The Evolution of Night Vision Technology
From the addition of components to the use of new materials, night vision technology has grown tremendously since its initial debut in the 1930s. While the longevity and reliability of night vision devices have steadily improved, new research on graphene-based sensors for infrared detection may provide one of the most profound developments to date.
Video Tutorial: Introduction to Modeling Structural Mechanics
I have great news for anyone who is eager to learn the fundamentals of simulating structural mechanics in COMSOL Multiphysics. We have just published a completely revamped version of our video tutorial on the static bracket model. COMSOL Multiphysics version 4.4 and the Structural Mechanics Module are used to analyze the resultant forces, stresses, and deformations that occur on solid structures that are subjected to external loads.
Physics Make or Break the Comic Book Movie Illusion
The main feat for any filmmaker is to captivate the audience into accepting a new reality, to entrance us in an illusion. This is particularly difficult for comic book movie producers, as breaking laws of physics risks also breaking the illusion. Animators of The Amazing Spider-Man 2 tried hard to comply with physics — and they succeeded.
Why Room Acoustics Matters
Picture yourself on a deserted beach, eyes closed and just listening. It’s a windy day in September. Seagulls circle around a rock formation, the waves break up into foam. It starts to rain, so you record a sound snippet on your cell phone for later. You consider playing the clip on your car stereo, but you don’t, because you know it just isn’t the same thing. Besides the breeze and the ocean smell, what’s the difference? Let’s talk room acoustics.
Shaping the Future with Holography
When you hear the term hologram, what is your initial thought? Many people may associate the word with the rising use of human digital projections within the entertainment industry. Holography as a whole, however, has practical applications in various areas. Let’s take a closer look at how this technology works and how researchers are utilizing it today.
Hygroscopy of Brown vs. White Sugar, the Banana Bread Test
Baking is just like chemistry class, except you get to eat the results. Today, we narrow in on one ingredient in particular: sugar. More than just a sweetener, sugar serves several other purposes in baking. For one, it keeps our baked goods moist thanks to its hygroscopic properties.
Sometimes a Cigar Is More Than Just a Cigar
As a chemical engineer, I can’t just smoke a cigar and leave it at that. Here, I investigate the anatomy, structure, and chemical process zones of a cigar and show you a simple model of the temperature distribution of the smoke in a cigar as well as the concentration of oxygen.
Infrared Pothole Repair: A More Permanent Solution
Due to their hazardous nature, potholes are often addressed quickly using temporary repair methods. These short-term fixes tend to be inefficient, however, requiring additional future repairs. Infrared pothole repair is one method that could offer a more durable solution.
