To risk sounding like a smart aleck seven-year-old, technically speaking you can only prove things mathematically. If you need to know that one plus one equals two, don’t go to a chemistry lab. The natural sciences deal with objects and forces that can be observed and measured. Scientists look at the evidence from their experiments and try to come up with a way of thinking about the material world that makes sense.
For example, if I travel around my local area and see nothing but brown cows, then I could try out the statement that “all cows are brown”. I couldn’t prove that all cows are brown. I could never rule out the existence of a different-coloured cow somewhere in the world. Scientific knowledge is always provisional. Continue reading →
In the last few weeks, the world has watched as a new burst of seismic activity in Iceland led to a dramatic eruption near the volcano Bardarbunga. Bob White, Professor of Geophysics at Cambridge University, heads up a research team who have been recording earthquakes caused by the massive underground flow of magma. Unusually for a full-time Professor, Bob is also the Director of the Faraday Institute. In this guest post, he describes the wonder of this spectacle and how it relates to his own faith.
We arrived at the eruption site around midnight on 1st September. My team and I were part of just a handful of people allowed into the 10,000 square kilometre exclusion zone – a black volcanic desert 2,000 feet high. The darkness of the night was uninterrupted by any human lights, and we knew there was no-one else Continue reading →
