A quick Deep Dive into A000346, defined as the Catalan numbers convolved with powers of 4. We explore its clean closed form, generating function, and the multiple combinatorial faces—Dyck paths, symmetric functions, and integer compositions—and what these connections reveal about growth and recurrence structure.

The case of Nicola Sacco and Bartolomeo Vanzetti, two Italian immigrant anarchists executed in 1927 for a 1920 murder and robbery in Massachusetts, remains a landmark example of judicial prejudice. Arrested during the height of the Red Scare, their trial was less about evidence and more about their political beliefs and ethnicity. Judge Webster Thayer exhibited overt bias, and the evidence was deeply conflicting, relying heavily on the fact that the men were armed and gave inconsistent statem...

Nvidia CEO Jensen Huang says the world faces a severe labour shortage – 50 million workers by the end of the decade.The boss of the world’s most valuable company thinks humanoid robots will be needed to fill the gap.But is this prediction based on solid evidence?Tim Harford looks at the calculations behind the claim with Rajiv Gupta, a technology expert at Boston Consulting Group, who is the likely source of the 50 million figure.If you’ve seen a number in the news you think we should look at,

Welcome to the deep dive today. We're getting into something most of us well try pretty hard to avoid, yeah, failure, but we're looking at it differently, not just as you know, something that happens by accident, but maybe as a source of insight, even creativity, exactly. And we've got some really fascinating, almost polar opposite sources to explore this. On one hand, there's the incredibly unique, you could say, eccentric philosophy of the Scottish artist Ivor Cutler, ah, the poet and songw...

Send us a textThis is the sixth of seven episodes where our guests demonstrate various classroom debate routines. In this episode, we see another example of the routine where students have to prepare both sides of an argument ahead of time: a Point-Counterpoint Debate.

A deep dive into the enigmatic Picts—Brittonic-speaking peoples of northern and eastern Scotland—and how their rise, language, and symbols laid the groundwork for the kingdom of Alba. We trace Fortriu’s power, the pivotal battles at Dun Nechtain, the Viking-age upheavals, and Kenneth MacAlpin’s dynastic shift, exploring the gradual Gaelic integration that followed. Along the way, we decode the iconic Pictish stones and consider how Pictish language and identity echo in modern Scottish Gaelic ...

Lucie and Roger discuss the intricacies and applications of crop simulation models in agricultural research. Roger explains the historical development of these models since the 1980s and provides a detailed explanation of how crop simulation models work, such as the DSAT and APSIM systems, which are used extensively in the United States and Australia. The discussion underscores the models' value in complementing traditional field experiments, especially in understanding long-term agricultural

Send us a text What happens when we stop teaching math as a set of steps to memorize and instead create space for students to explore, question, and discover? In this episode, we dig into how shifting our approach to math instruction can transform classrooms—and mindsets. This episode is packed with insights and practical strategies for making math class more engaging, joyful, and effective.

A journey from a physics-inspired partition problem to a concrete lattice-point counting interpretation. We explore A000345, the nonnegative sequence counting partitions into non-integral powers, with roots in a 1951 statistical mechanics paper by Agarwala and Auluck and entries in Sloan’s Handbooks. In 2009, R.J. Mathar gave a concrete reinterpretation: the partition count equals the number of integer solutions to a radical inequality, turning an abstract partition problem into counting latt...

This episode of Room to Grow brings together our 2025 series on the Mathematics Teaching Practices from Principles to Actions, an NCTM publication. After discussing each of the eight practices in isolation over the last several months, this month tackles the ideas and challenges in actually making substantive change to classroom practice. Our hosts share ideas for engaging with others in deeper professional learning, coaching, and peer observations, as well as ideas for individual teach...

Sue Looney, Same but Different: Encouraging Students to Think Flexibly ROUNDING UP: SEASON 4 | EPISODE 2 Sometimes students struggle in math because they fail to make connections. For too many students, every concept feels like its own entity without any connection to the larger network of mathematical ideas.  On the podcast today, we’re talking with Dr. Sue Looney about the powerful same and different routine. We explore the ways that teachers can use this routine to help students identify

In this episode of Math Science History, we journey back to 8th-century England to uncover the story of Alcuin of York, a quiet but powerful force behind the Carolingian Renaissance. From his beginnings in the cathedral school of York to his influential role as Charlemagne’s advisor, Alcuin shaped the future of Western education, preserved ancient texts, and helped revive a culture of learning in a world on the brink of intellectual collapse. Discover how this humble teacher from northern England

A000344 counts a surprising blend of combinatorics and algebra. It arises as the number of lattice paths from (0,0) to (n,n) that touch but never cross the line x - y = 2 (i.e., stay on or below x - y = 2), which is the 5-fold convolution of the Catalan numbers. Equivalently, it tallies standard Young tableaux of shape (n+2, n, 2), and its ordinary generating function is A(z) = z^2 C(z)^5, where C(z) is the Catalan generating function. We’ll sketch the combinatorial picture, connect to the 5-...
