Some physicists dealt with the philosophical questions that arose from the new field by ignoring them (the so-called, “shut-up and calculate” method). Their famous feud was the result of the seemingly contradictory nature of the new field of physics and they were not alone in their struggle to grapple with quantum mechanics. Einstein, however, was uncomfortable with the unintuitive, probabilistic world quantum mechanics and the Copenhagen Interpretation and believed the theory was too incomplete. Niels Bohr was crucial in the development and advocacy of the “Copenhagen Interpretation” of quantum mechanics. This field was a tremendous break from previous physics in its attempt to describe the behavior of the universe in the smallest scales. Despite being friends and colleagues, they fundamentally disagreed on the interpretation of quantum mechanics. Niels Bohr and Albert Einstein are pictured here chatting.

By the time Callendar died in 1964, climate scientists were beginning to draw connections between increasing concentrations of carbon dioxide in the atmosphere and increasing global temperatures.īohr and Einstein, probably taken at Paul Ehrenfest's home in Leiden at Witte Rozenstraat 57. Callendar’s paper made a strong case for the role of fossil fuels in altering the composition of the earth’s atmosphere. In 1937 he presented a paper to the Royal Meteorological Society of the United Kingdom that demonstrated that the average global land temperature had been increasing gradually since the nineteenth century.
In addition to his work on steam engines, Callendar also made significant contributions to the history of climate science. The Steam Tables made it easier to understand the relationship between the properties of steam and the amount of energy a steam engine could produce. Guy never received an advanced degree, but he was highly regarded by steam engineers for his Callendar Steam Tables, which he prepared with his father and periodically revised throughout his life. Son of physicist and inventor Hugh Callendar, Guy was encouraged from a young age to pursue his scientific interests.
Steam engineer, tennis player, and weather watcher, Guy Callendar was a man of many interests.

Not all scientists were so fortunate, as we’ll learn in the first episode of Initial Conditions.Ĭredit: University of East Anglia Archive, contact the University of East Anglia Archive about this image. NBLA may be able to provide copyright contact information. Tyndall’s likeness was captured in many portraits, and his experiments, public lectures, and journals immortalized his important work. John Tyndall is seen here, holding his place in a book with his finger, posing beside some of the most prominent scientific men of his era and among high tech experimental equipment. Sadly, he died prematurely after accidentally overdosing on his insomnia medication. His scientific career was not without drama and he participated in many debates over scientific priority. Tyndall was also driven by his love of mountaineering and his experiences at high altitudes inspired much of his research. Perhaps most notable were his experiments into radiant heat and his discovery of the Greenhouse Effect. After studying at the University of Marburg in Germany, under some of the best experimental physicists Europe had to offer, he rose to renown for his work in diamagnetism. John Tyndall was born around 1820 in Ireland and grew to become an influential physicist. Credit: AIP Emilio Segrè Visual Archives, Zeleny Collection.
