Khan’s theory, an attempt to reconcile this mismatch, posits that we should instead mathematically treat outer space as a ...

Our best models of the cosmos don't add up — but that could change if the universe is actually made of a viscous 'fluid,' a ...

Conventional wisdom holds that an electric current never returns to its source nor follows a circular path. Instead, it flows from one electrode to another following a local electric field, obeying ...

Cosmologists are facing an unexpected puzzle. The latest observations do not perfectly match the mathematical model used for decades to describe the evolution of the Universe. This model, ...

Modeling the behavior of liquids is important for a wide range of applications, from industrial processes and medical devices to computer graphics and visual simulations. However, despite many years ...

From cars on a highway to a viscous fluid like oil, our understanding of electron behaviour is being changed by new research. In high school science class, we learned that plugging a cable into an ...

Advanced approaches, such as droplet-based microfluidic approaches with microchannels, suspended microchannel resonators, vibrating cantilevers, and piezoelectric resonators, have been proposed to ...

Traditional viscometers rely on capillary flow, and falling balls are simple and effective means for measuring fluid viscosity over a large range. However, their low measurement throughput and lack of ...

When two fluids don't mix well, they sometimes form strange patterns called "viscous fingering," or Saffman-Taylor instability. Studying these patterns can help scientists understand how to design ...
