We frequently affiliate a feeling of splendor with paintings or model layout, poetry or dance, however the notion of attractiveness is unusually vital in technology besides. using the time period is such a lot obvious within the "elegant proofs" of mathematics--which Bertrand Russell as soon as defined as "capable of a stern perfection resembling merely the best paintings can show"--but as Ian Glynn unearths during this attention-grabbing new publication, the belief of attractiveness is key to scientists operating in all fields.

Glynn attracts on quite a lot of examples that show the attractiveness of technology, from Pythagoras' theorem and Archimedes' evidence to Kepler's legislation, the experiments that proven the character of warmth, and the different remarkable episodes that ended in Watson and Crick's discovery of the constitution of DNA. Scientists usually percentage a feeling of admiration and pleasure on listening to of a chic method to an issue, a chic conception, or a sublime scan. For scientists, as for artists, beauty implies attractiveness, simplicity, readability, and share; the stylish answer has one of those beautiful and unalterable rightness that evokes ask yourself and awe. the belief of splendor could appear unusual in a self-discipline that prides itself on objectivity, yet provided that technological know-how is considered a lifeless task of counting and measuring. it's, in fact, way over that, and Glynn exhibits accurately how and why beauty is a basic element of the sweetness and mind's eye taken with clinical task. a sublime resolution would possibly not continually be an accurate one, Glynn cautions, yet beauty is deeply concerning vital philosophical problems with inference and most sensible rationalization.

Written with a similar readability and stylish simplicity it describes, Elegance in Science explores a frequently forgotten yet profoundly very important point of medical discovery.

Example text

One of his most successful methods of measurement was to take advantage of human sensibility to any deviation from a regular rhythm. If you are listening to regular beats half a second apart, nearly everyone can detect an 1 error if one beat is just 32 of a second too early or too late. What Galileo (a lute player himself) did was to tie loops of catgut at intervals round the wooden slope—rather like the gut frets tied round the neck of a lute. To set the initial position of the loops he released the ball in time with the beat of a tune with a strong rhythm, and marked roughly the position of the ball at each subsequent beat.

But if the Earth’s surface were moving at such speeds, you might expect that anything not attached to it (such as an apple falling from a tree, or a stone thrown upwards into the air) would rapidly be left behind. Before Galileo, the standard way of dealing with this kind of objection was to refer to the kind of thought experiment suggested by the English astronomer Thomas Digges, who in 1576 had pointed out that a stone dropped from the mast of a fast moving ship lands at the base of the mast, not further back.

We are all familiar with some version of the story of Newton’s apple, but to appreciate what Newton did we need to know the intellectual situation he faced. And to do that we need to look at the extraordinary way in which ideas about the Universe, which had remained almost static from the time of Ptolemy (second century ad) to the early sixteenth century, were developed by four remarkable, fascinating, and very different men over the next century and a half. The four men were Nicolaus Copernicus (a Pole), Johannes Kepler (a German), Tycho Brahe (a Dane), and Galileo Galilei (an Italian), and it is their work that provided the foundation for Newton’s achievements in this area, and that also, incidentally, provides interesting examples of elegant and not-so-elegant science.
