No, I don't think only scientists can invent new things. Many inventors aren't scientists. They come from different backgrounds, like art or engineering. For example, the Wright brothers, who invented the airplane, weren't scientists. They were bicycle mechanics. Invention often comes from practical experience and creativity, not just scientific knowledge.

Yes, I think scientists are more likely to invent new things. They have the technical knowledge and understanding of complex concepts. Plus, they have access to research facilities and funding, which helps them experiment and develop new ideas. Their scientific training allows them to approach problems systematically, leading to more technological advancements.

It depends on the invention. Sometimes, collaboration between scientists and non-scientists leads to great inventions. Some inventions need scientific knowledge, while others don't. The nature of the invention determines if scientific input is necessary. Often, interdisciplinary teams create the most innovative solutions by combining creativity, knowledge, and opportunity.
