The reason why owls look so cute is due to their big eyes. But owl’s eyes are very different from human’s. We all know that human’s eyes are a sphere, but owl’s eyes are cylinder. Because the eyes are cylindrical, they can’t rotate freely in the orbit. If owls want to observe the surrounding situation, they need to rotate the whole head. Their flexible neck can rotate 270 degrees!

Owls have large eyes, so light can easily enter their eyes. In addition, they have rich rod cells and special eye structure, which makes owls can see things at night. But although their retinas contain a lot of rod cells, they don’t have cone cells, which makes them unable to distinguish the color of things. No matter how good the owl’s eyesight is, it can’t get rid of the title of color blindness.

Sailboat is a ship that uses wind to advance. It is an ancient water transportation tool after boat and raft. It has a history of more than 5000 years. According to the number of masts, it can be divided into sloop, ketch and multi mast sailboats; according to the ship type, it can be divided into flat bottomed sailboats and pointed bottomed sailboats; according to the bow type, it can be divided into wide head sailboats, narrow head sailboats and pointed head sailboats.

According to the common people’s idea, downwind driving should be the most normal way of driving. The wind comes from the rear and pushes the ship forward. It’s just like people say “smooth sailing”. But for the entry-level sailors of small sailboats, downwind is quite difficult. The problem is that when downwind comes, the direction of wind is parallel to the ship, and there is no lateral pressure for balance. It’s easy to lose balance When a ship capsizes, it takes more than 16 hours to get used to it.

War is the highest form of struggle among political groups, nations (tribes) and countries (alliances). It is the most violent means to solve disputes. It is one of the ways to solve problems in nature. It is usually considered as a method only used in primitive society. As the war of aggression caused great harm to human beings, it is not recognized in modern human society.
