Episode description
First up, science journalist Julia Rosen talks with host Sarah Crespi about a growing fleet of radar satellites that will soon be able to detect minute rises and drops of Earth’s surface—from a gently deflating volcano to a water-swollen field—on a daily basis.
Sarah also talks with Hui Cao, a professor of applied physics at Yale University, about a new way to generate enormous streams of random numbers faster than ever before, using a tiny laser that can fit on a computer chip.
This week’s episode was produced with help from Podigy.
