Chemical compound (Wikipedia)A chemical compound is a chemical substance composed of many identical molecules (or molecular entities) containing atoms from more than one chemical element held together by chemical bonds. A molecule consisting of atoms of only one element is therefore not a compound. A compound can be transformed into a different substance by a chemical reaction, which may involve interactions with other substances. In this process, bonds between atoms may be broken and/or new bonds formed.

Mahatma Gandhi (Wikipedia)Mohandas Karamchand Gandhi (/ˈɡɑːndi, ˈɡændi/; GAHN-dee; 2 October 1869 – 30 January 1948) was an Indian lawyer, anti-colonial nationalist and political ethicist. He is widely acknowledged as one of the 20th century’s most influential people, who employed nonviolent resistance to lead the successful campaign for India’s independence from British rule, and to later inspire movements for civil rights and freedom across the world. The honorific Mahātmā (Sanskrit: “great-souled”, “venerable”), first applied to him in 1914 in South Africa, is now used throughout the world.
