Chapter 1718 Turing Machine

In the "01" project laboratory of the cement building near the Dongfang Capital Arsenal, a female researcher is defending in front of the project committee.The "01" project she was in finally started formal research after accumulating enough early technology and talent reserves.

"Assuming that there is a machine that can be used to simulate the process of a computer using pen and paper to perform mathematical operations, any problem that can be solved by an algorithm can be solved by this machine."

"This machine consists of four parts, an infinitely long paper tape, which is divided into small grids lined up one by one, and each grid is marked with '0' or '1'."

"A reading and writing needle that can move left and right on the paper tape. It can read the symbols on each grid and change the symbols of the grid at the same time. The function is to read and output."

"A state register can save the current state of the machine, and there is a special state, which is the shutdown state, to prevent an infinite loop."

"A control system, which can determine the next action of the read-write needle according to the symbols read by the machine and the state it is in, and change the value of the status register."

"I will call a machine that meets the above characteristics an 'intelligent machine'. If this machine can be used to solve various mathematical problems such as the calculation of non-linear equations and meteorological observations of the artillery table, it will save us a lot of money." Calculators, and the calculations are faster and more accurate, and they can even perform mechanical addition and trigonometric calculations around the clock..."

Liu Rushi stopped talking, wondering if the project committee understood what she was saying.

She is no longer the woman who only knew poems and songs before, but now she is a double Ph.D. in Mathematics and Physics of Jingshi University, and a senior researcher of the 01 project.

Chu Yun ordered the 01 project to be carried out a long time ago, but the electrical engineering technology and other basic theories were not yet mature at that time, so Chu Yun recruited a group of students from the School of Mathematics and the School of Physics in the Imperial University Hall, and asked them to simultaneously Formal research can only begin after obtaining doctorates from both faculties.

Now technology and talents are gradually in place, and the project is preparing to be put on the agenda.

The 01 and 0 of the 1 project are the signs of the binary world, the cornerstone of a virtual world different from the real world.

The scientists on the project committee do not have talents in the computer field, such as Turing or von Neumann, but only scientists, statisticians or physicists who invented difference machines and punch tabulation machines.

The reason is very simple. General-purpose computer technology is the technology of the middle and late 20th century, and Chu Yun can't use the system to recruit people from that era for the time being.

However, don't underestimate machines such as difference machines and perforated tabulation machines. These are the first products that humans tried to use machines to solve mathematical problems.

"Let the machine read the content by itself, and then process it according to the recognition results. Can this kind of 'smart machine' be physically realized and used to solve the nonlinear equations of the ejection table?" Scientist of the project committee they asked.

"We can use electrical energy and electronic components as the physical carrier of this machine, and use logic circuits to perform direct logical operations instead of the usual digital arithmetic to give it a soul. Using binary instead of the usual decimal, binary Adoption will greatly simplify the logic circuit of the machine. Furthermore, the use of capacitors as memory is reproducible and avoids errors. We may need a large number of vacuum tubes and crystal diodes, resistors, capacitors, relays, and circuit switches.” Liu Rushi said.

Some of the earliest circuit scientists on the project committee heard that Liu Rushi seemed to have found a way to turn "smart machines" into reality, and whispered in private to discuss its feasibility.

It seems to be a feasible solution to solve mathematical problems from the physical logic level by stacking a large number of electronic components, and to make the machine have "logic".

"Perhaps your idea may be in line with the original intention of the military master to set up the 01 project plan. The military master is on his way back from the west, you can form a more specific project plan, and wait for the military master to come back to the capital and ask him and the project. Each committee submitted one copy. According to you, a large number of vacuum tubes, crystal diodes and other electronic components are used. Our research on these electronic components has just achieved results.” An English physicist named Fleming said .

The person summoned by Chu Yun to this world is also a famous scientist. He discovered the right-hand rule used in physical electromagnetism and invented the diode, all of which can be included in textbooks.

"I will submit a plan as soon as possible." Liu Rushi replied.

"It's good for young people to be active in thinking. Our project has accumulated a group of young people in their 20s. They have a lot of knowledge reserves. The funds for the project should be in place as soon as possible, and they can't be wasted. The most active thinking in their lives years."

After this defense, the members of the project committee reached a consensus.

When Liu Rushi came out of the laboratory of the arsenal, Xiao Xiuer was waiting outside with a child in her arms.

"Sister Xiao, why are you here?" Liu Rushi asked in surprise.

"Master Master and the two elder sisters are going to arrive in Tianjin Wei. I plan to pick them up. Do you have time?" Xiao Xiuer smiled and said to Liu Rushi who came out.

"They finally came back from Europe? I'm writing a report now, and it's okay to go to Tianjin Wei to work temporarily." Liu Rushi replied.

"How's your research on 'smart machines'?" Xiaoxiuer asked.

"It's okay, it's only used to solve math problems at present, but I always feel that intelligent machines will have greater uses in the future." Liu Rushi said.

"If there is such a machine, it may be able to solve medical or other problems." Xiao Xiu'er said, "It would be great if it could draw graphics. This kind of intelligent machine can be used to make maps or statistical tables, say There might be a lot more to it.”

Xiao Xiuer heard Chu Yun talk about the future of computers, but Liu Rushi didn't know the existence of the system, nor what the future of computers would look like.

"Is Chen Yuanyuan on vacation at the Capital University?" Xiao Xiu'er asked again.

"She is about to graduate, so she should have a lot of time, why don't I ask her if she can go." Liu Rushi flicked the ends of her hair.

"What does she think about in the future? Do she want to continue her studies, or do she want to go into business, or find a way to become an official?"

"I don't know what she thinks. She studies chemistry, so she should be a researcher..."
