Defend Namsan Park

Chapter 11 The Ultimate Magic of the High Mage

"Riemannian Geometry and Einstein's Field Equations?"

Chen Yu opened his eyes wide, and a carp stood up straight from the bed.

"That's what she told me." Shang Lu was sitting on the edge of his bed, twisting a towel with his head bowed. Hot water dripped into the washbasin. He stared blankly at the basin under him. He sighed faintly: "Hey, do you think this is my inescapable fate? Why didn't anyone tell me before I came here? I still need to learn general relativity..."

"Little chief engineer, you are a top student." Chen Yu comforted him, "You can handle it."

"Did you study Guangxiang when you were in college?" Shanglu said fiercely.

"No...no." Chen Yu said, "We don't learn this."

"Not many people can be proficient in this stuff, and Mr. Ji doesn't understand either. He is engaged in engineering, not theoretical physics. Damn... he doesn't even know how to do it himself. Why should I learn it? When he chose Guangxiang When I was in the theoretical foundation, a single tensor analysis tortured me to death." Phytophthora put the towel on the head of the bed, took off the smelly socks and stuffed them into the shoes, then fell back, leaning against the soft On the pillow, staring straight at the ceiling, "Put it on, you must not know what the pilots of those giant machines are doing, it's so fucking crazy."

"How fucked up?"

"On the battlefield against angels, just being a pilot is useless." Physicum said, "You have to be a mathematician and a physicist."

Shanglu's impression of giant machines has been completely subverted and reversed today. He realized that compared to combat weapons, giant machines are more similar to a powerful and sophisticated gravity detector and supercomputer. Compared to aircraft, tanks, cannons, and warships, Juji is closer to the Large Hadron Collider or high-energy particle accelerator in terms of blood relationship.What Shen Jiang said is correct. Honglian is a giant physicist. She needs to think about difficult and complicated physical problems on the battlefield, and make analysis and calculations immediately. 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 with guns need to analyze the Dirac equation, perform Lorentz transformations, or other messy laws of physics on the battlefield full of gunfire to find the target. This sounds like a team consisting of Bohr, Dirac, An army of Riemann, Hilbert, Minkowski, Feynman, and Einstein, where to find such soldiers?
But his grandma's was actually found by them.

This is probably the most demanding and difficult selection standard in the history of human beings. It requires the pilot to be proficient in numerical relativity while learning to operate giant machinery and fight against angels.

"Fuck me-"

Shang Lu covered his face and sighed.

No one can understand what this means better than pokeweed - the Einstein field equation is the core of the general theory of relativity, and it is a formula describing the changes in space and gravity. It can be said to be the most complicated equation system in human history. The founder love Einstein himself is powerless to solve it, it is so complex that it is almost impossible to find a general solution and an exact solution, but the driver of the giant machine needs to analyze and solve it when facing the angel!Use the powerful computing power of supercomputers to violently solve Einstein's field equations and obtain approximate solutions - this is the core task of giant machinery drivers in combat.

It is equivalent to solving the extremely complex second-order nonlinear partial differential equations in the flight that is about to crash. The time is urgent and the speed of life and death is fast.

This requires that the driver must be an extremely gifted mathematics and physics genius, 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 among the [-] candidates with such potential, it is possible There is one.

"What a fucking pervert."

Shanglu murmured.

Shin Kang is such a pervert.

I really can't tell - that young 27-year-old girl is actually the top numerical relativity expert in the human world.

Old man Ji has lived a long time on Staff Huang (Huang Staff is 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 contraction? How?"

Shang Lu was muttering, turning over a large stack of photocopied handouts in his hand, Chen Yu went out with a washbasin to pour water, and he was the only one left in the dormitory, everyone in Base 151 had their own jobs and positions , but no one is as special as Phytophthora. He feels that the difficulty of his work is definitely not at the same level as that of others. At least the officers and assistants of the staff and political department of the headquarters, the assistants of the logistics department, and all workers do not need to learn how to get off work after work. Maintain giant machines, not to mention Riemannian geometry and general relativity.

Except for the driver of the giant machine.

Old man Ji really thinks highly of himself.

"Go to hell with tensor analysis!" Shang Lu viciously smashed a large stack of A4 papers on the bed, "I don't want to learn anymore! That's not what I came to 151 for! I don't fucking want to learn anymore!"

"Little chief engineer, nothing is difficult in this world, as long as you are willing to persevere." Chen Yu came in with a washbasin and slippers, and closed the door behind him, "Even if it is mathematics—"

"Then you learn." Shanglu pointed.

"It's not that I don't want to learn, it's just that there was once a famous and successful senior who taught me..." Chen Yu said, "Study, learn a fart."

"Let Mr. Ji hire someone else, I really don't understand this thing, what kind of engineering and theory, both hands must be grasped, both hands must be hard? He himself can't understand this thing." Shanglu said, "From tomorrow At first, I worked with the sales manager, and I would rather help him design a coal-fired aero engine..."

Before the words fell, there was a muffled "Boom!" outside the window.

There was silence in the courtyard, and a few seconds later someone from the next building shouted:
"Business chief—!"

"No trouble! No trouble!" The salesman shouted, "A little too much pulverized coal is added! A small problem—!"

Shanglu let out a long sigh and lay dead on the bed.

"The great Albert Einstein gave us a powerful weapon, but one so difficult to operate that few in the world can master it."

If it is placed in a fantasy world view, 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, but this set of magic rules is so difficult that it is difficult for poor human wisdom to master.

Shang Lu thinks about Shen Jiang again, she is the genius warrior who has mastered this set of ultimate magic, so she wants to drive a giant machine to fight against the angel.

Sounds really heroic.

But few people know that these heroes are facing complex gravitational analysis and equation solving in the cockpit of the giant machine. The routine of sad and angry memories of loved ones yelling at the small universe to fight back in common stories will not work here, because What you are facing is mathematics. If you don’t know mathematics, you won’t know it, and you won’t even shout out your throat.

"Where is the lighthouse angel?" Shanglu turned around and asked.

"It's still approaching slowly. We estimate that we will pass through the second-level contact buffer zone in the next three days to one week. The specific situation will not be known until the shift meeting tomorrow morning." Chen Yu leaned on the head of the bed and reached out to Shang Lu , "Come and show me that thing."

Shanglu handed him the handout.

He glanced at it, "Fuck, I'm blind."

The next day.

The old man Ji commanded the crane to hoist a large aluminum alloy frame with hollow carvings as a whole. This is the frame of the shield. The frame is required 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 adopted Sent for high temperature ablation testing.

151 built a rocket test bench on the campus of Chongqing University of Posts and Telecommunications. A solid-fuel rocket was mounted on the test bench. 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 tail flame temperature of the rocket engine can reach [-] degrees Celsius, which is a suitable test method, and the ceramic tile of tetratantalum hafnium pentacarbide is lying under the nozzle of the rocket engine.

These people are really ruthless, they are burned under the rocket.

200 meters away, Shanglu was standing in a semi-underground bunker wearing goggles, looking at the test platform in the middle of the playground from a distance.

"Prepare for the test! This is number zero, everyone pay attention, count down to five seconds to ignite—"
