Food for Thought: Food Technology resources at the British Library

Do you need to explore molecular gastronomy or research the food industry or trends in the beverage business? Are you concerned with global food security, safety  and supply? Are genetically modified foods a threat to our health and ecosystems or a benefit of biological research? What are the markets for different types of food and what is the impact of European regulation on these markets? These questions and many more can be explored by undertaking research at the British Library.

Illegal substances or aiding physical excellence? A few historical perspectives

Ahead of next week's TalkScience event on Doping in Sport Julian Walker explores some historical examples of performance enhancement described in his new book "The Roar of the Crowd".

The essence of the debate regarding the use of drugs in sport is: what is an unfair substance to use, and how do we decide? The F60146-12dividing line between acceptable and unacceptable is, and for decades has been, constantly moving. For the lay-person the terms ‘anabolic steroids’ and ‘human growth hormones’ sound warning bells, but the equally prohibited ‘diuretics’ sound relatively harmless, and the word ‘stimulants’ requires detailed specification to the point where the word itself is more or less meaningless. How does the cultural history of sport handle this subject?

In Book 23 of Homer’s Iliad the funeral games held for Patroclus include a boxing match and a wrestling match. When the boxing match is announced forward comes Epeues, who has certainly done his mental preparation:

"I boast myself To all superior"

His endorphins are running and performance-enhancing even before he has a challenger, his control of the mind-game as assured as Ferguson’s or Mourinho’s. He is answered by the equally confident Euryalus. The fighters each dress for the fight, and:

"Mingling with fists, to furious fight they fell;

  Dire was the crash of jaws, and the sweat stream'd

  From every limb"

Eurylaus looks for an opening but effectively the fight is over with a single blow from Epeues, and he is taken away, spitting blood.

The wrestling bout is more of a match, Homer pitting brain against brawn, Ulysses against Ajax, neither managing to lift and throw the other. Ulysses then enters the running match, against Oiliades. It’s a close thing, Ulysses is probably tired from the wrestling, and it looks like he is going to lose:

"Oiliades

  Led swift the course, and closely at his heels

  Ulysses ran. Near as some cinctured maid

  Industrious holds the distaff to her breast,                  

  While to and fro with practised finger neat

  She tends the flax drawing it to a thread,

  So near Ulysses follow'd him, and press'd

  His footsteps, ere the dust fill'd them again,

  Pouring his breath into his neck behind,                      

  And never slackening pace.[1]"

At this point Ulysses uses the Ancient Greek equivalent of a performance-enhancing drug – he calls on Minerva for help; and sure enough she trips his opponent so that he falls face-down in some cow-poo (ironically his prize for coming second is an ox). Quite blatantly Ulysses has use external assistance to gain victory, and got away with it. Oiliades puts in a complaint:

"Ah--Pallas tripp'd my footsteps; she attends                

  Ulysses ever with a mother's care."

And what happens?

    "Loud laugh'd the Grecians."

It’s a disgrace.

Robert Burton explores, in The Anatomy of Melancholy (1652), the role of exercise in balancing the body. He notes the Roman physician Galen’s contention that ‘to play at ball, be it with the hand or racket, in tennis-courts or otherwise, … exerciseth each part of the body, and doth much good, so that they sweat not too much’[2]. Burton here points out the control on exercise – do it to a certain level of sweating, but stop there; earlier he says that exercise should be done ‘after he hath done his ordinary needs, rubbed his body, washed his hands and face, combed his head and gargarised [gargled]’. These are physical and mental preparations, getting the body empty (I take this to be the meaning of ‘done his ordinary needs’), clean and warmed, and knowing exactly how far to go. While not explicitly involving the ingesting of external substances, they do indicate that exercise does not stand in isolation: the mind and body are made ready for maximum benefit by specific preparation.

F60146-17The pre-match preparation of Captain Barclay, the early nineteenth-century endurance athlete, pushed this process further, and was carefully described by Walter Thom in Pedestrianism (1813). Using Barclay as a model, Thom offers a regimen for the preparing athlete, beginning with ‘a regular course of physic, which consists of three dozes [doses]. Glauber salts are generally preferred’. Glauber salt, sodium sulphate decahydrate, is named after Joseph Glauber, who isolated it in 1625, and named it ‘sal mirabilis’ for its supposed medicinal properties; it was used as a purgative (laxative), and is currently deemed acceptable. Thom’s diet list for the aspiring athlete starts with ‘beef-steaks or mutton-chops under-done, with stale bread and old beer’, and goes on to prohibit any ‘preparations of vegetable matter’ other than ‘biscuit and stale bread’. Prohibited foods include veal, lamb and pork, vegetables, as well as fish, butter, cheese, or milk. Profuse sweating is required, induced by running four miles in flannel at top speed, followed by the imbibing of ‘sweating liquor’, made from caraway-seed, coriander-seed, and liquorice, boiled down in cider, after which the athlete is ‘put to bed in his flannels, and being covered with six or eight pairs of blankets, and a feather-bed’ for about half an hour. As regards hydration ‘water is never given alone … avoid liquids as much as possible, and no more liquor of any kind is allowed to be taken than what is merely requisite to quench the thirst’.

While none of these steps, however eccentric, look ethically dubious, they do make up a massive control regimen for the enhancement of the athlete’s performance. The commodified successor to Capt Barclay’s ‘red-meat & no veg’ diet was Vin Mariani, the so-called ‘athlete’s wine’, launched in 1863. This popular concoction of red wine and coca leaves, whose stimulant properties were praised by the mostly sedentary great and the good, also happened to aid endurance for athletes and cyclists. Cocaine is now, of course, a banned substance for athletes, but Capt Barclay’s coriander-seed and caraway-seed are both diuretics.

By the end of the 19th century training itself, in some circles, was deemed unsporting. When Blackburn Olympic had the temerity to beat the Old Etonians in the 1883 FA Cup Final the Eton College Chronicle wrote,

‘So great was their desire to wrest the Cup from the holders that they introduced into football a practice which has excited the greatest disapprobation in the South.  For three weeks before the final match they went into a strict course of training …’

Blackburn Olympic won 2:1 after extra time. Somehow the Old Etonians had not noticed that the goalposts had moved.

F60104-57

But that perhaps is the question: when we come to look at acceptable or unacceptable substances, can we compare them to laxatives, diuretics, diets and sweating regimes, training or neglecting to train, or even the possible advantage of supreme arrogance, which though it did not work for the 1883 Old Etonians probably helped Epeues? Seeding, records, divisions and trophy cabinets ensure that competing athletes never start on a level playing field. Professional status, sponsorship and training facilities make a real difference to achievement. The ethical paradigms by which we judge acceptable from unacceptable are based on judgements and categorisations that fluctuate all the time. When we compare Phendimetrazine with good old mutton chops are we looking at a difference of kind or a difference of degree?

Julian Walker is an artist, writer, researcher and educator. His latest book "The Roar of the Crowd" is a major new anthology of sports writing that captures the drama, excitement and intrigue of athletic achievement and celebrates the innate urge to compete, to fight, and to test the human body. He is also the author of "The Finishing Touch: Cosmetics Through the Ages" and "How to Cure the Plague and other Curious Remedies".

The Thinking Machine: W Ross Ashby and the Homeostat

The British Library holds the personal archive of W. Ross Ashby - psychiatrist and expert in cybernetics (the study of the control of systems using technology). In this guest post Hallvard Haug, postdoctoral fellow at Birkbeck, University of London, examines the figure of W. Ross Ashby and his key invention the homeostat - a machine capable of adapting itself to the environment. A shorter article on W. Ross Ashby is featured on the British Library Untold Lives blog.

Ross Ashby (1903-1972) was a central figure of the post-war cybernetics movement in the UK, especially due to the popularity of his books Design for a Brain (1952) and  An Introduction to Cybernetics (1956). Ashby kept a thorough record of his thoughts throughout his adult life, and a collection of his papers has been donated to the British Library by his family.

The centrepiece of the collection is Ashby’s notebooks which he kept from 1928 up until the year of his death. Among students of cybernetics these are legendary, and for good reason. Over the course of nearly 50 years, Ashby took meticulous stock of his thoughts on the material nature of the brain, and the notebooks show the workings of a highly systematic and deeply creative mind. Written in a precise hand, the journals brim with insights, speculations, calculations, graphs, drawings, newspaper clippings and circuit diagrams. Ashby also kept a meticulous topical record complete with content pages, cross referencing, summaries of entries, as well as two different sets of indexes — also included in the collection (Add MS 89153/27-30). Eventually, the notebooks ran to 7189 pages and spanned a total of 25 volumes.

At first, the notebooks were a pastime; eventually, however, the ideas Ashby explored became original enough to be publishable and in time these notes became the focus of his working life as his cybernetics work. The most famous of his innovations was the homeostat, a machine which demonstrated and embodied his theory of learning and adaptation in a mechanical apparatus which, entirely on its own, regains stability when perturbed. The development of the homeostat is documented thoroughly in the notebooks, from its first entry on 19 November 1946:

"I have been trying to develope [sic] further principles for my machine to illustrate stability, + to develope ultrastability" (Add MS 89153/9).

In the coming years, it was the centrepiece for his cybernetic activities.

The homeostat — a bulky and somewhat baroque machine built from military surplus parts — had a single purpose: to regain stability in response to perturbations in its environment. It is hard to convey precisely how the homeostat worked: set up as four identical units connected to each other via electrical inputs and outputs, each unit was topped with electrically conducing vanes dipped in water troughs. Like oscillographs, the vanes moved back and forth in the trough, reacting to the electrical input from their environment — the output from other blocks in the setup — and each block had an electrical output determined by the position of the vane in the trough. If the vane was directly in the middle of the trough, the electrical output was zero; if, however, it was positioned any other place in the trough, it provided electrical output to the other blocks, affecting the positions of the vanes it was connected to. Thus, when the machine was set in action by pushing a vane out of position, the vanes on all four units would react by moving back and forth, in reaction to their respective environments.

Image of Ashby’s hand drawn diagram for the final version of the Homeostat from page 2432, Journal 11. (

What made the homeostat so interesting, however, was its ability to return to equilibrium once a vane had been upset. Each of the units was constructed to also produce electric feedback to their respective vanes, depending on the conductivity of the vane. This feedback was determined according to a random table, and the machine would cycle through the table as long as the electrical output was not zero. Eventually, however, the vanes, cycling through random states, would come to a halt as each block found the appropriate feedback configuration. For Ashby, the return to equilibrium that the homeostat demonstrated was equivalent to the brain’s — whether human or animal — capacity for learning. The return to equilibrium demonstrated by the homeostat also showed how what only seems purposeful can come about by randomness, and Ashby believed this principle of feedback mechanisms spontaneously restoring equilibrium was a governing principle in nature. Indeed, in 1945 he noted that he had decided to follow in Darwin’s footsteps: like with the homeostat’s return to equilibrium, he viewed a species’ evolutionary adaptation to its environment as a return to equilibrium, and is only apparently purposeful. This tendency towards what Ashby called ‘ultrastability’ was referred to by Norbert Wiener as no less than ‘one of the great philosophical contributions of the present day.’ Eventually, Ashby was invited to present it at the ninth Macy conference for cybernetics in 1952.

The influence cybernetics exerted on both the sciences and humanities in the 1950s and ’60s was considerable: its central insights touched upon, transformed and occasionally dominated disciplines ranging from computer science, artificial intelligence and genetics through psychology and sociology, and also influenced intellectual movements such as structuralism. Its universal character gained it great popular appeal, but also meant cybernetics never had a comfortable institutional or disciplinary home, with only a few university departments dedicated to it. Despite its popular appeal, Ashby has remained something of an obscure figure. The autobiographical notebook ‘Passing through nature…’ gives a rare insight into his private thoughts, and suggests that it was at least partly due to Ashby’s reticence towards being in the public eye:

"My fear is now that that [sic] I may become conspicuous for a book of mine is in the press. For this sort of success I have no liking. My ambitions are vaguer.

   I am something of an artist, not with pencil or paint, for I have no skill there, but with a deep appreciation of the perfect. […] I have an ambition some day to produce something faultless." (Add MS 89153/33)

Against his inclinations, Ashby set out to spark public interest in his ideas in the 1940s, and for a brief period the homeostat was the topic both of popular magazines and radio shows, promoted as an ‘artificial brain.’ Ashby kept a record of his success, pasting newspaper clippings in the notebooks. The journals are a treasure trove for insight into the trajectory of ideas: from the premature attempts at precisely stating a problem, to the mature implementation, years later, of a successful theory and its subsequent dissemination.

Hallvard Haug is a Wellcome ISSF postdoctoral fellow at the Centre for Medical Humanities at Birkbeck, University of London. His interest in W. Ross Ashby stems from his PhD research on the history of human enhancement technologies, which included a section on cybernetics.

Tunny and Colossus: Donald Michie and Bletchley Park

In honour of British Science Week Jonathan Pledge explores the work of Donald Michie, a code-breaker at Bletchley Park from 1942 to 1945. The Donald Michie papers are held at the British Library.

Donald Michie (1923-2007) was a scientist who made key contributions in the fields of cryptography, mammalian genetics and artificial intelligence (AI).

In 1942, Michie began working at Bletchley Park in Buckinghamshire as a code-breaker under Max H. A. Newman. His role was to decrypt the German Lorenz teleprinter cypher - codenamed ‘Tunny’.

The Tunny machine was attached to a teleprinter and encoded messages via a system of two sets of five rotating wheels, named ‘psi’ and ‘chi’, by the code-breakers. The starting position of the wheels, known as a wheel pattern, was decided by a predetermined code before the operator entered the message. The encryption worked by generating an additional letter, derived from the addition of each letter generated by the psi and chi wheels to each letter of the unencrypted message entered by the operator. The addition worked by using a simple rule represented here as dots and crosses:

• + • = •

x + x = •

• + x = x

x + • = x

Therefore using these rules, M in the teleprinter alphabet, represented as:  • • x x x, added to N: • • x x •, gives • • • • x, the letter T.

In order for messages to be decrypted it was initially necessary to know the position of the encoding wheels before the message was sent. These were initially established by the use of ‘depths’. A depth occurred when the Tunny operator mistakenly repeated the same message with subtle textual differences without first resetting the encoding wheels.

A depth was first intercepted on 30 August 1941 and the encoding text was deciphered by John Tiltman. From this the working details of Tunny were established by the mathematician William Tutte without his ever having seen the machine itself; an astonishing feat. Using Tutte’s deduction the mathematician Alan Turing came up with a system for devising the wheel patterns; known as ‘Turingery’.

Turing, known today for his role in breaking the German navy’s ‘Enigma ‘code, was at the time best known for his 1936 paper ‘On Computable Numbers’ in which he had theorised about a ‘Universal Turing Machine’ which today we would recognise as a computer. Turing’s ideas on ‘intelligent machines’, along with his friendship, were to have a lasting effect on Michie and his future career in AI and robotics. 

Between July and October 1942, all German Tunny messages were decrypted by hand. However changes to the way the cypher was generated meant that finding the wheel setting by hand was no longer feasible. It was again William Tutte who came up with a statistical method for finding the wheels settings and it was the mathematician Max Newman who suggested using a machine for processing the data.

Initially an electronic counter dubbed ‘Heath Robinson’ was used for data processing. However it was not until the engineer Thomas Flowers, designed and built Colossus, the world’s first large scale electronic computer, that wheel patterns and therefore the messages could be decrypted at speed. Michie too, along with Jack Good, played a part, discovering a way of using Colossus to dramatically reduce the processing time for ciphered texts.

The decrypting of Tunny messages was critical in providing the Allies with information on high level German military planning in particular for the Battle of Kursk in 1943 and surrounding preparations for the D-Day invasion of 1944

One of the great ironies is that much of this pioneering and critical work remained a state secret until 1996. It was only through Donald Michie’s tireless campaigning that the General Report on Tunny, written in 1945 by Michie, Jack Good and Geoffrey Timmins, was finally declassified by the British Government; providing proof of the code-breakers collective achievements during the War.

Albert Einstein was a theoretical physicist born in Germany.  He is probably one of the most famous scientists of modern times and his most well-known work, the general theory of relativity, forms the basis of modern physics.  However, after graduating from the Swiss Polytechnic School in Zurich in 19004, Einstein struggled to find a job in academia and so found work as a clerk in the Swiss Federal Patent Office in Bern. He worked here throughout his ‘miracle year’ of 1905, where he was awarded his PhD and also published four groundbreaking papers, and only left in 1909 to accept the post of ‘Professor Extraordinarius’ in theoretical physics at the University of Zurich5.

 

Read some of Einstein's many books at the British Library, ranging from explanations of the Theory of Relativity to autobiographical writings

William HerschelWilhelm_Herschel_03

Friedrich William Herschel was born in Hannover yet moved to Bath, England at age 19.  An accomplished astronomer, Herschel is credited with the discovery of Uranus, the confirmation of the theory that nebulae were composed of stars rather than a luminous fluid, as was the opposing theory, and a theory of stellar evolution6. However, Herschel was only a professional astronomer from the age of 43; until this time, William Herschel taught, performed and composed music and was employed for some time as the organist of a chapel in Bath.

Alexander Graham Bell

Alexander Graham Bell was born in Edinburgh to a family of elocutionists.  Although he is most notably credited with the invention of the telephone,Bell contributed to many other inventions including metal detectors and early aircraft7, and was also a professor of Vocal Physiology and Elocution at Boston University8.  However, as well as his scientific endeavours, Bell was a teacher of his father’s ‘Visible Speech’ system at a number of institutions for deaf or deaf-mute students.  He also opened his own ‘School of Vocal Physiology and Mechanics of Speech’; a notable student being Helen Keller, with whom he worked and was friends for over 30 years9.

Polly Matzinger

Polly Matzinger is an American immunologist and has held research posts at The University of   727px-Polly_&_Annie
Cambridge, The Basel Institute for Immunology and most recently at the National Institute of Allergy and Infectious Disease in Maryland10.  She is most well-known for her work on ‘The Danger Model’, a theory explaining how immune cells can sense when the body is under attack and thus when to mount an immune response.  Leading up to her scientific career however, Matzinger undertook a number of ‘unconventional’ career paths.  Among many jobs, Matzinger worked as a jazz musician, problem dog trainer and even a playboy ‘bunny’, however it was her job as a cocktail waitress and an evening serving two university professors which led to her being persuaded to pursue a career in science11

Alice's Adventures in Numberland

Tonight we are celebrating the science and maths of Lewis Carroll in our Alice's Adventures in Numberland event with geek comedy trio Festival of the Spoken Nerd. As well as being a best-selling children’s author, Lewis Carroll was also a mathematics lecturer at Oxford University and an avid puzzler. He loved musing over word, number and logic problems and sharing them with his friends and colleagues. Special guest geek Katie Steckles has compiled this collection of Carroll-inspired brainteasers for your puzzling pleasure. How many can you complete? Answers can be found in this blog post.

MAZE Knight

Can you find a route from the outside of the maze to the centre?

  Maze

A similar, but more complicated maze like this, created by Carroll in his early twenties, appeared in his family’s homemade puzzle magazine, Mischmasch.

 

DOUBLETS KnightKnight

For each pair of words, can you find a series of words which link them, changing just one letter each time? All links must be real words. As an example, you can get from HEAD to TAIL using four links as follows:

    HEAD

    heal

    teal

    tell

    tall

    TAIL

Drive PIG into STY (4 links)

Make WHEAT into BREAD (6 links)

Raise FOUR to FIVE (6 links)

Prove GRASS to be GREEN (7 links)

Change OAT to RYE (3 links)

Cover EYE with LID (3 links)

Raise ONE to TWO (7 links)

Crown TIGER with ROSES (5 links)

Carroll introduced this type of puzzle, now more commonly known as a Word Ladder, in a letter to Vanity Fair in March 1879, and after initial trials, they began using it as their regular puzzle competition – the examples above are taken from there.

 

DOUBLE ACROSTIC POEM KnightKnightKnight

Each couplet in this poem clues an 8-letter word. If you find all 8 words, their first letters will spell out a word, and their last letters will spell out another word.

The double acrostic is often thought of as the forerunner to the modern crossword puzzle, and Carroll made many contributions to the form. In his collection of poems Phantasmagoria (1869), he published an example in which the stanzas were more connected to form a readable poem, rather than disjointed as in the example above. Another, written by Carroll for Miss E M Argles, was printed in the catalogue for the exhibition in London to commemorate the centenary of Carroll’s birth.

 

AMBIGRAMS Knight

An ambigram is a word or phrase which is written in such a way that it reads the same when rotated, or reflected. Examples of different rotation and reflection ambigrams are given here. Can you devise a rotation ambigram for the word FISH? Or a reflection ambigram for BIRD? Or, you can try to devise one for your own name, or a word of your choice – some words are harder than others! You can use whichever type of letters you like, and add interesting serifs and decorations, as long as it still reads as that word. Sometimes ambigrams read as one word in one direction, and a different (sometimes opposite) word in the other.

In Collingwood’s Life and Letters, Isabel Standen recalls being shown this puzzle by Carroll in 1869.

Memory Matters: The Art and Science of the Brain

Alexander Brown reflects on the recent Memory Matters event in collaboration with UCL Neuroscience.

If I wanted to define ‘Memory Matters: The Art and Science of the Brain’ with a quote, it would be the words of Lewis Carroll’s White Queen in “Alice Through the Looking Glass”: ‘It is a poor sort of memory that only works backwards.’ In short, it was too fine an evening to be terse about.

Memory matters programme
The Memory Matters event programme

In the erudite setting of the British Library, sheltered from familiar London screeches, the event appropriately began with an example of procedural memory, the tango. The passionate and strangely grave dancers were scientist and artist collaborators Nicky Clayton and Clive Wilkins, whose theme was mental time travel. Clive introduced memory as a subjective yet shared experience allowing exploration of the past, prediction of the future, and the envisioning of imaginary worlds. Nicky then spoke of mental time travel in science. The hippocampus, the hub of declarative memory, was introduced, and the consequences of its destruction portrayed through a heartrending video interview of musician and amnesiac Clive Wearing. With only a moment-to-moment consciousness, the absence of the permanent marker of the past abandoned his present to mere thoughts, passing away one by one into oblivion. This man, who had no memory of having eaten, tasted or touched, nevertheless stated: “consciousness has to involve me”. This was followed by the story of a study on caching food in that remarkable bird, the jay. When left in either a ‘breakfast room’ or a ‘hungry room’ over a series of nights, the jay was five times more likely to store food in the ‘hungry room’ the next morning.  This demonstrated the jays ability to plan for the future, bettering small children in that activity.

Clive then spoke on the role of mental time travel for the artist. As Carroll alluded to, humans are the only species that allow time to move in two directions, via thought. This process is coloured by our culture, history, and mistakes.  Sir Frederick Bartlett, experimenting on subjects asked to recall fragments of Canadian Indian folklore, revealed how our memories can rewrite history according to self-serving preconceptions. The Moustachio Quartet, a tetralogy of novels penned by the speaker himself, mines mental time travel for ‘tools in the artist’s toolkit’. The four books can be read in any order, giving the reader power to distort and reinterpret the action of the novels just as our imagination or the order of events might reshape our reality. This phenomenological approach to memory, in which phones and teacups are mere extensions of our being, is both individualistic and also shared, and from it spring the ideas (and prejudices) of society. Memory becomes our social organization. As was discussed following an insightful question from the audience, this collective vision is one of many possible visions, equally as subjective as the individual one, and certainly less sincere.

Interval activities

Three breakout rooms were on show during the interval. The first, ‘Perceptions of Dementia’, hosted by the Alzheimer's Society challenged assumptions. Film and discussion provided the opportunity to step into the shoes of someone with dementia, enduring the difficulty of making a cup of tea and desperation on busy London streets. The second, ‘Forgetting to Fly’, celebrated the fruit fly in modern neuroscience, displaying common tests of locomotion and one using the flies’ moreish tastes for cider vinegar and rotting banana to test its memory. This room was hosted by early career researchers from UCL's Institute of Healthy Ageing. The third, ‘Voices of Science’, provided an online collective, subjective memory of oral histories from past greats from British science and technology.

On returning to the lecture theatre, I Remember Things’ showcased the talents of Chris Rawlins, who, treating memory as a ‘muscle’ to be trained, was able to recall street names and places in London based only on map grid references given to him by members of the audience. He followed this with a demonstration of a memory-improving technique, and some fantastic feats of photographic memory.

Finally Hugo Spiers brought us back ‘from tap dancing to facts’, giving an overview of the ‘abnormal’ brains of London taxi drivers, whose posterior hippocampus swells as they commit London’s many streets to memory. We learnt that the posterior hippocampus is more active the greater its options, such as when stepping out onto a sunlit courtyard without anywhere in particular to go. A very elegant experiment on rats was described, where the rodents were shown rice beyond a barrier in a particular inaccessible location. Following sleep, they tested the frequency at which they later made the correct turning towards the area with the rice, now available. The results showed that rats - quite splendidly - appear to dream of the future, emphasizing the role the past plays in planning ahead. The rat creates a map of the future with echoes of the past, simulating its future journey, like London cabbies, in the hippocampus.

The amnesiac Clive Wearing obsessed over possessing ‘the captured thought’, among the many that forever evaded his consciousness. In Chris Marker’s short film La Jetée, across an oneiric sequence of black-and-white stills, the main character rejects the ‘real’ world in favour of a memory with the woman of his dreams. Without spoiling a wonderful film further, I wondered how different and yet how identical the two wishes were, and how bound we are to memory and identity, which, if not entirely mythological beasts, transcend our reason and science. Making these connections was of course why we all presented ourselves at the doorstep in the first place. I congratulate the British Library, UCL Neuroscience and all involved on a very exciting effort at bridging art and science.

Science in Schools: What are the options?

Here we share some of the highlights from our most recent TalkScience event.

The topic under discussion at the 30th TalkScience event was the future of secondary science education. We welcomed  Ed Dorrell (Times Educational Supplement) to chair a panel of expert speakers including Professor Louise Archer (Kings College London), Peter Finegold (Institution of Mechanical Engineers), and David Perks (East London Science School).

The panel gave a wide-ranging introduction referring to the skills shortage and the economy, science in society, and social justice. These broad issues framed the discussion of more specific points about the nature of the science curriculum (baccalaureate or ‘traditional’ academic science education), CPD for science teachers and the concept of ‘science capital’. The introduction was followed by a lively discussion between the audience and the panel.

Take a look at the highlights video here:
