A Brief History of Science: As Seen Through the Development of Scientific Instruments
Constable, 2001 - 425 من الصفحات
From the beginnings of history, with gnomons and sundials, through to the twenty-first century and the 26-kilometre underground particle accelerator, the author describes the way that the design and production of scientific instruments has extended the frontiers of science.
Man's desire to understand the universe has led to the making of more and more sophisticated instruments - first to record and measure (Arab numerals, standardised measures), to examine ever more minutely (the microscope, the lens, the prism), on through electromagnets, cathode tubes, thermometers, vacuum pumps, X-rays, counters and accelerators, semi-conductors and microprocessors, down to new instruments now being designed to observe matter at zero temperatures - presenting immense technological problems in the requirement for instruments that can operate in conditions where normal properties no longer hold.

Although he proposed, as an alternative, other simple and primitive elements, he
came nowhere near analytical chemistry, as it began to evolve in the eighteenth
century. As a physicist, Boyle achieved notable results (related in Chapter 5) ...
In the first place, there is then no chemical phenomenon, whether occurring in
nature or the laboratory, that will betray its existence. No-one can smell or taste it,
or, if is a gas, feel it, and it will have no power to corrode, contaminate, or even ...
For example a group of two carbon atoms, C2 . . . will form a compound of six
atoms of monatomic elements, or generally with so many atoms that the sum of
the chemical units of these is equal to six.77 An elementary example of this is
