Red is my favorite color. You see it everywhere! I love laser pointers because they're almost always red.
Red is the colour at the end of the visible spectrum of light, next to orange and opposite violet.

Laser pointer
A laser pointer or laser pen is a small handheld device with a power source (usually a battery) and a laser diode emitting a very narrow coherent low-powered laser beam of visible light, intended to be used to highlight something of interest by illuminating it with a small bright spot of colored light. Power is restricted in most jurisdictions not to exceed 5 mW. The small width of the beam and low power of typical laser pointers make the beam itself invisible in a reasonably clean atmosphere, only showing a point of light when striking an opaque surface. Some higher-powered laser pointers project a visible beam via scattering from dust particles or water droplets along the beam path.
Laser safety
Laser safety is the safe design, use and implementation of lasers to minimize the risk of laser accidents, especially those involving eye injuries. Since even relatively small amounts of laser light can lead to permanent eye injuries, the sale and usage of lasers is typically subject to government regulations. Moderate and high-power lasers are potentially hazardous because they can burn the retina of the eye, or even the skin. To control the risk of injury, various specifications, for example 21 Code of Federal Regulations (CFR) Part 1040 in the US and IEC 60825 internationally, define "classes" of laser depending on their power and wavelength.
Lasers and aviation safety
Under certain conditions, laser light or other bright lights (spotlights, searchlights) directed at aircraft can be a hazard. The most likely scenario is when a bright visible laser light causes distraction or temporary flash blindness to a pilot, during a critical phase of flight such as landing or takeoff. It is far less likely, though still possible, that a visible or invisible beam could cause permanent harm to a pilot's eyes. Although laser weapons are under development by the military, these are so specialized, expensive and controlled that it is improbable for non-military lasers to cause structural damage to an aircraft.
Laser
A laser is a device that emits light through a process of optical amplification based on the stimulated emission of electromagnetic radiation. The term "laser" originated as an acronym for "light amplification by stimulated emission of radiation". The first laser was built in 1960 by Theodore H. Maiman at Hughes Research Laboratories, based on theoretical work by Charles Hard Townes and Arthur Leonard Schawlow. A laser differs from other sources of light in that it emits light "coherently", spatially and temporally. Spatial coherence allows a laser to be focused to a tight spot, enabling applications such as laser cutting and lithography.
Red
Red is the colour at the end of the visible spectrum of light, next to orange and opposite violet. It has a dominant wavelength of approximately 625–740 nanometres. It is a primary color in the RGB color model and the CMYK color model, and is the complementary color of cyan. Reds range from the brilliant yellow-tinged scarlet and vermillion to bluish-red crimson, and vary in shade from the pale red pink to the dark red burgundy. The red sky at sunset results from Rayleigh scattering, while the red color of the Grand Canyon and other geological features is caused by hematite or red ochre, both forms of iron oxide.
Laser diode
A laser diode, (LD), injection laser diode (ILD), or diode laser is a semiconductor device similar to a light-emitting diode in which the laser beam is created at the diode's junction. Laser diodes are the most common type of lasers produced, with a wide range of uses that include fiber optic communications, barcode readers, laser pointers, CD/DVD/Blu-ray disc reading/recording, laser printing, laser scanning and light beam illumination. A laser diode is electrically a PIN diode. The active region of the laser diode is in the intrinsic (I) region, and the carriers (electrons and holes) are pumped into that region from the N and P regions respectively.
Pink
Pink is a pale red color that is named after a flower of the same name. It was first used as a color name in the late 17th century. According to surveys in Europe and the United States, pink is the color most often associated with charm, politeness, sensitivity, tenderness, sweetness, childhood, femininity and the romantic. It is associated with chastity and innocence when combined with white, but associated with eroticism and seduction when combined with purple or black. The color pink is named after the flowers, pinks, flowering plants in the genus "Dianthus," and derives from the frilled edge of the flowers.

That's...true. Don't think they had many laser pointers back then though. I'm excited that we may be going to Mars, the red planet, soon!
Iron oxide also gives the red color to the planet Mars.

List of The King of Braves GaoGaiGar characters
This is an index of characters and mecha in the anime and manga "The King of Braves GaoGaiGar" and "The King of Braves GaoGaiGar FINAL". A brave man with tremendous courage and enthusiasm, and the strength to never give up for the sake of life—even at the possible cost of his own. Former astronaut and test pilot for the Space Development Corporation. In 2003, he had been in orbit testing an experimental space shuttle when an extraterrestrial object (later classified as EI-01) suddenly appeared in his flight path, smashing his shuttle out of the way. This left the shuttle disabled and Guy himself in a near-death state.

ABC Warriors
ABC Warriors is a feature in the UK comic-book series "2000 AD" written by Pat Mills. It first appeared in program (issue) 119 in 1979 and continues to run as of 2018. Art for the opening episodes was by Kevin O'Neill, Mike McMahon, Brett Ewins, and Brendan McCarthy, who among them designed the original seven members of the team. Since then they have been illustrated primarily, though not exclusively, by Bryan Talbot, Simon Bisley, SMS, Kevin Walker, Henry Flint and Clint Langley. The A.B.C. Warriors are a team of war robots designed to withstand 'Atomic', 'Bacterial' and 'Chemical' warfare. They were built to take part in the long-running Volgan War, which Mills had described in several previous "2000 AD" strips, including "Invasion!"
Exploration of Mars
The exploration of Mars is the study of Mars by spacecraft. Probes sent from Earth, beginning in the late 20th century, have yielded a dramatic increase in knowledge about the Martian system, focused primarily on understanding its geology and habitability potential. Engineering interplanetary journeys is complicated and the exploration of Mars has experienced a high failure rate, especially the early attempts. Roughly two-thirds of all spacecraft destined for Mars failed before completing their missions and some failed before their observations could begin. Some missions have met with unexpected success, such as the twin Mars Exploration Rovers, which operated for years beyond their specification.

Mars Exploration Rover
NASA's Mars Exploration Rover (MER) mission is an ongoing robotic space mission involving two Mars rovers, Spirit and Opportunity, exploring the planet Mars. It began in 2003 with the launch of the two rovers: MER-A "Spirit" and MER-B "Opportunity"—to explore the Martian surface and geology; both landed on Mars at separate locations in January 2004. Both rovers far outlived their planned missions of 90 Martian solar days: MER-A "Spirit" was active until 2010, while MER-B "Opportunity" is still active in 2018, and holds the record for the longest distance driven by any off-Earth wheeled vehicle.

Water on Mars
Almost all water on Mars today exists as ice, though it also exists in small quantities as vapor in the atmosphere and occasionally as low-volume liquid brines in shallow Martian soil. The only place where water ice is visible at the surface is at the north polar ice cap. Abundant water ice is also present beneath the permanent carbon dioxide ice cap at the Martian south pole and in the shallow subsurface at more temperate certain conditions. More than five million cubic kilometers of ice have been identified at or near the surface of modern Mars, enough to cover the whole planet to a depth of .
Spirit (rover)
Spirit, also known as MER-A (Mars Exploration Rover – A) or MER-2, was a robotic rover on Mars, active from 2004 to 2010. It was one of two rovers of NASA's ongoing Mars Exploration Rover Mission. It landed successfully on Mars at 04:35 Ground UTC on January 4, 2004, three weeks before its twin, "Opportunity" (MER-B), landed on the other side of the planet. Its name was chosen through a NASA-sponsored student essay competition. The rover became stuck in late 2009, and its last communication with Earth was sent on March 22, 2010. The rover completed its planned 90-sol mission. Aided by cleaning events that resulted in more energy from its solar panels, "Spirit" went on to function effectively over twenty times longer than NASA planners expected.
Curiosity (rover)
Curiosity is a car-sized rover designed to explore Gale Crater on Mars as part of NASA's Mars Science Laboratory mission (MSL). "Curiosity" was launched from Cape Canaveral on November 26, 2011, at 15:02 UTC aboard the MSL spacecraft and landed on Aeolis Palus in Gale Crater on Mars on August 6, 2012, 05:17 UTC. The Bradbury Landing site was less than from the center of the rover's touchdown target after a journey. The rover's goals include an investigation of the Martian climate and geology; assessment of whether the selected field site inside Gale Crater has ever offered environmental conditions favorable for microbial life, including investigation of the role of water; and planetary habitability studies in preparation for human exploration.
Composition of Mars
The composition of Mars covers the branch of the geology of Mars that describes the make-up of the planet Mars. Also like Earth, Mars is a differentiated planet, meaning that it has a central core made up of metallic iron and nickel surrounded by a less dense, silicate mantle and crust. The planet's distinctive red colour is due to the oxidation of iron on its surface. Much of what we know about the elemental composition of Mars comes from orbiting spacecraft and landers. (See Exploration of Mars for list.) Most of these spacecraft carry spectrometers and other instruments to measure the surface composition of Mars by either remote sensing from orbit or "in situ" analyses on the surface.
Mars Science Laboratory
Mars Science Laboratory (MSL) is a robotic space probe mission to Mars launched by NASA on November 26, 2011, which successfully landed "Curiosity", a Mars rover, in Gale Crater on August 6, 2012. The overall objectives include investigating Mars' habitability, studying its climate and geology, and collecting data for a manned mission to Mars. The rover carries a variety of scientific instruments designed by an international team. MSL successfully carried out the most accurate Martian landing of any known spacecraft, hitting a small target landing ellipse of only , in the Aeolis Palus region of Gale Crater.

Cool. I feel like I could smash some stoneware pottery right now out of frustration, to be honest.
Pottery is the ceramic material which makes up potterywares, of which major types include earthenware, stoneware and porcelain.

Langley Mill Pottery
Langley Mill Pottery was located in Langley Mill, Derbyshire on the Derbyshire – Nottinghamshire border. From its establishment in 1865 to its final closure in 1982, the pottery went through five distinct periods of ownership, producing a wide range of stoneware ranging from salt glazed ink bottles, utilitarian items and tableware to high quality and original art pottery. In 1865, James Calvert, a chemist and druggist from Belper, Derbyshire, established the Langley Mill pottery on the site of a former brick-works. The company was known at that time as James Calvert. Historically, this area was already one of the major producers of stoneware pottery due to its location over the Derbyshire – Nottinghamshire Coal Field and several other stoneware potteries were already operational at that time.
Mexican ceramics
Ceramics in Mexico date back thousands of years before the Pre-Columbian period, when ceramic arts and pottery crafts developed with the first advanced civilizations and cultures of Mesoamerica. With one exception, pre-Hispanic wares were not glazed, but rather burnished and painted with colored fine clay slips. The potter's wheel was unknown as well; pieces were shaped by molding, coiling and other methods. After the Spanish Invasion and Conquest, European techniques and designs were introduced, nearly wiping out the native traditions. Indigenous traditions survive in a few pottery items such as comals, and the addition of indigenous design elements into mostly European motifs.
American stoneware
American Stoneware is a type of stoneware pottery popular in 19th century North America. The predominant houseware of the era, it was usually covered in a salt glaze and often decorated using cobalt oxide to produce bright blue decorations. The vernacular term "crocks" is often used to describe this type of pottery, though the term "crock" is not seen in period documents describing the ware. Additionally, while other types of stoneware were produced in America concurrently with it—for instance, ironstone, yellowware, and various types of china—in common usage the term "American Stoneware" refers to this specific type of pottery.
Korean influence on Japanese culture
Korean influence on Japanese culture refers to the impact of continental Asian influences transmitted through or originating in the Korean Peninsula on Japanese institutions, culture, language and society. Since the Korean Peninsula was the cultural bridge between Japan and the Asian continent throughout much of Far Eastern history, these influences have been detected in a variety of aspects of Japanese culture, including technology, philosophy, art, and artistic techniques. Notable examples of Korean influence on Japanese culture include the prehistoric migration of Korean peninsular peoples to Japan near the end of Japan's Jōmon period and the introduction of Buddhism to Japan via the Kingdom of Baekje in 538 AD.
Michael Cardew
Michael Ambrose Cardew, CBE (1901–1983), was an English studio potter who worked in West Africa for twenty years. Cardew was born in Wimbledon, London, the fourth child of Arthur Cardew, a civil servant, and Alexandra Kitchin, the eldest daughter of G.W.Kitchin, the first Chancellor of Durham University. His family had a holiday home in North Devon, where Arthur Cardew collected Devon country pottery. Cardew first saw this pottery being made in the workshop of Edwin Beer Fishley at Braunton and learned to make pottery on the wheel from Fishley's grandson, William Fishley Holland. He gained a scholarship to read Classics at Exeter College, Oxford.
Ceramic art
Ceramic art is art made from ceramic materials, including clay. It may take forms including art ware, tile, figurines, sculpture, and tableware. Ceramic art is one of the arts, particularly the visual arts. Of these, it is one of the plastic arts. While some ceramics are considered fine art, as pottery or sculpture, some are considered to be decorative, industrial or applied art objects. Ceramics may also be considered artefacts in archaeology. Ceramic art can be made by one person or by a group of people. In a pottery or ceramic factory, a group of people design, manufacture and decorate the art ware.
Chinese ceramics
Chinese ceramics show a continuous development since pre-dynastic times and are one of the most significant forms of Chinese art and ceramics globally. The first pottery was made during the Palaeolithic era. Chinese ceramics range from construction materials such as bricks and tiles, to hand-built pottery vessels fired in bonfires or kilns, to the sophisticated Chinese porcelain wares made for the imperial court and for export. Porcelain is so identified with China that it is still called "china" in everyday English usage. Most later Chinese ceramics, even of the finest quality, were made on an industrial scale, thus few names of individual potters were recorded.
