Out Of Hand

When it comes to smartphones, I'm happy to see that the standards are rising. They're getting easier to use, more functional, faster and with the exception of battery life, more usable. There is one problem though: screen sizes have really went out of hand. Literally. My first two touch screen phones, the HTC P3600 and the HTC Touch Cruise both had a 2.8 inch screens, which were too small. Then I bought the HTC Diamond 2 and received the HTC Magic, both with 3.2 inch screens, and things got better.

In computer science the term infinity is both a blessing and a curse, but it's certainly in use, both in theory and in practice. The question is, does infinity exist in real life? It does exist in math, but math is not "real"; It exists in statistics, but you cannot find a group or a population the size of infinity to test on; You can program an infinite recursive functions or loops, but you will eventually stop the recursion when you run out of resources, and stop the loop when you get bored. The physical world is not infinite. There is a limited amount of energy and matter, which is always kept. Yes, matter can be converted to energy and vice versa, but the sum of them won't change. The universe did not always
