Nature project 2 Since I was young, I have been fascinated by the beauty and mystery of nature. The scientific explanation of nature could be defined as the forces controlling the events of the physical world. Since the dawn of civilization, men had done many experiments to refine our understanding of Nature. Although after many centuries, men still had not completely understand what was the law of nature, or maybe a broader approach, the law of Universe, and many regions were still waiting for us to explore. Scientists had simply divided the knowledge of sciences into three categories, which were biology and physics. I would like to talk about my experience with these two sciences and how they were related with nature. First, biology could be defined as the scientific study of the life and structure of plants and animals. To understand biology, we needed to know that cells were an organism's, such as plant's and human being's, basic structural and functional units. Many machineries, which were called organelles, were located in each cell and they had to do different kinds of job. Two most important cellular organelles were the mitochondria and the nucleus. Mitochondria was an organelle, which served as the site of cellular respiration. In other words, it meant mitochronia's main function was to produce energy and feed the cell. The ATP (Adenosine triphosphate) was the most common energy unit in every cell. No matter what kind of organisms they were, without ATP, they would not survive. The second most important organelle was the nucleus. Nucleus was an organelle that contained the chromosomes, which were association of genes that tied together in a DNA. In order to reproduce itself, the cells had to pass it genes to the newly created cell, and the next generation would have a copy of the original DNA. Thus, passing DNA was the method that how cells propagated themselves. One of the examples was the Littlefield tree. If we dissect the tree, we could see how intricate that living organism was. The Littlefield tree was made from many tiny plant cells and each group of cells had different functions, like doing photosynthesis or transporting water from the ground, as a way to produce energy or ATP. At the same time, the tree used its seed, which enclosed enough genes, to scattered to other areas, so that it could procreate new generations. I thought the cells efficient self-management is amazing. The cells seemed like tiny robots, and they rarely make any mistakes. They were very smart because they knew how to use their energy effectively and when was the right time to reproduce themselves. They were always discipline and self-conscious about their actions. When we looked at the Littlefield tree, we should not think of it as just a simple organism. We should perceive it as many cell group together and cooperate productively to survive in the environment. I think trees were epitomes of how all the living organism worked in the earth. Moreover, I felt that the Littlefield tree was very beautiful. With all these beautiful green leaves budding out of the branches, it truly showed that spring had finally arrived. The branches was coming out to all directions from the trunk, which seemed like the tree was trying to reach his numerous hands to help us. Although the branches and the leaves were swinging back and forth by the wind, the truck remained very stationary. The truck just stood still confidently without any sign of fidgeting. I guessed that the tree might wonder how come we were always in a hurry, and the pine tree seemed to tell us that we needed to slow down, and relax. Instead of rushing through everything, we should become part of the nature. Secondly, the another important subject was physics. Physics could be defined as the science dealing with the properties, changes, interaction, etc. of matter and energy. The basic unit was an atom, which contained a nucleus and one or more electrons. The nucleus was composed of protons and neutrons. In addition, the electrons orbited the orbitals in different energy levels. To see a bigger picture, we needed to understand that electrons and protons are the ones that attract other atoms, thus Ionic or Covalent bond would form. Due to bonding between each atom, matter was created. Physics was the law of nature and it governed the motions of all matters. Therefore, I believed that physics was the fundamental of all sciences. One of the most important laws in physics was energy conservation theory, which meant energy was neither created nor destroyed. For example, the plants received sunlight and the photosynthesis process helps convert the light energy to sugar as their primary source, which assisted the plants to grow. Then the animals such as human beings could eat the plants and took its nutrients. After that, we excreted the waste products from the plants, it would landed on the ground and decomposed and became fertilizer. At last, plants or seeds would use the fertilizer to sustain their growth. From this example, we could see energy transform into different forms in a cycle. No matter how energy transformed itself, energy remained constant and it would not be destroyed or created. Physics was an interesting and a very important subject in nature. I encouraged everybody should take some science class because it would definitely be beneficial to them in nature. With a scientific mind, people could have a broader approach to speculate everything differently in the world. For example, science could help us to understand the relationship within the cycle of plants and animals. Thus we would appreciate how intricate the process it was. Without science, I believed that human beings would never able to understand different interactions in the environment. We would become ignorant and incapable to grasp a bigger picture of what was happening in the nature. To become a better observant in the nature, I believed we did not need to observe different things that was just limited in earth. We should not restrict our imagination and speculate only objects that were closer to our environment. We should go a step beyond to observe things that we do not really familiarize with. One of my beloved interests was looking at the star. Since I was a little child, I often like to look at the stars especially during my free time. I always dreamed of sitting on a star so that I could have a panoramic view of the universe. Since I took an astronomy class in UT, my knowledge of stars had deepened. Also, I always wanted to share my interest about stars to everyone. Stars were very interesting. The scientists characterized the stars by their luminosities, diameter, and the masses. Usually the more massive the star, the hotter, larger and more luminous it was. Also, gases were everywhere in the universe. Thus, scientists believed the thick clouds or gases and dusts were the ones that created the stars. Moreover, they thought that some waves are also responsible for the formation of the stars. Stars were fun to watch because they were little diamonds that hung on the sky and sparkled beautifully. Historically, the stars had been a tremendous value for human beings. They were beacons that helped those of them who were lost. They were the ones that guided the sailors to travel across the ocean. Even if they were used not for guiding purpose, the stars helped decorate the sky and make the night more beautiful. The sky would become lackluster if the stars did not existed. The knowledge of science had helped human beings to come closer to nature since the dawn of civilization. Without science, we would lose our ability to observe nature or the universe completely. Although science gave us benefits such as having a better living standard, and more opportunities to approach nature, people did not use it properly. They used science as a tool to gain benefits or harm people. For example, the innovation of more powerful and destructible weapons or the negligence of chemical plant's waste products. If people kept using science unwisely, no sooner or later our ecosystem would be destroyed and we would loss part of our heritage that we were taken for granted from nature. Also, learning science was not enough to understand the interaction within nature. I believed that the best way was to use our knowledge and apply it whenever we explored nature. Moreover, we should be adventurous and explore places that no men have traveled before. Thus, we could gain a new and different type of experience, and left these wonderful memories in our heart for the rest of our lives.
