On 19 May 1906, the Simplon Tunnel was opened. At the time, being 12 miles in length, it was the world's longest railway tunnel, cutting under the Alps between Italy and Switzerland and providing an important trade route.

What construction methods were available for such an ambitious project started at the end of the eighteenth century, and what difficulties had to be overcome? A contemporary account is given in How it is Done: or, Victories of the Engineer (1908).


Book of the Day
Science Is Not a Quiet Life: Unravelling the Atomic Mechanism of Haemoglobin (Series in 20th Century Biology)

On 19 May 1914, Max Ferdinand Perutz was born, the Nobel Prize-winning Austrian-British biochemist who used X-ray diffraction analysis to determine the structure of  the protein molecule that transports oxygen from the lungs to the tissues via blood cells. Today's book pick is: Science Is Not a Quiet Life: Unravelling the Atomic Mechanism of Haemoglobin (Series in 20th Century Biology), by Director Laboratory of Molecular Biology Max F Perutz. In a collection of papers he authored and co-authored, he shows how X-ray crystallography was used to determine this molecule’s complex atomic structure and to unravel the stereochemical mechanisms of its respiratory functions. It introduces isomorphous replacement with heavy atoms which led to the first protein structures and haemoglobin.

It is available from Amazon, typically about Used from $249.71. (As of earlier time of writing - subject to change.)


Quotations for Today
Thumbnail of Reginald Aldworth Daly
At bottom each “exact” science is, and must be speculative, and its chief tool of research, too rarely used with both courage and judgement, is the regulated imagination.
— Reginald Aldworth Daly, Canadian-American geologist (born 19 May 1871). quote icon
Thumbnail of Abraham Pais
There is not a soul on Earth who can read the deluge of physics publications in its entirety. As a result, it is sad but true that physics has irretrievably fallen apart from a cohesive to a fragmented discipline. … It was not that long ago that people were complaining about two cultures. If we only had it that good today.
— Abraham Pais, Dutch-American physicist and science historian (born 19 May 1918). quote icon

A discovery is like falling in love and reaching the top of a mountain after a hard climb all in one, an ecstasy not induced by drugs but by the revelation of a face of nature that no one has seen before and that often turns out to be more subtle and wonderful than anyone had imagined.
— Max Ferdinand Perutz, Austrian-British biochemist (born 19 May 1914). quote icon

Thumbnail of Max Ferdinand Perutz
Max Ferdinand Perutz, born 19 May 1914, is an Austrian-born British biochemist, corecipient of the 1962 Nobel Prize for Chemistry for his X-ray diffraction analysis of the structure of the protein that transports oxygen from the lungs to the tissues via blood cells. He that it is constructed of four protein chains wound together, and that the molecule changes shape when oxygen is added. Perutz was also interested in studying glaciers, making measurements which were the first to show different rates of flow in different parts of the same glacier.
What is the name of the blood protein he analyzed?
