TODAY IN SCIENCE HISTORY
NEWSLETTER - 15 JANUARY

Feature for Today
Thumbnail of On 15 Jan 1759, the British Museum, in Bloomsbury, London, the world's oldest public national museum, opened to the public who were admitted in small groups, by ticket obtained in advance, for a conducted tour. It was established on 7 Jun 1753 when King George II gave his royal assent to an Act of Parliament on 5 Apr 1753 to acquire the collection of Sir Hans Sloane. In his will, he had offered the nation his lifetime collection of 71,000 objects, mostly plant and animal specimens. In return, he requested £20,000 for his heirs (which today would be over £2,000,000). The present museum buildings date from the mid-19th century. Its natural history collection moved to its own museum in 1881. The British Museum set up a laboratory in 1920 for its scientific studies. The General Guide to the British Museum Natural History (1898) describes the building which now houses the museum, which stands on part of the site of the International Exhibition of 1862 at South Kensington.

Thumbnail of Lewis M.  Terman
It is evident, therefore, that one of the most fundamental problems of psychology is that of investigating the laws of mental growth. When these laws are known, the door of the future will in a measure be opened; determination of the child's present status will enable us to forecast what manner of adult he will become.
- Lewis M. Terman, American psychologist (born 15 Jan 1877).
