Happy Pi Day!

Hey! Happy pi day to all my readers!



Here's something cool:
eiπ = -1                                                                      (by Euler’s identity) 
Taking natural logarithm on both sides,
ln (-1) = iπ
 
Hence, π = ln(-1)/i
 







 
Here’s a simple question for pi day:  What does the series above converge at?
 
Anyways, here’s pi to 30 decimal places: 3.141592653589793238462643383279.

Forgot to post, so just adding a Happy Tau Day Here! - 6/28

1001.0: The Mathematics of Quantitative Finance - Part 1

Image
 Hi! Welcome to this 3-part series on the mathematics behind quantitative finance! Took a while to return, but I'm done with IB exams now (well... since mid-May, really. But I've been on holiday or busy on and off since). Anyways, this part of the series will cover: Introduction to Quantitative Finance   Fundamental Mathematics in Quantitative Finance   Financial Instruments and Markets    Rest in Peace to  Jim Simons , whom this series is dedicated to. Jim Simons, founder of Renaissance Technologies and Father of Modern Quantitative Finance Introduction to Quantitative Finance Overview of Quantitative Finance Quantitative finance is a field that uses mathematical models, statistical techniques, and computational tools to understand and solve financial problems. It plays a crucial role in the financial industry by providing methods for pricing complex securities, managing risk, and optimizing portfolios. Quantitative finance integrates a...

111: Begin the New Year with... an Introduction to the Poincaré Conjecture! (Pure Mathematics)

Image
 Hey! It's been a minute since I wrote one of these, so I'm genuinely glad to be back. Happy New Year! I should be more regular now because I'm done with all university applications and I'm relatively free (as free as you can be by year 12). Today I'll be jabbering on a bit about the Poincaré Conjecture, one of the most special (solved) problems in mathematics. The Poincaré Conjecture Image Credit: Clay Mathematics Institute The Poincaré Conjecture is a fundamental problem in the branch of topology, best known as one of the 7 Millennium Prize Problems of the Clay Mathematics Institute. It was one of the most famous and long-standing unsolved problems in the history of mathematics until it was finally proven in 2003 by the Russian mathematician Grigori Perelman. Perelman's proof was a monumental achievement and earned him the Fields Medal and 1 million US Dollars (from the Clay Mathematics Institute) - both of which he declined (which I'll return to later). H...

110: Everything You Need to Know About the Navier-Stokes Equations (Pure Physics and Applied Mathematics)

Image
In the intricate world of fluid dynamics, where the movement of liquids and gases forms the backdrop of countless natural phenomena, the unsolved Clay Institute Millenium Prize Problem of the Navier-Stokes equations stands as a beacon of understanding. These mathematical expressions encapsulate the intricate forces, pressures, and velocities that orchestrate the motion of fluids. George Gabriel Stokes Image Credit: Clay Mathematics Institute Fluid dynamics is a captivating branch of physics and mathematics that delves into the behaviour of fluids in motion. Whether it's the ocean currents, the streams, or the turbulence in a boiling pot, understanding the principles governing fluid motion requires strong mathematical concepts and physics insights. The Navier-Stokes equations, named in honour of the French engineer Claude-Louis Navier and the Irish mathematician George Gabriel Stokes, are the fundamental equations that explain fluid dynamics. In their general form, they can be expre...
