after razi where in the city should build a new hospital so arise he designed an experiment he hung it up around different locations to see how quickly they rotted and so determined the place with the cleanest air this was typical of a razi you have a problem you design an experiment to find the answer. during the golden age the dissection of human bodies was considered disrespectful but there was one group of people who knew quite a bit about anatomy butches. albeit the anatomy of animal one of the human. well even though this is just the lamb's heart not a human heart we can still see quite clearly the different compartments the different chain best within the heart this isn't something very familiar to his early physicians of the medieval age. in the seventeenth century william harvey famously carried out his groundbreaking research into the circulation of blood in the function of the heart but in one thousand nine hundred eighty four an ancient document was discovered this was a text written by him in the thief's the thirteenth century arab physicians in it he described the basics

apply the scientific method deriving his conclusions from experiments later chemists like kindi and razi also basing their work on careful experiments and observations and the way we do chemistry today organizing and ordering the elements and looking for trends in their properties well just like the reactivity series that's what job or first started to do. next time we travel to some of the most cutting edge medical facilities in the middle east today that original human genome was six points in ten years and now we can sequence the human genome within six to ten day. we look back at how one scholar from the golden age challenge to accepted ideas to explain the human heart this is the primary circulation that is the scope of it's now obvious but it was. and see how texts from the islamic world was so influential in medical science across the globe for centuries science tend to be a good subject to bring different people from all over the world together. in the next episode of science in a golden age more in the contributions made by scholars join the medieval islamic period in the field
