It is regrettable that the inquiry into the fundamental question of origins has degenerated to such an emotional level. Attitudes must be improved, and efforts now devoted to name-calling should be redirected towards good scholarship. Published in Origins v. 10, n. 2.

A period of unusual cold in the Northern Hemisphere extended from about 1450 to around 1850, known as the Little Ice Age. The causes are not well understood, but could have included variation in solar output and/or volcanic activity. Published in Origins v. 10, n. 2.

Some rocks show magnetic properties that align with the present geomagnetic field, while others show a reverse alignment. This is taken to indicate that the earth's geomagnetic field has reversed many times during earth history. Patterns of magnetic alignment have been used to correlate geologic layers and to support the concept of plate tectonics. Much remains to be understood concerning the causes and rates of magnetic reversals. Published in Origins v. 10, n. 2.

Radioisotope ages are calculated from ratios of certain atoms. The isotopic ratios can be precisely measured, but the calculation of age from that ratio involves assumptions that may vary depending on the philosophical orientation of the investigator. Published in Origins v. 10, n. 2.

A review of two books on the origin of life: Life Itself, and Evolution from Space. Both books conclude that life is much too complex to have originated on the earth, and must have come from some other part of the universe. Published in Origins v. 10, n. 2.
