Consequently, his research of the Earth’s age turned into calculation of ''"the correct sample ratios"'' from ''"observed ratios"'' so that the Table in his paper could finally show the “correct” preconceived age, established in this field of research.<ref name=GALE>{{cite web |title=U-Pb studies of the appley bridge meteorite |author=Gale, N.H., Arden, J. and Hutchison, R. |publisher=Nature Phys.
