Question: what do u think was the greatest invention by an engineer and who invented it

This is a hard question, but a good one!
For example, a really important invention was the wheel, but we don’t know who invented it.
Most important inventions started as rough experiments, and then gradually over time they got better and better. That is what engineers do: they often try to improve things. So it is hard to give the credit to one person. Think of the car, the aeroplane, the rocket, a computer, a mobile phone, the internet, … They have all gradually improved and evolved.
