On the crest of the wave-front of any advancements is science, followed by research, followed by development, then engineering. - Science finds the new things - Research plays around with these things and susses out repeatable factors - Development sees if those repeatable factors can be turned into a product - Engineering builds those products (- and sales and marketing sells them)
