Since the purpose is to verify scientific experiments, scientific operations must be carried out to obtain scientific results.
Lin Hai decided to conduct all the experiments he could on the way to the southwest. After all, some experiments were not picky about the location. Even if they were discovered by his brothers, as long as it did not delay the trip, it would just be a little change of pace during the boring journey.
After spending a long time recalling and organizing, Lin Hai managed to recall as much of the courses from that year as possible.
Basic science is a science that studies natural phenomena and forms of material movement and explores the laws of development of nature.
It encompasses seven fundamental disciplines: mathematics, physics, chemistry, biology, astronomy, earth science, and logic, as well as their branches and interdisciplinary subjects. Interdisciplinary sciences include physical chemistry, chemical physics, biophysics, biochemistry, geophysics, geochemistry, and geobiology. Research results form the theoretical foundation of science and technology as a whole, guiding technical sciences and production technologies.
Of course, there are some scientific things that Lin Hai himself cannot verify through experiments, but some of them are actually not that difficult.
The first step is math.
Lin Hai still broke out in a cold sweat when he thought about mathematics. Sequences, limits, calculus, spatial analytic geometry and linear algebra, series, and ordinary differential equations flashed before his eyes.
Rolle, Lagrange, Cauchy, L'Hôpital, Taylor, Leibniz, Archimedes, Newton, Euler... Lin Hai felt like he was being stared at by countless eyes, each filled with a complex mixture of contempt and even a hint of confusion. Just like what Lin Hai's university math teacher had said to him earnestly: "It's so simple, why don't you understand?"
So, Lin Hai decided to only verify simple mathematical logic.
First, Lin Hai silently memorized all the numbers from 0 to 100 in his mind. Okay, the numbers existed. Then, he suddenly turned around and grabbed someone and asked directly, "Third brother, what do you think one plus one equals?"
Um?
Yin San didn't expect that Lin Hai would suddenly ask him this question. The question was so simple that Yin San, who was good at singing and dancing and never thought too deeply about things, felt that Lin Hai must have other deeper meanings, so he began to ponder.
Seeing Yin San actually thinking, Lin Hai felt a sense of immense terror. However, upon closer reflection, he realized that this was not the case. He was simply being obsessed. He had been handling the team's property for so long that he knew full well that basic mathematical logic for addition, subtraction, multiplication, and division existed in this world as well, and was consistent with the previous one.
Thinking of this, Lin Hai gave Wang Liang a look and took a few quick steps forward.
"Xiao Linzi, what's wrong? The third brother seemed a little strange after what you said."
"It's a bit strange. Third Brother must have traveled too much. I think he might be in a state of terror. I asked him what one plus one equals, but he hasn't replied yet."
As the eldest brother, Wang Liang felt extremely guilty for not noticing his brother's abnormal condition. He immediately used his traditional medical skills, rushed over, and shot two flashes of light at Yin San. He then shouted three times in his ear:
"wake up!"
"Wake up quickly!"
"If you don't wake up now, when will you wake up?"
After being hit in the ear by two ears, Yin San's mind was filled with various "wake up" sounds, which made him even more confused. He even looked up at the sky. Could it be that he really didn't wake up and was still dreaming?
Seeing Yin San's symptoms worsen, Wang Liang decided to take drastic measures. He grabbed the hatchet he had used to clear the way and chopped Yin San down on the head. Fortunately, the other onlookers kicked both men back, effectively separating them. Of course, Wang Liang later insisted that he only wanted to scare Yin San. The old man said that if someone is possessed, a little shock is enough to ease the situation.
Putting aside Wang Liang who was being chased and beaten by Yin San in front of the team, Lin Hai continued to think about what else he could do.
In this world, gravity exists, and it feels normal. There's wind and rain, and air flows normally. Fish in the water are streamlined. After shooting birds, I discovered their hollow bones and dense, long flight feathers, demonstrating the existence of the fundamentals of fluid mechanics and aerodynamics. You can run and jump by pushing off the ground, and you land. Pushing a cart hard will cause it to accelerate forward... In other words, fundamental physics exists, and so do the three laws of physics.
As for chemistry, it was even simpler, as Lin Hai had suggested to the captain not to drink raw water a few years ago (but he never cooked, and in fact he had never seen anyone boiling water or cooking. However, considering the captain's prestige, the execution of this military order should not be compromised), and he had made various filters with bamboo tubes and earthenware jars, and found a way to distill a little strong liquor (mainly because low-alcohol liquor was really hard to get) to help disinfect the wounded. It was easy for Lin Hai to think that he had inadvertently done basic chemical experiments in his life, from filtration, evaporation, fractionation, to extraction.
As for biology, Lin Hai looked at the roasted chicken in his hand. Well, the currently known animals and plants are the same as in the previous world, but pheasants are indeed more delicious than domestic ones. However, a large group of people rushed into the forest to hunt, and it is estimated that this forest will not recover for several years.
Astronomy, well, there's the sun in the sky... and the moon at night... Lin Hai didn't remember any star maps, but he had seen captains use the North Star to guide their direction. So, based on Lin Hai's astronomical knowledge, with the sun, moon, and North Star, he could pretty much conclude that astronomy was a good thing.
As for logic, Lin Hai felt that his own thinking proved the existence of logic.
The only thing that is difficult to prove is earth science, but after walking thousands of miles along the way, Lin Hai feels that he should be able to see something.
Well, since the basic science is roughly the same, Lin Hai feels that even if science is dead, it should still be able to be rescued.
The second blow came that night.
Lin Hai had never been a fireman before. Even now, on the way to migration, he didn't care about things like cooking. So the scene in the camp today deeply shocked him.
The water won’t boil!
