21st April
On this day in 1702, Maria Winckelmann became the first woman to discover a comet. Her husband Gottfried Kirch wrote:-

Early in the morning the sky was clear and starry. Some nights before I had observed a variable star, and my wife wanted to find and see it for herself. In so doing she found a comet in the sky. At which time she woke me and I found that it was indeed a comet ... I was surprised that I had not seen it the night before.In fact Kirch claimed the discovery for himself and did not give the above account until 1710.

Quotation of the day
From John Maynard Keynes
[Newton's] peculiar gift was the power of holding continuously in his mind a purely mental problem until he had seen through it.
