pivot of man‟s quest for sustainable

development (health, education, nutrition,

construction, communication, agriculture,

commerce, energy, defense etc.).

• S&T enhance our understanding of the

socio-economic, political, cultural,

environmental and even religious problems

of our country while technology is

necessary in solving these problems.

Page 7: Plenary paper presented by Professor Abiodun Ayodele at ...

Science/Technology/Sustainable Development

• Science is the process of discovery and the

relentless pursuit of increased

understanding through experimentation,

data taking, conjecture and modeling, and

critical testing of the boundaries of

knowledge – always seeking the true facts.
