accelerator: (in physics) Also called a particle accelerator, this huge machine revs up the movement of subatomic particles to nice pace, after which beams them at targets. Typically the beams are used to ship radiation at a tissue for most cancers therapy. Different occasions, scientists crash the particles into strong targets in hopes of breaking the particles into their constructing blocks.
calorie: The quantity of power wanted to boost the temperature of 1 gram of water by 1 diploma Celsius. It’s usually used as a measurement of the power contained in some outlined quantity of meals. The exception: when referring to the power in meals, the conference is to name a kilocalorie, or 1,000 of those energy, a “calorie.” Right here, a meals calorie is the quantity of power wanted to boost 1 kilogram of water 1 diploma C.
chemical: A substance fashioned from two or extra atoms that unite (bond) in a hard and fast proportion and construction. For instance, water is a chemical made when two hydrogen atoms bond to 1 oxygen atom. Its chemical components is H2O. Chemical additionally might be an adjective to explain properties of supplies which are the results of numerous reactions between totally different compounds.
chemical engineer: A researcher who makes use of chemistry to unravel issues associated to the manufacturing of meals, gasoline, medicines and lots of different merchandise.
chemistry: The sector of science that offers with the composition, construction and properties of drugs and the way they work together. Scientists use this data to review unfamiliar substances, to breed massive portions of helpful substances or to design and create new and helpful substances. (about compounds) Chemistry is also used as a time period to confer with the recipe of a compound, the way in which it’s produced or a few of its properties. Individuals who work on this subject are often called chemists. (in social science) A time period for the flexibility of individuals to cooperate, get alongside and revel in one another’s firm.
coil: Concentric rings or spirals fashioned by winding wire or another fiber round and round a core; or the form that such a wire would make.
crystal: (adj. crystalline) A strong consisting of a symmetrical, ordered, three-dimensional association of atoms or molecules. It’s the organized construction taken by most minerals. Apatite, for instance, varieties six-sided crystals. The mineral crystals that make up rock are often too small to be seen with the unaided eye.
develop: To emerge or to make come into being, both naturally or by means of human intervention, corresponding to by manufacturing. (in biology) To develop as an organism from conception by means of maturity, typically present process modifications in chemistry, measurement, psychological maturity or typically even form.
dimension: Descriptive options of one thing that may be measured, corresponding to size, width or time.
engineer: An individual who makes use of science to unravel issues. As a verb, to engineer means to design a tool, materials or course of that can clear up some drawback or unmet want. (v.) To carry out these duties, or the identify for an individual who performs such duties.
filter: (n.) One thing that enables some supplies to cross by means of however not others, primarily based on their measurement or another function. (v.) The method of screening some issues out on the idea of traits corresponding to measurement, density, electrical cost. (in physics) A display screen, plate or layer of a substance that absorbs gentle or different radiation or selectively prevents the transmission of a few of its parts.
flask: A kind of container with a slender neck. Within the laboratory, sterile flasks constructed from glass are used for conducting chemical and organic experiments.
glass: A tough, brittle substance constructed from silica, a mineral present in sand. Glass often is clear and pretty inert (chemically nonreactive). Aquatic organisms referred to as diatoms construct their shells of it.
impermeable: An adjective for one thing that won’t let a liquid stream by means of it.
inert: Inactive or having no chemical or bodily results.
laser: A tool that generates an intense beam of coherent gentle of a single colour. Lasers are utilized in drilling and slicing, alignment and steering, in knowledge storage and in surgical procedure.
matter: One thing that occupies area and has mass. Something on Earth with matter can have a property described as “weight.”
molten: A phrase describing one thing that’s melted, such because the liquid rock that makes up lava.
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 middle for analysis within the bodily sciences. One in all its enduring capabilities is the event of recent and extra exact methods to measure issues, from time and electrical energy to the scale of an atom and wavelengths of sunshine. With amenities in Gaithersburg, Md., and Boulder, Colo., it employs some 2,900 folks.
optical: An adjective that refers to gentle or imaginative and prescient.
organ: (in biology) Numerous elements of an organism that carry out a number of explicit capabilities. As an illustration, an ovary is an organ that makes eggs, the mind is an organ that is sensible of nerve alerts and a plant’s roots are organs that soak up vitamins and moisture.
particle: A minute quantity of one thing.
patent: A authorized doc that offers inventors management over how their innovations — together with units, machines, supplies, processes and substances — are made, used and offered for a set time period. Presently in the USA, this runs 20 years from the date you first file for the patent. The U.S. authorities solely grants patents to innovations proven to be distinctive.
physicist: A scientist who research the character and properties of matter and power.
recall: To recollect.
pace of sunshine: A relentless typically utilized in physics, akin to 1.08 billion kilometers (671 million miles) per hour.
requirements: (in analysis) The values or supplies used as benchmarks towards which different issues might be in contrast. As an illustration, clocks try to match the official customary benchmark of time — the second, as calculated by the official atomic clock. Equally, scientists look to determine a chemical by matching its properties towards a recognized customary for a selected chemical.
subatomic: Something smaller than an atom, which is the smallest little bit of matter that has all of the properties of no matter chemical component it’s (like hydrogen, iron or calcium).
synchrotron: A round particle accelerator that hastens charged particles to just about the pace of sunshine, by making use of magnetic and electrical fields that ramp up their energy in synchrony. It additionally depends on a mixture of various kinds of magnets to maintain the beam of particles circulating and targeted.
expertise: The applying of scientific data for sensible functions, particularly in trade — or the units, processes and techniques that consequence from these efforts.
telescope: Normally a light-collecting instrument that makes distant objects seem nearer by means of using lenses or a mixture of curved mirrors and lenses. Some, nevertheless, accumulate radio emissions (power from a unique portion of the electromagnetic spectrum) by means of a community of antennas.
trait: A attribute function of one thing. (in genetics) A high quality or attribute that may be inherited.
distinctive: One thing that’s not like anything; the one one in every of its form.
universe: The complete cosmos: All issues that exist all through area and time. It has been increasing since its formation throughout an occasion often called the Huge Bang, some 13.8 billion years in the past (give or take just a few hundred million years).
X-ray: A kind of radiation analogous to gamma rays, however having considerably decrease power.
