Shape memory materials, like the T-1000 in the movie TERMINATOR 2, are replacing conventional materials in aerospace, medicine, and everyday life, showing the promise of future technologies.   In the movie “TERMINATOR 2,” the Terminator “T-1000” tries to kill the protagonist “John Connor” by freely changing its body shape. The T-1000 is a threat to the protagonist because it can change its...

Humans have sought out objects of worship out of fear of nature and the supernatural, but data and its processing systems are merely tools and cannot be worshipped. Data will be subject to human control and will exist only as a means to an end.   The time has come when purely human abilities are no longer sufficient to process a large amount of data. Human weaknesses that have been well...

It highlights the impact that X-ray diffraction has had on scientific advances and its practical applications, and why it remains so important.  ...

Smartworking has been touted as an efficient management innovation that transcends the constraints of time and space and promotes a creative work culture, but it can also lead to problems such as increased workloads and stress due to over-connectedness.   In the business world, smartworking has become an efficient management innovation. Employees use smart devices and are no longer bound by...

Fossil energy has been the main source of energy for mankind since the Industrial Revolution, but due to environmental pollution, supply instability, and resource depletion, there are growing calls for alternative energy development. Alternative energies such as nuclear, solar, and wind power are environmentally friendly, but they have technical limitations and require continuous research.  ...

Perfume is a cosmetic product that has evolved from ancient times to the present day, and it has become an important tool for expressing personal identity beyond simply eliminating odors. Perfumes are divided into different types based on the amount of fragrances they contain, with three main scents: top, middle, and base notes, which change over time and give off their own charm.   How much...

This article explains how the four branches of aerospace engineering – structural mechanics, aerodynamics, propulsion, and controls – are applied to the design of airplanes and rockets. It covers the role and importance of each branch, and highlights the elements that are essential to the design and operation of airplanes and rockets.   Before we get into what aerospace...

This article explains the similarities between the process of making pancakes and the principles of foam glass, and explores how foam glass has a number of advantages as a building material, including thermal conductivity, water resistance, and durability. The pore structure of foam glass and the practical and environmental benefits of using recycled glass are also emphasized.   Sweet and...

Curtain walling is an innovative way of covering the exterior of a building with glass, which has given skyscrapers greater design freedom, enhanced functionality, and become an integral part of the urban landscape. It combines the aesthetic value of architecture with energy efficiency, and has the potential to continue to evolve in the future of architecture.   Recent advances in building...

The development of the theory of evolution from early speculation to Darwin’s theory of natural selection, modern biology seeks to redefine the direction and superiority of evolution through the diversity of genes and gene combinations. Evolution is an inherently irregular process, and understanding how adaptation and change occur in living things is deeply connected to our philosophical...
