The Mpemba phenomenon illustrates a strange curiosity of physics: sometimes, hot water freezes faster than cold water. As surprising as it may seem, this phenomenon...
When a food item stings or burns, it is often due to a molecule called capsaicin, found in peppers. Essentially, this substance tricks our body...
Glass is essentially made of molten sand, called silica, combined with other substances like sodium carbonate (soda) or calcium carbonate to facilitate its production. Unlike...
The choice of red in Marie Curie's notebooks was not a coincidence. This color held a certain symbolic importance for her: it evoked both her...
When you heat water, the molecules absorb energy and start to move faster and faster. At a certain point, some molecules gain enough energy to...
