Java Programming - Change Calculator High quality version at: http://www.stage6.com/user/MetalGearL... If you want to see the code more clearly, please click the above link! This is a short video of me in real time, programming a small application in Java, using JCreator. I did make some mistakes, I missed off 5 semi-colons. I fixed this when I ran the compiler, which isn't shown. Please comment and rate. I'm only currently learning Java. So this is a very simple program that runs using a basic output, such as JCreator's General Output window or a Command Prompt window. In this video, you see it running from JCreator's General Output window. I may do another video like this. Perhaps something more complicated when I have an idea. If anyone has a question about the code in this video, I'll try to answer it. Thank you. *This video is in the "Science & Technology" category because it's sort of "technology" related.

Charles Babbage and his Difference Engine #2 [Recorded: April 2008] Charles Babbage (1791-1871), computer pioneer, designed the first automatic computing engines. He invented computers but failed to build them. The first complete Babbage Engine was completed in London in 2002, 153 years after it was designed. Difference Engine No. 2, built faithfully to the original drawings, consists of 8,000 parts, weighs five tons, and measures 11 feet long. OVERVIEW - In London, during the summer of 1821, Charles Babbage, inventor and mathematician, is poring over a set of astronomical tables calculated by hand. Finding error after error he finally exclaims 'I wish to God these calculations had been executed by steam'. His appeal to machinery, in one of the most resonant utterances of the 19th century, was the start of a new era of automatic computation. It was not only the grindingly tedious labor of verifying a sea of figures that exasperated Babbage, but their daunting unreliability. Engineering, astronomy, construction, finance, banking and insurance depended on printed tables for calculation. Ships navigating by the stars relied on printed tables to find their position at sea. The stakes were high. Capital and life were thought to be at risk. Babbage embarked on an ambitious venture to design and build mechanical calculating engines to eliminate the risk of human error in the production of printed tables. The 'unerring certainty of machinery' would solve the problem of human fallibility. His work on the engines led him from mechanized arithmetic to the entirely new realm of automatic computation. Tabular errors provided a practical stimulus. But this was not his only motive. He also saw his engines as a new technology of mathematics. Babbage himself failed to build a complete calculating engine and his designs remained an historical curiosity for over 150 years. Finally, in 2002, the first full-size Babbage Engine (Difference Engine No. 2), built faithfully to the original designs, was completed at the Science Museum in London, the culmination of a seventeen year project. The Engine consists of 8,000 parts, weighs 5 tons and measures eleven feet long and seven feet high. It works as Babbage intended, and brings to a close an anguished chapter in the prehistory of computing. A MODERN SEQUEL - A duplicate engine is on display and demonstrated at the Computer History Museum in Mountain View, California till May 2009. It is a sumptuous piece of engineering sculpture and an arresting sight in operation. This video is from that exhibit.

Algebra: Solving Linear Equations -- Part 1: The Basics [NOTE: This video is only the first 18 minutes of the full lesson, please visit my website to purchase complete version] Lesson consists of providing you with a Self-Tutorial on how to solve linear equations. Tutor discusses what is an Equation, Solution, Solution Set, Equivalent Equations, Identity, Contradictions, Conditional Equations, Linear Equations, the Standard Form of a Linear Equation. I show you how to actually SOLVE linear equations going step-by-step. I don't skip steps. I review some of the properties of Equality here too. I remind you to check the work done and how to solve linear equations using a calculator. At the end, you will know how to easily solve equations that look like: 2[y - (4y - 1)] = 5 - 9y No word problems are done here. This is shown in DETAIL in Part 2 of the Lesson.
