Remote sensing

In the broadest sense, remote sensing is the extent or acquisition of information of an object or phenomenon, by a recording device that is not in physical or intimate contact with the object. In practice, remote sensing is the operation at a distance (as from aircraft, spacecraft, satellite, or ship) of any device for gathering information about the environment. Thus an aircraft taking photographs, Earth examination and weather satellites, monitoring of a pregnancy via ultrasound, and space probes are all examples of remote sensing. In modern usage, the term usually refers to techniques involving the use of instruments aboard aircraft and spacecraft, and is distinct from other imaging-related fields such as medical imaging or photogrammetry.

With remote sensing we can study unsafe or difficult to reach regions. A hazardous area might be a wildfire site, or a hurricane. Using remote sensing we can better understand water patterns of the whole Amazon region. We can take measurements from polar regions and oceans' depths. Taking measurements remotely also ensures that we won't disturb the object being studied.

Virtual Reality

Virtual reality (VR) is a technology which allows a user to work together with a computer-simulated environment, be it a real or imagined one. Most current virtual reality environments are mostly visual experiences, displayed either on a computer screen or through special stereoscopic displays, but some simulations include additional sensory information, such as sound through speakers or headphones. Some superior, haptic systems now include tactile information, generally known as force feedback, in medical and gaming applications. Users can act together with a virtual environment or a virtual artifact (VA) either through the use of standard input devices such as a keyboard and mouse, or through multimodal devices such as a wired glove, the Polhemus boom arm, and omnidirectional treadmill. The simulated environment can be similar to the real world, for example, simulations for pilot or combat training, or it can differ significantly from reality, as in VR games. In practice, it is currently very difficult to create a high-fidelity virtual reality experience, due mostly to technical limitations on processing power, image resolution and communication bandwidth. However, those limitations are expected to eventually be overcome as processor, imaging and data communication technologies become more powerful and cost-effective over time.

Graphic novel

A graphic novel is a long-form work in the comics form, regularly with lengthy and complex storylines, and often aimed at mature audiences. In contrast to the familiar comic magazines, a graphic novel is typically bounce using materials of more durable qualities, using a light card stock for soft cover bindings or a heavier card for the hardback editions, enclosed in a dirt jacket. Graphic novels generally are sold in bookstores and comic book shops, rather than on comic books' original point of sale, newsstands.
The term can also include a short story collection, or collected issues of previously published comic books republished in a single large volume.Comic works formed and published as a single narrative, without prior look in magazines, comic books or newspapers are called original graphic novels.The evolving term "graphic novel" is not firmly defined, and is sometimes used, controversially, to imply subjective distinctions in artistic quality between graphic novels and other kinds of comics. It is frequently used to disassociate works from the juvenile or humorous connotations of the terms "comics" and "comic book", implying that the work is more serious, mature, or literary than traditional comics.
