How useful is mathematical modelling in biology? Given the complexity of genetic and cellular processes across multiple organizational length scales, biology has eluded a rounded description in terms of a handful of fundamental equations. But there is compelling evidence that this intricacy masks elegant underlying structure: the nominal information content of (coding) DNA, the plasticity of early cell identity, and the adaptive immune system.
In this event, we investigate the state-of-the-art for using our ever-increasing mathematical toolbox to describe and predict biological processes with comparatively simple models. Mark Kotter, a stem cell biologist and founder & CEO of Bit Bio, discusses a unique opportunity to systematically interrogate the OS of human cell programming. Physicist and LIMS Fellow Ton Coolen describes mathematical models of gene regulation and epigenetic programming. Physicist and LIMS postdoc Alexander Mozeika talks about the statistical physics of the adaptive immune response and high-dimensional statistical inference. LIMS director and physicist Thomas Fink describes theoretical approaches to understanding the dynamics of network motifs and larger regulatory networks. This is followed by discussion on whether we have reached a tipping point where the mathematical sciences can help unleash fundamental insights into the operating system of life.

Scientists discuss the potential of mathematical modelling in biology across problems in cell programming, immunology and gene regulation.

Collective human behaviour describes emergent behaviour when individuals are influenced by the group to which they belong. The focus is often on behaviour that violates laws and social norms. This can range from the innocuous, such as fashion fads, to more serious instances, such as an anomalous voting or disproportionate responses to stress. For instance, it is now widely believed that Cambridge Analytica influenced both the US and UK democratic processes. In an era of social media storms and political demagoguery, understanding the workings of group dynamics, which can be hard to predict, has become increasingly urgent.
In this event, physicist Gioia Boschi from Kings College London explores opinion dynamics with emergent collective memory; physicist Carmen Cabrera Arnau from University College London discusses the dynamics of road accidents in urban areas; and mathematician Zahra Jafari from University College London talks about migration flows. After the talks, there is a general discussion on the scope for turning collective human behaviour into a quantitative science. Everyone is welcome.

Mathematicians and social scientists discuss quantitative models of group dynamics and emergent behaviour on 30 Jan from 6:30. All welcome.

How we go about solving a problem depends on how far into the future it is. When the problem is around the corner, we tend to react to it. But when it’s a long time away, we seek to transform it, putting to use new opportunities that arise in the interim. In other words, on short timescales we act as if our landscape is fixed, but on long timescales we try to shape our landscape so as to allay the concern. Understanding how to balance these strategies can help us manage distant threats, such as man-made and environmental catastrophes. When multiple people act together to shape the future with the right dynamical rules in place, the path to innovative solutions can be fast-forwarded – even in the absence of explicit cooperation. We call this process collective innovation.
In this dinner hosted by the BCG Henderson Institute, we discuss strategies for acting on multiple timescales, how to respond to distant threats and collective imagination. Participants include Brian Arthur, Thomas Fink, Simon Levin, Dan Levinthal, Mihnea Moldoveanu, Michael Nielsen and Martin Reeves, as well as industry practitioners.

Advanced machine learning algorithms provide a powerful set of tools for solving important real-world problems. As machine learning technology improves, these algorithms are becoming responsible for ever more critical decisions. But when they fail in unexpected ways, the consequences can be devastating and potentially lead to cascading failure. 
In this talk, Marc Warner, the CEO and cofounder of AI research company Faculty, talks about how we should manage AI safety both individually and on a collective scale. Clearing a path through the vacuous bullshit that the future of AI tends to accumulate, his conclusions are grounded in Faculty’s scientific research to make AI safe now and in the future. The talk is followed by a general discussion on how to ensure that AI and automated decision-making will be a net positive for businesses and society.

The collective action problem describes a public good for which the benefits cannot be excluded to those who don’t contribute to it. When the benefits of the good are only realised by the next generation, as is the case with fighting climate change, the problem is compounded by the difficulties of long-term forecasting. But the situation is even more complex, because human innovation, which takes place in an expanding space of technological building blocks, is inherently hard to describe, much less predict.
In this dinner at the London Institute, we discuss innovation, technological change and new ways to combat climate change. Physicist and London Institute director Thomas Fink discusses speeding up innovation as an alternative to our current focus on environmental preservation. Technology expert and complex systems founder Doyne Farmer talks about how empirical regularities over past technological change can foretell the rate of change in the future. Building on these ideas, National Medal of Science winner Simon Levin discusses the collective action problem in climate change and how to overcome it.

Tatratea: a Slovakian tea-based liqueur. Ghorme sabzi: an Iranian kidney bean stew. Spaghetti alla puttanesca: Italian pasta with anchovies, olives and capers. These are some of the delicacies, each particular to their country of origin, contributed by everyone who attended the London Institute’s Christmas Party. Thomas Fink kept things real by grilling Texan cheeseburgers in the fireplace, followed by Antonia Tingey toasting marshmallows over a wood fire. 
After the feasting, a Meccano cracker construction competition ensued, which was won by Ton Coolen. Festivities continued into the small hours with drinks and conversation in equal measure.

Companies are composed of many individual employees that are collectively more than the sum of their parts. This super-additive aspect of companies can be thought of as a kind of organizational intelligence. Business leaders strive to build firms which are not only intelligent but can learn—and forget—new things as their goals and environments change. How do companies learn collectively and transform learning into action? How do they learn and act on multiple timescales simultaneously?
In this dinner hosted by the BCG Henderson Institute, we discuss different aspects of intelligent organizations. Martin Reeves, Global Director at Boston Consulting Group and Director of the BCG Henderson Institute, discusses commitment and flexibility in strategy for companies and natural systems. Simon Levin, Professor in Ecology and Evolutionary Biology at Princeton, talks about how "multi-clock" speed organizations act on multiple timescales. Mihnea Moldoveanu, Vice Dean of the University of Toronto School of Management, discusses learning and forgetting in the age of artificial intelligence.

Fires at the London Institute are a regular tradition. They form a focal point for conversation and a backdrop for blackboard calculations. Visitors are delighted and surprised to find a smouldering fire in London, but fires are perfectly permissible. Our fires are made from a range of fuels: hard and soft wood and coal and smokeless coal. (This is in contrast to the American tradition, where resinous soft woods are proscribed because fireplaces are rarely swept). The energy output of these fuels is largely proportional to their densities, but they differ in how much flame they emit and how long they last. In general, soft wood is to hard wood is to coal is to smokeless coal, where the amount of flame decreases along the progression but longevity increases.
The fireplace itself is in the seminar room and dates from the 18th-century. At the top of the marble surround is a classical lamp, in the manner of Robert Adam, which forms the Institute’s seal. In addition to fires for warmth and companionship throughout the year, the fireplace is occasionally used for barbeques—an even rarer central London sight.

An ecosystem is a community of species in a single habitat. Interdependencies within the ecosystem mean the fate of one species can have surprising effects on the ecosystem as a whole. In a similar way, interconnected firms make up an economic ecosystem, and many of the challenges facing it are analogous to those confronting the natural ecosystem. Examples include resilience in the face of unexpected events, the agility to handle sudden environmental change, and the risk of cascading failure leading to ecosystem collapse.
In this dinner at the London Institute, we discuss the application of biological principles to problems in business and the environment. National Academy of Sciences biologist Simon Levin talks about evolutionary strategies for tackling intractable challenges in climate change. Former Government Chief Scientific Adviser Sir John Beddington discusses lessons from ecology on mitigating risk in complex ecosystems. Shifting to current events, New York Times columnist and Pulitzer Prize winner Thomas Friedman discusses reinventing the political process using evolutionary principles.

A blockchain is a way to store a list of records that grows in time in a way that is difficult to falsify. The main idea is that each new record, along with its parent record’s codeword, is translated into a new codeword. Because it is infeasible to decipher a codeword, a record can’t be changed without changing all of the records that have descended from it. In cryptocurrencies based on blockchain, transactions are validated through a process called mining, which is incentivized with rewards to reduce transaction costs. Cryptocurrencies are the best-known applications of blockchain, but are there other uses for commerce and private data that could be just as transformative?
In this event, cryptographer and hedge fund manager Robert Sams talks about cryptocurrency stabilization; Simone Bronzini, co-founder of the blockchain company Chainside, discusses a threat model of blockchain applications; and physicist Andrea Baronchelli from London City University talks about modelling the cryptocurrency market. After the talks there is a general discussion on using blockchain technology for the public good.

Scientists and businessmen discuss the use of blockchain technologies across cryptocurrencies, commerce and the analysis of private data.

The future of blockchain

In one of the most damaging cyberattacks ever, the 2017 Wannacry ransomware spread across 150 countries. By encrypting sensitive data and demanding payment in Bitcoin, it held thousands of businesses hostage. Until it was brought down by a hidden kill switch, the identity of the hostage takers was protected by the blockchain technology behind the Bitcoin cryptocurrency. More crippling ransomware attacks are sure to follow. But how does ransomware work, and how can we protect against it? What is the blockchain technology behind the cryptocurrencies funding it, and how can it transform business? 
In this symposia organized by Elli Streit and Ben Lynch from the LIMS Ventures board, leaders in intelligence, defence, business and academia help answer these questions. Ben Addis from the Serious Organised Crime Agency opens with an introduction to ransomware. Charly Shugg and Jeff Birnbach from Sylint give a strategic vision for cybersecurity. Simone Bronzini, co-founder of Chainside, introduces blockchain and cryptocurrency. Last, Nicolas Courtois from UCL talks about stealth and anonymity in blockchains.

Artificial neural networks were inspired by simple models of computation in the brain. Despite rapid progress in understanding them theoretically, artificial neural networks did not live up to their early promise in terms of practical results. Only recently have they begun to show potential for performing seemingly intelligent tasks. On the other hand, biological neural networks are capable of extraordinary computational feats, but how they achieve it remains a mystery. Do artificial networks really offer insight into brain function, or are they a distinct framework for computation in their own right?
In this event, Thomas Parr from University College London talks about active inference and computational neuropsychology. Grace Lindsay, also from UCL, discusses using convolutional neural networks to study biological visual attention. Alexander Mozeika from King’s College London talks about the statistical physics of feedforward Boolean networks. After the talks there is a general discussion on whether and how artificial neural networks can help us understand the workings of their biological counterparts.

Scientists discuss different types of modified gravity and prospects for a consistent theory in our Late Night at London Institute series.

Modified gravity and cosmology

One of the most puzzling things about physics is that the mathematics that describes the universe is surprisingly beautiful. This language of the universe advances in a way that is both deeper and more elegant then would seem humanly reasonable, despite being borne of human consciousness. As Roger Penrose explains it, “We have a closed circle of consistency here: the laws of physics produce complex systems, and these complex systems lead to consciousness, which then produces mathematics, which can then encode in a succinct and inspiring way the very underlying laws of physics that gave rise to it.” Because the subjects are so intertwined, a guiding principle of the London Institute is to keep them both under one roof.
In this talk Charles Epstein talks about the fruitful but factious relationship between physics and mathematics from the 17th century until now. He discusses the difficulties met when physicists and mathematicians collaborate, the role of intuition in each subject, and how they interpret the concept of “proof”. He speculates on how the two fields will influence each other into the future.

Charles Epstein talks about the longstanding fractious but fruitful relationship between pure mathematics and mathematical physics.

Pure mathematics meets  mathematical physics

How do you describe the behaviour of hair? Leonardo da Vinci thought it flowed like water, but modeling realistic hair in computer animated films is challenging. Hair fibers are elastic filaments with random intrinsic curvature, like cotton and fiberglass. A bundle of fibers is subject to the combined effects of bending elasticity, gravity and orientational disorder. Despite the ubiquity of fiber bundles in the natural and man-made world, a mathematical description of how a bundle behaves has remained elusive.
In this talk Robin Ball develops a mathematical model of the behaviour of a bundle of fibers and applies this formalism to the iconic problem of the ponytail. The elasticity, gravity, and disorder are recast as a differential equation for the envelope of the ponytail bundle, in which the compressibility enters through an equation of state. From this, it is possible to identify the balance of forces in various regions of the ponytail, extract a remarkably simple equation of state from laboratory measurements of real ponytails, and relate the pressure to the random curvatures of individual fibers.

Robin Ball talks about a theoretical model of fibers in which their elasticity and curliness produce the characteristic shape of a ponytail.

Ponytail physics

Technology changes through an evolutionary process in the sense that it satisfies Darwin and Wallace’s key properties: descent with modification and selection. However, the process through which change takes place in technology is very different from that in biology. For example, biology mutates in all directions, but in technology variation is more directed. There are also differences is the available data and our knowledge of it. In biology we have an accurate phylogeny, and the fossil record indicates how this changed through time. For technology we have historical observations of when inventions appeared, but know much less about the forces that influenced them. There are several taxonomies provided by patent processes but they are far from concordant.
There are nonetheless some statistical laws about technological performance, such as Wright’s law and a variety of Moore’s laws for different technology sectors. In this talk Doyne Farmer summarizes the state of the art of our understanding of technological evolution and sketches some of the problems that need to be solved to create a better theory.

Doyne Farmer talks about what technology is and how it evolves and our improving ability to forecast technological change into the future.

A multifractal is a generalization of a fractal in which there is not a single scaling exponent but a continuous spectrum of exponents which depends on the length scale. Multifractals were originally conceived to describe turbulence in fluids, but have since developed into one of the main tools of econophysics. A collection of related studies, econophysics employs statistical physics to investigate the distribution of financial returns, macroscopic models of financial markets, agent-based models of the economy and the network structure of financial institutions.
In this talk Tiziana Di Matteo describes the use of multifractals to study financial data. Two main elements define the complexity of financial time series: multifractality, which is associated with the behavior of each variable and how it scales in time; and the structure of dependencies between time series, associated with the collective behavior of the whole set of variables. So far, these two manifestations of complexity have been investigated separately. Here, by considering both simultaneously, a theory emerges describing how they relate.

Tiziana Di Matteo talks about the interdependence of multifractal financial time series and a new way to understand and forecast them.

One new thing often leads to another. Such correlated novelties are a familiar part of daily life. They are also thought to be fundamental to the evolution of biological systems, human society and technology. By opening new possibilities, one novelty can pave the way for others in a process that Kauffman has called “expanding the adjacent possible”. However, correlated novelties and how they change over time have yet to be quantified empirically or modeled mathematically. Nowadays, thanks to the availability of extensive longitudinal records of human activity online, it has become possible to test whether everyday novelties crop up by chance alone, or whether one truly does pave the way for another.
In this talk Vittorio Loreto proposes a simple mathematical framework that mimics the process of exploring a physical, biological or conceptual space that enlarges whenever a novelty occurs. He tests the predictions on four data sets of human activity. He also highlights future directions: the interplay between individual and collective effects and the different mechanisms supposedly leading to innovation.

BBC science presenter Steve Mould bought a 50m long chain as a prop and stored it in a jar. To his surprise, he found that if he dangled the end of the chain over the rim of the jar, the entire chain would spontaneously flow down to a pile on the floor. More surprisingly, it leapt up in a sustained arc above the jar. Mould made a video of his chain which went viral on YouTube. But despite millions of views and much speculation in illustrious physics departments around the world, no one could explain why the chain rises above the jar.
In this talk, John Biggins explains how he and Mark Warner solved the mystery of the leaping chain. To do so, he first revisits and repairs textbook notions about how chains are picked up from surfaces. He shows that a chain fountain spontaneously forms in the shape of an upside-down catenary, that is, the inversion of the shape of a hanging chain. This is the optimal shape for an arch of perfect compression and has been used by architects and engineers from Hooke and Wren to Gaudi. But the chain fountain is a new structure: an arch of perfect tension stabilized by motion.

Is physics creative? Many people think of it as the opposite: all left brain and no right brain. But when it comes to scientific discoveries, mathematical prowess is only one side of the coin. Fundamental advances rely on finding links, usually mathematical in form, between seemingly disconnected fields—an intrinsically creative act.
In this talk, Thomas Fink gives a personal account of how physicists discovery theories by building systems of the world. He presents three tales from his own experience: about discovering tie knots, tiling the plane and learning to dance. In the first, he explains how systems can be found almost everywhere, if we look closely enough: mathematical structure lurks behind the ordinary as well as the remarkable. In the second, he illustrates how in the world of systems, miracles can happen: our intuition is all but useless when it comes to how the universe works, and there are extraordinary surprises to be had. In the third, he describes the dangers of trying to systematize human aspects of life that resist mathematical insight: not everything has a system, and that’s OK.

Thomas Fink talks about physicists’ inner drive to systematize the world around them and the role of imagination in building theories.

Can mathematics help us understand the market? Consider this real-life conundrum. The El Farol bar in Sante Fe organizes Irish music once a week. It’s a popular event but sometimes leads to overcrowding, which is unpleasant. So in order to decide whether or not to go, each individual tries to forecast the decisions of others, and then do the opposite of the majority: go when most plan to stay home, and vice versa. Deductive reasoning is ruled out, because it would be picked up by others and invalidate itself. In practice, each individual bases his decision on a number of personal ad hoc rules, based on the past performance of himself and others.
In this talk, Anthonius Coolen explains how the minority game—a simple mathematical model of the El Farol bar problem—has increased our understanding of the cooperation and fluctuations observed in financial markets. The minority game exhibits intriguing collective phenomena that would not emerge in game-theoretic market models. Despite its apparent simplicity, it has stumped physicists around the world, and only recently have its several surprises been unlocked.

Anthonius Coolen talks about a game of motorways, bars and financial markets solved by the statistical mechanics of disordered systems.

The Minority Game

A fractal has the property that any part of it, when magnified, resembles the whole. Examples include the snowflake-like Koch curve and the Mandelbrot set. Remarkably, biology employs fractal designs to achieve high efficiency: spongy bone for anisotropic stiffness; ramified networks for gas exchange; and self-similar shells for pressure resistance. But in the man-made world, the reverse is true: fractal designs are rarely used for mechanical efficiency. Transmission towers and the branching columns of Gaudi’s cathedral Sagrada Familia hint at fractal design principles; but the small number of hierarchical levels and the lack of quantitative understanding suggest these are heuristic.
In this talk, Rob Farr explains how new classes of structures based on fractal designs can offer extraordinary gains in mechanical efficiency. Remarkably, they exhibit new strength-to-mass scaling behaviour, where the advantage achieved at one generation is passed on to the next. This bold shift in design philosophy offers a broad range of applications not only in the built environment but also in aerospace and space.

Rob Farr talks about the physics of architecture and how self-similar mechanical structures can make seemingly impossible designs a reality.

In the run-up to the 2008 financial crisis, an increasingly elaborate set of financial instruments emerged, intended to optimize returns to individual institutions with seemingly minimal risk. Little attention was given to their possible effects on the stability of the system as a whole, and the tools available to detect latent stress were qualitative and unsophisticated.
In this symposium for physicists, bankers and policy advisors, we explore the interplay between complexity and stability in deliberately simplified models of financial and trade networks. We draw on analogies with the dynamics of ecological food webs, the spread of infectious diseases and combinatorial models of production. Luciano Pietronero, Fellow of the London Institute and Director of the Institute for Complex Systems, talks about the building blocks of economic complexity and the forecasting of financial crises. Lord May of Oxford, former Government Chief Scientific Adviser and recently President of the Royal Society, discusses his work on systemic risk in banking ecosystems, reported in this week’s cover article in Nature.
