Mathematics (from Greek μάθημα máthēma, "knowledge, study, learning") is the study of such topics as quantity, structure, space, and change. It has no generally accepted definition.
Mathematics is a versatile art; it can be applied to widely different purposes. Math has no morality; it does not care what it counts or what it proves.

Imagine having gas stations with fuel pumps that harness solar energy to produce fuels – something akin to the process that plants use to make their own food. EU-funded scientists made major advancements in developing solar technology to turn carbon dioxide (CO2) into solar fuel, helping to reduce dependence on fossil fuels.
