No...

A deep dive into Daniel Klein's The Spirit of Smithian Laws, reframing Adam Smith as a subtle moral philosopher rather than a mere economist. We trace the impartial spectator (Godjoy), the organon of sympathy, and Klein's spiral of non-foundationalism—how virtue arises in dialogue, relationship, and evolving understanding. We also situate Smith within the late-18th/early-19th-century shi...

A quick dive into A000310, the iterated exponential coefficients. We explore how the numbers grow rapidly (1, 4, 26, 234, 2696, …) and how their exponential generating function—a nested-log expression that mirrors the iterated exponentials—captures the whole sequence. We touch on the historical roots (Jay Ginsberg’s work from 1945) and Sloan’s authoritative treatment in the Handbook (1973) and Enc...

We dive into A000308, defined by a(n) = a(n-1) · a(n-2) · a(n-3) with starting values 1, 2, 3. The growth is astonishingly fast: 1, 2, 3, 6, 36, 648, 139,968, …, a true example of hyper-exponential behavior from a simple triple-product rule. With non-negative initials the sequence stays positive and climbs without bound; zeros or negatives would alter the behavior dramatically. The OEIS entry also...

A clear, practical tour of ancient Stoicism—from its logical foundations and cosmic view to the four cardinal virtues and the idea of indifferents.

In this episode we unpack A000309, the sequence 1, 1, 4, 24, 176, 1456 that counts rooted planar bridgeless cubic maps with two gen nodes. We’ll also see how the same numbers count rooted planar, non-separable triangulations with 3n edges (and with 2n triangles), and for description trees of type 2-man-2 with n edges. We’ll explore the surprising connections to Tamari lattices and lambda calculus,...

From the early internet’s near-collapse to modern TCP’s smart back-off, this episode unpacks how networks avoid congestion. We explain the difference between congestion control and flow control, how feedback and pricing guide traffic, and why UDP complicates things. Join us for a clear, accessible tour of the algorithms, the iconic slow-start, and the engineering that keeps streaming, calls, and p...

We explore A000307, the count of four-level labeled rooted trees with n leaves. Despite the OEIS tag 'easy', the numbers explode quickly, and the mystery is why this structure is considered easy in theory. We explain what 'easy' means in OEIS terms, how the nested generating function exp(exp(exp(exp(x)))-1) encodes the four-level construction, and present the alternative Stirli...
