It depends on your supply voltage. You have to be able to overcome the cumulative forward voltage of the series combination in order to get them lit. As an example, with a 12 VDC supply, you could drive up to five red LEDs (2.1V @ 20 mA) in series. The current isn’t used in the calculation: 5 * 2.1V = 10.5, which is less than 12, but 6 * 2.1V = 12.6 which is over 12, so five is the maximum series combination for that type of LED at that supply voltage.

Feature Column from the AMS The inflated tiling is itself a tiling by thick and thinrhombs and, as such, it has an inflated tiling as well. This creates,from a single tiling, an infinite hierarchy of tilings in which eachtiling is the inflated tiling of its predecessor. Introduction: Tilings Tilings, like the one below, show up in many places in the world around us, from the tiles on our kitchen floors to the bees' honeycombs. They generally have a pleasing, even fascinating, quality, their regularity often expressing some natural harmony. Feature Column from the AMS
Penrose Tilings Penrose Tilings Kyle Schultz This webpage provides an introduction to Penrose Tilings and their properties. Discovered by Roger Penrose (1931- ), a British physicist and cosmologist, these tilings are non-periodic and incorporate properties of the Golden Ratio. Tilings A tiling is created when a collection of plane figures (tiles) fills a plane such that no gaps occur between the tiles and no two tiles overlap each other. Penrose Tilings

my pentagonal coffee table my pentagonal coffee table The pentagonal coffee table that was mentioned in Dissections: Plane & Fancy, by Greg N. Frederickson: Dick Ruth (at Shippensburg University, Shippensburg, Pennsylvania) asked to see some pictures of the pentagonal coffee table that I had designed and which was mentioned in my biography. Here are two photos that I made before I installed the glass top.
Ancient Islamic Penrose Tiles When Peter J. Lu traveled to Uzbekistan, he had no idea of the mathematical journey that he was about to embark on as well. Archway from the Darb-i Imam shrine in Isfahan, Iran, which was built in 1453 C.E. The larger pentagons outlined in pale blue were constructed using a large-scale girih tile pattern, and the small white pentagons were constructed using a small-scale girih tile pattern.

Polygons, Tilings, & Sacred Geometry Slide 5-1: Pompeii pavement Calter photo In the last unit, Number Symbolism, we saw that in the ancient world certain numbers had symbolic meaning, aside from their ordinary use for counting or calculating. In this unit we'll show that the plane figures, the polygons, triangles, squares, hexagons, and so forth, were related to the numbers (three and the triangle, for example), were thought of in a similar way, and in fact, carried even more emotional baggage than the numbers themselves, because they were visual. This takes us into the realm of Sacred Geometry. For now we'll do the polygons directly related to the Pythagoreans; the equilateral triangle (Sacred tetractys), hexagon, triangular numbers, and pentagram.

Donald Miller I used to play golf but I wasn’t very good. I rented a DVD, though, that taught me a better way to swing, and after watching it a few times and spending an hour or so practicing, I knocked ten strokes off my game. I can’t believe how much time I wasted when a simple DVD saved me years of frustration.

Universal robotic gripper

Robert Barker/University Photography The human hand is an amazing machine that can pick up, move and place objects easily, but for a robot, this "gripping" mechanism is a vexing challenge. Opting for simple elegance, researchers from Cornell, the University of Chicago and iRobot Corp. have created a versatile gripper using everyday ground coffee and a latex party balloon, bypassing traditional designs based on the human hand and fingers. They call it a universal gripper, as it conforms to the object it's grabbing, rather than being designed for particular objects, said Hod Lipson, Cornell associate professor of mechanical engineering and computer science.

Geodes can be grown without using egg dye. The resulting crystals are clear to milky white, like quartz. While large chicken eggshells are suggested in this process, larger eggshells can be used.
