Problem: In March 1861, Victoria's mother died, with Victoria at her side. Through reading her mother's papers, Victoria discovered that her mother had loved her deeply; she was heart-broken, and blamed Conroy and Lehzen for "wickedly" estranging her from her mother. To relieve his wife during her intense and deep grief, Albert took on most of her duties, despite being ill himself with chronic stomach trouble. In August, Victoria and Albert visited their son, the Prince of Wales, who was attending army manoeuvres near Dublin, and spent a few days holidaying in Killarney. In November, Albert was made aware of gossip that his son had slept with an actress in Ireland. Appalled, Albert travelled to Cambridge, where his son was studying, to confront him. By the beginning of December, Albert was very unwell. He was diagnosed with typhoid fever by William Jenner, and died on 14 December 1861. Victoria was devastated. She blamed her husband's death on worry over the Prince of Wales's philandering. He had been "killed by that dreadful business", she said. She entered a state of mourning and wore black for the remainder of her life. She avoided public appearances, and rarely set foot in London in the following years. Her seclusion earned her the nickname "widow of Windsor".
What year did Victoria's mother die?

Problem: The most accurate timekeeping devices are atomic clocks, which are accurate to seconds in many millions of years, and are used to calibrate other clocks and timekeeping instruments. Atomic clocks use the frequency of electronic transitions in certain atoms to measure the second. One of the most common atoms used is caesium, most modern atomic clocks probe caesium with microwaves to determine the frequency of these electron vibrations. Since 1967, the International System of Measurements bases its unit of time, the second, on the properties of caesium atoms. SI defines the second as 9,192,631,770 cycles of the radiation that corresponds to the transition between two electron spin energy levels of the ground state of the 133Cs atom.
Which timekeeping devices are the least accurate?

Problem: In France, offshoots of Cubism developed, including Orphism, Abstract art and later Purism. In other countries Futurism, Suprematism, Dada, Constructivism and De Stijl developed in response to Cubism. Early Futurist paintings hold in common with Cubism the fusing of the past and the present, the representation of different views of the subject pictured at the same time, also called multiple perspective, simultaneity or multiplicity, while Constructivism was influenced by Picasso's technique of constructing sculpture from separate elements. Other common threads between these disparate movements include the faceting or simplification of geometric forms, and the association of mechanization and modern life.
What were the three offshoots of Cubism formed in France?
