How american music has changed over the past 50 years

I was in my second year at high school, grammar school to be precise, and already at the age of 12 I was required to choose between arts and science. In fact my father chose for me and I don't remember being asked.

But was significant, as every year is for science: But nature, and investigations, are continuous. It is possible to pick out turning points though, and that's what Dr Jack Carmody will do for us this morning, ranging from physiology to computing.

He's as wistful as I am about the passing of time. Can it really be 50 years since those idyllic summer afternoons when my brother and I played table-tennis after school while listening to the ABC radio broadcasts of the Olympic Games in Melbourne? Yes, it is, and that truth is a reminder that every year time passes faster, the most unsettling aspect of relativity!

But was more important for scientific reasons and a retrospective venture should be a reminder of how much our biomedical thinking has altered in that twinkling of an intellectual eye.

No less important, was significant for me, too, and not remotely because of the beginning of television. Rather, it was because in that year I really learned for the first time, what science is and how it should be done.

It was my second-last year at school and I had a superb teacher of mathematics, physics and chemistry, who placed great emphasis on the performance of laboratory work rather than textbook learning. In particular, I remember when studying Boyle's Law that we plotted our results graphically and made sense of them by a mathematical transformation.

It was a revelation to me and I can still recall the thrill of discovering the indissoluble relationship of science and mathematics. Then three years later, as a medical student, I encountered physiology, the study of how the healthy body functions, and under the guidance of the charismatic Professor Budtz-Olsen I learned that the same principles apply to medical science.

I was beginning to realise that science is our attempt to understand the physical and biological world which we inhabit by careful observation and measurement, together with thorough analysis of what we find. I came to recognise, too, as I have emphasised to my medical students ever since, that clinical medicine and science have precisely the same intellectual basis.

We perceive or are presented with a question or a problem, and then we gather as much data as we can before attempting to formulate a diagnosis or hypothesis.

Each is provisional and must be subjected to further tough scrutiny. Anything less is sloppy and dangerous. It must all be thoroughly and truthfully documented of course, in patients' and laboratory records; it must be written and published as journal articles and books.

Otherwise it is futile.

I realised some of that intoo. I loved chemistry and that book enhanced the love affair, it was lucid and thrilling to read. Not only were my scientific interests and insights developing in the mids, so was biomedicine. But that had been just as true even 50 years earlier. This year,we are, or should be, celebrating the award of the Nobel Prize for Physiology and Medicine to Camillo Golgi and Santiago Ramon y Cajal, two neuroscientists though that word had not been coined then.

Their prize was a recognition of those two crucial aspects of science which I have mentioned. Golgi devised a powerful new method and Cajal made outstanding use of it. Tissues must be stained with dyes to make their constituents visible under the microscope.

The problem with the study of the brain and other nervous tissue had been that its cells are so dense that the structural detail was impenetrable, like a tropical forest or a satellite photograph of Calcutta.

Golgi's method stains only few cells but outlines them fully, though Golgi did not realise the significance of what he saw. Cajal did, and his work forced scientists to accept that, like every other tissue, the brain is comprised of individual cells.

This discovery raised a profound question: At about that same time, Charles Sherrington coined the term 'synapse' for those points of functional contact and Ernest Starling discovered secretin, the first documented hormone, or chemical messenger.

Thus, years ago, the curtain was opened on a whole new era of bioscience and certainly much was discovered in the following 50 years. Even more scientific fireworks were ignited in the middle of the 20th century, 50 years ago, and we are still reaping the intellectual and therapeutic benefits.

So what was happening in medical science in the mids, and why was it important? It was certainly the beginning of the era of what we now call 'molecular biology'. InJames Watson ad Francis Crick had, with a disarmingly short paper in 'Nature', revealed the structure of DNA, desoxyribose nucleic acid, and with it the mechanism of genetic replication.Looking back from the edge of a new millennium, it is difficult not to be proud of what the federal government has tried to achieve these past fifty years.
