Jim Baggott

What does material substance consist of? Jim Baggott, author of Mass: The Quest to Understand Matter from Greek Atoms to Quantum Fields, argues that whilst modern physics has given us ways of dealing with the question, it has not actually provided the answer.

Communicating physics is difficult, partly because the underlying ideas can be hard to grasp, even for experts. Popular science writer, Jim Baggott, talks us through some of his favourite physics books.

Ahead of his talk at the Royal Institution in London, Jim Baggott delved into the nature of mass.

In this short Hay Levels video, Jim Baggott talks about the relationship between matter and mass, the subject of his next book Mass: The Quest to Understand Matter from Greek Atoms to Quantum Fields, to be published by Oxford University Press in June 2017.

Much of the recent debate about string theory and the scientific method derives from the mis-use or mis-interpretation of the word ‘theory’. Scientific theorizing follows a logical progression from idea to hypothesis to theory, and I argue that a fully-fledged scientific theory must be grounded in empirical data. In the absence of empirical data, non-empirical arguments will suffice to choose between rival hypotheses, but they cannot ‘confirm’ theories. A lack of clarity on the status of the ‘string hypothesis’ in many popular presentations has created the misleading impression that this is regarded as a valid and accepted scientific theory, threatening to undermine public trust in science and scientists. A ‘Munich Declaration’, developed by participants at the recent conference ‘Why Trust a Theory’, is proposed as a potential way forward.

The story of human evolution does not end with the appearance of Homo sapiens in Africa 200,000 years ago, or with the subsequent migrations to Europe, Asia and the rest of the world. Our curiosity about our origins demands that we try to explain why it is this particular species that goes on to dominate the planet.

Jim Baggott is an influential science writer. A scientist himself by training, he has turned toward a career in the commercial world and is also a successful author who popularizes complex scientific theories by making them, well, understandable.

His latest, Origins: The Scientific Story of Creation, is a concise history of how we got here, how life has evolved on this planet, and where life may be heading next. Baggott joins us here for an hour. We only wish that we’d had more time.

The evolutionary path from early primates to Homo sapiens is difficult to trace with any accuracy and continues to be hotly debated. But there are a couple of important signposts in the fossil record. The transition to bipedalism – upright walking – is suggested by analysis of limb bones of the genus Australopithecus and rather spectacularly confirmed by the Laetoli footprints, determined to be 3.6 million years old.

Last year Pope Francis declared that ‘Evolutions in nature is not inconsistent with the notion of [divine] creation’. The argument is that, once life had been created, evolution drove it with irresistible force towards us: intelligent human beings.
