A field, practice, or body of knowledge can reasonably be called pseudoscientific when it is presented as consistent with the norms of scientific research, but it demonstrably fails to meet these norms. Assertion of claims that a theory predicts something that it has not been shown to predict. 2  Scientific claims that do not confer any predictive power are considered at best conjectures, or at worst pseudoscience (e.g. Ignoratio elenchi).
Condensation is the process by which water vapor in the air is changed into liquid water. In other words, the water in the air, a gas known as water vapor, from your hot shower cooled when it met the surface of the cold mirror. This caused the water vapor to condense, or turn into its liquid form.
Condensation can describe the act of making something shorter, like the condensation of the unabridged dictionary to one that is geared to elementary school students. In addition to meaning shortening, condensation also describes the act of changing a gas to a liquid or solid. You have seen this in summer, when the outside of your glass of ice water feels wet in your hand. As the heated air reaches the cold water, the surface of that water begins to evaporate, but it turns back to liquid. This moisture is also called condensation.
