question: Red is the color at the end of the spectrum of visible light next to orange and opposite violet. Red color has a predominant light wavelength of roughly 620–740 nanometres. Red is one of the additive primary colors of visible light, along with green and blue, which in Red Green Blue (RGB) color systems are combined to create all the colors on a computer monitor or television screen. Red is also one of the subtractive primary colors, along with yellow and blue, of the RYB color space and traditional color wheel used by painters and artists. 

In nature, the red color of blood comes from hemoglobin, the iron-containing protein found in the red blood cells of all vertebrates. The red color of the Grand Canyon and other geological features is caused by hematite or red ochre, both forms of iron oxide. It also causes the red color of the planet Mars. The red sky at sunset and sunrise is caused by an optical effect known as Rayleigh scattering, which, when the sun is low or below the horizon, increases the red-wavelength light that reaches the eye. The color of autumn leaves is caused by pigments called anthocyanins, which are produced towards the end of summer, when the green chlorophyll is no longer produced. One to two percent of the human population has red hair; the color is produced by high levels of the reddish pigment pheomelanin (which also accounts for the red color of the lips) and relatively low levels of the dark pigment eumelanin.

question: Bum rate is the speed at which a startup business consumes money. My rate would be $ 50,000 a month when my new media company started. So, I began looking around for individuals who would be my first investors. "Angel money" it was called. But when I reviewed my list of acquaintances to find those who might be able to help, I found the number got small. 

With no other choices, I began meeting with the venture-capital companies. But I was warned they took a huge share of your company for the money they put in. And if you struggled, they could drop you cold. 

As I was searching for "angel money", I started to build a team who trusted me even though I didn't have money for paychecks yet. 

Bill Becker was an expert in computer programming and image processing at a very famous Media Lab at M. I.T. With his arrival, my company suddenly had a major technology "guy" in-house. 

Katherine Henderson, a filmmaker and a former real-estate dealer, joined us as our director of market research. Steve White came on as operating officer. He had worked for the developer of a home-finance software, Quicken. We grabbed him. 

We had some really good people, but we still didn't have enough money. One night, my neighbor, Louise Johnson, came for a visit. She and I were only nodding acquaintances, but her boys and ours were constant companions. She ran a very good business at the time. 

Louise was brilliant and missed nothing. She had been watching my progress closely. She knew I was dying for money and I had prospects but could offer no guarantees of success. 

She told me that her attorney had talked to mine and the terms had been agreed upon. She handed me an envelope. Inside was a check for $ 500,000. 

I almost fell down. I heard her voice as if from heaven. 

"I have confidence in your plan," she said. "You' 11 do well. You're going to work hard for it, but it' s satisfying when you build your own company." 

Who would have thought I'd find an angel so close to home? There were no words sufficient for the moment. We just said good night. She left and I just stood there, completely humbled and completely committed.

question: Jean-Jacques Rousseau (; ; 28 June 1712 – 2 July 1778) was a Francophone Genevan philosopher, writer, and composer of the 18th century. His political philosophy influenced the Enlightenment in France and across Europe, as well as aspects of the French Revolution and the overall development of modern political and educational thought. 

Rousseau's novel "Emile, or On Education" is a treatise on the education of the whole person for citizenship. His sentimental novel "Julie, or the New Heloise" was of importance to the development of pre-romanticism and romanticism in fiction. Rousseau's autobiographical writings—his "Confessions", which initiated the modern autobiography, and his "Reveries of a Solitary Walker"—exemplified the late 18th-century movement known as the "Age of Sensibility", and featured an increased focus on subjectivity and introspection that later characterized modern writing. His "Discourse on Inequality" and "The Social Contract" are cornerstones in modern political and social thought. 

During the period of the French Revolution, Rousseau was the most popular of the philosophes among members of the Jacobin Club. He was interred as a national hero in the Panthéon in Paris, in 1794, 16 years after his death. 

Rousseau was born in Geneva, which was at the time a city-state and a Protestant associate of the Swiss Confederacy. Since 1536, Geneva had been a Huguenot republic and the seat of Calvinism. Five generations before Rousseau, his ancestor Didier, a bookseller who may have published Protestant tracts, had escaped persecution from French Catholics by fleeing to Geneva in 1549, where he became a wine merchant.
