Progress of science and technology since 1945: development and impactScience and technology since 1945 Have you ever seen a snowball on a hill? He usually puts ice on his path, essentially running over someone before he gets bigger and bigger.


In many ways, the advance of science and technology since the Second World War (World War II) has acted like that snowball: some small advances and technological advances have resulted in even more innovation and new devices that reach the market Are. Fast pace every day.


This is how we can handle computers in just half a century to connect machines to the size of an apartment. This lesson will detail some amazing advances in the world of science and technology since World War II.


Communication and dissemination of information is now so ubiquitous that we rarely realize the continuous flow of information. Before World War II, radio was the main form of home communication equipment in most people’s homes.


There were televisions, but in general they were very expensive and had few programming options. Television exploded in popularity in the 1950s, allowing people to see important events as they occurred in real time.


For example, many Americans saw Neil Armstrong landing on the moon in 1969 from the comfort of his own sofa. Similarly, the coronation of Queen Elizabeth II in 1953 allowed many British residents to witness the pomp and circumstances surrounding the royal coronation for the first time.


As the decade began, television technology improved more and more, as color television replaced original black and white television in the 1970s. Accessories such as cassette recorders (VCR) were mounted on the screen and the definitions fell.


In the 1990s, high-definition (HD) televisions reached the market, producing a clearly sharper and more vibrant image than before, although before HD televisions became household items in the United States. It has been almost a decade.


The telephone experienced an equally rapid increase in use and technological development after World War II. With the invention of Alexander Graham Bell at the end of the 19th century, telephones became increasingly popular.


And the telegraph was largely replaced by World War II, with around 30 million telephones in service in 1948. After the World War II, the use of the phone continued to expand rapidly and until the 1970s. 100 million phones were in use.


The next significant advance in telephone communication occurred in the 1990s with the proliferation of cell phones. Although portable and in-vehicle phones were used since the 1940s, the first true cell phones (that is, one that a pedestrian could carry with them) did not arrive until the 1980s.


And they were still relatively large. They were Clooney items. They were very expensive for the average person. This changed in the 1990s as cell phones became smaller, faster and cheaper.


The proliferation of text messages in the early 2000s transformed the cell phone into a multipurpose device. The creation of smartphones, and especially Apple’s iPhone.


Which essentially converts cell phones into computers, has completely replaced cell phones, accessing the world of information on a device that only decades ago. It is used to make calls. telephone.


Transport World Transport has seen similar improvements in technology since World War II, although not nearly the same level of innovation. In fact, our main modes of transport (cars, airplanes, trains or ships) are the same.


Although all have undergone serious changes to improve safety and efficiency. However, scientists have recognized that there has been a person-to-person transmission between people who have not gone to animal markets.


The infected person in Vietnam was not related to China at all, but was a member of the family of someone infected in Wuhan. This means that an animal infection probably learned to jump on humans (from snakes) and then spread to our species.


Who has the greatest risk? In the cases in China, it is reported that 21% are seriously ill and, according to previous estimates, 3% of those infected died.

The first 17 people who died from the virus were between 48 and 89 years old.


Wwith an average age of 73 years. Thirteen (76%) were men and four (24%) were women. Most of those who die from the virus show underlying health conditions, and we know for sure in the case of ten people whose health information has been disclosed.


These people suffered from several chronic conditions, such as hypertension (41%), diabetes (29%), stroke (18%), as well as chronic obstructive pulmonary disease, coronary artery disease, chronic kidney disease and Parkinson’s disease.


We already live among coronavir: four other human coronaviruses (HCoV-229E, HCoV-OC43, HCoV-NL63 and HCoV-HKU1) cause colds, flu-like illnesses and serious respiratory diseases such as pneumonia.


Viral pneumonia is a combination of lung virus infection and our body’s immune response to that damage. There are also two more notable coronavir that jump from animals to infect human hosts.


SARS (severe acute respiratory syndrome) and MERS (Middle East respiratory syndrome). Reduce your risk of coronavirus infection.

How does 2019-nCoV spread? Scientists have no idea.


Where the new virus originally came from. They think it originated in animals, but the tests have not yet confirmed a specific animal host. Genome analysis suggests that it has recently emerged in humans.


So what host were humans in contact with? And how was it transmitted to humans? 2019-NCOV seems to be a respiratory virus, since the disease mainly affects the lungs.


So it is likely to spread through the same routes as colds and flu: sneezing and coughing in the air or falling into the hands that touch those surfaces OR when touching our eyes, nose or mouth after contact with contaminated surfaces.


Urine, feces and blood droplets can also be contagious. Contact with these substances, directly from people when they are contagious, or indirectly from surfaces contaminated with these body substances, can cause infection.


That is why the rapid isolation of suspicious cases and rapid infection control practices are very important, especially if it appears on this tab. This means that they produce large amounts of viruses and are unusually contagious.

Protect yourself and others from getting sick … How contagious is the 2019.


The WHO estimates that the reproductive number (R0) of coronavirus is 1.4 to 2.5. This means that an infected person has the ability to infect 1.4–2.5 susceptible people. But this figure may change as it develops.


New species of carnivorous dinosaurs revealed: Allosaurus jimmadseni: (1990) A new species of carnivorous theropod dinosaur has been identified from fossil remains discovered in northeastern Utah and Wyoming, United States, in the 1990s.


A group of Zimdaseni allosaurus attacks juvenile sauropod dinosaurs. The most recently discovered dinosaur is Elosauridae, a small to large body, a group of two open carnivorous dinosaurs that live in the Jurassic and Cretaceous periods.


The Dlod Eloosaurus Zimdaseni, who lived in the alluvial plains of western North America during the Jubasic period. The old creature was up to m m (-26-90 feet) long and had a total of 8.8 metric tons.


It had relatively long legs and tails and long arms with three sharp claws. 155 million years ago, Elosaurus jimdaseni is the geographically oldest species of Eloosaurus, which predicts the most famous delicate center of Eloosaurus.


The new species are distinguished by many unique features, with less arrest for reaching the slap from the top of the eye and a relatively narrow back of the flat surface hair under the upper hair under the eye.


His skull was weaker with an area of overlapping field smaller than that of the small allosaurus fragilis. “Previously, archaeologists thought that Jurassic is the only species of Allosaurus in North America.


But this study shows two species: the recently described Eleosaurus jimdaseni evolved at least a million years ago from his brother Kanzin, Allosaurus fragilis,” said Dr.. Mark Lowen, paleontologist at the Utah Museum of Natural History and the University of Utah.


The skull of Allosaurus jimdaseni becomes lighter than its previous relative Allosaurus fragilis, which suggests a slightly different behavior. The skeleton and skull of Allosaurus was discovered as a cast of skeletons.


And skulls and is now displayed on the Dinosaur National Monument in Utah. Dr. Lowen and his friend, Dr. Daniel Chure, a retired paleontologist from the Dinosaur National Monument, described the new species of two well-preserved skeletons and skulls.


The first sample was Dr. George Engleman met on the contracted paleontological list of the Morrison Formation of the Morrison National Monument in northeastern Utah on July 15, 1990 – 1990 from the University of Nebraska.


The second commercial fossil collection collection was found by Cyber + Cyber, Ltd. in Howe Quarry, Morrison Fermentation, Wyoming, in 199 199.

“Identifying a new species of rock dinosaur.


And that has been under intense research for more than 150 years is an excellent discovery experience,” said Dr. Chure. Eloosaurus Zimdaseni is a great example of how much more we need to know about the world of dinosaurs.


There are still more exciting fossils waiting to be discovered in the jurassic rocks of the American West. The team article was published in Peerage magazine.


Coronavirus 2019-nCoV recently identified: this is what you need to know: The current outbreak of viral pneumonia in Wuhan, caused by the fast-growing city of Hubei Province.


And the traffic center of central China, is due to a new coronavirus called 2019-nCoV by the World Health Organization (WHO ). Image 2019-TEM of nCoV particles. How many people have been infected worldwide? 2,744 cases have been confirmed in mainland China and 80 people have died.


There are complete or partial blockages in 15 Chinese cities in an effort to limit the spread of 2019-nCoV. More than 50 cases have been confirmed in the United States, Malaysia, Singapore, Thailand, France, Australia.


And worldwide. The center of the outbreak seems to be a market for shellfish and live animals in Wuhan. Initially it was thought that the transmission of infected animals to people in the market was limited to those without individuals or individuals.


However, scientists have learned that there has been a person-to-person transmission between people who have not moved to animal markets.

The infected person in Vietnam did not belong to China at all.


But was a member of the family of someone infected in Wuhan. This means that an animal infection probably learned to jump on humans (from snakes) and then spread to our species.


Who has the greatest risk? Of the cases in China, it is reported that 21% are seriously ill and, according to previous estimates, 3% of those infected died.


The first 17 people who died from the virus were between 48 and 89 years old, with an average age of 73 years. Thirteen (76%) were men and four (24%) were women.


Most of those who have died from the virus show underlying health conditions, and we know for sure in the case of ten people whose health information has been disclosed.


These people suffered from several chronic conditions, such as hypertension (41%), diabetes (29%), stroke (18%), as well as chronic obstructive pulmonary disease, coronary artery disease, chronic kidney disease and Parkinson’s disease.

There are also two more notable coronaviruses that jumped from the animals to infect human hosts: SARS (severe acute respiratory syndrome) and MERS (Middle East respiratory syndrome).


Reduce your risk of coronavirus infection. How does 2019-nCoV spread? Scientists have no idea where the new virus originally came from. They think it originated in animals, but the tests have not yet confirmed a specific animal host.

This means that an infected person has the ability to infect 1.4–2.5 susceptible people. But this figure can change as an outbreak develops.


In comparison, SARS had a suspicious reproduction number of 2 to 5. This meant that an infected person could infect five susceptible people. So 2019-nCoV seems to be less infectious than SARS.


The risk of SARS transmission in the disease was greater at five to ten days. If people quickly isolated themselves in their disease, after showing symptoms, they were unlikely to infect someone else.


But one study showed that it was possible to be contagious with 2019-nCoV without showing symptoms. This increases the possibility of transmitting the virus to others, without the knowledge that an infected person becomes ill.


This would make it very difficult for health authorities to identify and isolate infectious people and control outbreaks. Development of a clinical trial.

Chinese scientists sequenced the 2019-nCoV genome and, in a matter of days, shared that information with the world.


This allowed researchers in Germany to quickly develop and openly share a part of the specific nucleic acid tests that sensitively identify viruses by detecting small amounts of their RNA.


Researchers in Hong Kong and the Chinese Center for Disease Control then published their tests separately.
