Simulating and Visualising the Central Limit Theorem

Simulating and Visualising the Central Limit Theorem Categories: Statistics R 34 minutes read I completed a Computer Science degree at uni, and bundled a lot of maths subjects in as electives: partial differential equations, vector calculus, discrete maths, linear algebra. For some reason however I always avoided statistics subjects. Maybe there’s a story to be told about a young person finding uncertainty uncomfortable, because twenty years later I find statistics, particularly the Bayesia

USDA Weaponizes Adam Driver and Scarlett Johansson’s ‘Marriage Story’ Fight to Scare Wolves

Noah Baumbach wanted to challenge audiences with Marriage Story, making them sit in the discomfort and tension of a relationship falling apart. He probably didn’t know that his audience was going to be wolves, though. According to a report from the Wall Street Journal, the famous fight scene between Adam Driver and Scarlett Johansson from Baumbach’s award-winning drama is just one tool the United States Department of Agriculture has started to use in an effort to scare the growing wolf (and hung

Structural-Demographic Theory

The causes of revolutions and major rebellions are in many ways similar to processes that cause earthquakes (Goldstone 1991: 35). In both revolutions and earthquakes it is useful to distinguish the structural conditions (pressures, which build up slowly) from triggers (sudden releasing events, which immediately precede a social or geological eruption). Specific triggers of political upheavals, such as self-immolation of a fruit vendor, which triggered the Arabic Spring in Tunisia, are very hard

‘I witnessed war crimes’ in Gaza – former worker at GHF aid site [video]

A retired US special forces officer has revealed to the BBC why he resigned from his work with US- and Israel-backed Gaza Humanitarian Foundation (GHF) aid distribution centres. "I witnessed the Israeli Defense Forces shooting at the crowds of Palestinians," Anthony Aguilar told the BBC. He added that in his entire career he has never witnessed such a level of "brutality and use of indiscriminate and unnecessary force against a civilian population, an unarmed, starving population".

Is It Time to Stop Protecting the Grizzly Bear?

This story originally appeared on Vox and is part of the Climate Desk collaboration. In the early 1900s, long before smartphones and selfie sticks, tourists flocked to Yellowstone National Park—not for the geysers or scenery, but for a grotesque show: a nightly spectacle of grizzly bears raiding cafeteria scraps from open-pit landfills like desperate, starving pirates. The bears were in dangerous proximity to humans: Hungry bears tore at open car windows. Tourists posed a little too close with

Aging-related inflammation is not universal across human populations

Inflammation, long considered a hallmark of aging, may not be a universal human experience, according to a new study from Columbia University Mailman School of Public Health. The research suggests that "inflammaging"—chronic, low-grade inflammation associated with aging—appears to be a byproduct of industrialized lifestyles and varies significantly across global populations. The findings are published in Nature Aging. Researchers analyzed data from four populations: two industrialized groups—th

America’s incarceration rate is in decline

For more than 40 years, the United States—a nation that putatively cherishes freedom—has had one of the largest prison systems in the world. Mass incarceration has been so persistent and pervasive that reform groups dedicated to reducing the prison population by half have often been derided as made up of fantasists. But the next decade could see this goal met and exceeded: After peaking at just more than 1.6 million Americans in 2009, the prison population was just more than 1.2 million at the e

Spatializing 6k years of global urbanization from 3700 BC to AD 2000

Transcription Chandler’s book includes population data from 2250 BC to AD 1975 in various charts and tables. The book contains 656 9×5.5 inch pages and is divided into multiple sections, including Sources and Methods, Continental Tables and Maps (highlighting locations of major cities as illustrated in Fig. 4), Data Sheets for Ancient Cities (the main tables of the book shown in Fig. 1), Tables of the World’s Largest Cities, and Whereabouts of Unfamiliar Cities.
