The process was devised in 1844 when a gentleman of Great Harwood, Lancashire, treated cotton fibres with sodium hydroxide. The treatment caused the fibres to swell, shrunk the overall fabric size and made it stronger and easier to dye.
It was improved by H. A. Lowe in 1890. Lowe held the cotton during treatment to prevent it from shrinking, and found that the fibre gained a lustrous appearance.
What process, named after its inventor?

From a museum review article:
“I was able to consult the 1779 edition of Olney Hymns in the Harry Ransom Humanities Research Center. Printed in London by W. Oliver, it was in beautiful condition. The paper was almost as white and supple as it was when it came off the printing press.”
What changed in the late nineteenth century that gives recent books a relatively short life span?

• Addition of acid to the paper-making
process. Acidity causes the paper to
become brittle and crumble
• The primary source of acid in modern paper
is the alum-rosin sizing agent introduced in
the manufacturing process. Size is added so
that writing and printing inks do not feather.
In the presence of moisture, the alum in the
sizing agent generates sulfuric acid.

They are an enigmatic group from Manchester, England, with their
name containing the 1909 Nobel winner for physics (an award he
shared with Ferdinand Braun). They were appointed by Brian Eno
to supervise the re-mastering of his back catalogue.
Last year they drummed up 8 min. of aural bliss, after working with
sound therapists to get advice on how to make the most effective
use of harmonies, rhythms and bass lines. It was allegedly proven
to reduce anxiety by 65% and slow heart rates by 35%. So much
that doctors advise one does not listen to it when driving.
Name them (1 point) and either name the song
or what was the Guinness Records sort of tag it
took on (1 point).

At Syene (now Aswan), some 800 km southeast of
Alexandria in Egypt, the Sun's rays fall vertically at
noon at the summer solstice.
Eratosthenes, who was born in c. 276 BC, noted that
at Alexandria, at the same date and time, sunlight fell
at an angle of about 7° from the vertical. He correctly
assumed the Sun's distance to be very great; its rays
therefore are practically parallel when they reach the
Earth.
Given estimates of the distance between the two
cities, what was he was able to calculate?
