Hi everyone! Thank you for taking a look on the forum at the Adelson illusion (Adelson 1993) shown in Figure 1 (left)! It created some great discussion that caused me to redraft the entire follow-up article! Indeed, we did couch the question differently than Edward Adelson. We asked the...

As all serious reef aquarium hobbyists know, light intensity is an important consideration for a successful captive reef. This short article will examine how light intensity decreases as water depth increases in an aquarium the depth often maintained by hobbyists. The Swedish researcher Nils...
