71. Pterodactyls in the Mesozoic: A Flap in Time [Aeon Journal $]
... Bob Giuiliani.) The science of paleontology often goes hand-in-hand with geology to define the periods in which fossils are found. Occasionally, too, chemistry is involved, as when chemist Walter Alvarez and his colleagues at UC Berkeley investigated a thin rock layer near Gubbio, Italy, and, along with his Nobel-laureate father, Luis Alvarez, unexpectedly found what is ... Ends Pterodactylus. (Illustration by Bob Giuiliani.) The science of paleontology often goes hand-in-hand with geology to define the periods in which fossils are found.

And, there is at least one other mechanism. As mentioned in another essay, [21 an increased presence and concentration of carbon dioxide chemically accelerates the cementing process on alluvial sediments without the addition of much heat and pressure. This CO 2 would most likely have come from volcanic outgassing or other venting, and of ...

... decide which of these time capsules to open." Sashimi appears dustier than Adirondack. The dust layer could obscure good observations of the rock's surface, which may give information about chemical changes and other weathering from environmental conditions affecting the rock since its surface was fresh. Also, Sashimi is more pitted than Adirondack. That makes it a poorer candidate for the ... and from this data we can derive the elemental composition of martian soils and rocks," said Dr. Johannes Brueckner, rover science team member from the Max Planck Institute for Chemistry, Mainz, Germany. The instrument found the most prevalent elements in the soil patch were silicon and iron. It also found significant levels of chlorine and sulfur, characteristic of ... on an early Mars that had a thicker atmosphere and a warmer climate. If true, large quantities of carbon dioxide should have dissolved out of Mars1s atmosphere into the water and chemically reacted with other materials to form carbonates. But orbital data from Mars Global Surveyor's instrument reveal much lower carbonate abundances than predicted. [From SkyandTelescope.com THORNHILL COMMENTS: Spirit has found ...

... , erroneously, to meteoric impacts.____ GRAVITY IS THE PROBLEM: UNDERSTANDING IT IS THE SOLUTION. The space shuttle is a technological marvel that must harness brute chemical and aerodynamic forces in order to overcome the weak force of gravity. The reason for such an approach is that we do not understand gravity. When we finally understand it, ... seems the clue about the true nature of gravity has been available to chemists? who are not interested in gravity? and unavailable to physicists? who are not interested in physical chemistry (and view the world through Einstein's distorting spectacles). Look at any average general physics textbook and you will find no reference to Van der Waals' or London forces. ... puzzling distinction between gravity and the powerful electromagnetic forces, which may repel as well as attract.

... complex phenomena can be reduced to less complex ones; for example, in biology, it is the belief that all the phenomena of life can ultimately be understood in terms of chemistry and physics. Holism is the doctrine that wholes are more than the sum of their parts. A cell, for example, divides randomly, this indeterminism occurring at all levels ... db=default&uid=default &id=43&ww=1&full=1&view_records=1 Rupert suggest that genes are responsible for making proteins and chemicals, etc., but not for the particular form taken by individual cells. As an analogy, he said that if you remove a transistor from a TV set, the ... is due to their being microscopic crystals contaminating future crystalisations; but this often happens in new laboratories (where it is suggested that the crystal contamination is carried on the beards of chemists!). Additional, new crystalisations should be more stable that much older ones, so one would expect their melting points to increase over time. Rupert researched a series of ...

... impact in Canada. If they survived the passage, so could other complex molecules. Meanwhile, deep in the Earth, bacteria have been found which survive on hydrogen produced in chemical reactions between water and rock. They seem to be closely related even though thousands of miles apart. Hoyle and Gold continue to be vindicated. As we have reported before, ... p. 6, 107, Sep-Oct 96, p. 6, 108, Nov-Dec 96, p. 6 The classic experiment in which electricity was discharged through a mixture of chemicals thought to be present on early Earth and resulted in amino acids, the building blocks of life, did not convince everyone as Earth was supposedly hydrogen starved. An alternative view ... capable of containing genetic material, although microorganisms on Earth live in some strange places and some are almost as small, though those which produce magnetite crystals are much larger. Some chemists say the temperature necessary to form the carbonate globules was far too high to allow life. By the end of the year further studies argued against the structures being microfossils.

77. Has The Second Law Been Repealed? [Science Frontiers Website]
... the largest to the smallest scales, the universe is evolving. Matter, in the form of galaxies, is undergoing a colossal expansion. Gas, condensed into stars, is radiating thermonuclear energy out across an infall of matter, drawn by gravity. The simplest of chemical reactions and the most complex of biological activities are occurring on the surface of the earth in a state far from equilibrium; they are heated by the sun and cooled by the vacuum of space. This pervasive cosmic imbalance is the driving force in producing an environment ... . Finally, the patterns decay and the system dies, as secondary reactions drain the flow of the primary reaction." From this starting point, the implication is made that all manner of biological "reactions" are analogous and therefore reducible to nought but physics and chemistry. Some examples given of self-organizing biological phenomena are: (1) the sequencing of amino acids into selfreplicating structures; (2) slime-mold organization; and (3) the origin of the lens structure of the firefly. All of these claims are accompanied by ...

... Science Frontiers ONLINE No. 48: Nov-Dec 1986 Issue Contents Other pages Home Page Science Frontiers Online All Issues This Issue Sourcebook Project Sourcebook Subjects The Cosmic Chemistry Of Life C. Ponnamperuma, at the University of Maryland, speculates that the genetic code employed by earth life may, in fact, reflect a universal chemistry. His lab data "suggest that the formation and linking of life's building blocks-- amino acids and nucleotides-- may have been all but inevitable, given the starting chemistry of earth's 'primordial soup.' ... Going even further Ponnamperuma believes that "if there is life elsewhere in the universe, chemically speaking it would be very similar to what we have on earth."

... From: Pensée Vol. 3 No 3: (Fall 1973) "Immanuel Velikovsky Reconsidered V" Home¦ Issue Contents Velikovsky And The Media Chemical and Engineering News Industrial Research Analog Medical Tribune When, in 1950, Velikovsky's Worlds in Collision became a bestseller, academia seemed to lose its self-control. The scientific community, especially, directed a withering and nearly hysterical scorn at the gullibility of the media and the public for taking seriously such unscientific nonsense. While thousands of reviews of the book were being written and while the public ... ," while a third complained (without giving details) that "Velikovsky's ideas are too haywire to be useful" in stimulating new thought. RARA AVIS The March, 1973, issue of Industrial Research featured a five-page spread on "Velikovsky." Written by California chemist and Pensee contributor, Fred Jueneman, the article served as an engaging introduction to Velikovsky and his views.

... Science Frontiers ONLINE No. 92: Mar-Apr 1994 Issue Contents Other pages Home Page Science Frontiers Online All Issues This Issue Sourcebook Project Sourcebook Subjects The World Before Our World Genetically speaking, modern terrestrial life is bilingual in the sense that it employs two chemical languages. Function is written in the 20 amino-acid "alphabet" of proteins, while information is conveyed in sequences of four nucleotide "letters" called codons. We need go no further with the genetics lesson because our purpose here is to speculate a bit about the monolingual world ... have preceded ours. This older world is commonly termed the "RNA World." It was and is monolingual because both function and information are carried on a single molecule. It is customary to call the RNA World "prebiotic," meaning that it was all chemistry and no life. But, one does wonder whether that was all there was to it. Catalysis and replication of genetic information occurred in the RNA World. What besides a chemical soup might have existed before "life-as-we-know-it" arrived upon the scene? A science ...
