2011Herbert A. Hauptman, American chemist and mathematician, Nobel Prize laureate (born 1917)^[†]

Herbert Aaron Hauptman was an American mathematician and Nobel laureate. He pioneered and developed a mathematical method that has changed the whole field of chemistry and opened a new era in research in determination of molecular structures of crystallized materials. Today, Hauptman's direct methods, which he continued to improve and refine, are routinely used to solve complicated structures. It was the application of this mathematical method to a wide variety of chemical structures that led the Royal Swedish Academy of Sciences to name Hauptman and Jerome Karle recipients of the 1985 Nobel Prize in Chemistry.

2011A powerful 7.2 magnitude earthquake strikes Van Province, Turkey, killing 582 people and injuring thousands.^[†]

The 2011 Van earthquakes occurred in eastern Turkey near the city of Van. The first earthquake happened on 23 October at 13:41 local time. The shock had a Mww magnitude of 7.1 and a maximum Mercalli intensity of VIII (Severe). It occurred at a shallow depth, causing heavy shaking across much of eastern Turkey and lighter tremors across neighboring parts of the South Caucasus and Levant. According to Disaster and Emergency Management Presidency on 30 October, the earthquake killed 604 and injured 4,152. At least 11,232 buildings sustained damage in the region, 6,017 of which were found to be uninhabitable. The uninhabitable homes left as much as 8,321 households with an average household population of around 7.6 homeless in the province; this could mean that at least around 60,000 people were left homeless. The other 5,215 have been damaged but are habitable. A separate earthquake within the same earthquake system happened on 9 November at 21:23 local time. 38 people were killed and 260 people were injured in the 9 November earthquake.
