Fun Math Games: How Can You Have Fun With a Math App?

Fun math games seems like like a contradiction in terms. If you are anything like me, then the thought of spending leisure time doing sums is not necessarily appealing. But that is where an iPhone or iPad math app can make the difference. A cool math game has the ability to help you forget that you are actually doing arithmetic, and instead keep you entertained and addictingly glued to the screen.

Aimed at both adults and children who have basic counting skills, fun math games are educational. However, the adults and kids alike will become engrossed in the competitive nature of these games, posting scores to Openfeint or Games Centre to see if they can beat their best score, and will quickly forget that they are using their brain in a way that their math teacher would happily approve of.

A math app can be cunningly disguised as a fun game for young children. Once they become engrossed with the characters or story, the addition, subtraction, spatial awareness or problem solving puzzles become entertaining and engaging and can keep a youngster amused for quite some time and on a recurring basis.

Fun math games aimed at adults include the old faithful games such as Sudoku, the new classic game Tetris, and even the immensely popular Angry Birds which uses a player’s knowledge of angles and velocity, although without you really thinking about it and dreading playing a math game! The addicting quality of any of these games takes over and the player is fully engaged and determined to win. That is the sign of a great game.

Why use an app instead of paper and pencil? Well, I would not argue that paper and pencil make a very entertaining option if that is all you have. But the options with apps are huge and becoming greater every day. Most game apps are free or very inexpensive. Graphics are entertaining and lively for children, and engaging for adults. Different play modes are available allowing you to choose the type of game you feel like playing today, and you have the option of scores being compared with others all over the world. Now why would you choose paper and pencil?

If, like me, you think math is not appealing, then I would suggest you try a math app for iPhone, iPod touch or iPad. It might just surprise you how much you enjoy it, and your brain might like the workout from fun math games!

MoS2 Low Friction Coatings – Not Just For The Aviation Industry Anymore

MoS2 low friction coatings (also known as molybdenum disulfide, also spelled, disulphide) are regarded the most widely used form of solid film lubrication today. What makes them unique (with the other dichalcogenides) is the weak atomic interaction (Van der Waals) of the sulfide anions, while covalent bonds within molybdenum are strong.Thus, lubrication relies on slippage along the sulfur atoms. All the properties of the lamella structure are intrinsic. No external form of moisture is required. In fact, best performance from MoS2 low friction coatings is attained in the absence of water vapor, which are prone to surface adsorption. This makes them ideal under vacuum.There are a number of methods to apply MoS2 low friction coatings, including a simple rubbing or burnishing, air-spraying resin-bonded or inorganically bonded coatings, and more recently by sputtering through physical vapor deposition (PVD).Thickness will vary, depending on form of MoS2 low friction coatings, but typically ranges between 5 to 15 micrometer. Sputtering techniques can produce thin films of 0.2 micrometer. While plasma sprays will result in higher builds, beginning at 0.003 inch or more.Friction coefficient less than 0.05 is attainable, but will also vary with humidity and sliding conditions. Tests show friction decreases with increasing vacuum strength. Friction also lowers with higher load, faster surface speed, or both. In fact, MoS2 low friction coatings are superior to both graphite and tungsten disulfide (WS2). Friction with MoS2 low friction coatings is independent of particle size, though the larger particles can carry more load.Dry lubrication for MoS2 low friction coatings remains superior at higher temperatures, with oxidation rates remaining relatively low at temperatures up to 600 degrees Fahrenheit. And in dry, oxygen-free atmospheres, lubricating performance, even with oxidation products, is stable to 1300 degrees Fahrenheit.Higher air flow can affect oxidation kinetic rates in atmosphere. Molybdenum oxide products (MoO3) and sulfur dioxide. Since MoO3 alone offers dry lubrication, based on its relative softness, molybdenum disulfide coating are ideal in higher temperature environments. At higher temperatures, though, they are better suited under vacuum. In atmosphere, they are prone to water adsorption from air based on their hygroscopic properties.As with the other dry film lubricants, while differences may prove negligible, you will have to determine which is better for you: longer wear life or better performance, using MoS2 low friction coatings. Generally, friction will be slightly higher by coating both surfaces, rather than coating one surface only. But wear life will increase coating both surfaces.Friction can be good in so many areas of life. Without it we could not easily stop and start our motion, or change direction. But in moving machinery, friction causes considerable loss of energy, poorer performance, not to mention limiting wear life.As with many non-lubricated systems, the static coefficient of friction is higher than the dynamic coefficient of friction. The resultant motion is often referred to as ‘stick-slip’. Basically, the two surfaces stick together until the elastic energy within the system has accumulated to some threshold, where a sudden, forward slip takes place. Under magnification, it’s apparent the union of two surfaces is often limited to intimate contact only at the tips of a few of the asperities (small scale, surface irregularities). At these point areas, pressures relating to contact may be near the hardness of the softer material. Thus, plastic deformation occurs on some localized scale. This is known as cold welding. Where bonded junctions are formed between two materials.For lubrication to occur, these bonds, this adhesive component of friction, must be broken. And this is where products like MoS2 low friction coatings serve well.So, where are these products used today? Consider aerospace, automotive, marine and electronic, for starters. There, you’ll find MoS2 low friction coatings, again and again.

Ontario’s Wine Industry – Harvesting the Benefits of SR&ED

How wonderful it is to proudly browse the wide selection of Ontario’s wines at your local LCBO. Knowing that your own winery is both a driving force in the Canadian economy and an innovator of the local wine industry can certainly be rewarding, both personally and professionally.From challenges to opportunitiesQuite often the goal of a grape grower to produce a consistent, high-quality brand of wine is met with many unexpected challenges. With the erratic situation of the Canadian economy following the recession, wine makers of Ontario struggle to produce at the risk of manufacturing downsizing. In addition to economic factors, the wine industry of Ontario is faced with a higher stringency under Vintners Quality Alliance (VQA) regulations, and the push from Wine Council of Ontario (WCO) to raise industry standards by participating in programs like Sustainable Winemaking Ontario.For the individual winery of Ontario, keeping up with competition means continuously utilizing new technologies and finding innovative ways to provide a premium product, despite such challenges. Simply put, this boils down to having the necessary financial opportunities become available to maintain a healthy competition. Are these opportunities available to the wine industry of Ontario? Yes – SR&ED is the answer!The SR&ED programThe SR&ED program (Scientific Research & Experimental Development) aims to reimburse companies for their experimental development expenses. For over 20 years and with about $4 billion a year in funding, it remains the largest single source of federal funding for R&D in Canada. The goal is to make creativity and innovation affordable in the Canadian business environment and foster future development.The program is highly relevant to businesses who are naturally involved in shop-floor
experimentation. R&D projects that qualify under the program include (1) work undertaken for the purpose of achieving technological advancement and/or (2) creating new, or improving existing materials, devices, products or processes. The actual refund amount depends on proper identification and qualification of eligible expenditures.Wineries in Ontario serve as ideal candidates for such funding.
