Albert Einstein was right about his calculations

4 everyday objects that Einstein had a hand in making

Albert Einstein is rightly famous for developing the foundations of general relativity, which revolutionized our understanding of space, time and gravity. The principle of relativity has shown us that mass and energy are equivalent quantities that are related to each other. He formulated this fact in his equation E = mc², the most famous equation in history.

But relativity is only part of the amazing legacy that the German physicist left us. He was just as resourceful when it came to the physics of atoms, molecules, and light. Nowadays we encounter technological memories of his genius wherever we look. ("10 Things You (Probably) Did Not Know About Einstein")

Here we have brought together a few everyday products that embody Einstein's scientific contributions beyond the theory of relativity.

Albert Einstein and the invention of paper towels

The invention of paper towels goes to the account of the Scott Paper Company of Pennsylvania. They introduced the disposable product in 1907 as a hygienic alternative to cloth towels. In his very first article ever published, Einstein analyzed the so-called wicking effect: the phenomenon that causes paper towels to suck up liquid even though gravity tries to pull them down.

This process also ensures that hot candle wax is drawn into the wick (hence the name). This property is also called capillary action. It is responsible for ensuring that the sap can rise up in a tree and also reach the upper branches, and that ink flows into the tip of a fountain pen. Einstein's paper, published in 1901, attempted to explain how this attraction worked. It wasn't a particularly good attempt, as he himself later admitted. At the time, he argued that water molecules were attracted to the molecules in the walls of pipes by a force similar to that of gravity. However, this is not the case.

Nonetheless, his first publication demonstrated that Einstein already accepted the idea of ​​atoms and molecules - their existence was still considered controversial at the time. Because the tiny, hypothetical particles of mass were far too small to see or measure, many older and respected scientists claimed that they could not be part of rigorous science.
