We're a week into teaching term here at Maynooth University and I'm taking a short break from the task of preparing notes and problem sets for the modules  I'm teaching this term.  Yesterday I came across a paper with the title Typed Versus Handwritten Lecture Notes and College Student Achievement: A Meta-Analysis. I always cringe when I see the word "Meta-Analysis", as this is a very problematic statistical approach.

Probabilistic inference in very large universes

Suppose we have two cosmological theories: A, which describes a very large universe in only a tiny part of which low-energy physics turns out like ours; and B in which we have a possibly much smaller universe in which low-energy physics is like ours…
Probabilistic inference in very large universes
Suppose we have two cosmological theories: A, which describes a very large universe in only a tiny part of which low-energy physics turns out like ours; and B in which we have a possibly much smaller universe in which low-energy physics is like ours with a high probability. Can we determine whether A or B is the "better" theory, and if so how?

Captn. Ferrers telling me, among other Court passages, how about a month ago, at a ball at Court, a child was dropped by one of the ladies in dancing, but nobody knew who, it being taken up by somebody in their handkercher.

Cops go to protests itching for violence and will provoke it if doesn't happen.
It wasn’t impossible - the cops where there to incite violence. And Albanese (and everyone else) knew this would happen and he let it.

Assistant police commissioner Peter McKenna: "It was really quite precarious at times for our officers who were significantly outnumbered by the protesters and the people who wanted to act in a violent and offensive manner."

The date of publication for that paper was 8th February 2016, i.e. excactly10 years ago today. Here is the overlay: In those days OJAp was very much an experiment, and we used a protoptype platform which I had paid a developer to set up but it never really progressed beyond a "beta" version owing to stability and other issues.

I'm thinking that to save time we could set up templates for editorial discussions in the style of football crowd chants, e.g.

Author response: "THE REFEREE'S A WANKER"

Desk Reject: "YOU'RE SHIT AND YOU KNOW YOU ARE"

etc

Are you sure it's not Cthulhu?
The oldest known image of an owl:

More than 30,000 years ago, someone skillfully scratched the figure of a long-eared owl (Asio otus) into the soft outer layer of the walls of Chauvet Cave, France. The owl is looking backward over their wings, head turned 180 degrees

I feel obliged to stand up for the "GenZ" person I know best: he reads very quickly, greatly prefers print to digital, makes notes with pencil and paper, and avoids all social media. IMHO generational generalisation aren't very useful...

#OnThisDay 100 years ago, The Plough and the Stars by Sean O'Casey premiered at the Abbey Theatre.

At its original production in February 1926, the audience rioted. Now regarded as a masterpiece, this provocative play is an essential part of our understanding of Irish history and Irish theatre.

The Newton is a unit of force and it seems the Emerson must be a measure of thickness.

I suggest that the Newton Emerson, having the same dimensions as mechanical work, must measure the work done churning out one of these halfwitted opinion pieces.
