At one meeting, chaired by William Whewell, Coleridge was drawn into a passionate discussion of semantics. It revolved around the question of what exactly someone who works ‘in the real sciences’ (as he had phrased it) should be called. This is how Whewell reported the British Association debate in the Quarterly…
Lavoisier had written an influential seven-page Preface to his Traité Élémentaire, defining his scientific method. This declaration seized young Davy’s imagination. Writing with great simplicity and clarity, Lavoisier championed the idea of precise experiment, close observation and accurate measurement. Above all, the…
The disappearance of the traditional world of the ‘four elements’ was revolutionary. It was as radical in the world of chemistry as Copernicus’s proof that the earth was not the centre of the solar system; or (some said) as Robespierre’s claim that the people, not the king, embodied sovereignty. Moreover, it was…
Over the next decade Herschel’s work began to be widely known by the younger generation of Romantic writers. Byron visited him at Slough in 1811, and viewed the stars through his telescope, which gave him an alarmingly religious experience: ‘The Night is also a religious concern; and even more so, when I viewed the…
Already in a paper of 1802 Herschel considered the idea that ‘deep space’ must also imply ‘deep time’. He wrote in his Preface: A telescope with a power of penetrating into space, like my 40 foot one, has also, as it may be called, a power of penetrating into time past … [from a remote nebula] the rays of light which…
Laplace’s cool confidence in avowing atheistical sentiments was legendary. The story was told that after Napoleon had inspected a copy of Laplace’s Systéme du Monde, he challenged the astronomer about his beliefs. ‘Monsieur Laplace! Newton has frequently spoken of God in his book. I have already gone over yours, and I…
In a bravura passage, Darwin also considers Herschel’s disturbing suggestion that the entire cosmos may eventually wither back into ‘one dark centre’. This implies that the universe not only had a beginning, but will have a physically destructive end, a ‘Big Crunch’. There are hints here too of Milton’s vision of the…
This method of viewing the galaxies (‘to continue the simile I have borrowed from the vegetable kingdom’) presented the entire universe in a new kind of light, with the most radical implications. ‘The heavens are now seen to resemble a luxuriant garden which contains the greatest variety of productions, in different…
Nature vibrates with rhythms, climatic and diastrophic, those finding stratigraphic expression ranging in period from the rapid oscillation of surface waters, recorded in ripple-mark, to those long-deferred stirrings of the deep imprisoned titans which have divided earth history into periods and eras. The flight of…
The muddy bottom of rivers contains great quantities of impure and often inflammable air (carbureted hydrogen gas), injurious to life; [begin page 309] and which remains entangled in the mud till let loose from thence by some accident. This air is produced by the dissolution and decomposition of any combustible matter…
According to legend, the first mathematical formulation of what we might today call a law of nature dates back to an Ionian named Pythagoras (ca. 580 BC-ca. 490 bc), famous for the theorem named after him: that the square of the hypotenuse (longest side) of a right triangle equals the sum of the squares of the other…
Here the most sublime scene ever witnessed in the operating room was presented when the patient placed himself voluntarily upon the table, which was to become the altar of future fame. … The heroic bravery of the man who voluntarily placed himself upon the table, a subject for the surgeon’s knife, should be recorded…
The young specialist in English Lit, having quoted me, went on to lecture me severely on the fact that in every century people have thought they understood the Universe at last, and in every century they were proved to be wrong. It follows that the one thing we can say about our modern 'knowledge' is that it is wrong…
The sun's rays proceed from the sun along straight lines and are reflected from every polished object at equal angles, i.e. the reflected ray subtends, together with the line tangential to the polished object which is in the plane of the reflected ray, two equal angles. Hence it follows that the ray reflected from the…
We should remember that there was once a discipline called natural philosophy. Unfortunately, this discipline seems not to exist today. It has been renamed science, but science of today is in danger of losing much of the natural philosophy aspect.
Branches or types are characterized by the plan of their structure, Classes, by the manner in which that plan is executed, as far as ways and means are concerned, Orders, by the degrees of complication of that structure, Families, by their form, as far as determined by structure, Genera, by the details of the…
After Gibbs, one the most distinguished [American scientists] was Langley, of the Smithsonian. … He had the physicist's heinous fault of professing to know nothing between flashes of intense perception. ... Rigidly denying himself the amusement of philosophy, which consists chiefly in suggesting unintelligible answers…
All of these people, should they desire, can indicate events and details they remember differently. But there is one unfortunate exception. In 1958, Rosalind Franklin died at the early age of thirty-seven. Since my initial impressions of her, both scientific and personal (as recorded in the early pages of this book)…
Rosy's instant acceptance of our model at first amazed me. I had feared that her sharp, stubborn mind, caught in her self-made antihelical trap, might dig up irrelevant results that would foster uncertainty about the correctness of the double helix. Nonetheless, like almost everyone else, she saw the appeal of the…
I was preoccupied with sex, but not of a type that needed encouragement. The mating habits of bacteria were admittedly a unique conversation pieceçabsolutely no one in his and Odile's social circle would guess bacteria had sex lives. On the other hand, working out how they did it was best left to minor minds. Rumors…
