- Bashar al-Assad (born 11 September 1965) is a Syrian politician who is the current and 19th president of Syria since 17 July 2000. In addition, he is the commander-in-chief of the Syrian Armed Forces and the secretary-general of the Central Command of the Arab Socialist Ba’ath Party, which nominally espouses a neo-Ba’athist ideology. His father and predecessor was General Hafiz al-Assad, whose presidency in 1971–2000 marked the transfiguration of Syria from a republican state into a de facto dynastic dictatorship, tightly controlled by an Alawite-dominated elite composed of the armed forces and the Mukhabarat (secret services), who are loyal to the al-Assad family.
- Riemann hypothesis (Wikipedia)
In mathematics, the Riemann hypothesis is the conjecture that the Riemann zeta function has its zeros only at the negative even integers and complex numbers with real part 1/2. Many consider it to be the most important unsolved problem in pure mathematics. It is of great interest in number theory because it implies results about the distribution of prime numbers. It was proposed by Bernhard Riemann (1859), after whom it is named.
