The 40,000-horsepower "electric/diesel hybrid locomotive" of the "SA3 Military Express Train" uses a double-headed iron horse originally made for pulling the Dora cannon: a technological upgrade of the Krupp D311 diesel locomotive.
The supporting locomotive prepared by Krupp for the heavy railway gun was designed and completed in 1940. This is a dual-engine fixed heavy-duty diesel-electric locomotive. It is also one of the German wartime locomotives. The Imperial Railway locomotive is code-named D311. The total length of the D311 locomotive is 22.51 meters, the total weight is 75+75 tons, and the axle type is Do+Do (D means four power axles, o means each axle is independent without linkage mechanism). The two machines are called car A and car B respectively. They both have driver's cabs. They have the same shape and are connected tail to tail. There are couplers and cables in the middle. There is no organ channel (organ-type door-type folding mechanism, similar to the hinged two-wheeler). section bus) and cannot be used separately (the split use of a dual-machine fixed heavy-duty locomotive will result in insufficient braking capacity). Due to circuit design limitations, two cars A or two cars B cannot be used in series. Whether in terms of structure or appearance, D311 is very close to modern fixed heavy-duty diesel locomotives.
Therefore, based on the technology of Krupp D311 dual-machine fixed heavy-duty diesel-electric locomotive, the GGL Greater Deutsche Locomotive Manufacturers Association wide-gauge test site completed the development of the "SA3 military diesel-electric hybrid locomotive".
Referring to the design blueprint of the "SA3 Military Express Train", female inventor Hedy Lamarr suggested installing the Z-4 computer in the "news carriage" of female reporters. Rather than being installed directly on the "Dora Cannon", a broad-gauge train gun with a total length of 53 meters, a height of 12 meters, and a total weight of 1,488 tons. In fact, this blueprint is definitely not the most accurate one. Faced with many uncertain plot elements, it is impossible for Mrs. Katie to show the accurate blueprint to others.
"It is said that the mathematical problems solved by this Z4 'prototype' are related to the development of jet fighters. It includes calculations of rocket trajectories, aircraft wings, vibration and dive. So if you want to adapt the Dora cannon, you must also develop a' New algorithm'." Female inventor Hedy Lamarr has no need to hide.
"This shouldn't be a problem for you, Heidi." The blueprints covering the desk in front of her were obviously not Mrs. Katie's strong suit.
"No, Katie. To be honest, mathematics is not a subject that I am proficient in. However, I can recommend someone." Thanks to the nominal "first husband" the famous Austrian arms tycoon Fritz Mandel's interest in science and invention Thanks to the funding, the female inventor Hedy Lamarr has a unique network advantage that her sisters do not have at all.
"Who is it?" Mrs. Katie was also curious.
"Lise Meitner." Female inventor Hedy Lamarr said a name that made everyone present feel very strange.
Lise Meitner, atomic physicist, radiochemist. She was the first scientist to theoretically explain Otto Hahn's discovery of nuclear fission. Her real name was Alice Meitner, who was born on November 7, 1878, in a Jewish family in Vienna, the capital of Austria. Her father was a lawyer. She was born and grew up in an era when women were barely allowed to receive education, and middle schools did not admit female students, so she had to attend a citizen school and obtained a French teacher qualification certificate after graduation. In 1901, Lize passed the examination through self-study and obtained a diploma from the Vienna Academy of Sciences High School. From this year on, she entered the University of Vienna to study physics, mathematics and philosophy. Under the guidance of her mentor Ludwig Boltzmann and others, she began to study radioactivity. In 1906, she received a doctorate in physics from the University of Vienna with her doctoral thesis "Thermal Conductivity in Inhomogeneous Substances", becoming the second female doctor in the history of the school.
In 1907, in order to study radiochemistry and atomic physics in more depth, Lise left Austria and came to Berlin, the then capital of the Prussian Empire, to join the Berlin University Research Institute. Women of that era were prohibited from receiving higher education. Thanks to the savvy chemist Emil Fischer, Lize was able to work in a research institute. But every time she entered the institute, she could only enter through the back door, and was not allowed to enter the student laboratory. She could only conduct experiments in a laboratory converted from a carpenter's workshop. Until 1909, when Prussia began to allow women to enter colleges and universities and research institutions, Lise did not have to enter the institute through the back door. Also in 1909, Lise discovered a series of radioactive isotopes with her colleague Otto Hahn. But at this time, her identity was "Hahn's assistant" and she was not allowed to complete the experiment independently. It was not until the outbreak of World War I that Hahn went to the front line to fight, and Liz finally got the opportunity to do experiments independently.
From 1912 to 1915, Lise worked with the famous physicist Planck, and finally became a full member of the institute in 1913 (all her previous work was unpaid). During World War I, she also served on the battlefield and worked as a nurse in a field hospital. In 1917, she returned to the laboratory and collaborated with Hahn on the discovery of protactinium-231, an isotope of protactinium. Unfortunately, when Hahn won the Nobel Prize in Chemistry for his research on radioactivity in 1944, Liesl Meitner's name was ignored, even though her efforts and achievements in this area were no less than Hahn's. But her research results are attributed to Hahn.
In 1938, World War II began and Hitler massacred the Jews. Lise had to flee to the Netherlands for refuge, and came to Norway in August 1938. After fighting hard, Lise found a position at the Nobel Institute in Stockholm. However, her supervisor at the time, Manne Siegbahn, discriminated against her and isolated her from the scientific research infrastructure. At this time, Hahn, a former colleague, wrote to tell her that he had discovered the fact that the product obtained by using neutrons to act on uranium has the radioactivity of barium. Lize immediately worked with her collaborator Frisch to provide a theoretical explanation for this amazing experimental result, and published it in the January 1939 issue of Nature.
In this article, she proposed a new concept in physics - nuclear fission. Lize was the first person to propose the term "fission". In the theory proposed by Lize, the total mass of the nucleus after fission is smaller than the mass of the uranium nucleus before fission, and the mass difference is converted into energy. She used Einstein's mass-energy equation to calculate that each atomic nucleus releases 200 million electron volts of energy during the fission process. This research result laid the foundation for the study of atomic bombs and atomic energy. Because of this research result, Liz was called the "Mother of the Atomic Bomb."
Although called the "Mother of the Atomic Bomb" by Europeans, Lise never participated in the development of the atomic bomb. She declined invitations from the Manhattan Project many times and stayed in Sweden during World War II. After 1944, she was nominated for the Nobel Prize three times, but unfortunately she failed to win. Beginning in 1947, Lize led the research work of the physics group at the Royal Institute of Technology in Sweden, and successively served as a visiting professor at some universities in the United States. Also in 1947, Lise received the Vienna Science Honor Prize and was elected as the first female academician of the Austrian Academy of Sciences.
During World War II, Hahn claimed Lise's work as his own, claiming he was protecting her. However, after the fall of the Nazis, Hahn continued to occupy Lise's research results. Although Bohr, Strassmann and other physicists all affirmed Lise's research results, Hahn was still unwilling to return the research results belonging to Lise to her. Lize was very disappointed with this, and eventually the two people who had worked together for more than ten years completely severed contact with each other. Lize was never married and had no children. This seemed to be due to her infinite love for physics, and perhaps more due to the status of women in Europe and America at that time: Although a group of professional women emerged during the two world wars, most of them were single. female. In people's general concept, if a woman gets married, she must devote herself to family life, be a housewife, take care of her husband and raise her children. Even the wife of the president is not exempt from this custom. And Lize once said: "I love physics. It is hard for me to imagine what my life would be like without physics. This is a very intimate love, just like loving someone who has helped me a lot." Li Ze in her later years Ze Meitner lives with his nephew and his family in Cambridge, England, and has been actively fighting for the peaceful use of nuclear fission.
After 1966, Meitner, who had worked in the field of atomic physics for 60 years, really attracted the attention of the world. She served on the United Nations Atomic Energy Commission and received numerous medals of honor. In Sweden, she also helped build the first peacetime nuclear reactors. Einstein, who had been paying attention to Liesl Meitner, called her "Germany's Marie Curie".
Lise Meitner died on October 27, 1968. Her tombstone is engraved with "A physicist who never lost her humanity." In order to commemorate her, later generations named the radioactive element 109, which was created in 1982, "Meitnerium".
Of course, like all the people in the show. This Lise Meitner is not a real person in history, but the heroine in "Lise Meitner - Die Mutter der Atomombe" (Are you sure, my lord? ).
"Born in 1878, I am 65 years old now (1943)." Mrs. Katie considered many factors.
