About this episode
In this episode of Field Notes, Professor Hannah Fry and Michael Stevens (Vsauce) begin with a Persian word for a smell Hannah cannot detect on a freshly washed plate.
From the Sapir-Whorf hypothesis and Russian words for blue to emotions and identity, Hannah and Michael investigate how language may shape our experience of the world.
Then, your questions. How fast would you need to throw a rock for it to escape Earth? What is the planet's escape velocity? Could it survive the atmosphere, or would it take something the size of the Chicxulub asteroid to make it out?
How does soap kill germs? Why does bleach feel slippery on your hands?
And can a scientific theory be completely wrong but still appear to work?
Join them, as they explore linguistics, psychology, colour perception, space travel, bacteria, viruses and, of course, the scientific method.
