Data Science is the study of data to extract meaningful insights for businesses. It is a multidisciplinary approach that combines principles and practices from the fields of mathematics, statistics, artificial intelligence, and computer engineering to analyze large amounts of data. It helps ask and answer questions like what happened, why it happened, what will happen and what can be done with the results. 

We are overwhelmed with data. The amount of data in the world and in our lives seems ever increasing - and there's no end in sight. As the volume of data increases, the proportion of it that people understand decreases alarmingly. Lying in all this data is information, information that requires data scienctists for it to be known. 
This roadmap aims to guide anyone interested in this field and with an overall goal of giving meaning to data.
### 1. **Fundamental Knowledge:**
   - **Mathematics:** Focus on statistics, probability, linear algebra, and calculus.
   - **Programming:** Master at least one programming language. Python and R are highly recommended in the field of data science.

### 2. **Basic Tools:**
   - **IDEs:** Jupyter Notebook, RStudio, or similar.
   - **Version Control Systems:** Git & GitHub.
   - **Data Manipulation Libraries:** pandas, NumPy, dplyr, or similar. Each language - Python and R has libraries which ease data manipulation.
   
### 3. **Data Collection and Manipulation:**
   - **Database Management:** SQL is a must. Familiarize yourself with NoSQL databases like MongoDB as well.
   - **Data Cleaning:** Learn techniques to clean and preprocess data to prepare it for analysis.

### 4. **Data Analysis:**
   - **Exploratory Data Analysis (EDA):** Get comfortable with plotting libraries like Matplotlib, Seaborn or ggplot2.
   - **Statistical Analysis:** Hypothesis testing, regression analysis, etc.

### 5. **Machine Learning:**
   - **Supervised and Unsupervised Learning:** Understand the core algorithms, from linear regression to clustering.
   - **Frameworks:** Scikit-learn, TensorFlow, PyTorch, or similar.

### 6. **Deep Learning:**
   - **Neural Networks:** Familiarize yourself with the basics of neural networks, CNNs, RNNs, and the like. Depending on your use case, research on which neural networks are appropriate to your specific needs.
   - **Advanced Frameworks:** Get hands-on experience with frameworks like TensorFlow or PyTorch.

### 7. **Big Data Technologies:**
   - **Frameworks:** Hadoop, Spark.
   - **Streaming Data:** Learn how to work with streaming data using tools like Kafka.

### 8. **Data Visualization:**
   - **Tools:** Tableau, Power BI, or programming libraries like Matplotlib and Seaborn.

### 9. **Specializations:**
   - Dive deeper into areas of interest such as NLP, reinforcement learning, or anomaly detection. Data Science is a broad field and you have a range of options to choose from when it comes to specialization. Pick an area that interests you and learn as much as you can.
   
### 10. **Projects and Portfolio Building:**
   - **Real-world Projects:** Engage in projects to solve real-world problems.
   - **Portfolio:** Build a strong portfolio to showcase your skills and experience.
   
### 11. **Networking and Community Participation:**
   - **Meetups and Conferences:** Attend data science meetups, webinars, and conferences. 
   - **Online Communities:** Engage in online forums and communities like Kaggle. Lux Academy is an example of such communities where you can connect with like minded individuals, easing the learning process.

### 12. **Continuous Learning:**
   - **Online Courses and Certifications:** Keep updating your skills. Stay updated with the latest research papers, books, and other resources. Tech is an ever growing field and thus try to keep abreast with changes and new technologies.  

This roadmap is designed to provide a step-by-step progression, ensuring a solid foundation is built before moving onto more advanced topics. It's a blend of acquiring theoretical knowledge, practical skills, and engaging with the data science community to keep evolving in your data science journey.
