Observations of 23 transits of Mercury in front of the sun between 1736 and 1973 show no indication of any significant change in the diameter of the sun. Regression analysis yields a decrease of the angular diameter, as viewed from the earth, of under 0.3 arc second per century (> 90 percent confidence limit).

It is more than a century since what we call the ‘history of religions’ was discovered and has been studied. But only recently have we realized that the ‘geography of religions’ is just as important. East and West are essential geopolitical categories, determined by cultural, historical and even religious differences: an Indian and a Swedish Catholic ...

Sunlight is the main environmental factor influencing human skin. The sun-light’s terrestrial spectrum is different from the extraterrestrial one, sunlight being changed by the filter effect of ozone and particles in the stratosphere and atmosphere. Attention is drawn to the influence of ‘supersonic transporters’ (SST) and chlorofluoromethanes on this ...
