The reason smartphone batteries are getting bigger but lasting less time is due to damage to the electrodes and electrolyte that occurs during the repeated charging and discharging of lithium ions. This degrades battery performance and reduces its lifespan. To prevent this, it’s important to keep your battery at the right temperature and improve your charging habits.   If you look at...

While advances in science and technology have a positive impact on human life, they can also lead to negative impacts, such as military weapons and environmental degradation. To prevent this, engineers need to be ethically responsible, and universities should strengthen engineering ethics education so that engineers can make the right decisions.   Today is the age of science and technology...

Iceland is a volcanic island located on the boundary between the North American and Eurasian plates, an area of active tectonic movement. From a plate tectonics perspective, Iceland is important for geologic research and is considered a unique place to observe the expansion of the two plates and the formation of new crust.   Iceland is a volcanic island with very active tectonic movements...

E-paper is a technology that combines the best of both paper and display, and can improve the reading experience while compensating for the shortcomings of traditional paper media. Despite initial technical limitations, e-paper is rapidly spreading across a variety of sectors, including publishing, education, advertising, healthcare, and more, and has the potential to significantly change the way...

In the face of exponentially growing energy demand and the threat of fossil fuel depletion, humanity is preparing for a transition to renewable energy sources, including geothermal energy, to address climate change and environmental pollution.   The time is coming when humanity must prepare to say goodbye to the fossil fuels that have served us for more than a century. The global population...

Charles Darwin’s theory of evolution confuses the concepts of evolution and progress, but in reality, evolution is not a process of perfection, but rather the selection of variants that are adapted to the environment of their time.   It’s no exaggeration to say that Charles Darwin’s theory of evolution changed the way we look at living things. But unlike the way we think of...

This article explores the reasons and implications of why people choose altruistic behaviors in their daily lives. People often sacrifice personal gain for the sake of others’ happiness and social relationships, and this behavior can ultimately lead to individual and societal happiness.   We have all had the experience of acting altruistically for others (in this article, altruism is...

This article discusses why the progress of science will inevitably come to an end. It argues that the inherent limitations of science, the finiteness of discoverable natural phenomena, the limits of human intelligence, and economic difficulties may bring about an end to scientific progress.   The human species has gone through many stages of evolution, starting with our primitive ancestors...

This article explores personal perspectives on death and grief, questioning whether people are truly mourning the departed or crying out of their own feelings of loneliness and loss. It is about rethinking the nature of grief as we come to understand and accept the boundaries between life and death.   From a young age, I lived in the same house with my grandparents, but we were not close...
