the shooting of a scene‚ we are able to view the scene playing in the background simultaneously. Besides storage capacity and interactivity‚ high-definition is another reason why Blu-ray is better; a blue-violet laser (405nm) has a shorter wavelength than a red laser (650nm)‚ hence the laser spot is able to focus with greater precision. Compared to DVDs‚ which only supports standard-definition (SD)‚ Blu-ray supports HDTV and offers five times more detail in the clarity and sharpness of picture‚ and

Landing project on Europa‚ the moon of Jupiter 1. Introduction This essay is aiming to present a feasible proposal for landing onto the Europa‚ which is the second closest moon to Jupiter. In human being’s history‚ the efforts and explorations of looking for extraterrestrial life never stops‚ from the moon to Mars‚ from the Voyager 1 and 2 which carry with human being information‚ to Galileo mission launched in 1989 and recently Curiosity rover. After investigated numerous data and

Storage Functions of secondary storage Secondary storage also called auxiliary storage or backing storage is used to store data and instructions when they are not being processed. Secondary storage is much cheaper than primary storage and is also used to back up for later use. Storage media Storage media are the physical hardware on which a computer keeps data‚ instructions and information. E.g. a CD‚ a DVD‚ a floppy disk‚ hard disk.

United States (U.S.) in the most efficient manner? Will the risk factors to the American populace be at a minimum? I believe the U.S. needs to commit to developing the best terrestrial-based laser possible. The advantages presented by this type of weapon far outweigh those of space-based lasers. I will discuss the advantages of both space and terrestrial-based missile defense systems in detail at an appropriate point within this paper. During the 1950s the Cold War ignited the arms

When John came home from the tattoo parlor with his brand new ink his parents were both infuriated. John’s parents are two world renown cosmetic surgeons‚ who deal with patients who have regretted their decision to get a tattoo everyday. They know how painful it is to have them removed because of how the ink is injected into the dermis‚ which is the inner layer of the skin that contains blood vessels and nerve endings. This caused John to grow very nervous about his tattoo and he made the decision

They would then point the laser at the targets with out turning it on. When they thought the laser was on the target they would turn the laser on. The results were measured with a point system: 15 pts for the core‚ 10 points for the next

device for the next hundred years" Cal Christiansen. The interferometer can measure lengths of one half the wavelength of the light source being used. With a HeNe laser (Helium Neon) this length is 316.4nm‚ about 1/3 of a micron. The interferometer is able to measure very small distances by the interference produced between two lasers beams. With this degree of accuracy there are clearly many uses for this device including‚ measuring flatness‚ structural stress‚ and making linear measurements.
