Featured Article: Geologic time scale

The geologic time scale is used by geologists and other scientists to map the timing and relationships between events that have occurred during the history of the Earth.

Based on radiometric dating techniques, the Earth is estimated to be about 4,570 million years (4570 "Ma") old. The geological time scale is a means of mapping the history of the earth. It combines estimates of the age of geological formations as provided by radiometric dating techniques with the direct evidence of sequences and events in the rock record as assembled by geologists. In this way the geologic or deep time of Earth's past can be organized into various units according to events that took place in each period. Different spans of time on the time scale are usually delimited by major geologic or paleontologic events, such as mass extinctions. For example, the boundary between the Cretaceous period and the Palaeogene period is defined by the extinction event that marked the demise of the dinosaurs and of many marine species.

The earth history mapped on the geologic time scale contrasts with that mapped by young-earth creationists, which see the earth as only thousands of years old.

Popular Article: Anti-Semitism

Racial anti-Semitic caricature (France, 1898)
Anti-Semitism (alternatively spelled antisemitism) is hostility toward or prejudice against Jews as a religious, ethnic, or racial group, which can range from individual hatred to institutionalized, violent persecution. Anti-Semitism has a long history, extending back to the Greco-Roman world and culminating in the Nazi Holocaust. Before the nineteenth century, most anti-Semitism was religiously motivated, based on oft-repeated Christian allegations that the Jews had killed Jesus, and that their refusal to accept Jesus as the Messiah made them reprobates who deserved second-class status. Judaism was the only large religious minority after Christianity became the official religion of Europe and so suffered from discriminatory legislation, persecution and violence. Religious anti-Semitism (sometimes called anti-Judaism) usually did not affect those of Jewish ancestry who had converted to another religion—the Spanish Inquisition being the notable exception.

The dominant form of anti-Semitism from the nineteenth century until today has been racial anti-Semitism. With its origins in the cultural anthropological ideas of race that started during the Enlightenment, racial anti-Semitism focused on Jews as a racially distinct group, regardless of their religious practice, viewing them as sub-human and worthy of animosity. With the rise of racial anti-Semitism, conspiracy theories about Jewish plots in which Jews were acting in concert to dominate the world became a popular form of anti-Semitic expression. The highly explicit ideology of Adolf Hitler's Nazism was the most extreme example of this phenomenon, leading to the genocide of European Jewry called the Holocaust.
