The North Star was the star closest to the North Celestial Pole. It was located in the constellation Ursa Minor and was also known as Gouchen Yi. Its position in the night sky was relatively stable, almost facing the earth's axis. Polaris's brightness was relatively dim, and its apparent magnitude fluctuated around 1.98, visible to the naked eye. It was the polar star of the northern hemisphere, almost above the North Pole. The position of the North Star could be used to determine the direction and latitude, so it played an important role in navigation. The North Star also symbolized firmness and loyalty. Polaris was about 445.3 light-years away and was one of the closest Cepheid variable stars. The position of the North Star was relatively stable, but every 25,800 years, the direction of the Earth's axis would change, allowing other stars to become the North Star. In short, Polaris was a unique and important star in the night sky.
Yes, there are. Some books might explore the concept of plastics in a fictional context, like how plastics could be used in a futuristic society in a novel. For example, a science - fiction novel could depict a world where plastics have unique properties or play a crucial role in the plot.

The Polaris mech in Titanfall 2 was a high-mobility light Titan. It had the following advantages: the charged electromagnetic railgun had the highest single target damage of all Titans, and could consume almost one bar of the opponent's health with one shot; it could aim at the target and narrow the field of view for long-range sniping; the damage of the cluster missiles was also very high, suitable for clearing large groups of miscellaneous soldiers and enemies in the room; it was highly mobile, suitable for kiting and long-range attacks. There was no mention of the Northstar mecha's weakness in the information given.
Well, without further information, it's difficult to say precisely. It might cover things like the production levels of plastics in the present day, any recent breakthroughs in plastic recycling, or perhaps the use of plastics in different sectors currently.
Again, with so little information, it could be anyone. It might involve plastic manufacturers, environmentalists, or even consumers who are affected by the plastics situation today.
A novel simplified scheme for plastics identification might involve using unique markers or tags on the plastics, or perhaps a special type of scanner or sensor that can quickly determine the plastic type with high accuracy. This could simplify the sorting and recycling processes.
You can start by looking in your local library. Check the science fiction or environmental sections as they are more likely to have books related to plastics in a fictional context. You could also search on online bookstores like Amazon. Just type in 'books on plastics novel' and see what comes up.
The main idea might be about the complex relationship we have with plastics. We love plastics for their convenience, but they are toxic to the environment. They are everywhere in our daily lives, but they also cause pollution and harm to wildlife and ecosystems.
