Question: Monastic reform inspired change in the secular church. The ideals that it was based upon were brought to the papacy by Pope Leo IX (pope 1049–1054), and provided the ideology of the clerical independence that led to the Investiture Controversy in the late 11th century. This involved Pope Gregory VII (pope 1073–85) and Emperor Henry IV, who initially clashed over episcopal appointments, a dispute that turned into a battle over the ideas of investiture, clerical marriage, and simony. The emperor saw the protection of the Church as one of his responsibilities as well as wanting to preserve the right to appoint his own choices as bishops within his lands, but the papacy insisted on the Church's independence from secular lords. These issues remained unresolved after the compromise of 1122 known as the Concordat of Worms. The dispute represents a significant stage in the creation of a papal monarchy separate from and equal to lay authorities. It also had the permanent consequence of empowering German princes at the expense of the German emperors.
Try to answer this question if possible: What pope was involved in the Investiture Controversy?
Answer: Pope Gregory VII
Question: Chopin's disease and the cause of his death have since been a matter of discussion. His death certificate gave the cause as tuberculosis, and his physician, Jean Cruveilhier, was then the leading French authority on this disease. Other possibilities have been advanced including cystic fibrosis, cirrhosis and alpha 1-antitrypsin deficiency. However, the attribution of tuberculosis as principal cause of death has not been disproved. Permission for DNA testing, which could put the matter to rest, has been denied by the Polish government.
Try to answer this question if possible: What was the cause of death on Chopin's death certificate?
Answer: tuberculosis
Question: The "Notre Dame Victory March" is the fight song for the University of Notre Dame. It was written by two brothers who were Notre Dame graduates. The Rev. Michael J. Shea, a 1904 graduate, wrote the music, and his brother, John F. Shea, who earned degrees in 1906 and 1908, wrote the original lyrics. The lyrics were revised in the 1920s; it first appeared under the copyright of the University of Notre Dame in 1928. The chorus is, "Cheer cheer for old Notre Dame, wake up the echos cheering her name. Send a volley cheer on high, shake down the thunder from the sky! What though the odds be great or small, old Notre Dame will win over all. While her loyal sons are marching, onward to victory!"
Try to answer this question if possible: In what year did Michael J. Shea graduate from Notre Dame?
Answer: 1904
Question: Vacuum is useful in a variety of processes and devices. Its first widespread use was in the incandescent light bulb to protect the filament from chemical degradation. The chemical inertness produced by a vacuum is also useful for electron beam welding, cold welding, vacuum packing and vacuum frying. Ultra-high vacuum is used in the study of atomically clean substrates, as only a very good vacuum preserves atomic-scale clean surfaces for a reasonably long time (on the order of minutes to days). High to ultra-high vacuum removes the obstruction of air, allowing particle beams to deposit or remove materials without contamination. This is the principle behind chemical vapor deposition, physical vapor deposition, and dry etching which are essential to the fabrication of semiconductors and optical coatings, and to surface science. The reduction of convection provides the thermal insulation of thermos bottles. Deep vacuum lowers the boiling point of liquids and promotes low temperature outgassing which is used in freeze drying, adhesive preparation, distillation, metallurgy, and process purging. The electrical properties of vacuum make electron microscopes and vacuum tubes possible, including cathode ray tubes. The elimination of air friction is useful for flywheel energy storage and ultracentrifuges.
Try to answer this question if possible: How does freeze drying, distillation and metallurgy benefit from a deep vacuum?
Answer:
Deep vacuum lowers the boiling point of liquids and promotes low temperature outgassing
