Two kinds of cognitive depth tourism

Deep tourism is divided into humanistic deep tourism and natural deep tourism. The depth I'm talking about here refers to the cognitive depth and humanistic aspect, which requires strategy beforehand and summary afterwards. After seeing several famous churches, you need to learn relevant religious knowledge. For example, what is the difference between Catholicism, Protestantism and Orthodox Church? Catholicism is often in Gothic architectural style, with gorgeous decoration and magnificent appearance. Is there a more essential difference than the exterior and interior of a building? If so, what is the underlying logic behind it?

Unlike Sophia Cathedral in Istanbul, the Orthodox Church has a huge dome. Just like St. Vasily's Cathedral in Moscow, there is a garlic head.

Protestant churches are quite simple, without stained glass windows and statues of the Virgin Mary. Yes, the external architectural style also has many cultural connotations. But the deeper difference comes from another source.

That is the mark left by the Reformation, because the Reformation was an important reason for the Renaissance in Europe. At that time, the Roman church was quite corrupt and sold a large number of atonement vouchers. Martin Luther's religious reform made ordinary people go beyond well-dressed faculty and face God. At this time, printing promoted the religious reform, and everyone could face God directly through the Bible.

The "flattening" of Protestantism has given more expression to the humanistic spirit. In Protestant churches, you will never see a confessional again. Remember, in "Red and Black", it was through repentance that Mrs. Reina sent Julien to the guillotine.

So, what about natural deep swimming? In nature, there are countless magical creations of God. Maybe you are used to it, but that may be the "scenery" you missed. You can take out your mobile phone and use Baidu camera or other more professional apps to help you identify the animals and plants in front of you. AI really adds a layer of understanding to the human eye, and the knowledge you don't understand will automatically come out to stand for you.

When plants just landed on the land from the ocean, they didn't have the leaves we see today, and even the developed roots were the structure that plants compensated for the drought on the land. Natural selection, survival of the fittest, AI can be your knowledge guide for future AR travel.

Why are the leaves green? What is it that autumn turns red and yellow? When the temperature drops and winter comes, why do big trees abandon their leaves coldly?

Coniferous plants belonging to gymnosperms, such as fir and cedar, all look like triangular structures from a distance. Why are coconut trees in Hainan so elegant? Broad leaves are concentrated at the top.

I don't fully understand it either, but the future AR tourism will be automatically annotated in detail.

I like painting myself, and I also like to observe the branches when I travel to see if there is any regularity. Our human looks are all locked by our own genes, and it seems that a tree can't find two identical leaves. How can branches be regular? But I still found that bifurcation can obviously reflect the fierce competition between the two forces. One is the gravity of the earth, which will pull the branches down, and the other is to resist its growth. The branching part is particularly obvious, and its life tension can be felt from the back of the arc. It gradually yields with the growth length. This is really helpful for me to draw trees.

Then I try to answer some questions raised before. The survival of species is conditional. Among them, the problem of energy conversion must be solved in the metabolic link. Mitochondria exist in animal cells. It is an ATP (basic substance of energy metabolism) machine, which is responsible for converting sugar into ATP, a universal energy currency. For the plants we are talking about here, it is chlorophyll, which can convert light energy. It only absorbs red light and blue light, so the color it emits looks green.

Then the leaves evolved into a "two-way foil" with a larger working area for photosynthesis, so it was also compensated. So why don't those coniferous forests in the north make progress?

You know, even by siphon force, it is impossible to send water to the crown of dozens of meters through the blood vessels in the trunk. Plants rely on leaves for transpiration, which is a double-edged sword and also volatilizes a lot of water.

In winter, this becomes a big problem. In order to survive the winter and protect cars, trees have designed a special detachment layer at the petiole root of deciduous plants. Once necessary, just like a gecko abandoning its tail, it will grind the hard-working leaves and kill the donkey.

As for discoloration, there are other reasons. Look at my popular science island and you should be able to find it. In short, seeing and understanding are different levels. What I'm talking about here is relatively simple, and it will eventually be implemented in the physical level of quantum mechanics, and each layer has its own wonderful place.

Reading is really an advanced tour. The process of dialogue with scientific and technological experts who write books and make statements is a "high-end metabolism" of your cultural life.

When traveling, what can you see from the seven-story bucket arch structure? China ancient buildings without nail wisdom? Or what kind of aesthetic tradition does cornices have? Maybe both. It varies from person to person.

Let's just say that everyone can see a different world, and everyone can understand a different world. If I ask, "Is the world in the book big? Or is the world outside the book big? " That's a matter of opinion.
