Literary nonsense from a combination of both sources. Though not the first to write this hybrid kind of nonsense, Edward Lear developed and popularized it in his many limericks (starting with "A Book of Nonsense", 1846) and other famous texts such as "The Owl and the Pussycat", "The Dong with a Luminous Nose," "" and "The Story of the Four Little Children Who Went Around the World". Lewis Carroll continued this trend, making literary nonsense a worldwide phenomenon with "Alice's Adventures in Wonderland" (1865) and "Through the Looking-Glass" (1871). Carroll's poem "Jabberwocky", which appears in the latter book, is often considered quintessential
Luminous intensity perceived power emitted in all directions. Luminous intensity is the perceived power "per unit solid angle". If a lamp has a 1 lumen bulb and the optics of the lamp are set up to focus the light evenly into a 1 steradian beam, then the beam would have a luminous intensity of 1 candela. If the optics were changed to concentrate the beam into 1/2 steradian then the source would have a luminous intensity of 2 candela. The resulting beam is narrower and brighter, though its luminous flux remains unchanged. Luminous intensity is also not the same as the radiant
