Disruptive Innovation: Why AI Will Spark Exponential Economic Growth

 The innovation and investment guru Cathy Wood gave a TED talk in December 2023 about 5 pivotal innovation platforms that will (continue) to change the world as we know it. Her group expects to see exponential sustained growth that is fueled by the productivity gains in these areas, especially where they converge. The 5 platforms (AI, Robotics, Energy Storage, DNA sequencing, and blockchain) are described below, with AI in the center. One example she uses is the rapid move to self-driving taxis.

What is Pi Day, and what are the useful uses of Pi?

ChatGPT 4.0 (3/14/2024)

Pi Day is celebrated on March 14th (3/14 in the month/day format) because the date represents the first three digits of π (pi), which is approximately 3.14. Pi is a mathematical constant that represents the ratio of a circle's circumference to its diameter. This ratio is constant for all circles of any size, making pi a fundamental aspect of many mathematical, engineering, and scientific calculations. Here are some of the useful uses of pi:

1. **Circumference and Area Calculations**: Pi is used to calculate the circumference (C = 2πr) and the area (A = πr^2) of a circle, where r is the radius of the circle. These formulas are foundational in geometry and are widely used in various fields such as construction, manufacturing, and design.
