virtual environment. In order for the user to enter the virtual reality world‚ the user puts on a special suit or gloves equipped with fiber-optic sensors. These fiber-optic sensors are able to interpret body positions. The user also wears special goggles that have video screens and audio attachments. This equipment allows for the user ’s complete immersion into a 3-D‚ computer generated‚ model of reality (Carr 37). The use of a two-way data transfer is what enables this interaction with an alternate

Detective Eliza Graham quickly read over the Police Report and proceeded to interrogate the first suspect – Jonathon Miller. He was an old‚ pudgy man with friendly eyes and a large‚ distinguishing nose. She could hardly see how this could be the man responsible for murder‚ but looks can be deceiving. ‘So‚’ the man said a little too cheerfully for Eliza’s liking. ‘Would you be able to tell me what all this—’ he waved a hand to the closed file Eliza was holding‚ ‘—is about?

Practical Report: Background Information: Hydrogen peroxide (H2O2) is a combination of hydrogen and oxygen. In high concentrations‚ it can be unstable and even poisonous. In lower concentrations‚ such as the types found in many homes‚ it works well as a disinfectant and antiseptic.The reason behind foaming of Hydrogen peroxide is because blood and cells contain an enzyme called catalase. Since a cut or scrape contains both blood and damaged cells‚ there is lots of catalase floating around.When

The Effect of temperature on beetroot This experiment is designed to investigate the effect of varying temperature (centigrade) on beetroot and its cells. My earlier experiment suggest that as temperature increases the integrity of the beetroot cell membrane will be destroyed and a subsequent release of beetroot pigment will be released into its surrounding milieu(in this case distilled water). In the experiment I will examine if my hypothesis (above) is correct. In order to conduct this experiment
