Brachiosaurus: With very lengthy necks and brief tails, these huge dinosaurs have been likened to large giraffes. Not like most dinos, their entrance legs have been longer than their hind limbs. Their physique form would have allowed these mammoth creatures to achieve their heads as a lot as 12 meters (39 ft) above the bottom — excessive sufficient to browse the leaves of tall bushes. Massive adults may have weighed practically 80 metric tons and reached a size of practically 25 meters (82 ft).
carbon: A chemical component that’s the bodily foundation of all life on Earth. Carbon exists freely as graphite and diamond. It is a crucial a part of coal, limestone and petroleum, and is able to self-bonding, chemically, to kind an unlimited variety of chemically, biologically and commercially essential molecules. (in local weather research) The time period carbon typically will probably be used virtually interchangeably with carbon dioxide to connote the potential impacts that some motion, product, coverage or course of might have on long-term atmospheric warming.
carbon fiber: Tiny fibers made from carbon atoms. Every fiber is between 5 to 10 micrometers thick (maybe a tenth of the width of a human hair). Sturdy and light-weight, carbon fibers can be utilized to bolster all the pieces from the blades of helicopters to protecting materials.
particles: Scattered fragments, usually of trash or of one thing that has been destroyed. House particles, as an illustration, consists of the wreckage of defunct satellites and spacecraft.
diffuse: adj.) To be unfold out thinly over a terrific space; not concise or concentrated. (v) To unfold gentle or to broadly launch some substance by means of a liquid (equivalent to water or air) or by means of some floor (equivalent to a membrane).
dinosaur: A time period meaning horrible lizard. These reptiles emerged round 243 million years in the past. All descended from egg-laying reptiles often called archosaurs. Their descendants ultimately break up into two strains. For a lot of many years, they’ve been distinguished by their hips. The lizard-hipped line are believed to have led to the saurischians, equivalent to two-footed theropods like T. rex and the lumbering four-footed Apatosaurus. A second line of so-called bird-hipped, or ornithischian dinosaurs, seems to have led to a broadly differing group of animals that included the stegosaurs and duckbilled dinosaurs. Many massive dinosaurs died out round 66 million years in the past. However some saurischians lived on. They’re now the birds we see as we speak (and who’ve now advanced that so-called “bird-hipped” pelvis).
dynamic: An adjective that signifies one thing is energetic, altering or shifting. (noun) The change or vary of variability seen or measured inside one thing.
engineer: An individual who makes use of science and math to unravel issues. As a verb, to engineer means to design a tool, materials or course of that can remedy some drawback or unmet want.
engineering: The sector of analysis that makes use of math and science to unravel sensible issues. Somebody who works on this discipline is named an engineer.
fiber: One thing whose form resembles a thread or filament. (in diet) Parts of many fibrous plant-based meals. These so-called non-digestible fibers have a tendency to return from cellulose, lignin, and pectin — all plant constituents that resist breakdown by the physique’s digestive enzymes.
fiberglass: A cloth made from glass strands.
filament: One thing with a skinny, thread-like form. For example, the delicate metallic wire that heats as much as emit gentle inside an incandescent gentle bulb is named its filament.
drive: Some outdoors affect that may change the movement of an object, maintain objects shut to at least one one other, or produce movement or stress in a stationary object.
fuse: (v.) To merge two issues collectively, typically alongside some seam. (n.) Some twine, tube or different materials that may burn and ultimately ignite an explosive. Or {an electrical} system that breaks {an electrical} circuit when it overheats, thus stopping electrical wires from getting sizzling sufficient to trigger a fireplace.
gravity: The drive that draws something with mass, or bulk, towards every other factor with mass. The extra mass that one thing has, the larger its gravity.
habitat: The realm or pure atmosphere through which an animal or plant usually lives, equivalent to a desert, coral reef or freshwater lake. A habitat might be residence to hundreds of various species.
hovercraft: A car that travels over land or water atop a river of air. Blowers ship a big jet of air beneath the car that’s barely above atmospheric strain. The strain distinction this air and decrease strain air above it creates elevate. That, in flip, permits the craft to drift atop a cushion of air.
laser: A tool that generates an intense beam of coherent gentle of a single coloration. Lasers are utilized in drilling and chopping, alignment and steering, in information storage and in surgical procedure.
mechanical: Having to do with the units that transfer, together with instruments, engines and different machines (even, doubtlessly, dwelling machines); or one thing attributable to the bodily motion of one other factor.
metallic: One thing that conducts electrical energy properly, tends to be shiny (reflective) and is malleable (that means it may be reshaped with warmth and never an excessive amount of drive or strain).
morph: Quick for metamorphose, it means to alter or remodel from one kind to a different (equivalent to from a caterpillar to a butterfly) or from one form to a different. Or it could possibly imply to evolve or mutate, the place a number of components of the genome endure some form of change of their chemistry — and doubtlessly of their operate. (in non-living techniques) It refers to some factor, coverage or exercise that has undergone change, turning into one thing that appears or appears new and completely different.
muscle: A sort of tissue used to supply motion by contracting its cells, often called muscle fibers. Muscle is wealthy in protein, which is why predatory species search prey containing a lot of this tissue.
orbit: The curved path of a celestial object or spacecraft round a galaxy, star, planet or moon. One full circuit round a celestial physique.
physics: The scientific examine of the character and properties of matter and vitality. Classical physics is an evidence of the character and properties of matter and vitality that depends on descriptions equivalent to Newton’s legal guidelines of movement. Quantum physics, a discipline of examine that emerged later, is a extra correct manner of explaining the motions and conduct of matter. A scientist who works in such areas is named a physicist.
robotic: A machine that may sense its atmosphere, course of info and reply with particular actions. Some robots can act with none human enter, whereas others are guided by a human.
roboticist: Somebody who designs or builds robots.
sauropod: A really massive, four-legged, plant-eating dinosaur with an extended neck and tail, small head and big limbs.
shock: (in biology and medication) A doubtlessly deadly bodily response to quite a lot of circumstances, together with sickness, damage, blood loss and lack of satisfactory water, normally characterised by marked lack of blood strain, decreased blood circulation and insufficient blood stream to the tissues.
sq.: (in geometry) A rectangle with 4 sides of equal size. (In arithmetic) A quantity multiplied by itself, or the verb that means to multiply a quantity by itself. The sq. of two is 4; the sq. of 10 is 100.
submarine: A time period for beneath the oceans. (in transportation) A ship designed to maneuver by means of the oceans, completely submerged. Such ships — particularly these utilized in analysis — are often known as submersibles.
floor space: The realm of some materials’s floor. Basically, smaller supplies and ones with rougher or extra convoluted surfaces have a larger exterior floor space — per unit mass — than bigger objects or ones with smoother exteriors. That turns into essential when chemical, organic or bodily processes happen on a floor.
expertise: The appliance of scientific information for sensible functions, particularly in trade — or the units, processes and techniques that outcome from these efforts.
tendon: A tissue within the physique that connects muscle and bone.
