Designed by Admiral Sir John Fisher and naval architect Sir Philip Watts, HMS Dreadnought introduced uniform heavy-caliber armament and steam turbine propulsion. Its launch rendered all previous battleships obsolete, triggering a naval arms race among world powers. The ship's superior speed and firepower reshaped naval tactics and global maritime strategy. As the Royal Navy's pride, Dreadnought symbolized British industrial and military might. Its design principles influenced battleship construction for decades. The christening marked a milestone in early 20th-century naval innovation.

On February 10, 1996, IBM’s Deep Blue supercomputer defeated world chess champion Garry Kasparov, marking the first time a computer won a match under standard tournament conditions. This groundbreaking victory highlighted the rapid advancement in artificial intelligence and computing power. Deep Blue was equipped with custom-built processing engines capable of analyzing millions of positions per second. Kasparov, known for his deep preparation and tactical prowess, was stunned by the machine’s calculated play. The match sparked worldwide debate about the future of AI, human–machine competition, and the evolving role of technology in society.

On February 10, 2009, two satellites—Iridium 33 and Kosmos 2251—collided in low Earth orbit at high velocity, destroying both spacecraft. The accidental impact generated hundreds of debris fragments, increasing the risk for other satellites and crewed missions. It marked the first major collision between two intact satellites, highlighting the growing congestion in Earth’s orbital environment. Space agencies and operators raised alarms about collision avoidance and the need for improved tracking systems. The incident led to enhanced international cooperation on space traffic management and debris mitigation efforts.
