There also seems to be SiC sigma (SiC == silicon carbide): "SiC Sigma fibres are commonly used as reinforcement in metal matrix composites." That's the first sentence of the abstract of: <http://www.gruppofrattura.it/ocs/index.php/esis/ECF13/paper/viewFile/8615/5049> How does sigma relate to scriptum? One is Greek and the other Latin, for example. | | The rafter tables on my framing square were referred to as sic sigma. | It's a set of tables by which oblique and other angles which which are | used to join wooden members in a hip and valley roof may be | calculated. Interesting. I found no google hits on this usage. Of course now there will be: this list is visible to google.
