Four years later, general relativity made Einstein himself a celebrity. If gravity curves space, he had realized early on, a light beam passing near a massive object (say, the sun) would be deflected from its course. That deflection would shift the apparent position of the source of the light (say, a distant star).
Median sunscreen price was US$1.70 per 10 g. Assuming that standard sunscreen application recommendations (2 mg/cm 2) were followed, the median cost to the family varied from $178.20 per week (if children were 2-year-olds) to $238.40 per week (if children were 10-year-olds).ltraviolet (UV) radiation is a known carcinogen and sun-protection strategies, including sunscreen use, have long been advocated.
