The generalized Poincare conjecture is an undergraduate-level point-set topology problem for n=1 . The n=2 case was proven by Poincare. The n=3 case was recently proven by Perelman. The n=4 case is the only outstanding case.

Map of Scotland with white areas around the coast highlighted. White areas are around most of the coast, though Orkney looks especially affected.

The prompt for day 12 of the #30DayMapChallenge is a "map from 2125", and this one *almost* fits that description! This shows the areas of Scotland likely to be affected by coastal erosion by 2100 πŸ—ΊοΈ

A line chart plots a dramatic trend in the % of children dying before the age of 5 worldwide. In 1820, the figure is 43%, which stays fairly constant until the beginning of the 1900s and then plummets dramatically to just 3.7% in 2020. A spike to 38.5% in 1918 marks the outbreak of the 'Spanish Flu'

The First Photograph of a Human Being: A Photo Taken by Louis Daguerre in 1838 You’ve likely heard the reason people never smile in very old photographs. Early photography could be an excruciatingly slow process.

World map visually representing the number of inhabitants per doctor. Different regions are filled with numerical values, with higher numbers indicating more inhabitants per doctor. Variations are emphasized through shades or sizes of the numbers. The title reads "NUMBER OF INHABITANTS PER DOCTOR".

Apparently this is a poster which hangs on the wall of doctors surgeries in The Netherlands. Data is from 2007. Hopefully the numbers are better now?

A 3D rendered map of South America, emphasizing the topography. The continent is depicted in a blue hue, with a prominent mountain range running along the western coast rendered in warm colors, transitioning from yellow to orange to red, indicating varying elevations. The rendering gives a textured, blocky appearance to the landmass. The image includes text attributing the map to @cstats1, made in rayshader, with data from NASA SRTM.

Mural celebrating farm workers. At the center, framed like a president on US currency, is a person in work clothes: sweatshirt, baseball hat, sunglasses, scarf across their face. They are protecting themselves from the irritants of their demanding job, not hiding their identity, but it could be anyone behind the work gear.
There are scene of people at work on either side of the central figure. 
This painting is monumental, eight feet high and twenty feet long.
This file focuses on the center of the mural

Where are the Louvre jewels now and can France get them back? Experts warn that whilst the criminals may yet be caught, the gemstones they stole may never be recovered.

It took just 8 minutes for thieves to steal the Napoleonic-era crown jewels from the Louvre. There weren't enough cameras and the ones there were there were facing the wrong way.

Could a 50-year-old maths problem have foiled the heist?

a slide with some scribbly sketches and then a snippet of a finish comics page based on those sketches, with words "I've realized I'm very good at drawing badly - which is key to finding connections and making
discoveries in my own drawings..." and then a snippet of a mini-comic, at top - straight line stretches from point A to B. Immediately below, same dot at A, then becomes a curving, meandering line that winds through the page and ends at a point with rays and a question mark emanating from it. Text reads: "Nothing can do this for you - for that robs you of experience and conflates answers with learning. Rather, it's all the decisions you make along the way, the mistakes, struggles, and surprises! These pathways you create - this is learning.

In my talks this wk, I placed my notion of the importance of drawing badly to find unexpected connections alongside my Ai statement - we need that struggle, to make mistakes in order to be surprised - it’s the decisions along the way that make us who we are and there is no shortcut to getting there…
