Paris, 9 June 2011 Why is Mars, the planet closest to us, ten times less massive than the Earth? This question remained unanswered for a long time, since it was extremely difficult to reproduce the mass of Mars in simulations. In 2009, recent progress in this field enabled Brad Hansen, an American researcher, to propos...

We wondered what a derivative is. Imagine you have a graph with temperature on the y-axis and x on the x-axis. If you pick two points on the graph you can calculate the difference in their y values and the difference in their x values. Dividing those, you would get ΔT/Δx. In the top-left graph we pick two points far ap...
Josephus clearly identifies the queen who visited Solomon as “the woman who ruled Egypt and Ethiopia,” and tells us that her name was Nikaulis. Yet the Bible calls her the Queen of Sheba (I Kg. 10; II Chr. 9). However, elsewhere in Josephus’ Antiquities, he identifies Saba (Sheba) as the Ethiopian capital. He writes “S...

When Were the Sun, Moon, and Stars Created? At first glance, this seems like an easy question. Just as children have been singing for generations, it was on day four when God made “the Sun, Moon, and stars galore.” Some, however, have alleged that the “sun, moon and stars were created ‘in the beginning’ (Gen. 1:1)” (Th...
