Francis Bashforth

Francis Bashforth (8 January 1819, in Thurnscoe, Yorkshire – 12 February 1912, in Woodhall Spa, Lincolnshire) was a British applied mathematician who studied ballistics.

Bashforth studied mathematics at the University of Cambridge, where he was Second Wrangler (second highest-scoring candidate) in the 1843 Tripos examination. Later he was a fellow at St. John's College, Cambridge. He was ordained in the Anglican Church. From 1857 until 1892, he was the school rector at Minting in Lincolnshire.

Between 1864 and 1880 he undertook some systematic ballistics experiments that studied the resistance of air. He invented a ballistic chronograph. He received an award from the British government in the amount of £2000 (equivalent to £218,000 in 2019).[1] At times, he was also a professor of mathematics at the Royal Military Academy, Woolwich.

He also studied liquid drops and surface tension.

The Adams–Bashforth method (a numerical integration method) is named after John Couch Adams (who was the 1847 Senior Wrangler) and Bashforth. They used the method to study drop formation in 1883.[2]
