Determining the size of an Earth-size exoplanet by the amount of starlight it blocks hundreds of light-years away once was the realm of science fiction. Measuring the mass of such a small planet based ...

Working with a device that slightly resembles a microscopically tiny tuning fork, researchers at the University of Tsukuba in Japan have recently developed coupled microcantilevers that can make mass ...

Recently in my physics lab, students were having trouble with the difference between mass and weight. I had ready answers---it’s a topic I’ve gone over hundreds of times. But after I explained that ...

Astronomers report the exciting discovery of a new way to measure the mass of supermassive black holes in galaxies. By measuring the speed with which carbon monoxide molecules orbit around such black ...

How does one go about measuring the mass of an object? Mass is defined as the amount of matter an object contains. This is very different from weight, of course, as the mass of our object would remain ...

1. Arxiv – A LEGO Watt Balance: An apparatus to demonstrate the definition of mass based on the new SI National Institute of Standards and Technology (NIST) researchers have designed and built a watt ...

In science, there are thousands of ways to measure the world around us that the average person may never encounter. For example: Pascals to measure pressure, Candles to measure light intensity, and ...
