Iron Lady: The Eiffel Tower

Leaning to the left makes the Eiffel Tower seem smaller: posture-modulated estimation.

In two experiments, we investigated whether body posture influences people's estimation of quantities. According to the mental-number-line theory, people mentally represent numbers along a line with smaller numbers on the left and larger numbers on the right. We hypothesized that surreptitiously making people lean to the right or to the left would affect their quantitative estimates. Participan...

Model equations for the Eiffel Tower profile: historical perspective and new results

Model equations for the shape of the Eiffel Tower are investigated. One model purported to be based on Eiffel’s writing does not give a tower with the correct curvature. A second popular model not connected with Eiffel’s writings provides a fair approximation to the tower’s skyline profile of 29 contiguous panels. Reported here is a third model derived from Eiffel’s concern about wind loads on ...

Optimizations of Eiffel Programs: Smalleiffel, the GNU Eiffel Compiler

The design of the Eiffel language makes it possible to perform global optimizations on Eiffel programs. In this paper, we describe some of the techniques we used in SmallEiffel, The GNU Eiffel Compiler, to generate highly efficient executables for Eiffel programs. Most of these techniques — related to global analysis or not — may also be applied to other objectoriented languages.
