In a sense, the change of your upward acceleration can slow but you are still increasing your speed upward .. just less so than before.</div><div class=""><br class=""></div><div class="">Back then I was excited by the personal discovery from one of my studies that goats metabolised levamisole at twice the rate of sheep .. well it was exciting to me back then. I later caused some Monash Uni Faculty of Education researchers to scratch their heads with my M.Ed project by visualising my data this way (not by introducing them to sheep)</div><div class=""><br class=""></div><div class="">Frightening is to talk to a biologist about exponential growth. </div><div class=""><br class=""></div><div class="">Horror is to do the same with a climate scientist with the addition of a positive feedback loop.</div><div class=""><br class=""></div><div class="">True terror is to discover that your former year 12 class is now running the country.</div><div class=""><br class=""></div><div class="">Regards Roland</div><div class=""><div class=""><div class="">
