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 energy Luminous energy In photometry, luminous energy is the perceived energy of light. This is sometimes called the quantity of light. Luminous energy is not the same as radiant energy, the corresponding objective physical quantity. This is because the human eye can only see light in the visible spectrum and has different sensitivities to light of different wavelengths within the spectrum. When adapted for bright conditions (photopic vision), the eye is most sensitive to light at a wavelength of 555 nm. Light with a given amount of radiant energy will have more luminous energy if the wavelength is 555 nm than
