Earth's atmosphere before the age of dinosaurs

Article Abstract:

Earth's atmosphere in the time before dinosaurs is discussed by a professor emeritus of chemical engineering, Oregon State Univ., a senior scientist in the space tech. div. of TRW, and an astronaut, mission specialist, NASA. Three alternatives are suggested. Topics include the earth's surface, its original atmosphere, the reaction of carbon dioxide with upwelling minerals, dissolution of carbon dioxide in oceans, the astronomical argument, limestone caves, plant growth at high carbon dioxide concentrations, experimental verification, and comparison of Venus with earth.

Earth's early atmosphere

Article Abstract:

Evidence from biology and aerodynamic theory show that the atmosphere at the time of the dinosaurs must have been significantly more dense and at much higher pressure than it is today. Topics include the quetzalcoatlus anomaly. The pteranodon, a flying animal, would have been living a very difficult life if air had had the density it has today. Prehistoric fliers do not correlate with modern birds in terms of the mass/wing-loading ratio. The ratios for the two aforementioned are apparently consistent with an atmospheric pressure of about 4-5 bar.

Catalytic kinetics and elephant curves

Article Abstract:

This article touches upon the Langmuir-Hinshelwood-Hougen-Watson model and relates it to the animal functions in mathematics in a lighter vein.
