Book Review: Where's My Flying Car?

This book has two parts, one looks back and asks why flying cars never came to market, and the other looks forward to what possibilities lay ahead. The author has a background in chip design and nanotechnology, and even became a pilot so he could better evaluate the feasibility of flying car designs. The autogyro, developed in the 1930s by Juan de la Cierva, was a promising candidate for a flying car.

Book Review: Technological Revolutions and Financial Capital

This book develops a theory of a cyclical pattern in the economy. The pattern describes how certain new technologies spread to become a whole new way of structuring society. The author Carlota Perez calls this a technological revolution and it’s associated “techno-economic paradigm”. In this review I want to summarize her theory using less jargon. Even though the book reads like an academic text, and the jargon is used consistently, I want to dig into the idea in more common language.

The SIR Model on novel coronavirus

Since a deadly virus appears to be spreading across the globe, I thought it would be useful to explore how this spread is modeled mathematically, and make some predictions about how quickly this can grow. The simplest model of disease spreading starts by breaking a population up into compartments: S (Susceptible) I (Infected) R (Removed️) Then, the model describes the flow between these compartments. NOTE: This version of the model works over short periods and ignores births and natural deaths.

Compound Growth 📈

There are some ideas that are obvious to a few mathematicians, scientists and economists, but which are not widely understood or appreciated. One of the big important ones is compound growth. “Once you start thinking about growth, it’s hard to think about anything else.” – Robert Lucas, Nobel prize-winning economist Before launching into an explanation, I want to start with a question: “Would you rather be 1000 times richer today, or become 2% richer each day for a whole year?

The Long Now Foundation

The world is changing fast, the last 100 years saw the creation of a global network of airplanes, computers, the internet, nuclear energy, and the discovery, sequencing and editing of the genome. The tendency of politics is to focus on the next election (at least in democracies). The tendency of business is to focus on the next quarter. The engines of our fast-changing modern world tend to focus our attention on the narrow world of right now.
