Pythagoras Bust

Socrates Bust
At the beginning of time, there wasn’t much to invent. Homo Sapiens had just become aware of the dangerous world it lived in and that he would need tools to survive the land. The very first inventions where the wheel, fire and “writing”, which by the time was just drawings that represented something. With the passing of time, Humans made weapons, boats and wooden houses. Many of those ideas weren’t assigned to a inventor until the time of Greece, when philosophers would record their contributions in books and other manuscripts. As it turns out, inventions pave the way so more inventions can be made faster or easier, such as Pythagoras(570/495 BC) many contributions to mathematics and Socrates(470/469 BC) vast contributions to the fields of science. Though, you may also have noticed that many of those scientists were pursued at the time for their “heretic” findings.

Leonardo Da Vinci
If we flash forward a couple centuries, we are now at 1450/1519 with a fellow named Leonardo Da Vinci, widely known artist for his many paintings and inventions that preceded his time in hundreds of years. What is also known, is that his inventions were many times taken as idiotic or simply too stupid to work, for the sheer fact they couldn’t test them at the time. He also contributed to many other fields of science, including natural science, mathematical studies and engineering. Now, we just have to leap a couple years to 1856/1943 to find another genius called Nikolas Tesla, a notable inventor, especially in the area of electricity and engineering, creating the Alternate Current, radio-controlled remote vehicles , induction motors and other advances.
Please take notice, that the further we go forward in time, the more advanced the discoveries become and the faster they occur. While we started with the Greek philosophers at around 500 BC, we had to make quite big leaps to effectively create other inventions, but when we come to 1000 AC forward, they start appearing in most fields at a much faster rate. This is due to how the writing, inventions and discoveries pile up from the past to the future creating a staircase where the new inventors can thread with more ease to reach for higher places.
