When Thomas Jefferson wrote: "I have sworn upon the altar of God eternal hostility against every form of tyranny over the mind of man,'' he clearly realized that most tyranny originates in the mind of man and in the basic conditions of human existence.

Some aspects of those basic conditions remain, so far, essentially unchanged - such as the short human lifespan. Others have been markedly changed by science, engineering, and increases in human knowledge. Even King Solomon was trapped in the boredom and vanity of repetition of works of agriculture and architecture little different (except in extent) from those of his predecessors. Today, ordinary scientists, engineers, and those who support and work with them can undertake projects that are entirely unique. The technological age has mobilized some of the best qualities of the human spirit by providing mankind with an endless frontier.

While each of us might categorize the properties of the human mind and spirit in different ways, most lists would include charity, love, faith, hope, inventiveness, reason, self-importance, greed, fear, jealousy, and envy among the fundamental properties of human beings. While science, engineering, and other technology are exact and rational, most human properties are not. A great modern challenge is to meld all of these human characteristics with technology for an ultimately positive result.

Jefferson and his colleagues understood that civil institutions can be formed in such a way as to encourage the positive characteristics of human beings and to discourage the negative characteristics. Each individual needs such institutions because each must struggle with these things within himself and others.

In the words of Aleksandr Solzhenitsyn, "Gradually it was disclosed to me that the line separating good and evil passes not through states, nor between classes, nor between political parties either - but right through every human heart, and through all human hearts. This line shifts. Inside us, it oscillates with the years. And even within hearts overwhelmed by evil, one small bridgehead of good is retained. And even in the best of all hearts, there remains . . . an unuprooted corner of evil.'' During the years that Laurelee and I traded commodities, we became very familiar with greed and fear. For example, about 100 times each year, short-term fluctuations in the copper market moved either upward or downward out of the usual range and triggered a reaction of greed or fear in many individual speculators. This reaction was partially predictable, so we were able to parameterize this phenomenon and use it for profitable trading. Fear is a stronger emotion than greed, so markets that reflect these emotions tend to fall faster than they rise. With our PDP-11 computers, she and I traded these fluctuations in copper from a room on our farm. On some days, we made about 1% of all trades in the world copper market. Today, technologists are seriously hampered by the growth of civil institutions that stimulate negative aspects of human nature. The government welfare industry is not just an institution that wastes resources. It is also an institution that has built a large underclass of people who are more than usually motivated by jealousy and envy.

The electric shaver "discovery'' involved the screening of large numbers of items until one was found for publicity. Without correction for the number of efforts to find a correlating item, the report is erroneous. Since thousands of pseudoscientists with lavish tax funding are searching for correlations between technology and evil, random chance is providing a plentiful supply of false correlation scare stories.

If another set of coins that had a larger number of coins were used, then the distribution would be shifted to the right. In this case, both distributions would be normal. Assuming this, a calculation of the probability that the two sets of coins are different can be made with high reliability after a relatively few experimental trials.

Suppose, however, that the two different sets of coins are used together in a single experiment. The result will be a broadened distribution function that is not normal. If the sets were different enough, the experiment would even show a distribution with two peaks with a shape like two overlapping bells. In this case, the variation is not due only to similarly sized independent variables. The difference in number introduces a variable much larger than the others that give rise to the variable outcomes of individual tosses of sets of coins.

In most instances of alleged ill effects of technology, there is insufficient data to prove that the measurements under study have a normal

distribution function. This is not surprising because most experiments involving living things or other environmental phenomena are relatively difficult to perform. This limits the number of observations. Powerful statistical tests are often needed to extract significance from small numbers of experimental measurements. These tests are more likely to give values indicating significance if they assume distribution function shape, so tax-financed experimenters much prefer them.

When distribution function shape is unknown, the proper approach is to use nonparametric statistics. There are simple non-parametric methods of which the most common is the Wilcoxon Test.

Suppose that we know the age at death of 10 men (and only ten men, since it is imperative to use all of the data without selection), five of whom were members of the Sierra Club. The control subjects died at ages 78, 81, 83, 85, and 88, while the Sierra Club members died at ages 73, 76, 79, 80, and 82. The distribution of these men in order of age at death is, therefore, S-S-C-S-S-C-S-C-C-C. Since we do not know the shape of the distribution functions, the Wilcoxon test simply assigns a rank to each individual of S1-S2-C3-S4-S5-C6-S7-C8-C9-C10. The sum of the ranks of the Sierra Club members is 1+2+4+5+7 = 19. The test then calculates, for the case of blindly choosing 10 objects, five of one label and five of another in succession, the probability of a set having a sum of ranks less than or equal to 19.< /FONT >

For our simple case, this can be done by actually listing all possibilities and counting them. In this case, P nc = 0.048, so there is a 95% chance that our experiment shows that Sierra club members do not live as long - providing there were no other systematic variables besides Club membership. There are, of course, other variables. For instance, those still clinging to Sierra Club membership in the 1990s, when it has allied itself with Greenpeace and Earth First and abandoned allegiance to its original goals, are likely to be people of below average wisdom. This may also shorten lifespan. Correlation does not prove causality.

Nevertheless, we have done our calculation properly without assuming a normal distribution when the data set is too small to check that assumption. For much larger sets of data, Wilcoxon calculations are more involved. See the above-referenced book by Alder and Roessler and also the Mech. Ag. Dev. article by Robinson and Robin-son for examples and references.

(This reminds me of the story of the conservative retired Iowa farmer who suddenly announced to his friends that he had joined the Communist party. "Why,'' they asked, "had he done such a dishonorable thing?'' "Well,'' he explained, "I have been to my doctor. He says that I have just six months to live. I figure it is better that one of them should die than one of us.'') Errors: Whenever possible, each quantitative scientific assertion should be accompanied by a quantitative estimate of its reliability or likely range of error. Where the error itself is an important part of the result, then the error of the error should also be calculated and reported. One sign of unreliable science is poor reporting of errors. Each scientist is obligated to estimate and report the reliability of his results.

With this accurate tool for measurement, we were able to distinguish between the then-popular theory of general anesthesia which depended only upon the lipid solubility of anesthetics and the microcrystal theory which depended in predictable ways upon the geometry of specific anesthetic molecules. The microcrystal theory, proposed independently by Miller and by Pauling, turned out to be correct.

Brine shrimp are not yet an endangered species, unlike scientists who work independently of government regulation and control.
