    st.header("📊 What is Data?")
    st.write("""
        Data refers to raw facts, figures, or information that can be analyzed or processed to derive insights. 
        It comes in various forms such as numbers, text, images, or even sounds. Data is everywhere around us - 
        from the text messages we send to the clicks on websites. Data can be structured (like tables and spreadsheets) 
        or unstructured (like social media posts, emails, etc.). At its core, data represents the "raw material" 
        that helps us understand the world and make informed decisions.

    # What is Science?
    st.header("🔬 What is Science?")
    st.write("""
        Science is the systematic study of the structure and behavior of the physical and natural world 
        through observation, experimentation, and analysis. Scientists use the scientific method to hypothesize, 
        test, and analyze data to understand how the world works. The goal of science is to uncover patterns and 
        relationships that can explain phenomena and predict future outcomes.

    # Combining Data and Science: Data Science
    st.header("🔍 How Data and Science Come Together: Data Science")
    st.write("""
        When we combine data and science, we get **Data Science**. Data Science is the field that uses scientific 
        methods, algorithms, and systems to extract knowledge and insights from data. It applies techniques from 
        statistics, computer science, and domain expertise to interpret large datasets and uncover valuable insights. 
        The process typically involves collecting and cleaning data, performing exploratory data analysis, building 
        models, and communicating results to make decisions or predictions.

        In simple terms:
        - **Data** is the raw input.
        - **Science** provides the methods and tools for analyzing this data.
        - **Data Science** is the application of science to data, turning it into actionable insights.

        The beauty of Data Science is that it allows businesses, organizations, and individuals to make smarter decisions based on data. 
        Whether it’s understanding customer behavior, predicting future trends, or solving complex problems, data science empowers us 
        to uncover hidden patterns in the data that would be difficult to see otherwise.

    # Understanding Artificial Intelligence (AI)
    st.header("🤖 What is Artificial Intelligence (AI)?")
    st.write("""
        Artificial Intelligence, or AI, refers to the simulation of natural intelligence in machines. AI allows machines to 
        think, learn, and perform tasks that would typically require natural intelligence. 
       \n These tasks include decision-making, speech recognition, visual perception, and language translation. 
        AI is the broader concept, and it includes several subfields, like machine learning and deep learning.

    # Explaining Machine Learning
    st.header("💻 What is Machine Learning?")
    st.write("""
        Machine Learning (ML) is a subset of AI. Machine Learning is a tool which has ability to mimic the Natural Intelligence.
       \n ML requires the data and algorithm in which it uses relationship function between data and algorithm.
        \nFor example, email services use ML to filter spam emails based on patterns learned from previous emails.

    # Deep Learning Explained
    st.header("🧠 What is Deep Learning?")
    st.write("""
        Deep Learning is a specialized branch of machine learning that focuses on using neural networks with many layers 
        (hence the term "deep") to analyze complex patterns in large datasets. These neural networks are inspired by the structure 
        and function of the human brain. 
             \nDeep learning has led to breakthroughs in areas like image recognition, natural language processing, 
        and speech recognition. 
             \nFor example, deep learning is the reason we have virtual assistants like Siri or Alexa.

    # Introduction to Generative AI
    st.header("🎨 What is Generative AI?")
    st.write("""
        Generative AI refers to algorithms that can generate new content such as text, images, and videos. 
        Unlike traditional AI systems that focus on analyzing data and making decisions, generative AI focuses on creating new, original data. 
        \nThis can include generating realistic images from text descriptions or writing new music based on patterns learned from existing songs. 
        \nExamples of generative AI are models like GPT-3, which generates human-like text, and DALL-E, which generates images from textual descriptions.
