Thus the radio elements formed strange and cruel families in which each member was created by spontaneous transformation of the mother substance: radium was a “descendant” of uranium, polonium a descendant of radium.
If we examine the accomplishments of man in his most advanced endeavors, in theory and in practice, we find that the cell has done all this long before him, with greater resourcefulness and much greater efficiency.
BRAIN, n. An apparatus with which we think that we think. That which distinguishes the man who is content to be something from the man who wishes to do something. A man of great wealth, or one who has been pitchforked into high station, has commonly such a headful of brain that his neighbors cannot keep their hats on…
One way of dealing with errors is to have friends who are willing to spend the time necessary to carry out a critical examination of the experimental design beforehand and the results after the experiments have been completed. An even better way is to have an enemy. An enemy is willing to devote a vast amount of time…
(Found in the trap where he had been confined all night by Dr. Priestley, for the sake of making experiments with different kinds of air.) OH! hear a pensive prisoner's prayer, For liberty that sighs; And never let thine heart be shut Against the prisoner's cries! For here forlorn and sad I sit, Within the wiry grate…
In the beginning was the word WORD WORE GORE GONE GENE and by the mutations came the gene.
The dog [in Pavlov's experiments] does not continue to salivate whenever it hears a bell unless sometimes at least an edible offering accompanies the bell. But there are innumerable instances in human life where a single association, never reinforced, results in the establishment of a life-long dynamic system. An…
I like to remember the distinguished Swedish oceanographer, Otto Pettersson, who died a few years ago at the age of ninety-three, in full possession of his keen mental powers. His son has related in a recent book how intensely his father enjoyed every new experience, every new discovery concerning the world about him…
Williams’s experiments have shown that the offspring of mice who ingest a phytochemical derived from cruciferous vegetables like broccoli, cabbage, and brussels sprouts during pregnancy were much less likely to get cancer, even when exposed to a known carcinogen. The same is true of the offspring of mice who were…
"Die? Can a machine die?" "I can cease to exist, sir. Call it by whatever word you wish. I am old. Not one sentient being in the Galaxy that was alive when I was first given consciousness is still alive today; nothing organic; nothing robotic. Even I myself lack continuity." "In what way?" "There is no physical part…
A favourite example, ever since it was pointed out to me by Professor J. D. Currey when he tutored me as an undergraduate, is the recurrent laryngeal nerve.* It is a branch of one of the cranial nerves, those nerves that lead directly from the brain rather than from the spinal cord. One of the cranial nerves, the…
But there's something more: the Harvest Moon Festival is an important holiday in traditional Chinese communities in America. In the week preceding the festival, the death rate in the community is found to fall by 35 per cent. In the following week the death rate jumps by 35 per cent. Control groups of non-Chinese show…
A common way anecdotal evidence becomes unscientific is through fallacious reasoning such as the Post hoc ergo propter hoc fallacy, the human tendency to assume that if one event happens after another, then the first must be the cause of the second. Another fallacy involvesinductive reasoning. For instance, if an…
A Circle round divided in four parts Hath been great Study 'mongst the men of Arts; Since Archimed's or Euclid's time, each Brain Hath on a Line been stretched, yet all in Vain; And every Thought hath been a Figure set, Doubts Cyphers were, Hopes as Triangles met; There was Division and Subtraction made, And Lines…
It is clearly not easy for man to give up the satisfaction of this inclination to aggression. They do not feel comfortable without it. The advantage which a comparatively small cultural group offers of allowing this instinct an outlet in the form of hostility against intruders is not to be despised. It is always…
The genes of cellular cooperation that evolved with multicellularity about a billion years ago are the same genes that malfunction to cause cancer. We hypothesize that cancer is an atavistic condition that occurs when genetic or epigenetic malfunction unlocks an ancient 'toolkit' of pre-existing adaptations…
Consider, for example, the fact that the size of military units has not changed materially in thousands of years, even though our communication technology (from signal fires to telegraphy to radio to radar) has. The basic unit in the Roman army (the “maniple”) was composed of 120-130 men, and the size of the analogous…
