Wishing all my American chums a very happy thanksgiving with this absolutely awesome image of the ❤️👾 Pacman Nebula! It was captured by the fab Gilmerton Primary School P7s on their recent residential visit to Benmore, which is part of our Scottish Youth Telescope Network. #SYTN 🔭🧪
A star-studded image. in the middle is a red puff in the shape of a heart (or Pacman depending on your view). Text reads Seestar S50, NGC 281, 42mins

Theorem of the Day (November 22, 2025) : Bertrand’s Ballot Theorem
Source : Theorem of the Day / Robin Whitty
pdf : buff.ly/QKVqBpU
notes : buff.ly/W9V4Rc3

#mathematics #maths #math #theorem
Comprehensive presentation of the "Theorem of the Day", starting with a statement of this theorem. Bertrand’s Ballot Theorem : In an election where m people vote for candidate a and n for candidate b, suppose that m > kn, for some positive integer k. Then the probability that candidate a has always, from the first vote onwards, more than k times as many votes as candidate b is given by (m − kn)/(m + n).

We had @carnegiescience.bsky.social 's Bob Hazen on about the steps building to this precisely because the chemical traces of early life seemed so promising.

The image I chose for the start is a detail of the "Glasses Apostle" painting in the altarpiece of the church of Bad Wildungen, Germany. Painted by Conrad von Soest in 1403, the painting is considered to be among the oldest depictions of eyeglasses north of the Alps. What a cool reader, right?

This is a "reindeer cyclone", a defensive behavior that has been observed in herds of reindeer, even in captivity.

The fawns and older animals are at the center, the strongest animal in the outer lanes.

The point is to confuse the brains of predators accustomed to stalking a single outlier.

#CNRSnews 📰 The chemical revolution of the early 20th century was a golden age for painters with the rising number of pigments available. Scientists are scrutinising Robert Delaunay’s colours, especially his purples, in an effort to conserve his works 🎨🖌️

Seeing life in purple
The early 20th-century artist Robert Delaunay began painting at a pivotal moment in art history, namely during the chemical industry revolution, when the number of pigments available on the market increased. Today scientists are trying to solve the mystery of the painter’s colours, his purples in particular. One of the objectives of this research is to generate knowledge essential to conserving the works.
