In the world today, people cannot live without technologies such as televisions, mobile phones, computers and others. These technologies have slowly taken an essential part in people’s day-to-day lives and being without them would be unimaginable for some of us. To understand technology, one must know what it provides in terms of advantages, but also disadvantages
Inventions affects our society significantly. It has become an integral part in our life by bringing so much benefits to us. Inventions improves the efficiency in education, medicine, transportation, entertainment and more. When mentioning of how inventions impacts our community, people will think of its positive influence. However, according to Newton’s third law of motion, “For every action, there is an opposite reaction”. Indeed, inventions is beneficial to us, however at the same time it brings negative consequences. Although the rise of new inventions has improved our daily lives by bringing many conveniences, it increases the rate of obesity and the isolation in our society.
New inventions makes people become more isolated. It significantly impacts our social interaction. One might think that social network brings people together. Although many inventions have helped us and made our lives easier they have also caused some problems. With the invention of the car came problems such as air pollution. Cities are becoming more and more congested with people using their cars even for short distances. The government is trying to make this better by making. Cars pass an emission control test. Another problem with cars is that hundreds of people die or get seriously injured each year.
Thomas Parker built the first practical production electric car in London in 1884, using his own specially designed high-capacity rechargeable batteries. The Flocken Elektrowagen of 1888 was designed by German inventor Andreas Flocken . Electric cars were among the preferred methods for automobile propulsion in the late 19th century and early 20th century, providing a level of comfort and ease of operation that could not be achieved by the gasoline cars of the time. The electric vehicle stock peaked at approximately 30,000 vehicles at the turn of the 20th century.
What is an Electric Car?
The electric car is a vehicle that uses electric power and there are many applications to design and one of these applications is replacing the original engine of the car and put an electric motor position is the easiest way to switch from oil to electricity while maintaining the other components of the car and is provided with the power required by batteries storage power. The electric vehicle differs from the electric vehicle as a private car for persons, while the vehicle or electric vehicle is for industrial use or transport of persons in the context of public transport.
Electric vehicles or EVs, are vehicles that are powered by an electric motor instead of an internal combustion engine (Frequently). EVs use electricity as the “fuel” instead of gasoline or some other combustible fuel. The power for the vehicle is stored in many large batteries in the bottom of the car, then from there the power goes to a power regulator where it is changed from DC power to AC power. The engine only has one moving part, which send the power directly to the wheels. Therefore it does all the primary functions of a gas engine with no emissions. The electric car (EV) is a relatively new concept in the world of the automotive industry. Although some companies have based their entire model of cars around being proactive and using electricity, some also offer hybrid vehicles that work off both electricity and gas. An electric car such as Nissan Leaf, Ford Focus Electric or Tesla Model S, Chevrolet Volt is a great way for you to not only save money, but also help contribute towards a healthy and stable environment. Cars produce a lot of carbon emissions that are ejected into our natural atmosphere, leaving us vulnerable to things like pollution and greenhouse gases. In order to help positively the environment we live in, an electric car is a great step forward. By buying an electric car, you can also receive government subsidies for being environmentally conscious. Although you may end up paying more for your vehicle, the positives greatly overshadow the negatives.
Advantages of an Electric Car.
1-An electric car is a great way for people , as a consumer, to save a lot of money on gas. However, there are so many different reasons why people must invest in an electric car in the modern day of technology.
2-the Gas isn’t Require: Electric cars are entirely charged by the electricity you provide, meaning you don’t need to buy any gas ever again.
2. Savings: These cars are not expensive and can be fuelled for very cheap prices, and many new cars will offer great incentives for people to get money back from the government for going green. Electric cars can also be a great way to save money.
3. No Emissions: Electric cars are friendly as they run on electrically powered engines. It does not emit toxic gases or smoke in the environment as it runs on clean energy source. They are even better than hybrid cars as hybrids running on gas produce emissions
4. Popularity: EV’s are growing in popularity. With popularity comes all new types of cars being put on the market that are each unique, providing you with a wealth of choices moving forward.
5. Safe to Drive: Electric cars undergo same fitness and testing procedures test as other fuel powered cars. In case an accident occurs, one can expect airbags to open up and electricity supply to cut from the battery. This can prevent the driver and other passengers in the car from serious injuries.
6. Cost Effective: Earlier, owning an electric car would cost a bomb. But with more technological advancements, both cost and maintenance have gone down. The mass production of batteries and available tax incentives have further brought down the cost, thus, making it much more cost-effective.
7. Low Maintenance: Electric cars runs on electrically powered engines and hence there is no need to lubricate the engines. Other expensive engine work is a thing of past. Therefore, the maintenance cost of these cars has come down. You don’t need to send it to service station often as you do a normal gasoline powered car.
8. Reduced Noise and Pollution: Electric cars put curb on noise pollution as they are much quieter. Electric motors are capable of providing smooth drive with higher acceleration over longer distances.
Robotics is a part of Engineering and Science. It has to do with the creation and building of robots, as well as computer programming. It is interdisciplinary, using mechanical, electrical and other kinds of engineering. Robots are sometimes used to do things that humans cannot, like finding and destroying bombs, or going places that are too hot, small, dangerous or distant for humans. Some robots look like humans, but most just look like machines. In other word we can say it’s a machine that resembles a living creature in being capable of moving independently (as by walking or rolling on wheels) and performing complex actions (such as grasping and moving objects)
Robotics is the branch of mechanical engineering, electrical engineering and computer science engineering that deals with the pattern, construction, operation, and application of robots, as well as computer systems for their control, sensory feedback, and information processing. robotics or the artificial intelligence are used in manufacturing , in the search , the rescue missions and in the military , They are used in the factories across the world and the people have been increasingly losing their jobs as the robots become more efficient and precise than the humans.

6-The robots are not intelligent or sentient , They can never improve the results of their jobs outside of their predefined programming , They do not think , They do not have emotions or conscience , This limits how the robots can help & interact with people.
Volvo is testing driverless Lorries to work underground and Google has autonomous cars on the road – but what does it mean for the future of motoring?
Self-driving vehicles are cars or trucks in which human drivers are never required to take control to safely operate the vehicle. Also known as autonomous or “driverless” cars, they combine sensors and software to control, navigate, and drive the vehicle.
How they work?
Various self-driving technologies have been developed by Google, Uber, Tesla, Nissan, and other major automakers, researchers, and technology companies. While design details vary, most self-driving systems create and maintain an internal map of their surroundings, based on a wide array of sensors, like radar. Uber’s self-driving prototypes use sixty-four laser beams, along with other sensors, to construct their internal map; Google’s prototypes have, at various stages, used lasers, radar, high-powered cameras, and sonar.
The costs and benefits of self-driving cars are still largely hypothetical. More information is needed to fully assess how they’ll impact drivers, the economy, equity, and environmental and public health.
1-Safety is an overarching concern. Many thousands of people die in motor vehicle crashes every year in the United States self-driving vehicles could, hypothetically, reduce that number—software could be prove to be less error-prone than humans—but cyber security is still a chief concern.
2-Equity is another major consideration. Self-driving technology could help mobilize individuals who are unable to drive themselves, such as the elderly or disabled. But the widespread adoption of autonomous vehicles could also displace millions of Americans employed as drivers, negatively impact public transportation funding, and perpetuate the current transportation system’s injustices.
3-Environmental impacts are a serious concern, and a major uncertainty. Accessible, affordable, and convenient self-driving cars could increase the total number of miles driven each year. If those vehicles are powered by gasoline, then transportation-related climate emissions could skyrocket. If, however, the vehicles are electrified—and paired with a clean electricity grid—then transportation emissions could drop, perhaps significantly.
Hyper loop is essentially a train system that Musk calls “a cross between a Concorde, a railgun, and an air hockey table”. It’s based on the very high-speed transit (VHST) system proposed in 1972, which combines a magnetic levitation train and a low pressure transit tube. It evolves some of the original ideas of VHST, but it still uses tunnels and pods or capsules to move from place to place.
Musk has likened it to a vacuum tube system in a building used to move documents from place to place.
What speeds have been proposed?
Hyper loop is being proposed as an alternative to short distance air travel, where the system will be much faster than existing rail networks and much cleaner that flight. Hyper loop isn’t about going as fast as possible, because you’ll have to deal with high G forces when it came to turns, which isn’t ideal for passenger travel. Speeds of over 700mph are suggested for journeys.
But there are practical implications that have to be considered on a short stop-start journey, such as the acceleration and deceleration sensation that passengers would go through.
Innovations in the world of science means technology is growing day-by-day. It contributes to every step of our daily lives. Once technology introduces a new invention, scientists and developers then seek to implement new upgrades to further improve the invention, making our lives even more technologically advanced. If there is one thing in particular that is creating growth at too rapidly of a rate, it is innovation. This individual factor has made up its specific manner to develop, and there’s not a chance of ceasing it. Especially, when we don’t have to stop it. Truth be told, innovation has made our life less demanding. But, has it really? Newton’s Law says something along the lines of, “Everything has an identical and opposite reaction.” No doubt, every new invention makes our life become easier, but the question is, if all those new upgrades are helpful to use the new invention? There are some merits and demerits to each upgrade. This article discusses the benefits of new inventions and innovations of the latest technology. Finally, as most technological discoveries aim to reduce human effort, it would imply that more work is done by machines. This equates to less work for people: the human is becoming ever so obsolete by the day, as processes become automated and jobs are made redundant.
