Gordon Moore, the co-founder of Intel who died earlier this year, is famous for forecasting a continuous rise in the density of transistors that we can pack onto semiconductor chips. His eponymous “Moore’s law” still holds true after almost six decades, but further progress is becoming harder and eye-wateringly expensive to sustain. In this episode of the Physics World Stories podcast we look at the practicalities of keeping Moore’s law alive, why it matters, and why physicists have a critical role to play.
