A lovely meal the other day in Porto with newlyweds 🎊 Miguel & Maria, where Maria introduced us to a few traditional Portuguese desserts such as "Bacon Pudding" & "Camel Drool" 😂 🐫🐪

Summer School: The Aim and Structure of Cosmological Theory A number of challenging questions arise in contemporary cosmology, and philosophers can contribute constructively to answering them. Over the past century cosmologists have debated whether, for exampl...

Very excited for this summer school on my forthcoming book with Chris Smeenk, The Aims and Structure of Cosmological Theory!!

The book is very nearly finished. Let us know if you'd like to give feedback on a draft.

I would read a draft for sure. Congrats to you and Chris! (I would have wanted to attend the summer school, too, under normal circumstances, but it's just been too hectic relocating my life to the States this year).

Co-organized with @wmyrvold.bsky.social, the 2025 Foundations of Thermodynamics workshop will be held in NTU from 16-18 July 2025. We have a great slate of participants and I am very much looking forward to it!

Attendance is free and there will be a Zoom option. Details here: bit.ly/3SxvSNi

@miguelohn.bsky.social is staying with us for week, so today took him on hike to top of Great Blue Hill to see weather observatory where they've continuously used same historic instruments since #19thC, such as this Campbell-Stokes sunshine recorder. Then walked along @neponsetgreenway.bsky.social

Congrats, David!

Great that you will be in Boston!

The only possible way to round off the @ri-science.bsky.social Geophysics conference was to stick the attendees in Faraday’s lab 🤷🏻‍♀️ Thank you all so much for coming! @miguelohn.bsky.social @alisabokulich.bsky.social

Had a fantastic time yesterday at Ri as part of the "Decoding our Planet" workshop beautifully organised by @katysduncan.bsky.social and @miguelohn.bsky.social

Thank you @katysduncan.bsky.social and @miguelohn.bsky.social for convening such a wonderful discussion meeting on #histsci and #geophysics at @ri-science.bsky.social, and a great keynote from @naomioreskes.bsky.social

Naomi giving talk at historic Royal Institution lecture hall: Slide text: • 1920s, Vening Meinesz had pioneered precision measurement of gravity at sea. • Dutch "East Indies" • Large band of negative gravity anomaly, along the line of the Java trench. • Coincided with zone of major earthquakes, & a parallel narrow zones of active volcanoes

A wonderful talk tonight by @naomioreskes.bsky.social at the @ri-science.bsky.social on how Navy secrecy of oceanographic data impeded rise of plate tectonics.

Oh no - I hope you made it here eventually!!

I'm glad to be one of the contributing museum professionals at this

May 9, 2025 Workshop Program: Decoding Our Planet: The Making of Geophysics

On Monday, the Royal Institution is hosting a workshop on the #histsci of geophysics, with a livestreamed keynote by @naomioreskes.bsky.social on plate tectonics.

Read @katysduncan.bsky.social on how she and @miguelohn.bsky.social put the event together, and see who's presenting here:

Rethinking the origins of plate tectonics Naomi Oreskes explores how our understanding of the planet has been shaped by money.

Think you know the history of plate tectonics? Think again 🌍
@naomioreskes.bsky.social explores why the US military shrouded this science in secrecy & what this reveals about scientific progress, politics and power…

Decoding Our Planet: The Making of Geophysics How did we come to understand the origin and basic physical processes of our planet? Answering this question requires us to understand the origins of modern geophysics, the science investigating everything from gravity and magnetism to earthquakes, climate change, and plate tectonics. The best place to answer this question is at the Royal Institution, where most major geophysicists discoursed, debated, and corresponded. In this workshop, we bring together leading scholars from history of science, and geophysics, and philosophy of science to explore how modern geophysics took shape in the nineteenth and twentieth century. This event is held in conjunction with Discover200 - a celebration of the Ri's 200 year history of its Discourse series, CHRISTMAS LECTURES, and the isolation of Benzene We are incredibly grateful to the Freer Trust, the Department of History and Philosophy of Science (University of Cambridge), and individual attendees for their generosity in funding this event. Thank you! All talks are in the Conversation Room (see attached floorplan) unless otherwise specified. Talks are 25 minutes and 10 minutes Q&A.

took shape in #19thC & 20thC, at the Royal Institution in London 12 May

congrats to @stsucl.bsky.social - great choice!

Congratulations @jakobortmann.bsky.social ! This started as the MPhil dissertation in Cambridge HPS, right?

Thank you both :)!!

Only a *little* while since the end of the project, I'm delighted that the Board of Longitude book is available for order (publication date 17 April), and that it is a relatively modest £32 in paperback! #histsci www.cambridge.org/gb/universit...
