Learn Python Effectively - With a Program, Practice, and a Tutor

It's all about learning patterns. Many AIs simply look at large volumes of text and learn a certain structure and sequence of language. If the user's request is related to the humanities, then there will be no problem. But with the exact sciences, it's more difficult: AI has learned to understand that a problem requires a numerical answer, and not that this answer must be calculated independently. This is why neural networks need additional training.

Developers quickly caught on: for example, the ChatGPT-o1 model, which was released this summer, already copes with most Olympiad problems in mathematics. In addition, sometimes AI is trained on incorrect reasoning, so artificial intelligence was trained to correct itself. This progress is already noticeable.

AI goes beyond its science — optimization, mathematics, data science — and penetrates into other areas: chemistry, biology, physics, astronomy, climatology. If we accumulate enough digital data, we can build predictive AI models with sufficient accuracy. Artificial intelligence can also work on hypotheses that were previously physically impossible to test due to the large amount of data.

In 2024, the Nobel Prize in Chemistry was awarded to scientists who used AI to solve the complex problem of predicting protein structure. The AlphaFold2 algorithm was able to predict the structure of almost all known proteins. This discovery will improve diagnostics, help create new biotechnologies, and combat antibiotic resistance.

What is rounding and why is it needed?
Rounding off numbers can be defined as replacing one number with another that is approximately equal to the first with a certain accuracy. Examples of rounding off:
