ICYMI, here is the press release for my study with @drjuliawester.bsky.social - we surveyed over 800 scientists who use social media. They overwhelmingly agree that Twitter is no longer useful or pleasant, and that for all professional online scientist goals, Bluesky is superior.

Statistics on how scientists feel about their presence on Bluesky versus Twitter. My personal experience (before closing my Twitter account in August 2023) was that engagement for my tweets had dropped to close to zero. No longer worth the effort...

Congratulations to Philippe Aghion on receiving the Nobel Prize in economics.

A proud moment for Europe and a strong reminder that innovation and openness are the foundations of our shared prosperity.

Philippe’s contributions helped shape Mario Draghi’s vision for European competitiveness.

Correct! Your memory is better than mine.

If you teach any course that involves working with RStudio or any software for which files and folders matter:

Be prepared to spend a good hour to teach students what’s a file and a folder, folder hierarchy, and things like this

Smartphones and apps have abstracted these technicalities

I hope philosophers of science will chime in on the Prize Committee's discussion about kinds of knowledge, and its dissemination, as drivers of innovation and competition: www.nobelprize.org/uploads/2025... #PhilSci #NobelPrize

Useful knowledge
So – what creates this sustained economic growth? This year’s laureates used different methods to
answer this question. Through his research in economic history, Joel Mokyr has demonstrated that
a continual flow of useful knowledge is necessary. This useful knowledge has two parts: the first is
what Mokyr refers to as propositional knowledge, a systematic description of regularities in the natural
world that demonstrate why something works; the second is prescriptive knowledge, such as practical
instructions, drawings or recipes that describe what is necessary for something to work.
Mokyr shows that prior to the Industrial Revolution, technological innovation was primarily based on
prescriptive knowledge. People knew that something worked, but not why. Propositional knowledge, such
as in mathematics and natural philosophy, was developed without reference to prescriptive knowledge,
which made it difficult, even impossible, to build upon existing knowledge. Attempted innovations were
often haphazard or had approaches that someone with adequate propositional knowledge would have
understood were futile – such as building a perpetual motion machine or using alchemy to make gold.
