- George Atwood - Atwood’s Machine from A treatise on the Rectilinear Motion and Rotation of Bodies (Cambridge, 1784)

- Description
- As mathematics tutor at Cambridge University in the 1770s and 80s, George Atwood was responsible for introducing students to Newtonianism. To help with this task -- and to quell lingering debates about inertia and the living force of matter -- Atwood fashioned a machine that soon became known eponymously. The machine employed an ingenious system of weights, pulleys and a pendulum clock which demonstrated Newton’s laws of motion.

- Description
- From Johann Bayer’s “Uranometria” (1603), the first ‘true’ star-atlas. This and other copper-engraved images from the book demonstrate a notable feature of this atlas: the sheer beauty of the plates. Alexander Mair, the artist, clearly found some inspiration in the De Gheyn engravings in the Aratea published by Hugo Grotius in 1600, but most of Bayer’s constellation figures have no known prototype. Significantly, each plate has a carefully engraved grid, so that star positions can be read off to fractions of a degree. These positions were taken, not from Ptolemy’s catalog, but from the catalog of Tycho Brahe, which had circulated in manuscript in the 1590s, yet not printed until 1602. Another important feature of the atlas was the introduction of a new system of stellar nomenclature, Bayer assigning Greek letters to the brighter stars, generally in the order of magnitude.

- Description
- Whiston’s representation of the solar system, including a prominent comet. Newton and Edmond Halley had worked hard to demonstrate that comets were predictable, periodic bodies which therefore could not be used to prognosticate divine interventions in the natural order. Yet they also suggested that comets deposited aethers to revitalize a spiritually depleted Earth. Whiston liked this mixture of close geometrical analysis with divine mechanism, and extended the discussion. He argued that comets had been responsible for key moments in the Earth’s natural and biblical history - for instance, it was a great comet that had caused the Deluge. He even equated comets with Hell: as they moved in their highly eccentric orbits, they alternated between the “Darkness of Torment” and the “ungodly Smoak of Fire.” For Whiston, comets thus became “the place of Punishment for wicked Men after the general Resurrection.”
