Unfortunately, the thread you linked to is one that started and ended weeks before I came aBoard. I tried to click the link to the complete list, obviously it is much longer than the version I posted, but the link takes you to oblivion. Wish I could have read them, bet they were pretty funny.

It's an interesting testament to the fact that it's the WAY radiation does damage, not AMOUNT of energy, that is dangerous. You can figure it out for yourself if you're so inclined: This dose is 4 Gy = 4 J/kg. All you need is the weight of an average person (~70 kg), the heat capacity of water (4184 J/kg), and an estimate of the volume of a cup of water (0.25 kg). Presto! Edit: Ok, I calculated it. It's more like 0.27°C (0.46°F).

The male preying mantis cannot copulate while its head is attached to its body : "The juvenile sea squirt wanders through the sea searching for a suitable rock or hunk of coral to cling to and make its home for life. When it finds its spot and takes root it doesn’t need its brain any more so it eats it. It’s rather like getting tenure." -- Daniel Dennett, Consciousness Copy Link to Clipboard Share Post on Facebook Share Post on Twitter Page 2 of 2 1 2 Moderated by  Jackie  Hop To General Topics ------  Information and announcements  Q&A about words  Wordplay and fun  Words and languages in schools  Miscellany  Weekly Themes  Looking for (writers, speakers,...
