Problem: Tuberculosis:

If a tuberculosis infection does become active, it most commonly involves the lungs (in about 90% of cases). Symptoms may include chest pain and a prolonged cough producing sputum. About 25% of people may not have any symptoms (i.e. they remain "asymptomatic"). Occasionally, people may cough up blood in small amounts, and in very rare cases, the infection may erode into the pulmonary artery or a Rasmussen's aneurysm, resulting in massive bleeding. Tuberculosis may become a chronic illness and cause extensive scarring in the upper lobes of the lungs. The upper lung lobes are more frequently affected by tuberculosis than the lower ones. The reason for this difference is not clear. It may be due either to better air flow, or to poor lymph drainage within the upper lungs.

Problem: During the Napoleonic Wars he was taken seriously by the British press as a dangerous tyrant, poised to invade. He was often referred to by the British as Boney. A nursery rhyme warned children that Bonaparte ravenously ate naughty people; the "bogeyman". The British Tory press sometimes depicted Napoleon as much smaller than average height, and this image persists. Confusion about his height also results from the difference between the French pouce and British inch2.71 cm and 2.54 cm, respectively. The myth of the "Napoleon Complex" named after him to describe men who have an inferiority complex stems primarily from the fact that he was listed, incorrectly, as 5 feet 2 inches (in French units) at the time of his death. In fact, he was 1.68 metres (5 ft 6 in) tall, an average height for a man in that period.[note 11]
What was Napoleon's actual height, in feet and inches?

Answer: 5 ft 6 in

QUES: Idealist notions took a strong hold among physicists of the early 20th century confronted with the paradoxes of quantum physics and the theory of relativity. In The Grammar of Science, Preface to the 2nd Edition, 1900, Karl Pearson wrote, "There are many signs that a sound idealism is surely replacing, as a basis for natural philosophy, the crude materialism of the older physicists." This book influenced Einstein's regard for the importance of the observer in scientific measurements[citation needed]. In 5 of that book, Pearson asserted that "...science is in reality a classification and analysis of the contents of the mind...." Also, "...the field of science is much more consciousness than an external world."
