Archaeologist: (also called archaeologist) A person who studies human history and prehistory through the excavation of ruins and the analysis of artifacts and other physical remains. The remains range from housing materials and cooking utensils to clothing and footprints. The field that these people study is known as archaeology.
average: (scientific term) A term for the arithmetic mean, which is the sum of a set of numbers divided by the size of that group.
Watershed: (geology) A low-lying area, often below sea level, where water collects and deposits fine silt and other sediments at the bottom. Because these materials collect there, they are sometimes called watersheds or drainage basins.
B.C.: an abbreviation for Before Christ, equivalent to BC, meaning Before the Common Era or before the dawn of Christianity. Contrast this with CE, meaning Before Christ, or AD, a medieval Latin abbreviation. ADmeans “in the year of the Lord.” This dividing period (between BC and AD or between BC and AD, i.e., year 0) was the beginning of the Gregorian calendar. The Gregorian calendar began in the year early religious scholars believed Christ was born, and many scholars now write BC and AD because these terms eliminate any implicit association with religion.
Computer model: A program that runs on a computer and creates a model or simulation of a real-world feature, phenomenon, or event.
Egyptology: The study of Ancient Egypt from approximately 4500 BC to 641 AD, during the period of local kings known as the Pharaohs. Scholars began to investigate this culture around 1800, when Napoleon Bonaparte invaded Egypt. Much of this work is based on the discoveries of archaeologists. They have found documents that date back to around the time the first Pharaohs developed hieroglyphics (around 3150 BC). The dry climate of the region was well suited to preserving these documents and other aspects of early Egyptian culture.
engineer: someone who uses science and mathematics to solve problems. As a verb, engineer means to design a device, material, or process that solves some problem or unmet need.
Field: Field of study. Example: Her field of research is biology.It is also a term that describes the real-world environment in which some research takes place, such as the ocean, a forest, a mountaintop, or a city street, as opposed to an artificial environment such as a laboratory.
Freshwater: noun or adjective describing a body of water with a very low salt content, the kind of water used for drinking water and that makes up most inland lakes, ponds, rivers, streams, and groundwater.
granite: A type of hard igneous rock that contains coarse-grained inclusions (basically tiny rocks within rock) of a variety of minerals, mainly quartz, feldspar, and mica.
Hydraulic: (noun) Hydraulic) adjective referring to the movement of liquid under pressure in a pipe or other confined space. The science of using the movement of liquids to exert force or control is HydraulicThe equipment used to provide this type of control is also commonly known as hydraulic equipment.
conspiracy: (adjective) Interesting) To arouse curiosity or interest, or to plan or carry out something secretly.
Limestone: A natural rock formed by the accumulation of calcium carbonate over a long period of time and then being compressed under great pressure. Most sources of calcium carbonate come from the shells of dead marine animals. However, this chemical can also precipitate out of water, especially after the carbon dioxide has been removed (for example by plants).
Materials Science: The study of how a material's atomic and molecular structure relates to the material's overall properties. Materials scientists can design new materials or analyze existing materials. Analysis of a material's overall properties (such as density, strength, and melting point) helps engineers and other researchers select the best materials for new applications.
Model: A simulation (usually using a computer) of real-world events developed to predict one or more possible outcomes, or an individual intended to show how something might work or look in another environment.
network: A group of people or things related or connected to each other.
Physics: The scientific study of the nature and properties of matter and energy. Classical physics describes the nature and properties of matter and energy based on explanations such as Newton's laws of motion. Quantum physics, a later field of study, is a more precise way of describing the motion and behavior of matter. Scientists who work in these fields are called physicists.
pyramid: a monumental structure with a square or triangular base and sloping sides that meet at a point at the top. The best known are the royal tombs of Ancient Egypt, built of stone.
Spill: Rainwater runs off land into rivers, lakes and oceans. As the water passes through the soil, it picks up dirt and chemicals that are later deposited as pollutants in rivers, lakes and oceans.
system: A network of parts working together to accomplish some function. For example, blood, blood vessels, and the heart are the main components of the human body's circulatory system. Similarly, trains, platforms, tracks, road signals, and overpasses are some of the potential components of a country's rail system. System can also apply to a process or idea that is part of some method or ordered series of steps to complete a task.
