- Albert Einstein (Wikipedia)
Albert Einstein (/ˈaɪnstaɪn/ EYEN-styne; German: [ˈalbɛʁt ˈʔaɪnʃtaɪn]; 14 March 1879 – 18 April 1955) was a German-born theoretical physicist, widely acknowledged to be one of the greatest and most influential physicists of all time. Best known for developing the theory of relativity, he also made important contributions to the development of the theory of quantum mechanics. Relativity and quantum mechanics are the two pillars of modern physics. His mass–energy equivalence formula E = mc2, which arises from relativity theory, has been dubbed “the world’s most famous equation”. His work is also known for its influence on the philosophy of science. He received the 1921 Nobel Prize in Physics “for his services to theoretical physics, and especially for his discovery of the law of the photoelectric effect”, a pivotal step in the development of quantum theory. His intellectual achievements and originality resulted in “Einstein” becoming synonymous with “genius”. Einsteinium, one of the synthetic elements in the periodic table, was named in his honor.
- Niels Henrik David Bohr (Danish: [ˈne̝ls ˈpoɐ̯ˀ]; 7 October 1885 – 18 November 1962) was a Danish physicist who made foundational contributions to understanding atomic structure and quantum theory, for which he received the Nobel Prize in Physics in 1922. Bohr was also a philosopher and a promoter of scientific research.
- Flute (Wikipedia)
The flute is a member of a family of musical instruments in the woodwind group. Like all woodwinds, flutes are aerophones, producing sound with a vibrating column of air. Unlike woodwind instruments with reeds, a flute produces sound when the player’s air flows across an opening. In the Hornbostel–Sachs classification system, flutes are edge-blown aerophones. A musician who plays the flute is called a flautist or flutist.
