The British recognised the need for anti-aircraft capability a few weeks before World War I broke out; on 8 July 1914, the New York Times reported that the British government had decided to 'dot the coasts of the British Isles with a series of towers, each armed with two quick-firing guns of special design,' while 'a complete circle of towers' was to be built around 'naval installations' and 'at other especially vulnerable points.' By December 1914 the Royal Naval Volunteer Reserve (RNVR) was manning AA guns and searchlights assembled from various sources at some nine ports. The Royal Garrison Artillery (RGA) was given responsibility for AA defence in the field, using motorised two-gun sections. The first were formally formed in November 1914. Initially they used QF 1-pounder "pom-pom" (a 37 mm version of the Maxim Gun).

What was built around naval installations?

However, the prime example of reference works that systematized scientific knowledge in the age of Enlightenment were universal encyclopedias rather than technical dictionaries. It was the goal of universal encyclopedias to record all human knowledge in a comprehensive reference work. The most well-known of these works is Denis Diderot and Jean le Rond d'Alembert's Encyclopedie, ou dictionnaire raisonne des sciences, des arts et des metiers. The work, which began publication in 1751, was composed of thirty-five volumes and over 71 000 separate entries. A great number of the entries were dedicated to describing the sciences and crafts in detail, and provided intellectuals across Europe with a high-quality survey of human knowledge. In d'Alembert's Preliminary Discourse to the Encyclopedia of Diderot, the work's goal to record the extent of human knowledge in the arts and sciences is outlined:

Who wrote the Preliminary Discourse to the Encyclopedia of Diderot?
Answer: d'Alembert's

Thuringia's leading research centre is Jena, followed by Ilmenau. Both focus on technology, in particular life sciences and optics at Jena and information technology at Ilmenau. Erfurt is a centre of Germany's horticultural research, whereas Weimar and Gotha with their various archives and libraries are centres of historic and cultural research. Most of the research in Thuringia is publicly funded basic research due to the lack of large companies able to invest significant amounts in applied research, with the notable exception of the optics sector at Jena.

What is one company that is able to get investments from large companies?
Answer:
the optics sector at Jena.
