Unexpected Outcome

Comparison of the only known account of the invention of cold water injection to activate an atmospheric engine with contemporary texts on experimental methodology reveals that Newcomen and Calley’s inventive process corresponds with the design of experiments prescribed by Robert Hooke for the Royal Society. Consequently, when an unexpected outcome occurred, they were able to make full application of the findings. Differences between the steam piston experiments of Newcomen and Denis Papin are explored, suggesting that the inventors may have been working in parallel.

Richard Nichols is a science master turned historian of science who celebrates in this book Robert Hooke’s contributions to the arts and sciences. The appreciation brings together comments from Hooke’s Diaries , and other works, on each of his main enterprises, and on his personal interaction with each of his principal friends and foes. Further references to Hooke and his activities are drawn from Birch’s History of the Royal Society, Aubrey’s Brief Lives , and the Diaries of Evelyn and of Pepys. The first section of the book, ‘Hooke the Man’, covers his early years of education at home in Freshwater, at Westminster school and at Christ Church, Oxford, where he soon joined the group of experimental philosophers who set him up as Curator of the Royal Society and Professor of Geometry at Gresham College, Bishopsgate. Hooke’s domestic life at Gresham College is described - his intimate relationships with a series of housekeepers, including his niece, Grace Hooke, and his social life at the College and in the London coffee houses.

Observ. XV. illustrated by Schem. IX. Figur:1 (figure 1 of this paper) in Robert Hooke's Micrographia (1665)1 is a description of Kettering–stone ‘which is brought from Kettering in Northampton–shire, and digg’d out of a Quarry, as I am inform'd’. As Curator of Experiments for the Royal Society from 1662, Hooke was charged by the Society to bring in at every meeting one microscopical observation at least. The minutes of the Society2 record that on 15 April 1663 ‘Mr Hooke showed the Company two Microscopicall Schemas; one representing the Pores of Cork … the other a Kettering Stone, appearing to be composed of Globules; and those hollow ones, each having 3 Coatings, sticking to one another, and so making up one entire firm stone’.

For processes such as water injection in deep geothermal production, heat transfer and fluid flow are coupled and affect one another, which leads to numerous challenges in wellbore structure safety. Due to complicated wellbore structures, consisting of casing, cement sheaths, and formations under high temperature, pressure, and in situ stress, the effects of thermo-hydro-mechanical (THM) coupling are crucial for the instability control of geothermal wellbores. A THM-coupled model was developed to describe the thermal, fluid, and mechanical behavior of the casing, cement sheath, and geological environment around the geothermal wellbore. The results show that a significant disturbance of effective stress occurred mainly due to the excess pore pressure and temperature changes during cold water injection. The effective stress gradually propagated to the far-field and disrupted the integrity of the wellbore structure. A serious thermal stress concentration occurred at the junction of the cased-hole and open-hole section. When the temperature difference between the injected water and the formation was up to 160 °C, the maximum hoop tensile stress in the granite formation reached up to 43.7 MPa, as high as twice the tensile strength, which may increase the risk of collapse or rupture of the wellbore structure. The tensile radial stress, with a maximum of 31.9 MPa concentrated at the interface between the casing and cement sheath, can cause the debonding of the cementing sheath. This study provides a reference for both the prediction of THM responses and the design of drilling fluid density in geothermal development.

On 4 March 1660—61 ‘glass bubbles’ were first introduced to a meeting of the Royal Society. According to the minutes, ‘The King sent by Sir Paul Neile five little glass bubbles, two with liquor in them, and the other three solid, in order to have the judgement of the society concerning them’ (1). The Royal Society responded with remarkable celerity: its amanuensis produced some more drops two days later, which ‘succeeded in the same manner with those sent by the king’ (2). A very full report of the experiments performed was given to the Royal Society on 14 August 1661 by the President, Sir Robert Moray (3). As the Royal Society did not at this time have a normal publication series the report was recorded in the Register Book (4) and first published by Merret as an appendix to his translation of Neri’s Art of Glass (5). Henry Oldenburg lent Sir Robert’s account to the French traveller Monconys in 1663 who made his own translation into French of the prescription for making the drops. Monconys published this prescription in the second part of his Voyages (6). The ‘bubbles’— the solid ones, at least— were what were later to be called ‘Prince Rupert’s drops’. (Those said to contain ‘liquor’ could have been something different, but were probably the same containing vacuoles and no actual liquid.) These objects, glass beads with the form of a tear-drop tapering to a fine tail, made (though that was not generally known at the time) by dripping molten glass into cold water, exhibited a paradoxical combination of strength and fragility not without interest to the materials scientist of the present day, and which could not fail to excite the imagination of natural (and not so natural) philosphers of the 17th century. The head withstands hammering on an anvil, or, as a more modern test, squeezing in a vice, indenting its steel jaws, without fracture: yet breaking the tail with finger pressure caused the whole to explode into powder.

The period which saw the foundation of the Royal Society is rich in names remarkable for original achievement in the field of science, but, if we except Newton—and his first paper appeared eleven years after the foundation of the Society which is now being celebrated—none is more noteworthy than Robert Hooke. Without any advantages of birth or influence, poor in health and poor, as a young man, in worldly goods, he carried out work of the first importance in most branches of science then known, and of one branch, meteorology, he may claim to be the founder. Not only was he outstanding as an experimenter and as the inventor of new instruments, but he had an informed imagination which led him to astonishingly correct anticipations of many advances subsequently to be made. Although to many his name is known only through Hooke’s Law, outstanding figures in the history of science have been loud in his praises. Thomas Young wrote of the ‘inexhaustible but neglected mines of nascent inventions, the works of the great Robert Hooke’, a most apt phrase, since Hooke’s work contains so much that is suggestive and original, which his restless spirit lacked time to develop.

In 1675 Robert Hooke published, as one of his ‘Inventions’, a Latin anagram concerning the ‘true...form of all manner of arches for building’. His discovery was that the shape of a light flexible cord subjected to specified loads would, when inverted, give the required shape of the perfect (masonry) arch to carry those same loads. Hooke knew that the catenary curve was not given by the parabola y = ax 2 , but he was unable to solve the problem mathematically, and the decipherment of the anagram was not published until after his death. Four years earlier Hooke had stated to the Royal Society that the solution to the corresponding three–dimensional problem, that of the shape of the perfect dome, was the cubico–parabolical conoid; that is, the dome was formed by rotating the cubic parabola y = ax 3 about the y –axis. It is shown that the correct form of dome may be evaluated in terms of the integrals erf( t ) and erg( t ). Moreover, an alternative solution as a power series is rapidly convergent, and has a leading term in x 3 followed by a much smaller term in x 7 . Wren's design for the dome of St Paul's Cathedral made use of the idea of Hooke's ‘hanging chain’.
