Maybe not the greatest invention but Air conditioning is pretty underrated. Comfort and food presevation. Concrete is pretty high on the list same with paved roads. ETA beat by warpiper |

The pill. No one likes to wear a raincoat while taking a shower.

yoga pants has to rank close to the top. View Quote No, no and furthermore..................NO!!! If the inventor had also installed a fail-safe device that prevented them from being worn by fat chicks and 80 year old skeletons then I might agree with you. But as it is.............NO!!! My vote is for internal combustion. |

Division of Labor...if that could be considered an human invention.

I'm not sure I can think of a specific invention, but man's utilization of electricity for practical purposes. The telegraph was probably the earliest invention (that I can think of) that used electricity on a wider scale for the first time.
ETA: I think I might change my answer to the printing press as another poster said. Without this invention man would not have had easy access to information that spurred on the knowledge necessary to create everything we have today, including my answer above. We wouldn't have been nearly as smart or knowledgeable without being able to teach what we know to as many people as possible like we can with modern printing presses -> MS Word. |

birth control, by managing births (no I am not talking about abortions but the pill, IUDs, rubbers, cervical caps, etc) the west has been able to increase it's wealth while keeping down the cost of families. You can see the growth of Britain as a economic powerhouse in the 19th century when they deliberately kept their population down to expand their wealth.

I don't think it is the wheel many North American civs did not have the wheel. Aztecs and Indians. Language and god. And yes man made god. And those civilizations never got past the stone age. Just random food for thought... Many people (mostly commoners) went straight from the stone age to the iron age due to the extraordinary cost of bronze, and the utter ease of manufacture (in comparison) of steel. Also, don't discount the sharpness or utility of stone tools, they're just very brittle! |

For SW Florida....central air. Without it this place would be unbearable in the summer and spring and fall.

It's the Thermos. Hands down and no discussion. You puts hot things in it and it keeps them hot. You put cold things in it and it keeps then cold. How do it know? How do it know?? |

If that pic is an A/C then THIS!!! The Haber-Bosch process. It is used to produce massive amounts of ammonia. This allowed the Germany's military to kill lots of people quickly and farmers to feed lots of people with the NH3 it produced. |

Iron, on the other hand, is easily cast. And stone tools are sharp. They put a lot of meat on the spit. But most of the advances in human civilization would not have been possible without the wheel. |

Written medium. From bone or wood tally sticks, to clay tablets, to paper, the written word was a way to store vast sums of knowledge and pass it on to future generations.

Plow. It allowed one to feed many and this allowed for expansion of other crafts since many didn't have to be farmers anymore.
