The 40,000-horsepower "electric/diesel hybrid vehicle front" uses a technology upgraded and transformed by the Krupp D311 internal combustion locomotive, which was originally built to traction Dora cannons.

The supporting locomotive prepared by Krupp for heavy railway guns was completed in 1940. This is a dual-machine fixed reconnected diesel-electric locomotive, and is also a model of 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 shaft type is Do

Do (D represents four power axles, and o represents independent and no linkage mechanism for each axle). The two machines are called A and B respectively. They both have driver rooms, with exactly the same shape, with tail-to-tail connection, with a hook and cable in the middle. There is no organ passage (organ-type door-type folding mechanism, similar to articulated two-section bus), and cannot be separated and used separately (split and used by the dual-machine fixed reconnection locomotives will lead to insufficient braking capacity). Due to the limitations of the circuit design, two A and two B cars cannot be used in series. Whether in terms of structure or appearance, the D311 is already very close to modern fixed reconnection diesel locomotives.

Therefore, based on the technology of Krupp D311 dual-machine fixed reconnected diesel-electric locomotive, the GGL Big German Locomotive Manufacturers Federation completed the development of the "SA3 military diesel-electric hybrid vehicle head".

Referring to the design blueprint of the "SA3 Military Rapid Train", female inventor Heidi Rama suggested installing the Z-4 ​​computer in the "news car" of the female reporter. Instead of directly installing it on the "Dora Cannon" with a total length of 53 meters, a height of 12 meters, and a total weight of 1,488 tons. In fact, this blueprint must not be the most accurate one. Faced with many plot elements that are not yet certain, Mrs. Katie could not show the accurate blueprint generously.

"It is said that the mathematical problems solved by this Z4 'prototype' are related to the development of jet fighters, including rocket trajectory, aircraft wings, vibration and dive calculations. So if you want to adapt to the Dora cannon, you must also develop a 'new algorithm'." The female inventor Heidi Rama no longer needs to hide it.

"This shouldn't be a problem for you, Heidi." The blueprint covered with desks in front of him was obviously not Mrs. Katie's strength.

"No, Katie. To be honest, mathematics is not a subject I am proficient in. However, I can recommend one person." Thanks to the nominal "first husband" of the famous Austrian arms tycoon Fritz Mandel, the female inventor Heidi Rama has a unique connection advantage that several sisters do not have.

"Who is it?" Mrs. Katie was also very curious.

"Lizer Metner." The female inventor Heidi Rama said a name that made everyone present feel very strange.

Lise

Meitner, an atomic physicist and radiochemist. She was the first scientist to theoretically explain the nuclear fission discovered by Otto Hahn. Her real name was Alice Meitner. She was born on November 7, 1878 in a Jewish family in the Austrian capital Vienna. Her father was a lawyer. When she was born and raised, women were almost allowed to receive education, and middle schools did not enroll female students, so she had to attend a citizen school and obtained after graduation.

He received a French teacher qualification certificate. In 1901, Lizer passed the self-study exam and obtained a diploma from the Vienna Academy of Sciences. 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 obtained a Ph.D. in physics from the University of Vienna with her doctoral thesis "Thermal Conductivity in Uneven Matter", becoming the second female doctor in the history of the school.

In 1907, in order to learn radiochemistry and atomic physics more deeply, Lizer left Austria and came to Berlin, the capital of the Prussian Empire, and joined the Institute of the University of Berlin. Women in that era were forbidden from higher education. Fortunately, chemist Emil Fischer was able to enter the institute for work. However, every time she entered the institute, she could only enter the back door and was not allowed to enter the student laboratory. She could only do experiments in a laboratory transformed from a carpenter's workshop. It was not until 1909 that Prussia began to allow women to enter universities and research institutions, and Lizer did not have to enter the institute through the back door. It was also in 1909 that Lizer and her colleague Otto Hahn (Otto).

Hahn discovered a series of radioactive isotopes together. 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 participate in the war, and Lizer finally got the opportunity to conduct experiments independently.

From 1912 to 1915, Lizer worked with the famous physicist Planck, and finally became a full member of the institute in 1913 (all her work was free before). During World War I, she also went to the battlefield and worked as a nurse in a field hospital. In 1917, she returned to the laboratory and cooperated with Hahn to discover the isotope of Hahn. Unfortunately, in 1944, when Hahn won the Nobel Prize in Chemistry for radioactive research, Lizer Metner's name was ignored. Although she made no less results than Hahn in this regard, her research results were all attributed to Hahn.

In 1938, when World War II began, Hitler massacred Jews, Lizer had to flee to the Netherlands for refuge and came to Norway in August 1938. After striving for it, Lizer obtained a position at the Nobel Institute in Stockholm. However, her superior Manne Siegbahn discriminated against her and isolated her from the infrastructure of scientific research. At this time, former colleague Hahn wrote to her that she discovered the fact that the product obtained by using neutrons to act on uranium had the radioactivity of barium. Lizer immediately and his collaborator Frisch gave a theoretical explanation of the astonishing experimental results and published it in the journal Nature published in January 1939.

In this article, she proposed a new concept in physics - nuclear fission. Lizer was the first to propose the word "fission". In the theory proposed by Lizer, the total mass of the nucleus after fission is smaller than the mass of the uranium nucleus before fission, and the difference in mass is converted into energy. She used Einstein's mass-energy equation to calculate the energy of 200 million electron volts released by each nucleus during fission. This research result laid the foundation for the research of atomic bombs and atomic energy. Also because of this research result, Lizer is called the "mother of the atomic bombs."

Although she was called the "Mother of the Atomic Bomb" by Europeans, Lizer has never participated in the development of the atomic bomb. She repeatedly refused the invitation from the Manhattan Project in the United States. During World War II, she stayed in Sweden. After 1944, she was nominated for the Nobel Prize three times, but unfortunately she failed to win the award. Since 1947, Lizer led the research work of the Physics Group at the Royal Swedish Institute of Technology, and successively served as a visiting professor at some universities in the United States. In 1947, Lizer won the Vienna Science Honor Award and was elected as the first female academician of the Austrian Academy of Sciences.

During World War II, Hahn attributed Lizer's achievements to her name and claimed to be a protection for her. However, after the fall of the Nazis, Hahn continued to occupy Lizer's research results. Although physicists such as Bohr and Strasman affirmed Lizer's research results, Hahn was still unwilling to return the research results belonging to Lizer to her. Lizer was very disappointed with this, and in the end, the two who had worked together for more than ten years completely cut off contact. Lizer was unmarried and had no children for life, which seemed to be due to her infinite love for physics, and perhaps more because of the status of women in Europe and the United States at that time: although the world was twice.

During the war, a group of working women emerged, but most of them were single women. In the general concept of people, if women get married, they must devote themselves to family life, be housewives, take care of their husbands and children, and even the president's wife is not immune to the vulgarity. Lizer once said: "I love physics, and it is hard for me to imagine what would happen if there is no physics in my life. This is a very intimate love, just like loving someone who helped me a lot." In his later years, Lizer Metner lived in Cambridge, England with his nephew's family, and has been actively striving for the peaceful use of nuclear fission.

After 1966, Maitner, who had worked in the field of atomic physics for 60 years, has truly 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 has been following Lizer Maitner, called her "Marie Curie of Germany".

On October 27, 1968, Lizer Metner died. Her tombstone was engraved with "A physics who never lost her humanity". In memory of her, later generations named the radioactive element No. 109, which was created in 1982, "Meitnerium".

Of course, it is like all the people in the play. This Lise Meitner is not a real person in history, but the heroine in "Lise Meitner - Die Mutter der Atombombe" (Are you sure, sir?).
