Shulou(Shulou.com)11/24 Report--

Everyone must have been brushed by ChatGPT recently, as if it is powerful and omnipotent.

But, it doesn't matter, the Physics Society will do it. Today, let's test the literacy of its physical knowledge.

1. Introduction of ChatGPT ChatGPT (full name: Chat Generative Pre-trained Transformer) is an artificial intelligence chat robot program developed by OpenAI and launched in November 2022. The program uses a large language model based on GPT-3.5 architecture and is trained through reinforcement learning.

At present, ChatGPT still interacts with text. In addition to being able to interact through human natural dialogue, it can also be used for relatively complex language tasks, including automatic text generation, automatic question answering, automatic summarization and other tasks. For example, in the aspect of automatic text generation, ChatGPT can automatically generate similar text (plays, songs, plans, etc.) according to the input text, and in the aspect of automatic question answering, ChatGPT can automatically generate answers according to the questions entered. It also has the ability to write and debug computer programs.

ChatGPT picture, let it introduce itself.

So, after the brief introduction is done, let's officially enter our physics exam time.

2. physical knowledge assessment let's test it slowly from simple to complex.

Junior high school physics knowledge:

I was wrong at the beginning, and it seems that ChatGPT is not good either. The correct answer should be: size, direction and action point. Let's move on.

This answer is far from satisfactory, but these two questions show that its junior high school knowledge reserve is OK. What about the ability to use knowledge?

A choice question and a calculation question are also answered. It seems that the knowledge of junior high school can not defeat it.

High school physics knowledge:

Upgrade the difficulty, then enter the high school knowledge stage now.

Or first try its basic knowledge reserve, but this is no problem. But in high school, the ability to derive formulas should be improved to see if it works.

And look at its answer.

It can only be said that it is still unsatisfactory (ignoring the mistakes made by the editor because of carelessness), and it did not answer correctly in the end.

The correct answer should be:

Let's take a look at its knowledge of electromagnetism.

Keep asking it.

Ask again.

Not bad, it seems that it still has some logical thinking.

Then go on with the intensity!

Knowledge of college physics:

You may not know much about physics courses, but you must have heard of them. The editor will give you a brief summary of what physics courses a physics major is going to take.

Mechanics, optics, electromagnetics, heat: these four courses are also known as "general physics", commonly known as general physics, these four courses undertake a certain expansion of the knowledge learned in senior high school and junior high school, which is equivalent to the basic knowledge.

Four great mechanics (but not four kinds of mechanics): theoretical mechanics, electrodynamics, quantum mechanics and statistical mechanics. These four courses are the top priority for undergraduates majoring in physics. To borrow my teacher's "joke": if a person engaged in physics can not understand the four mechanics, then do not say that he is engaged in physics.

The four major mechanics teaching books actually have a very special course: atomic physics. It is like a bridge between general physics and the four great mechanics, so it has been retained in college courses.

Then you will focus on your study according to your research direction and interest, for example, condensed matter majors will choose solid-state physics and semiconductor physics.

Okay, that's all the nonsense. Let's get to the point.

Ha, failure, it should be that it does not know the physical meaning of the Lagrange equation. You forgot, too? Take a look at this: the principle that controls all the laws of motion: the principle of least action. (you will be better than Chat GPT after reading), go on.

Let's switch.

Well, the code written is correct, and it knows.

Emmm, the format is not quite right, but its description is more accurate. The correct answer should be

Finally, ask him a question.

It writes the Maxwell equations under active vacuum, and there is no problem. Lorentz gauge is a classic problem in electrodynamics. You can refer to teacher Cao Zexian's speech: Cao Zexian | electromagnetism / electrodynamics: phenomena, techniques and ideas (part two). The editor will not repeat it here.

Well, the exam is over, and the editor's evaluation of it is: a little high-minded and low-skilled, following others. Because of its huge data set, the reserve of physical knowledge is very large, far more than ordinary people can hold, but its logical ability and discrimination ability is not so perfect.

3, "learning" ability assessment can be seen before, although its logic is very poor, but the level of knowledge is good, then its learning ability? Let's flirt and test it.

It seems that it really understands, let's ask under another name.

It seems that it understands, but it doesn't understand much. Let's change the math problem.

Let's change the subject a little bit.

The editor crashed and it was wrong at first, but it still understood the process of calculation. Generally speaking, it has the ability to learn, but not much so far.

Note: the testing process of the editor is continuous and carried out in the same window.

4. Small tidbits

Give it a like.

To sum up, we have to say that Chat GPT brings us a great surprise: it does interact through human natural dialogue, and can be used for relatively complex language tasks such as automatic text and code generation. But it still has great limitations, for mathematical calculation, brain teasers and other areas that require strong logic, will make mistakes frequently. And it sometimes gives what it calls the right answer, which is very difficult for people in non-professional fields to tell (do you think its Schrodinger equation is correct? In short, it's a good tool at the moment, but don't rely too much on it!
