Context and question: Many early 19th-century neoclassical architects were influenced by the drawings and projects of Etienne-Louis Boullee and Claude Nicolas Ledoux. The many graphite drawings of Boullee and his students depict spare geometrical architecture that emulates the eternality of the universe. There are links between Boullee's ideas and Edmund Burke's conception of the sublime. Ledoux addressed the concept of architectural character, maintaining that a building should immediately communicate its function to the viewer: taken literally such ideas give rise to "architecture parlante".
What Edmund Burke concept is linked to Boullee's ideas?
Answer: sublime
Context and question: Incandescent light bulbs come in a range of shapes and sizes. The names of the shapes may be slightly different in some regions. Many of these shapes have a designation consisting of one or more letters followed by one or more numbers, e.g. A55 or PAR38. The letters represent the shape of the bulb. The numbers represent the maximum diameter, either in 18 of an inch, or in millimeters, depending on the shape and the region. For example, 63 mm reflectors are designated R63, but in the US, they are known as R20 (2.5 in). However, in both regions, a PAR38 reflector is known as PAR38.
What do the numbers identify in a bulb shape designation?
Answer:
the maximum diameter
