The truth nothing but the truth... but not the whole truth!

I enjoy solving problems. Indeed it forms a central part of my professional business and of my personal identity. Hence I spend a significant proportion of my time getting ‘stuck’ or simply being confused. In the past my technology was a pencil and paper together with algebra calculus and where necessary tables of integrals and special functions. Currently when I am stuck I usually reach for more contemporary technology such as the dynamic environment of GeoGebra or a computer algebra system (CAS). This is what I mean when I talk about ‘technology’. Communications and collaboration data capture online journal access internet search and storage technology are key components of my practice but I don’t comment on these here.
