Work, Time and Money

Por
Imagem
Reading guide · economics · September 2026 A series of essays on work, time and money, most of them about Portugal. It started with a question Keynes asked in 1930, whether a richer world would work less, and followed where the answers led: to wages and profits, the State’s accounts, pensions, schooling, firms, housing, children, emigration and immigration, and what growth is for. This page lists them in a reading order, with a line on each.

The Fifteen-Hour Week

Por
Imagem
Essay · economics · September 2026 In 1930 Keynes predicted that within a century the rich countries would be four to eight times richer and would work fifteen hours a week. The first half came true with seven years to spare. The second did not come close, and the machines he feared would cause mass unemployment never did. Ninety-four years of data on output, hours, pay and jobs show where the productivity went: mostly into income rather than time, none of it into idleness, and since 1980, in America above all, a large part of it to the people at the top. Nobody chose that split; it was made for them. This first part follows the hours; the second, Where the Hours Went , follows the income.

(Kilimanjaro - Africa) "Why? Because it is there!" - George L. Mallory Note: "Most people think the famous climbing phrase "because it is there" was first uttered by Edmund Hillary when he and Tenzing Norgay conquered Mount Everest in 1953. Not so. Actually George Leigh Mallory, three decades earlier, said it as he prepared to scale the world's highest peak." "People do not decide to become extraordinary. They decide to accomplish extraordinary things." - Edmund Hillary OK, Rei morto, rei posto.

Anticiclone dos Açores “Passamos a grande Ilha da Madeira, Que do muito arvoredo assim se chama, Das que nós povoamos, a primeira, Mais célebre por nome que por fama: Mas nem por ser do mundo a derradeira Se lhe aventajam quantas Vénus ama, Antes, sendo esta sua, se esquecera De Cipro, Gnido, Pafos e Citera. “Os Lusiadas”, Canto V – Estância 5 Luis de Camões Arquipélago da Madeira Arquipélago (pop. est.: 300 000), 798 km²; capital: Funchal; país: Portugal, estatuto: Região Autónoma.

The Duty to Work

Por

Essay · society · September 2026 For most of recorded history, work was what the lower orders did so that others need not. The idea that a job should be the centre of a life, the source of who we are, what we are worth and what it all means, is a few centuries old, and it did not spread by itself. It was preached, legislated, schooled and enforced, in Portugal until 1976 by the police. The evidence says it serves employers better than it serves the people who hold it.

The Ancestors Who Left Nothing

Essay · biology · September 2026 Thirty generations back you have a billion slots in your family tree and about two thousand pieces of DNA to fill them with. Everyone of European descent is descended from Charlemagne; almost no one carries anything of his. Ancestry runs on two clocks, one exponential and one linear, and the gap between them is where genealogy and genetics part company — and where the newest object in population genetics, a graph that holds the whole history of a species’ DNA, comes in.

A 1996 Master's paper from the Department of Physics at Pennsylvania State University, reproduced in full. It develops an algorithm that finds the automorphisms of a random graph in linear average time, and with them the Variety — Lee Smolin's measure of how well each point of a structure can be told apart from every other, offered as a quantitative handle on complexity in diffeomorphism-invariant theories such as gravity.
