It’s weird to think Jim Nabors, The Snake Pit, and pounding a quart of milk have something in common, but these are just a few of the numerous official traditions that take place every Memorial Day weekend in Indianapolis, more specifically Speedway Indiana. But it’s not just the track that makes this place what it is. Upwards of 400,000 people attend, although no official attendance is reported, there is seating for 235,000 people. The track itself is a 2.5-mile oval and there is not a seat in the house that has a view of the whole track – that is how big it is. The Venue is what makes this race better than any other race on the planet. The chess match of when and how to pit, combined with the risk of human or mechanical error in the pit crew is true athletic theatre. A mistake in the pits can cost positions on the track and easily alter the outcome of the race. All these movements and actions are choreographed to take 6-10 seconds. At each pit stop, the cars get 2-4 new tires, each tire has five nuts that need to be unscrewed and re-screwed (tightly), and the car gets about 40 gallons of fuel – in 6-10 seconds. Over the course of the 500, the cars will make 5-6 pit stops. The nerves, the training, and the skill to process so many computations so quickly and precisely are nothing short of surgical.īehind every Driver, is the team. The athleticism and bravado it takes to drive a car as fast as it can possibly go straight at a 90-degree corner, only to lift your foot off the gas at the last milli-second, to beat the driver inches to your right or behind you or in front of you is something regular people cannot fathom. ![]() The tension and beauty in this danger is extreme and intoxicating.Įach race car has a team, the most notable member of that team is the Driver. Unlike NASCAR, where, “if you’re not rubbin’, you’re not racin’”, Indy cars are pretty precious and any contact will, best case scenario, mess up the aerodynamics, worst case and most likely, crash the car. The aerodynamics of an Indy are so good that if you were able to turn the track upside down, while traveling at these speeds, the cars would stick to the track and not fall off.Īnother important factor to these cars, is that the Indy car – like an F1 car – is considered ‘open-wheel’ racing. The average lap time for the polesitter in recent years has hovered around 228 mph. The top speed for a large oval, such as the 500, is about 235 miles per hour (down from a staggering 244). The car sitting in your garage is twice as heavy with 170 ponies under the hood. The typical Indy car weighs about 1600 lbs and the engine is approximately 650 horsepower. And yet, it has been said, what heaven is to Catholics, the Indianapolis Motor Speedway is to race fans – and everyone should experience that thrill at least once in their lifetime. ![]() ![]() Real loyalties to teams or drivers are only a fraction of the draw. It is an event in the first half of the race season, with very few of the cars or teams are based in Indianapolis. The Indianapolis 500 is different in every way. While to the uninformed viewer, a car race may simply appear to be a series of left-hand turns, a waste of gas, a redneck pastime, boring, dumb, stupid, or whatever dismissive term is most easily and readily applicable – indeed it is much more than that. Is the hyperbolic title of The Greatest Spectacle in Motorsports Racing truly apt? First, is it important to decide what a great sporting event is defined by the culmination of a season’s worth of wins/losses that pit the two best teams for a winner take all finale, fans of those teams packed into an arena or stadium (or bar, or home, or backyard) to cheer together for their respective team to win, a hail Mary pass, a walk-off home run, a last-minute goal to win? ![]() ![]() ![]() The game will not work with previous versions of the LOVE 2D game engine. ![]() Please note that Mari0 has been designed for the LOVE version 0.8.0 or higher.

Throughout the early 1990s, Apple had tried to create a "next-generation" OS to succeed its classic Mac OS through the Taligent, Copland and Gershwin projects, but all were eventually abandoned. Its graphical user interface was built on top of an object-oriented GUI toolkit using the Objective-C programming language. The kernel of NeXTSTEP is based upon the Mach kernel, which was originally developed at Carnegie Mellon University, with additional kernel layers and low-level user space code derived from parts of BSD. There, the Unix-like NeXTSTEP operating system was developed, before being launched in 1989. The heritage of what would become macOS had originated at NeXT, a company founded by Steve Jobs following his departure from Apple in 1985. In 2020, Apple began the Apple silicon transition, using self-designed, 64-bit ARM-based Apple M series processors on the latest Macintosh computers. In 2006, Apple transitioned to the Intel architecture with a line of Macs using Intel Core processors. MacOS has supported three major processor architectures, beginning with PowerPC-based Macs in 1999. ![]() After sixteen distinct versions of macOS 10, macOS Big Sur was presented as version 11 in 2020, macOS Monterey was presented as version 12 in 2021, and macOS Ventura was presented as version 13 in 2022. Apple shortened the name to "OS X" in 2011 and then changed it to "macOS" in 2016 to align with the branding of Apple's other operating systems, iOS, watchOS, and tvOS. Apple's other operating systems ( iOS, iPadOS, watchOS, tvOS, audioOS) are derivatives of macOS.Ī prominent part of macOS's original brand identity was the use of Roman numeral X, pronounced "ten" as in Mac OS X and also the iPhone X, as well as code naming each release after species of big cats, or places within California. All releases from Mac OS X 10.5 Leopard and after are UNIX 03 certified, with an exception for OS X 10.7 Lion. The first desktop version, Mac OS X 10.0, was released in March 2001, with its first update, 10.1, arriving later that year. During this time, Apple cofounder Steve Jobs had left Apple and started another company, NeXT, developing the NeXTSTEP platform that would later be acquired by Apple to form the basis of macOS. MacOS succeeded the classic Mac OS, a Mac operating system with nine releases from 1984 to 1999. Within the market of desktop and laptop computers, it is the second most widely used desktop OS, after Microsoft Windows and ahead of ChromeOS. It is the primary operating system for Apple's Mac computers. ![]() MacOS ( / ˌ m æ k oʊ ˈ ɛ s/ previously OS X and originally Mac OS X) is a Unix operating system developed and marketed by Apple Inc. ![]() ![]() In fact, in working with tessellating shapes and incorporating their patterns into his work, M.C. Escher have used the intriguing optical effect of tessellations to create a surreal mood. A branch of science known as x-ray crystallography studies the repeating arrangements of identical objects in nature, sort of a natural form of tessellation. Tessellating patterns cut across many different disciplines. He worked on the problem of creating a set of shapes that would tile a surface without a repeating pattern, called quasi-symmetry. In the present day, Oxford mathematician Sir Roger Penrose has devoted much time to the study of recreational mathematics and tessellations. In 1619, Johannes Kepler published the first formal study of tessellations. In fact, the nature of mosaic art naturally gives rise to some tessellating patterns. Sumerian wall decorations, an early form of mosaic dating from about 4000 B.C., contain examples of tessellations. Tessellation patterns are very old, and are found in many cultures around the world. For example, the "Fish n' Chicks" animation below shows how you can alter a square to create an irregular shape that tessellates a surface. Tessellations made from regular polygons (equilateral triangles, squares, and hexagons) are usually referred to as tilings however, tessellations can be made from many irregular shapes as well. Semi-regular tessellations, on the other hand, use a combination of different regular polygons, such as the pattern above, and you can typically see examples of these patterns in the tilework of bathroom and kitchen floors. You can find examples of these on chess- or checkerboards. Patterns using only one regular polygon to completely cover a surface are called regular tessellations. Circles, for instance, would not create a tessellation by themselves, because any arrangement of circles would leave gaps or overlaps.ĭespite the limitations on the types of shapes that can form this intriguing pattern, there are many varieties of tessellations. Not all shapes, however, can fit snugly together. There are usually no gaps or overlaps in patterns of octagons and squares they "fit" perfectly together, much like pieces of a jigsaw puzzle. Lizard tiles by Ben Lawson.Geometry formally defines a tessellation as an arrangement of repeating shapes which leaves no spaces or overlaps between its pieces. Hexagonal and rhombic tessellations from Wikimedia Commons. Triangular tessellation from pixababy.If you want to try a more complicated version, cut two different squiggles out of two different sides, and move them both.Color in your basic shape to look like something - an animal? a flower? a colorful blob? Add color and design throughout the tessellation to transform it into your own Escher-like drawing. The shape will still tessellate, so go ahead and fill up your paper.Then move it the same way you moved the squiggle (translate or rotate) so that the squiggle fits in exactly where you cut it out. On a large piece of paper, trace around your tile. Tape the squiggle into its new location.It’s important that the cut-out lines up along the new edge in the same place that it appeared on its original edge.You can either translate it straight across or rotate it. Cut out the squiggle, and move it to another side of your shape.Draw a “squiggle” on one side of your basic tile.The first time you do this, it’s easiest to start with a simple shape that you know will tessellate, like an equilateral triangle, a square, or a regular hexagon. Here’s how you can create your own Escher-like drawings. Tessellations are often called tilings, and that’s what you should think about: If I had tiles made in this shape, could I use them to tile my kitchen floor? Or would it be impossible? The first two tessellations above were made with a single geometric shape (called a tile) designed so that they can fit together without gaps or overlaps. So we’ll focus on how to make symmetric tessellations. ![]() ![]() It’s actually much harder to come up with these “aperiodic” tessellations than to come up with ones that have translational symmetry. The Penrose tiling shown below does not have any translational symmetry. Many tessellations have translational symmetry, but it’s not strictly necessary. ![]() The idea is that the design could be continued infinitely far to cover the whole plane (though of course we can only draw a small portion of it). \)Ī tessellation is a design using one ore more geometric shapes with no overlaps and no gaps. ![]() |
