34.

The logic of "and", in layman's terms, is the relationship of "and", and the two switches must be closed before the bulb will be lit, which is a kind of and relationship.

"And such an operation?" said the old man, breathing a little heavily.

As the most accomplished in yin and yang arithmetic on Qingling Island, he keenly felt what Cheng Li meant by posing this small logical spiritual path.

If it is really as Cheng Li said, he can use this logical spiritual path to express the three major yin and yang changes, then this is equivalent to the realization of big props.

It's just incredible!

So the old man hurriedly said: "Then what about the remaining two logics?

Cheng Li said unhurriedly: "Don't worry, I'll get a logical spiritual path right now-'Or Gate' spiritual path." ”

Then Cheng Li was on the ground, using a new batch of materials, and soon connected a new spiritual path.

Everyone around them poked their heads one by one, stretched their necks, widened their eyes, and stared at a new spiritual path that Cheng Li had made out on the ground.

In this spiritual path, a crystal wire is tied to a spirit stone, and both ends of the same way extend out.

One end is also connected to a spiritual lamp.

But the other end, after extending for a distance, suddenly branched into two crystal wires, and then connected two switches respectively, and finally merged into one crystal wire, which was also connected to the spiritual lamp.

If anyone on earth who has studied junior high school physics comes and looks at it, he will know that this is a parallel circuit.

In logic circuits, such a parallel circuit is also called an "or-gate" logic circuit.

Cheng Li watched everyone watch intently, and couldn't help but say proudly.

"This is the 'or door' logic path, and watch me demonstrate it to you. ”

"I turned both switches off and the lamp went out. Two yin is yin. ”

"I closed both switches and the lantern lit. Two yangs are yangs. ”

"I turn one switch off and then turn the other switch off, and the lantern will still be lit. That is to say, in this logical spiritual path, one yin and one yang are yang. ”

The old man suddenly exclaimed: "If this is the case, I understand! This is the logic of "or" in the three major yin and yang changes. ”

In the first series circuit built by Cheng Li, there is a "and" logic, when there is a yin and a yang, the bulb is off, so the output result is yin.

In the parallel circuit, there is an "or" logic, when there is one yin and one yang, the bulb is lit, so the output result is yang.

These two circuits represent two different logical processes.

Even if the old man had a feeling of sudden realization, the whole person was extremely excited.

"This ...... This...... It's the embodiment of the Great Dao!"

The people around were also in an uproar, some of them were shallow in yin and yang, and some were unclear, completely unconscious, and I don't know why others were so excited.

And some people who have profound knowledge of yin and yang, who can understand the truth, are extremely excited, but they also have many doubts at the same time.

"However, why is it that when someone is cultivating and realizes the Great Dao, there should be a brilliant vision, and it is born along with the visualization of the Great Prop, but after this spiritual path is built, it is mediocre, how can it be explained?"

"Yes, I don't understand, things that look very sparse and ordinary, can they really be the embodiment of the avenue when put together like this?"

In the midst of the surrounding discussions, Wang Tianyu was blushing, and with his yin and yang arithmetic attainments, he keenly felt the profound truth contained in Cheng Li's construction of this spiritual path.

But because of this, he felt more and more that he couldn't let Cheng Li continue to drum, so he cooperated with some doubts and spoke.

"That's right, if this is really the embodiment of the Great Dao, why is there no sound of the Great Dao, why is there no vision, this is too inconsistent with the way of heaven. I THINK THIS IS JUST SOME TRICKS, OPPORTUNISTIC MEANS!

Wang Tianyu spoke louder and louder, and finally said loudly: "When Cheng Li defined the meaning of those spiritual lamps and switches, they were all artificially given, not heavenly!"

Wang Tianyu is worthy of being one of the few people with the best arithmetic talent among the younger generation on Qingling Island. He quickly found the only gap that could attack Cheng Li.

But Cheng Li disagreed: "Mathematics is originally a discipline defined by man. It is a tool made by human beings to help explore the Great Dao! There is no artificial definition, and human beings understand the world by artificial definition. Only through this artificial definition and constantly fitting the Great Dao can this be the process of exploration! Could it be that you want the Great Dao to put the truth directly in front of you? It's ridiculous!"

Cheng Li's rebuttal was also very sharp, which suddenly made Wang Tianyu speechless.

"Also, my ultimate goal is to make a calculator that can do the math on my own, and I don't care if it's a big prop or not. ”

The old man admired it very much: "That's right, the result is the most important thing, if you can get the right result, then at least it means that your logical spirit path is in line with the avenue! As for whether the big prop is visualized, it doesn't matter at all, it's the old man's appearance." ”

Cheng Li said indifferently: "Some definitions of this logical spiritual path are artificially given, but the objective laws contained in it are natural, and they exist objectively in the first place, rather than being perceived by others, so it is normal to not have those so-called visions." ”

After Cheng Li finished speaking, he continued to connect a new circuit.

Of the three basic logic circuits, Cheng Li has completed the "AND gate" and "OR gate", and now there is still one NOT gate missing.

The construction of NAND gate logic circuits is special, and it is neither a series circuit nor a parallel circuit. On earth it can be achieved with an electromagnet.

Although there is no electromagnet here, there is also a magic weapon that produces magnetism as long as it is infused with spiritual power.

"Xiaochun, give me a meta magnet. ”

Yuan magnet is the lowest level of magnetic magic weapons, so it is also a very common thing.

So soon, Xiao Chun handed the Yuan Magnet to Cheng Li.

After Cheng Li took over the Yuan Magnet, he first passed the magnet and the spirit stone through the crystal line to form a completely closed spiritual path.

Then build an independent spiritual path above this spiritual path, which is a second spiritual path that combines spiritual lamps, spiritual stones, and another switch into a second spiritual path independent of the spiritual path below.

There is no communication between the two spiritual paths.

However, the switch of the upper spiritual path is close to the element magnet, so when the lower spiritual path switch is closed, the magnetic nature of the element magnet will pull down the switch of the upper spiritual path, so that the switch of the upper spiritual path is disconnected and the spiritual lamp is extinguished.

And once the lower spiritual path switch is disconnected, the element magnet loses its magnetism, and the upper spiritual path switch will return to closing, and the spiritual lamp will be lit.

"Well, this logical spiritual path is called 'NOT', which can also be called a reverser. Its role is to play a negative role.

"When I close the switch on the spiritual path below, the spiritual lamp on the spiritual path above goes out. That is, to input yang, to generate yin. ”

"And disconnecting the switch of the spiritual path below will instead make the spiritual lamp light up, that is, input yin and generate yang. ”

In this way, yin and yang are transformed in this spiritual path. From yin to yang, from yang to yin. ”

"This is a non-gate. ”

At this point, the three basic logic gates have been constructed. ”

"The next step is to use these three basic logic gates to form an addition machine!"
