The entirety of the tournament has been archived in a Google Doc for posterity: docs.google.com/document/d/1...

I may try to create a neater PDF version once I’ve caught up on the rest of my life.

pre-writing a devastating obituary for your enemy is god-tier hating of a kind you don’t often see anymore. renaissance haterism. beautiful stuff.

A Sharon Begley byline, almost 5 years after her death.

Upon hearing the news James Watson had died, a STAT reporter said in our Slack, "I wish I could read what Sharon would have written."

Incredible news: Sharon in fact did pre-write a Watson obit. And it is masterful and excoriating.

James Watson, dead at 97, was a scientific legend and a pariah among his peers

I am aware of at least 37 different published metrics of this type that try to account for co-authorship in publications and this plug-in represents none of them, so I guess that makes at least 38.

The bigger question: why is Nature wasting space even talking about a random useless tool?

Michael Rosenberg @mrosenberg.bsky.social · 15d

It's not just bad, it's completely arbitrary. Dozens of papers have been written trying to solve this "problem" (assuming you think it is one in the first place) and this plugin just makes up yet another approach. There can never be an automated solution because there is no standard for author order

For the record, I am tired of everyone on Bluesky comparing the new plans for the White House to fiddler crabs.

This is extremely insulting to fiddler crabs, who did absolutely nothing to deserve this. 🦀

Atlantic sand fiddler crab. #AtlanticSandFiddlerCrab #UcaPugilator #SandFiddlerCrab #FiddlerCrab #Crab #Arthropod #Animal #Nature #Photography #TECOManateeViewingCenter #ApolloBeach #Florida

An Atlantic sand fiddler crab in the sand. The crab is just to the right of a small hole in the ground. The shell, or carapace, is mostly white with a few black spots and also is pink in the center, which identifies it as a displaying male. The eyes are hard to see in this photo but are at the end of small stalks. The right claw is considerably larger than the left. It is a light brown with many small bumps on it. The legs are orange.

Yesterday’s inktober was wholly an experiment - “rivals” blue and orange water based inks drawn onto damp paper #inktober #inktober2025

Fuzzy drawing of two fiddler crabs competing. Blue and orange ink line drawing on white paper but the lines have bled and diffused away from where they were originally drawn and hazy colour has washed across the surface

I honestly didn't realize MTV channels still existed.

It's kind of like when you hear about a celebrity death and your first reaction is "Wait...they were still alive?"

Note that v could be an imaginary number in the imaginary case one actually find the material interesting, in which case time would shrink and the lecture would appear to end faster than it actually does.

Michael Rosenberg @mrosenberg.bsky.social · Oct 8

Based on this we can determine that the large 1 hour and 20 minute lecture with v = 0.9c, appears to last 3 hours and 4 minutes, the 50 minute seminar with v = 0.75c appears to last 1 hour and 16 minutes, and the 15 minute conference presentation with v = 0.8c appears to last 25 minutes.

Michael Rosenberg @mrosenberg.bsky.social · Oct 8

Since the actual time (dT') is measured by the lecturer, the apparent length of time according to your mental reference frame (dT) dilates and becomes longer than the actual time. According to the relativity formula, dT = dT' / sqrt(1 - v^2/c^2).

Relativity formula, delta T equals delta T prime divided by the square root of 1 - v squared divided by c squared

Michael Rosenberg @mrosenberg.bsky.social · Oct 8

Because your knowledge is remaining relatively stationary while the lecture is shooting ahead astronomically, you view the lecture from a different frame of references than it actually occupies.

Michael Rosenberg @mrosenberg.bsky.social · Oct 8

Large values of v indicate material presented very quickly or which is very boring. Careful empirical analysis has indicated that for large lectures, v is approximately 0.9c (where c is the speed of light). For departmental seminars is is ~0.75c and for conference presentations ~0.8c.

Michael Rosenberg @mrosenberg.bsky.social · Oct 8

The length of a lecture according to your mind is dependent on the confusion-boringness factor, v. This represents the relative speed at which your brain can absorb the material versus the speed at which is presented, corrected by the level of boredom generated by the lecture style and material.

Michael Rosenberg @mrosenberg.bsky.social · Oct 8

Why lectures seem to last forever?
An explanation based on the time dilation principle of Einstein's special theory or relativity (1905).

Note 1: Also applies to many other types of presentations.
Note 2: I originally came up with this idea 35 years ago, after one week as a freshman college student

I spot checked a number of additional academic books, including some I wrote chapters for, and found them included as well. I am not personally eligible for a claim on those works, but the editors and publishers are.

RIP to Jane Goodall, who was cool with this Gary Larson FAR SIDE strip from 1987:

A Gary Larson FAR SIDE cartoon from August 1987, where a glasses-wearing female gorilla is picking a hair off of her mate's back and saying, "Well, well -- another blonde hair. ....Conducting a little more 'research' with that Jane Goodall tramp?"

This is true. But also not permanent. Given time and multiple molts, they will eventually regrow a claw as strong as the one that was lost.

Fun fact: male fiddler crabs have 1 GIANT claw. If the claw gets severed, they can grow a new weaker one. Other crabs cant tell the diff so may surrender to a weaker claw if it looks big
