Dendrochronology is the scientific method of dating tree rings to the exact year they were formed in a tree. As well as dating them, this can give data for dendroclimatology, the study of climate and atmospheric conditions during different periods in history from the wood of old trees. Dendrochronology derives from the Ancient Greek dendron, meaning "tree", khronos, meaning "time", and -logia, "the study of".
Quantitative research is a research strategy that focuses on quantifying the collection and analysis of data. It is formed from a deductive approach where emphasis is placed on the testing of theory, shaped by empiricist and positivist philosophies.
In the study of past climates ("paleoclimatology"), climate proxies are preserved physical characteristics of the past that stand in for direct meteorological measurements and enable scientists to reconstruct the climatic conditions over a longer fraction of the Earth's history. Reliable global records of climate only began in the 1880s, and proxies provide the only means for scientists to determine climatic patterns before record-keeping began.
The works of J. R. R. Tolkien have generated a body of research covering many aspects of his fantasy writings. These encompass The Lord of the Rings and The Silmarillion, along with his legendarium that remained unpublished until after his death, and his constructed languages, especially the Elvish languages Quenya and Sindarin. Scholars from different disciplines have examined the linguistic and literary origins of Middle-earth, and have explored many aspects of his writings from Christianity to feminism and race.
The Smoke Ring is a 1987 science fiction novel by Larry Niven. Like much of Niven's work, the story is heavily influenced by the setting: a gas torus, a ring of air around a neutron star. It is a sequel to The Integral Trees.
Near-death studies is a field of psychology and psychiatry that studies the physiology, phenomenology and after-effects of the near-death experience (NDE). The field was originally associated with a distinct group of North American researchers that followed up on the initial work of Raymond Moody, and who later established the International Association for Near-Death Studies (IANDS) and the Journal of Near-Death Studies. Since then the field has expanded, and now includes contributions from a wide range of researchers and commentators worldwide. Research on near-death experiences is mainly limited to the disciplines of medicine, psychology and psychiatry.
Hockey stick graphs present the global or hemispherical mean temperature record of the past 500 to 2000 years as shown by quantitative climate reconstructions based on climate proxy records. These reconstructions have consistently shown a slow long term cooling trend changing into relatively rapid warming in the 20th century, with the instrumental temperature record by 2000 exceeding earlier temperatures.
Berberine is a quaternary ammonium salt from the protoberberine group of benzylisoquinoline alkaloids
This is a list of all published works of the English writer and philologist J. R. R. Tolkien. Tolkien's works were published before and after his death.
Tolkien Studies: An Annual Scholarly Review is an academic journal founded in 2004 publishing papers on the works of J. R. R. Tolkien. The journal's founding editors are Douglas A. Anderson, Michael D. C. Drout, and Verlyn Flieger, and the current editors are Michael D. C. Drout, Verlyn Flieger, and David Bratman. It states that it is the first scholarly journal published by an academic press in the area of Tolkien research.
Lantana camara is a species of flowering plant within the verbena family (Verbenaceae), native to the American tropics. It is a very adaptable species, which can inhabit a wide variety of ecosystems; once it has been introduced into a habitat it spreads rapidly; between 45ºN and 45ºS and more than 1,400 metres in altitude.
J. R. R. Tolkien's bestselling fantasy novel The Lord of the Rings had an initial mixed literary reception. Despite some enthusiastic early reviews from supporters such as W. H. Auden, Iris Murdoch, and C. S. Lewis, literary hostility to Tolkien quickly became acute and continued until the start of the 21st century. From 1982, Tolkien scholars such as Tom Shippey and Verlyn Flieger began to roll back the hostility, defending Tolkien, rebutting the critics' attacks and analysing what they saw as good qualities in Tolkien's writing.
The Cedars Natural Area Preserve is a Natural Area Preserve located in Lee County, Virginia. It protects rare plant and animal species adapted to the unique conditions of a karst landscape.
The divergence problem is an anomaly from the field of dendroclimatology, the study of past climate through observations of old trees, primarily the properties of their annual growth rings. It is the disagreement between instrumental temperatures and the temperatures reconstructed from latewood densities or, in some cases, from the widths of tree rings in far northern forests.
Keith Raphael Briffa was a climatologist and deputy director of the Climatic Research Unit. He authored or co-authored over 130 scholarly articles, chapters and books. In his professional work, he focused on climate variability in the late Holocene, with a special focus on northern portions of Europe and Asia. Briffa's preferred method was dendroclimatology, which is a set of procedures intended to decode information about the past climate from tree rings. Briffa helped develop data sets from trees from Canada, Fennoscandia, and northern Siberia which have been used in climate research.
Janet Brennan Croft is an American librarian and Tolkien scholar, known for her authored and edited books and journals on J. R. R. Tolkien's Middle-earth fantasy.
Dendropyrochronology is the science of using tree-ring dating to study and reconstruct the history of wild fires. It is a subfield of dendrochronology, along with dendroclimatology and dendroarchaeology.
The Shinan ship was a 14th-century Chinese ship that sank near what are today the Shinan islands, South Korea, around the year 1323, and was discovered in 1975. It was likely to have been part of a trade fleet between Port Ningbo, Yuan dynasty China and Port Hakata, Kamakura shogunate of Japan.
Rosanne D'Arrigo is a professor at Lamont–Doherty Earth Observatory at Columbia University known for her research into climate change using dendrochronology, or dating based on tree rings.
The Worlds of J. R. R. Tolkien: The Places that Inspired Middle-earth is a 2020 non-fiction book by the journalist and Tolkien scholar John Garth. It describes the places that most likely inspired J. R. R. Tolkien to invent Middle-earth, as portrayed in his fantasy books The Hobbit and The Lord of the Rings. Those places include many that Tolkien lived in or visited in his early life, as well as sites from history and literature. Most are real, for instance with England as the counterpart of the Shire, though some, like Atlantis, are mythical, and others, like Mirkwood, probably have roots in real places. He notes the ambiguities in some of the connections, and that others have made superficial comparisons, such as of Tolkien's towers with various modern towers in Birmingham, where Tolkien lived as a child. Garth presents his theories of the likely origins of some of these places, supporting these with maps and photographs.
