Witch Trials across Europe

Even though the stereotype of the Spanish Inquisition being religious fanaticals, they did not prosecute witchcraft because they correctly considered it mere superstition.

Driving all roads in the UK from London at once

I've further improved my global traffic / congestion / road quality formula. Times start from the OSM speed limits, then every road gets scaled by three things:

- traffic, guessed from population density: 1 + 1.09·d/(d+5000), where d is people per km². Basically nothing in the countryside, about 2x in a dense city centre

- bendiness, on fast roads only: 1.45 + 3.16·B/(B+406), where B is degrees of turning per km. Turns out nobody does 60 on a twisty B-road

- junctions: 0.64·(1 + 0.84·J/(J+5.35)), where J is side roads per km

I checked it against Mapbox's typical Tuesday lunchtime traffic on ~2,500 routes in 33 countries. It's usually within about 10%. Still a bit optimistic around London though.

DNA-based ancestry across Mexico’s 32 states: Mexican Biobank sample (2023)

Thumbnail

188 Upvotes

I redid the Mexican ancestry map that gets shared online that uses some old study. I did this one the using DNA-based estimates from the Mexican Biobank study published in Nature in 2023. The study genotyped 6,057 people from 898 locations across all 32 states.

The ancestry percentages were inferred from genetic data, not racial or ethnic self-identification. I reviewed other genetic studies for context, but all the plotted state values come from the same study. I made the map and charts in Python.

One important limitation: these describe the study sample, not population-weighted averages for each state, so rural localities and Indigenous-language speakers were deliberately oversampled.

Closest living people: Copts and Yemenis. Scandinavians (0.27) and Indians (0.36) before Subsaharan Africans (Dinka 0.64, Yoruba 0.68).

Egyptian Arabs from Cairo: 0.090. Behind Bedouins from Jordan, Tunisia, and Libya. Coptic Christians (0.056) are the last genetic link to pharaonic Egypt.

Genetic similarity does not necessarily mean direct ancestry.

The 1962 election saw the Progressive Conservative government of John Diefanbaker reduced from the largest majority government in Canadian history to a weak minority government which would fall not even a year later. If you have any questions feel free to ask, I would be more than happy to explain.
