Absolutely gutted by the election results in Saxony-Anhalt in Germany. I know people directly affected by them, and they are now afraid of the direction their federal state is taking. And of course far-right figures like Musk are never far away. www.theguardian.com/world/2026/s...

A small group of transphobes are protesting on High St, Cardiff city centre. An impromptu gathering of trans folks an allies have formed an already bigger counter demo, supported by local businesses handing out rainbow drops and blasting Lady Gaga! Anyone in the area should join us!

Happy (topological) Valentines Day!

Two strips of paper glued together to form two Möbius strips.

The two Möbius strips glued together back to back.

Cut both strips open along the middle circle. The picture shows what this looks like when you cut the first strip open.

If you have chosen the orientations of the Möbius strip correctly, then the result will look like two interlinked paper hearts, which are shown in the picture.
