"Riemannian geometry and Einstein's field equations?"
Chen Yu's eyes widened in disbelief, and he sat up from the bed like a carp.
"That's what she told me anyway." Shanglu was sitting on the edge of his bed, lowering his head to twist the towel. Hot water dripped into the basin. He stared at the basin under him for a long time. Then he sighed faintly: "Hey, do you think this is my inescapable fate? Why didn't anyone tell me before I came here? I have to study general relativity after graduation..."
"Young engineer, you are a top student." Chen Yu comforted him, "You can handle it."
"Did you study macro photography when you were in college?" Shang Lu tilted his head and spoke fiercely.
"No...no." Chen Yu said, "If we don't learn this, it will sound scary."
"It's even more scary to learn. Not many people can master this stuff, and Teacher Ji doesn't understand either. He is engaged in engineering, not theoretical physics. Damn... he doesn't even know how to learn it, so why should I learn it?" Huh? When I was studying the basics of macroscopic theory, one tensor analysis tortured me to death." Phytolacca put a towel on the bedside, took off his smelly socks and stuffed them into his shoes, and then walked back. He fell down, leaning on the soft pillow, staring straight at the ceiling, "Hey, you must not know what the pilots of those giant machines are doing. This is so fucked."
"How fucked up?"
"Very, very fucked up."
"Then, little chief engineer, you are a good person and a blessing to the heavens."
Chen Yu's eyes turned pitiful.
"On the battlefield against angels, just being a pilot is useless." Phytophaga said quietly, "You must be a mathematician and a physicist."
Shanglu's impression of giant weapons has been completely overturned and reversed today. He realized that compared to combat weapons, giant weapons are more similar to a powerful and sophisticated gravity detector and a supercomputer. Compared to aircraft, tanks, cannons, and warships, Giant machines are closer in blood relationship to the Large Hadron Collider or high-energy particle accelerators. Shen Jiang is right. Honglian is a giant physicist. She needs to think about difficult and complex physical problems on the battlefield and make immediate analysis and calculations. This is the basis for effectively fighting four-dimensional monsters like angels, but this how can that be possible?
How could there be such a war in human history?
Soldiers holding guns need to analyze the Dirac equation, perform Lorentz transformation or other messy physical laws on a battlefield under heavy gunfire to find the target. This sounds like forming an army composed of Bohr, Dirac, Where can the army composed of Riemann, Hilbert, Minkovsky, Feynman and Einstein find such soldiers?
But his grandma's was actually found by them.
This is probably the most demanding and difficult selection standard in human history. It requires drivers to be proficient in numerical relativity while learning to operate giant machines and fight angels.
"Fuck-"
Shanglu covered his face and sighed.
No one understands what this means better than Phytolacca - Einstein's field equations are the core of the general theory of relativity, a formula that describes changes in space and gravity, and can be said to be the most complex system of equations in human history. The founder, Einstein, Einstein himself was unable to solve it. It was so complicated that it was almost impossible to find a general or precise solution, but the pilot of the giant machine needed to analyze and solve it when facing the angel! Using the powerful computing power of supercomputers to violently solve Einstein's field equations and obtain approximate solutions - this is the core task of giant machine pilots in combat.
It is equivalent to solving extremely complex second-order nonlinear partial differential equations on a flight that is about to crash. The time is urgent and life and death are speedy. If it succeeds, everything will be fine, but if it fails, mankind will be doomed.
This requires that the driver must be an extremely gifted genius in mathematics and physics, with in-depth research and sensitivity far beyond ordinary people in the field of general relativity, and even mental calculation of partial differential equations. Shen Jiang said that there may be one such genius in 100,000 people.
"What a fucking pervert."
Phytolacca murmured.
Shen Jiang is such a pervert.
I really can't tell - that young girl in her twenties or seventies is actually the top numerical relativity expert in the human world.
Old Man Ji lived a long life and passed away to Staff Officer Huang (Officer Huang was the Chinese pastoral dog raised by Old Man Ji).

"What is this? Where is the summation symbol? Oh yes, this is the Einstein summation symbol... tensor reduction? How to reduce it?"
Shang Lu was mumbling, turning over a large stack of photocopied handouts in his hand. Chen Yu took the basin and went out to fill the water. He was the only one left in the dormitory. Everyone in the 151 base had their own jobs and combat positions. , but no one is as special as Phytolacca. He feels that the difficulty of his job is definitely not at the same level as others. At least the staff of the headquarters, the officers of the political department, the equipment department, the assistants of the logistics department, and all workers do not need to learn how to do it after get off work. Maintain giant machines, not to mention Riemannian geometry and general relativity.
Except for the pilot of the giant machine.
Old Man Ji really thinks highly of himself.
"Go to hell with tensor analysis!" Phytolacca fiercely smashed a large stack of A4 paper on the bed, "I won't learn anymore! This is not what I came to 151 for! I won't fucking learn anymore!"
"Little chief engineer, nothing is difficult in the world, as long as you persist." Chen Yu came in with a washbasin and slippers, and closed the door behind him, "Even if it's mathematics -"
"Then you learn." Shanglu pointed out his hand.
"It's not that I don't want to learn, it's just that a famous and successful senior once taught me..." Chen Yu said, "Study is nothing."
"Teacher Ji, please hire someone else. I really don't understand this thing. What kind of engineering and theory do you need to grasp with both hands and be strong with both hands? He can't understand this thing himself." Shanglu said, "Starting tomorrow I started working with the sales manager, and I would rather help him design a coal-fired aviation engine..."
Before he finished speaking, there was a muffled sound outside the window: "Bang!"
There was silence in the yard, and a few seconds later someone from the next building shouted:
"Business chief——!"
"It's nothing! It's nothing!" shouted the sales manager, "A little too much pulverized coal was added! A small problem -!"
Phytolacca let out a long sigh and lay down on the bed.
"The great Albert Einstein gave us a powerful weapon, but it is so difficult to operate that few people in the world can master it."
If placed in a fantasy worldview, it is the ultimate magic left by the ancient supreme wizards to fight against demons. It is the only way to detect the disguise of demons. However, this set of magic rules is so difficult that even the utmost human wisdom is difficult to master.
Shanglu thought about Shen Jiang again. She was the genius warrior who had mastered this ultimate set of magic, so she had to drive giant weapons to fight against the angels.
Sounds really heroic.
But not many people know that what these heroes have to face in the cockpit of giant weapons is complex gravity analysis and equation solving. The common story of sad and angry memories of loved ones yelling and a small universe exploding to fight back doesn't work here. Because what you are facing is mathematics, and if you are not good at mathematics, you are not good at it.
"Where is the lighthouse angel?" Phytolacca turned around and asked.
"We are still approaching slowly. We estimate that we will pass through the second-level contact buffer zone in the next three days to a week. The specific situation will not be known until the shift meeting tomorrow morning." Chen Yu leaned on the bed and stretched out his hand towards Phytolacca , "Come let me see that thing."
Phytolacca handed him the handout.
He glanced and said, "Fuck, I'm blind."

The next day.
Old Man Ji directed the crane to lift a large piece of hollowed-out and carved aluminum alloy frame. This is the frame of the shield. The frame needs to be light and strong, and aluminum alloy can meet the requirements. As for the material of the shield surface, hafnium carbide ceramics, it has been Sent for high temperature ablation test.
151 built a rocket test bed on the campus of Chongqing University of Posts and Telecommunications, and put a solid fuel rocket on the test bed. Of course, the purpose was not to test the rocket engine. What they wanted to test was the long-term ablation resistance of high-temperature resistant ceramics. The temperature of the tail flame ejected by the rocket engine can reach 4,000 degrees Celsius, which is a suitable testing method, and the tantalum-hafnium pentacarbonate ceramic tile is lying under the nozzle of the rocket engine.
These people are so cruel, they will be burned under the rocket.
Two hundred meters away, Phytolacca stood in a semi-underground bunker wearing goggles, looking at the test platform in the center of the playground from a distance.
"Get ready for the test! This is Zero, everyone pay attention, countdown to ignition in five seconds -"
