Possibility

“…Physicists, for instance, do not stop searching for general laws when their initial attempts fail to produce the desired results. The same is true, for example, in computer science where "pessimism based on the failure of few, particularly simple, programming attempts is not taken seriously, and properly so" 31 . Thus, even if we grant that there have been some genuine theories of scientifi c change, it shouldn't preclude us from trying to construct a new TSC.…”

The Biennial as a Form of Contradiction: The 16th Biennale of Sydney, ‘Revolutions — Forms That Turn’

“…As was noted by Kelly in relation to the 1993 Whitney Biennial, it may be possible for critics to make a 'false choice' between art and politics predicated on a belief that art is either aesthetic and autonomous, or political. 66 Documenta 11 was criticised by some critics for privileging the 'political' over the artistic, while other critics saw its art as political but still functioning as 'art'. 67 Responding to such a situation, Christov-Bakargiev was able to explore what Kelly describes as the 'political autonomy' of art; a term intended to catalyse an exploration of the interrelationship of art and politics and the different ways that might be explored and embodied.…”

“…67 Responding to such a situation, Christov-Bakargiev was able to explore what Kelly describes as the 'political autonomy' of art; a term intended to catalyse an exploration of the interrelationship of art and politics and the different ways that might be explored and embodied. 68 Within her constellations Christov-Bakargiev related works that appeared to be more political in and of themselves with works that appeared more formally and aesthetically autonomous. 69 By relating them all to 'revolution', or what she described as perceptual 'forms of displacement', she ultimately embraced the politicality of artists' formal gestures without suggesting those artists are necessarily concerned with making 'political' art.…”

Documenting Ecological Change in Time and Space: The San Joaquin Valley of California

“…San Joaquin kangaroo rats however, appear to have largely disappeared from the valley floor, even from most of the larger parcels that remain uncultivated. Populations seem to be in a continuing decline, probably due to the combined effects of habitat conversion, fragmentation, degradation, and other factors (Chesemore and Rhodehamel, 1992;Williams and Kilburn, 1992;Williams and Germano, 1993;Goldingay et al, 1997;USFWS, 1998;Uptain et al, 1998;Kelly 2000). Populations in the more or less continuous band of grassland around the valley periphery are doing better but, even there, San Joaquin kangaroo rats are difficult to find.…”
