Imagine you are a typical inhabitant of the United States in 1870.11 You live on a rural farm; you produce most of your food and clothing yourself. Your only sources of light are candles, whale oil, and gas lamps if you’re lucky. If you’re a man, you face gruelling physical labour, sometimes from the age of twelve…
Six years ago, in the distant Trisolaran stellar system, Trisolaris accelerated two hydrogen nuclei to near the speed of light and shot them toward the solar system. These two hydrogen nuclei, or protons, arrived at the solar system two years ago, then reached the Earth.
‘The achievement of the Kaminari-zoku implies that there are other spacetimes. Certainly other regions of the Universe beyond our causal horizon. If rational actors have evolved in them, they will have broken their Planck locks – or worse, evolved natively in an environment with no restrictions on computational…
The scientific worker is brought up with the moral values of his neighbours. He is perhaps fortunate if he does not realize that it is his destiny to turn good into evil. An alteration in the scale of human power will render actions bad which were formerly good. Our increased knowledge of hygiene has transformed…
The numerical results of my calculations show that the quantities of energy required for permanent survival and communication are surprisingly modest. For a society with the same complexity as the present human society on Earth, starting from the present time and continuing forever, the total reserve of energy…
So, myth one is that humans are evolved to eat meat and that Palaeolithic peoples consumed large quantities of meat. Humans have no known anatomical, physiological, or genetic adaptations to meat consumption. Quite the opposite, we have many adaptations to plant consumption. Take, for example, vitamin C. Carnivores…
Thomas Edison invented the light bulb in 1879. What if he had never been born, Would we still have light bulbs? And would they still have been invented in 1879? It turns out that this is not just a philosophical question and the answer is yes, the light bulb would have been invented at roughly the same time. We know…
The material factors which ultimately limit the expansion of a technically advanced species are the supply of matter and the supply of energy. At present the material resources being exploited by the human species are roughly limited to the biosphere of the earth, a mass of the order of 5 X 10^19 grams. Our present…
Geoff Marcy, the University of California at Berkeley astronomer who has found scores of exoplanets, and who has diligently searched for signs of anything artificial in the data, says the silence is significant: “If our Milky Way Galaxy were teeming with thousands of advanced civilizations, as depicted in…
Anthropomorphism means attributing the characteristics of human beings to inanimate things or animals. I have invented the word “pragmamorphism” as a shorthand abstraction for the attribution of the properties of inanimate things to human beings. One of the meanings of the Greek word pragma is “a material object.”…
If the cloud is a vast array of personal computer processors, then why not add your own laptop or desktop computer to it? It in a certain way it already is. Whenever you are online, whenever you click on a link, or create a link, your processor is participating in the yet larger cloud, the cloud of all computer chips…
电 is used in many words relating to modern, electrically-powered things. For example, 电影 (electricity - shadow) means "film", 电视 (electricity - to look at) means "TV", and 电脑 (electricity - brain) means "computer".
A dictionary takes words you're unfamiliar with and puts them in terms you're familiar with. Dictionary of Numbers takes numbers you're unfamiliar with and puts them in terms you can understand. Dictionary of Numbers scans the web pages you visit looking for numbers it can understand. When it finds one, it will give…
Terminator rolls around Mercury just like its sunwalkers, moving at the speed of the planet’s rotation, gliding over twenty gigantic elevated tracks, which together hold aloft and push west a town quite a bit bigger than Venice. The twenty tracks run around Mercury like a narrow wedding band, keeping near the…

Environment-controlling buildings gain or lose their energy as "heat o cool" only through their containing surfaces. Spheres contain the most vololume with the least surface—i.e., have the least possible surface-to-volume ratio. Every time we double the diameter of a spherical structure, we in¬ crease its contained…
In every economic transaction there is a willing buyer and a willing seller. and they agree on a price that benefits both. But there are spillover effects in many economic transactions—costs and/or benefits that are transferred to third parties. Friedman called these spillovers "neighborhood effects." Today, most…
Life is an act of endless creativity. With all its simmering tragedy and occasional catastrophe, a human life is an amazing thing to contemplate and experience. None of us had any special plan laid out for us when we were born. By abandoning the idea that and say, "What's done is done. Now how can I make the best of…
Our children will enjoy in their homes electrical energy too cheap to meter. ... Transmutation of the elements, unlimited power, ability to investigate the working of living cells by tracer atoms, the secret of photosynthesis about to be uncovered, these and a host of other results, all in about fifteen short years…
As every circumstance relating to so capital a discovery as this (the greatest, perhaps, that has been made in the whole compass of philosophy, since the time of Sir Isaac Newton) cannot but give pleasure to all my readers, I shall endeavour to gratify them with the communication of a few particulars which I have from…
