What a brilliant question! The first gymnasia go back to Ancient Greece and to Persia (known as Zurkhaneh, which roughly translates as "house of strength".)Japan has been known to have some form of physical education and training activity and spaces as far back as the 17th century while many a vyayamshala (Sanskrit, lit.
The first two-wheeled person powered conveyance was invented by a German nobleman in 1817. It was a bit more like a scooter you sat on, as didn't have pedals.

Wikipedia actually has a great page on this that's very well-researched.There's a chart with everything listed out, but it can be a little hard to read. Here's a summary of the most efficient ways to travel, with all the numbers converted into fuel consumption figures:Velomobile (4470 MPG, 0.053 L/100km)Electric Scooter (2000 MPG, 0.118 L/100km)Bicycle
How does one define "noble" as applied to an invention? The bicycle is a simple elegant machine that turns fuel we already consume - food - into power for transportation at a speed faster than walking or running. The mechanics are easy enough that most people can learn how
If someone invented a tracking device to put in every human so you know where they are what's would your opinion be?
My opinion is we already have them and they're called smartphones. We choose to have them.However one essential difference is that we can choose to take the batteries out, or turn them off or leave them at home (or send them on a wild goose chase with someone

Some modern riders might think that the push for ever more gears on the rear cluster from 5 to 6 to 7 and eventually to 10 and more is a recent phenomenon. In fact the ten speed lies at the mid-point between the earliest derailleur systems, invented some time around 1900, which had only

We don't actually know all that much about the development of the telescope. As Gwydion Madawc Williams points out, there are some references that suggest Thomas Digges built a telescope, but the references are vague.Now, what follows is only speculation, though
Short answer: -Ball bearings didn't exist, at least not good enough ones. Roller bearings are an old concept, but smooth, hard, uniform metal ball bearings didn't exist until the mid 1800's. Bicycles were actually one of their first major applications.-Chains weren't manufactured with high enough quality/precision/strength until ~1880's
Let's think about this.What is a light bulb? It's an electric lamp. Depending on the light bulb, how exactly it works differs; an incandescent light bulb works by the Joule effect, electrically heating a thin metal filament immersed in gas that prevents

As to which civilization invented the wheel it was likely Mesopotamia or was a culture that closely interacted on account that archeologists have found a wheel dated 5,500 years ago (3,500 BCE) within the walls of the ancient city of Ur.Interestingly the wheel that was found was not something to go on a wagon, or Chariot.

The answer to both of your questions is really ambiguous. Who invented dancing? Because dancing existed even in pre-historic times, it's impossible to find records of the very first person who danced. I would like to think, however, that the very first human would have danced.
