Behold one of the mightiest tools in mathematics: the camel principle.
I am dead serious. Deep down, this tiny rule is the cog in many methods. Ones that you use every day.
Here is what it is, how it works, and why it is essential.
📢 Onderwijs en onderzoek zijn cruciaal om de grote vraagstukken van onze tijd aan te pakken! Toch bezuinigt het kabinet-Schoof €1 miljard op hoger onderwijs en wetenschap. Wij komen in actie tegen deze bezuinigingen! Teken jij ook de petitie? https://t.co/YuY0KWRDwP
Today is #ShowYourStripes, when we encourage people to start conversations about climate change using simple 'warming stripes' data visualisations.
The world is warming mainly because of burning fossil fuels. The consequences are becoming more visible. It's time to take action.
Relax and watch two black holes merge. Inspired by the first direct detection of gravitational waves in 2015, this simulation plays in slow motion but would take about one third of a second if run in real time. Set on a cosmic stage, the black holes are posed in front of stars, gas, and dust. Their extreme gravity lenses the light from behind them into Einstein rings as they spiral closer and finally merge into one. The otherwise invisible gravitational waves generated as the massive objects rapidly coalesce cause the visible image to ripple and slosh both inside and outside the Einstein rings even after the black holes have merged. Dubbed GW150914, the gravitational waves detected by LIGO are consistent with the merger of 36 and 31 solar mass black holes at a distance of 1.3 billion light-years. The final, single black hole has 63 times the mass of the Sun, with the remaining 3 solar masses converted into energy radiated in gravitational waves.
