atom: (adj. atomic) The essential unit of a chemical component. Atoms are made up of a dense nucleus that comprises positively charged protons and uncharged neutrons. The nucleus is orbited by a cloud of negatively charged electrons.

atomic clock: A timekeeping gadget that depends on the frequency of microwave emissions from excited atoms. For instance, for the cesium atom that frequency is 9,192,631,770 hertz (or cycles/oscillations per second). Many frequent gadgets together with cell telephones, computer systems and GPS-satellite receivers depend on the excessive accuracy of atomic clocks to repeatedly reset their time (often known as synchronization).

autonomous: Appearing independently. Autonomous autos, as an example, pilot themselves based mostly on directions which have been programmed into their pc steering system.

habits: The way in which one thing, usually an individual or different organism, acts in direction of others, or conducts itself.

local weather change: Lengthy-term, vital change within the local weather of Earth. It will possibly occur naturally or in response to human actions, together with the burning of fossil fuels and clearing of forests.

cloud: A plume of molecules or particles, comparable to water droplets, that transfer below the motion of an outdoor power, comparable to wind, radiation or water currents. 

cosmology: The science of the origin and improvement of the cosmos, or universe. Individuals who work on this area are often known as cosmologists.

dilation: A time period that refers to widening of a gap (such because the pupil of an organism’s eye or the lens of a digital camera) or lengthening/stretching of one thing (comparable to time).

distort: (n. distortion) To alter the form or picture of one thing in a method that makes it exhausting to acknowledge, or to vary the notion or characterization of one thing (as to mislead).

electrical area: A area round a charged particle or object inside which a power can be exerted on different charged particles or objects.

electronics: Gadgets which might be powered by electrical energy however whose properties are managed by the semiconductors or different circuitry that channel or gate the motion of electrical prices.

elevation: The peak or altitude at which one thing exists.

power: Some outdoors affect that may change the movement of a physique, maintain our bodies shut to 1 one other, or produce movement or stress in a stationary physique.

frequency: The variety of occasions some periodic phenomenon happens inside a specified time interval. (In physics) The variety of wavelengths that happens over a specific interval of time.

basic: One thing that’s primary or serves as the muse for an additional factor or thought.

glacier: A slow-moving river of ice a whole lot or 1000’s of meters deep. Glaciers are present in mountain valleys and in addition type elements of ice sheets.

GPS: Abbreviation for world positioning system, which makes use of a tool to calculate the place of people or issues (by way of latitude, longitude and elevation — or altitude) from anyplace on the bottom or within the air. The gadget does this by evaluating how lengthy it takes alerts from totally different satellites to achieve it.

graduate pupil: Somebody working towards a sophisticated diploma by taking courses and performing analysis. This work is finished after the coed has already graduated from school (often with a four-year diploma).

gravity: The power that draws something with mass, or bulk, towards another factor with mass. The extra mass that one thing has, the larger its gravity.

laser: A tool that generates an intense beam of coherent mild of a single colour. Lasers are utilized in drilling and reducing, alignment and steering, in knowledge storage and in surgical procedure.

Nationwide Institute of Requirements and Know-how (NIST): A U.S. authorities analysis company based in 1901 because the Nationwide Bureau of Requirements. Its identify modified to NIST in 1988. Through the years, NIST has grow to be a serious heart for analysis within the bodily sciences. Certainly one of its enduring capabilities is the event of latest and extra exact methods to measure issues, from time and electrical energy to the scale of an atom and wavelengths of sunshine. With services in Gaithersburg, Md., and Boulder, Colo., it employs some 2,900 individuals.

optical: An adjective that refers to mild or imaginative and prescient.

oscillate: To swing forwards and backwards with a gentle, uninterrupted rhythm.

main: An adjective that means main, first or most necessary. (In reference to colours). The essential hues that may mix to make all different colours. For mixing mild, the first colours are purple, inexperienced, and blue.

quantum: (pl. quanta) A time period that refers back to the smallest quantity of something, particularly of vitality or subatomic mass.

quantum physics: A department of physics that makes use of quantum concept to clarify or predict how a bodily system will function on the dimensions of atoms or sub-atomic particles.

regime: A system of presidency or a longtime group that tends to ascertain guidelines; or the conventional or typical method of taking a look at one thing or doing one thing.

relativity: (in physics) A concept developed by physicist Albert Einstein displaying that neither area nor time are fixed, however as an alternative affected by one’s velocity and the mass of issues in your neighborhood.

system: A community of elements that collectively work to realize some operate. For example, the blood, vessels and coronary heart are main parts of the human physique’s circulatory system. Equally, trains, platforms, tracks, roadway alerts and overpasses are among the many potential parts of a nation’s railway system. System may even be utilized to the processes or concepts which might be a part of some technique or ordered set of procedures for getting a job completed.

know-how: The applying of scientific information for sensible functions, particularly in business — or the gadgets, processes and techniques that end result from these efforts.

concept: (in science) An outline of some facet of the pure world based mostly on in depth observations, checks and purpose. A concept will also be a method of organizing a broad physique of information that applies in a broad vary of circumstances to clarify what is going to occur. In contrast to the frequent definition of concept, a concept in science is not only a hunch. Concepts or conclusions which might be based mostly on a concept — and never but on agency knowledge or observations — are known as theoretical. Scientists who use arithmetic and/or present knowledge to mission what would possibly occur in new conditions are often known as theorists.

trillion: A quantity representing one million million — or 1,000,000,000,000 — of one thing.

universe: The complete cosmos: All issues that exist all through area and time. It has been increasing since its formation throughout an occasion often known as the Large Bang, some 13.8 billion years in the past (give or take a number of hundred million years).

vacuum: Area with little or irrespective of in it. Laboratories or manufacturing crops could use vacuum gear to pump out air, creating an space often known as a vacuum chamber.
