This recording shows an interactive discussion of the true need for discovery. Engineering innovation is pivotal to success, but should efforts be focused directly on solving the grand challenges that face humanity or can we afford pure innovation in the pursuit of theoretical beauty? With expensive and high profile projects such as the Large Hadron Collider (LHC) at CERN, Bloodhound SSC and numerous satellite launches, the UK is committed to exploration towards future technology, but can the resultant benefit be quantified? Can we put a price-tag on knowledge gain and how will this affect the engineers and scientists of the future?
