"You are right. So after the 'Salon Girl', we will have our own 'Lightning Girl' again." Mrs. Katy, the casting assistant director, saw the "official mattress" and the other side of "soldier's whip": "It is also based on the minimum age of 17 years old and the maximum age of 30 years old?"

"Aged 18 to 30." Female director Leni Rivenstale almost subconsciously raised the minimum age.

"Ah..." Mrs. Katy, the casting assistant director, understood immediately. This was the beginning of their common "close-up memory".

As the "Rose of Empire" and "Mother of Documentary", Leni Rivenstale, a dancer, movie star, famous director and photography master, was born on August 22, 1902. Today is her 41st birthday. As a middle-aged woman, her memories of youth must be unforgettable. This emotional memory that started at the age of 18 must be extremely rich. This means that the plot nodes of one-click replacement must be enough to satisfy another well-deserved "hard connection" and "soft connection" that are positively related to the nature of life of "satisfied with the flesh and pleasant spirit", to satisfy another well-deserved "invincible existence and the peak of human nature". As long as you finish the "cache progress bar", the spiritual core can solidify into a main sequence precedent star beyond the quasar at the edge galaxy.

"Everyone, we succeeded." As he was speaking, the female inventor Heidi Rama, wearing an engineer's uniform, stepped into the director's carriage excitedly.

"Z-4 computer?" The female reporter walked out of the film cutting room immediately thought of it.

"Yes, not right." Female inventor Heidi Rama has been busy developing the latest Z-4 computer with the "father of computers" Conrad Chuze for Dora Cannon these days.

"What do you mean?" The female reporter immediately became interested.

"The Z-3 computer used 2,600 relays, inputted with perforated paper tape, and realized binary number program control. As early as 1938, Chu Ze and his friends were already considering assembling new computers with 2,000 electronic tubes and other electronic components. But for well-known reasons, where did the self-made civil engineers get electronic tubes that are much more advanced than relays. You should know that this is military supplies.

Therefore, the more advanced electromagnetic Z-4 computer, although the memory unit is expanded from 64-bit to 1024-bit, the relays used almost fill a room. Even in order to improve computing efficiency, Chuze designed a programming language "Plankalkul, meaning "proper system of planning"" but relays are still the most important disadvantages that affect performance." Female inventor Heidi Rama changed the tone: "However, after joining us, all the disadvantages are solved. Therefore, the latest version of Z-4 has been upgraded from an electromagnetic computer to an electronic tube computer. Compared to Z-3, which can complete 3 to 4 addition operations per second, or complete a multiplication operation within 3 to 5 seconds, Z-4 can perform 5,000 addition operations per second."

"My God, this is definitely a huge improvement." The female reporter was shocked. You should know that this was 1943.

"This is actually the ascension brought by new materials." The female inventor Heidi Rama suddenly had an idea: "I seem to have some impression of the research on new materials with similar functions...ah, it is Robert and Rudolph of the University of Göttingen."

In 1938, Robert Pohl and Rudolf Hilsch conducted experiments on potassium bromide crystals with three electrodes at the University of Göttingen. They reported amplification results for low-frequency (about 1 Hz) signals.

Earlier in 1934, while working at the University of Cambridge, German electrical engineer and inventor Oskar Heil applied for a patent that controls currents in semiconductors—essentially field effect transistors—through capacitive coupling on electrodes.

That's right, transistors. As long as you can research more advanced transistors before Americans, Conrad Chuze, the "father of computers", can upgrade the Z-4 ​​tube computer to a more powerful Z-5 transistor computer.

This plot, Danielle, a battlefield girl who did her homework when she came, watched the whole process. It was not until the female inventor Heidi Rama said in person that "Robert and Rudolph of the University of Göttingen" that she showed a "spoiler-derived" smile.

The reason is very simple. This is another "key side node" that changes the plot.

The invention of transistors can be traced back to 1929. Although engineers had obtained a patent for a transistor, due to the technical level at that time, the materials used to make transistors did not reach sufficient purity, which made them unable to be truly made. Until December 1947, a research team composed of Shockley, Barding and Bratton of Bell Laboratory in the United States developed a point-contact germanium transistor. In 1956, William Shockley, John Bardeen and Walter Brattain won the Nobel Prize in Physics for inventing transistors. William Shockley was also known as the "father of transistors."

Of course, there is also a possibility that the fall of the Third Reich forced German engineers to interrupt their research on transistors. Just as when Conrad Chuze, the "father of computers", heard after the war that the University of Pennsylvania in the United States had already developed an electronic tube computer, he couldn't help but sigh: "All I can do is just shake my head."

There is no need to worry about changing the historical trajectory of the plot time and space. Because when this computer specially designed for "Jie Shi" left this "World War II plot fragments similar to the similar and fusion of cross-plot space" in this "Battle" will also end.

"In order to write a scientific ballistic calculation program for Dora Cannon, we also need to rescue Lizer Metner, the 'Mother of the Atomic Bomb'. This may be a key step to correct the plot of World War II." Heidi Rama, the female inventor who started a new personal plot, was shining: "All nuclear physicists are senior mathematicians. Although they are not as good as Emmy Noether in the field of mathematics, Lizer Metner has more than enough mathematical attainments to write ballistic calculation programs for Dora Cannon."

"So, where is this 'Mother of the Atomic Bomb' now?" The female reporter looked at the casting assistant director Mrs. Katy.

"The Gotov Test Station of the Army Ordnance." Mrs. Katie was well-informed in the Berlin upper circle: "The Gotov Test Station of the Army Ordnance has been providing uranium crystals for experimental uranium machines (uranium reactors)."

"I don't understand why the 'Revenge Weapons Project' requires Liz Metner, who has good mathematical attainments." The female inventor Heidi Rama said that the female inventor, Danielle, who did his homework when he came, listened to it with great intentions.

In fact, there is a widely spread saying about why the Third Nazi Empire was clearly leading step by step in nuclear experiments but failed to create an atomic bomb in the end: Werner Heisenberg, the main founder of quantum physics and a famous Nobel Prize winner, accidentally calculated the weight of the key factor uranium 235 when calculating the components of the atomic bomb.

The calculation result of the Heisenberg team at that time was that an atomic bomb needed at least several tons of uranium 235! According to the industrial technology around the world at that time, several tons of uranium 235 could not be produced at any rate. In other words, this atomic bomb could not be produced because of the difficulty of uranium 235. Therefore, in June 1942, Werner Heisenberg wrote a report to explain the situation to the top German Nazis. He concluded that the atomic bomb could not be completed in a short time. At that time, the situation in Nazi Germany was already in a state of great trouble, and there was no time or financial resources to support a long-term plan that could not be hoped. Therefore, he decided to give up the research of atomic bomb directly and instead study other weapons of destruction. Even so, the German government still allocated Werner Heisenberg 350,000 Empire Mark to allow him to continue researching nuclear objects.
