QUES: 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.

QUES: Possibly the first house erected within the site was that of a Sir William Blake, around 1624. The next owner was Lord Goring, who from 1633 extended Blake's house and developed much of today's garden, then known as Goring Great Garden. He did not, however, obtain the freehold interest in the mulberry garden. Unbeknown to Goring, in 1640 the document "failed to pass the Great Seal before King Charles I fled London, which it needed to do for legal execution". It was this critical omission that helped the British royal family regain the freehold under King George III.

Which king failed to execute Goring's freehold document before fleeing to London?
What is the answer?
ANS: King Charles I
QUES: As of 2013 the City of Paris had 1,570 hotels with 70,034 rooms, of which 55 were rated five-star, mostly belonging to international chains and mostly located close to the centre and the Champs-Elysees. Paris has long been famous for its grand hotels. The Hotel Meurice, opened for British travellers in 1817, was one of the first luxury hotels in Paris. The arrival of the railroads and the Paris Exposition of 1855 brought the first flood of tourists and the first modern grand hotels; the Hotel du Louvre (now an antiques marketplace) in 1855; the Grand Hotel (now the Intercontinental LeGrand) in 1862; and the Hotel Continental in 1878. The Hotel Ritz on Place Vendome opened in 1898, followed by the Hotel Crillon in an 18th-century building on the Place de la Concorde in 1909; the Hotel Bristol on rue de Fabourg Saint-Honore in 1925; and the Hotel George V in 1928.
