General Awareness of Science And Technology General Questions And Answers In 2021

This section contains current affairs on general awareness of science and technology general questions and answers in 2021. Read them through.

What is the most popular topic of 2021 that brought revolution? 

In 2021, there was a lot of discussion on the use of artificial intelligence and its impact on society. There were concerns over how much control AI would have over humans and their livelihoods, but many experts argued that the benefits of using AI outweighed the risks.

What advancements were made in quantum computing in 2021?

The development of quantum computing continued to make waves in 2021, with more and more businesses investing in the technology. Quantum computing was seen as a way to boost efficiency and security, and many believed that it would soon become the norm for data processing.

Which is the first country to land on the far side of the moon?

China became the first country to land a probe on the far side of the moon.

Did climate change see any improvements in 2021?

Climate change was a topic that continued to dominate headlines in 2021 as scientists warned about the dangers of global warming. There was also much debate over how best to tackle climate change, with many calling for more renewable energy sources such as wind farms and hydroelectric dams while others argued that nuclear energy could provide a solution.

What did scientists of MIT make in 2021?

In the field of medicine, there were some breakthroughs in 2021 that could have a positive impact on human health. For instance, scientists at MIT created an artificial pancreas with insulin-producing cells derived from stem cells; this means type one diabetes sufferers will no longer need to take regular injections or insulin tablets every day.

What major advancements took place in robotics in 2021?

In 2021, there were also many advancements in the field of robotics. One example is AI-powered robots that can perform tasks such as cleaning up spills and performing surgery without any human intervention or input from doctors or nurses; these kinds of technologies will likely be the future for healthcare facilities around the world!

General Awareness of Science And Technology General Questions And Answers In 2020

This section contains current affairs on general awareness of science and technology general questions and answers in 2020. Read them through.

What is the difference between a black hole and a neutron star?

A black hole is an object in space that has such a strong gravitational field that nothing, not even light, can escape from it. A neutron star is the collapsed core of a large star. It is incredibly dense, with a mass equal to that of about two suns.

What is a solar sail made from?

Solar sails are made from ultra-thin, reflective materials such as Mylar or aluminized plastic that are stretched out over a lightweight frame. The sail then uses the momentum of photons (light particles) to propel itself through space.

What is the energy source behind solar flares?

The Sun’s magnetic field lines can become twisted and tangled, causing energy to build up. When the stress becomes too great, a solar flare erupts.

What is dark matter?

Dark matter is an unidentified type of matter that makes up about 27% of the universe. It is thought to be composed of exotic particles that neither emit nor absorb light, hence its name.

What are some of the challenges facing space-based solar power?

One challenge is finding a way to transmit the energy from space back down to Earth. Another challenge is how much this will cost. It could be very expensive to put up and maintain such a large installation in orbit around our planet.
