Our current Gold exhibition explores the use of gold in books and documents around the world. This blogpost looks at gold from a scientific perspective, and why it has the properties that have caused it to be so valued throughout human history.

Gold is probably the first metal to be known to humans. Unlike other metals, which need to be extracted from their ores, gold exists in the environment as the metal itself, from tiny specks up to large nuggets. This is because it rarely reacts with other chemicals, which also explains why it does not tarnish in air like silver or rust like iron. The oldest gold items in the exhibition are two gold plaques, with shelfmarks Or 5340 A and Or 5340 B, with inscribed Buddhist scriptures in Pali. They were discovered buried at the base of a stupa in Maunggan in Myanmar and are dated to the 5th or 6th centuries CE.

The Buddhist gold plaques

Because of its lack of corrosion, gold has been seen as mystically special, and used for objects of high prestige and to make coins. One notable object in our exhibition is the treaty between the rulers of the Indian city of Calicut (now Kozhikode) and the Dutch, which was inscribed into a two-metre-long strip of gold. Gold was used to symbolise the importance of the treaty but also for practical reasons, as a material that would not rot or decay in a tropical climate.

The reason why gold is so unreactive is because of the number of electrons in each atom. This is the same as the number of protons, and it is this which decides which element an atom is. Within atoms, electrons are arranged in layers called "shells", and gold is particularly unreactive as its outermost shell is full of electrons, which is a particularly stable state for an atom.

Unlike some atoms with full outermost shells, like helium and neon, gold can react with some other chemicals. This is because gold can lose one to three electrons if the reaction can release enough energy to strip them off - called "oxidation", and it can also share electrons with other atoms, without giving up any of its own.

The first material to be discovered by medieval alchemists which can react with gold is the famous aqua regia, Latin for "king's water". Despite the appetising-sounding name, this is very dangerous and you should not try this at home - it is a very corrosive mixture of concentrated hydrochloric acid and nitric acid in water. Because of the hydrochloric acid, the mixture contains chloride ions, which are chlorine atoms which have received an extra electron from the hydrogen atoms in the water. The chloride atoms can share their electrons with the gold atoms to create what are called complexes, and this makes it easier for the nitric acid, which is an oxidising agent, to strip electrons away from the gold atoms, creating gold chlorides which dissolve in the water. Gold compounds do have some uses, such as treating arthritis and in some kinds of traditional silver-based photography.
Fortunately aqua regia doesn't occur naturally, so our gold exhibits are perfectly safe.

Our Gold exhibition is open from Friday 20th May 20 Sunday 2nd October 2022, and you can book tickets online to visit.

The COP26 conference in Glasgow has ended, but the real work of reducing carbon emissions must now begin. The science staff and the British Library Green Network have created a collection guide now available on our website, which includes key items to provide information on the problems and potential solutions.

The guide includes books, journals and online databases that you can only access within the British Library if you have a Reader Pass, but there are also many links to trustworthy websites that contain a wealth of information on climate change, the Earth's climate, and the wider issues.

We will be keeping it up to date so that it will continue to be useful into the future.

"Garden cucumber" from Blackwell's Herbal, British Library 34.I.12 -13

Some of our earliest high-quality digitised manuscripts and printed books are now available again through our website for anybody to read. They were digitised from the mid-1990s on, using the "Turning the Pages" software created by the Library in collaboration with Armadillo Systems. You might remember seeing them on stand-alone electronic consoles in various parts of the Library. The digitisations include realistic animations of the pages being physically turned and laid down.

Some of the items involved are important in the history of science:

• The complete Codex Arundel, a collection of pages from the private sketchbooks and notebooks of the Renaissance polymath Leonardo da Vinci, predominantly dealing with physics.
• Highlights of Andreas Vesalius's "De Humani Corporis Fabrica", the first modern anatomical textbook, with artwork thought to be by the studio of Titian.
• Highlights of Elizabeth Blackwell's "A Curious Herbal", the first British herbal by a woman, created in the 1730s to buy her ne'er-do-well husband out of debtors' prison.
• Highlights of John James Audubon's famed "Birds of America".

We are happy to announce that this week we have acquired the Wiley Digital Archives of several major learned societies. The collections currently available are those from the New York Academy of Sciences, the British Association for the Advancement of Science, the Royal Geographical Society, the Royal Anthropological Institute of Great Britain and Ireland, and the Royal College of Physicians. The database also includes scientific material from major British universities, digitised as part of the BAAS project.

Information in the archives includes field notes on Hausa Islamic law, beginners' lessons in the Mole language spoken in parts of Ghana, research for a government investigation into early-Victorian mine ventilation, reports on an earthquake in Erzerum, Turkey in 1859, a recipe for a "very rare and excellent" seventeenth-century "wound drink", and a huge range of maps. The Royal College of Physicians collections include a number of digitised incunabula and medieval printed books. For those items which might be harder to read, automated transcriptions are available.

Unfortunately the database cannot currently be used from outside the Library, but we are open again and any reader with an interest in the history of science is highly recommended to come in and try it out.

In August 1957, a 33-year-old Donald Michie travelled across Europe to visit Moscow. The journey was a remarkable one. Driving through Germany and Poland in a 1948 Standard drop head coupé with his friend from Oxford, John Matheson, the pair had lively encounters with enthusiastic locals, a Polish hitchhiker, and even an offer for their car from a film director in Russia.ⁱ

Whilst visiting the Institute of Genetics in Moscow, Michie had a chance encounter with Trofim Lysenko, the infamous Soviet geneticist. Seizing the opportunity, a five-hour interview between the two and Lysenko’s colleagues ensued, with a transcript and reports following in British publications over the following 12 months. What had started out as the tour of a young socialist had turned into a golden chance to meet and interrogate the man at the centre of one of the greatest scientific controversies of the twentieth century.

The British scientific community was rocked in the 1940s and ‘50s by the rise of Lysenko to Director of the Institute of Genetics in Moscow. His theories and methods (both scientific and as a political figure) prompted resignations from scientific societies, radio broadcasts and journal articles denigrating him, and no small degree of infighting as people attempted to separate the emerging Cold War political divide from the scientific merits (or demerits) of his work. Michie, as a young geneticist forging his career in this time, found himself at the heart of this.

Lysenko was a neo-Lamarckist, arguing that characteristics acquired in response to the environment an organism lives in could then be passed on to future generations. The traditional view of the 1950s, based on the work of Gregor Mendel, was that the environment’s role was limited to accelerating or slowing down random mutations of genes. Lysenko’s belief in this view was not the only factor in driving controversy. The international scientific community was also concerned by the state endorsement of his science within the Soviet Union, prompting the disappearance, side-lining, or death of prominent critics, such as N. I. Vavilov. Lysenko’s precise liability remains an issue of contention to this day.

Michie’s visit to the Institute of Genetics. Left to right: Kosikov, Ružica Glavinic, John Matheson, Trofim Lysenko, Nuzhdin, Anne McLaren and Donald Michie. Reproduced with permission of the estate of Donald Michie.

Michie was carving out his career in genetics in the 1950s. By 1953, he had finished his DPhil in mammalian genetics under the supervision of E. B. Ford at Oxford. He then moved to work as a researcher at UCL alongside notable figures such as J. B. S. Haldane, Michie’s second wife and celebrated biologist Anne McLaren, and future Nobel Prize winner Peter Medawar. Michie had already dipped his toe in the waters of the Lysenko debate in a remarkable exchange of letters to an obscure rabbit breeders’ magazine, Fur and Feather, showing himself unafraid to side with controversy as he argued in favour of testing Lysenko’s theories.ⁱⁱ

First page of Donald Michie, ‘Interview with Lysenko’, Soviet Science Bulletin, V (1 & 2, 1958), 1-10. Add MS 89202/11/6

The interview with Lysenko revolved around a major theme from Michie: would Lysenko be prepared to share his methods, publish work in English and permit exchanges of personnel with Western institutions? Michie’s belief was that differences between the West and Soviet Union could be overcome through collaboration and openness, fostering a spirit of sharing knowledge. Lysenko agreed with the sentiment, responding:

I do not agree with this division into Western genetics and Soviet genetics. Science is unitary. I believe, and my colleagues believe, that science knows no frontiers.ⁱⁱⁱ

Both Michie and Lysenko argued for letting scientific results win the debate, however they understood the obstacles in the way of that outcome rather differently. Lysenko saw bad faith and entrenched attitudes from Western scientists, believing them unwilling to entertain the possibility of Soviet scientists producing good research. Michie saw barriers to accessibility, such as the poor understanding of the Russian language in the West. He criticised the stubbornness of Lysenko and his colleagues to share their techniques and offer work for publication in English journals, whilst also castigating Western scientists for not engaging with the science and testing it rigorously and with an open mind.

Ultimately, Michie concluded from his meeting with Lysenko:

The only certain remedy that I can see is to reunite the genetical profession in a single scientific brotherhood irrespective of politics, nationality or genetical creed. … In more definite terms, Soviet and East European biologists must be willing to publish in Western journals and vice versa.^iv

The question which follows is: Did Michie’s interview impact Lysenko’s reputation in Britain?

The short answer is probably not. For instance, Michie drew upon Lysenkoist scientists in a remarkable 1958 essay reflecting on 100 years since Charles Darwin’s On the Origin of Species.^v The references to Lysenkoists were not well-received by reviewers, with them finding Michie’s piece out of step with the tone of the other essays in the collection. Lysenko’s reputation was, at least in the late 1950s, still entrenched negatively in the Western scientific world.

Shortly after these interventions, Michie drifted away from the world of genetics to pursue his long-standing interest in computers and artificial intelligence following his move to the University of Edinburgh in 1958. As such, his contributions on Lysenko petered out. He would go on to become one of the pioneers of artificial intelligence research in the United Kingdom. Never one to shy away from controversial topics, he found himself at the centre of the heated Lighthill debate in the 1970s concerning the funding of AI projects.

Lysenko’s reputation has largely remained contentious in the UK. Whilst there have been attempts to rehabilitate his science and separate it from his political reputation, such as by Chinese scientist Yongsheng Liu in the early 2000s, there is still a great deal of baggage associated with Lysenko.

Reflecting on the Lysenko controversy nearly 50 years later, Michie remarked:

Perhaps history is not after all a documented story of what probably happened. Rather, perhaps history is whatever tale of mystery and imagination becomes in the end too embedded to set straight.^vi

Whilst this may have been one tale which Michie could not set straight, his open-mindedness and commitment to scientific exchange as an early-career researcher are admirable and fascinating to see in the face of such a controversial and fraught debate.

The past year has seen many a new word popping up in our languages: Furlough (from the Dutch ‘verlof’ or paid leave), social distancing, lockdown, you name it. Most of these have ‘gone viral’, just like the virus itself. And just like the virus itself the word ‘virus’ mutated over time.

The word ‘virus’ was long known in science, but it was not used to describe the pathogen we know it to be. That was the work of Dutch biologist Martinus Willem Beijerinck.

Portrait of Martin Willem Beijerinck, Wikipedia Commons

Beijerinck was the third of three scientists who had worked on the tobacco mosaic disease, an infection that could devastate whole crops. He continued the work done on the disease by Adolf Mayer, former Director of the Agricultural Experiment Station at the Agricultural School in Wageningen where he himself was based. Meyer found that if a bacterium was the cause, there was something strange going on but he could not figure out what it was.

The next step in the right direction was made by Russian botanist Dmitrii Ivanovsky He concluded that the tobacco mosaic disease is caused by something much smaller than a bacterium, because it had slipped through the finest filters of the time, that no bacterium could cross.

He published his findings in several publications, amongst which was an article entitled ‘Die Pockenkrankheit der Tabakspflantze’, published in Mémoires de l'Académie Impériale des Sciences de Saint-Pétersbourg in 1890.

Apparently this was not picked up by our third man, Beijerinck. He conducted similar research on the tobacco mosaic disease as Ivanovsky had done, but concluded there had to be a new form of infectious agent. Because it was soluble in water Beijerinck called it Contagium vivum fluidum and he called the pathogen ‘virus’ to distinguish it from bacteria.

He also suggested the new idea that viruses were only capable of reproducing in cells of other organisms. His hypothesis was confirmed a few years later, when electron microscopes became available. I am not sure whether Beijerinck lived to see this new type of kit, because he died in 1931, the year it was invented.

We are very happy to hear that zbMATH, one of the most important bibliographic databases in the field of mathematics, is now freely available to all online. The database is run by FIZ Karlsruhe, the European Mathematical Society and the Heidelberg Academy of Arts and Sciences, and the funding to make it free to all was provided by the Joint Science Conference, the German national government organisation for science research funding and policy.

The database covers mathematics books and scholarly articles comprehensively since 1868, with some items from considerably earlier. It includes material from the paper abstracts journals Jahrbuch über die Fortschritte der Mathematik (1868-1945) and Zentralblatt für Mathematik (1931-2013). It can be searched by author and subject as normal, but also includes searching by mathematical formula and the subject-specific Mathematics Subject Classification. It includes not just abstracts, but independent reviews of the significance of important articles, although some of these are in German rather than English. It also has both forward and backward citation data. Where possible links to the online full-text item are provided.

The administrators are currently working on developing an API to allow content from zbMATH to be used in other digital information systems on an open access basis.

Anybody with an interest in mathematics is heartily recommended to try it out.

A page from "Tsurat ha-arets"

Our Hebrew manuscripts exhibition continues until next year. You might not expect it to have a whole section on science, the prize of which is the manuscript numbered Or 10721, a copy of Tsurat ha-arets ("Form of the Earth") by Abraham bar Hiyya, with some additional works. It is thought to have been transcribed in the 15th century by one Joseph ben Se’adyah Ibn Hayyim. It is fully digitised at http://www.bl.uk/manuscripts/Viewer.aspx?ref=or_10721_fs001r.

Or 10721 was purchased in 1924 by the British Museum Library from the Romanian-British Jewish scholar, and Chief Rabbi of the English Sephardic community, the Rev. Moses Gaster, as part of a large collection known as the "Gaster Manuscripts". Bar Hiyya (1070?-1136) lived in Barcelona during the period of Moorish rule in 11th-12th centuries and was considered the foremost scientific authority of any background in Spain at the time. He probably introduced Arabic algebra into Middle Ages Europe, and his work was key to Fibonacci's introduction of the Hindu-Arabic number system into Christian Medieval Europe, which allowed modern maths to begin there. He published the first general solution of quadratic equations and wrote the oldest known mathematical work on the Hebrew calendar. His book Hegyon ha-Nefesh is considered to be the oldest surviving book on philosophy in the Hebrew language. Outside his scholarly studies, he held the government legal position "sahib al-shurta" of the Taifa of Zaragoza, a kingdom of the era that ruled a large part of Eastern Spain.

Bar Hiyya was the first major figure of Jewish scholarship to use Hebrew rather than Judeo-Arabic for scientific works. He developed a new vocabulary for science in the language and translated many existing Arabic scientific works into Hebrew, to improve what he considered to be the very poor state of mathematical knowledge among Spanish and French Jews of the era.

Tsurat ha-arets is a treatise on cosmology and geography describing the Ptolomaic or Earth-centred view of the universe, generally accepted in Middle Ages Europe. It also describes the division of the known northern hemisphere into seven "climates", or regions divided by east-west lines of latitude.

An earlier post on our Collection Care blog has described the most recent conservation of the manuscript.

18th July 2020 is the three hundredth anniversary of the birth of Gilbert White, the "parson-naturalist" best known for his pioneering work on the natural history and history of his parish of Sherborne, Hampshire. A number of posts are appearing on different British Library blogs to celebrate, but this post will discuss his influence on science to this day.

Prior to White's work most scientific biology was based around the study of dead or captive animals in scientists' studies. White, who has been described as "the first ecologist" preferred to observe the animals and plants around his home, over long periods of time. These practices inspired Charles Darwin, whose observations of the finches of the Galapagos Islands initially inspired his thoughts about evolution by natural selection. On a more popular scale, White's influence is seen by some as creating birdwatching as a hobby.

Although more laboratory-centric biologists have occassionally dismissed White-style naturalism as dilatanttish or twee, it has become increasingly important since the mid-twentieth-century, especially in the study of environmental conditions, and of animal behaviour - "ethology".

One of the oldest sites of long-term nature-observation studies in Britain has been Wytham Woods in Oxfordshire. Nicknamed the "laboratory with leaves", it was donated to Oxford University in 1942 by Colonel Raymond ffenell, although some observation had been carried out there since the 1920s. Colonel ffennell was a member of the wealthy and socially prominent German Jewish Schumacher family, who had become rich through his involvement in the South African gold-mining industry, and adopted his wife's surname to avoid anti-German prejudice during World War I. Ever since, a host of research projects have been carried out there on all kinds of animals and plants, as well as climate and soil conditions.

One of the most important discoveries to have been made through long-term environmental observation was the discovery of the damage caused to the environment by acid rain in North America, which came from Gene Likens' observational work at the Hubbard Brook Experimental Forest in New Hampshire, beginning in the 1960s.

A listing of current long-term environmental observation sites is maintained by the International Long Term Ecological Research Network (ILTER) on their database DEIMS-SDR (Dynamic Ecological Information Management System - Site and Dataset Registry). See also the review article by Hughes and others with links to many examples.

The modern science of animal behaviour, or ethology, was developed in the 1930s by Nikolaas Timbergen, Konrad Lorenz, and Karl von Frisch. All three did most of their research on domestic or captive animals, but the discipline would later see the importance of long-term observation of the behaviour of wild animals in their natural habitats. Three of the most famous practitioners of this were the so-called "Trimates", known for their observations of wild apes - Jane Goodall with chimpanzees in Tanzania, Dian Fossey with gorillas in Zaire and Rwanda, and Birute Galdikas with orang-utans in Indonesia. Another example which has achieved fame outside science, although not yet enough, is Dave Mech's disproof, from observations of wild wolves in Minnesota, of the outdated "alpha wolf" model of social dynamics in wolf packs, which has influenced a great deal of beliefs about dog-training and even human interactions, but was derived from observations of what turned out to be disfunctional behaviour in captive animals.

It is also possible to follow in White's footsteps yourself, by taking part in a citizen science project based on observing nature in your garden or in your wider local area. The Countryside Jobs Network maintains a list of opportunities, which aren't just in rural areas.

We hope that you look a bit more closely at the nature around you this weekend!
