On this day, October 30th, 1826 Niels Abel presented a paper to the French Academy of Sciences that was ignored by Cauchy, who was to serve as referee. The paper was published some twenty years later, well after Abel's death.

The Abel–Ruffini theorem (also known as Abel's impossibility theorem) states that there is no solution in radicals to general polynomial equations of degree five or higher with arbitrary coefficients.

On this day, October 29th, 1675 Leibniz wrote the integral sign ∫ in an unpublished manuscript, introducing the calculus notation that’s still in use today.He is a source of mathematics

On this day, October 28th, in 1703 John Wallis died. Wallis was a british mathematician who introduced the infinity math symbol.
He is also given partial credit for the development of infinitesimal calculus and pi.

On this day, 26 October in 1676 Newton wrote a 2nd letter (via Oldenburg) to Leibniz stating he might have been something too severe in taking notice of some oversights of Leibniz in his letter from the 24th...

On this day, October 25th, 1647 Evangelista Torricelli died. Torricelli was an Italian physicist and mathematician.
Inventor of the barometer, known for 'his' trumpet and the Fermat–Torricelli point in a triangle

[Pim Klingens @pklingens]

A Fermat–Torricelli point in a triangle is a point such that the sum of the three distances from each of the three vertices of the triangle to the point is the smallest possible.
The problem was first raised by Fermat in a private letter to Evangelista Torricelli, who solved it.

On this day, 24th October, 1676 Newton summarized the stages of development of his method of equating areas under curves with infinite sums in the “Epistola posterior,” which he sent to Oldenburg to transmit to Leibniz.

The works of Euclid made the creator of 'Alice in Wonderland' write the following book:
