Tenth Birthday, Third Editor

Weight at third birthday related to birth weight, duration of gestation, and birth order.

It is now well recognized that the weight ofchildren during the first few years of life is closely related to their weight at birth. This point has been made by Illingworth in a number of publications (Illingworth, 1939 and 1950; Illingworth, Harvey, and Gin, 1949; Illingworth, Harvey and Jowett, 1950), and has been confirmed recently by Parfit (1951) and by Norval, Kennedy, and Berkson (1951)....

Tight labor markets in many parts of the region appeared to limit job growth, particularly in the large trade and services sectors. A slumping cattle industry also curbed overall growth in parts of the district. Nonetheless, construction conti...

Tenth Prairie Analysis Seminar

If we have a real vector field in the plane, the integral curves foliate the plane. Similarly, if we have a complex vector field in C then the complex integral curves foliate space by Riemann surfaces. An example of a question one might ask, is whether these Riemann surfaces are dense in space. In the case of vector fields in the plane, this is impossible, but if we do it on a torus instead, it...

Cheryl's Birthday

We present four logic puzzles and after that their solutions. Joseph Yeo designed Cheryl’s Birthday. Mike Hartley came up with a novel solution for One Hundred Prisoners and a Light Bulb. Jonathan Welton designed A Blind Guess and Abby’s Birthday.
