William Thomson, Baron Kelvin Irish engineer, mathematician, and physicist died #OTD in 1907.
Absolute temperatures are stated in units of kelvin in his honour. While the existence of a coldest possible temperature, known as absolute zero, was known prior to his work, Kelvin is known for determining its correct value as approximately −273.15 degrees Celsius. Kelvin's work in thermodynamics led to the idea that energy can not pass spontaneously from a colder object to a hotter object.

Italian astronomer Giovanni Battista Donati was born #OTD in 1826.
Donati was a pioneer in the spectroscopic study of the stars, the Sun, and comets. He observed the total solar eclipse of 18 July 1860, at Torreblanca in Spain, and in the same year began experiments in stellar spectroscopy. Between 1854 and 1864 he discovered six new comets, including the spectacular Comet Donati (C/1858 L1), found in 1858. via @wikipedia
"Here we focus on pseudo-profound bullshit, which consists of seemingly impressive assertions that are presented as true and meaningful but are actually vacuous"

"This Element examines some of their concerns. It uses evidence that critics of peer review sometimes cite to show its failures, as well as empirical literature on the reception of bullshit, to advance positive claims about how the assessment of scholarly work is appropriately influenced by features of the context in which it appears: for example, by readers' knowledge of authorship or of publication venue."

"The authors introduce the two main theoretical approaches in SM, Boltzmannian SM and Gibbsian SM, and discuss how they conceptualise equilibrium and explain the approach to it. In doing so, the authors examine how probabilities are introduced into the theories, how they deal with irreversibility, how they understand the relation between the micro and the macro level, and how the two approaches relate to each other."

"The findings gave a unique understanding of life and death in this early Christian Viking community and indicated that it was common to suffer from dental caries, tooth loss, infections of dental origin and tooth pain. These Vikings also manipulated their teeth through filing, tooth picking and other occupational behaviors."

"This article outlines a chronology for understanding the cultural importance in Britain of this voyage, from the New England chroniclers to the postcolonial critiques of historians today. In between, it offers a thematic analysis of the different groups which could use the story in their construction of morality and identity, from Romanticists and abolitionists to Anglo-American diplomats and civic boosters."

"In his Remarks on the Foundations of Mathematics, Wittgenstein claims, puzzlingly, that ‘the proof creates a new concept’ (RFM III-41). This paper aims to contribute to clarifying this idea, and to showing how it marks a major break with the traditional conception of proof."

"The authors present new archaeological discoveries from western and northern Mongolia, dating to the fourth and fifth centuries AD, including a wooden frame saddle with horse hide components from Urd Ulaan Uneet and an iron stirrup from Khukh Nuur. Together, these finds suggest that Mongolian groups were early adopters of stirrups and saddles, facilitating the expansion of nomadic hegemony across Eurasia and shaping the conduct of medieval mounted warfare."

Milestone: 2023 is the first year with more than 10,000 research paper retractions -- smashing previous records. More than 8,000 of these came from Hindawi (mostly from 'special issues'). Total retractions now >50,000. My analysis for Nature.

When you find a webpage that offers you a book but you can't download it, and you can't right-click to save the images of its pages, well – the page has loaded the images. Therefore the images are somewhere in your browser. What to do?
Knowing a bit of how web pages are structured and built helps make the most of what you see online.
1. In your browser, open the developer tools (push F12).
2. Go to the "Network" tab and restrict the view to "Images" and "Media" (see the upper right side).
3. Zoom into the book to ensure pages are of high resolution, then pass the pages.
4. You will notice new rows appearing into the table of the "Network" tab of the Developer Tools.
5. Now move your mouse over them and the image may even be shown to you; in any case just right-click and save it.
There are scripts online to automate this, but if all you are after are a few pages, this suffices.
To montage the pages into a PDF, use e.g.:
$ img2pdf *jpg book.pdf
... and even OCR them if you like:
$ ocrmypdf book.pdf book-OCR.pdf
Both programs can be installed with:
$ sudo apt get install img2pdf ocrmypdf
... in ubuntu, debian, and the like.
Or, import each into a page of a multi-page #Inkscape document and save it as a PDF.
@deco I use the same method. I am not by any stretch of the imagination an expert, I hope people more knowledgable than me are able to assist you.
@deco When I use this 'system' without hashtags only my toots appear in the results.
@deco I believe if you put the term (without hashtag) you are looking for into the search box the result should show your toots that use that word.
About a quarter of all #freshwater #fish species are at risk of #extinction due to threats from #ClimateChange and #pollution, the latest @IUCNRedList showed on Monday, chart @Reuters https://www.reuters.com/business/environment/quarter-freshwater-fish-risk-extinction-study-2023-12-11/
Not a bot just a chap in his fifties who occasionally reads things.
Toots are humanities, science, non-fiction, books, maps, charts and graphs related. Some toots containing videos may also find their way into the timeline.
Toots or follows or boosts or mentions ≠ endorsements of any particular notion or notions.
