= Quantum mechanics experiment
Atoms exist and last for a long time, while in <Maxwell's equations>[classical electromagnetic theory punctual] orbiting electrons should emit radiation quickly and fall into the nucleus: https://physics.stackexchange.com/questions/20003/why-dont-electrons-crash-into-the-nuclei-they-orbit
In other sections:
* <black-body radiation experiment>{child}
* <Einstein solid>{child} experiments, which are analogous to black body radiation experiments
* <emission spectrum>
* <electron diffraction experiments> such as:
* <Davisson-Germer experiment>{child}
