Interested in the connections between art and science? Then come to this free public lecture at the Isaac Newton Institute in Cambridge on March 14, 2012 to hear theoretical physicist David Berman and artist Grenville Davey talk about string theory as an inspiration to art.

String theory is at the cutting edge of theoretical physics. Its deep goal is to unify quantum mechanics and relativity. In doing so, string theory brings up new ways of seeing the world, with hidden dimensions and novel surprising symmetries and relationships. This event will begin with an accessible introduction to string theory by David Berman followed by a presentation and discussion with Grenville Davey on his art and how aspects of string theory and contemporary physics have been an inspiration. A wine reception will follow.

Grenville Davey is a Turner Prize winning sculptor who is currently artist-in-residence at the Institute. His recent interests and work have been inspired by the ideas from string theory and its way of describing our universe. David Berman is currently organising a programme at the Institute on string theory and is an expert in M-theory, an extension of string theory.

To request free tickets to this event please contact the Isaac Newton Institute by phoning +44 (0)1223 335999 or emailing reception@newton.ac.uk. Some tickets will also be available on the night but pre-booking is recommended. This event is likely to be suitable for interested people age 14+. It starts at 6.30pm and lasts for an hour.

Rachel and Marianne at the Vancouver Aquarium

This week saw the opening of the Plus Canada office for the American Association for the Advancement of Science (AAAS) meeting in Vancouver. We were very excited to join the other 8000 delegates, speakers, journalists and exhibitors at the opening ceremony on Thursday evening. After a traditional welcome from Chief Jacob and his niece, from one of the First Nations local to Vancouver, Nina Federoff, President of the AAAS, told us her story in science. And it was quite a story: from taking college classes at 16, dropping out of school and having her first child at 17, she struggled her way through university as a single mother to finally become a world-renowned geneticist and molecular biologist.

We also heard from a number of other speakers, including our old friend Neil Turok, previously at the Centre for Theoretical Cosmology at the University of Cambridge but now Director of the Perimeter Institute here in Canada. Turok said that science and education will give us the tools to solve the problems facing the world today. And he suggested a new slogan for the meeting, "Seven billion minds", saying that the young people on the planet are our greatest resource and with our help will tackle these problems in the future.

Our first day was rounded off by a lovely dinner with jelly fish and dolphins at the Vancouver Aquarium. We met up with some of the other journalists from around the world, including visitors from Australia, Germany and Finland. You can listen to a quick podcast of our thoughts from the first day here.

Friday started bright and early with a Press Breakfast about Canada's relationship with the oceans and Arctic. Sherilee Harper from the University of Guelph is studying the relationship between weather, water and health and told us how climate change was already affecting the indigenous populations of Canada. For example, many people in these communities prefer to drink fresh brook water than treated water out of the tap. However her studies have revealed that bacterial levels in these streams increase sharply after heavy rains, which can be directly linked to increased clinic visits in the local communities for gastrointestinal illness in the weeks that follow.

We spoke to another of the panel members, Marcel Babin from the Université Laval, who uses satellite images to monitor the biodiversity in the Arctic ocean. His team also conduct experiments in the lab of how algal growth is affected by changing light levels. The mathematical models they produce can then feed into predictive models of how changing sea ice levels in the Arctic will affect biodiversity, and how this changing biodiversity will itself impact on climate change. You can listen to the podcast of our interview here.

Later on in the day we stayed with biomass, this time the 100 billion tons of it produced annually by plants through photosynthesis. Greg Scholes from the University of Toronto has been studying how plants do it. In his experiments he found that delicate quantum effects, which people didn't think could survive very long in the real world, played an important role in photosynthesis, a discovery which may opens the way for the new field of quantum biology. You can read our article of Scholes' work here.

And of course this was only a handful of the myriad of topics on offer on Friday. We also managed to catch a session on how topology is saving the day when it comes to analysing large datasets, particularly in biology. And we caught up with the latest news from CERN and Fermilab: they should have definitive evidence of the existence or non-existence of the Higgs by the end of the year (you can read more on the Higgs Boson and the LHC here), and experiments to try to replicate the faster-than-light neutrino results from the OPERA experiment are already under way with results expected this Summer.

Rachel with John Harvard!

Dear Plus in Cambridge (UK) and lovely Plus readers,

Well I'm all packed, checked out and ready to head home. It's been a great trip but I am looking forward to getting back to a place where I understand the road rules (I alternate between nearly being run over or not realising the reason a car has stopped is because it is patiently waiting for me to cross the road) and where I can get a nice cup of Earl Grey. Here's my highlights from the last couple of days...

I had a great time with Mboyo Esole, a lecturer in the maths and physics departments at Harvard. Esole patiently attempted to explain elliptic curves, elliptic fibrations and the geometry of string theory to me over a delicious lunch at a local Indian buffet. Salt shakers and table tops took on a life of their own as they stood in for higher dimensional spaces and singularities! It was really inspiring to hear him enthuse about the beauty of his field and how inspiration from the world of physics can lead mathematicians to discover unchartered areas of the world of maths.


Esole also showed me around the maths and physics departments. Highlights included:

Mboyo Esole outside the Jefferson Lab
  • Spotting Harvard chairs
  • Meeting his colleagues at the Center for the Fundamental Laws of Nature, including Andy Strominger, who we spoke to at Hawking's 70th birthday conference last week.
  • Climbing up to the top of a tower in the Jefferson Physical Laboratory – now it has a comfortable seating area and a great view over Harvard but originally it was used for ingenious experiments.
  • Seeing Mboyo's favourite tree, just outside the Jefferson Lab – it bursts into flower overnight each Spring!

Last night I headed into Boston on the Number 1 Bus, which not only goes past MIT but also past Fraternity houses named things like Alpha Delta Phi – just like in the movies! And it also takes you to Northeastern University, home of Laszlo Barabasi's Center for Complex Network Research. It was great to meet some of the researchers there and to sit in on a Network Science class. Then Barabasi explained the new perspective network science is bringing to a huge variety of areas - from understanding the world wide web to new strategies to tackle AIDS. Far from being just of theoretical interest, he says that "understanding the network gives you actionable principles you can use in the field". Stay tuned for the upcoming article!

See you all soon!

Dear Plus in Cambridge (UK) and lovely Plus readers,

The weather here is lovely - cold enough to freeze your nose off but beautiful and sunny. Now that we have got the usual postcard chat out of the way, here are some highlights from my first couple of days here...

View from hotel window
  • Rare events really do happen – I got upgraded on the flight over!
  • The best view out of a hotel window is definitely airplanes messing about.
  • It is possible to walk from the Harvard Square T station to my B&B entirely on the sunny side of the street (an underappreciated variant of the travelling salesman problem).
  • Martin Nowak's work on evolutionary dynamics proves, yet again, that maths in the language of the Universe. Maths is now an integral part in the study of evolution, describing how mutation and natural selection affects a reproducing population. And now maths has shown that it if you want to get ahead in the evolutionary race, it really does pay to be nice. Nowak said in our interview today: "Whenever evolution wants to achieve a creative new solution, a macrostep in evolution, such as multicellular organisms or language, evolution needs cooperation." It was great to talk to him and it should make for a fascinating article!

Wish you were all here,

Plus in (the other) Cambridge

P.S. It really is very cold here. But they do have very good cupcakes. So it all evens out in the end...

What events should an ambitious nation target as the "easiest" in which to win Olympic medals? How does Olympic success correlate with a nation's GNP? How does the location of the Olympics affect the chance of record breaking? How can simple statistics help us understand the likelihood of winning streaks and the chance that an innocent athlete will fail a drugs test?

John D. Barrow, mathematician, cosmologist, and best-selling author, will explore these question and more in a free public lecture at Gresham College in London tomorrow, 17th January 2012. It's part of a maths and sport series — see the Gresham College website for recordings of past maths and sport lectures and details about upcoming ones.

Tomorrow's talk is at 1pm at the Museum of London, London Wall, London EC2Y 5HN.
