Remember the Star Trek computer? It's finally happening--with Wolfram|Alpha. Building on 25 years of development led by Stephen Wolfram, Wolfram|Alpha has rapidly become the world's definitive source for instant expert knowledge and computation.Across thousands of domains--with more continually added--Wolfram|Alpha uses its vast collection of algorithms and data to compute answers and generate reports for you.Parts of Wolfram|Alpha are used in the Apple Siri Assistant; this app gives you access to the full power of the Wolfram|Alpha computational knowledge engine. Domains covered by Wolfram|Alpha include:MATHEMATICSElementary MathNumbersPlottingAlgebraMatricesCalculusGeometryTrigonometryDiscrete MathNumber TheoryApplied MathLogic FunctionsDefinitionsSTATISTICS & DATA ANALYSISDescriptive StatisticsRegressionStatistical DistributionsProbabilityPHYSICSMechanicsElectricity & MagnetismOpticsThermodynamicsRelativityNuclear PhysicsQuantum PhysicsParticle PhysicsStatistical PhysicsAstrophysicsPhysical ConstantsCHEMISTRYElementsCompoundsIonsQuantitiesSolutionsReactionsChemical ThermodynamicsProtecting GroupsMATERIALSAlloysMineralsCrystallographyPlasticsWoodsBulk MaterialsENGINEERINGAcousticsAeronauticsElectric CircuitsFluid MechanicsSteam TablesPsychrometricsRefrigerationStructuresASTRONOMYStar ChartsAstronomical EventsPlanetsMoonsMinor PlanetsCometsSpace WeatherStarsPulsarsGalaxiesStar ClustersNebulaeAstrophysicsEARTH SCIENCEGeologyGeochronologyGeodesyEarthquakesTide DataAtmosphereClimateLIFE SCIENCESAnimals & PlantsDinosaursDNA Sequence LookupSNPsProteinsHuman, Mouse & Fruit Fly GenomesMetabolic PathwaysCOMPUTATIONAL SCIENCESCellular AutomataSubstitution SystemsTuring MachinesComputational ComplexityAlgebraic CodesFractalsMathematicaImage ProcessingUNITS & MEASURESConversionsComparisonsDimensional AnalysisIndustrial MeasuresBatteriesBulk MaterialsPaintDATES & TIMESDate ComputationsTime ZonesCalendarsHolidaysGeological TimeWEATHERCurrent & Historical WeatherForecastsWind ChillHurricanesCloudsClimatePLACES & GEOGRAPHYMapsProjectionsGeodesyNavigationDistancesGeomagnetismGeocodingCountriesCitiesElevation DataOceansLakesRiversIslandsMountainsPEOPLE & HISTORYPeopleGenealogyNamesOccupationsPolitical LeadersHistorical Events, Periods & CountriesHistorical Numerals & MoneyCULTURE & MEDIABooksPeriodicalsMoviesVideo GamesFictional CharactersMythologyTelevision Networks & ProgramsAwardsMUSICMusical NotesIntervalsChordsScalesAudio WaveformsInstrumentsSongsWORDS & LINGUISTICSWord PropertiesDictionary LookupWord PuzzlesAnagramsLanguagesDocument LengthMorse CodeSoundexNumber NamesSPORTS & GAMESFootballBaseballOlympicsStadiumsLotteriesCard GamesCOLORSColor Names & SystemsColor AdditionTemperaturesWavelengthsMONEY & FINANCEStock DataIndicesMutual FundsFuturesMortgagesPresent ValueCurrency ConversionTipsBondsDerivatives ValuationWagesSales TaxSOCIOECONOMIC DATADemographicsCountriesUS StatesUS CountiesCitiesEconomicsAgricultureEnergySalariesUnemploymentCost of LivingHealth CareHousingSocial StatisticsCrimeMilitaryReligionHEALTH & MEDICINEBody MeasurementsGrowth ChartsExerciseDiseasesMortality DataMedical Test DataTeethVisionDrug DataHospitalsFOOD & NUTRITIONFoodsDietaryReferencesEDUCATIONInternational EducationUniversitiesSchool DistrictsPublic SchoolsStandardized TestsORGANIZATIONSCompaniesHospitalsFoundationsInternational OrganizationsTRANSPORTATIONAirportsAirlinesAircraftFlight DataRoad TransportGasoline PricesBridgesTunnelsTidesTECHNOLOGICAL WORLDCommunicationsSatellitesSpace ProbesPhotographyBarcodesWEB & COMPUTER SYSTEMSWebsite DataIP LookupNotable ComputersData TransferPort NumberingString ProcessingHashingUnicode Lookup
