Three maps should be provided, either in separate rooms or separated from each other by screens: one for each player, and one in the centre for the Umpire.* Each Commander and his subordinates will be allowed access only to their own map, the Umpire and his assistants moving from one side to the other. [...] Whenever…
The histo ry o f flying is a goo d example to loo k at in detail fo r insight into the interactio n o f techno lo gy with human affairs, because two radically different techno logies were co mpeting fo r survival- in the beginning they were called heavier-than-air and lighter-than-air. The airplane and the airship…
It also suggests, at least to me, that creativity can be enhanced deliberately through environmental variation. Two techniques seem promising: varying what you learn and varying where you learn it. I try each week to read a scientific paper in a field new to me—and to read it in a different place. New associations…
The atoms like each other to different degrees. Oxygen, for instance in the air, would like to be next to carbon, and if they get near to each other, they snap together. If they’re not too close though, they repel and they go apart, so they don’t know that they could snap together. It’s just as if you had a ball, it…
LAW I. Every body perseveres in its state of rest, or of uniform motion in a right line, unless it is compelled to change that state by forces impressed thereon. Projectiles persevere in their motions, so far as they are not retarded by the resistance of the air, or impelled downwards by the force of gravity. A top…
In its earliest development knowledge is self-sown. Impressions force themselves upon men’s senses whether they will or not, and often against their will. The amount of interest in which these impressions awaken is determined by the coarser pains and pleasures which they carry in their train or by mere curiosity; and…
[The octopus has] an amazing skin, because there are up to 20 million of these chromatophore pigment cells and to control 20 million of anything is going to take a lot of processing power. ... These animals have extraordinarily large, complicated brains to make all this work. ... And what does this mean about the…
By blending water and minerals from below with sunlight and CO2 from above, green plants link the earth to the sky. We tend to believe that plants grow out of the soil, but in fact most of their substance comes from the air. The bulk of the cellulose and the other organic compounds produced through photosynthesis…
Consider the eighth category, which deals with stones. Wilkins divides them into the following classifications: ordinary (flint, gravel, slate); intermediate (marble, amber, coral); precious (pearl, opal); transparent (amethyst, sapphire); and insoluble (coal, clay, and arsenic). The ninth category is almost as…
In a bravura passage, Darwin also considers Herschel’s disturbing suggestion that the entire cosmos may eventually wither back into ‘one dark centre’. This implies that the universe not only had a beginning, but will have a physically destructive end, a ‘Big Crunch’. There are hints here too of Milton’s vision of the…
1. Gravity. This is the weakest of the four, but it is a long-range force and acts on everything in the universe as an attraction. This means that for large bodies the gravitational forces all add up and can dominate over all other forces. 2. Electromagnetism. This is also long-range and is much stronger than gravity…
The glib words of years past from our politicians are hollow nightmares indeed when we are confronted with the staggering realities of what has to be done. But the key is there--technology, using it-and we hardly do now. The future may be unpredictable, but we can make a few well-aimed guesses about what life will be…
Botany is a branch of Natural History that possesses many advantages; it contributes to health of body and cheerfulness of disposition, by presenting an inducement to take air and exercise; it is adapted to the simplest capacity, and the objects of its investigation offer themselves without expense or difficulty…
The world looks so different after learning science. For example, the trees are made of air, primarily. When they are burned, they go back to air, and in the flaming heat is relased the flaming heat of the sun which was bound in to convert the air into trees, and in the ash is the small remnant of the part which did…
Turns out that a lot of the things that have happened in the lest than two years of this administration are the biggest or first or most important in generations. On the occasion of the Wall Street Reform announcement today, Tagan Godard at CQ politics wrote "Not since FDR has a president done so much to transform…
