Born #OnThisDay in 1887 was Indian mathematician Srinivasa Ramanujan. Despite having almost no training in mathematics, he is regarded as one of the greatest mathematicians of all time. He became one of the youngest Fellows in the Royal Society's history when he was elected in 1918 at the age of 31.

In L6 #ALevelMaths #FurtherMaths #MathsToday we made our own slide rules (www.sliderulemuseum.com/REF/scales/M...) and learned how to use them for multiplication and division.
Teri won the cosine rule race, where pupils chose slide rule or tables to answer a problem (she used the slide rule).
