Shakidor Dam failure
Shadi Kaur Dam (also "Shadikor") is a dam located on the Shadi Kaur river about 50 kilometres (31 miles) north of Pasni in Balochistan province of Pakistan. The dam was 485 metres (1,591 feet) long. It was constructed in 2003 at a cost of 45 million Pakistani Rupees ($758,853) to provide irrigation for nearby farms. On February 10, 2005, the dam burst due to heavy flooding caused by heavy rainfall, resulting in the deaths of about 70 villagers due to drowning and dragging their bodies into the Arabian Sea. Emergency search and rescue operations by the Pakistani military saved the lives of approximately 1,200 people.

Claude-Louis Navier was born
Claude-Louis Navier was a French mechanical engineer and physicist who specialized in continuum mechanics and often considered to be the founder of modern structural analysis. He directed the construction of bridges, formulated the general theory of elasticity and established the elastic modulus as a property of materials independent of the second moment of area. His major contribution, however, remains the Navier-Stokes equations (1822), central to fluid mechanics.
