Input: Read this: 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.
Question: Ibn al-Haytham wrote about his work around the year 1000, what was it?

Input: Read this: Rule of law implies that every citizen is subject to the law, including law makers themselves. In this sense, it stands in contrast to an autocracy, dictatorship, or oligarchy where the rulers are held above the law. Lack of the rule of law can be found in both democracies and dictatorships, for example because of neglect or ignorance of the law, and the rule of law is more apt to decay if a government has insufficient corrective mechanisms for restoring it. Government based upon the rule of law is called nomocracy.
Question: According to the rule of law, who must obey the laws?

Output: every citizen

Improvements in public health began significantly reducing rates of tuberculosis even before the arrival of streptomycin and other antibiotics, although the disease remained a significant threat to public health such that when the Medical Research Council was formed in Britain in 1913, its initial focus was tuberculosis research.
Question: What British health organization made tuberculosis its top priority at its start?
