The discovery and isolation of radium in uranium ore (pitchblende) by Marie Curie sparked the development of uranium mining to extract the radium, which was used to make glow-in-the-dark paints for clock and aircraft dials. This left a prodigious quantity of uranium as a waste product, since it takes three tonnes of uranium to extract one gram of radium. This waste product was diverted to the glazing industry, making uranium glazes very inexpensive and abundant. Besides the pottery glazes, uranium tile glazes accounted for the bulk of the use, including common bathroom and kitchen tiles which can be produced in green, yellow, mauve, black, blue, red and other colors.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): Who isolated radium in uranium core?
Ah, so.. unanswerable

After Christianization, the Roman Catholic Church and local rulers led German expansion and settlement in areas inhabited by Slavs and Balts, known as Ostsiedlung. During the wars waged in the Baltic by the Catholic German Teutonic Knights; the lands inhabited by the ethnic group of the Old Prussians (the current reference to the people known then simply as the "Prussians"), were conquered by the Germans. The Old Prussians were an ethnic group related to the Latvian and Lithuanian Baltic peoples. The former German state of Prussia took its name from the Baltic Prussians, although it was led by Germans who had assimilated the Old Prussians; the old Prussian language was extinct by the 17th or early 18th century. The Slavic people of the Teutonic-controlled Baltic were assimilated into German culture and eventually there were many intermarriages of Slavic and German families, including amongst the Prussia's aristocracy known as the Junkers. Prussian military strategist Karl von Clausewitz is a famous German whose surname is of Slavic origin. Massive German settlement led to the assimilation of Baltic (Old Prussians) and Slavic (Wends) populations, who were exhausted by previous warfare.

Ah, so.. Latvian and Lithuanian Baltic peoples

Sixteen was held to be the minimum permissible age in the 1988 Supreme Court decision of Thompson v. Oklahoma. The Court, considering the case Roper v. Simmons in March 2005, found the execution of juvenile offenders unconstitutional by a 54 margin, effectively raising the minimum permissible age to 18. State laws have not been updated to conform with this decision. In the American legal system, unconstitutional laws do not need to be repealed; instead, they are held to be unenforceable. (See also List of juvenile offenders executed in the United States)
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): According to Thompson v. Oklahoma, what was the oldest age at which a person might be executed?
Ah, so..
unanswerable
