Music Theory, Language Transfer, and the Thinking Method
I’ve wanted to learn music theory for a number of years, but have never found a source that’s both engaging and educating. That is, until now, thanks to Language Transfer’s music theory course. For a while now, whenever I’ve read an article or post about language learning, someone in the comments invariably praises Language Transfer…

The Wug Test and Language Development in Children
The Wug Test is a foundational study in how language develops in children. It’s also a bit cute: Developed by Jean Berko Gleason in the 1950s, it’s been said that the only thing with a greater impact on the field of child language research was the innovation of the tape recorder. Gleason’s major finding was…

Two Palms to a Shaftment: English, Imperial, and Customary US Units
English units were the measurement standards used across the British Empire until 1826; it’s the system that immediately preceded and (independently) developed into today’s imperial units and US customary units. I never really thought about why the UK and US diverged slightly, but (obviously, in retrospect) the simple reason that imperial and US customary units…

Longevity FAQ and Longevity 101: Your Beginner’s Guides
I find the concept of longevity and longevity research fascinating, from both a scientific and philosophical perspective: it’s cool to read about how researchers have effectively reversed the ageing of some mice, and I find it endlessly curious how large swathes of society want to ‘solve’ ageing (or, maybe more accurately, the other things that…

Studying and Learning: What Works, What Doesn’t
Self-testing and spaced repetition are the “two clear winners” in how to study and learn better. That’s from an informal meta study conducted by six professors (from fields such as psychology, educational psychology, and neuroscience) when they reviewed over 700 scientific articles to identify the ten most common learning techniques and which are the most…

International, Multilingual Eye-test Chart, 1907
At the turn of the twentieth century, in San Francisco, German optometrist George Mayerle created and published the “international” eye-test chart: “an artifact of an immigrant nationâproduced by a German optician in a polyglot city where West met East (and which was then undergoing massive rebuilding after the 1906 earthquake)âand of a globalizing economy”. Running…

Perceptions of Probability and Numbers
Back in 2011 I wrote about “words of estimative probability“; the quantitative ranges we apply to ambiguous words and phrases, based on Sherman Kent’s research for the CIA in the 1960s. In 2015, Reddit user zonination duplicated the study using /r/samplesize. His resulting post in /r/dataisbeautiful made the longlist for the 2015 Kantar Information is…

Big History: A History Course Covering 13.8 Billion Years
Big History is an academic course covering “our complete 13.8 billion years of shared history”. From the Big Bang to modern-day society, the course is structured around eight “threshold” moments of increasing complexity, synthesising aspects of cosmology, physics, chemistry, geology, and anthropology to weave a unified story of history so far. The eight thresholds: I…

Sagan’s Cosmos on the Scientific Method and Uncomfortable Ideas
I’m currently watching Carl Sagan’s excellent Cosmos: A Personal Voyage. I feel compelled to post the following quote from episode four, Heaven and Hell, as it stood out for its elegant argument for the strength of scientific ideas and for not rejecting uncomfortable (if incorrect) ideas: There are many hypotheses in science which are wrong. That’s all…

Size and Complexity: Why Animals Are the Way They Are
From bone strength and oxygen absorption in larger animals, to the perils of surface tension and poor eye design in smaller ones: just some ideas to consider when studying comparative anatomy and why animals are the way they are. A perfect take on the topic is J. B. S. Haldane‘s 1928 On Being the Right Size. In this…
