 | TODAY IN SCIENCE HISTORY NEWSLETTER - 27 DECEMBER |
| Feature for Today |
 On 27 Dec 1790, James Blundell was born, an English obstetrician and medical researcher whose experiments led to a successful technique of human blood transfusion. Unless you are a medical student or practictioner, you likely have no idea who Blundell was, or what he accomplished. However, you'll find he was eminent enough to have an entry in Medical Portrait Gallery: Biographical Memoirs of the Most Celebrated Physicians, Surgeons Who Have Contributed to the Advancement of Medical Science (1840). From this you can learn more of the state of medical and surgical practice in the early 19th century, and what Blundell contributed. |

 | On 27 Dec 1831, Charles Darwin set sail from Plymouth harbour on his voyage of scientific discovery aboard a British Navy ship. The Captain Robert FitzRoy was sailing to the southern coast of South America in order to complete a government survey. Darwin had an unpaid position as the ship's naturalist, at age 22, just out of university. Originally planned to be at sea for two years, the voyage lasted five years, making stops in Brazil, the Galapogos Islands, and New Zealand. What was the name of the ship? |
 | On 27 Dec 1956, proof was found of certain cases in the beta-decay of cobalt-60 which indeed did not obey a law which scientists had until then believed. The experiment was conducted by Madame Chien-Shiung Wu. A few months earlier, some scientists may have started to accept that could happen, when a theoretical paper by Lee and Yang proposed the law would have cases in which it was not upheld. What law was the subject of the work by Wu, Lee and Yang? |
