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...
متن کاملA Fresh Look at the Method of Archimedes
1. INTRODUCTION. A spectacular landmark in the history of mathematics was the discovery by Archimedes (287-212 B.C.) that the volume of a solid sphere is two-thirds the volume of the smallest cylinder that surrounds it, and that the surface area of the sphere is also two-thirds the total surface area of the same cylinder. Archime-des was so excited by this discovery that he wanted a sphere and ...
متن کاملThe so-called Stabilizer Theorem
Theorem 1.1 (Hrushovski’s Theorem 3.5). Let G be a definable group, X a definable subset, and G̃ be the ∨-definable group generated by X. Suppose all this data is defined over a model M . Suppose μ is an M-invariant translation-invariant ideal on subsets of G̃. Let q be a wide type over M , contained in G̃. Identify q with its ∧-definable set of realizations. Suppose (F) there exist two realizatio...

Hypertrophic emphysema is the most commonly used designation of this disease. Also, it is known under the following names: genuine emphysema, idiopathic emphysema, diffuse vesicular emphysema, obstructive emphysema, dystrophlc emphysema, pul...
