  This paper is a celebration of the frontiers of science. Goodenough, the
maestro who transformed energy usage and technology through the invention of
the lithium ion battery, opens the programme, reflecting on the ultimate limits
of battery technology. This applied theme continues through the subsequent
pieces on energy related topics (the sodium ion battery and artificial fuels,
by Mansson) and the ultimate challenge for 3 dimensional printing the eventual
production of life, by Atala. A passage by Alexander follows, reflecting on a
related issue: How might an artificially produced human being behave? Next
comes a consideration of consiousness and free will by Allen and Lidstrom.
Further voices and new instruments enter as Bowen, Mauranyapin and Madsen
discuss whether dynamical processes of single molecules might be observed in
their native state. The exploitation of chaos in science and technology,
applications of Bose Einstein condensates and a consideration of the
significance of entropy follow in pieces by Reichl, Rasel and Allen,
respectively. Katsnelson and Koonin then discuss the potential generalisation
of thermodynamic concepts in the context of biological evolution. Entering with
the music of the cosmos, Yasskin discusses whether we might be able to observe
torsion in the geometry of the universe. The crescendo comes with the crisis of
singularities, their nature and whether they can be resolved through quantum
effects, in the composition of Coley. The climax is Krenn, Melvin and Zeilinger
consideration of how computer code can be autonomously surprising and creative.
In a harmonious counterpoint, Yampolskiy concludes that such code is not yet
able to take responsibility for coauthoring a paper.
