1, An Enlightening View on the Generation and Transformation of Light, discusses the quantum and photoelectric effects of light.
2. The mathematical formula for calculating diffusion velocity is derived from a new method for determining molecular size.
3. The motion of small suspended particles in still liquid required by the theory of thermomolecular motion provides evidence that atoms do exist.
4. On electrodynamics of moving objects puts forward a new theory of space-time relationship, which is called "special relativity".
5. Whether the inertia of an object determines its internal energy is based on special relativity, which shows that mass and energy are interchangeable. Later, the most famous scientific equation was deduced: E=mc2.
