On this day, 240 years ago, the French physicist and mathematician André-Marie Ampère was born in Lyon, France. Recognized as a founder of electrodynamics — or what is today known as electromagnetism — Ampère helped establish a theory defining the relationship between electricity and magnetism. We continue to celebrate the importance of his discovery in creating the groundwork for future developments in both of these fields.

The use of 3D structures in the design of pop-up books is a unique tool that fosters engagement in reading. Within the scientific community, researchers have found a use for these same fabrication techniques in the development of new technologies. We discuss these “pop-up” techniques and how they have shifted from libraries to research labs.

Could there be a substitute for indoor heating in the future? New research from Stanford University suggests that highly insulating clothing may provide enough heat that we can reduce or even eliminate the need for traditional heating systems. Today, we explore this research as well as other fabrics favorable for staying warm — and cool.

Depending on their magnitude and frequency, vibrations can be a source of discomfort and even pain for the human body. The impact of these vibrations is surely felt, but wouldn’t it be interesting to visualize how different parts of the human body respond when placed in such an environment? We introduce you to a multibody model that enables you to analyze the body’s dynamic response to vibrations.

Among its neighboring buildings on the Las Vegas strip, the Vdara® hotel can be identified by its unique crescent-shaped design. While visually appealing, this architectural element became an area of concern as it contributed to the development of a caustic surface on the hotel’s pool deck. As a result, guests at particular locations experienced severe sunburns at certain days and times of the year. Here, we model the generation of a caustic surface in the case of the Vdara® hotel.

When the Newtonian telescope was first developed in 1668, it was recognized as the earliest operating reflecting telescope. With its low cost and simplistic design, this optical system became a favorable alternative to refracting telescopes, and the technology continues to be widely used today. Using the Ray Optics Module, we can analyze ray propagation within this type of telescope system.
