European Stars And Stripes (Newspaper) - August 31, 1989, Darmstadt, Hesse Page 4 the stars and stripes thursday August 31.1989 researchers fake i past 7 by Ion digits task called useful for testing computers by the associated press in the world of mathematics Gregory and David Chudnovsky Ard known Tor going the extra mile. Unsatisfied with their record 600-mile-Long calculation of i in june the Brothers More than doubled that record coming up with a number containing More than a billion digits. They re starting More calculations so it goes on from Here Denis Arvay a spokesman for ism said tuesday. I Don t know when they re going to meanwhile six California scientists extended Man s search into the infinite by determining the world s largest known prime number. The find left Joel f. Smith one of the researchers groping for a Way to describe the 65,087-digit num Ber. It s god awful Large Smith said. There s Noth ing in the real universe that is comparable at All that you measure in those i the ratio Between the diameter and circumference of a Circle begins 3.14159, then continues on indefinitely with nol Cnown duplication or pattern. Since i was first approximated at 3.14 in ancient Greece it took centuries and the invention of the computer in recent decades for scientists to calculate the ratio to More than 100,000 Decimal places. But in less than three months the Chudnovsky extended their record calculation from 480 million Decimal places to More than a Columbia University researchers did their work on two supercomputers at International Busi Ness machines corp s Thomas. Watson research Center in Yorktown Heights n.y., the company new Mark of 1,011,196,691 digits appears to be a record Arvay Crnz associate Dir Cor of the mathematical association of America said he had not heard of anybody exceeding the researchers Mark. In june the Chudnovsky said their 480 million digit i would stretch for 600 Miles if printed. At the time David Chudnovsky said calculating i to such lengths is useful for testing the performance of computer hardware and software. He called the task the ultimate stress in California the six researchers at compute maker Amdahl corp. Spent evenings and weekends during the last year using the company s machines to find the largest prime number. The number equals 391,581 multiplied by two tothe 216,193rd Power minus one. To put that in perspective that s 600 times the number of atoms inthe known universe according to Sergio a Zaranto Ocllo one of the researchers. It s like going to the Moon in a sense. There s not a lot there but it s important scientifically to Doit because the technology proves so useful researcher Bodo Parady said. A prime number is any number that can be divided evenly Only by one and itself. According to the guinness Book of world re cords the previous record was set in i98s by David Slowinski of Cray research inc., the supercomputer maker. The new number discovered aug. 6, has 37more digits and is a trillion trillion trillion times larger. Sunnyvale Amdahl said guinness had accepted the number for entry into the Publica Tion. The discovery was announced at a meeting this week of the american mathematical society by Sam Wagstaff jr., a computer scientist at Purdue univer sity. Although the number itself has no known practical application the advanced multiplication programs honed by the researchers during their work already arc being used by scientists searching the universe for pulsars rotating Neutron stars. The process also has applications in cryptology and Bank transaction coding which use Large prime numbers. The other Amdahl researchers were John Brown Landon Curt Noll and Gene Ward Smith. Alabama bans waste shipments from Many states Montgomery Ala. A Ala Bama is Banning hazardous waste ship ments from 22 states and the District of Columbia to keep the state from be coming the waste dump of the nation gov. Guy Hunt said. A representative of the hazardous waste Industry said his group plans to Challenge the ban the second of its Type in the country in court. On tuesday the Alabama depart ment of environmental management identified states that Are affected by the Law enacted in May. The Law ban states from sending hazardous waste to Ala Bama if they Don t have some Means of disposal within their own Borders or if they Don t have a cooperative agreement with Alabama. The intent of this legis Latan was to Force states to accept responsibility for the hazardous waste they generate. In the past it has seemed Alabama was the path of least responsibility said sue Robertson chief of the department s land division. Alabama s ban is similar to one enacted earlier this year by South Carolina. Tucker Eskew an aide to South Caro Lina gov. Carroll Campbell applauded the move and said the two states Are aim ing for a regional approach which ensures reciprocity and fair Burden Shar ing in waste disposal. Richard Fortuna executive director of the hazardous waste treatment Council in Washington said the lobbying group has made overturning the two states Laws a top priority. He said the state Law violate Federal interstate Commerce stat utes and will cause a shortage of Hazar Dous waste Sites nationally. It is virtually certain we will Chal Lenge one. The Only question is whether we will Challenge both he said. Robertson said Alabama s ban would affect Only the hazardous waste Landfill at Emelle the nation s largest. The la leaves it up to the Landfill operator chemical waste management to Stop shipments from the banned Stales she said. Chemical waste spokesman Chri Grimshawe said the company is studying the list of states and will decide later whether to take Legal action. According to figures compiled by stat environmental officials Alabama ranks fourth in the amount of hazardous waste it collects from other states and second in net intake which deducts waste ship Ped out of the state. Indiana ranks first in both categories. Robertson predicted that the ban could reduce Emelle s waste by 50,000 to 100,000 tons for the rest of the the ban the department had predicted that the Landfill would receive700,000 tons of waste this year up from 550,000 tons last year officials from Alabama and seven other Southeastern states will meet thursday in Atlanta to discuss ways to dispose of hazardous wastes Over the next 20 years. Robertson said the ban could be used As a negotiating tool to get the other states to handle their share of the waste. South Carolina is the Only other Southeast state with a hazardous waste Landfill. Eighteen of the banned states and the District of Columbia have no disposal facilities. They Are Alaska Arizona Del aware Florida Iowa Kansas Maine Mississippi Missouri new Hampshire new Mexico North Carolina North Dakota South Dakota Vermont Virginia West Virginia and Wyoming. Idaho Montana Oregon and Washington also were banned because they did not respond to the state s request for information about hazardous waste disposal within their Borders. Japanese w. German firms pull ads from magazines War editions new York a japanese and West German companies that ordinarily advertise in weekly . Newsmagazine apparently Don t want their products associated with memories of Blitzkrieg Gas Chambers and death marches. Time Magazine and . News & world report said tuesday that some advertisers pulled ads out of their special issues on the 50th anniversary of the outbreak of world War ii. Time and . News declined to identify the advertisers. But the world War ii issues were noticeably lacking in ads from japanese companies which Are heavy advertisers in the magazines. Newsweek Magazine whose special War coverage was limited to slightly More than two pages of Book reviews in its sept. 4 Issue had a Normal amount of advertising from japanese companies in the Issue. West German companies do not advertise every week in any of the magazines so it is difficult to deter mine whether any had pulled ads. Some of the ads that were pulled were switched to other issues of the magazines said spokesmen for the magazines. The net of it was that we did lose some business time spokesman Brian Brown said. Spokesmen for Japan s t9ypta motor corp., Nissan motor co. Ltd s infiniti division and Honda motor co. Ltd s Acura division which frequently advertise in the magazines tuesday said their absence from the world War ii editions had nothing to do with the magazines contents. Newsweeklies often notify advertisers when the plan articles that might Embarrass them. For example if a Magazine is running a cover Story on alcoholism it would warn liquor companies. We make it very Clear that the Story is going to Runin any Case and 1 think that Speaks Well for editorial integrity Brown said. . News has a similar policy spokeswoman Beth Ksyniak said. It has no ads from japanese or West German companies in its aug. 28-Scpt. 4 double Issue featuring stories on world War ii.
