On the 150th anniversary of the death of Charles Babbage, we retrace the footsteps of the brilliant but irascible British inventor, mathematician, and engineer. Host Kenneth Cukier investigates why Babbage is hailed by some as the grandfather of the computer, while others argue his contribution is overblown. And could letting go of parts of his legacy help unleash the future of computing?For full access to The Economist’s print, digital and audio editions subscribe at economist.com/podcastoffer and sign up for our new weekly science newsletter at economist.com/simplyscience.  See acast.com/privacy for privacy and opt-out information.

Babbage: From pandemic to twindemic

As the northern hemisphere heads towards its second pandemic winter, some countries have already started to make third doses of vaccine available to their most vulnerable citizens. But scientists disagree about whether offering boosters is the best use of vaccine resources—or necessary at all. And, a big study in Bangladesh finds simple ways to encourage mask use.

Babbage: Booster shot

From the hive of molecular activity inside every cell to how cells self-organise into complex living things and those organisms evolve into different species, host Kenneth Cukier explores the fundamental architecture of life. He also investigates how the power of stem cells could be used to treat genetic diseases and why there is still debate about the origins of modern humans.With Geoffrey Carr, The Economist’s science editor; Dr Alison Woollard, professor of biochemistry at Oxford University; Dr Alena Pance of the Wellcome Sanger Institute of genomics; and Dr Viviane Slon, a paleogeneticist at the University of Tel Aviv.Subscribers can read our essay series exploring how life works from the scale of the molecule all the way up to that of the planet at economist.com/biology-briefs For full access to The Economist’s print, digital and audio editions subscribe at economist.com/podcastoffer and sign up for our new weekly science newsletter at economist.com/simplyscience  See acast.com/privacy for privacy and opt-out information.

Babbage: The building blocks of life

As debates over vaccinating children rage and the Delta variant of covid-19 surges in many countries, what impact will the return to classrooms have on the covid-19 pandemic?

Babbage: Back to school

The 20th Century was a golden age for physics but some of its ideas for explaining the material universe have been thrown into doubt. Could a theory known as entropic gravity usher in a new dawn? Also, how should scientists engage with science deniers? And, the technology behind the next generation of prosthetic limbs.
