Here’s what you’ll learn when you read this story: A team of German physicists has built a fully working version of quantum mechanics that uses only real numbers. Complex numbers, built from a ...

In 1914 Erich Moritz von Hornbostel and Curt Sachs published a taxonomy of musical instruments based on how an instrument’s sound is produced. Those that make a sound when a stretched membrane is ...

Physicists from Heinrich Heine University Düsseldorf (HHU) have examined a fundamental property of quantum mechanics in collaboration with the German Aerospace Center (DLR). In the scientific ...

In this video series, I show you how to simplify rational complex numbers. We do this by eliminating dividing by an imaginary number. We can either do this by multiplying by i which produces -1 or ...

Many young children invent imaginary companions (IC) in the early years, also known as imaginary friends. An IC may be entirely invisible, or embodied in a toy or other object. As many as two-thirds ...

You may want to think that form numbers mean something, but most don't—they're just administratively next in line. The launch of Form 4547—the tax form you’ll use to make a Trump account ...

Imaginary numbers can seem confusing at first, but they play a powerful role in mathematics and real-world applications. This guide explains what imaginary numbers are, why they exist, and how they ...

A Pulitzer Prize finalist in the cartoonist category, Pat Bagley has worked for The Salt Lake Tribune for more than 45 years. He is one of roughly a dozen cartoonists still working at a major ...

In the 1960’s, a developmental psychologist named David Elkind coined the term imaginary audience to describe how young adults often assume that they are constantly being watched and judged by others.
