Book Preview: Science and Humanity – reconfiguring the public understanding of science

It is time to shake off a widely believed but mistaken idea of what science is and how it interacts with human life in the round.

For a long time now it has been the habit of science writers to present their discipline as if it was the be-all and end-all of knowledge, and everything else follows in its wake. Particle physicists have written about their forthcoming ‘theory of everything’ as if it amounted to the final word on the nature of reality, the very ‘mind of God’…The same fundamental error is promoted by neuroscientists who, waxing lyrical over wonderful magnetic images of the living human brain, have declared or implied that all the functioning of the brain is about to be laid open, with no input from the arts and humanities required.  Continue reading

Randomness Keeps You Breathing: A physicist’s perspective on the richness of the created order


People love order. Whether it involves a garden, a filing system, or an alphabetical bookshelf, we often get a sense of satisfaction from a good tidying-up job. If you’re thinking “That description doesn’t fit me”, I bet there is at least one area of your life where you are geekily, control-freakily, organised. What about your hard drive, the ‘filing system’ that only you understand which extends off your desk onto the floor and any other available surface in the room, or even aspects of the way you store things away in your memory?

Perhaps this love of structure is why Christians tend to see randomness in nature as a bad thing. Continue reading

Wishing away the Higgs Boson – Reflections of a PhD Student

This post is the result of an interview with Anna Walker, a PhD student in Physics at University of Wisconsin-Madison. It’s interesting to hear the thoughts of someone at the very beginning of their career in science, and to see some familiar themes emerging.

A lot of people come into grad school thinking they’ve got everything figured out, but by the end of the first year you realise that you know nothing. I think it ought to be that way, especially in a field like physics.  I can make predictions and I can do experiments, but in the end I have to be humble about what I actually know. There’s a sense of awe that hits me when I read through a paper or textbook and learn about the way the world works. I try to keep my eyes open so I can see ways in which the physics that I’m studying is actually bringing glory to God. If I’m jaded it’s very easy for me to lose that sense of childlike wonder at the universe and dismiss what I’m seeing as simply mechanistic.

I’m studying the interaction of atoms with each other and with light. The ultimate aim is to make measurements in different technological applications. For example, one of my fellow students is attempting to detect a foetal heartbeat by using atoms to measure changes in magnetic fields. I am developing a system that uses a tiny volume of rubidium vapour, the atoms of which are aligned and controlled with a laser in order to detect changes in magnetic fields. It’s precise and time-consuming work, but I really like tinkering with things and working with my hands. At the moment I’m trying to create the right sort of magnetic field. It’s interesting because I’ve come up against several brick walls where I can’t seem to go any further. With all the circuits I’ve built before it’s been fairly well known how to deal with the problems, so it’s been exciting to go through the process of starting from the basics. In principle what I want to do should be possible, so it’s a matter of finding the best way to do it.

Of course physicists will recognise that we don’t know very much about the way the world is, but I find that a lot of them don’t think about that on a day-to-day basis. They’re thinking more along the lines of how much they actually do know. Scientists are always trying to get to that next level of understanding of the universe, and they think that if we go just one more step further we’ll understand why everything is the way it is. I find that ironic. At the beginning of the last century, physicists thought they had everything figured out – but it was just the tip of the iceberg. The quantum mechanical revolution came along and changed everything. Now I think we’ve pushed the boundaries as far as we can with what we know, and there’s probably going to be another revolution of the quantum mechanical sort that will blow our minds and we’ll realise that we really had no idea what was going on. Take the Large Hadron Collider. I’m sure that part of every physicist wants there to be no Higgs Boson [the particle that the LHC is hoped will discover]. Either this particle has to be there or we have to revolutionise everything we know about physics. It would be exciting to witness that revolution.

Science is culture

A few weeks ago I heard writer Andy Crouch speak at the Everything Conference. His three talks on creating culture are well worth a listen. Andy’s premise is that Christians spend far too long either critiquing culture or simply going along with what is produced by others. We should be cultivating the good that is present in wider culture and creating our own cultures – not in a ‘head-in-the-sand Christian subculture way, but in a way that speaks to the whole of society. I was particularly struck by his talk on creating culture together. Some of the best projects start with two or three people around the kitchen table and expand as they bring others on board. It’s not about the genius alone in their study (though I’m sure lone geniuses – genii? – have their place).

New cultures can take time to develop. Andy quoted Patrick Shaw: ‘We greatly overestimate what we can do in one year, and underestimate what we can do in ten years’. A prime example is the growth of Christianity. On a global scale the resurrection of Jesus Christ had a minimal impact to begin with, but as churches were established and the effects on people’s lives became apparent, Christianity spread so rapidly that within a few hundred years entire nations called themselves Christian.

Of course science both operates within and impacts culture, and all of the above is extremely relevant to scientists, as Andy Crouch knows because he is married to one! Catherine Crouch is a physicist based at Swarthmore College who works on microphotoluminescence and is currently engaged on a sabbatical project studying curvature in cell membranes.

Catherine has written a ‘meditation on light’ that draws on her own work in physics as well as her Christian faith. It communicates beautifully the process of discovery leading to worship. Science clearly contributes to the creation of culture: new discoveries lead to deeper knowledge about the way the world works and helps us to develop new technologies. But, as Catherine so clearly describes, science also shapes other aspects of culture in subtle yet far-reaching ways: a deeper understanding of the world around us impacts the way we see the world and what we believe in.
