Here is a question about this article: Muslim scientists contributed to advances in the sciences. They placed far greater emphasis on experiment than had the Greeks. This led to an early scientific method being developed in the Muslim world, where progress in methodology was made, beginning with the experiments of Ibn al-Haytham (Alhazen) on optics from circa 1000, in his Book of Optics. The most important development of the scientific method was the use of experiments to distinguish between competing scientific theories set within a generally empirical orientation, which began among Muslim scientists. Ibn al-Haytham is also regarded as the father of optics, especially for his empirical proof of the intromission theory of light. Some have also described Ibn al-Haytham as the "first scientist." al-Khwarzimi's invented the log base systems that are being used today, he also contributed theorems in trigonometry as well as limits. Recent studies show that it is very likely that the Medieval Muslim artists were aware of advanced decagonal quasicrystal geometry (discovered half a millennium later in the 1970s and 1980s in the West) and used it in intricate decorative tilework in the architecture.
What is the answer to this question: Regarding the intromission theory of light, who showed the first proof?
****
So... Ibn al-Haytham


Here is a question about this article: Eisenhower was a golf enthusiast later in life, and joined the Augusta National Golf Club in 1948. He played golf frequently during and after his presidency and was unreserved in expressing his passion for the game, to the point of golfing during winter; he ordered his golf balls painted black so he could see them better against snow on the ground. He had a small, basic golf facility installed at Camp David, and became close friends with the Augusta National Chairman Clifford Roberts, inviting Roberts to stay at the White House on several occasions. Roberts, an investment broker, also handled the Eisenhower family's investments. Roberts also advised Eisenhower on tax aspects of publishing his memoirs, which proved financially lucrative.
What is the answer to this question: What was Clifford Roberts by profession?
****
So... investment broker


Here is a question about this article: Stanley Crouch wrote in a New York Daily News piece "Obama's mother is of white U.S. stock. His father is a black Kenyan," in a column entitled "What Obama Isn't: Black Like Me." During the 2008 campaign, the African-American columnist David Ehrenstein of the LA Times accused white liberals of flocking to Obama because he was a "Magic Negro", a term that refers to a black person with no past who simply appears to assist the mainstream white (as cultural protagonists/drivers) agenda. Ehrenstein went on to say "He's there to assuage white 'guilt' they feel over the role of slavery and racial segregation in American history."
What is the answer to this question: What did Ehrenstein say Obama does for white people?
****
So...
assuage white 'guilt'
