Since there have been many controversies over balltampering in international cricket, the subject of how a ball is made to swing has been of considerable interest. To give a clearer understanding of the swingbowling phenomenon, I have transcribed a section from The Art of Cricket by Sir Donald Bradman, who was the most prolific batsman of all time. Pages 12 contain thoughts by The Don on the subject, and Pages 34 give a scientific explanation by Professor R.A.Lyttleton, F.R.S., a good friend of The Don, on the precise mechanics behind swing bowling. This was one of the first attempts at explaining why a cricket ball swings in such a way, and the fundamentals are more or less correct. More recent experimental studies that improved on Lyttletons theoretical explanation have been carried out, and some references are listed below.
