❤️ Hellbender 🐞

"The hellbender (Cryptobranchus alleganiensis), also known as the hellbender salamander, is a species of aquatic giant salamander endemic to the eastern and central United States. A member of the family Cryptobranchidae, the hellbender is the only extant member of the genus Cryptobranchus. Other closely related salamanders in the same family are in the genus Andrias, which contains the Japanese and Chinese giant salamanders. The hellbender, which is much larger than all other salamanders in its geographic range, employs an unusual means of respiration (which involves cutaneous gas exchange through capillaries found in its dorsoventral skin folds), and fills a particular niche—both as a predator and prey—in its ecosystem, which either it or its ancestors have occupied for around 65 million years. The species is listed as Near Threatened on the IUCN Red List of Threatened Species. Etymology The origin of the name "hellbender" is unclear. The Missouri Department of Conservation says: > The name 'hellbender' probably comes from the animal's odd look. One theory > claims the hellbender was named by settlers who thought "it was a creature > from hell where it's bent on returning." Another rendition says the > undulating skin of a hellbender reminded observers of "horrible tortures of > the infernal regions." In reality, it's a harmless aquatic salamander. Other vernacular names include snot otter, lasagna lizard, devil dog, mud- devil, grampus, Allegheny alligator, mud dog, water dog, spotted water gecko and leverian water newt. The genus name is derived from the Ancient Greek kryptos (hidden) and branchion (gill). The subspecific name bishopi is in honor of American herpetologist Sherman C. Bishop. Description C. alleganiensis has a flat body and head, with beady dorsal eyes and slimy skin. Like most salamanders, it has short legs with four toes on the front legs and five on its back limbs, and its tail is keeled for propulsion. The hellbender has working lungs, but gill slits are often retained, although only immature specimens have true gills; the hellbender absorbs oxygen from the water through capillaries of its side frills. It is blotchy brown or red-brown in color, with a paler underbelly. Both males and females grow to an adult length of from snout to vent, with a total length of , making them the third-largest aquatic salamander species in the world (after the Chinese giant salamander and the Japanese giant salamander, respectively) and the largest amphibian in North America, although this length is rivaled by the reticulated siren of the southeastern United States (although the siren is much leaner in build). An adult weighs , making them the fourth heaviest living amphibian in the world after their Chinese and Japanese cousins and the goliath frog, while the largest cane toads may also weigh as much as a hellbender. Hellbenders reach sexual maturity at about five years of age, and may live 30 years in captivity.Mayasich, J.; Grandmaison, D.; Phillips, C. (June 2003) Eastern Hellbender Status Assessment Report The hellbender has a few characteristics that make it distinguishable from other native salamanders, including a gigantic, dorsoventrally flattened body with thick folds travelling down the sides, a single open gill slit on each side, and hind feet with five toes each. Easily distinguished from most other endemic salamander species simply by their size, hellbenders average up to 60 cm or about 2 ft in length; the only species requiring further distinction (due to an overlap in distribution and size range) is the common mudpuppy (Necturus maculosus).Cryptobranchus alleganiensis AmphibiaWeb: Information on amphibian biology and conservation. [web application]. 2012. Berkeley, California: AmphibiaWeb. Available: http://amphibiaweb.org/. (Accessed: 15 November 2012). This demarcation can be made by noting the presence of external gills in the mudpuppy, which are lacking in the hellbender, as well as the presence of four toes on each hind foot of the mudpuppy (in contrast with the hellbender's five). Furthermore, the average size of C. a. alleganiensis has been reported to be 45–60 cm (with some reported as reaching up to 74 cm or 30 in), while N. m. maculosus has a reported average size of 28–40 cm in length, which means that hellbender adults will still generally be notably larger than even the biggest mudpuppies. Taxonomy The genus Cryptobranchus has historically only been considered to contain one species, C. alleganiensis, with two subspecies, C. a. alleganiensis and C. a. bishopi. A recent decline in population size of the Ozark subspecies C. a. bishopi has led to further research into populations of this subspecies, including genetic analysis to determine the best method for conservation. Crowhurst et al., for instance, found that the "Ozark subspecies" denomination is insufficient for describing genetic (and therefore evolutionary) divergence within the genus Cryptobranchus in the Ozark region. They found three equally divergent genetic units within the genus: C. a. alleganiensis, and two distinct eastern and western populations of C. a. bishopi. These three groups were shown to be isolated, and are considered to most likely be "diverging on different evolutionary paths". Distribution Hellbenders are present in a number of Eastern US states, from southern New York to northern Georgia, including parts of Ohio, Pennsylvania, Maryland, West Virginia, Virginia, Kentucky, Illinois, Indiana, Tennessee, North Carolina, South Carolina, Alabama, Mississippi, Arkansas, Missouri, and even a small bit of Oklahoma and Kansas. The subspecies (or species, depending on the source) C. a. bishopi is confined to the Ozarks of northern Arkansas and southern Missouri, while C. a. alleganiensis is found in the rest of these states. Some hellbender populations—namely a few in Missouri, Pennsylvania, and Tennessee—have historically been noted to be quite abundant, but several man-made maladies have converged on the species such that it has seen a serious population decline throughout its range. Hellbender populations were listed in 1981 as already extinct or endangered in Illinois, Indiana, Iowa, and Maryland, decreasing in Arkansas and Kentucky, and generally threatened as a species throughout their range by various human activities and developments. Ecology The hellbender salamander, considered a "habitat specialist", has adapted to fill a specific niche within a very specific environment, and is labeled as such "because its success is dependent on a constancy of dissolved oxygen, temperature and flow found in swift water areas", which in turn limits it to a narrow spectrum of stream/river choices. As a result of this specialization, hellbenders are generally found in areas with large, irregularly shaped, and intermittent rocks and swiftly moving water, while they tend to avoid wider, slow-moving waters with muddy banks and/or slab rock bottoms. This specialization likely contributed to the decline in their populations, as collectors could easily identify their specific habitats. One collector noted, at one time, "one could find a specimen under almost every suitable rock", but after years of collecting, the population had declined significantly. The same collector noted, he "never found two specimens under the same rock", corroborating the account given by other researchers that hellbenders are generally solitary; they are thought to gather only during the mating season. Both subspecies, C. a. alleganiensis and C. a. bishopi undergo a metamorphosis after around a year and a half of life. At this point, when they are roughly 13.5 cm long, they lose the gills present during their larval stage. Until then, they are easily confused with mudpuppies, and can be differentiated often only through toe number. After this metamorphosis, hellbenders must be able to absorb oxygen through the folds in their skin, which is largely behind the need for fast-moving, oxygenated water. If a hellbender ends up in an area of slow-moving water, not enough of it will pass over its skin in a given time, making it difficult to garner enough oxygen to support necessary respiratory functions. A below-favorable oxygen content can make life equally difficult. Hellbenders are preyed upon by diverse predators, including various fish and reptiles (including both snakes and turtles). Cannibalism of eggs is also considered a common occurrence. Life history and behavior=Behavior Once a hellbender finds a favorable location, it generally does not stray too far from it—except occasionally for breeding and hunting—and will protect it from other hellbenders both in and out of the breeding season. While the range of two hellbenders may overlap, they are noted as rarely being present in the overlapping area when the other salamander is in the area. The species is at least somewhat nocturnal, with peak activity being reported by one source as occurring around "two hours after dark" and again at dawn (although the dawn peak was recorded in the lab and could be misleading as a result). Nocturnal activity has been found to be most prevalent in early summer, perhaps coinciding with highest water depths. Diet C. alleganiensis feeds primarily on crayfish and small fish. One report, written by a commercial collector in the 1940s, noted a trend of more crayfish predation in the summer during times of higher prey activity, whereas fish made up a larger part of the winter diet, when crayfish are less active. There seems to be a specific temperature range in which hellbenders feed, as well: between 45 and 80 °F. Cannibalism—mainly on eggs—has been known to occur within hellbender populations. One researcher claimed perhaps density is maintained, and density dependence in turn created, in part by intraspecific predation. Reproduction The hellbenders' breeding season begins in late August or early- to mid-September and can continue as late as the end of November, depending on region. They exhibit no sexual dimorphism, except during the fall mating season, when males have a bulging ring around their cloacal glands. Unlike most salamanders, the hellbender performs external fertilization. Before mating, each male excavates a brood site, a saucer- shaped depression under a rock or log, with its entrance positioned out of the direct current, usually pointing downstream. The male remains in the brood site awaiting a female. When a female approaches, the male guides or drives her into his burrow and prevents her from leaving until she oviposits. Female hellbenders lay 150–200 eggs over a two- to three-day period; the eggs are 18–20 mm in diameter, connected by five to 10 cords. As the female lays eggs, the male positions himself alongside or slightly above them, spraying the eggs with sperm while swaying his tail and moving his hind limbs, which disperses the sperm uniformly. The male often tempts other females to lay eggs in his nest, and as many as 1,946 eggs have been counted in a single nest. Cannibalism, however, leads to a much lower number of eggs in hellbender nests than would be predicted by egg counts. After oviposition, the male drives the female away from the nest and guards the eggs. Incubating males rock back and forth and undulate their lateral skin folds, which circulates the water, increasing oxygen supply to both eggs and adult. Incubation lasts from 45 to 75 days, depending on region. Hatchling hellbenders are 25–33 mm long, have a yolk sac as a source of energy for the first few months of life, and lack functional limbs. Adaptations Hellbenders are superbly adapted to the shallow, fast-flowing, rocky streams in which they live. Their flattened shape offers little resistance to the flowing water, allowing them to work their way upstream and also to crawl into narrow spaces under rocks. Although their eyesight is relatively poor, they have light-sensitive cells all over their bodies. Those on their tails are especially finely tuned and may help them position safely under rocks without their tails poking out to give themselves away. They have a good sense of smell and move upstream in search of food such as dead fish, following the trail of scent molecules. Smell is possibly their most important sense when hunting. They also have a lateral line similar to those of fish, with which they can detect vibrations in the water. Hellbender on display at the Smithsonian National Zoological Park, Washington, DC Conservation status Research throughout the range of the hellbender has shown a dramatic decline in populations in the majority of locations. Many different anthropogenic sources have helped to create this decline, including the siltation and sedimentation, blocking of dispersal/migration routes, and destruction of riverine habitats created by dams and other development, as well as pollution, disease and overharvesting for commercial and scientific purposes. As many of these detrimental effects have irreversibly damaged hellbender populations, it is important to conserve the remaining populations through protecting habitats and—perhaps in places where the species was once endemic and has been extirpated—by augmenting numbers through reintroduction. Due to sharp decreases seen in the Ozark subspecies, researchers have been trying to differentiate C. a. alleganiensis and C. a. bishopi into two management units. Indeed, researchers found significant genetic divergence between the two groups, as well as between them and another isolated population of C. a. alleganiensis. This could be reason enough to ensure work is done on both subspecies, as preserving extant genetic diversity is of crucial ecological importance. The Ozark hellbender has been listed as an endangered species under the Endangered Species Act by the US Fish and Wildlife Service since October 5, 2011. This hellbender subspecies inhabits the White River and Spring River systems in southern Missouri and northern Arkansas, and its population has declined an estimated 75% since the 1980s, with only about 590 individuals remaining in the wild. Degraded water quality, habitat loss resulting from impoundments, ore and gravel mining, sedimentation, and collection for the pet trade are thought to be the main factors resulting in the amphibian's decline. When chytridiomycosis killed 75% of the St. Louis Zoo's captive hellbender population between March 2006 and April 2007, tests began to be conducted on wild populations. The disease has been detected in all Missouri populations of the Ozark hellbender. The Ozark hellbender was successfully bred in captivity for the first time at the St. Louis Zoo, in a joint project with the Missouri Department of Conservation, hatching on November 15, 2011. Apart from the Ozark efforts, head-starting programs, in which eggs are collected from the wild and raised in captivity for re-release at a less vulnerable stage, have been initiated in New York and Ohio. Members of the Pennsylvania State Senate have voted to approve the eastern hellbender as the official state amphibian in an effort to raise awareness about its endangered status. The legislation has been mired in controversy due to a dispute by House members who argue that Wehrle's salamander should be given the honor.Frank Kummer, "Seriously? Battle Looms Over Pa Staet Amphibian: Hellbender vs. Wehrle's", Philadelphia Inquirer, November 16, 2017, http://www.philly.com/philly/health/hellbender-snot-otter- pennsylvanias-official-amphibian-20171116.html The legislation did not pass in 2018, but was reintroduced in 2019.B. J. Small, "The Hellbender is One Step Closer to Becoming the Official PA State Amphibian", York Daily Record, January 29, 2019. On April 23, 2019, Pennsylvania Governor Tom Wolf signed legislation making the eastern hellbender Pennsylvania's official state amphibian. Youth members of the Chesapeake Bay Foundation's Pennsylvania Student Leadership Council were heavily involved writing and advocating on behalf of this legislation. They hope that the success of the hellbender bill in the Pennsylvania Senate will contribute to clean water efforts and raise awareness for the hellbender's struggling population.

❤️ Harold Eugene Edgerton 🐞

"Harold Eugene "Doc" Edgerton, also known as Papa Flash (April 6, 1903 – January 4, 1990) was a professor of electrical engineering at the Massachusetts Institute of Technology. He is largely credited with transforming the stroboscope from an obscure laboratory instrument into a common device. He also was deeply involved with the development of sonar and deep-sea photography, and his equipment was used by Jacques Cousteau in searches for shipwrecks and even the Loch Ness Monster. Biography=Early years Edgerton was born in Fremont, Nebraska, on April 6, 1903, the son of Mary Nettie Coe and Frank Eugene Edgerton,Frank Eugene Edgerton/Mary Nettie Coe – rootsweb a descendant of Richard Edgerton, one of the founders of Norwich, Connecticut and a descendant of Governor William Bradford (1590–1657) of the Plymouth Colony and a passenger on the Mayflower. His father was a lawyer, journalist, author and orator and served as the assistant attorney general of Nebraska from 1911 to 1915. Edgerton grew up in Aurora, Nebraska. He also spent some of his childhood years in Washington, D.C., and Lincoln, Nebraska. Education A 1936 picture of May Rogers Webster with hummingbirds In 1925 Edgerton received a bachelor's degree in electrical engineering from the University of Nebraska-Lincoln where he became a member of Acacia fraternity. He earned an SM in electrical engineering from MIT in 1927. Edgerton used stroboscopes to study synchronous motors for his Sc.D. thesis in electrical engineering at MIT, awarded in 1931. He credited Charles Stark Draper with inspiring him to photograph everyday objects using electronic flash; the first was a stream of water from a faucet. In 1936 Edgerton visited hummingbird expert May Rogers Webster. He was able to illustrate with her help that it was possible to take photographs of the birds beating their wings 60 times a second using an exposure of one hundred thousandth of a second. A picture of her with the birds flying around her appeared in National Geographic. Career Nuclear explosion captured by Edgerton's Rapatronic camera Shadowgraph of bullet in flight using Edgerton's equipment and stroboscope In 1937 Edgerton began a lifelong association with photographer Gjon Mili, who used stroboscopic equipment, in particular, multiple studio electronic flash units, to produce strikingly beautiful photographs, many of which appeared in Life Magazine. When taking multiflash photographs this strobe light equipment could flash up to 120 times a second. Edgerton was a pioneer in using short duration electronic flash in photographing fast events photography, subsequently using the technique to capture images of balloons at different stages of their bursting, a bullet during its impact with an apple, or using multiflash to track the motion of a devil stick, for example. He was awarded a bronze medal by the Royal Photographic Society in 1934, the Howard N. Potts Medal from the Franklin Institute in 1941, the Golden Plate Award of the American Academy of Achievement in 1966, the David Richardson Medal by the Optical Society of America in 1968, the Albert A. Michelson Medal from the same Franklin Institute in 1969, and the National Medal of Science in 1973. Edgerton partnered with Kenneth J. Germeshausen to do consulting for industrial clients. Later Herbert Grier joined them. The company name "Edgerton, Germeshausen, and Grier" was changed to EG&G; in 1947. EG&G; became a prime contractor for the Atomic Energy Commission and had a major role in photographing and recording nuclear tests for the US through the fifties and sixties. For this role Edgerton and Charles Wykoff and others at EG&G; developed and manufactured the Rapatronic camera. His work was instrumental in the development of side-scan sonar technology, used to scan the sea floor for wrecks. Edgerton worked with undersea explorer Jacques Cousteau, by first providing him with custom-designed underwater photographic equipment featuring electronic flash, and then by developing sonar techniques used to discover the Britannic. Edgerton participated in the discovery of the American Civil War battleship USS Monitor. While working with Cousteau, he acquired the nickname in photographic circles: "Papa Flash". In 1974 Doc Edgerton worked with Paul Kronfield in Greece on a sonar search for the lost city of Helike, believed to be the basis for the legend of Atlantis. Edgerton co-founded EG&G;, Inc., which manufactured advanced electronic equipment including side-scan sonars, subbottom profiling equipment. EG&G; also invented and manufactured the Krytron, the detonation device for the hydrogen bomb, and an EG&G; division supervised many of America's nuclear testing. In addition to having the scientific and engineering acumen to perfect strobe lighting commercially, Edgerton is equally recognized for his visual aesthetic: many of the striking images he created in illuminating phenomena that occurred too fast for the naked eye adorn art museums worldwide. In 1940, his high speed stroboscopic short film Quicker'n a Wink won an Oscar. Edgerton was appointed a professor of electrical engineering at the Massachusetts Institute of Technology (MIT) in 1934. In 1956, Edgerton was elected a Fellow of the American Academy of Arts and Sciences. He was especially loved by MIT students for his willingness to teach and his kindness: "The trick to education", he said, "is to teach people in such a way that they don't realize they're learning until it's too late". His last undergraduate class, taught during fall semester 1977, was a freshman seminar titled "Bird and Insect Photography". One of the graduate student dormitories at MIT carries his name. In 1962, Edgerton appeared on I've Got a Secret, where he demonstrated strobe flash photography by shooting a bullet into a playing card and photographing the result. Edgerton's work was featured in an October 1987 National Geographic Magazine article entitled "Doc Edgerton: the man who made time stand still". Family After graduating from the University of Nebraska-Lincoln, Edgerton married Esther May Garrett"Esther Edgerton, widow of 'Doc' Edgerton and benefactor of the Institute, dies at 98", MIT News, March 13, 2002 in 1928. She was born in Aurora, Nebraska on September 8, 1903 and died on March 9, 2002 in Charlestown, South Carolina. She received a bachelor's degree in mathematics, music and education from the University of Nebraska-Lincoln. A skilled pianist and singer, she attended the New England Conservatory of Music and taught in public schools in Aurora, Nebraska and Boston. During their marriage they had three children: Mary Louise (April 21, 1931), William Eugene (8/9/1933), Robert Frank (5/10/1935). His sister, Mary Ellen Edgerton, was the wife of L. Welch Pogue (1899–2003) a pioneering aviation attorney and Chairman of the old Civil Aeronautics Board. David Pogue, a technology writer, journalist and commentator, is his great nephew. Death Edgerton remained active throughout his later years, and was seen on the MIT campus many times after his official retirement. He died suddenly on January 4, 1990 at the MIT Faculty Club at the age of 86, and is buried in Mount Auburn Cemetery, Cambridge, Massachusetts. Legacy On July 3, 1990, in an effort to memorialize Edgerton's accomplishments, several community members in Aurora, Nebraska decided to construct a "Hands-On" science center. It was designated as a "teaching museum," that would preserve Doc's work and artifacts, as well as feature the "Explorit Zone" where people of all ages could participate in hands-on exhibits and interact with live science demonstrations. After five years of private and community-wide fund-raising, as well as individual investments by Doc's surviving family members, the Edgerton Explorit Center was officially dedicated on September 9, 1995 in Aurora. Edgerton Explorit Center At MIT, the Edgerton Center, founded in 1992, is a hands-on laboratory resource for undergraduate and graduate students, and also conducts educational outreach programs for high school students and teachers.Edgerton Center, MIT Works *Flash!

❤️ Harry Kroto 🐞

"Sir Harold Walter Kroto (born Harold Walter Krotoschiner; 7 October 1939 – 30 April 2016), known as Harry Kroto, was an English chemist. He shared the 1996 Nobel Prize in Chemistry with Robert Curl and Richard Smalley for their discovery of fullerenes. He was the recipient of many other honors and awards. Kroto held many positions in academia throughout his life, ending his career as the Francis Eppes Professor of Chemistry at Florida State University, which he joined in 2004. Prior to this, he spent approximately 40 years at the University of Sussex. Kroto promoted science education and was a critic of religious faith. Early years Kroto was born in Wisbech, Cambridgeshire, England, to Edith and Heinz Krotoschiner,Harold Walter Kroto Biography – life, family, parents, name, wife, school, mother, young, born, college, time, year, Studied Chemistry in College. Notablebiographies.com. Retrieved 25 December 2011. his name being of Silesian origin. His father's family came from Bojanowo, Poland, and his mother's from Berlin. Both of his parents were born in Berlin and fled to Great Britain in the 1930s as refugees from Nazi Germany; his father was Jewish. Harry was raised in Bolton while the British authorities interned his father on the Isle of Man as an enemy alien during World War II"Harold Kroto, Chemist who helped illuminate molecules, dies at 76"], The New York Times, 5 May 2016, pg. B14 and attended Bolton School, where he was a contemporary of the actor Ian McKellen. In 1955, Harold's father shortened the family name to Kroto. As a child, he became fascinated by a Meccano set. Kroto credited Meccano, as well as his aiding his father in the latter's balloon factory after World War II – amongst other things – with developing skills useful in scientific research. He developed an interest in chemistry, physics, and mathematics in secondary school, and because his sixth form chemistry teacher (Harry Heaney – who subsequently became a university professor) felt that the University of Sheffield had the best chemistry department in the United Kingdom, he went to Sheffield. Although raised Jewish, Harry Kroto stated that religion never made any sense to him. He was a humanist who claimed to have three religions: Amnesty Internationalism, atheism, and humour. He was a distinguished supporter of the British Humanist Association. In 2003 he was one of 22 Nobel Laureates who signed the Humanist Manifesto. In 2015, Kroto signed the Mainau Declaration 2015 on Climate Change on the final day of the 65th Lindau Nobel Laureate Meeting. The declaration was signed by a total of 76 Nobel Laureates and handed to then-President of the French Republic, François Hollande, as part of the successful COP21 climate summit in Paris. Education and academic career=Education Kroto was educated at Bolton School and went to the University of Sheffield in 1958, where he obtained a first-class honours BSc degree in Chemistry (1961) and a PhD in Molecular Spectroscopy (1964). During his time at Sheffield he also was the art editor of Arrows – the University student magazine, played tennis for the University team (reaching the UAU finals twice) and was President of the Student Athletics Council (1963–64). Among other things such as making the first phosphaalkenes (compounds with carbon phosphorus double bonds), his doctoral studies included unpublished research on carbon suboxide, O=C=C=C=O, and this led to a general interest in molecules containing chains of carbon atoms with numerous multiple bonds. He started his work with an interest in organic chemistry, but when he learned about spectroscopy it inclined him towards quantum chemistry; he later developed an interest in astrochemistry. After obtaining his PhD, Kroto spent two-years in a postdoctoral position at the National Research Council in Ottawa, Canada carrying out further work in molecular spectroscopy, and also spent the subsequent year at Bell Laboratories in New Jersey (1966–1967) carrying out Raman studies of liquid phase interactions and worked on quantum chemistry. Research at the University of Sussex In 1967, Kroto began teaching and research at the University of Sussex in England. During his time at Sussex from 1967 to 1985, he carried out research mainly focused on the spectroscopic studies of new and novel unstable and semi-stable species. This work resulted in the birth of the various fields of new chemistry involving carbon multiply bonded to second and third row elements e.g. S, Se and P. A particularly important breakthrough (with Sussex colleague John Nixon) was the creation of several new phosphorus species detected by microwave spectroscopy. This work resulted in the birth of the field(s) of phosphaalkene and phosphaalkyne chemistry. These species contain carbon double and triple bonded to phosphorus (C=P and C≡P) such as cyanophosphaethyne. In 1975, he became a full professor of Chemistry. This coincided with laboratory microwave measurements with Sussex colleague David Walton on long linear carbon chain molecules, leading to radio astronomy observations with Canadian astronomers revealing the surprising fact that these unusual carbonaceous species existed in relatively large abundances in interstellar space as well as the outer atmospheres of certain stars – the carbon-rich red giants. Discovery of buckminsterfullerene Buckminsterfullerene, C60 In 1985, on the basis of the Sussex studies and the stellar discoveries, laboratory experiments (with co- workers James R. Heath, Sean C. O'Brien, Yuan Liu, Robert Curl and Richard Smalley at Rice University) which simulated the chemical reactions in the atmospheres of the red giant stars demonstrated that stable C60 molecules could form spontaneously from a condensing carbon vapour. The co-investigators directed lasers at graphite and examined the results. The C60 molecule is a molecule with the same symmetry pattern as a football, consisting of 12 pentagons and 20 hexagons of carbon atoms. Kroto named the molecule buckminsterfullerene, after Buckminster Fuller who had conceived of the geodesic domes, as the dome concept had provided a clue to the likely structure of the new species. In 1985, the C60 discovery caused Kroto to shift the focus of his research from spectroscopy in order to probe the consequences of the C60 structural concept (and prove it correct) and to exploit the implications for chemistry and material science. This research is significant for the discovery of a new allotrope of carbon known as a fullerene. Other allotropes of carbon include graphite, diamond and graphene. Harry Kroto's 1985 paper entitled "C60: Buckminsterfullerine", published with colleagues J. R. Heath, S. C. O'Brien, R. F. Curl, and R. E. Smalley, was honored by a Citation for Chemical Breakthrough Award from the Division of History of Chemistry of the American Chemical Society, presented to Rice University in 2015. The discovery of fullerenes was recognized in 2010 by the designation of a National Historic Chemical Landmark by the American Chemical Society at the Richard E. Smalley Institute for Nanoscale Science and Technology at Rice University in Houston, Texas. Research at Florida State University In 2004, Kroto left the University of Sussex to take up a new position as Francis Eppes Professor of Chemistry at Florida State University. At FSU he carried out fundamental research on: Carbon vapour with Professor Alan Marshall; Open framework condensed phase systems with strategically important electrical and magnetic behaviour with Professors Naresh Dalal (FSU) and Tony Cheetham (Cambridge); and the mechanism of formation and properties of nano-structured systems. In addition, he participated in research initiatives at FSU that probed the astrochemistry of fullerenes, metallofullerenes, and polycyclic aromatic hydrocarbons in stellar/circumstellar space, as well as their relevance to stardust. Educational outreach and public service In 1995, he jointly set up the Vega Science Trust, a UK educational charity that created high quality science films including lectures and interviews with Nobel Laureates, discussion programmes, careers and teaching resources for TV and Internet Broadcast. Vega produced over 280 programmes, that streamed for free from the Vega website which acted as a TV science channel. The trust closed in 2012. Sir Harold Kroto at CSICon 2011 In 2009, Kroto spearheaded the development of a second science education initiative, Geoset. Short for the Global Educational Outreach for Science, Engineering and Technology, GEOSET is an ever-growing online cache of recorded teaching modules that are freely downloadable to educators and the public. The program aims to increase knowledge of the sciences by creating a global repository of educational videos and presentations from leading universities and institutions. In 2003, prior to the Blair/Bush invasion of Iraq on the pretext that Iraq had weapons of mass destruction, Kroto initiated and organised the publication of a letter to be signed by a dozen UK Nobel Laureates and published in The Times. It was composed by his friend the Nobel Peace Prize Laureate the late Sir Joseph Rotblat and published in The Times on 15 February 2003. He wrote a set of articles, mostly opinion pieces, from 2002–2003 for the Times Higher Education Supplement, a weekly UK publication. From 2002–2004, Kroto served as President of the Royal Society of Chemistry.RSC Presidents 1980 to Present Day. Rsc.org. Retrieved 25 December 2011. In 2004, he was appointed to the Francis Eppes Professorship in the chemistry department at Florida State University, carrying out research in nanoscience and nanotechnology. He spoke at Auburn University on 29 April 2010, and at the James A. Baker III Institute for Public Policy at Rice University with Robert Curl on 13 October 2010.James A.

In October 2010 Kroto participated in the USA Science and Engineering Festival's Lunch with a Laureate program where middle and high school students had the opportunity to engage in an informal conversation with a Nobel Prize–winning scientist.. usasciencefestival.org He spoke at Mahatma Gandhi University, at Kottayam, in Kerala, India in January 2011, where he was an 'Erudite' special invited lecturer of the Government of Kerala, from 5 to 11 January 2011.Erudite. Mgu.ac.in. Retrieved 25 December 2011. Kroto spoke at CSICon 2011, a convention "dedicated to scientific inquiry and critical thinking" organized by the Committee for Skeptical Inquiry in association with Skeptical Inquirer magazine and the Center for Inquiry. He also delivered the IPhO 2012 lecture at the International Physics Olympiad held in Estonia. In 2014, Kroto spoke at the Starmus Festival in the Canary Islands, delivering a lecture about his life in science, chemistry, and design. Personal life In 1963, he married Margaret Henrietta Hunter, also a student of the University of Sheffield at the time. The couple had two sons: Stephen and David. Throughout his entire life, Kroto was a lover of film, theatre, art, and music and published his own artwork. Personal beliefs Kroto was a "devout atheist" who thought that beliefs in immortality derive from lack of the courage to accept human mortality. He was a patron of the British Humanist Association. He was a supporter of Amnesty International. He referred to his view that religious dogma causes people to accept unethical or inhumane actions: "The only mistake Bernie Madoff made was to promise returns in this life." He held that scientists had a responsibility to work for the benefit of the entire species. On 15 September 2010, Kroto, along with 54 other public figures, signed an open letter published in The Guardian, stating their opposition to Pope Benedict XVI's state visit to the UK. Kroto was an early Signatory of Asteroid Day. In 2008, Kroto was critical of Michael Reiss for directing the teaching of creationism alongside evolution. Kroto praised the increase of organized online information as an "Educational Revolution" and named it as the "GooYouWiki" world referring to Google, YouTube and Wikipedia. One of Kroto's favourite quotes was: "I believe in Spinoza's God who reveals himself in the orderly harmony of what exists, not in a God who concerns himself with the fates and actions of human beings." said by Albert Einstein, Graphic design The discovery of buckminsterfullerene caused Kroto to postpone his dream of setting up an art and graphic design studio – he had been doing graphics semi-professionally for years. However, Kroto's graphic design work resulted in numerous posters, letterheads, logos, book/journal covers, medal design, etc. He produced artwork after receiving graphic awards in the Sunday Times Book Jacket Design competition (1964) and the Moet Hennesy/Louis Vuitton Science pour l'Art Prize (1994). Other notable graphical works include the design of the Nobel UK Stamp for Chemistry (2001) and features at the Royal Academy (London) Summer Exhibition (2004). Death and reactions Kroto died on 30 April 2016 in Lewes, East Sussex from complications of amyotrophic lateral sclerosis at the age of 76. Richard Dawkins wrote a memorial for chemist Kroto where he mentioned Kroto's "passionate hatred of religion." The Wall Street Journal described him as "(spending much of his later life) jetting around the world to extol scientific education in a world he saw as blinded by religion." Slate's Zack Kopplin related a story about how Kroto gave him advice and support to fight Louisiana's creationism law, a law that allows public school science teachers to attack evolution and how Kroto defended the scientific findings of global warming. In an obituary published in the journal Nature, Robert Curl and James R. Heath described Kroto as having an "impish sense of humour similar to that of the British comedy group Monty Python".
