Which creates the interesting questions of:<p>1. Is da Vinci (or someone earlier) the inventor of the helicopter? Does invention include something working?<p>2. What is a computer? A calculator? Is the Antikythera a computer? Does it need to be Turing complete?<p>3. Didn&#x27;t hear about Babbage in 13y of German schools ;-) But then what are schools? Is university included in &quot;school&quot;?
