Empirical evidence is the information received by means of the senses, particularly by observation and documentation of patterns and behavior through experimentation.

Empirical research is research using empirical evidence.

An emulsion is a mixture of two or more liquids that are normally immiscible (unmixable or unblendable) owing to liquid-liquid phase separation.

Paints in which the binder is dispersed in water. The paints dry as soon as the water evaporates and the emulsified droplets of resin join together to form a solid film.

Space bounded by floors, bulkheads and/or decks that may have doors, windows or other similar openings.

An encoder is a sensor which turns a position into an electronic signal.

An endothermic process is any process with an increase in the enthalpy H (or internal energy U) of the system.

Wärtsilä and Becker Marine Systems jointly developed the Energopac system. With both the propeller and rudder design integrated, each Energopac...

In physics, energy is the quantitative property that must be transferred to an object in order to perform work on, or to heat, the object.

Energy resources bring with them great social and economic promise, providing financial growth for communities and energy services for local economies.

Energy accounting is a system used to measure, analyze and report the energy consumption of different activities on a regular basis. This is done to improve energy efficiency, and to monitor the environment impact of energy consumption.

Energy aggregation is when entities partner together to buy energy from developers, at smaller volumes while retaining the economic advantages of a high-volume purchase.

An energy amplifier is a novel type of nuclear power reactor, a subcritical reactor, in which an energetic particle beam is used to stimulate a reaction, which in turn releases enough energy to power the particle accelerator and leave an energy profit for power generation.

Nanotechnology, a relatively new field of science and engineering, has shown promise to have a significant impact on the energy industry.

An energy audit is an inspection survey and an analysis of energy flows for energy conservation in a building.

Energy bars (candy bars) are supplemental bars containing cereals and other high energy foods targeted at people who require quick energy but do not have time for a meal.

In 2001 Belgian shipowner Exmar and US charterer Excelerate Energy worked together with Korean shipbuilder Daewoo Shipbuilding & Marine Engineering (DSME) to develop a flexible solution for the discharge of LNG.

An energy carrier is a substance (fuel) or sometimes a phenomenon (energy system) that contains energy that can be later converted to other forms such as mechanical work or heat or to operate chemical or physical processes.

The Energy Catalyzer (also called E-Cat) is a claimed cold fusion reactor.

In relativistic classical field theories of gravitation, particularly general relativity, an energy condition is one of various alternative conditions that can be applied to the matter content of the theory when it is either not possible or desirable to specify this content explicitly.
