Week 4: Magnetism and Mind Mapping

Tuesday

On Tuesday, Dr. Walter Gekelman, an expert physicist, gave a lecture about magnetism and plasma. While explaining the definition and characteristics of magnetism to us, He brought instruments, such as magnetism and ferrofluid, to the classroom to let our hands-on and experience the magnetic fields. He had us try holding two magnets at different angles to attract or repel each other, giving us an idea of the north and south poles of the magnets. He showed us that under the action of a magnet, charcoal appears along the flow of the magnetic field. The direction of the magnet and the magnitude form many semicircular arcs. From south to north of the magnetic field, the farther the magnet is, the weaker it is. He also showed us ferrofluid, a nano-technology-grade liquid material that deforms under a magnetic field. The first half of the whole class is very interesting and hands-on so we can understand the concept of the magnetic field in an easy-to-understand way and immerse ourselves in it. This experience brought me back to my high school physics class, recalling those familiar and unfamiliar definitions such as vector, Maxwell's Equation, energy principles of electricity, and electromagnetism.

What impressed me the most is that the doctor said that when there are only two masses in an independent space, the two masses will attract each other, and the object of the small mass will fly to the object of the large group due to the magnetic field. From a microscopic point of view, each atom has a positive inner core and small electrons surrounding the spin. And when countless atoms add up, animals, plants, and countless other creatures on the earth will be formed. Therefore, I think that the mutual attraction and repulsion in electromagnetism can also be reflected in the mutual attraction between human beings and between human beings and animals on a macro level. Many social phenomena can be seen in these scientific events every time.

In addition, Dr. Gekelman also explained some ways of generating electricity in human society, such as steam thermal power generation, which can generate electricity through waterfalls, and electromagnetic power generation. When he explained the principle of electromagnetic power generation, he used **Faraday's Law of Induction to explain the principle that humans can generate electricity through electromagnetism. Then he highlighted the role of the minus sign in this equation: it is used to remind people that the power of nature is not inexhaustible, and human beings should remain in awe of the energy provided by nature and cannot completely rely on it. And unscrupulous is the use of energy. Dr. Gekelman's explanation combined seemingly rational scientific laws with empathetic humanities, which gave me a new perspective on science. Scientists also take humanity into account when defining these concepts. This inspires me a lot. 

Thursday

On Thursday, we recalled what we had learned in the past four weeks in class and connected the keywords on the whiteboard.

Next, we also talked about the subject of the final project that everyone is interested in. I want to study the connection between the brain, emotion, and visualization. Among them, I want to specifically study DINK(DOUBLE INCOME NO CHILD)

DINK's Dilemma

DINK's Refusal to Childbirth: DINK is currently widely spread among Generation Z. After encountering extensive one-right-way education and a severe introduction to the job, Generation Z members are frequently unwilling to have children and opt to join DINK. when they can earn money to enjoy the moment of life and their independence. Moreover, they do not wish to worry about their children's future anxiety and introversion.

Employment Market Saturation: The job market is nearly saturated with applicants with good academic credentials, and these talented and competent individuals are competing for additional hours and base compensation. Interested in starting a family

Schooling's Nightmare: Children of the Z Generation have felt the pressure of omnipresent education to some degree. They take exams for the sake of exams and study dull material to avoid being reprimanded. Efforts are fruitless. of their children after experiencing it themselves.

The physical and psychological torment of female reproduction: childbirth is unpleasant for women, and even while modern medicine offers pain relief, it cannot cure the problem entirely. However, in Asian societies, the weight of childbirth is often viewed as the responsibility of women, and women's behavior is frequently scrutinized while men's behavior is generally tolerated.

Interior emptiness: When they observed their colleagues' children and grandchildren in middle age, the DINK seniors around me felt lost, puzzled, and void. They have a good income and a busy and free life, yet they lack parental affection for their children. Some individuals opt to keep dogs as an emotional outlet. However, pets have a limited lifespan. The botanical garden I've presented can provide this type of DINK individual with an immersive environment in which to raise offspring in the virtual world using AI and can solicit their output and input. The need for love can also be used to avoid the actual pressures of parenting and social rivalry. DINKS may select their progeny from this garden as rapidly as they select fruit from an orchard, snatching their grown children as they fall to the earth in a utopian ideal and raise their offspring in a virtual environment. I found myself at a crossroads in my life at the age of 22. Using the augmented environment, I am attempting to identify alternative methods for addressing this social and moral challenge.

In the second half of the class, we invited Santiago Torres, an astrophysicist, to give us a lecture. Among them, I am most interested in his research on sound.he also speaks of a lot of interesting projects with sound. He worked on the sound of the atmosphere between the non-polluted ones and the polluted at once and he concluded that the polluted atmosphere usually has noises while the clean atmosphere is very calm by visualizing those sound, expanding the frequency and vibrations. Play with sound could be a very interesting expression for both scientists and artist to pursue in the future as all human behaviors are generated by vibrations and frequency and such vibration could be transported into data and finally in sound or visualization.
