List of mathematical symbols When reading the list, it is important to recognize that a mathematical concept is independent of the symbol chosen to represent it. For many of the symbols below, the symbol is usually synonymous with the corresponding concept (ultimately an arbitrary choice made as a result of the cumulative history of mathematics), but in some situations a different convention may be used. For example, depending on context, the triple bar "≡" may represent congruence or a definition. Further, in mathematical logic, numerical equality is sometimes represented by "≡" instead of "=", with the latter representing equality of well-formed formulas. In short, convention dictates the meaning. Each symbol is shown both in HTML, whose display depends on the browser's access to an appropriate font installed on the particular device, and in TeX, as an image. Guide[edit] This list is organized by symbol type and is intended to facilitate finding an unfamiliar symbol by its visual appearance. Basic symbols[edit]

Remember, there are no right or wrong answers, only your answer. Click the game area, turn up your speakers, and relax. If you don't see the game, you may need to update your Flash player, or disable any flash blockers you may have enabled. If you enjoyed the demo, we highly recommend trying out the full version of the game which has 70+ levels spread across 15 Acts.
Game Development Math Recipes One of the most daunting aspects of game development for many people is the mathematics involved. The following are a collection of recipes that go into detail on how to perform a number of common math related tasks. Each example ships with at least one working demonstration application (written in JavaScript using EaselJS), with complete source code. Don’t worry if your language of choice is C++, C# or Java, the JavaScript code is easily ported to any C derived language. In every case the code is written to favour readability over performance.

Blog - 5 Steps to $5,000 in Monthly Recurring Revenue It's been 6 months since we launched the first version of StatusPage. Looking back on this early phase of our company, we thought it would be helpful to talk about how we got to our first $5,000 in monthly recurring revenue. As we continue to grow and hopefully reach $25,000, $50,000 and $100,000 in monthly recurring revenue, we'll follow up with new blog posts detailing how getting to each milestone is different than the one before. Let's get to it. Step 0: Find A Problem Worth Solving As web developers, we consistently rely on a multitude of web services to build our applications. Thinking through our problem a bit more, we had a hunch that all other developers feel the same way. The problem Companies don't want to spend the time and money to build and maintain status pages outside of their infrastructures, instead, preferring to work on their core products. The hypothesis Step 1: Get To Hacking What we did We're fortunate to be building a product that we wanted to exist in the world.
Bump Mapping Using CG - By Søren Dreijer Imagine an ordinary 2D texture. The surface of this texture is plain flat and therefore the normals of the texture surface go straight up, as shown in the picture below. That's why, when you step close to, say, a wooden box in a game, the box doesn't appear like it has any depth. That's the results we get when using boring 2D textures.. The solution to this problem, however, is to vary the light intensities across the texture as we render. Below is a screenshot of an actual normal map (which probably looks a bit weird at first): Notice the three axes I've drawn in the bottom left of the texture; the x-axis points to the right, the y-axis points upwards while the z-axis is pointing out of the screen. What we really want to do is to interpret the color at any given texel as the direction of the normal at that position. Now that we have a way to read and interpret the directions of the normals at each texel from the normal map, we're ready to continue. Ok, so far so good. , where
Vector Math Tutorial for 3D Computer Graphics Fourth Revision, July 2009 This is a tutorial on vector algebra and matrix algebra from the viewpoint of computer graphics. It covers most vector and matrix topics needed to read college-level computer graphics text books. Most graphics texts cover these subjects in an appendix, but it is often too short. A mirror site that contains this material is: Mirror Site Computer graphics requires more math than is covered here. Although primarily aimed at university computer science students, this tutorial is useful to any programmer interested in 3D computer graphics or 3D computer game programming. This tutorial is useful for more than computer graphics. These notes assume that you have studied plane geometry and trigonometry sometime in the past. These pages were designed at 800 by 600 resolution. Some sections are years old and have been used in class many times (and hence are "classroom tested" and likely to be technically correct and readable).
Former contractor breaks down communication barriers with ELSA, a device that speaks 180 languages | Equipment World | Construction Equipment, News and Information | Heavy Construction Equipment Charles Howerton on the jobsite wearing and using his ELSA device. Imagine yourself in the middle of an important project. You need to tell your workers about a crucial step in the building process. You attempt to speak with them, but all you get in return are several confused faces. You’re clearly not getting through. This was the place Charles Howerton found himself seven years ago. Born out of frustration With 17 years of construction industry experience under his belt, Howerton knew the ins and outs of the business. After a hailstone storm hit Minnesota in 2005, Howerton’s company faced a huge influx of work. To communicate with these new workers, he hired a bilingual interpreter. The issue came to a head when Howerton needed several Hispanic landscape workers to move out of the way at a multifamily housing project he needed to access. “It was like synchronized swimming,” says Howerton of how quickly the workers moved. Live interpretation on the go

MATH/PHYS 191 – Math & Physics for Games I - JCCC MATH/PHYS 191 Four reasons you may be missing deadlines and how to fix these problems When a deadline isn’t met, it is often because of a breakdown in one or more of these four areas: Time managementPrioritizingImpulse controlCommunication Time management Most people underestimate the amount of time it takes to complete a task. To get a more realistic idea of how long it takes you to do something, start timing your processes throughout the course of a day. In the meantime, I recommend doubling your time estimations for completing a task. Also, remember that your coworkers and clients are also underestimating the length of time it will take them to complete work. Prioritizing Whether it’s because you don’t want to do the work (the task you need to finish now is less desirable than another project further down on your to-do list) or you can’t do the work (such as the building is on fire and getting out of the building is in your best interest), incompatible priorities are often the cause of missing deadlines. Impulse control Communication
