Hello, and welcome to paper-to-podcast. Today we're diving into an exciting topic: Can Artificial Intelligence solve physics problems? Picture a robot sitting in your college physics class. That's a bit of a strange image, isn't it? But that's essentially the premise of a fascinating study conducted by Karen D. Wang and colleagues.
These researchers trained a language model AI named ChatGPT, based on the GPT-4 model, and set it to work on 40 problems from an engineering physics course. It was a bit like a high-tech version of an end-of-semester exam. The AI did pretty well, solving 62.5% of well-defined problems. Give it all the data it needs, and it's a regular physics whiz. But when it came to under-defined problems? Well, let's just say the AI didn't exactly ace that portion. Its success rate dropped significantly to 8.3%.
It appears that while the AI can identify the relevant physics concepts for problem-solving, it struggles when it has to make assumptions for missing data or construct accurate models of the physical world. It's like asking a chef to make dinner with only a potato and no recipe. Chances are you’re going to get a raw spud.
So, while AI is quite adept at solving textbook physics problems, it runs into trouble when faced with the ambiguity and complexity of real-world problems. If the future involves human-AI collaborations, we humans still have the upper hand when it comes to solving complex and uncertain problems.
The researchers put this AI model to the test by using 40 real-world physics problems, then grading its answers. They even tried to help it out with "prompt engineering," providing more specific instructions to see if it would avoid making the same mistakes. But despite their efforts, the AI still struggled with under-defined problems.
This study is fascinating in its exploration of AI’s ability to solve real-world problems, an area less explored in AI research. The researchers meticulously analyzed the AI's answers and identified three distinct failure modes. They also deserve kudos for using the ChatGPT interface, the way most students and teachers would use it, which adds practical applicability to the study.
Nonetheless, the research does have some limitations. The probabilistic nature of the AI algorithm can result in different answers for each question, adding variability to the analysis. Also, different versions of the algorithm could produce varied results, which makes the interpretation of findings, well, a bit tricky. And, unfortunately, the lack of repetitive testing means the conclusions drawn about the tool's performance are based on a single-pass evaluation.
This research could have far-reaching implications, particularly in improving AI tutoring systems in Science, Technology, Engineering, and Math education. The findings also suggest a new pathway in preparing students for a future where AI is more prevalent. By understanding the strengths and weaknesses of AI in problem-solving, educators can focus on teaching students key competencies such as accurately modeling problems and making deliberate decisions about assumptions and estimates. Additionally, this research can inform future human-AI collaboration frameworks, giving us a new perspective on how humans and AI can work together to solve complex real-world problems.
So, while our AI friend may not be ready to ace a college physics exam just yet, it's clear that it has potential. And who knows? With a little more study and a few more potatoes, it might just surprise us all.

Supporting Analysis
Imagine a robot taking a college-level physics course. Sounds wild, right? But that's pretty much what the boffins behind this study did. They let a language model AI named ChatGPT (based on the GPT-4 model) loose on 40 problems from an engineering physics course. Turns out, the AI aced 62.5% of the well-defined problems. Not bad, huh? But hold your applause. When it came to under-defined problems, where not all info was given, the AI's success rate dropped to 8.3%. Ouch! The AI was smart enough to identify relevant physics concepts for solving problems. But it struggled when it had to make assumptions for missing data or construct accurate models of the physical world. It's like giving a chef all the ingredients and a recipe - they'll probably cook up a storm. But if you just give them a potato and say 'make dinner', they might just hand you a raw spud. Basically, the AI is good at textbook problems but gets stumped when faced with real-world ambiguity. So, if the future involves human-AI collaborations, we humans still have the edge in handling complexity and uncertainty.
This research paper put a fancy pants AI model, called GPT-4, to the test by using it to solve 40 problems from a college-level engineering physics course. The problems were divided into two categories: well-specified problems where all the data was provided, and under-specified problems where some data was missing, just like in real life. The researchers then compared the AI's answers to the correct solutions to figure out where it messed up. They also tried to make the AI's job easier with a technique called "prompt engineering," where they provided more specific instructions. The goal was to see if this helped the AI avoid making the same mistakes. To keep things realistic, the researchers used GPT-4 in its ChatGPT form, which is the way most students and teachers would use it. They recorded all the AI's responses in a document for analysis. So basically, they had the AI take a physics test, then graded it.
What's most compelling about this study is its exploration of the AI's ability to solve real-world, under-specified problems, which is a less charted territory in AI research. This angle addresses a crucial aspect of AI application in problem-solving, as real-world problems often lack complete information. The research design, where they test ChatGPT's capabilities across different problem types, also stands out. This approach allowed for a more comprehensive assessment of the AI's problem-solving skills. The researchers followed best practices by clearly defining their research questions and methodology, and by analyzing failures in a detailed manner. This analysis led to the identification of three distinct failure modes of the AI. Additionally, the paper's commitment to ecological validity, choosing to use the ChatGPT interface instead of the API to mimic the way users would interact with the tool, highlights their attention to practical applicability. The use of a diversity of problem types also strengthens the validity of their findings.
The research has a few limitations that deserve consideration. First, the inherent probabilistic nature of the underlying algorithm in ChatGPT might produce different answers each time a problem is posed, adding variability to the analysis of its solutions. Second, different releases and incremental builds of the algorithm could further produce varied results, making the interpretation of findings contingent on the specific version of the algorithm used. Lastly, the lack of repetitive testing restricts our understanding of the tool’s stability and reliability in providing consistent solutions. The absence of this repetitive testing means any conclusions drawn about the tool's performance are based on a single-pass evaluation, which might not accurately reflect its true capabilities or limitations.
The research can be used to improve AI tutoring systems in STEM education. AI-based tools like ChatGPT could be used to help students identify relevant knowledge required for problem-solving, thus enhancing their understanding of conceptual knowledge. This could significantly change the way students approach homework or study for exams. The findings also suggest a new direction in preparing students for a future where AI is more prevalent. By understanding the strengths and weaknesses of AI in problem-solving, educators can focus on teaching students key competencies such as accurately modeling problems, making deliberate decisions about assumptions and estimates, and devising plans for data collection. Furthermore, the research can inform the development of human-AI collaboration frameworks, where humans and AI work together to solve complex real-world problems.
