An atom is simply too small to deflect visible light waves, which means it won’t show up under even the most powerful light-focusing microscopes, Oncel said. Are we all made of atoms?

WebOct 19, 2016 · In the early 20th century, we weren't able to visualize reactions of tiny matter. We didn't doubt they were there, but we weren't sure of the details. Now we are, says astrophysicist Marcelo Gleiser. WebEven if we can't see atoms with our naked eye, properties of matter such as color, phase (e.g., solid, liquid, gas), and even smell come from interactions on an atomic level.
