A tesseract (a four-dimensional cube) and the "shadow" it casts on a plane - the quasi-crystal discovered by Shechtman. According to Prof. Bartel, "The fact that a quasi-crystal is a "shadow" of a high-dimensional periodic crystal is not new in itself. We discovered that the casting is not only of but also of topological properties such as holes, distortions or vortices." Illustration: Florian Sterl, Sterltech Optics

Man vs. Machine: Who is better at identifying birds?

The "Merlin" bird identification app is being tested by expert birders and amateurs. What were the results, and why is it still less accurate in Israel?
