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…
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…
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…
First and foremost, we crave satisfying work, every single day. The exact nature of this “satisfying work” is different from person to person, but for everyone it means being immersed in clearly defined, demanding activities that allow us to see the direct impact of our efforts. Second, we crave the experience, or at…
Conway’s Game of Life is perhaps best viewed not as a single shorthand abstraction but rather as a generator of such abstractions. We get a whole bunch of useful abstractions—or at least a recipe for how to generate them—all for the price of one. And this points us to one especially useful shorthand abstraction: the…
If they are going to sink below, then the pressure on the vessel is going to rise as Verne talked about in 20,000 Leagues Under the Sea. If the pressure on the vessel is going to rise, then it's going to collapse unless the pressure within the vessel rises. So the captain is slowly letting the vessel sink into the…
He who says “Better to go without belief forever than believe a lie!” merely shows his own preponderant private horror of becoming a dupe. . . . It is like a general informing his soldiers that it is better to keep out of battle forever than to risk a single wound. Not so are victories either over enemies or over…
Not the flowing waters of time but the falling sands of time have given modern poets their favorite metaphor for the passing hours. In England, sandglasses were frequently placed in coffins as a symbol that life's time had run out. "The sands of time are sinking," went the hymn. "The dawn of heaven breaks." But the…
Our sense of touch tells us quite definitely that one body is hot and another cold. But this is a purely quali- tative criterion, not sufficient for a quantitative descrip- tion and sometimes even ambiguous. This is shown by a well-known experiment: we have three vessels con- taining, respectively, cold, warm and hot…
Our little Spaceship Earth is only eight thousand miles in diameter, which is almost a negligible dimension in the great vastness of space. Our nearest star — our energy-supplying mother-ship, the Sun — is ninety-two million miles away, and the nearest star is one hundred thousand times further away. It takes…
The drawback to covering your tracks like this on a daily basis is that it sometimes makes you look like, well, like you’re covering your tracks. People who engage all of their privacy functions sometimes stand out in a transparent society. It may make people suspicious, thinking that you’re up to something. If you’re…
The active pursuit of uplift really took hold as a scientific field during the great flowering of transhuman culture, an era that also gave us the widespread settlement of space, extensive human genetic modification, nanotech, cognitive science, and the digital emulation of consciousness. It is in fact the convergence…
An analysis of the paradoxes to be avoided shows that they all result from a kind of vicious circle. The vicious circles in question arise from supposing that a collection of objects may contain members which can only be defined by means of the collection as a whole. Thus, for example, the collection of propositions…
So, the first priority for getting the highest brain j performance is to consume sufficient amounts of protein each day. Insights are cognitively taxing to the human brain, so it makes sense that fueling our neurotransmitters with high-octane fuel —protein —is essential for high-powered thinking. Next come…
[The] weakness of biological balance studies has aptly been illustrated by comparison with the working of a slot machine. A penny brings forth one package of chewing gum; two pennies bring forth two. Interpreted according to the reasoning of balance physiology, the first observation is an indication of the conversion…
An egg is a chemical process, but it is not a mere chemical process. It is one that is going places—even when, in our world of chance and contingency, it ends up in an omelet and not in a chicken. Though it surely be a chemical process, we cannot understand it adequately without knowing the kind of chicken it has the…
Any artist or novelist would understand—some of us do not produce their best when directed. We expect the artist, the novelist and the composer to lead solitary lives, often working at home. While a few of these creative individuals exist in institutions or universities, the idea of a majority of established novelists…
On the basis of the results recorded in this review, it can be claimed that the average sand grain has taken many hundreds of millions of years to lose 10 per cent. of its weight by abrasion and become subangular. It is a platitude to point to the slowness of geological processes. But much depends on the way things…
To eliminate the discrepancy between men's plans and the results achieved, a new approach is necessary. Morphological thinking suggests that this new approach cannot be realized through increased teaching of specialized knowledge. This morphological analysis suggests that the essential fact has been overlooked that…
