In this blog post, we’ll take a look at the science behind how thermoses block conduction, convection, and radiation. They keep cold beverages cold and warm beverages warm. The ubiquitous thermos was invented over a hundred years ago in 1881, first by Weinhold, then by James Dewar in 1892, and is still in use today. It was originally called the Dewar bottle after its inventor, James...
In this blog post, we explore the implications of genetic design for a child’s autonomy and agency. The race of life begins with the sound of a child’s powerful cry. From the moment they take their first steps into the world until the day they turn their backs on it, they are constantly running. Parents stand by their children’s side, hoping to keep them one step ahead of...
In this blog post, we look at the dangers of hydrofluoric acid, a key ingredient in industrial development, and the technological alternatives to replace it. Many years ago, a hydrofluoric acid spill claimed the lives of five workers and caused the evacuation of nearby residents for over a month. The incident sent shockwaves throughout society and served as a wake-up call to the dangers of...
In this blog post, we’ll explore how the food and nutrition we consume every day affects our quality of life. Eating food is one of the most basic things we do to sustain our lives. More than just satisfying hunger, food is an important element of culture, tradition, and social interaction. People bond with family and friends over meals, share food at important events, and build...
In this blog post, we’ll explore how Biomedical Engineering, the convergence of bio and electrical engineering, can revolutionize the future of healthcare through a variety of examples. Today, we live in a time of rapid technological change. While there are many areas of technology, especially in electronics, communications, and computers, the rate of change is rapid and far-reaching...
In this blog post, we’ll explain how the uncertainty principle of electrons makes the laws of physics in the microscopic world different from our everyday life. In our daily lives, when we read a book or work on a document on a laptop, we take it for granted that the book or laptop stays in the same position, without questioning it. This sense of stability is partly due to the...
In this blog post, we’ll use a variety of examples and theories to explore why altruistic behavior can lead to greater long-term benefits, even if it seems like a short-term loss. A high school class has been assigned one of the school’s printers to print on, so the class decides to share the cost of A4 printing paper for the class to use. But at the beginning of the class...
In this blog post, we’ll explore the historical and structural background of why flutes are still classified as woodwind instruments, even though they are made of metal. Today, flutes are made of metal with a shiny sheen. This characteristic may lead many people to believe that flutes are classified as brass instruments. Flutes are typically made from a variety of metals, including...
In this blog post, we’ll take a look at the science behind the things we take for granted about our refrigerators. It may seem like a simple matter of moving the food to another location with a lower enough temperature to solve the problem. However, in the average home, it’s nearly impossible to find a place that can maintain the same temperature as a refrigerator, unless...
In this blog post, we’ll explore how the importance of electricity and the future of laser technology are connected in the modern world. Electricity has become indispensable in the modern world. Not only do we use it for physiological needs such as darkness, cold, and heat, but we also rely on it for transportation, communication, and recording. Electricity doesn’t just fulfill...
