The mathematicians in the Walhalla
The Walhalla is a neo-classical hall of fame which honours the most important people in German history. It was conceived in 1807 by Ludwig I of Bavaria (king from 1825 to 1848) and its construction took place between 1830 and 1842 designed by Leo von Klenze.
The Walhalla was inaugurated on October 18, 1842 with 96 busts and 64 commemorative plaques for people with no available portrait and everything was presided by the great King Ludwig:
Among all these very famous people related with the German history there are some… of course… mathematicians who share this space with Bach, Göethe, Beethoven, Guttemberg, Luther, Otto von Bismarck,… First of all, Dürervis the great German painter from the Renaissance who applied a lot of perspective new techniques to his paintings:
The great astronomers are also here. Regiomontanus,…
Herschel,…
Copernicus,…
and Kepler:
The great Leibniz…
and the greatest Gauss (added in 2007), also have their busts in this hall of fame:
Finally, Albert Einstein’s bust was added in 1990:
I must say that the commemorative plaques also mention Alcuin of York, Albertus Magnus and the Venerable Bede, all ot them related with the wonderful Arithmetics!
Come to Regensburg to see this beautiful (and strange) place!

This was one of the great moment in my last holidays in England! Newton and me together in the same picture! (I must thank the guard because he allowed me to take this picture) Today is 25 December and this is the reason because I am publishing today this picture: Newton was born on December 25, 1642 (Julian Calendar) so… Happy Birthday Great Mind!
Sir Isaac Newton (1642-1727) [by Sir Godfrey Kneller (1646-1723)]
An immensely influential mathematical scientist, in one year (1665-6), when driven from Cambridge by plague, Newton formulated a series of important theories concerning light, colour, calculus and the ‘universal law of gravitation’. According to tradition, he developed the latter theory after seeing an apple fall from a tree. He published Principia (1687) and the Optiks (1704), and was knighted in 1705. Newton was President of the Royal Society from 1703 until his death.
Newton is not alone and he is accompanied by other great English scientist like Edmund Halley. The portrait of Halley is attributed to Isaac Whood (1688-1752) from 1720. Halley has a chart showing his predicted path accross Southern England of the total solar eclipse of 22 April 1715.
Edmond Halley (1656-1742)
Astronomer. At the age of twenty-two in 1678 he published his catalogue of the stars of the southern hemisphere, and in 1705 his celebrated work on comets. Halley published Newton’s Principia at his own expense, 1687; he was appointed Astronomer Royal in 1721. He successfully predicted the reappearance of the great comet in 1758 (‘Halley’s Comet’).
Sir Christopher Wren (showing a plan of St. Paul’s Cathedral) is also in the Gallery:
Wren was an architect and scientist. After the Great Fire of 1666, he rebuilt St. Paul’s Cathedral and many of the London City Churches; his work includes the Sheldonian Theatre in Oxford (1664-9), Trinity College Library in Cambridge (1674-84), Chelsea Hospital and Greenwich Hospital (from 1696). He was professor of Astronomy at Oxford and later President of the Royal Society.
Herschel and Boyle are also exhibited in the Gallery but it was almost impossible to take a picture of them so it’s better if you go to the National Portrait Gallery web and you’ll see better pictures of them.
Before ending this post, we must look at this anamorphic picture of King Edward VI:
Edward VI 1537-53 by William Scrots (active 1537-53). Oil on panel, 1546.
This unusual portrait of Edward was painted in 1546 the year before he became king. He is shown in distorted perspective (anamorphosis), a technique to display the virtuosity of the painter and amaze the spectator. Anamorphic portraits were relatively popular in mainland Europe at this time, but this painting was considered particularly remarkable […].
The anamorphosis is a very interesting mathematical technique which must be explained in detail but I am not going to do it now.
MERRY CHRISTMAS… or ….
HAPPY NEWTON’S BIRTHDAY!

The Museum of the History of Science (and VI)
A space dedicated to Herschel’s instrument is found upstairs. The picture shows a Newtonian relector by William Herschel…
famous for discovering the planet Uranus and building very large reflectors. This is a 7-ft (focal length) model, the type used in the discovery of Uranus.
There is also a large room dedicated to the History of Electricity, Magnetism, Chemistry and Medicine but I am going to finish this serie of posts here. Have you enjoyed? You must go to Oxford to be really happy.

William Herschel’s house in Bath
Nowadays, Herschel’s house in Bath hosts the Museum of Astronomy of this beautiful city in Somerset. The house has a plaque indicating that it’s Herschel’s house in Bath:
William Herschel was born in Hanover the in November 15, 1738. His father Isaak was oboist in the Hannover Military Band and after the defeat in the Battle of Hastenbeck, Isaak sent his sons to seek refuge in England in late 1757 (in those times, England and Hanover were ruled by the King George II of Hanover). In England, William began to study English and music and he is important because of his musical compositions. Herschel moved to Sunderland in 1761 and became member of the Newcastle orchestra as first violin for one season. Then, he moved to Leeds, Halifax and Bath, where he became organist of the Octagon chapel.
The house is full of musical instruments as you can see in this rooum set as his office:
His important musical career allowed him to be intereseted in astronomy, optics and mathematics and he started to build his own reflecting telescopes. Around 1775 Herschel was a very experimented astronomer and he could spend more than 15 hours diary observing the heaven and pulling his lens. In March 1781, he was looking for double stars when noticed a new object in the night heaven. He thought that it was a comet but after a lot of series of observations, he determined that the new object was a new planet beyond the orbit of Saturn. He called it “Georgium sidus” (Georgian star) after king George III although the new planet was known as “Heschel” in France after becoming its name “Uranus”. Herschel was awarded the Copley Medal and elected fellow of the Royal Society of London in 1782. In that year, he and his sister moved to England where he was appointed to King’s Astronomer and continued making new and great telescopes. He constructed more than 400 telescopes with which he discovered two moons of Saturn (Mimas and Enceladus) and two moons and the rings of Uranus (Titania and Oberon) among several other discoveries. His first observation of Uranus was made in this house in Bath (19 New King Street). In fact, one of the most interesting parts of the museum is the garden from where he did this important discovery:
There is an armilar sphere In the garden and a plaque that says:
Here lived Scientist and Musician Sir William Herschel (1738-1822) from where he found the planet Uranus, march 13th, 1781. He also discovered Infrared radiation in 1800. And his sister Caroline Herschel, early woman scientist (1750-1848), hunter of comets.
The museum has a humble collection of astronomical objects where you can find astrolabes, armilar spheres, an orrery,…
The astrolabe of the picture is a brass planispheric Hindu astrolabe, inlaid with silver Sanskrit script. It was commisioned in jaipur, India, in 1836.
We can also see a replica of Herschel 7-foot telescope next to the desktop in the main entrance:
This is a very interesting mathematical visit in Bath. Furthermore, everybody is in the centre of the city visiting the Roman baths and the abbey so you can visit the museum accompanied only by a few number of people. Breathe the air of the science!
Herschel died in August 25, 1822 in Slough and he was buried in the St. Laurence’s Church in Upton.
