What is a vector? Is it an arrow in space? A list of numbers?

In this video Paul Andersen explains how covalent network solids form elementally (like graphite) or by combining multiple nonmetals (like quartz). Covalent network solids contain elements from the carbon group because they have four...

A tesseract is a 4D cube, i.e. a cube that exists in 4 dimensions. Although fans of the Marvel universe and superheroes may associate tesseract with the glowing blue box that houses the Space stone, a tesseract is a real geometrical...

While a barcode only holds information in the horizontal direction, a QR code does hold information in both horizontal and vertical directions. Due to this, a QR code holds hundreds of times more information than a barcode.

Mr. Addit reviews two and three dimensional figures.

While a barcode only holds information in the horizontal direction, a QR code does hold information in both horizontal and vertical directions. Due to this, a QR code holds hundreds of times more information than a barcode.

What if the universe had a higher dimensional twist in it?

We argue van Gogh's Bedroom in Arles rescues individual perspective and reacts to the impact of culture on the individual.
