The dry lands of Namibia were inhabited since early times by San, Damara, and Namaqua, and since about the 14th century AD by immigrating Bantu who came with the Bantu expansion. Most of the territory became a German Imperial protectorate in 1884 and remained a German colony until the end of World War I. In 1920, the League of Nations mandated the country to South Africa, which imposed its laws and, from 1948, its apartheid policy. The port of Walvis Bay and the offshore Penguin Islands had been annexed by the Cape Colony under the British crown by 1878 and had become an integral part of the new Union of South Africa at its creation in 1910.
When did South Africa impose the apartheid policy on Namibia?
****
The answer: 1948

Jonathan Israel called the journals the most influential cultural innovation of European intellectual culture. They shifted the attention of the "cultivated public" away from established authorities to novelty and innovation, and promoted the "enlightened" ideals of toleration and intellectual objectivity.

In the last years of the nineteenth century, Planck was investigating the problem of black-body radiation first posed by Kirchhoff some forty years earlier. It is well known that hot objects glow, and that hotter objects glow brighter than cooler ones. The electromagnetic field obeys laws of motion similarly to a mass on a spring, and can come to thermal equilibrium with hot atoms. The hot object in equilibrium with light absorbs just as much light as it emits. If the object is black, meaning it absorbs all the light that hits it, then its thermal light emission is maximized.
What type of radiation was Planck studying in the late 19th century?
****
The answer:
black-body
