The thing is he wasn’t making his free throws and the Clippers still won.Defending hack-a-DJClippers coach Doc Rivers talked quite a bit about the hack-a-DJ tactic. He asked reporters in the postgame news conference what they think about it. One reporter replied, “It stinks,” and everyone seemed to agree.For his part, Popovich is just taking advantage of the rules of the game. Or the lack of a rule that would prevent teams from doing it.“It is a rule,” Popovich said. “I hate it. I hate doing it. But it’s a rule. Free throws are part of the game. It is a whole lot better than chasing Chris Paul around all day.”Spurs future Hall of Fame forward Tim Duncan had his coach’s back.“Unless it gets outlawed, it’s part of basketball,” Duncan said. “If he (Jordan) starts shooting better, people will stop doing it. But until then, it’s basketball strategy. It worked for us. It gave us an opportunity. Unfortunately … we couldn’t sustain our offense enough.”This and thatThe Clippers were fifth in the Western Conference standings following Thursday’s victory. … The Kings (18-34 before Friday’s game against Boston) have no shot at the playoffs, but they do have All-Star DeMarcus Cousins on their roster. The 6-foot-11 post is averaging 23.8 points and 12.5 rebounds. … Former Clippers guard Darren Collison is averaging 16.1 points and 5.6 assists. Try to tell Clippers guard Chris Paul that center DeAndre Jordan is not a terrific player, and he might punch you right in the mouth. Not really, of course, but you won’t find a bigger supporter of Jordan than Paul.It was late Thursday night and the Clippers had just defeated the San Antonio Spurs 119-115 at Staples Center to win their third game in four without the injured Blake Griffin. Paul was asked about Jordan, who once again had to deal with the ridiculous hack-a-DJ ploy, this time utilized by coach Gregg Popovich.Jordan managed to make just 10 of 28 from the free-throw line, but he still scored 26 points with 18 rebounds and three steals. Paul was amazed, but not surprised.“I tell people all the time that he is one of the most under-appreciated people in the league,” said Paul, whose team plays host to the Sacramento Kings on Saturday at 7 p.m. at Staples Center. “I think the biggest thing, when we talked at halftime, I told him, ‘We have been together for four years now and that fouling thing is a sign of respect.’ “It is one of the only ways you can stop him, or try. He did not let that faze him. He kept rebounding, he kept playing. He is unbelievable.”Jordan’s free-throw percentage this season is down to 40.8. Believe it or not, that’s not his worst. Jordan actually shot just 38.5 percent in his rookie season in 2008-09, 37.5 percent the following season and 38.6 percent in 2012-13. He shot a career-best 52.5 percent in 2011-12. He’s shooting 42.2 percent for his career.At one point Thursday, midway through the fourth quarter, Jordan got a bit miffed when Aron Baynes fouled him on purpose near mid-court. Jordan kind of pushed Baynes away, with Baynes wearing a perplexed look. Otherwise, Jordan kept his cool rather well.“They were trying to foul me early and the refs were not calling it,” Jordan said. “I guess they wanted to make it known that they were fouling me. It is something that teams are going to use as strategy to slow us down and to get me mentally frustrated.“But over the years, it has become something that I have gotten used to. As long as we are getting stops and making (free throws), it doesn’t really matter.” Newsroom GuidelinesNews TipsContact UsReport an Error
Newly-released State papers have revealed several hidden stories from 1981 including fears that the Russians were looking at Rockall, an outcrop off Donegal, as a possible Cold War base!The outcrop – 250 miles off Donegal – is claimed by Ireland, Britain, Denmark and Iceland!The Irish Intelligence Service (G2) believed that the USSR would try to seize the rock and use it for an underwater missile base. Ireland, however, was more interested in the threat to Irish summertime from an EEC proposal to synchronise clocks across Europe.© 2011 donegaldaily.com, all Rights ReservedThe copying, republication or redistribution of donegaldaily.com Content, including by framing or similar means, is expressly prohibited by law.

One unintended effect of the U.S. federal shutdown is that helpful press officers at government labs are not available to provide a reality check to some of the wilder stories that can catch fire on the Internet. They would have come in handy this week, when a number of outlets jumped on a report on the BBC News website. The National Ignition Facility (NIF) at Lawrence Livermore National Laboratory in California, it reported, had passed a “nuclear fusion milestone.” NIF uses the world’s highest energy laser system to crush tiny pellets containing a form of hydrogen fuel to enormous temperature and pressure. The aim is to get the hydrogen nuclei to fuse together into helium atoms, releasing energy.The BBC story reported that during one experiment last month, “the amount of energy released through the fusion reaction exceeded the amount of energy being absorbed by the fuel – the first time this had been achieved at any fusion facility in the world.” This prompted a rush of even more effusive headlines proclaiming the “fusion breakthrough.” As no doubt NIF’s press officers would have told reporters, the experiment in question certainly shows important progress, but it is not the breakthrough everyone is hoping for.A memo sent out on 29 September to collaborating labs from NIF Director Ed Moses—which has been seen by Science—describes a fusion shot that took place at 5:15 a.m. on 28 September. It produced 5×1015 neutrons, 75% more than any previous shot. Neutrons are a product of fusion reactions, so they are used as a measure of success.Sign up for our daily newsletterGet more great content like this delivered right to you!Country *AfghanistanAland IslandsAlbaniaAlgeriaAndorraAngolaAnguillaAntarcticaAntigua and BarbudaArgentinaArmeniaArubaAustraliaAustriaAzerbaijanBahamasBahrainBangladeshBarbadosBelarusBelgiumBelizeBeninBermudaBhutanBolivia, Plurinational State ofBonaire, Sint Eustatius and SabaBosnia and HerzegovinaBotswanaBouvet IslandBrazilBritish Indian Ocean TerritoryBrunei DarussalamBulgariaBurkina FasoBurundiCambodiaCameroonCanadaCape VerdeCayman IslandsCentral African RepublicChadChileChinaChristmas IslandCocos (Keeling) IslandsColombiaComorosCongoCongo, The Democratic Republic of theCook IslandsCosta RicaCote D’IvoireCroatiaCubaCuraçaoCyprusCzech RepublicDenmarkDjiboutiDominicaDominican RepublicEcuadorEgyptEl SalvadorEquatorial GuineaEritreaEstoniaEthiopiaFalkland Islands (Malvinas)Faroe IslandsFijiFinlandFranceFrench GuianaFrench PolynesiaFrench Southern TerritoriesGabonGambiaGeorgiaGermanyGhanaGibraltarGreeceGreenlandGrenadaGuadeloupeGuatemalaGuernseyGuineaGuinea-BissauGuyanaHaitiHeard Island and Mcdonald IslandsHoly See (Vatican City State)HondurasHong KongHungaryIcelandIndiaIndonesiaIran, Islamic Republic ofIraqIrelandIsle of ManIsraelItalyJamaicaJapanJerseyJordanKazakhstanKenyaKiribatiKorea, Democratic People’s Republic ofKorea, Republic ofKuwaitKyrgyzstanLao People’s Democratic RepublicLatviaLebanonLesothoLiberiaLibyan Arab JamahiriyaLiechtensteinLithuaniaLuxembourgMacaoMacedonia, The Former Yugoslav Republic ofMadagascarMalawiMalaysiaMaldivesMaliMaltaMartiniqueMauritaniaMauritiusMayotteMexicoMoldova, Republic ofMonacoMongoliaMontenegroMontserratMoroccoMozambiqueMyanmarNamibiaNauruNepalNetherlandsNew CaledoniaNew ZealandNicaraguaNigerNigeriaNiueNorfolk IslandNorwayOmanPakistanPalestinianPanamaPapua New GuineaParaguayPeruPhilippinesPitcairnPolandPortugalQatarReunionRomaniaRussian FederationRWANDASaint Barthélemy Saint Helena, Ascension and Tristan da CunhaSaint Kitts and NevisSaint LuciaSaint Martin (French part)Saint Pierre and MiquelonSaint Vincent and the GrenadinesSamoaSan MarinoSao Tome and PrincipeSaudi ArabiaSenegalSerbiaSeychellesSierra LeoneSingaporeSint Maarten (Dutch part)SlovakiaSloveniaSolomon IslandsSomaliaSouth AfricaSouth Georgia and the South Sandwich IslandsSouth SudanSpainSri LankaSudanSurinameSvalbard and Jan MayenSwazilandSwedenSwitzerlandSyrian Arab RepublicTaiwanTajikistanTanzania, United Republic ofThailandTimor-LesteTogoTokelauTongaTrinidad and TobagoTunisiaTurkeyTurkmenistanTurks and Caicos IslandsTuvaluUgandaUkraineUnited Arab EmiratesUnited KingdomUnited StatesUruguayUzbekistanVanuatuVenezuela, Bolivarian Republic ofVietnamVirgin Islands, BritishWallis and FutunaWestern SaharaYemenZambiaZimbabweI also wish to receive emails from AAAS/Science and Science advertisers, including information on products, services and special offers which may include but are not limited to news, careers information & upcoming events.Required fields are included by an asterisk(*)For fusion experiments, NIF directs 192 laser beams from all directions at the fusion target in a pulse that carries 1.8 million joules (MJ) of energy. The outer part of the target is a tiny metal can the size of a pencil eraser, called a hohlraum, at the center of which sits a plastic sphere smaller than a peppercorn containing frozen fusion fuel—a mixture of the hydrogen isotopes deuterium and tritium, known as DT. The ultraviolet beams are fired into the hohlraum through holes at each end but not directly at the fuel capsule. Instead they hit the inner walls of the hohlraum, heating it so much that it emits a pulse of x-rays. The x-rays cause the plastic capsule to explode, driving the fuel inward toward its center.If all goes according to plan, the fuel—compressed to 100 times the density of lead—will ignite a fusion reaction, but the laser-driven implosion does not provide enough energy to burn all the DT fuel. Some energy from the fusion reactions is needed to keep the burn going. DT fusion reactions produce two products: helium nuclei (aka alpha particles), which carry 20% of the reaction energy as kinetic energy; and neutrons, which carry the rest. For fusion to work as an energy source, the alpha particles must efficiently heat up the fuel to keep the reaction running.To achieve this, NIF researchers have been experimenting with the shape of the laser pulse to make it deliver more power near the beginning. In his 29 September memo, Moses says these improvements had led to alpha-particle heating that doubled the energy yield—”a clear demonstration of the mechanism that is needed to achieve ignition,” he wrote. Ignition is the goal of a self-sustaining, alpha-heated fusion burn producing more energy than the laser put in. Moses also says the energy yield (carried by the neutrons and estimated at 14 kilojoules) was more than the x-ray energy absorbed to implode the capsule, a milestone he refers to as “scientific breakeven.”“It is a good experiment,” says Michael Campbell, a former director of NIF who now works for Logos Technologies in Fairfax, Virginia. “From a science standpoint, the target worked well enough for alpha particles to heat some of the fuel.” But Campbell is concerned about overhyping each step in what is bound to be a long haul toward fusion as an energy source. The energy yield in last month’s experiment is still a very long way from ignition, the goal—enshrined in NIF’s name—that the facility was expected to reach a year ago. NIF is now partway through a 3-year campaign to nail down why it is struggling to reach that goal. “It’s a science-based program now. They are trying to identify some of the obstacles to getting to ignition,” Campbell says.One requirement for ignition is that energy output should exceed the energy input from the laser, i.e., that gain (output divided by input) should be greater than 1. NIF’s laser input of 1.8 MJ is roughly the same as the kinetic energy of a 2-tonne truck traveling at 160 km/h (100 miles/h). The output of the reaction—14 kJ—is equivalent to the kinetic energy of a baseball traveling at half that speed. Numerically speaking, the gain is 0.0077. The experiment “is a good and necessary step, but there is a long way to go before you have energy for mankind,” Campbell says.
