Governments, employers, and other interested third parties still look to traditional institutions of education to verify that learning has taken place. Schools and colleges thus play the same centralized, closed system role that banks do in the financial system. Like banks that ensure the validity and authenticity of…
A roleplaying game is part improvisational theater, part storytelling, and part game. It is played by a gamemaster who runs the game and a group of players who pretend to be characters. These characters are created by the players, given a history and personality, and then further defined by a set of statistics that…
I realised I had to write The Bees because when I started to read about the actual creature, there were so many extraordinary entomological facts - like the annual massacre of the males, and the fact the drones DO NO WORK their whole lives, that my imagination was fired. I suddenly saw this celebrity sexual minority…
The first characteristic is living in an artificial environment. Humans established cities and converted the space we live in, to the utmost degree, into an artificial environment. We carry out our lives surrounded by houses, roads, water and sewer systems, automobiles, trains, and electricity. Waking up early, riding…
It is not exaggerating to say that there is quite a close analogy between an artilect trying to communicate with a human being, and a human being trying to communicate with a rock. To make another analogy, consider your feelings towards a mosquito as it lands on the skin of your forearm. When you swat it, do you stop…
The standard DNA 'prism' is a gel electrophoresis column, that is, a long tube filled with jelly through which an electric current is passed. A solution containing the scissored stretches of DNA, all jumbled together, is poured into one end of the tube. The DNA fragments are all electrically attracted to the negative…
‘Volition is a funny thing,’ Zinda says. ‘The jewels don’t just respond to what we want, but what we would want if we were wiser or smarter or knew more. The zoku as a whole tries to extrapolate what you really need, rather than just what you are asking for, and in line with everybody’s volition. I’ll give you an…
As a matter of fact it was not until 1940 that Selkovski invented the purple alga Porpbyrococcus fixator which was to have so great an effect on the world's history. . . . Porpbyrococcus is an enormously efficient nitrogen-fixer and will grow in almost any climate where there are water and traces of potash and…
It is logically possible to postulate organisms composed of pure hardware, capable of metabolism but incapable of replication. It is possible to postulate organisms composed of pure software, capable of replication but incapable of metabolism. And if the functions of life are separated in this fashion, it is to be…
As all regions below are replenished with living creatures, (not only the Earth with Beasts, and Sea with Fishes and the air with Fowls and Insects, but also standing waters, vineger, the bodies and blood of Animals and other juices {49} with innumerable living creatures too small to be seen without the help of…
“We bought it because it matched our logo,” Brewster Kahle told me when I met him there, and he wasn’t kidding. Kahle is the founder of the Internet Archive and the inventor of the Wayback Machine. The logo of the Internet Archive is a white, pedimented Greek temple. When Kahle started the Internet Archive, in 1996…
There was a certain kind of beauty, a prettiness that everyone could see. Big eyes and full lips like a kid’s; smooth, clear skin; symmetrical features; and a thousand other little clues. Somewhere in the backs of their minds, people were always looking for these markers. No one could help seeing them, no matter how…
When the world went on a single currency, they'd tried to coordinate it with the food rationing in some way, hoping to eventually eliminate the ration books, so they'd made the new currency K's, kilocalories, because that's the unit for measuring the energy equivalent of food. But a person who eats 2,000 kilocalories…
Control of fire and the capacity for cooking led to major anatomical and residential changes for early humans, starting more than a million years ago. However, little is known about what transpired when the day was extended by firelight. Data from the Ju/’hoan hunter-gatherers of southern Africa show major differences…
In metric, one millilier of water occupies one cubic centimeter, weighs one gram, and requires one calorie of energy to ehat up by one degree centigrade--which is 1 percent of the difference between its freezing point and its boiling point. An amount of hydrogen weighing the same amount has exactly one mole of atoms…
That's not a problem. The CO2 that's released by humans (and animals) is produced by metabolising carbon from food, and the food comes from plants that have been grown recently. During their growth, the plants have absorbed an equivalent amount of CO2 from the atmosphere. Even when eating meat, the animals are…

Mix up a batch of 50/50 water and glue, dissolve a spoonful of Borax in more water, then mix the whole mess together. (If you want real numbers, mix 1/4 c water with 1/4 glue & dissolve 1 tsp Borax in 1/8 c water, but really, you can be pretty slapdash about this.) As you knead it, the slime will quickly start…
And the answer is, ‘yes.’ I think there’s three main lessons we can learn: First, there’s no one correct diet, but diversity is the key. So, depending on where you live, you can eat very different things, but you need diversity. We lack the ability to synthesize many nutrients that we require for life, nutrients and…
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…
