Technology Startups
Technology is the application of conceptual knowledge to achieve practical goals, especially in a reproducible way. The word ''technology'' can also mean the products resulting from such efforts, including both tangible tools such as utensils or machines, and intangible ones such as software. Technology plays a critical role in science, engineering, and everyday life. Technological advancements have led to significant changes in society. The earliest known technology is the stone tool, used during prehistory, followed by the control of fire—which in turn contributed to the growth of the human brain and the development of language during the Ice Age, according to the cooking hypothesis. The invention of the wheel in the Bronze Age allowed greater travel and the creation of more complex machines. More recent technological inventions, including the printing press, telephone, and the Internet, have lowered barriers to communication and ushered in the knowledge economy. Whil ...

Human Brain
The human brain is the central organ (anatomy), organ of the nervous system, and with the spinal cord, comprises the central nervous system. It consists of the cerebrum, the brainstem and the cerebellum. The brain controls most of the activities of the human body, body, processing, integrating, and coordinating the information it receives from the sensory nervous system. The brain integrates sensory information and coordinates instructions sent to the rest of the body. The cerebrum, the largest part of the human brain, consists of two cerebral hemispheres. Each hemisphere has an inner core composed of white matter, and an outer surface – the cerebral cortex – composed of grey matter. The cortex has an outer layer, the neocortex, and an inner allocortex. The neocortex is made up of six Cerebral cortex#Layers of neocortex, neuronal layers, while the allocortex has three or four. Each hemisphere is divided into four lobes of the brain, lobes – the frontal lobe, frontal, pa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Technological Unemployment
The term technological unemployment is used to describe the loss of jobs caused by technological change. It is a key type of structural unemployment. Technological change typically includes the introduction of labour-saving "mechanical-muscle" machines or more efficient "mechanical-mind" processes (automation), and humans' role in these processes are minimized. Just as horses were gradually made obsolete as transport by the automobile and as labourer by the tractor, humans' jobs have also been affected throughout modern history. Historical examples include Textile manufacture during the Industrial Revolution, artisan weavers reduced to poverty after the introduction of Power loom, mechanized looms. Thousands of man-years of work was performed in a matter of hours by the bombe codebreaking machine during World War II. A contemporary example of technological unemployment is the displacement of retail cashiers by Self-checkout, self-service tills and cashierless stores. That techn ...

Resource Depletion
Resource depletion occurs when a natural resource is consumed faster than it can be replenished. The value of a resource depends on its availability in nature and the cost of extracting it. By the law of supply and demand, the Scarcity, scarcer the resource the more valuable it becomes. There are several types of resource depletion, including but not limited to: wetland and ecosystem degradation, soil erosion, aquifer depletion, and overfishing. The depletion of wildlife populations is called ''defaunation''. It is a matter of research and debate how humanity will be impacted and what the future will look like if resource consumption continues at the current rate, and when specific resources will be completely exhausted. History of resource depletion The depletion of resources has been an issue since the beginning of the 19th century amidst the Industrial Revolution, First Industrial Revolution. The extraction of both renewable and non-renewable resources increased drasticall ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pollution
Pollution is the introduction of contaminants into the natural environment that cause harm. Pollution can take the form of any substance (solid, liquid, or gas) or energy (such as radioactivity, heat, sound, or light). Pollutants, the components of pollution, can be either foreign substances/energies or naturally occurring contaminants. Although environmental pollution can be caused by natural events, the word pollution generally implies that the contaminants Human impact on the environment, have a human source, such as manufacturing, Extractivism, extractive industries, poor waste management, transportation or Agricultural pollution, agriculture. Pollution is often classed as point source pollution, point source (coming from a highly concentrated specific site, such as a factory, Environmental effects of mining, mine, construction site), or nonpoint source pollution (coming from a widespread distributed sources, such as microplastics or agricultural runoff). Many sources of po ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Prosperity
Prosperity is the flourishing, thriving, good fortune and successful social status. Prosperity often produces profuse wealth including other factors which can be profusely wealthy in all degrees, such as happiness and health. Competing notions of prosperity Economic notions of prosperity often compete or interact negatively with health, happiness, or spiritual notions of prosperity. For example, longer hours of work might result in an increase in certain measures of economic prosperity, but at the expense of driving people away from their preferences for shorter work hours. In Buddhism, prosperity is viewed with an emphasis on Collectivism and individualism, collectivism and spirituality. This perspective can be at odds with capitalistic notions of prosperity, due to the latter's association with greed. Data from social surveys show that an increase in income does not result in a lasting increase in happiness; one proposed explanation to this is due to hedonic adaptation and soc ...

Economic Development
In economics, economic development (or economic and social development) is the process by which the economic well-being and quality of life of a nation, region, local community, or an individual are improved according to targeted goals and objectives. The term has been used frequently in the 20th and 21st centuries, but the concept has existed in the West for far longer. "Modernization", "Westernization", and especially "industrialization" are other terms often used while discussing economic development. Historically, economic development policies focused on industrialization and infrastructure; since the 1960s, it has increasingly focused on poverty reduction. Whereas economic development is a Public policy, policy intervention aiming to improve the well-being of people, economic growth is a phenomenon of market productivity and increases in GDP; economist Amartya Sen describes economic growth as but "one aspect of the process of economic development".
