Communication (from Latin commūnicāre, meaning "to share") is the act of conveying intended meanings from one entity or group to another through the use of mutually understood signs and semiotic rules.
Language is a system that consists of the development, acquisition, maintenance and use of complex systems of communication, particularly the human ability to do so; and a language is any specific example of such a system.
Henry Drummond: Language is a poor enough means of communication. I think we should use all the words we've got. Besides, there are damned few words that anybody understands!
Inherit the Wind (1960 film), Jerome Lawrence and Robert Edwin Lee
Meeting the world's energy demands is one of the major challenges of our time. Renewables? Nuclear? Fracking? Carbon Capture and Storage? We're desperate to discover a silver bullet. Our researchers are exploring all possible solutions - from mathematical methodologies for adapting our systems to visionary, seemingly whacky, plans for future energy extraction.
