Piezoelectricity is the conversion of pressure applied to an object into electrical energy, and it’s used in a variety of everyday technologies, including piano steps, airbags, and pacemakers. Piezoelectric devices are used to generate power from pressure changes or to transmit signals by detecting vibrations, and while they are less efficient, they are ideal for harvesting small amounts of...

  Concerns about radiation have increased since the 2011 Fukushima nuclear disaster, but it’s important to understand the concept and the principles of protection rather than just being fearful. Radiation is a high-energy electromagnetic wave that causes ionization of living organisms and structures, which can cause damage such as genetic deformities and infertility. The basic...

The birth of Dolly the cloned sheep in 1997 sparked a global debate about the possibility of human cloning. Human cloning, which uses nuclear gene replacement technology to create individuals with identical genes, has medical applications but can also raise issues of human rights violations and disregard for life. Ethical opponents argue that human cloning undermines genetic independence and...

  Science and technology have enriched human life, but this progress has come at the expense of nature and animals. In particular, animal testing has been considered a necessary step, but it is controversial due to biological differences and unethical issues. Nowadays, robots, AI simulations, and other technologies that replace animals are emerging, calling for a new research paradigm...

This article discusses semiconductors, the most commonly encountered of the many disciplines in electrical engineering. It covers why semiconductors are important devices because they are materials with properties that are intermediate between conductors and non-conductors, allowing them to control electrical conductivity. Through the addition of impurities, devices such as transistors can be...

This article argues that paternalism is not a natural selection or genetic instinct, but a cultural phenomenon that has been acquired in human society through memes. Unlike the paternalism of sea dragons and emperor penguins, human paternalism stems from social values and moral obligations rather than biological necessity. It is an acquired love, shaped by the influence of culture and values, and...

  As countries introduce systems to control and monitor individuals for crime prevention purposes, there are growing concerns about privacy and human rights issues. Biometric data collection and electronic ankle bracelet systems in the United States and Europe contribute to crime prevention, but they also pose the risk of abuse of power and human rights violations. While they may be...

  Romanticism is a literary movement that reacted against classicism and emphasized emotion and individuality, focusing on the free expression of feelings to move readers. Both Lamartine of France and Mahá of the Czech Republic depict life, death, and the relationship between nature and humans in their works. Lamartine’s Lake Fianna sings of love and sorrow in nature, while...

We will examine the humanization journey of a robot in the film Bicentennial Man and discuss the potential for robots to express emotions and perform social roles like humans, and the ethical and social acceptability of such a development. It explores the boundary issues that arise as robots become more human-like in appearance and capabilities, and the ways in which they will coexist with...

Advanced robotics technology is revolutionizing the medical field beyond its efficiency in the industrial workplace. Robotic arms with high degrees of freedom are enabling more precise and safer surgeries that go beyond human limitations. These technological advances are expanding the possibilities for medical robots and providing a safer surgical environment.   The development of advanced...
