Discusses the author's own experience with learning, teaching, and research study in chemistry. Indicates that one should take his working experience as a learning process to alleviate the reactive character of his earlier strongly held views. (CC)

Describes a recently developed technique for the rapid and simple detection of organophosphorus inhibitors in water using paper impregnated with cholinesterase. (JR)

Discusses research activities conducted by scientists from the United State of America, Canada, and the United Kingdom to determine the long-term effects on natural marine ecosystems, especially plankton communities, of such pollutants as heavy metals, synthetic hydrocarbons, and petroleum hydrocarbons. (CC)

Studied the effectiveness of using voluntary or mandatory quiz sections and specific quiz section leaders in teaching of large chemistry courses. Concluded that both exam and quiz should be retained in the course, but the value of mandatory quiz section attendance is doubtful. (CC)

Outlines a physical chemistry course which is designed for civil engineering juniors and seniors to solve environmental problems. (CC)

Describes the principles and uses of thermoluminescence technique in dating of pottery and ceramic pieces and establishing the authenticity of artifacts. (CC)

Presents a topical outline for physical chemistry suitable for training both chemistry majors and nonmajors. Suggests that an additional semester beyond the two semester sequence is essential for chemistry majors to achieve the course objectives. (CC)
