How did physics change modern technology?
Well, it certainly developed better products...
Physics has helped us innovate more productive, efficient, and better products in general. Due to a deeper understanding of physics, we could invent better microscopes, telescopes, and such. Thanks to physics, we have invented technology to find out gravitational waves and predict the existence of black holes, dark matter, and dark energy.
Of course, some people will think that it was all engineering, but remember that engineering requires the application of physics in order to create machines.
