Q: Welcome to this episode of KPIT STEM Dialogues. We are extremely happy and honored to have with us today Dr. Bjarne Stroustrup. Dr. Stroustrup, welcome to the show, and thank you for accepting our invitation.

Bjarne Stroustrup: Thank you. It’s a pleasure to be here.

Q: Dr. Stroustrup, you have an impressive background, weaving together work in academia and industry. Currently, you’re a professor of computer science at Columbia University. Before that, you were with Morgan Stanley, Texas A&M, and Bell Labs. Could you tell us about your early education and what motivated you to pursue a career in science?

Bjarne Stroustrup: I grew up in Aarhus, Denmark, in a working-class family. I attended the worst primary school in town, but I was always curious and interested in learning. I had various jobs to earn pocket money, like delivering milk and newspapers. When I got to university, I found programming and machine architecture fascinating. I paid for my education by programming, and although education in Denmark is free, you still need to live, so it helped.

Q: Mathematics seems to have been a significant part of your early education. Was it your favorite subject?

Bjarne Stroustrup: Yes, mathematics was a favorite of mine. Initially, I thought of pursuing history, sociology, or philosophy, but I realized math was a better career choice. I signed up for mathematics at my local university. However, once I discovered programming and computer science, I knew that was my true calling.

Q: You have spoken warmly about your experience with Dr. David Wheeler at Cambridge University. Can you share how that influenced your career?

Bjarne Stroustrup: My time at Cambridge was transformative. Dr. Wheeler used a teaching method that involved discussing ideas and exploring alternatives rather than just delivering lectures. This approach taught me how to think critically and approach problems as a scientist and engineer. It was a significant shift from the classical education I received earlier.

Q: Can you tell us about the genesis of C++? What inspired you to create it?

The idea for C++ came from my need to combine the efficient hardware manipulation capabilities of C with the high-level features of Simula, such as classes and object-oriented programming. I started developing C++ at Bell Labs to build a distributed computer system. The initial version, called “C with Classes,” evolved into C++ as I added more features to meet the needs of my colleagues and myself.

Q: C++ has evolved significantly over the years. How do you manage to keep the language fresh and relevant?

It’s essential to listen to the community and understand their needs. I look at what people are doing with C++ and what they would like to do. We then work on improving the language by strengthening its good aspects and finding alternatives for what doesn’t work well. Compatibility is crucial; we aim to simplify the language’s use without breaking existing code.

Q: What are your thoughts on AI and its impact on programming?

AI and large language models have potential, but they have a long way to go before they can be fully trusted. They can handle routine tasks well, which frees up humans to focus on more complex problems. However, designing systems and understanding real problems still require human insight and creativity.

Q: How do your hobbies and interests outside of computer science contribute to your work?

Activities like running, reading history, and listening to music help me relax and think differently. They prevent burnout and provide a broader perspective. For example, I get some of my best ideas while running. It’s crucial to have a well- rounded life to sustain a long and productive career.

Dr. Finkel: My journey began with a passion for silicon over 50 years ago. As a teenager, I was fascinated by electronics and went on to study electrical engineering. This foundation led me to explore various fields, including neuroscience and entrepreneurship.

Q: You mentioned silicon as a significant part of your career. What makes silicon so special in the world of electronics?

Dr. Finkel: Silicon is extraordinary because it can be doped with small amounts of phosphorus or boron to introduce charge carriers, making it a semiconductor. This allows silicon to carry current, form PN junctions, and create transistors. Its versatility and stability have kept it at the forefront of technology, despite many predictions of its obsolescence.

Q: Let’s talk about lithium. Why is lithium so important in today’s technology?

Dr. Finkel: Lithium is the queen of batteries. It has the highest energy storage density per kilogram and the highest working voltage among metals used in batteries. Lithium-ion batteries are lightweight, can be discharged thousands of times, and maintain their charge well. This makes them ideal for mobile applications like electric vehicles and portable electronics.

Q: What are some key figures you mentioned about lithium?

Dr. Finkel: Lithium has an atomic weight of 7, making it the lightest metal. It provides a working voltage of 3.7 volts in batteries, compared to 2.5 volts for sodium and 2.2 volts for lead. This combination of light weight and high voltage makes lithium batteries exceptionally efficient.

Q: Hydrogen is another topic you are passionate about. Can you explain its potential and significance?

Dr. Finkel: Hydrogen is the green molecule of the future. It can be produced through electrolysis using renewable energy, resulting in zero carbon emissions. Hydrogen is abundant and can be used in fuel cells to generate electricity, heat, and water. It’s crucial for achieving net-zero emissions, especially in applications where high-density energy storage is needed, such as long-distance freight and steelmaking.

Q: You have also made significant contributions to neuroscience. Can you share some insights from your work in this field?

Dr. Finkel: My work in neuroscience includes founding Axon Instruments, which develops high-end scientific tools for brain research. One fascinating aspect of the brain is neuroplasticity, the ability to form new neural connections throughout life. This adaptability is fundamental to learning, memory, and recovery from injuries.

Q: What impact do you hope your work will have on future generations?

Dr. Finkel: I hope to inspire and educate the next generation of scientists and engineers. Interdisciplinary learning and innovation are crucial for solving complex global challenges. Whether through advancements in energy, neuroscience, or education, I believe in the power of science to drive progress and improve lives.

Q: Finally, what advice would you give to students pursuing careers in science and technology?

Dr. Finkel: Get a broad and solid education. Stay curious and open to learning across disciplines. The challenges of the future will require integrated solutions, so be prepared to think creatively and work collaboratively. And always remember, science is not just about knowledge; it’s about making a positive impact on the world.

Q: Your life has been an extraordinary journey, from studying under streetlights to becoming a renowned scientist. What lessons have you learned, and what advice would you give to young students?

Dr. Raghunath Mashelkar: My journey has taught me several important lessons:

Power of Ideas: It’s not the power of the budget that matters, but the power of ideas. Innovative thinking can compete globally, regardless of resources.

Risk-Taking: Embrace adventurous and audacious ideas. Failure should be seen as a First Attempt In Learning (FAIL).

Borderlessness: Interdisciplinary collaboration is crucial. Break down the borders between different fields of science and engineering.

Inclusion: Make high technology work for the poor. Science should help improve the lives of the underprivileged.

Continuous Improvement: Always believe that your best is yet to come. Keep striving for excellence every day.

Q: At the age of 80, you remain incredibly active. Can you describe a typical week in your life?

Dr. Raghunath Mashelkar: My weeks are filled with diverse activities.
