This tells how people have overcome what often appear to be impossible odds to help to create that world. There are tales of toil on a grand scale: monumental buildings and great cities, created by armies of labourers using few simple tools. The Pyramids and the Colosseum, built thousands of years ago, are imposing reminders of our predecessors' determination and vision. The 15th-century octagonal dome of Florence Cathedral remains one of the most complex pieces of architectural egineering ever attempted. More recently, engineers have cut mighty canals and laid railways accross continents. Their epic struggles to overcome all obstacles exemplify the human drive to succeed. There are also epic stories of single minded determination. Polynesian and Viking sailors crossed oceans in small boats, without navigational intruments. Hannibal took an army of elephants over the Alps, and Samurai dedicated their whole lives to learning the art of war. Scientists like Galileo and Darwin challenged the established order with their ideas. All such achievements are based on perseverance, intelligence and unshakable self-belief. The blog @iknowhow, is not solely concerned with the great breakthroughs in technology, art or thought. It also features the daily challenges which people have always had to meet: eating, keeping clean and getting dressed. How did people of the past light their homes at night, and how did they find out the date and the time? What did they do when they were ill, and how could they seek justice if they felt wronged? The answers to all these questions- and many more- are given in this vividly written reference blog, which the entire steemit community and steemians will find it very useful and imformative. Above all, @iknowhow brings the past to life as it charts the progress of civilization, saluting the unsung heroes and heroines as well as the geniuses behind the human story- from the time of the first hunters to the modern age. ![GifMeme16300402072017.gif](https://steemitimages.com/DQmZznHqqc3nQE4QnBN3SmMZGZxTxXfaU7gMJ6eVTug4Fue/GifMeme16300402072017.gif) Image taken from pixabay.com
