Beneath Deep Space

"... Such inspiration comes from a button battery created by aliens. For its basic theory and related formulas, please refer to page 27 of the paper, where there will be a detailed discussion..." Very surprised, a button battery A small button battery can bring such great inspiration to mankind. I have to say that UFO civilization is really countless times more powerful than new human civilization.

Yu Yifeng listened with great interest at first, but then he became confused and dizzy, and he could only follow the others to page 27 in a daze.

"The mass-energy equation E=mc^2 of the great scientist Einstein is not only applicable to nuclear energy, but also to chemical energy! The loss of mass is actually everywhere!"

While holding an experimental aluminum-air battery, Felix said passionately: "In our daily lives, we have long learned to use the loss of mass to create energy...two hydrogen atoms and one oxygen atom combine , when forming a water molecule, the mass of the water molecule must be less than the sum of the masses of two hydrogen atoms plus one oxygen atom."

"This reduced mass becomes energy, although the change in mass is very small... Our idea is to expand the mass loss as much as possible and increase the release of chemical energy..."

Well, it’s really a long-lasting series. Yu Yifeng looked troubled. It seemed like it was the first time he heard this statement. What surprised him was that most scientists nodded in agreement...

Changes in chemical energy can also cause changes in mass!

Yu Yifeng could swear that this was the first time he heard this statement. But seeing that the large number of material scientists around him had no objections, he didn't dare to say anything to avoid embarrassing himself.

As for the energy levels and electronic transitions mentioned later, I can’t even understand them.

Only now did he realize that he was still a scumbag. It seems that we still need to study harder!

When Yu Yifeng walked out of the conference room in disgrace, he looked at Yuriko walking by and pulled her unconsciously. He suddenly felt that it seemed inappropriate and quickly let go.

Yu Yifeng was a little embarrassed: "Uh... I told you a long time ago that I would treat you to dinner, just tonight. I still have some questions to ask you."

Yuriko was stunned, of course she remembered this meal. When she sent the Gauss rifle over, Yu Yifeng said he wanted to treat her to dinner, but it took him half a year and even lost her Gauss rifle... According to the interest rate, it would take at least two meals to pay it off. Bar?

Thinking of this, she frowned unhappily.

Yu Yifeng didn't guess that she had so many thoughts, so he walked directly towards the cafeteria. Yuriko, after humming in a low voice, could only follow closely.

"Let me ask, will there be mass loss in chemical reactions?" Yu Yifeng asked as he walked.

Yuriko said angrily: "Of course, isn't this common sense... But according to the level of nine-year compulsory education, you really don't know this. What teachers teach is the conservation of elements before and after chemical reactions, including mass."

Yu Yifeng smiled bitterly and said: "This is indeed the first time I have heard of this point of view..."

When it comes to such serious topics, Lily Zi no longer laughs at Yu Yifeng: "Alien materials have brought us a lot of inspiration, and they have also corrected many of our conceptual errors. Many scientists are working hard to find out, and improve our scientific theories.”

Yu Yifeng also nodded and said: "We are still in a state of half-understanding of the universe. Especially me, I still need to learn more theoretical knowledge, and I need to ask you for more advice in this regard."

Seeing that Yu Yifeng was sincerely asking for advice, Bai Hezi stopped being pretentious and said directly: "When a chemical reaction occurs and energy is released, an equivalent amount of mass must be lost. This is correct!"

"But because the energy released by most chemical reactions is far less than the energy released by common nuclear reactions. Therefore, the mass loss of chemical reactions is often so small that it cannot be measured by the most sophisticated instruments and can only be measured by the energy released by the reaction. Extrapolate.”

"Let me give you an example. The explosion of 1 mole of nitroglycerin can produce 2,700 kilojoules of heat. The mass loss before and after the reaction is 3.074*10^-8 grams, which is very small. It can also be ignored under normal circumstances..."

The two people walked into the cafeteria and chatted about this strange topic while ordering food. However, this seems to be a common thing in the cafeteria. The men and women coming and going around are all talking about science and related things. I didn’t even hear any other topics!

Yu Yifeng pricked up his ears and listened for a while, covering various topics such as electromagnetism, high-energy batteries, and nuclear energy. It seems that this scientific wave is quite powerful, and he himself enjoys this trend very much.

Yu Yifeng suddenly realized that all Lily Zi ordered were cheap vegetarian dishes. He quickly said: "Are you losing weight? Just order whatever you want, don't be polite to me!"

Yuriko was stunned. She was thinking about various scientific problems in her mind just now, but she actually didn't react. She thought everyone would eat what they had as usual.

Unfortunately, she is really a bit poor and a standard foodie. She can't stand the temptation of high-end luxury food. Almost all of her monthly salary goes into her stomach, so she often has to eat vegetarian food at the end of the month.

Thinking that today was Yu Yifeng's treat, she became less polite and pressed her fingers randomly on the computer screen, "This, this... and this!"

Yu Yifeng's eyebrows twitched. Sea crayfish, crab roe rice cakes, and kelp sushi were all very expensive. But I was surprised for a moment. He is a typical representative of wealthy people. His salary is the highest on the Noah. He can't spend it all at ordinary times, so he just eats what he eats... Of course, he still follows the new currency system. , do not make specializations.

"So... will the battery invented by Mr. Felix bring about a qualitative change in the energy system?" Yu Yifeng continued to ask while sitting at the dining table.

Yuriko looked at the sumptuous meal in front of her and said with satisfaction: "Of course, life will be much more convenient. From now on, mobile phones only need to be charged once a month; cars can run more than 10,000 kilometers on a single charge..."

"No, no, no!" Yu Yifeng waved his hand quickly, "I am referring to the military aspect. Can we use it to create laser weapons or particle beam weapons?"

Yuriko thought while enjoying the food. Obviously, Yu Yifeng's sumptuous meal had a good effect.

She said vaguely: "Theoretically, it's barely feasible, but it requires a suitcase-sized battery that only has the energy for one or two shots. To make the weapons you mentioned, we need batteries with higher energy density." "

"The most advanced battery is a nuclear energy battery or some superconducting battery. The radioactive isotope batteries we can currently produce in the laboratory use strong radioactive elements such as plutonium-238 and curium-244. They will slowly decay and generate electricity... …At least hundreds of times more powerful than the best chemical batteries!”
