A New Look at the So-Called Trammel of Archimedes

1. INTRODUCTION. STANDARD TRAMMEL. Figure 1a shows a line segment of fixed length whose ends slide along two perpendicular axes. It can be realized physically as a sliding ladder or as a sliding door moving with its ends on two perpendicular tracks. During the motion, a fixed point on the segment traces an ellipse with one quarter of the ellipse in each quadrant (Figure 1b), so this device is c...

The So-called Rhythms of Growth-energy in Mouse Cancer

IN CONCLUSION WE MAY SUMMARIZE THE ABOVE BIOLOGICAL OBSERVATIONS IN A SERIES OF THESES AS FOLLOWS: 1. Cancer cells differ from other epithelial cells in respect to: (a) Size relations of nucleus and cell body; (b) power of indefinitely continued division. 2. Cancer cells differ from embryonic cells in absence of: (a) power of differentiation; (b) power of coördination of parts to whole; (c) pow...

A head called Richard

This paper describes two preliminary experiments concerned with the construction of a robot head. The initial design and research is aimed at producing a system with two cameras and two microphones on a system capable of operating with the same degrees of freedom and reflex times as its biological counterpart. Whilst the primary goal of the project is develop an anthropomorphic system with the ...
