A prism is a transparent object with three edges, which can be glass, optical material, etc. The function of a prism is to scatter light. For example, a beam of white light (composed of mixed light and multiple beams of light with different frequencies) irradiates one side of the prism. The light with different frequencies has different refraction angles in the prism. When it comes out on the other side, it will be separated into light with different frequencies (colors).

The meaning of prism tattoo is to tell us that thinking is to learn to have divergent thinking. We can’t stick to one grid. If we think from different angles, we will get different results. If we are more bold, we should concentrate our thinking and often use it in our daily life, work and study.

Wish you were here is the seventh studio album released by Pink Floyd. The album was recorded in Abby Road studio from January to July 1975 and released in September. Wish you were here, this song comes from the sincerity of a brother. There are several memory traces left in the brain of dead people. There is no praise or sorrow, but there is a real human nature in it, which is so real that your eyes are wet.

Wish you were here is the first album of Pink Floyd released by Columbia record company. The band members temporarily changed the distribution company because they had a conflict with the original EMI company.

Through the above experience, Roger Waters wrote the criticism of the record company’s pursuit of fame and wealth and lack of understanding of music into the lyrics of the album. At the same time, the memory of my best friend Syd has become another theme of this album.

Iguana is not only one of the largest lizards in America, but also a highly adaptable animal. It lives in various environments, including tropical forests, arid deserts and even water. If you want to approach the wonderful world of iguana, come with me!

Like all reptiles, iguanas are variable temperature animals and can survive freely even in hot climate, which is why you often see them basking in the wild. Whenever the temperature drops below 4 degrees Celsius, the iguana’s muscles basically lose vitality, and the iguana immediately enters hibernation.

In addition to maintaining balance when climbing and moving, the tail of an iguana can also be used for self-defense. When faced with predators or other threats, iguanas confuse their enemies by swinging their tails. Sometimes they break their tails and escape, but don’t worry, their tails will grow back. If a predator tries to eat an iguana, the sharp spines on the iguana’s tail will make it difficult for the predator to swallow.

There are thousands of fish species in the sea. After hundreds of millions of years of evolution, they have become diverse and fantastic. Up to now, human beings are still unable to explore deeper marine organisms. However, what we are talking about today is a kind of colorful fish species living in the vast ocean, which is a kind of fish that makes experienced sea fishermen fear, It’s a Moray eel.

Moray eel is a fierce carnivorous marine fish. It does not take any fish species in mind. It is one of the few fish species that can defeat natural enemies. Moreover, it will take the initiative to attack humans when disturbed by humans.

Moray eels are colorful and diverse. Their teeth are sharp and numerous. Their mouths are full of sharp tusks. After closing their mouths, the sharp teeth of large Moray eels are still exposed. They can generally grow 1 to 2 meters long. Of course, it does not rule out that some magical sea eels can exceed 3 meters.

As we all know, tattoos will be very painful. After all, it is a micro operation to pierce the skin. It is not painful or realistic at all. If you want to find the most painful part of the tattoo in your whole body, which do you think is it? I think it’s an armpit.

Why is tattooing in the armpit more painful? Because there are many sweat glands in the axillary cortex, and a large number of nerves and blood vessels are distributed at the same time. It is also a dense gathering of lymph glands. Therefore, axillary skin is one of the most sensitive and weak parts. In such a soft and weak place, it takes a few hours of needle pricking. It’s really difficult for ordinary people to survive.
