With respect to life, the origin of homochirality on Earth has been the greatest mystery because life cannot exist without molecular asymmetry. Many scientists have proposed several possible hypotheses to answer this long-standing L-D question. Previously, Martin Gardner raised the question about mirror symmetry and broken mirror symmetry in terms of the homochirality question in his monographs (1964 and 1990). Possible scenarios for the L-D issue can be categorized into (i) Earth and exoterrestrial origins, (ii) by-chance and necessity mechanisms, and (iii) mirror-symmetrical and non-mirror-symmetrical forces as physical and chemical origins. These scenarios should involve further great amplification mechanisms, enabling a pure L- or D-world.supramolecular assemblyweak neutral currenthomochiral and heterochiral aggregatesvortexneutrinosSoai reactionViedma ripening effectnucleus–molecular couplingabsolute asymmetric synthesiscircular dichroismenantiomer self-disproportionationmagmatic flowmetal-organic frameworkZ0 bosonhidden chiralitygravitationSDEetch figuresreplicatorssupramolecular chiralityderacemizationassembliesspin polarized electronssuper-high-velocity impacthomochiralitychirogenesisheat capacitytunnelingprebioticSalam hypothesistilt-chiralityself-assemblyracemic fieldtriethylenediamine (DABCO) moleculesenvironmental chiralitybioorganic homochiralitypolymerenantioselective reactiontwo-fold helixorigin of lifebiological homochiralityparity violation in the weak interactionamino acidsmulti-point approximationmagnetismC1- and C2-symmetric catalystsspin-polarized leptonlipidchiral field (memory)Wallach’s ruleasymmetric autocatalysisplasma reactorcircularly polarized photonasymmetric reactionracemateenantiomorphismsymmetry breaking?-strandchiralitycircularly polarized lightcircularly polarized luminescenceautocatalysisamino acid handednessasymmetric synthesisprecision measurementnephelinechiral separationparity violationachiral stationary phasegenesis of life chiralityhigh dimensional chiralityFujiki Michiyaauth1324888BOOK9910367746203321Possible Scenarios for Homochirality on Earth3036443UNINA05143oam 2200529 450 991082863910332120170523091545.00-08-098267-0(OCoLC)868947509(MiFhGG)GVRL8DIV(EXLCZ)99255000000106475220140424d2013 uy 0engurun|---uuuuatxtrdacontentcrdamediacrrdacarrierAdvanced mechanics of composite materials and structural elements /Valery V.
