Why Do Tennis Rackets Tumble? The Dzhanibekov Effect Explained…
If you toss a cellphone, tennis racket, wingnut, cereal box, or any object with 3 axes of rotation in the air, it will demonstrate this interesting and unusual effect…
How Do Bicycle Pedals Stay On?
Ever wonder why the left pedal of a bike has left-handed threads and the right pedal has right-handed threads, yet the pedals stay on when riding?
Modeling a Scatterer Near an Optical Waveguide
In the real world, most structures are more complex than a 2D dielectric slab. However, if you’re designing photonic structures, you can learn a lot about wave optics modeling from this example.
A Simulation App for Helical Spring Design and Analysis
Helical springs are found everywhere from medical devices to consumer and industrial products. Despite being commonplace for centuries, the design of a helical spring can be complex.
Teaching Transport Phenomena to Engineering Students with Apps
Dr. Amol Deshpande from BITS Pilani, Goa Campus is moving beyond traditional classroom lectures by building simulation apps that students use to visualize heat transfer and fluid flow concepts.
Optimizing an NIV Mask Design with Multiphysics Simulation
NIV masks offer a form of noninvasive monitoring and ventilation for COVID-19 patients, which lessens the need for ventilators and other mechanical respirators.
Modeling Waveguides that Support Multiple Modes
2 ways you can model a waveguide that supports multiple modes: add a PML that can be used to absorb any modes, or explicitly add ports for each possible mode.
Happy Birthday, Arne Tiselius
The “Tiselius Apparatus” could help determine the isoelectric point, molecular weight, and physical properties of proteins. Learn about the “Father of Electrophoresis” and his accomplishments.
