• Auger effect. First discovered by Lise Meitner in 1922 and then, independently, in 1923 by Pierre Victor Auger.

B

• Bailey–Borwein–Plouffe formula was discovered by Simon Plouffe, who has since expressed regret at having to share credit for his discovery.
• Bechdel test, a gender bias test for films popularised by and named after Alison Bechdel, creator of the comic strip Dykes to Watch Out For, despite her repeated insistence that the test was devised by her friend Liz Wallace.
• Bell numbers have been studied since the 19th century and even medieval Japan, but are named after Eric Temple Bell who wrote about them in the 1930s.
• Bellman–Ford algorithm for computing the shortest-length path, proposed by Alfonso Shimbel, who presented the algorithm in 1954, but named after Richard Bellman and Lester Ford Jr., who published equivalent forms in 1956 and 1958.
• Benford's law, named after physicist Frank Benford, who stated it in 1938, although it had been previously stated by Simon Newcomb in 1881.
• Bertrand's ballot theorem proved using André's reflection method, which states the probability that the winning candidate in an election stays in the lead throughout the count. It was first published by W. A. Whitworth in 1878, nine years before Joseph Louis François Bertrand; Désiré André's proof did not use reflection, though reflection is now the method commonly taught.

In France, the law is known as Mariotte's law, after Edme Mariotte, who published his results later than Boyle, but crucially added that the relation holds only when temperature is kept constant.
