In Search of the Castaways (Les Enfants du capitaine Grant, The Children of Captain Grant) is Jules Verne's 1865–1868 three-volume adventure novel about a search along the 37th parallel south for the shipwrecked Captain Grant.
In Search of the Castaways (1962 film)
In Search of the Castaways is a 1962 Disney adventure film directed by Robert Stevenson, starring Maurice Chevalier and Hayley Mills as searchers for a shipwrecked captain.
In Search of the Supernatural
In Search of the Supernatural (搜神记) is a collection of tales of spirits and strange events by Gan Bao, the model of the zhiguai genre.
In Search of Walid Masoud
In Search of Walid Masoud (al-Baḥth ʿan Walid Masʿūd) is a 1978 Arabic novel by the Palestinian writer Jabra Ibrahim Jabra about a Palestinian intellectual in Baghdad who vanishes.
In Search of... (TV series)
In Search of... is a syndicated American documentary series (1977–1982, 144 episodes) hosted by Leonard Nimoy that investigated mysteries such as Bigfoot, the Bermuda Triangle, and UFOs; revived in 2018 with Zachary Quinto on History.
In silico
In silico (Latin for "in silicon") describes experiments performed by computer or computer simulation rather than in living organisms (in vivo) or the laboratory (in vitro), first used in 1989.
In situ
In situ, Latin for "in place" (opposite: ex situ), entered English in 1740 and means in the natural or original position; used in archaeology, law, medicine, and laboratory science for on-site measurement.
In situ alloying in powder bed fusion
In situ alloying in powder bed fusion is an additive manufacturing approach where a part's alloy forms in the melt pool by melting blended elemental powders during printing.
In situ chemical oxidation
In situ chemical oxidation (ISCO) is a groundwater remediation method that injects oxidants such as permanganate, persulfate, hydrogen peroxide, or ozone to destroy organic contaminants in place, without excavation.
In situ crystallization
In situ crystallization is a laboratory technique in which crystals are grown and probed by diffraction or spectroscopy inside the reaction mixture, capturing transient phases invisible to ex situ methods.
In situ electron microscopy
In situ electron microscopy images materials in a gas or liquid, or while heat, electrical bias, or force is applied, instead of after the fact under vacuum.
In situ hybridization
In situ hybridization (ISH), including FISH, CISH, and RNAscope, localizes DNA or RNA sequences in cells and tissue using labeled complementary probes; devised by Gall and Pardue in 1969, now central to diagnostics and spatial transcriptomics.
In situ infrared spectroscopy
In situ infrared spectroscopy measures infrared absorption or reflection spectra of a material under reaction conditions, identifying adsorbed reactants and intermediates on working catalysts and electrodes; with simultaneous product analysis it is called operando spectroscopy.
In situ polymerization
In situ polymerization is a chemical synthesis method in which monomers polymerize directly inside a matrix, mold, or device, letting low-viscosity monomer wet fibers and pores before solidifying.
In situ preservation and reburial
In situ preservation and reburial is a conservation strategy protecting archaeological sites, especially underwater cultural heritage, in place; Article 2.5 of UNESCO's 2001 Convention makes it the first option.
In situ Raman spectroscopy
In situ Raman spectroscopy measures Raman scattering from a material while it operates inside an electrochemical cell, tracking electrode transformations during battery cycling and reaction intermediates on working electrocatalysts.
In situ simulation
In situ simulation is a healthcare training method that runs realistic clinical scenarios in the actual patient care environment with on-shift staff, exposing latent safety threats before they harm a patient.
In situ transesterification
In situ transesterification, also called direct transesterification, is a biodiesel production method that converts lipid-bearing biomass such as wet microalgae directly to fatty acid alkyl esters, skipping the separate oil-extraction step.
In situ transmission electron microscopy
In situ transmission electron microscopy images a specimen inside a transmission electron microscope while heat, gas, liquid, or strain is applied, recording changes as they happen.
In situ U–Pb dating
In situ U–Pb dating is a microanalytical geochronology method that dates zircon and other minerals in place, by laser ablation or ion microprobe, preserving their petrographic setting.
In situ X-ray absorption spectroscopy
In situ X-ray absorption spectroscopy (XAS) measures a material's X-ray absorption spectrum while it operates under realistic reaction, temperature, pressure, or electrochemical conditions, tracking oxidation state and local atomic structure.
In situ X-ray computed tomography
In situ X-ray computed tomography reconstructs 3D images of a sample from X-ray radiographs while it is loaded, heated, or operated, tracking internal structural evolution over time.
In situ X-ray diffraction
In situ X-ray diffraction (XRD) records X-ray scattering patterns from a material while it is heated, charged, reacted, or compressed, tracking structural change in real time.
In So Kweon
In So Kweon (권인소) is a South Korean computer vision researcher, professor emeritus at KAIST and head of KIST's Center for Physical AI Research from 2026.
In Space, No One...
"In Space, No One..." is episode 5 of Alien: Earth, FX's Alien franchise TV series, written and directed by Noah Hawley. Aired September 2, 2025; a 64-minute standalone flashback aboard the Maginot, unlike the series' Earth storyline.
In Spite of the Strong Wind (纵有疾风起)
In Spite of the Strong Wind (纵有疾风起) is a 2023 Chinese urban emotional drama directed by Fei Zhenxiang, starring Jin Dong and Song Jia, about PR executive Tang Chen rebuilding his career after betrayal by his fiancée Shuo Bing.
In Stars and Time
In Stars and Time (ISAT) is a 2023 turn-based time-loop RPG by insertdisc5 (Adrienne Bazir), published by Armor Games Studios for PC, Switch, PS4, PS5; Siffrin's party relives two days fighting King in Vaugarde.
In Su Lee
In Su Lee (이인수) is a South Korean materials chemist at POSTECH since 2011, known for silica nanoreactors controlling nanocrystal formation and for tiling silica onto living cells.
In Switzerland
"In Switzerland" (Polish: W Szwajcarii) is a love poem by the Polish Romantic poet Juliusz Słowacki, written between 1835 and 1838 and published in Paris in 1839.
In the Aeroplane Over the Sea
In the Aeroplane Over the Sea, Neutral Milk Hotel's second album (Merge, February 10, 1998), produced by Robert Schneider and inspired by Anne Frank's diary, became a cult classic after a lukewarm 1998 reception.
