The theme of science and technology is vast and encompasses many fields and individuals. It's impossible to say definitively who is "most closely related" without more context.

To narrow it down, we need to consider what aspect of science and technology you're interested in. For example:

* Specific scientific disciplines: Are you interested in biology, physics, chemistry, etc.? Then a scientist specializing in that field would be most closely related.

* Technological innovations: Are you interested in specific inventions, like the internet or the telephone? Then the inventors of those technologies would be most closely related.

* Philosophical and ethical implications: Are you interested in the broader impact of science and technology on society? Then philosophers, ethicists, and social scientists might be more relevant.

Here are some examples of individuals who are closely related to the theme of science and technology:

* Scientists: Albert Einstein, Marie Curie, Isaac Newton, Charles Darwin, Rosalind Franklin, Stephen Hawking

* Inventors: Thomas Edison, Nikola Tesla, Alexander Graham Bell, Tim Berners-Lee, Steve Jobs

* Engineers: Elon Musk, Jeff Bezos, Sergey Brin, Larry Page

* Philosophers: Karl Popper, Thomas Kuhn, Hilary Putnam

* Science fiction authors: Arthur C. Clarke, Isaac Asimov, Ursula K. Le Guin

In conclusion, the answer to your question depends heavily on what specific aspect of science and technology you're interested in. Provide more context, and I can give you a more accurate and specific answer.
