Welcome back to another episode Everything Under The Sun! This week we have the fantastic mathematician and author Marcus du Sautoy, answering the question ‘Who came up with the names of numbers, and how did they choose them?’ We also work out the answer to Sam's question 'Why do plane's flaps go up when landing, but not when taking off?' as well as Delilah's question 'Do all of our fingers have the same fingerprints?' Lots of fun questions to delve into this week and we look forward to exploring them with you. Have a lovely weekend!
