Jean Golding: a tale of illness, adventure and statistics
Ada Lovelace Day, a day to celebrate female role models in science, technology, engineering and maths (the STEM subjects). Last year, Ada LovelaceDay produced an ebook, for which I wrote a chapter about Jean Golding, the woman who set up Children of the 90s, the dataset I use for my PhD. Here’s an extract.
Supersized dinosaurs divided up their dinner
The giant sauropod dinosaurs like Diplodocus and Apatosaurus are familiar thanks to their huge sizes and unique body shapes of a long neck and tail with a tiny head perched on top. Among their ranks were the largest terrestrial animals of all time, and yet an enduring mystery remains – how did so many animals of this size get to be so big?
