Other examples of remarkable societal resilience are more recent. We can consider, for example, the atomic bombing of the Japanese city of Hiroshima in 1945. The bomb the United States dropped was 1,500 times more powerful than any previously used.32 The fireball at the hypocenter of the blast reached several thousand…
For years, many scientists warned of the dangers that asteroids pose to life on Earth, but for many years they weren’t listened to. Even after it was first proposed, in 1980, that the dinosaurs were killed off by a huge asteroid striking the Yucatán Peninsula in Mexico,1 there was, in the words of leading astronomer…
Brooding, she changed the pool into the sea, and made the minnows into sharks and whales, and cast vast clouds over this tiny world by holding her hand against the sun, and so brought darkness and desolation, like God himself, to millions of ignorant and innocent creatures, and then took her hand away suddenly and let…
Briefly stated, the Gell-Mann Amnesia effect is as follows. You open the newspaper to an article on some subject you know well. In Murray's case, physics. In mine, show business. You read the article and see the journalist has absolutely no understanding of either the facts or the issues. Often, the article is so…
As far as Brown is concerned, many abandoned urban communities are postapocalyptic in nature. Such places are rife for community-born transformation. "If you look at cities in the US right now, there are cities or communities in apocalyptic situations," says Brown. She references challenged areas in New York City, New…
"But the divine revenge overtook not long after those proud enterprises. For within less than the space of one hundred years, the great Atlantis was utterly lost and destroyed: not by a great earthquake, as your man saith; (for that whole tract is little subject to earthquakes;) but by a particular' deluge or…
The weather bureau will tell you what next Tuesday will be like, and the Rand Corporation will tell you what the twenty-first century will be like. I don't recommend that you turn to the writers of fiction for such information. It's none of their business. All they're trying to do is tell you what they're like, and…
On certain small planets, drenched with light and heat from a near or a great sun, evolution took a very different course from that with which we are familiar. The vegetable and animal functions were not separated into distinct organic types. Every organism was at once animal and vegetable. Many species, of course…
In this game the floor is the sea. Half—rather the larger half because of some instinctive right of primogeniture—is assigned to the elder of my two sons (he is, as it were, its Olympian), and the other half goes to his brother. We distribute our boards about the sea in an archipelagic manner. We then dress our…
Outside Temperatures. Place a thermometer outside a window so students can make daily calculations and keep a chart reporting the actual temperature and the temperature change from the previous day. Students will see that the change can be a negative number without the temperature falling below 0—an often-confusing…
Filters in a digital world work not by removing what is filtered out; they simply don't select for it. The unselected material is still there, ready to be let through by someone else's filter. Intelligent filters, which is what we need, come in three kinds: A smart person who takes in a lot and tells you what you need…
How should a living organism live? When spring arrives, you open your doors, the wind blows in. The smell of flowers fills the airand colors come back to lifeSometimes when it rains or when it’s foggy out. You can’t help but breathe the air deep into your lungs and experience the feeling of small water droplets…
Leaving the mountains, Ye felt spring was everywhere. The cold winter of the Cultural Revolution really was over, and everything was springing back to life. Even though the calamity had just ended, everything was in ruins, and countless men and women were licking their wounds. The dawn of a new life was already…
The spectrum depends upon light of different colours being slowed by different amounts: the refractive index of a given substance, say glass or water, is greater for blue light than for red. You could think of blue light as being a slower swimmer than red, getting tangled up in the undergrowth of atoms in glass or…
I do not wish here to get into a technical argument about the details of nuclear winter. I will merely summarize my own struggles with the technical issues. I spent a few weeks in 1985 trying to make nuclear winter go away. The phrase "go away" here is used in the sense customary among scientists. To destroy a new…
I remember a talk that Von Neumann gave at Princeton around 1950, describing the glorious future which he then saw for his computers. Most of the people that he hired for his computer project in the early days were meteorologists. Meteorology was the big thing on his horizon. He said, as soon as we have good…
If, on the other hand, we live in an open universe, infinite in space and time and continuing to expand into a future without end, then life has to face a prospect of slow freezing {111} rather than quick frying. The universe grows constantly colder as it expands, and the supply of free energy is constantly dwindling…
Bacteria could be the answer to the vampire. Everything seemed to flood over him then. It was as though he’d been the little Dutch boy with his finger in the dike, refusing to let the sea of reason in. There he’d been, crouching and content with his iron-bound theory. Now he’d straightened up and taken his finger out…
In Munich he walked. The air was warm and clean; it cleared some of the fumes from his head. He walked the brightly lighted slidewalks, adding his own pace to their ten-miles-per-hour speed. It occurred to him then that every city in the world had slidewalks, and that they all moved at ten miles per hour. The thought…
"Projections are essential for giving us information on long-term trends, but the timescale is beyond what many policy makers (and the public) consider to be relevant to their decision-making processes. Climate forecasts seek to address this issue by providing information on a shorter term (decadal) that can be used…
