Intelligence has given humans an advantage over other forms of life. But could human intelligence soon be surpassed, and what would this mean for the human race? In his book, “Superintelligence: Paths, Dangers, Strategies,” Nick Bostrom writes machine superintelligence, the surpassing of human intelligence by computer intelligence, may occur within this century.

View a timeline of highlights from advances in artificial intelligence and game playing.

Biomechanics: The Science of Movement

Posted on

When you go for a jog, are you focused only on the miles ahead? Running might seem simple to us, but running requires the effective coordination of hundreds of muscles and joints, as well as the underlying physiological processes that govern and support them. How is your hip extension? Do you tend to overstride when you run? What about your posture?

The basic biomechanics of running involves contact with the ground, “flight time,” stride length, stride rate, and the motion of the joints. Small differences in the interactions of the muscles, joints, and physiology can affect the biomechanics of the runner. Scientists use sophisticated technology to help them understand the details of this complicated process.

Today we celebrate one of humanity’s greatest accomplishments. On July 20, 1969 — 45 years ago today — Neil Armstrong and Buzz Aldrin became the first humans to set foot on the moon. It was the height of the cold war, and the United States poured a huge amount of effort into space exploration as a way of competing with the Soviet Union. The Soviets beat us at many milestones, but the success of our human missions to the moon won the space race soundly for the United States.
