For anyone interested in mathematics, Phetamines is the solution. For students who love to play math games with friends and/or family, Phet is the choice to make. It's a brand of educational games for children that is designed to teach them through various mediums. For example, it has been known that Phet can be used to teach the fundamentals of physics using the Penry-Porter Method as a reference guide. This particular method was first introduced in 1970 by James R. Phet, who taught at University of Colorado.
In order to get the most out of Phet, it's recommended that you run online simulations. This can be done by visiting the official website, where you will find several types of Phet games (think Tetris), which are extremely fun to play and also help develop critical thinking skills. If you want to play Phet with other people online, simply search for your favorite game on Google, type it in and click search, and you can then view the players around you and play with them via messenger or instant message. There are a number of different websites that have taken this initiative to allow you to play Phet with your friends; however, one of the most popular is University-of-Colorado's Phet Academy.
To get the full benefit of Phet, you can either download the phet game onto your computer or install Phet app on your iPhone or iPad. The former is obviously the fastest way to experience the game, but if you don't have a computer or device that's capable of running emulators, the latter is the only way to enjoy it on a daily basis. Install Phet app on your device - simply open the app and follow the onscreen instructions. You will be prompted to install the Phet simulator, which will enable you to play Phet simulations on your device (through the use of an internet connection, of course). This means that you can play Phet whenever you'd like - as long as there is a suitable network available to you.
