Biography assessment rating comment[edit]

The article may be improved by following the WikiProject Biography 11 easy steps to producing at least a B article. -- Edofedinburgh 01:16, 24 March 2007 (UTC)[reply]

Inconsistency of units[edit]

In the second paragraph under Work is: " ... a 27-inch (69 centimeters) ... sculpture ... In 2010, ... the Umbilic Torus SC, a massive 8.5 meter-high ... sculpture ... the torus has a 7.7 meter ... " i.e. Imperial (metric), metric, metric. This inconsistency just makes life difficult for the reader. I have modified the paragraph to show metric dimensions (followed by Imperial in parentheses).
" ... the Umbilic Torus SC, a massive 8.5 meter-high ... sculpture weighing more than nine tons." Given that the height is metric, is the reader to assume that the weight is also metric (if so, tonnes, not tons)? Or is the weight in US short tons (9 being equal to 8.16 tonnes)?

Robot arm[edit]

"Ferguson wrote a program consisting of 25,000 movements to control a 16-by-20 robot arm and its affixed foot-long industrial diamond-encrusted cutting tool." Given that the cutting tool was 1' long, is the reader to assume that the robot arm was 16' x 20'? Or was it 16" x 20"? Or 16 m x 20 m? I favour 4.9 m (16') x 6.1 m (20') - but others may have better knowledge. Prisoner of Zenda (talk) 04:48, 24 October 2021 (UTC)[reply]

On p.21 of the PDF doc (https://archive.bridgesmathart.org/2012/bridges2012-17.pdf) about the construction is this: "The framework for this gantry robot has a footprint of sixteen feet by twenty feet." Solved. Prisoner of Zenda (talk) 05:02, 24 October 2021 (UTC)[reply]
