  • Dramatic progress has been made in all branches of physics since the National Research Council's 1986 decadal survey of the field. The Physics in a New Era series explores these advances and looks ahead to future goals. The series includes assessments of the major subfields and reports on several smaller subfields, and preparation has begun on an overview volume on the unity of physics, its relationships to other fields, and its contributions to national needs.

  • Astronomy is the most ancient science humans have practiced on Earth. It is a science of extremes and of large numbers: extremes of time – from the big bang to infinity –, of distances, of temperatures, of density and masses, of magnetic field, etc.

  • The coexisting systemof VOCs is complex. A small change in environmental conditions (e.g., temperature) may result in changes on VOC concentrations, and also some VOCs may be involved in chemical reactions during the trans- portation. Meanwhile, as a consequence of high density of petroleumrefineries, synthetic organic chemical plants, and variousmobile sources, the formation rate and concentration of ozone in theHouston area are extremely high, and propene becomes a dominant reactive hydrocarbon (20).

  • Water quality. Water draining off newly graded surfaces and roads or oil or water accidentally discharged during oil and gas production can increase the amount of sediment, salt, and pollutants discharged into rivers and streams, thereby degrading them. In addition, shallow aquifers can be polluted if required protective measures are not in place, and the production of methane gas from coal beds can deplete shallow aquifers that serve as domestic water sources. 6 Habitat.
