Vending Machine – 2nd c. BCE
Do you believe that until now, there are still millions of people in the world who have not seen and used a vending machine? And would you believe that as early as the 2nd century CE, vending machine was already invented by Hero of Alexandria. This engineer and mathematician invented a vending machine that accepted a coin and then dispensed a fixed amount of holy water. When the coin was deposited, it fell upon a pan attached to a lever. The lever opened up a valve which lets some water flow out. The pan continued to tilt with the weight of the coin until it fell off, at which point a counterweight would snap the lever back up and turn off the valve.
Compass -4th c. BCE
The compass had long been invented in China before the Europeans invented it. This significant invention, especially in navigation and exploration, was invented in the 4th century BCE in China. This gadget is a navigational instrument for determining direction relative to the Earth’s magnetic poles.
Odometer – 3rd c. BCE
This is quite unbelievable but the Odometer had long been invented a hundred years before vehicles powered by machines were invented. It was invented in the 3rd century BCE by Archimedes. An Odometer is a gadget that indicates distance travelled by a car or other vehicle.
Automatic Mechanical Calculator – 1623
The first automatic calculator was invented in 1623 by the German polymath Wilhelm Schickard.
Adding Machine – 1642
The first adding machine was invented in 1642 by Blaise Pascal.
Steam Power
Steam Power or Steam Engine was invented in the 2nd century by Hero of Alexandria in Roman Egypt. This invention is a heat engine that performs mechanical work using steam as its working fluid.
Wow, vending machine has been used for a long time. My mom owned an adding machine something like from your picture too. We just laughed about it because it's antique then we found out later it's a valuable collection.
ReplyDeleteI'm surprised by the vending machine since I felt it's something new but yes, if you use some levers, it's an easy device to construct. I'm familiar with the history of adding machine since we studied it in accounting.
ReplyDeleteVery much indeed surprised with these equipment..
ReplyDeleteI'm pleasantly surprised that these machines were invented way before the modern times especially the vending machine! This is why I love history!
ReplyDeleteVery Informative Papaleng, Additional knowledge.
ReplyDeleteThe adding machine and the automatic mechanical calculator is a must need for me if ever I live during the time they were first invented
ReplyDeleteI'm super proud I know all these even before I read your article! About those vendo machines, that's actually acceptable since there are some countries without access to it, some airports don't have those.
ReplyDeleteThese are cool machines Papaleng. The information is very appreciated.
ReplyDeleteWow. Those were really nice trivia and information. Wonder how much those machines worth now.
ReplyDeleteYou are so correct with the vending machine, I have never used one in my life. My kids uses it once in a while from school.
ReplyDeleteThe automatic calculator invented last 1623 looks totally cool. The thought of students bringing that size of a calculator daily nowadays is hilarious. :)
ReplyDeleteI don't know how to use a compass. Fun trivia!
ReplyDeleteWe should have more vending machines here so we can get stuff more conveniently and almost everywhere. I fancy vending machines in Spain and Japan since they contain products that we don't usually find.
ReplyDeletei'm surprised the vending machine has been out for so long! but then reading on the physics behind, it didn't seem to be so high-tech naman pala! hehe XD
