Scientist Study On Whether Patterns | Technology World | Ep 46



off the coast of Chile in 1960 a wild and destructive tsunami caused the deaths of thousands of people the mostly unpredictable and devastating waves formed from ocean floor earthquakes move quickly across ocean this wiping out coastal towns with the improvement in computer simulation equipment scientists hope to better understand and predict the formation of ocean tsunamis images like this one are the result of high-tech equipment being used to monitor rapidly changing flower movements in the western Pacific scientists believe that extreme conditions like this flooding are not only the result of combined climatic conditions such as cloud activity radioactive transfer and temperature but the increase in world population and lifestyle large-scale observation programs are the key to understanding the elements that affect our weather English apple farmers in Kent have come up with an innovative way of increasing the value of their product by using appropriate logos which are stenciled onto the apples wax coating these apples have a Halloween logo stenciled on them for the coming season British petrol buyers now have the opportunity to buy their fuel online at a much cheaper right priceline.com has set up a bidding system whereby consumers bid the price they would like to pay for fuel and the neighborhood from which they want to collect it petrol stations control the bidding system with guidelines of a minimum purchase price per litre this odd-looking stainless-steel catamaran is the latest german invention designed to carry up to 12 passengers on the waterways of Norfolk Broads in East England the popular wetlands reserve attracts large numbers of tourists each year with an estimated 13,000 boats using its waterways x-rays have many sources and the scientists and equipment used to monitor x-rays in our own galaxy and galaxies far away have become so high-tech that the precise time location and type of x-ray can now be identified quickly black holes quasars neutron stars and other fascinating galactic objects are being studied with a far more reliable eye questions relating to the evolution of our own planet are being approached by studying the lifespan of other planets and stars in our solar system the monitoring understanding and prediction of global weather patterns are technical expensive and time-consuming the Department of Energy has dedicated years enormous amounts of financial assistance and teams of scientific manpower to develop simulated weather models the models are designed to simulate various weather patterns in order to further our understanding and levels of prediction climate models are extremely complex and technical however not nearly as complex or volatile as Mother Nature herself prediction of dramatic weather conditions such as widespread flooding and tornadoes still mystify our equipment and technology weather patterns are dramatically changing throughout our planet scientists believe this global change is partly because of the increase in our population and the intensity of the industrial environments in which we live as our lifestyles have changed so to have the instruments with which we record measure and observe whether we're measuring of rainfall used to be sufficient now the relationship between the water vapor radiation cloud mass atmospheric pressure ocean and land temperatures and many other elements requires constant observation in order to understand the volatility of weather the Department of Energy has established a number of programs over the years one established in 1989 called the atmospheric radiation measurement program specifically records climatic conditions in three testbed sites across the world the equipment used is a mixture of traditional instrumentation and new highly technical instruments the western Pacific Test Site is situated on and around the islands of menace and aru in Papua New Guinea a team of local workers monitors traditional equipment such as these barometers the team measures temperature rainfall direct Sun radiation and indirect whether balloons are sent into the air every three hours to record temperature atmospheric pressure water vapor and wind speed in addition to traditional equipment they employ the latest in observation and recording equipment such as this whole sky imager the whole sky imager for WSI has a unique fisheye lens that can see the whole sky across the horizon and takes a picture of the clouds and sky activity every 10 minutes the data are then transferred to a computer which is linked to storage computers in the data facility in the United States the ceilometer constantly measures the bottom altitude from above a laser beam is sent directly up into the sky and it measures how long it takes for the laser beam to be reflected back computers store the data and produce graphic timelines throughout the day and night the microwave water vapor radiometer also looks into the sky it measures water vapor and water droplets from the surface to the top of the atmosphere this instrument has remote sensors that put out a continuous data stream that measures wind speed wind direction and temperature other state-of-the-art equipment includes the millimeter cloud radar a raman lidar and the GI aircraft used for multiple research trips reaching high and sustainable altitudes unmanned air space vehicles or UAVs a remote control aircraft that were initially developed for military purposes in the Cold War the military donated the aircraft to be used for scientific research because they could stay in the air for long periods of time this is the only known way that measurements can be taken on a long continuous timeframe at altitudes of up to 22,000 feet yearly research program is organized with the assistance of global teams such as Naru 99 where teams from America Germany and Japan used their own equipment to monitor water vapor are established to modulate data by using various instruments and techniques scientists expect that with these ongoing procedures and research programs our changing weather conditions will be easier to predict and we will be able to better equip ourselves for its effects some 43,000 British petrol stations have signed up to the latest Internet opportunity which is offering cheaper petrol to buyers online with prices in London at eighty one point nine pence a litre or a dollar 40 in u.s. the British pay more for their fuel than any of their European counterparts not surprisingly within the first three weeks of the scheme British drivers who were keen for a bargain bought over two million gallons of fuel through a new online gasoline service called priceline.com following a popular American model drivers log in and register for a special fuel card the customer basically makes a bid for fuel they select how much petrol they want to buy and what they're willing to pay for it the internet site then gives them an option of service stations in their neighborhood in order to get their fuel they simply use a special petrol card supplied to them by the internet site the saving for this method is approximately four pence per litre but while the bidding system may offer a measure of choice to the consumer petrol retailers will not be accepting outrageously low offers on the website the petrol retailers set guides as to what price you should bid in order for your bid to be acceptable there are also special offers advertised by sponsors who propose even cheaper fuel if you by their product there is a 90-day window in which the customer is able to receive their prepaid fuel the incentive for the retailer being confirmed business for that period the service has become extremely popular in Britain because of its dense population and large numbers of petrol stations other European nations will have to wait until the end of next year for this service x-ray astronomy is a relatively new study which began after World War two obsolete v2 rockets were handed over to scientists for use in experiments in suborbital flight attached to these rockets were x-ray monitoring telescopes however much of the data returned was of little use to scientists due to the obscure optics x-rays and gamma rays are the two types of rays emitted from a variety of galactic sources the majority of x-rays and gamma rays are absorbed as they hit the Earth's atmosphere it was necessary for equipment to reach far beyond the Earth's atmosphere to accurately record data this is exactly what riccardo giacconi achieved in 1962 this rock had detected a bright light source coming from the Scorpius constellation high-tech equipment and x-ray telescopes have made it possible to increase our knowledge of x-ray sources the two primary types of galactic objects pertaining to x-ray and gamma-ray sources are active galactic nuclei and x-ray binaries active galactic nuclei are most probably powered by massive black holes and are also present in some x-ray binaries supernova explosions produce a hot expanding shell of x-ray material a supernova exists when the core of a star collapses exploding its outer shell what is left behind is of notable interest to x-ray astronomers hot gas is also a fundamental source of x-ray activity galaxies including our own Milky Way produce clouds of hot gas that some scientists believe have significant affinity to black holes all stars including our own Sun produce x-rays and there is a phenomenon called gamma-ray bursts which scientists are only recently focusing on using the Contin gamma-ray Observatory to detect data on these bursts on a daily basis quasars and neutron stars are also a particular interest to x-ray astronomers one quasar has the power of one trillion stars and neutron stars produce energy that is equivalent to 100,000 times that of the Sun for 30 million times that produced by a single bolt of lightning young stars emit thousands of times more x-rays than stars that are middle-aged x-rays from young stars canna radiates the surrounding disks an experience that is now suspected to transform the properties of these disks thus influencing the formation of planetary systems the interaction between exploding stars young stars black holes Suns quasars neutron stars and many more galactic sources is what interests most x-ray astronomers in the search to discover our own planets evolution we monitor the different types of galactic objects their age characteristics interactions and development to be able to understand the maturation of our own planet x-rays have many sources and the scientists and equipment used to monitor x-rays in our own galaxy and galaxies far away have become so high-tech that the precise time location and type of x-ray can now be identified quickly black holes quasars neutron stars and other fascinating galactic objects are being studied with a far more reliable eye questions relating to the evolution of our own planet are being approached by studying the life span of other planets and stars in our solar system low frequency acoustic signals from the atmosphere have been monitored since the 50s testing of nuclear weapons was the primary motive and the US Air Force was anxious to discover who was testing and just where this testing was occurring however the entire observation program was a top military secret in those days because the detection technology was hidden from the scientific community and comprehension of the data received was little to none the advancement of this technology was slowed considerably today we have infrasound monitors hydro acoustic sensors seismic sensors and radio nuclei sensors positioned across the globe to supervise any low frequency acoustic signals from atmospheric shallow buried or moderately shielded explosions what has been illuminated from this equipment is that there is an enormous amount of natural explosive activity going on in the atmosphere for instance meteors or fireballs entering the Earth's atmosphere produce sound waves equivalent to sonic for hypersonic booms these sound waves mimic manmade explosions determining the difference between the man-made and natural explosions with the help of digital technology is not difficult natural explosive activity can originate from a number of sources for instance in the wake of a volcanic Mountain turbulent shock waves are produced and discharged into the earth also in the ocean the interaction between waves and wind nano cyclone hurricane or tsunami propagates shockwaves through the atmosphere or the ocean floor sending detectable waves to the senses thoughts of lightning can also be detected the CTBT your comprehensive test-ban treaty is the non-proliferation monitoring of explosives this programme aims to use the four types of technology infrasound hydroacoustic seismic and radio nuclei simultaneously on earth in the ocean and in space to accurately supervise global activity the infrasound monitoring device houses an audio microphone that has been modified to respond to very low frequencies it uses a backing volume that allows for pressure to be equalized between the inside of the backing volume and the background atmosphere this determines how low the frequency or response can go the poorest hoses run as far as 50 feet away from the sensor in order to expand the surface detection area these hoses reduce the amount of wind turbulence allowing the sensor to pick up extremely low frequencies it is through these hoses that the sound travels and is directed into a pipe that leads directly to the microphone surface in the white dome the microphone consists of two disks and the packing volume the disks move closer together than apart like a capacitor in an electrical circuit this infrasound monitor is one of four in the area positioned at distances optimal for accurate supervision data is then sent to this recording outpost which in turn compiles the data from all four sensors and transmits it to a data center the CTBT will be a similar configuration however the equipment will be more advanced and finely tuned the data center in Florida will transmit information to an international data center in Austria where all information will be compiled and posted on the internet for public viewing the Norfolk Broads an age-old network of inland waterways situated in eastern England it is a magnet for visitors who flock to see the wildlife and enjoy the peace and quiet of this famous wetland area however with an estimated 13,000 boats going up and down the waterways ecologists are worried about water pollution and damage to the banks from diesel-powered craft this unusual craft could provide the alternative the waterways management team is seeking the vessel is called rar after the Egyptian Sun God it is the first solar-powered boat on the Broads commission from Germany by the Broads Authority it will ferry twelve passengers at a time silently and cleanly round the newly restored Barton broad from next spring the restoration of Barton broad has been going on for the past five years the shallow lake is now back to the clear attractive lake it used to be organizers are excited about the chance to continue the ecological management of the lake by using a boat that carefully whispers along powered by the Sun the design of the catamaran reduces the wash from the boat and therefore damage to the riverbanks is kept to a minimum the designers say it is a marriage of science and aesthetics the stainless steel body requires little maintenance unlike regular boats that require constant repainting two centuries after these windmills were built alternative energy is coming back to the Broads England gets as much light as Greece during the summer therefore there is no danger of the solar powered craft running out of fuel no it's not an unusual skin blemish and it's not a television trick these apples really are branded with an image the owner of this apple farm in Kent England fruit growing country has hit upon the idea of branding his apples for good business reasons the process is long and intensive however the Japanese farmers receive up to two pounds sterling an apple with this technique in May the apples are still quite small and the farmers cover them in double layered bags this helps to ripen them and has also claimed to intensify the flavor with this technique there is no need to spray the fruit with pesticides in September as the picking season approaches the outer bag is removed however the wax bag underneath stays on for a few more days the inner waxed bag protects the apples from the late summer Sun it too is stripped off after two or three days the white sheets on the ground here reflect sunlight which assists ripening at this point logo bearing stencils are rubbed onto the apples and left while they ripen this farmer hopes the eye-catching idea will promote English apples supermarkets have already tested the idea with their customers these apples are specifically aimed at the Halloween celebrations at a pound a time or a dollar fifty US apples with logos certainly need a special occasion for most people to buy them farming is going through a particularly hard time at the moment and innovative ideas like this only aid in increased profit it should all mean better quality apples with a little something extra on the skin to make you laugh the phenomenon we call tsunami is a series of travelling ocean waves of extremely long lengths generated by earthquakes occurring below or near the ocean floor underwater volcanic eruptions and landslides can also generate tsunamis in the deep of the ocean the wave length from crest to crest can be hundreds of miles yet the wave height there be only a few feet in these deep waters the waves can reach speeds of up to or exceeding 500 miles an hour as a tsunami reaches shallower coastal waters wave height can increase rapidly the energy is compressed into a much shorter distance creating destructive waves sometimes coastal waters are drawn out into the ocean just before the tsunami strikes unfortunately the mechanism behind tsunami generation is not well understood however scientists are able to numerically model tsunami generation open ocean propagation and coastal run up with the latest in computer technology about two-thirds of the earth is covered by the waters of the four oceans the Pacific Ocean is the world's largest covering more than one-third of the total surface area of our planet the Pacific Ocean is surrounded by a series of mountain chains deep ocean trenches and island arcs sometimes referred to as the Ring of Fire the great size of the Pacific Ocean and the large earthquakes associated with the Ring of Fire combined to produce deadly tsunamis in less than a day a large tsunami can travel from one side of the Pacific to the other with the improved simulation models pressure sensors on the seafloor and satellite and radio telemetry detection of tsunamis is slowly improving you
