History of Photography and the Camera:      The basic concept of photography has been around since about the 5th century B.C.E. It wasn't until an Iraqi scientist developed something called the camera obscura in the 11th century that the art was born.      Even then, the camera did not actually record images, it simply projected them onto another surface. The images were also upside-down, though they could be traced to create accurate drawings of real objects such as buildings.      The first camera obscura used a pinhole in a tent to project an image from outside the tent into the darkened area. It was not until the 17th century that the camera obscura became small enough to be portable. Basic lenses to focus the light were also introduced around this time.           During the 1800s, Britain and France were neck and neck in the race to get early photographic technology off the ground. The French initially pippe...

    History of Chemistry         Chemistry is a branch of science that has been around for a long time. In fact, chemistry is known to date back to as far as the prehistoric times. Due to the amount of time chemistry takes up on the timeline, the science is split into four general chronological categories. The four categories are: prehistoric times - beginning of the Christian era (black magic), beginning of the Christian era - end of 17th century (alchemy), end of 17th century - mid 19th century (traditional chemistry) and mid 19th century - present (modern chemistry).                                             The history of chemistry represents a time span from ancient history to the present. By 1000 BC, civilizations used technologies that would eventually form the basis of the various branches of chemistry. Examples include extractin...

History of Languages It seems that academics and professionals are still not entirely sure of how old language is, but general consensus us that it has been with us since around 100 000 BC. As a result of this disagreement, it is even harder to accept which is the oldest surviving language. That is, one that is still in use in our modern world. Currently, about 7,000 languages are spoken around the world. They belong to different language families and their origins date back thousands of years ago. Researchers are still finding it difficult to determine which language is the oldest. However, the earliest written languages on record are the cuneiform script that was discovered in Mesopotamia that dates back to 8th millennium BC. The Sumerian script that started in the 3rd millennium BC was developed for funerary inscriptions because the Sumerians were concerned about their afterlife. Early History For centuries, humans have wondered about the origins of language and yet nobody is ...

History of Dinosaurs                         Dinosaurs first appeared between 247 and 240 million years ago. They ruled the Earth for about 175 million years until an extinction event 65.5 million years ago wiped out all of them, expect for the avian dinosaurs. Scientists don't agree entirely on what happened, but the extinction likely was a double or triple whammy involving an asteroid impact, choking chemicals from erupting volcanoes, climate change and possibly other factors. Dinosaurs are a varied group of animals from taxonomic, morphological and ecological standpoints. Birds, at over 10,000 living species, are the most diverse group of vertebrates besides perciform fish. Using fossil evidence, paleontologists have identified over 500 distinct genera and more than 1,000 different species of non-avian dinosaurs. Dinosaurs are represented on every continent by both extant species (birds) and fossil remains. ...

History of Cricket          Early Cricket (Pre 1799) There is a consensus of expert opinion that cricket may have been invented during Saxon or Norman times by children living in the Weald, an area of dense woodlands and clearings in south-east England. The first reference to cricket being played as an adult sport was in 1611, and in the same year, a dictionary defined cricket as a boys' game. There is also the thought that cricket may have derived from bowls, by the intervention of a batsman trying to stop the ball from reaching its target by hitting it away. Village cricket had developed by the middle of the 17th century and the first English “county teams” were formed in the second half of the century, as “local experts” from village cricket were employed as the earliest professionals. The first known game in which the teams use county names is in 1709.  Cricket was introduced to North America via the English colonies as early as the 17th century,...

  History of Mathematics           Mathematics In Ancient Egypt Mathematics, the science of structure, order, and relation that has evolved from elemental practices of counting, measuring, and describing the shapes of objects. It deals with logical reasoning and quantitative calculation, and its development has involved an increasing degree of idealization and abstraction of its subject matter. Since the 17th century, mathematics has been an indispensable adjunct to the physical sciences and technology, and in more recent times it has assumed a similar role in the quantitative aspects of the life sciences. In many cultures under the stimulus of the needs of practical pursuits, such as commerce and agriculture mathematics has developed far beyond basic counting. This growth has been greatest in societies complex enough to sustain these activities and to provide leisure for contemplation and the opportunity to build on the achievements of earlier mat...

   History of DNA           DNA was first isolated by the Swiss physician Friedrich Miescher who, in 1869, discovered a microscopic substance in the pus of discarded surgical bandages. As it resided in the nuclei of cells, he called it "nuclein". In 1878, Albrecht Kossel isolated the non-protein component of "nuclein", nucleic acid, and later isolated its five primary nucleobases.           In 1909, Phoebus Levene identified the base, sugar, and phosphate nucleotide unit of the RNA (then named "yeast nucleic acid").  In 1929, Levene identified deoxyribose sugar in "thymus nucleic acid" (DNA). Levene suggested that DNA consisted of a string of four nucleotide units linked together through the phosphate groups ("tetranucleotide hypothesis"). Levene thought the chain was short and the bases repeated in a fixed order.            In 1927, Nikolai Koltsov proposed that inherited...

History of Coronavirus Discovery:        Coronaviruses were first discovered in the 1930s when an acute respiratory infection of domesticated chickens was shown to be caused by infectious bronchitis virus. Arthur Schalk and M.C. Hawn described in 1931 a new respiratory infection of chickens in North Dakota. The infection of new-born chicks was characterized by gasping and listlessness. In the 1940s, two more animal coronaviruses, mouse hepatitis virus (MHV) and transmissible gastroenteritis virus (TGEV), were isolated.             The history of human coronaviruses began in 1965 when Tyrrell and Bynoe found that they could passage a virus named B814. It was found in human embryonic tracheal organ cultures obtained from the respiratory tract of an adult with a common cold.   https://journals.lww.com/pidj/fulltext/2005/11001/history_and_recent_advances_in_coronavirus.12.aspx           In the abo...
