values is organized into four thematic categories (Inclusivity, Community, Communication, and Teaching & Learning) that can be reached via a menu at the top, where readers will also find the site's search bar. Readers of past MAA blogs may also find new articles from some familiar columns here, such as Devlin's Angle and Launchings, written respectively by Keith Devlin and David Bressoud. Math Values will likely be of particular interest to STEM educators and administrators.
MathologerThe holidays may be a popular time for pie, but every day could use a little pi (the mathematical constant, of course). Mathologer, a YouTube channel operated by Monash University (Melbourne, Australia) math professor Burkard Polster, brings viewers all that and more. Polster's friend and fellow math professor Marty Ross collaborates on videos behind the scenes. Together, the duo created an informative and well-received platform that has garnered a significant following since launching in 2015. Most videos have more than 100,000 views, and some have more than one million. These videos tackle fascinating formulas and theorems and walk users through examples to test knowledge along the way. Though the content is often complex, plenty of humor is mixed in to keep viewers engaged. Plus, videos range in length, and some of the shorter snippets may be a welcomed tool for math educators. Readers in the holiday spirit may enjoy the December 24, 2019 video on "Fermat's Christmas theorem." New videos are released semi-regularly, so check back often for additional content.
My Favorite TheoremThose curious about the connection between Falting's theorem and New York City bagels (see Episode 53) may enjoy My Favorite Theorem. Hosted by math enthusiasts Keith Knudson and Evelyn Lamb, the podcast focuses on "sharing our guests' favorite mathematical results." While the show partly takes a traditional approach, asking guests to describe their favorite theorem, the podcast also mixes it up. Noting that "the best things in life come in pairs," the hosts "find out what our guest thinks pairs best with their theorem." For example, in Episode 54, Professor Steve Strogatz discusses connections he sees between Cubism paintings and Cauchy's theorem. Discover other unique pairs by listening to the more than 50 episodes released since 2017. These episodes, each around 30 minutes in length, can be found at the link above or on Spotify, Apple Podcasts, and other popular streaming platforms. Readers looking for additional content can follow My Favorite Theorem on Twitter (@myfavethm) or browse the rest of Knudson's website (including a blog and resources from his presentations). Readers can find some of Lamb's math writing by reading her Roots of Unity blog in Scientific American or checking out her website at www.evelynjlamb.com.
Quanta Magazine: Abstractions BlogQuanta Magazine, the online publication dedicated to mathematics, theoretical physics, computer science, and life science, is home to Abstractions, a blog that explores promising ideas in science and mathematics. For example, one recent post describes new theories about Type 1a supernovae and why they explode. Another recent entry commemorates Marjorie Rice, who died in July 2016 at the age of 94. Rice, who had only taken one mathematics class in high school, discovered four tessellating pentagons that "'tile' the plane, locking together with copies of themselves in endless patterns." Another recent post explores the Human Cell Atlas project and what this atlas may contribute to research about diseases and human behavior. As with the rest of the magazine, Abstractions is a great resource for those interested in keeping up with new theories, conversations, and debates in the mathematics and science communities.
Sara VanDer WerfSara VanDerWerf is a high school mathematics teacher who also serves as a consultant to other mathematics educators. Mathematics tutors and teachers will find a number of resources and ideas that may be of interest in her blog. These resources include classroom activities, lesson plan ideas, teaching reflections, and links to relevant outside resources. In one recent post, VanDerWerf discusses five things elementary school teachers can do to prepare students for secondary mathematics classes. VanDerWerf developed this list with Laura Wagenman, an elementary school math educator. In another recent post, VanDerWerf shares photographs of her classroom space (which includes a "calculator museum"), accompanied by explanations of how she sets up her classroom. In another post, she describes a "stand and talk," which is a variation of the think-pair-share activity designed to increase student engagement.
