Did you know ? A percentage is a hundredth of a whole. It is a way to express a part of a whole (ie a fraction) using a whole number. Writing e.g. "45%" ( 45 percent ) is actually just an abbreviation for the fraction 45/100, i.e. decimal number 0.45. The name comes from per cento, meaning (belonging to) a hundred.

Did you know ? Eukleides of Alexandria, most commonly known as Euclid, was an ancient Greek mathematician. We know little about Euclid's life. There is an opinion that he lived during the time of Ptolemy I. and perhaps he laid the foundations of mathematical research in the Alexandrian Museion. Euclid studied at the Platonic Academy in Athens and later worked in Alexandria.

Did you know ? Thermodynamics is a field of physics that deals with the study of thermal and thermodynamic processes, i.e. processes related to thermal energy, heat engines, temperature, pressure and volume. Thermodynamics helps us understand how heat is transferred, how heat engines work, and how air conditioning and refrigeration systems work. The laws of thermodynamics are used in many fields, from industry to medicine.
