10 incredible inventions of ancient Greeks

Ancient Greek culture is, in many ways, considered to be one of the world's leading cultures ever - and the technology sector is not excluded from all of the areas where it has excelled, with many inventions of the ancient Greek world "coming" until today.

Here are some of them, for which (perhaps) you would not expect that they were living in the ancient Greek world.

Hydraulic clock (clock): Inquisition of Alexandros Ktimacios, considered as one of the pioneers of automation. It was based on the beginning of the hourglass and could be used at night or overcast (generally without the sun).

Fire pump: And this was based on the invention of Kthyzhiou, who created the manual pump, which has arrived to our days (after Ktissibiou perfected it as a fire pump by Heron). Generally, Kthybis had been very busy with the pressure of air and fluids, with a range of inventions ranging from compressed-air weapons to lifts and a ... fit!

Odometer: It is believed to have been a creation of the Heron of Alexandria, and it was a construction that could be transported to wheeled vehicles to record distances.

Central Heating: It is said that the Temple of Artemis in Ephesus - one of the Seven Wonders of the Ancient World - was heated by pipelines that were on the floor and made the heat generated by fires circulated.

The robot: Filon the Byzantium, a pupil of Ktesiviou, is considered to be the "link" between Ktesiwi and Heron, such as a horse who drank water, a little girl who buzzed water, a maid, etc. This work was continued by the famous Heron the Alexandrian (1st nd-1st century AD), who created a large number of mobile devices - eg a mobile automatic theater. His work describes in detail the "Automated", the oldest known text with descriptions of automatic mechanical systems that could make programmed movements.

Lever: "Let me go and I can move" (give me somewhere to stand and move the Earth). Archimedes' famous plot is about discovering the lever-something so simple, and at the same time so wondrous.

Hydraulic wheel: A water pumping system attributed to Dimitrios Poliorketas (one of Alexander the Great's successors, best known for his besieging machines).

Alarm clock: It is said that Aristotle had made it to wake up quickly and study more. They consisted of a container of water that emptied with a selected flow rate (in each case) into another container carrying a hinged hemispheric float. At the predetermined moment of filling the container the float was overturned and the beads placed on its flat surface fell into a cup (or dish) causing noise. A similar device was the "Plato's alarm clock".

The Music Mirror: Another Kitesivi's work - a height-adjustable mirror that could balance in any location, producing musical notes at the same time.

The Archimedes steam cannon: It consisted of a metal cylindrical boiler that was connected to it with a closed water container. The boiler at its open end had a wooden barrel embedded in the stone bullet to be ejected. The barrel encrusted with a wooden beam secured with two trusses. When the boiler had reached the appropriate temperature with fire, the tap was opened, the water dropped to the boiler, evaporated rapidly, the wooden beams broke and the bullet was thrown.

Samsung puts 64MP camera Sensor In Midrange Smartphone

Samsung is reportedly going to equip one of its midrange choices with the largest smartphone digital camera thus far.

in keeping with Korean IT news web site ETNews, Samsung Electronics in planning to equip the upcoming Galaxy A70S smartphone with the Isocell vivid GW1 sensor, a digital camera boasting sixty four megapixels.

Tom’s book mentioned that this new digital camera nonetheless retains the 0.eight-micrometer pixel dimension featured in Samsung’s latest 20-megapixel sensors. mixed with Samsung’s other applied sciences such as tetracell technology and remosaic algorithm, the new 64-megapixel sensor can produce tremendous pictures taken in low-gentle circumstances.

The Verge said that the brand new sixty four-megapixel sensor can descramble the color filter so as to produce gold standard full-resolution 64-megapixel photos in decent light.

Samsung’s Isocell vivid GW1 sensor overtakes the biggest smartphone digicam in the market today, which is Sony’s 48-megapixel IMX586 sensor. This makes Samsung the chief in smartphone camera technology -- except Sony, of course, decides to liberate an excellent greater one.

Why a midrange mobile?

Samsung is expected to unencumber the Galaxy A70S midrange smartphone sometime within the second half of 2019. This new telephone will change the at present current Galaxy A70 which points three cameras at the again: a 32-megapixel sensor, an eight-megapixel extremely-huge attitude digicam, and a 5-megapixel depth digicam.

This isn’t the first time the Korean tech significant has determined to introduce new applied sciences using a midrange equipment. The Galaxy A9 smartphone, which became released ultimate yr, become the first smartphone to characteristic 4 cameras established in the back of the cell. TechRadar noted this quad-digicam setup become “brilliant.”

through the use of a midrange product, Samsung may be in a position to consider how its new expertise works in true-existence minus the possibility of a massive flop. The A70S should be a midrange offering, in spite of everything, no longer like the Galaxy Fold smartphone which, as everyone knows, is dealing with loads of hiccups -- together with a likely cancellation -- thus far.

prior, a rumor went out about Samsung releasing its “most creative” product yet, one which will surpass the aforementioned Galaxy Fold in terms of creativity. The supply of the rumor, the renowed leaker normal only as “IceUniverse,” also referred to those who desire “new issues” from Samsung stronger be careful for new Galaxy A fashions.

might the upcoming Galaxy A70S with a sixty four-megapixel digital camera be that “creative” equipment? simplest time will tell. reside tuned for greater updates on the Galaxy A70S and Galaxy Fold instruments.

Milky Way

A white stripe in the night sky, especially visible in the dark without the moon at night. This is because the autumn evenings run across the sky from northeast to southwest, i.e. roughly coincides with the departure of migratory birds. According to written sources, the first attempt was made to scientifically explain the Bird's Path in ancient Greece. What is actually the Milky Way, the first to understand Pythagoras in the VI century. pr. Kr. He insisted that it was a pool of many weak stars whose eyes could not be seen in isolation. G. Galilee convinced him, looking at the Milky Way through his invented telescope.

The Milky Way is a projection of a giant star system in the sky, as demonstrated by the English astronomer William Hitchel in the 18th century, relying on the stars' calculations in various directions of the sky. The first true model of this star system was created only in the twentieth century. early in the year. The galaxy consists of hundreds of billions of stars, their swarms, interstellar gases, and dust clouds called the Shadows. Similar galaxies spread in all directions from it are numerous. So this galaxy is no different in the universe. We will continue to call the Galaxy of the Milky Way galaxy.

The sun is running around the planet with its planets around the Galactic Center in the direction of Sagittarius constellation and away from us at 28,000. The stars of the galaxy are the most densely clustered part of the disc-shaped space. The diameter of this disc is about 100,000. Because the Sun is inside it, the other distant disc stars come together in a glowing circle - the Bird Path that divides the sphere of the sky into two approximately equal parts. If the stars on the Galaxy were of the same density and if the interstellar space were transparent, the Bird Trail would look like a middle-lined strip. However, the density of stars is uneven, and there are clouds of light-absorbing dust in the interstellar space. As a result, the Bird's Trail looks like a bright strip of very irregular contours, narrowing, widening or splitting into several furrows.

The Bird's Trail is the narrowest and shimmers in the winter and spring when it travels through the constellations of the Great Dog, Unicorn, Twins, Carrier, Persia, Casasopia and Cefee. The part of the Milky Way that is visible in summer and autumn is much brighter. The Swan Constellation The Bird Trail's continuous band breaks down into two furrows. One of them flickering through the corners of the constellations of Lapps and Hercules and disappears at the constellation of the Snake Head. The second gang extends through the constellations of Strule, Eagle, Shield and finds himself in the constellation of Sagittarius. Further to the south, the Paukščių Takas part of the geographical latitude of Lithuania is not visible. In the southern hemisphere, it extends from the Great Dog and through Laagagal, Sail, Kilio, Centaurus, Cross, Campain, Scorpio's constellations are coming closer to Sagittarius on the other side.

The Sagittarius constellation The Bird Trail is the widest and brightest, there is the Galactic Center. In the opposite direction, its direction is called the anticenter and lies at the boundary of the Carrier and Taurus constellations. Approximately in the middle of the Milky Way is the galaxy halfway, from which galaxy width b is counted in both directions: it equals 0o on the equator, the north and south pole of the galaxy (the first - the constellation of Berenicus, the second - the constellation of Sculptor) + 90o and - 90o. The Galactic Length l is measured by the arc along the Galactic Equator from the direction of the Galactic Center to the West East from 0o to 360o.

Structure of the galaxy:

The galactic disc is just one of the two components of the galactic. It is surrounded on all sides by a smaller density spheroid with a diameter much larger than the disc. The radius of the latter is about 50,000, and the spheroid is about 80,000. The spheroid is slightly flattened - its pendulum radius is equal to a radius of 0.8 in the plane of the disc. The disc and spheroid centers overlap. The density of disc stars increases as it approaches its plane, and the density of spheroid stars is approaching the center of the galaxy. The disc is thickening towards the center. In this way, a central star body with a radius of about 8,000 is formed around the Galactic Center. In it, the stars are denser times more than the sun. Their orbit is an elongated ellipse, tilted at a wide angle to the disc plane. It is believed that the Galactic Center has a black abyss with a mass of about 5 · 106 M. It is surrounded by a few light-years of hot rotating hot plasma spin.
There are about 250 billion stars in the Galaxy, 90% of them on disk, 5% on spheroids and 5% on central. There are still gas and dust clouds in the galaxy disk and in the central pool, which make up 1/50 of the total mass of the stars.

The stars and nebulae that make up the galactic disk run around the center of the galactic orbit in orbit. The distance between each star and the nebula from the center is equivalent to a certain orbital speed. If the speed of the run would be just proportional to the distance, then the Galaxy would turn like a solid body like a gramophone plate. However, this is not the case - the dependence of its rotation speed on the center distance is difficult. With a solar distance from the center of the galactic center (28,000), the speed is 220 km / s, so it turns once around the center at over 230 million. years. Almost all of the stars in the galactic disc have a chemical composition similar to that of the Sun.

Our Galaxy is a spiral system. Its disk has large masses of hot stars, supermillas, and gas and dust clouds in spiral-shaped wires. Smaller mass stars spread across the disc. The sun is in the so-called Orion Spiral. The closest to the center of the galaxy is the Sagittarius's viola, and on the anticentre's side - the vie.

The stars of the galactic spheroid also fly around its center, but each one individually. Their orbits, mostly very elongated ellipses, form a wide range of angles with the plane of the disc (like the stars of the central body).

The closest to the center are the spheroidal orbit points - the perpendiculars - somewhere in the central reservoir, and the farthest - the apogalts - on the edges of the galaxy. These stars are around the center around 100 million. years. The galaxy's spheroidal crumb masses are smaller than the Sun's mass, and their outer layers have heavy elements between 100 and 1000 times less than the disc stars.

In addition to single stars, the spheroid and the central reservoir contain a few hundred spherical stars.

The galactic spheroid is surrounded by a galactic crown on all sides, with a radius of 700,000. There are almost no single stars in the crown, only a few spherical spheres and invisible material, the thrust of which affects the movement of the stars of the Galactic. The mass of this invisible material is at least 10 times the total mass of all galactic stars.

The mass of galaxy stars and interstellar matter is about 2 · 1011 M, and along with the invisible material - 2 · 1012 M.

What are the top 10 strategic technology trends in 2019?

IT advisory agency Gartner has announced major strategic technology trends for 2019, which companies should pay attention to. More details are available at the Gartner Symposium / IT Expo in Orlando, Florida,

Strategic technology trends selected by Gartner are made up of technologies with innovative potential. These are technologies that boast of new technologies and rapid growth rates that show a wider range of influences and use cases from the initial state, and are expected to peak in the next five years.

"Intelligent, Digital, and Mesh have been a hot topic over the past two years and will be a key growth driver in 2019," said David Cearley, vice president and fellow at Gartner. The trends on these three themes are key to driving the ongoing innovation process as part of the Continuous NEXT strategy. "

Gartner's 2019 top 10 strategic technology trends are as follows.

Autonomous Things

Autonomous things such as robots, drones, and autonomous vehicles use AI to automate human functions. Their automation goes beyond automation through a rigorous programming model and leverages AI to perform advanced actions that naturally interact with the environment and people.

"As autonomic objects expand, we will move away from independent intelligent objects and follow a human command or introduce a variety of intelligent objects that can work with multiple devices themselves," says David Sulliv. For example, if the drones are found to be ready for harvesting by surveying a large field, then the "autonomous harvesting machine" is activated. Or, the most efficient solution in the shipping market could be to use self-propelled vehicles to move packages to the target area. Vehicle-mounted robots and drones can guarantee the final delivery of parcels. "

Augmented Analytics

Augmented Analytics focuses on specific areas of augmented intelligence using machine learning to revolutionize the way in which analysis content is developed, consumed, and shared. Augmentation analysis capabilities will rapidly evolve into key functions of data preparation, data management, modern analysis, business process management, process mining and the data science platform. The automated insights gained from the incremental analysis will be applied to business activities such as HR, finance, sales, marketing, customer service, procurement and asset management departments to optimize the decisions and actions of all employees, including analysts and data scientists. Augmentation analysis automates the process of data preparation, generation of insights and visualization of insights, eliminating the need for specialized data scientists in many situations.

"This will lead to new capabilities and practices, citizen data science, that enable non-statisticians and analysts to draw predictive or normative insights from their data," said David Sulliv. The number of civilian data scientists will increase five times faster than the number of specialized data scientists. Organizations can use civic data scientists to address the labor shortages of data science and machine learning caused by the scarcity and high cost of data scientists. "

AI-Driven Development

The market is rapidly changing to a model that professional developers can operate alone using a serviceable predefined model, away from the approach that professional data scientists have had to work with application developers to build most of the AI enhancement solutions. It provides developers with development tools designed to integrate AI algorithms and model ecosystems, as well as models and AI capabilities into the solution. As AI is applied to the development process itself to automate a variety of data science, application development and testing functions, there is another level of opportunity for specialized application development. By 2022, at least 40% of new application development projects are expected to have AI co-developers in the team.

"Ultimately, a highly sophisticated, AI-driven development environment that automates both the functional and non-functional aspects of an application is a 'citizen application developer' who can create new solutions automatically using AI-driven tools, "Tools that allow non-experts to create applications without coding are not new, but we expect AI-driven systems to offer a new level of flexibility," he said.

Digital Twins

Digital Twin refers to digital versions of objects or systems that exist in the real world. Gartner expects to generate more than 20 billion connected sensors and endpoints by 2020, with potential digital bottlenecks in billions of objects. Organizations will initially apply digital twinning in a simple way. Over time, they will evolve as they acquire and visualize the right data, apply the right analysis and rules, and improve their ability to respond effectively to business goals.

"One aspect of digital twin evolution beyond IoT is the implementation of Digital Twins of an Organizations (DTOs) for their organizations," said David Sulliv, A dynamic software model that relies on operational or other data to understand how to connect to the current state, deploy resources, and realize customer value in response to change. "

Empowered Edge with Autonomy.

An edge refers to an endpoint device that is used by people or embedded around us. Edge computing tries to process traffic and processing locally to reduce traffic and latency.

Soon the edge will be dominated by IoT, and if necessary, processing will be maintained near the end of the centralized cloud server. Instead of creating a new architecture, cloud computing and edge computing will evolve into a model that supplements cloud services managed as a central service in centralized servers as well as decentralized on-premises and edge devices themselves.

Over the next five years, a special AI chip with more processing power, storage and other advanced features will be built into the various edge devices. Along with the extreme heterogeneity of these embedded IOT worlds, the long life cycle of assets such as industrial systems creates significant difficulties in management. In the long term, as 5G becomes mature, the extended edge computing environment will build stronger communications with centralized services. 5G offers lower latency per square kilometer, higher bandwidth, and the number of nodes (edge endpoints), which is the most important factor in the edge.

Immersive Experience.

Interactive platforms are changing the way people interact with the digital world. Virtual reality (VR), augmented reality (AR), and mixed reality (MR) are changing the way people perceive the digital world. This integrated change in perception and interaction model leads to a future immersive user experience.

"Over time, we will move away from discrete devices and fragmented user interface (UI) technologies to multi-channel and multi-mode experiences," said David Sulliv. "The multimode experience will connect people and the digital world, spanning hundreds of edge devices, including traditional computing devices, wearable devices, automobiles, environmental sensors and consumer electronics. But also utilize all of the advanced computer senses (heat, humidity, radar, etc.) of multimode devices. This multiple experience environment provides an ambient experience in which the space surrounding us defines "computers" rather than individual devices. In fact, the environment becomes a computer. "

Block Chain.

Blockchain is a kind of distributed ledger that will restructure the industry by building trust, providing transparency, reducing potential costs due to reduced friction between business ecosystems, reducing transaction settlement times, and improving cash flow . Today, trust is built in banks, clearing houses, governments, and other agencies that serve as central authorities, and a "single version of truth" is securely stored in their databases. This centralized trust model adds delay and frictional costs (commission, commission and time value of money) to the transaction. On the other hand, the block chain provides an alternative trust mode and eliminates the need for central authorities in arbitration transactions.

David Sully, vice president, said, "The current block chain technology and concepts are immature, not well understood, and have not been validated for business-critical and large-scale business operations. "In spite of these difficulties, the block-chain technology has tremendous potential for innovation, so CIOs and IT leaders must be actively involved in the technology within a few years. If you do not adopt it, you should begin to evaluate it. "

Many block chain initiatives today do not implement all the characteristics of a block chain, including distributed databases. These block-chain-based solutions are used as a means of achieving operational efficiency by automating business processes or digitizing records. They have the potential to improve the sharing of information between known individuals and to improve the chances of tracking physical and digital assets. However, these approaches can miss the true value of block-chain innovation and increase dependency on suppliers. Organizations that choose this option should be prepared to understand the limitations and be ready to transition to a complete block-chain solution and realize that using the existing non-block-chain technology more efficiently and appropriately can achieve the same result Should be.

Smart Spaces.

Smart space refers to a physical or digital environment in which people and technology systems are more open, connected, coordinated, and interacting in intelligent ecosystems. Many factors, including people, processes, services, and things, gather in a smart space, creating a more immersive, interactive and automated experience aimed at target users and industry scenarios.

"These trends have been converged around factors such as Smart City, digital workspace, smart home, and connected factories," said David Sulliv, vice president and general manager, As it becomes a vital part of life, the market has entered a stage where it is increasingly providing solid smart space. "

Digital Ethics and Privacy.

Digital ethics and privacy are the concerns of individuals, organizations and governments alike. People are increasingly concerned about how their personal information is used by the organization in the public and private sectors, and the opposition to organizations that do not actively address these concerns is increasing.

David Sully, vice president, said, "All discussions about privacy should be based on a wide range of topics on digital ethics and the trust of customers, members and employees. While privacy and security are the building blocks of trust, trust is more than just these elements. "Trust is the acceptance of the truth of the statement without evidence or investigation. Ultimately, the organization's position on privacy should be driven by a broader concept of ethics and trust. The transition from privacy to ethics changes the discourse on whether we are doing what we are about whether we are doing what is right.

Quantum Computing.

Quantum Computing (QC) is a type of non-conventional computing that operates in the quantum state of subatomic particles such as electrons and ions that represent information as a quantum bit (qubit) element. Parallel execution and exponential scalability of quantum computers means that traditional approaches are either too complex or to solve problems that take a long time to find solutions with traditional algorithms. Industries such as automotive, finance, insurance, pharmaceutical, military and research organizations are benefiting most from the development of quantum computing. For example, in the pharmaceutical industry, quantum computing can be used to model molecular interactions at the atomic level to accelerate the time to market of new cancer treatment drugs. Or quantum computing can be used to more accurately predict protein interactions leading to new pharma- ceutical methodologies.

"CIOs and IT leaders must begin planning for the adoption of quantum computing by increasing understanding and understanding how they can be applied to real business problems," said David Sulliv. You need to learn when technology is still in the emerging stages. "Quantum computing needs to figure out the real problems with potential and consider the potential impact on security," he said. "But you should not trust exaggerated advertising to innovate things in the next few years. Most organizations will need to learn and monitor quantum computing by 2022 and use it by 2023 or 2025. "

Nature Selection, 2019 Top 10 Scientific Issues We Need to Know

The international science journal Nature has selected 10 science issues to be highlighted in 2019. Some of them are science projects that have been tried for the first time in human history. The most important keyword of large-scale science and technology that will be realized in various fields in the New Year is 'environment'. What kind of technology will scientists challenge?

1. Antarctic iceberg collapse study and 1.5 million years old ice core search.

What will be the most important science issue in 2019? Nature is ranked first in the study of the collapse of the Antarctic ice sheet due to climate change, a project of the National Science Foundation and the UK Natural Environment Research Society, which is launched in January.

The project is to predict how much time left for the actual collapse of the Thwaites Glacier, which belongs to the five glaciers of Antarctica. It is the largest joint research in Antarctica over 70 years.

The size of the Tweetwater glacier is 1.5 times the area of Korea. These gigantic glaciers have recently melted rapidly from below and are unstable. The team will estimate the melting rate of glaciers over the next five years and calculate when the glaciers will collapse. In this work, an autonomous navigable unmanned submersible is used. The submersible observes the movement of the glacier below the surface of the water and seals with sensors attached to the forehead are used to identify the marine ecosystem near the glacier.

Meanwhile, by the end of 2019, European scientists in the South Pole will begin a drilling project to find the "ice core" for 1.5 million years. At Little Dome C, a certain point in Antarctica, the glaciers will be pierced with long sticks and samples will be collected. This is because there is a key in the Antarctic ice to figure out the atmosphere of the ancient earth. It is the air that was contained when the ice was created.

If you put your Antarctic ice in water and tilt your ears, you can hear the rumbling sound like in a carbonated drink. The air bubbles in the ice are popping. Very old ice has been studied to contain less than 20% of the total air. The more ice is made recently, the more air there is.

The air in the ice has been mixed in the process of snow accumulation and compression in the Antarctic for a long time. The ice is piled up every year, so the lower the air is, the older it is. By studying what constitutes this old air, you can learn more about the environment and climate at that time. So scientists are trying to drill deep holes in the ice of Antarctica to save ice. This long cylindrical shape of ice is the 'ice core'. Let's wait for scientists to look at the 'old earth' to find a windswept on cold ice.

2. Delay global warming ... The first artificial experiment ever.

There is also a plan to solve the problem of global warming with the power of science and technology. For the first time in human history, the 'Solar Geoengineering' project that artificially slows global warming is it. In an experiment called SCoPEx (Stratospheric Controlled Perturbation Experiment), it is a way to cool the earth by artificially reducing sunlight coming into the surface by spraying sunlight reflecting material into the stratosphere. It is a technology that I could see in the movie 'Geostrum' (2017).

Researchers at Harvard University's Department of Applied Physics and Atmospheric Sciences are working on the experiment. According to the researchers, 0.1 to 1 kg of calcium carbonate, which reflects the sunlight well using a hot air balloon, is sprayed over 20 km in the stratosphere. Then we look at how much sunlight has decreased and how the temperature has changed, and how the calcium carbonate microparticles have affected the chemicals that make up the atmosphere to see if it can be cooled. In 1991, when the Pinatubo volcano erupted in the Philippines, 20 million tons of sulfate particles were generated in the stratosphere, and the objective was to artificially reproduce the earth's cooling of about 0.5 degrees Celsius.

Some skeptics, however, are concerned that "calcium carbonate, a kind of chalk powder, can create unexpected results in the sky and can make a bungling effort to reduce greenhouse gas emissions."

3. Space signal capture? Operation of the world's largest radio telescope.

China's Spherical Telescope (FAST) 'Tian'an (Snow of the sky)', which has been in operation since September 25, 2016, will be in operation from September this year and will be opened to scientists in earnest. Tianyen is the world's largest radio telescope, 500m in diameter and 30 square meters in size, with an area of 250,000 square meters.

Tianyen, built with 1.2 billion yuan (about 198.5 billion won), has been monitoring the operation of more than 50 new pulsars (neutron stars). When the supernova explodes in the process of the star 's evolution, the neutron star rotates at super - fast speed as the star' s core contracts. At that stage, it emits a short, regular pulse signal. There are so many pulsers in the galaxy, but the signal is so weak that only about 2,700 pulsars have been identified so far.

World scientists will use Tianyan to observe the faint signals from the 'Fast Radio Burst' (FRB) and interstellar matter. A high-speed radio explosion is a "buzzing" noise from the universe, propagated only for a short period of time, on the order of milliseconds (ms • 1 ms is a thousandth of a second), intermittently observed only through radio telescopes. A total of 18 high-speed radio blasts were detected for 10 years after the first detection in 2007, but they do not know exactly where they occurred. Therefore, it is called 'the sound of aliens', and remains a mystery of the astronomical system. World scientists will unleash all the secrets of the roar through Tianyan.

4. Japan to build international linear particle collider.

The year 2019 is also an important year for deciding whether or not to attract successors to the LHC, which finds Higgs particles. It is the 'International Linear Collider (ILC)' construction plan. After detecting the Higgs particles using the LHC at the European Particle Physics Research Institute (CERN) in 2012, the world's particle physicists have been discussing the construction of next-generation particle accelerators that can generate massive Higgs particles and study their properties in more detail.

So, Japanese physicists announced that they will organize the construction of ILC, which is 31km in length, in order to operate in 2030. Japan is the only country that has shown interest in attracting ILCs. Linear accelerators can more precisely implement Higgs particles by accelerating and colliding atomic electrons and positrons in long straight lines. As the construction of the LHC began to be discussed from the 1980s, Japanese physicists have also been attracting attention for more than a decade since launching the next generation accelerator plan and basic design.

An astronomical cost of about $ 10 billion is needed to build an ILC. The Japanese government did not support the ILC construction project because of the huge cost. For this reason, Japanese physicists will announce the official position on March 7 to decide whether to keep or withdraw the ILC construction policy. There is a great interest in world particle physics academics as to what kind of results Japan will produce.

5. Gene editing controversy continues.

In late November, Hugen Kuu, professor at the Southern China University of Science and Technology, revealed that he created a baby who edited the gene with CRISPR-Cas9 technology. It corrects the gene of the artificially fertilized embryo and causes a twin girl who is resistant to human immunodeficiency virus (HIV) to cause AIDS. It is the first 'genetically modified baby' in human history that has prevented AIDS in advance. Scientists and technologists at the time pointed out that they ignored the ethics of life research, and expressed concern that existing genetic editing research might even shrink.

Nature has predicted that the controversy surrounding the unexpectedly open "Pandora's Box" will continue in the new year. In the reality that most countries in the world do not allow genetic editing of human embryos, Hezenko's research was a shocking event. World geneticists plan to work on assessing potential side effects, such as whether Hugenkoei has actually edited twin girls' DNA or edited the DNA if it has been edited, and whether it is more susceptible to new virus infections . The international community has a high voice to establish an ethical framework for bioscience research to control genetic engineering experiments.

6. Implementation of 'Plan S' to open in the form of open access.

The implementation of Plan S, an open access movement, is also a science-related issue that attracts attention in the new year. Plan S is a project that aims to open academic research results (papers) from 2020 as free open access that anyone can access, not closed journals, as long as there are no special reasons. The first veteran science policy officer in Europe, Robert-Jans Sumitz, launched Plan S to open more scientific papers to anyone.

There is a strong interest in the open access movement around the world. The National Institutes of Health has publicly stated that it should be made public for anyone with research funded by the national tax. Some leading American universities, such as MIT and Harvard University, have announced plans to publish their findings on their institution's Web site. The Bill & Melinda Gates Foundation in the United States and the Wellcome Trust in the United Kingdom will join Plan S to support research funding in various fields.

"We need to change the business model in order to accept Plan S," said Nature. I hope that the open-access movement, which has not been settled yet, will be settled in order to solve the knowledge gap and strengthen the research competitiveness of academic researchers.

7. Identify the Origin of Humanity! Research is pouring.

The movement to uncover the origins of ancient humanity (Hominin) is also noticeable. In 2003, archaeologists unearthed human-like "Hobbit" species on Flores Island, Indonesia. Since then, more ancient human fossils have been discovered in China, and research on the origin of humanity has been proceeding rapidly.

Nature expects fossils that reveal the origin of the New Year's hummi species to be found much more in Southeast Asian islands. In particular, I expected to see a lot of clues from Hominin, who first lived in Luzon Island, Philippines. Luzon Island is a region that has received attention from academia since the discovery of Hobbit species on Flores Island. If the various fossils were excavated in Luzon Island, Nature would see more facts about humans who first lived on the island, and the secrets to why the size of humans in Florida could be shrunken.

8. The secrets of the weed ... Basic and applied research

Research on cannabis is also expected to become visible. In particular, many Canadian researchers are involved in studies covering the growth of cannabis, its effects on the body, and its effects on the human body.

Because the Canadian government in 2018 legalized cannabis for the second time in the world after Uruguay, the state and federal governments provided huge funding for research on marijuana so that they would not be behind each other.

By the end of 2019, Canada's first marijuana research center will be built at Guelph University in Canada. It is expected to study everything from cannabis genetics to health benefits. The science and technology community expects to see a variety of research results on cannabis for the first time this year.

9. Full revision of 'Laboratory Biosafety Manual' .

By mid-2019, a major revision of the World Health Organization's "Laboratory Biosafety Manual" will be finalized. This manual is a universally accepted guideline that contains treatment standards and emergency response laws that safely treat pathogens to protect humans from infectious, high-risk pathogens such as Ebola. At the same time, it also serves as a reference resource for pathogen handling agencies and researchers, thereby enhancing convenience.

The 'Laboratory Biosafety Manual' was first published in 2004. It is a full-scale revision to be implemented within the next 15 years. WHO is revising its manuals to enhance laboratory safety-related assessment, management improvement, and researcher training.

10. Chinese and European science and technology... R & D investment.

Investment in science and technology is expected to continue into the new year. Especially, China is expected to be a terrifying 'runaway'. By the end of 2019, the world will be able to push the United States to become the world's largest research and development (R & D) investment country by announcing the 2018 accounting report, which shows the investment performance of science and technology.

China's science investment has been growing rapidly since 2003. It is attracting attention from the world in terms of R & D scale and quality. China has launched Changer 4, which landed on the back of the New Year's early moon, on December 8 last year, and succeeded in raising the plasma temperature, which is essential for nuclear fusion reactor construction, by 100 million.

Europe also invests $ 110 billion (123.7 trillion won) in new year R & D. The European Union is discussing ways to fund the research funding program "Horizon Europe" from 2021 to 2027. It also suggests ways to create jobs. The European Commission's proposal since 2013 has a bold commitment to invest in the future of Europe so that even the smallest amount of money can be returned to the people of Europe.
