First-century engineer and mathematician Hero of Alexandria is credited with inventing the world's first vending machine, a coin-operated holy water dispenser. Modern vending machines were introduced in the 18th-century and were restricted chiefly to selling penny gum and candy. In 1926, the invention of a cigarette-vending machine started a trend toward selling higher-priced merchandise, and soft drink and nickel-candy machines soon followed.

Savitskaya is a former Soviet female aviator and cosmonaut who flew aboard Soyuz T-7 in 1982, becoming the second woman in space some 19 years after Valentina Tereshkova. She logged nearly 20 days in space during her career, including three and a half hours spent outside the Salyut 7 space station in 1984, when she became the first woman to perform a spacewalk. Before becoming a cosmonaut, she was a test and sport pilot and a parachutist. What world records did she set?

Who was the first woman conceived through IVF to give birth naturally to a baby of her own?
