Estimating Large Numbers
Despite their importance in public discourse, numbers in the range of 1 million to 1 trillion are notoriously difficult to understand. We examine magnitude estimation by adult Americans when placing large numbers on a number line and when qualitatively evaluating descriptions of imaginary geopolitical scenarios. Prior theoretical conceptions predict a log-to-linear shift: People will either pla...
متن کاملEstimating Nielsen Numbers on Infrasolvmanifolds
A well-known lower bound for the number of xed points of a self-map f : X ?! X is the Nielsen number N(f). Unfortunately, the Nielsen number is diicult to calculate. The Lefschetz number L(f), on the other hand, is readily computable, but does not give a lower bound for the number of xed points. In this paper, we investigate conditions on the space X which guarantee either N(f) = jL(f)j or N(f)...
متن کاملEmbryonic lethals induced by x-iradiation of first meiotic metaphase oocytes of Habrobracon.
INVESTIGATIONS to be reported in this paper have been concerned chiefly whh X-ray-induced embryonic lethal mutations in Habrobracon. Some of the data and one of the methods have already been given (HEIDENTHAL 1952, 1953; HEIDENTHAL, C ARK and GOWEN 1955). The purpose of the author's work, as well as that of others, has been in part to study the frequency of different kinds of lethal-bearing gen...
متن کاملFrequency of "Cell-Lethals" among Lethals Obtained at Random in the X-Chromosome of Drosophila Melanogaster.
84 per cent albite and we know enough of relations in our general system (Fig. 1) to be able to say that the conditions are similar in mixtures with an excess of silica (simplified fayalite-rhyolites) and also in those with a deficiency of silica (simplified fayalite-phonolites). While we have made only a first step in the investigation of these extreme liquids it is plain from the results of t...
متن کاملThe Nature of Lethals in Drosophzla Wzllzstonz]
is well established that Mendelian populations carry a large amount of con‘:ealed variability. Chromosomes which are lethal when homozygous constitute an important part of the concealed variability in cross-breeding populations as shown, among others, by PAVAN et al. (1951) in Drosophila willistoni. Recessive lethal second chromosomes had a mean frequency of .286 in seven Brazilian populations ...
