Montgolfier brothers
Joseph-Michel Montgolfier (26 August 1740 – 26 June 1810) and Jacques-Étienne Montgolfier (6 January 1745 – 2 August 1799) were paper manufacturers from Annonay, in Ardèche, France best known as inventors of the Montgolfière-style hot air balloon, globe aérostatique. They launched the first piloted ascent, carrying Étienne. Joseph Michel also invented the self-acting hydraulic ram (1796), Jacques Étienne founded the first paper-making vocational school and the brothers invented a process to manufacture transparent paper.

Anouar Brahem
Anouar Brahem (in Tunisian Arabic أنور براهم) (born on October 20, 1957) is a Tunisian oud player and composer. He is widely acclaimed as an innovator in his field. Performing primarily for a jazz audience, he fuses Arab classical music, folk music and jazz and has been recording since at least 1991, after becoming prominent in his own country in the late 1980s.
Charles Goodyear
Charles Goodyear (December 29, 1800 – July 1, 1860) was an American self-taught chemist and manufacturing engineer who developed vulcanized rubber, for which he received patent number 3633 from the United States Patent Office on June 15, 1844.
Goodyear is credited with inventing the chemical process to create and manufacture pliable, waterproof, moldable rubber.
Goodyear’s discovery of the vulcanization process followed five years of searching for a more stable rubber and stumbling upon the effectiveness of heating after Thomas Hancock.[5] His discovery initiated decades of successful rubber manufacturing in the Lower Naugatuck Valley in Connecticut, as rubber was adopted to multiple applications, including footwear and tires. The Goodyear Tire and Rubber Company is named after him.

Annotating with Sage
Whether one uses Sage in the classroom or in research, it is usually helpful to describe to the reader what is being done, such as in the description you are now reading.
Jupyter Annotation
Thanks to a styling language called Markdown and the TeX rendering engine called MathJax, you can type much more in Sage than just Sage commands. This math-aware setup makes Sage perfect for annotating computations.
While the Jupyter notebook does not have as fully-featured a word processor as the SageNB, we can still do a fair amount. To use this functionality, we create a Markdown cell (as opposed to a input cell that contains Sage commands that Sage evaluates).
To do this without the keyboard shortcut, there is a menu for each cell; select “Markdown”.
