What is Sci-fi?

A member of the Reading Club casually remarked about sci-fi and elaborated, “Science fiction is abbreviated as sci-fi or at times, SF, and this genre yokes the two contradictory disciplines together. As we know, fiction is fictitious and science stands for rationality. But some novelists have succeeded in bringing them together. This popular genre transports readers to a future hinging on the concepts such as time travel, space exploration, aliens, parallel universes, and so on, and, to our amazement, some of them are turning out to be real now.” His explanation aroused our interest in reading and discussing H.G. Wells’ ‘The Time Machine’ in the following meeting.

Four of us participated in a group sharing. Each one focussed on an aspect, and the following are some of our key ideas.

Popularity of sci-fi

Although the origin of science fiction can be traced back to the previous centuries, its golden age is the 1940s and 1950s. These were the decades of significant scientific discoveries, namely space exploration and nuclear energy, which the novelists subsumed in their imagination. As is the case with all genres of fiction, sci-fi too has all the elements such as setting, characters. plot development, theme, climax, and point of view. What makes it unique is all these elements are heavily dependent on scientific facts, theories, and principles hinged on an imaginative story.

Sci-fi movies

Sci-fi movies also have become very popular in the last few decades. It is rare to come across anyone who has not watched or heard of films such as ‘Avatar’, ‘Jurassic Park’, ‘Star Wars’, ‘Alien’, ‘The Matrix’, and so on. They also share the same features as the novels, and, in fact, most of them are based on them.

As many as 23 novels and stories of H.G. Wells alone have been made into films, including The Time Machine. These are immensely popular with moviegoers as they are full of action, adventure, and twists and turns, gripping them.

H.G. Wells

H.G. Wells, the “Father of Science Fiction”, was born in Kent, England, in 1866 and died in 1946. He was the son of domestic helpers, and because of his inexhaustible love for reading, he rose to become one of the most influential British authors. He was a prolific writer, equally known for fiction and non-fiction works, which not many have managed to achieve. He wrote more than 50 novels, dozens of short stories, and many non-fiction, including in the areas of politics, history, and social commentary. But he is more known for his sci-fi novels.

The Time Machine

The novel is about a time traveller who builds a machine and travels to a distant future – the year 8,02,700 A.D., and narrates his experiences at ‘the world of the remote future’ to a group of his friends. It is worth sharing the traveller’s initial encounter with the people/creatures living there:

“He (Eloi) was a slight creature-perhaps four feet high… they looked so frail that I could fancy myself flinging the whole dozens of them about like nine-pins… one of them asked me a question that showed him to be on the intellectual level of one of our five-year-old children…”

“A flow of disappointment rushed across my mind. For a moment I felt that I had built the Time Machine in vain.”

The time traveller elaborately describes the two races of humanity occupying the landscape-child-like Eloi and monstrous Morlocks. Eloi are small, unintelligent, weak but kind and happy people but Morlocks are the labourers forced to live underground working for the overlanders. The traveller has varied experiences with them and finally manages to locate his stolen machine and escapes from the dark world. What initially appears like a utopia turns out to be a dystopia to him.

 The story ends with an unnamed narrator informing us about another trip of the time traveller to reach the end of Earth’s existence and bring back proof of his adventure. But three years have elapsed, and the narrator If wonders whether the traveller is still wandering in time or has perished.

‘The Time Machine’, Wells’ first novel, brought him immediate fame, and till today, has been regarded as a masterpiece of science fiction.

U.K. LAUNCHES NEW COURSE TO TEACH STUDENTS HOW TO SAVE THE PLANET.

The U.K. will offer a new GCSE (General Certificate for Secondary Education) from September 2025 that will “offer young people a chance to develop a deeper knowledge and understanding of this amazing planet, its environment and how to conserve it,” said education secretary Nadhim Zahawi.

The qualification will allow students to learn about organisms and their environments, as well as environmental and sustainability issues. Students will also develop skills for future careers in conservation, “from understanding how to conserve local wildlife to conducting the fieldwork needed to identify species”

Students learn about environmental issues already; this course will teach them about the history and evolution of species and the impact of life on natural environments.

Teen conservationist and wildlife writer Kabir Kaul, 15, said the course “will give my generation the knowledge and practical skills they need to value and protect the environment around them”.

What are Twisters?

A thick, dark cloud forms in the sky. Warm air from near the earth rises rapidly towards the cloud. At the bottom of the cloud, the air starts spinning. This wind spins and twists and drops down into the shape of a long tube, or funnel. This wind is called a tornado, or twister.

The funnel may touch the earth’s surface. When a tornado touches ground, it can be dangerous. It can pick up heavy machinery and toss it far. The winds of a tornado rip roofs from houses and uproot large trees.

Tornadoes can happen in many parts of the world. But most tornadoes happen over the central U.S.A. People have recorded whirlwinds about 480 kilometres per hour there.

A tornado is a whirling wind that reaches down from the clouds and touches the ground. But dust devils and sand pillars are whirling winds that go from the ground up into the sky. They are much smaller than a tornado.

What surrounds the Earth?

 

 

Long ago, people believed the sky was a roof that stretched over the earth. Today, we know that a thick layer of air surrounds the earth like the skin on an orange. But unlike an orange skin, the air moves around the earth, and it reaches far above the earth’s surface. This moving cover of air is a mixture of gases called the earth’s atmosphere.

Air covers the earth everywhere. The pull of gravity holds it there. Near the earth, the air is thick, or heavy. Further away from the earth, the air becomes thinner. Furthest away from the earth’s surface, the air thins and disappears altogether. Where this happens is where space begins!

Who studies the waters?

Many scientists study the ocean, looking into the secrets of the sea. They study how the ocean moves and how it affects the atmosphere. They study the living things in the sea and the shape of the ocean floor.

Scientists who study the ocean are called oceanographers. Sometimes they work aboard ships. Some wear diving suits and air tanks to explore underwater. Others use small submarines. They use underwater cameras to take pictures of the ocean’s floor and the plants and animals that live in the ocean.

Sometimes they use robots to bring up samples of the mud and sand for study. Some scientists study the direction and strength of waves, tides, and currents.

Oceanographers called marine biologists study the plants, fish, and animals that live in the ocean, lakes, and rivers. They keep track of their health and the way they grow.

Oceanographers called seismologists study earthquakes that happen on the ocean floor. One cause of earthquakes is volcano eruptions, so seismologists often keep track of volcanic activity.

What is underground water called?

Water from Underground

Not all of the earth’s water is in lakes, ponds, rivers, and oceans. A lot of it is beneath your feet – down in the ground.

Rain falls. Snow melts. Much of the water seeps into the ground. It passes through holes and cracks in the soil until it reaches solid rock. The water can’t trickle any further down, so it spreads out, filling every nook and cranny underground.

The top of this underground water is called the water table. When there is a lot of rain, the water soon fills all the open spaces underground. Then the water table gets higher.

In some places, the water table comes all the way to the top of the ground.

Then, water bubbles out and makes a natural fountain called a spring. Sometimes a spring is the start of a river.

Underground water is usually cool and clean and good to drink. People often dig wells to get this water. There is some underground water almost everywhere in the world – even in deserts. But in a desert, the water is often very, very far down underground.
