From the incredible speed of the Peregrine Falcon to the speed of light and Einstein's understanding, this episode explores speed in the natural world and beyond. Learn about the fascinating adaptations of Peregrine Falcons, the historical attempts to measure the speed of light, and the mind-blowing capabilities of Fugaku, the fastest supercomputer in the world.
Peregrine Falcons have evolved unique adaptations enabling them to reach speeds over 320 km/h for successful hunting.
Einstein's theory of relativity revolutionized our understanding of space-time by highlighting the constancy of the speed of light.

Peregrine Falcons: Masters of Speed and Precision
Peregrine Falcons, the fastest animals on Earth, can reach speeds over 320 kilometers per hour during their stoop dive to catch prey. Their specialized adaptations, such as airflow-guiding nostril nodules and a nictitating membrane to protect their eyes, enable them to handle the immense air pressure and maintain clear vision. Their extraordinary flicker fusion threshold allows them to see in higher temporal resolution than mammals, enhancing their hunting abilities and survival. Despite once being endangered, Peregrine Falcons have made a remarkable recovery, thriving in urban areas, showcasing a success story of conservation efforts.
Exploring the Speed of Light and Scientific Measurements
The speed of light, a fundamental constant in the universe, was a subject of early scientific exploration, notably by Galileo and later confirmed by Danish astronomer Olaf Romer. Ingenious measurement techniques, like shining light through spinning cogs and mirrors, led to accurate estimates of the speed of light. Einstein's theory of relativity highlighted the constancy of the speed of light and the necessity of time dilation to maintain this principle, revolutionizing our understanding of space-time.
Fugaku: The World's Fastest Supercomputer
Fugaku, the world's fastest supercomputer, operates at an astounding speed of 415 petaflops, performing 415 quadrillion computations per second. Built in Japan by Fujitsu and Reichen, Fugaku's cutting-edge technology, including 48-core chips and 160,000 processors, sets new standards in computational power. The computer's design emphasizes parallel processing, akin to efficiently managing multiple supermarket checkouts, optimizing performance while requiring meticulous coordination.
This is a re-airing of a podcast originally released in March 2021.
From the quickest animal in the world to the fastest supercomputer, this episode is all about speed.
Opening with the cries of the peregrine falcon, the team finds out how the bird has evolved to endure flying at more than 200mph.
Then they explain how scientists, starting from Galileo, attempted to measure the speed limit of the universe, the speed of light, and how Einstein understood what it meant.
And they explore the mind-blowing capabilities of Fugaku, the fastest supercomputer in the world.
On the pod are Rowan Hooper, Anna Demming and Timothy Revell.
