CERN’s Gargamelle bubble chamber was 4.8 metres long by 2 metres in diameter, weighed 1,000 tonnes, and held nearly 12 cubic metres of heavy-liquid Freon. It was inaugurated on 7 May 1971 with a day of speeches, visits and lunch for the journalists and other guests. This short film, made a few months earlier, describes the design, construction and operation of the giantess.
Early results from Gargamelle provided crucial evidence for the existence of quarks, and in July 1973 the Gargamelle collaboration presented the first direct evidence of the weak neutral current. The pictures that made the tracks of particles visible as trails of bubbles, yielding these scientific results, are also extremely beautiful. The one shown dates from 1978; you can see more, and some of their interpretive sketches, here.
Wolfgang Pauli took up his duties as professor in Zurich at the end of April 1928. Before accepting the post he had insisted on the appointment of an assistant, and wrote to Ralph Kronig on 22 November, ‘I would like to ask you, for the moment quite tentatively, if in principle you would agree to accept this position … your task would be:
1. Every time I say something, to contradict me with detailed arguments.
2. To animate somewhat the scientiﬁc activity with modern ideas.
Looking back (this photo dates from 1955), Kronig considered his time in Zurich, ‘not only as one of the most instructive, but also as one of the most exhilarating periods’ of his life. He added, ‘One of my tasks, not agreed upon beforehand, was to watch out that Pauli should limit his consumption of ice cream at Sprüngli’s Konditorei at the Paradeplatz where we often went in the afternoon.'
Pauli thought Heisenberg’s ‘World Formula’ needed a lot more work, and he made his point graphically. He sent this drawing of an empty picture frame to George Gamow on 1 March 1958 with the caption, ‘This is to show the world that I can paint like Titian … Only technical details are missing.’
Pauli and Heisenberg had collaborated for many years, but Pauli was unconvinced by the results of their search for a unified theory of elementary particles, and felt the publicity about it was premature. He died in December of the same year. The letter is online here.
With the availability of new massive digital collections, innovative ways of exploring library data are emerging. Researchers are starting to investigate the use of powerful analysis tools that go beyond what the human eye can see, beyond what the human mind can process. Text and data mining techniques offer new opportunities for new types of research. Since a few years now, the BnF has seen its digital collections driving the interests of the early-adopters of new data management tools. These digital studies may be at the core of our users’ practice in the future; they may become instrumental in defining what a national library is. That’s why in 2016, the BnF started within its 4-year internal research programme a new project called CORPUS, aimed at designing a future service for providing access to digital corpora for researchers.
Emmanuelle Bermès is deputy director for services and networks at BnF since 2014. From 2003 to 2011, she worked at the National library of France (BnF), first in digital libraries and digital preservation, then in metadata management. From 2011 to 2014, she was in charge of multimedia and digital services at the Centre Pompidou (Paris, France). She has held a number of responsibilities at international level: within Europeana, the W3C, IFLA and the International internet preservation consortium. Among other charges, she is the coordinator for the Corpus project within the BnF.
Wolfgang Pauli received his habilitation from the University of Hamburg in 1924 – the same year he discovered his Nobel-Prize-winning exclusion principle – and delivered his inaugural lecture on 23 February. He was awarded the title of professor in 1926, then obtained a professorship in theoretical physics at the ETH, Zürich, in 1928. His tendency to forget about the audience, and think out problems as he went along, proved challenging for some students. But, as Markus Fierz pointed, they at least learned to think critically about a theory!
Both platforms focus on scientific collaborative authoring: Overleaf is an online LaTeX and Rich Text collaborative editor and publishing tool and ShareLaTeX is an online LaTeX collaborative editor and reviewing tool. Their rich feature set includes: pure LaTeX editor, rich text editor (Overleaf only), real-time collaboration, real-time PDF preview, author comments, track changes (ShareLaTeX only), version control (w/ Git access) and export as PDF & LaTeX.
Overleaf and ShareLaTeX are joining forces, bringing their teams and services together as they continue to build great tools for collaborative authoring. Over the coming months, they will be working on merging Overleaf and ShareLaTeX together into a single service while making the transition as smooth as possible.

Future Nobel laureate Wolfgang Pauli was a little over six-and-a-half years old when this photo was taken in December 1906. His biographer Charles Enz notes that that young Wolfi contracted all the usual childhood diseases and, to use the typically Viennese expression, es war ihm immer fad – he always felt bored.
By the age of four he was already adept in the art of contradicting his elders that would later help him to reshape modern physics. On being told during one of his walks through Vienna, ‘Now we are walking over the Danube Canal', he replied firmly, ‘No, Aunt Erna, this is the Wien Canal, which flows into the Danube Canal.’
