This Day in Scientific History (Robert Hooke, ‘London’s Leonardo’ and Newton Nemesis, Dies)

Mar. 3, 1703— Robert Hooke, considered the foremost experimental scientist of the seventeenth century, died at age 67 in London, having sped his decline by trying different drugs and medical remedies that did nothing to cure his maladies.

Hooke’s achievements were so numerous, in so many different fields, that he has been labeled “London’s Leonardo.” I will list these inventions and discoveries shortly, for those readers (more than a few, I believe) unfamiliar with them.

But right now, I should tell you why I wanted to write about him in the first place.

No matter how staggering or monumental a scientist’s advances might be, these do not interest me in and of themselves. When I was young, you could look these up in a print encyclopedia—and now, even more swiftly, through a Google search. But a few minutes after your research, you would be likely to remember none of what you read.

No, it’s not the cool, objective man in a lab that draws my attention, but another figure in the field of science: the compulsive searcher for knowledge, doggedly and sometimes foolishly pursuing what may seem like dead ends—and then, when he makes his startling discoveries, in a proud defense of his work, revealing that he is subject to the same quirks, jealousies, anxieties, and pettiness as anyone without his brilliance.

Students may not realize it from the dull science texts they have to read, but Hooke was definitely a genius of this latter type. Possessed of abundant curiosity, he became a curious figure in his own right—not just during his own lifetime, but for historians of science who have tried ever since to puzzle out the background of a titan who ranged across physics, astronomy, chemistry, biology, geology, even architecture and naval technology.

Among his accomplishments were:

*improving the design of the compound microscope;

*discovering, observing, and naming the “cell,” the fundamental unit of life;

*writing Micrographia (1665), the first textbook in English to feature observations made under a microscope, beautifully illustrated by Hooke himself;

*inventing the balance spring, the used in mechanical watches, alarm clocks, kitchen timers, marine chronometers, and other timekeeping mechanisms;

* inventing the universal joint, the iris diaphragm, and an early prototype of the respirator;

*formulating Hooke’s Law, which states that the amount of force applied to an elastic object is proportional to how far it stretches;

*theories about fossils and the possibility of long-lost species nearly two centuries before Darwin;

*serving as assistant to the pioneering chemist Robert Boyle, including experiments on air pumps;

*collaborating with Sir Christopher Wren on problems of longitude and comets;

* serving as Chief Surveyor and helping rebuild London after the Great Fire of 1666.

But Hooke was all too human—just how much, though, not known until his diaries were published in 1935. He wrote as quickly as his active worklife allowed, about virtually all aspects of his existence—including his liaisons, indicated by a special symbol, to prevent them from being easily read and understood by prying eyes.

Quarrelsome and paranoid, Hooke was unfortunate enough to make an enemy of a similarly choleric character: Sir Isaac Newton. Hooke, habitually inclined to believe he had been insufficient credit by other scientists, complained in a similar fashion about correspondence he had had with Newton concerning gravity.

For a reader trying to find a modern equivalent of the feud between Newton and Hooke, consider the bitter relationship between NBA Hall of Famers Michael Jordan and Isiah Thomas—in each pair, a legend whose fame extended beyond his field to the wider culture, but who continues to denigrate a rival decades later.

Newton was unlike scientists such as Christian Huygens or Johannes Hevelius that Hooke had contended with: he could carry a grudge forever, displayed what biographer James Gleick has described as “implacable ruthlessness” towards scientific foes, and wielded enormous institutional authority as president of the Royal Society.

(One common explanation for why no portraits of Hooke were made during his life is that Newton ensured that one was removed and destroyed at the Royal Society—a rumor that Dr. Felicity Henderson discussed in a fine2010 blog post for that organization. Thus, the image accompanying this post is an imagined one, from this century, with no certainty that it is like the original.)

Newton also outlived Hooke by nearly a quarter century, ensuring that his fame shone all the brighter, to Hooke’s disadvantage. It was no accident that Alexander Pope would write the epitaph, “Nature and Nature’s Laws lay hid in Night:/God said, ‘Let Newton be!’ and all was light.”

Far from achieving similar celebrity, Hooke came in for mockery on the stage, even during his lifetime. Thomas Shadwell’s 1676 farce The Virtuoso mocked the “new world” that Hooke had announced in Micrographia, leading the scientist to carp in his diary about the reaction of other playgoers who recognized him as the object of the ridicule: “Damned Doggs. Vindica me Deus. People almost pointed."

Far all his brilliance and the distance he had travelled from his humble origins, Hooke could never shake his hyper-sensitivity. Some of it may have derived from his appearance. A sickly child, Hooke developed curvature of the spine at the age of 16 that only worsened with time.

Maybe that was the reason for one of the discoveries about his private life made in his diaries: he had no intimate relationships with adult women of his class, instead consorting with house maids, as well as with his niece Grace.

The latter’s death at age 27 in 1687 was a blow from which Hooke never recovered. His intake of experimental drugs to deal with his mounting maladies (e.g., double vision, near-delusions) grew apace, leaving him essentially bedridden for the last year of his life.

Quotes of the Day (Isaac Newton and Albert Einstein, Demonstrating That Finance Stumps Even Geniuses)

"I can calculate the motions of the heavenly bodies, but not the madness of people."—Sir Isaac Newton, after losing a fortune in Great Britain’s South Sea Bubble of 1720, quoted in Christopher Reed, “The Damn’d South Sea,” Harvard Magazine, May-June 1999

“The hardest thing in the world to understand is the income tax.”—Popularly attributed to Albert Einstein

Flashback: Einstein Comes to America, October 1933

October 17, 1933—Albert Einstein and his wife arrived in New York Harbor on the ocean liner Westernland, then were whisked away from a crowd of reporters by tugboat to New Jersey, where he would take a position with Princeton University’s Institute for Advanced Study. 

His move, as newsworthy as it was, was just one part of what might have been the greatest brain drain in history—the vast exodus of scientists, writers, directors, artists, architects, and other intellectuals who first fled Hitler’s Germany, then the other European powers that fell under the Nazi shadow.

As a Jew, the German scientist had already been marginalized in his own country. 

A Nazi edict on April 7 dismissing politically suspect academics would undoubtedly have caught him in its web anyway, since by the start of the 1933-34 school year that fall fully 15 percent of the nation’s established university teachers had already been cashiered, according to Richard J. Evans’ The Coming of the Third Reich.

Einstein had taken the extraordinarily brave step earlier in the year of denouncing the thuggish crackdown by the regime after the Reichstag fire. He resigned from the Prussian Academy of Science before that organization could accede to the Nazi demand that he be expelled. 

But, since he was visiting America at the time of his denunciation of Hitler’s terror, there was nothing he could do to prevent the seizure of his property.

Joining Einstein among the refugee tide were the following past or future Nobel laureates: Gustav Hertz, Erin Schoringer, Max Born, Fritz Haber and Hans Krebs. Who knows how much of a military advantage Hitler would have gained during World War II if he had not evicted so many?

Staying in America –even a beautiful campus such as Princeton’s—did not prove to be the happiest period in Einstein’s life, however, and for more than the obvious reason that he was now cut off from longtime friends and family. There were also these issues:

* Just like a great forebear in applying the laws of mathematics to the physical universe, Isaac Newton, Einstein devoted himself to an endeavor that consumed his energy with little to show for it. Newton had become sidetracked by alchemy, while Einstein’s unfulfilled passion was for a unified field theory.

* Einstein’s prestige was considerable enough that his letter to FDR warning that Germany could design an atomic bomb would lead to the Manhattan Project. But his socialism and pacifism rendered him so politically suspect that he could not serve on the project.

* The scientist’s political views led him to run afoul of Senator Joseph McCarthy and J. Edgar Hoover. His public statement that all intellectuals called before McCarthy’s committee should refuse to testify led at least one witness to take his advice. Hoover’s paranoia was so wide-ranging concerning Einstein—as attested to by the 1,800 pages in the FBI file—that the agency head even suspected the scientist might be a Communist spy.

For a treatment of the Princeton sojourn of this genius, I recommend renting a DVD of a highly fanciful—but equally delightful—romantic comedy, I.Q., with Meg Ryan and Tim Robbins as the young lovers brought together by Walter Matthau, playing the bushy-haired refugee who in this movie—if not in real life—had a sly twinkle in his eyes during these years.
