# Hedy Lamarr and computer science

The picture above is the world’s first electronic computer, Colossus, in 1944. Its operators are women.

This picture is Hedy Lamarr, a film star between the 1930s and the 1950s. In 1941, at the height of her film career, she invented an algorithm for spread-spectrum broadcasting. She couldn’t get it taken up at the time, but she won a scientific award for it in 1997. Continue reading

# Bin-packing algorithms

Most of the research on bin-packing algorithms starts in the 1970s and the 1980s, in the USA. One of the noted researchers, Ron Graham, is also a talented juggler and former circus performer. Continue reading
