The Royal Observatory

Blackford Hill View, Edinburgh EH9 3HJ

A new observatory for Edinburgh was opened in 1896 on top of one of the Braid Hills. It was made possible by the largesse of James Ludovic Lindsay, 26th Earl of Crawford and 9th Earl of Balcarres, a keen and extremely wealthy amateur astronomer, who left his instruments and library to the Scottish nation – now forming the world-renowned Crawford Collection. The situation of the observatory gives it spectacular vistas over the city, Salisbury Crags and Arthur’s Seat. The observatory is still in use and is home to the University of Edinburgh’s Institute of Astronomy and the UK Astronomy Technology Centre (an establishment of the UK’s Science and Technology Facilities Council), Higgs Centre for Innovation (a business incubator and innovation facility), several spin-off companies and a Visitor Centre.

It is possible to visit the observatory, but only by prior arrangement. You can find out how to book from the link the the observatory’s website below.

Merchiston Campus, Napier University, 10 Colinton Road, Edinburgh EH10 5DT

Now on the campus of Napier University, Merchiston Castle was once the family home of John Napier (1550–1617). It was here that Napier developed the concept of logarithms. Napier was inspired by the work of Paul Wittich, one of the assistants of the famous Danish astronomer Tycho Brahe, whose work was brought back to Scotland by John Craig, a Scot who taught mathematics at the University of Frankfurt an dem Oder. Logarithms have many important applications, including plotting the tranjectories of the rockets that took the first men to the moon.

No public access.

The Camera Obscura at the top of the Royal Mile

549 Castlehill, Edinburgh EH1 2ND

Edinburgh is home to the oldest camera obscura in Britain, which first opened in 1853. The original proprietor of this popular tourist attraction was Maria Theresa Short, who came from a family of Edinburgh scientific instrument makers and had previously run a Popular Observatory on Calton Hill, before this was closed by the City Council in 1851. The camera obscura allows visitors to view scenes of the surrounding streets, projected onto a large table in the viewing room. Nowadays the other rooms in the tower are given over to a variety of exhibitions on optics.

The Camera Obscura and World of Illusions is open to the public on purchase of a ticket. See link below for times and prices.

Former Waterson's sealing wax factory. 46 Pleasance, Edinburgh EH8 9TJ

John James Waterston (1811-83) lived in a house on St John’s Hill, next to the sealing wax factory owned by his family. The house is long since gone, but the factory building still stands. Waterson, a surveyor by profession, wrote a paper on the kinetic theory of gases, which he submitted to the Philosophical Transactions of the Royal Society in 1845. It was rejected by the referee, Sir John William Lubbock, as ‘nothing but nonsense’. Only after Waterston’s death was it realised that the paper had prefigured the later theory of Rudolf Clausius and James Clerk Maxwell.

Birthplace of James David Forbes

86 George Street, Edinburgh EH2 3BU

James David Forbes, who was born at this address, pipped his mentor David Brewster to the post of Professor of Natural Philosophy at the University of Edinburgh in 1833, much to the disgust of the latter. As Brewster was aware, Forbes’ appointment owed more to political connections rather than to his scientific reputation. Nonetheless, he went on to do important research on the polarisation and refraction of radiant heat. This work revealed the similarity of heat to visible light, promoting the idea of a continuous spectrum of radiation. He also taught Edinburgh’s most famous physicist, James Clerk Maxwell.

The ground floor of the house is now a shop.

Royal Mile, Edinburgh EH1 1SG

In the centre of the High Street close to this spot in the 17th century stood the so-called ‘luckenbooths’. In one of these was the family home of John Keill. Keill deserves the blame for inspiring the acrimonious priority dispute between Sir Isaac Newton and Gottfried Leibniz over the invention of the calculus. In 1701 he accused Leibniz of taken Newton’s unpublished work on ‘fluxions’ and publishing it as his own, calling them ‘differentials’. Newton was convinced by Keill of Leibniz’s plagiarism and so began a long and bitter dispute between them and their followers.

Entrance to College Wynd

College Wynd, Cowgate, Edinburgh EH1 1JH

It was close to here that James Gregory, the University of Edinburgh’s first professor of Mathematics, lived between his appointment in 1674 and his death in 1675. Gregory had invented the reflecting telescope in 1663. Although the design predates Newton’s reflecting telescope of 1668, a successfully functioning version was not constructed until several years later. The largest working optical telescope in the UK, constructed in 1962 by the University of St Andrews, was named the James Gregory Telescope in his honour. It is still used by the University’s School of Physics and Astronomy.

No public access.

Edinburgh EH8 8HG

It was on Arthur’s Seat, the great volcanic plug that overlooks Edinburgh, that George Sinclair (d.1696) tested and calibrated the mercury barometer he had developed for estimating the depths of mines. In his book on hydrostatics, published in 1672, he described his barometer as well as a diving bell he had invented. Sinclair was an important advocate of the use of theoretical knowledge for practical ends. Like his contemporary Robert Boyle, Sinclair was also a strong believers in ghosts and spirits, whose existence he saw as proof of the truth of religion.

Charles Glover Barkla’s house

Hermitage of Braid, 69 Braid Rd, Edinburgh EH10 6JF

Now the visitor centre for a nature reserve, this was once the home of Charles Glover Barkla, who became the University of Edinburgh’s eleventh professor of Natural Philosophy in 1913. Barkla won the Nobel Prize for Physics in 1917 for his work on X-rays. He was the first to demonstrate that X-rays could be polarised, showing that they were transverse electromagnetic radiation. Unfortunately his reputation was later damaged by his claim to have identified so-called ‘J-radiation’, a form of short-wave radiation incompatible with the predictions of quantum theory, which turned out to be spurious.

Open to the public.

84 Grange Loan, Edinburgh EH9 2EP

Max Born, who became the second Tait Professor of Natural Philosophy at the University of Edinburgh in 1936, was one of the founders of quantum mechanics. Born in Germany into a distinguished academic family of Jewish descent, he was forced to leave his homeland when he was suspended without pay from his post at Göttingen University by the Nazis. After short spells in Oxford and Bangalore he came to Edinburgh. In 1954, the year in which he retired to his native Germany, he won the Nobel Prize for Physics.
