robots that walk‚ talk‚ appear human‚ and also make friends with people such as a human would do. We need to examine the meaning of the word artificial intelligence. All textbooks define the field as "the study and design of intelligent agents" where an intelligent agent is a system that perceives its environment and takes actions that maximize its chances of success. John McCarthy‚ who coined the term in 1956‚ defines it as "the science and engineering of making intelligent machines.” Reading these

designed this complex chemical in hopes that they could make a substance that could effectively kill bacteria while not being toxic to the body. The way Povidone-iodine works is actually quite interesting. The iodine works as an oxidizing agent. Oxidizing agents reduce the amount of electrons in an atom making something called an iodine-ion. An iodine-ion is what forms when a molecule is oxidized. It is an electrolyte that disturbs the balance of ions in a cell. This reaction results in the death

four groups of information sources: personal‚ commercial‚ public and experiential sources. The estate agent would form the commercial and public source of information‚ for example‚ while personal sources would be made up of family and friends. It stands to reason that information received from friends and family could be more convincing than the formal information received from the estate agent‚" says Goslett. But‚ he says‚ even though

oxidising agent and reducing agent. Oxidation and reduction in terms of oxygen transfer Definitions • Oxidation is gain of oxygen. • Reduction is loss of oxygen. For example‚ in the extraction of iron from its ore: [pic] Because both reduction and oxidation are going on side-by-side‚ this is known as a redox reaction. Oxidising and reducing agents An oxidising agent is substance which oxidises something else. In the above example‚ the iron(III) oxide is the oxidising agent. A reducing

To misquote Monty Python what have the Ancient Egyptians ever done for us? Well‚ they’ve given us cake for a start! Roman and Greek history records cake-making but according to food historians it’s the early Egyptians who were the first skilled bakers. We’ve come a long way from there; what the Egyptians – and even mediaeval Europeans – called cake wouldn’t be recognisable to us as such today. Although the Egyptians wouldn’t even have called it cake; that’s a word that has been used in

Determination of Iron by Reaction with Permanganate-A Redox Titration Purpose: The purpose of this experiment was to find the percentage of iron in an unknown iron oxide sample which could be determined through titration with a standard solution of potassium permanganate. Success in this analysis requires careful preparation and attention to detail. Performing this experiment also provides practice at titrations. The overall reaction is: 8H+(aq) + MnO4-(aq) + 5e- Mn2+(aq) + 4H2O Theory:
