Career Trajectories Day
What can you do with a Physics degree? Plenty although the reality is that most people being trained in physics at the undergraduate graduate or even postdoctoral levels aren't aware of the broad spectrum of opportunities available to them. The problem solving skills necessary to succeed in physics are sought after in a wide range of technology financial and industrial sectors. This day will bring together current students and postdocs in theoretical physics with former students who have found great success in a wide range of different areas from startups to big companies finance and even bestselling novels. Many of them were affiliated with Perimeter Institute and chose their career paths over opportunities in academia. Through a combination of talks and panel sessions this day will showcase the many career possibilities available to young physicists steps they can take to explore these options and how to avoid the inevitable pitfalls. Lunch will be provided and there will ample opportunities to ask questions and network.

New Directions in Conventional and Ambitwistor String Theories
The goal of the workshop is to foster interaction between researchers working on the Smatrices of conventional strings and on ambitwistor strings. The workshop will exploit synergies between the two frameworks and identify the current key questions in the fields and areas that can benefit from collaboration. The program of the workshop will be tailored to questions and problems raised by the participants in the runup to the event. The goal is to spend most of the time on collaborative discussions in order to exchange expertise and to attempt to resolve questions during the workshop. A list of such problems can be found below and this will be extended by the participants in the runup to the meeting. To obtain ambitwistor integrands and BernCarrascoJohansson (BCJ) numerators for multiloop amplitudes and to connect with superstring worldsheet correlators. To develop fully nonlinear approaches by working on curved backgrounds both for application to AdS/CFT and to problems in perturbative gravity and gauge theory on nontrivial backgrounds. To understand the twistor and ambitwistor geometry underpinning both conventional and ambitwistor strings including the geometry of soft limits infrared structure and its links with formulations at null infinity. To explore mathematical structures behind the integrals of conventional and ambitwistor strings (positive geometries and canonical forms twisted (co)cycle etc.)

Open Research: Rethinking Scientific Collaboration
Scientific inquiry in the 21st century is beset with inefficiencies: a flood of papers not read theories not tested and experiments not repeated; a narrow research agenda driven by a handful of highimpact journals; a publishing industry that turns public funding into private profit; the exclusion of many scientists particularly in developing countries from cuttingedge research; and countless projects that are not completed for lack of skilled collaborators. These are all symptoms of a major communication bottleneck within the scientific community; the channels we rely on to share our ideas and findings especially peerreviewed journal articles and conference proceedings are inadequate to the scale and scope of modern science. The practice of open research doing science on a public platform that facilitates collaboration feedback and the spread of ideas addresses these concerns. Opensource science lowers barriers to entry catalyzing new discoveries. It fosters the realtime sharing of ideas across the globe favoring cooperative endeavor and complementarity of thought rather than wasteful competition. It reduces the influence of publishing monopolies enabling a new credit attribution model based on contributions made rather than references accrued. Overall it democratizes science while creating a new standard of prestige: quality of work instead of quantity of output. This workshop will bring together a diverse group of researchers from fields as diverse as physics biology computer science and sociology committed to opensource science. Together we will review the lessons learnt from various pioneering initiatives such as the Polymath project and Data for Democracy. We will discuss the opportunity to build a new tool similar to the software development platform GitHub to enable online collaborative science. We will consider the challenges associated with the adoption of such a tool by our peers and discuss ways to overcome them. Finally we will sketch a roadmap for the actual development of that tool.

HandsOn Maple Workshop
Generally speaking, physicists still experience that computing with paper and pencil is in most cases simpler than computing with a Computer Algebra System. Although that is true in some cases, the working paradigm is changing: developments in CAS, and particularly recent ones in the Maple system, have resulted in the implementation of most of the mathematical objects and mathematics used in theoretical physics computations, and have dramatically approximated the notation used in the computer to the one used with paper and pencil, diminishing the learning gap and computersyntax distraction to a strict minimum. In this talk, the Physics project at Maplesoft will be presented and the resulting Physics package will be illustrated through simple problems in classical field theory, quantum mechanics and general relativity, and through tackling the computations of some recent Physical Review papers in those areas. In addition to the 10:00 am lecture (taking place in Alice), there will be an afternoon handson workshop taking place from 2:00  5:00 pm in the Time Room.
We recommend that participants for the handson workshop bring their own laptop with a copy of Maple installed. Please contact Erik Schnetter <eschnetter@perimeterinstitute.ca> ahead of time if you cannot do this, and we will try to make other arrangements.
Registration for this event is now closed.
