What instruments made scientific discoveries possible?

Scientific discoveries have been made possible by a variety of instruments, including the microscope, which allowed for the observation of microorganisms and cells, and the telescope, which expanded our understanding of the universe. Other key instruments include the spectrometer, which analyzes light spectra to uncover chemical compositions, and the particle accelerator, which enables the study of subatomic particles. Each of these tools has significantly advanced knowledge across disciplines, from Biology to astronomy and physics.
