... . Let us begin with his abstract: "There are several hints in physics of a domain of external reality transcendent to three-dimensional space and time. This paper calls attention to several of these intimations of a real world beyond the natural order. Examples are the complex state functions in configuration space of quantum mechanics, the singularity at the birth of the universe, the anthropic principle, the role of chance in evolution, and the unaccountable fruit fulness of mathematics for physics. None of these examples touch on the existence or activity of God, but they do suggest that external reality may be much richer than the natural world which it is the task of physics to describe." Pollard then elaborates: Example 1. Quantum mechanics, a mathematical formulation of reality, has been extraordinarily successful ... describing and predicting many things in the microscopic world. Pollard notes that quantum mechanics contains no hint of God per se and possesses no numinous quality, but its great complexity and multidimensionality provide evidence for "the reality of the transcendent order in which the natural universe is embedded." Example 2. The singularity at the beginning of the universe. Science is at a loss to explain creation and what happened before. (Pollard assumes that creation occurred like most scientists.) Example 3. The anthropic principle can be interpreted as a restatement of the religious contention that the universe was made-for-humankind. In Pollard's words: "If one imagines an ensemble of universes of different size and duration and equipped with different values of the fundamental constants G, h, c, e ...

... stalagmites are created by dripping water that is charged with minerals, calcium carbonate in particular. That stalactites contain crystals of calcite is not denied in the Science et Vie article. Indeed, an electron micro scope photograph shows them clearly; but it also shows that a web of mineralized bacteria is also an intergral part of the stalactite's structure. Laboratory simulations have shown that microorganisms take an active role in the process of mineralization. (Dupont, George; "Et Si les Stalactites Etaient Vivantes?" Science et Vie , p. 86, August 1987. Cr. C. Mauge.) Besides being a surprising adjustment of our ideas about stalactite growth, the recognition that microorganisms may play an active role in the subterranean world stimulates two new questions: (1 ) Can we believe ... an immensely greater continuum of cracks, crevices, channels, and pores which circulate air, water, and chemicals in solution. This "crevicular structure" may be continuous for thousands of miles, possibly around the world. Furthermore, it is filled with life forms of great variety, usually blind, and usually related to creatures of the light. A recent article in American Scientist focuses on the evolution of the larger forms of subterranean life, especially the amphipods. Interestingly enough, it doesn't even mention micro-organisms.

... is popularly thought to have but a single purpose -- fertilization of the egg. This is not so! "Nonfertilizing sperm with special morphologies have long been known to exist in invertebrates. Until recently, abnormal sperm in mammals were considered errors in production. Now, however, Baker and Bellis have proposed that mammalian sperm, like some invertebrate sperm are polymorphic and adapted to a variety of nonfertilizing roles in sperm competition, including prevention of passage of sperm inseminated by another male. More specifically, their 'kamikaze' hypothesis proposes that deformed mammalian sperm are adapted to fa cilitate the formation and functioning of copulatory plugs." The author of the present paper, A. H. Harcourt, thinks that although some 20% of mammalian sperm, on the average, is abnormal (two heard ... no heads, two tails, no tails, coiled tails, etc.) such sperm represents only errors on the assembly line. These abnormal sperm have no special purpose, at least in mammals. (Harcourt, A.H .; "Sperm Competition and the Evolution of Nonfertilizing Sperm in Mammals," Evolution , 45:314, 1991.) Comment. Even if mammals haven't yet developed kamikaze sperm, some animals have; and one must wonder exactly how multipurpose sperm (and ova, too) evolved. For a copulatory plug to be effective, large numbers of mutant sperm with special plugging properties and knowing just where to go, would have to be generated all at once. That would seem to require a lot of chance mutations all at once! The " ...

... spermatozoa often cannot find an egg of the correct species. They may then fertilize eggs of a distantly related species. In such "wide hybrids," the larvae may resemble one parent and the adults the other. There is much more. The gist of it all is that evolution has been much more than random mutation and natural selection. Hybridization and outright mergers (endosymbiosis) have played important roles. Even our own cells harbor mitochondria that have their own DNA. They are probably bacterial invaders that long ago settled down in the cells of our ancestors.

... the fertile fields of outer space. "Fertile?" Yes, outer space is a vast biochemical retort. D. Brownlee, R. Walker, and others: ". .. suggest that interplanetary dust has probably carried organic matter to Earth since the early aeons of the solar system. The complexity of the organic molecules found on these particles has fueled the imaginations of many who ponder the role extraterrestrial matter may have played in the prebiological evolution of organic material on the primordial Earth." Beyond these conjectures, several other things about interplanetary dust particles bother scientists: "' What is surprising,' Walker notes, 'and still not understood, is the fact that the organic molecules we see in the dust particles are different from those previously seen in meteorites.' Another enigma is ... observation of striking isotopic anomalies -- large enrichments of deuterium relative to hydrogen, as much as ten times greater than one sees in terrestrial samples -- in the particles in which Zare's group observed the organic molecules." Yes, the original dust of life may have been extraterrestrial. (Zeman, Ellen J.; "Complex Organic Molecules Found in Interplanetary Dust Particles," Physics Today, 47:17, March 1991.) Comment.

... Sourcebook Subjects Chaotic Dynamics In The Solar System The following abstract appeared in a 1988 issue of Eos, a weekly publication of the American Geophysical Union. "Newton's equations have chaotic solutions as well as regular solutions. The solar system is generally perceived as evolving with clockwork regularity, yet there are several physical situations in the solar system where chaotic solutions of Newton's equations play an important role. There are physical examples of both chaotic rotation and chaotic orbital evolution. "Saturn's satellite Hyperion is currently tumbling chaotically, its rotation and spin axis orientation undergo significant irregular variations on a time scale of only a couple of orbit periods. Many other satellites in the solar system have had chaotic rotations in the past. It is not possible to tidally evolve into a synchronous rotation without ... through a chaotic zone. For irregularly shaped satellites this chaotic zone is attitude-unstable and chaotic tumbling ensues. This episode of chaotic tumbling probably lasts on the order of the tidal despinning timescale. For example, the Martian satellites Phobos and Deimos tumbled before they were captured into synchronous rotation for a time interval on the order of 10 million years and 100 million years, respectively. This episode of chaotic tumbling could have had a significant effect on the orbital histories of these satellites." Theis abstract continues, naming as other candidates for chaotic histories: some of the asteroids, Miranda (a satellite of Uranus), and the planet Pluto.

... and even (gasp!) mammals. This is, of course, reductionism in the extreme. But the successes with protein folding have led two New Zealand biochemists to speculate as follows: If it does turn out that a substantial amount of higher biological form is natural, then the implications will be radical and far-reaching. It will mean that physical laws must have had a far greater role in the evolution of biological form than is generally assumed. And it will mean a return to the pre-Darwinian conception that underlying all the diversity of life is a finite set of natural forms that will recur over and over again anywhere in the cosmos where there is carbon-based life.
