The increasingly digital records of our communities and our organizations require all of us to become digital stewardship and digital preservation practitioners. The challenge seems daunting but the good news is we don’t have to do it alone. A distributed network of practitioners and learners across the globe are increasingly finding ways to learn together and share and pool their resources to tackle these challenges and provide enduring access to our digital heritage. This talk will provide an overview of key principles for practicing digital stewardship and an orientation to how to connect with and engage with the international community of practice developing and refining the craft of digital stewardship and digital preservation.

Measured by the accuracy of its predictions and the scope of its technological applications, quantum mechanics is one of the most successful theories in science--as well as one of the most misunderstood. The deeper meaning of quantum mechanics remains controversial almost a century after its invention. Providing a way past quantum theory's paradoxes and puzzles, QBism offers a strikingly new interpretation that opens up for the nonspecialist reader the profound implications of quantum mechanics for how we understand and interact with the world. Short for Quantum Bayesianism, QBism adapts many of the conventional features of quantum mechanics in light of a revised understanding of probability. Bayesian probability, unlike the standard "frequentist probability," is defined as a numerical measure of the degree of an observer's belief that a future event will occur or that a particular proposition is true. Bayesianism's advantages over frequentist probability are that it is applicable to singular events, its probability estimates can be updated based on acquisition of new information, and it can effortlessly include frequentist results. But perhaps most important, much of the weirdness associated with quantum theory--the idea that an atom can be in two places at once, or that signals can travel faster than the speed of light, or that Schrodinger's cat can be simultaneously dead and alive--dissolves under the lens of QBism. Using straightforward language without equations, Hans Christian von Baeyer clarifies the meaning of quantum mechanics in a commonsense way that suggests a new approach to physics in general.
By 1 April 1969, John Adams was ready to take up his new role, as Director of CERN’s 300 GeV project, full-time. This photo shows him presenting plans for the new accelerator a few months earlier – you can read the minutes of the 16 January 1969 Committee of Council meeting, largely devoted to discussion of the project, here.
At this time it was not even clear in which country the new machine would be built. By showing that it made most ﬁnancial and technological sense to build the Super Proton Synchrotron next to the existing CERN site, Adams was able to break the deadlock between member states.
