Miscellaneous
- Latin America holds 8% of the world’s population but 38% of its criminal killing. Around 140,000 people were killed in 2017 only, more than have been lost in wars around the world in almost all of the years of the 21st century. (The Economist, 7/4/2018)
Weird
- The aerospace division of PPG imitate dark-purple skin of aubergines in aircraft painting. Instead of absorbing infra-red radiation, an aubergine’s skin permits such wavelengths to pass through. They are then reflected back out again by the vegetable’s white interior flesh. That way, an aubergine in a sunny field remains cool. By dispersing specially engineered pigments in a dark-coloured surface layer over the top of a reflective white underlayer, PPG was able to achieve the same thing for aircraft paint.
