Problem: Background: Salvador Domingo Felipe Jacinto Dali i Domenech, Marquis of Dali de Pubol (11 May 1904 - 23 January 1989), known professionally as Salvador Dali ( Catalan: [s@lb@'do d@'li]; Spanish: [salba'dor da'li]), was a prominent Spanish surrealist born in Figueres, Catalonia, Spain. Dali was a skilled draftsman, best known for the striking and bizarre images in his surrealist work. His painterly skills are often attributed to the influence of Renaissance masters.
Context: Dali employed extensive symbolism in his work. For instance, the hallmark "melting watches" that first appear in The Persistence of Memory suggest Einstein's theory that time is relative and not fixed. The idea for clocks functioning symbolically in this way came to Dali when he was staring at a runny piece of Camembert cheese on a hot August day. The elephant is also a recurring image in Dali's works. It appeared in his 1944 work Dream Caused by the Flight of a Bee Around a Pomegranate a Second Before Awakening. The elephants, inspired by Gian Lorenzo Bernini's sculpture base in Rome of an elephant carrying an ancient obelisk, are portrayed "with long, multijointed, almost invisible legs of desire" along with obelisks on their backs. Coupled with the image of their brittle legs, these encumbrances, noted for their phallic overtones, create a sense of phantom reality. "The elephant is a distortion in space", one analysis explains, "its spindly legs contrasting the idea of weightlessness with structure." "I am painting pictures which make me die for joy, I am creating with an absolute naturalness, without the slightest aesthetic concern, I am making things that inspire me with a profound emotion and I am trying to paint them honestly." --Salvador Dali, in Dawn Ades, Dali and Surrealism. The egg is another common Daliesque image. He connects the egg to the prenatal and intrauterine, thus using it to symbolize hope and love; it appears in The Great Masturbator and The Metamorphosis of Narcissus. The Metamorphosis of Narcissus also symbolized death and petrification. There are also giant sculptures of eggs in various locations at Dali's house in Port Lligat as well as at the Dali Theatre and Museum in Figueres. Various other animals appear throughout his work as well: ants point to death, decay, and immense sexual desire; the snail is connected to the human head (he saw a snail on a bicycle outside Freud's house when he first met Sigmund Freud); and locusts are a symbol of waste and fear. Both Dali and his father enjoyed eating sea urchins, freshly caught in the sea near Cadaques. The radial symmetry of the sea urchin fascinated Dali, and he adapted its form to many art works. Other foods also appear throughout his work.
Question: Were there other artworks with melting watches?
Answer: The idea for clocks functioning symbolically in this way came to Dali when he was staring at a runny piece of Camembert cheese on a hot August day.

Problem: Background: Legion (David Charles Haller) is a fictional superhero appearing in American comic books published by Marvel Comics. He is the mutant son of Professor Charles Xavier and Gabrielle Haller. Legion takes the role of an antihero who has a severe mental illness including a form of dissociative identity disorder, in which each of his alternate personas controls one of his many superpowers. The television series Legion premiered on FX network in 2017.
Context: When Mystique tracked down David years later to get revenge for "his" murder of Destiny, he awakened with his fractured mind healed. David had a new goal, to help his father realize his dream of human-mutant coexistence by killing Magneto, Xavier's greatest opponent, before he had a chance to amass power. He traveled twenty years into the past, when Xavier and Magneto were orderlies at the mental hospital. In the process, he loses his memory. Magneto then accidentally triggers his memory, causing David to go on a rampage, attacking Magneto and revealing the existence of mutants to the public decades too early. Several X-Men who were pulled back in time with him were unable to prevent him from attacking Magneto. Xavier, however, leaped into the path of the psi-knife (the focused totality of Legion's psionic powers) and was killed in Magneto's place, causing the formation of the Age of Apocalypse timeline. Due to being trapped in the past by David's actions, Bishop enlisted the aid of the new reality's X-Men to travel back in time to confront Legion again. Bishop seized Legion's psi-blade and drove it into his own chest, allowing Legion to see the future that he caused. In his last moments, David apologized for what he did. David's mother, Gabrielle Haller, described having a "maternal loss" afterward, implying she miscarried before giving birth to David. While David was considered deceased, some of his alternate personalities remained trapped between life and death, manifesting as spirits. When the spirits started terrorizing Israel, Excalibur was called to stop them. After learning that the spirits were refusing death, Meggan used her empathy to calm their rage, convincing them to go "towards the light."
Question: How did they travel back in time?

Problem: Background: Tu Youyou (Chinese: Tu You You ; pinyin: Tu Youyou; born 30 December 1930) is a Chinese pharmaceutical chemist and educator. She is best known for discovering artemisinin (also known as qinghaosu) and dihydroartemisinin, used to treat malaria, which has saved millions of lives.
Context: Tu Youyou was born in Ningbo, Zhejiang, China on 30 December 1930. She attended Xiaoshi Middle School for junior high school and the first year of high school, before transferring to Ningbo Middle School in 1948. From 1951 to 1955, she attended Peking University Medical School / Beijing Medical College. Tu studied at the Department of Pharmaceutical Sciences, and graduated in 1955. Later Tu was trained for two and a half years in traditional Chinese medicine. After graduation, Tu worked at the Academy of Traditional Chinese Medicine (now the China Academy of Traditional Chinese Medical Sciences) in Beijing. She was promoted to a Researcher (Yan Jiu Yuan , the highest researcher rank in mainland China equivalent to the academic rank of a full professor) in 1980 shortly after the Chinese economic reform began in 1978. In 2001 she was promoted to academic advisor for doctoral candidates. Currently she is the Chief Scientist in the Academy. As of 2007, her office is in an old apartment building in Dongcheng District, Beijing. Before 2011, Tu Youyou had been obscure for decades, and is described as "almost completely forgotten by people". Tu is regarded as the Professor of Three Noes - no postgraduate degree (there was no postgraduate education then in China), no study or research experience abroad, and not a member of any Chinese national academies, i.e. Chinese Academy of Sciences and Chinese Academy of Engineering. Up until 1979, there were no postgraduate degree programs in China, and China was largely isolated from the rest of the world. Tu is now regarded as a representative figure of the first generation of Chinese medical workers since the establishment of the People's Republic of China in 1949.
