Ancient India provided many useful inventions that are still used today. These are some of the most common inventions of Ancient India that are still used world wide today.
India began making steel as early as 300 BC. This was a very important advancement that is still used today. Of course the method in which it is done has become a lot easier and a lot less physically involved, but all together this was an amazing invention for ancient times. The steel was made by using wrought iron, charcoal and glass. They were mixed and heated until the iron melted and began absorbing the carbon. This was done by hand at that time. Currently, it is done almost completely by machine. However, if it were not for ancient India, who knows how it would have started.
Ancient India was the home of the first marine dock. It was located out of the strong current so it would not affect silt deposits. It was used to both build ships, and to repair them. It was used to load and unload passengers as well. This dock was constructed in 2400 BC and was located in the then town of Lothal.
The earliest known version of the saddle stirrup came about in 500 BC. It was considered a toe stirrup. This stirrup consisted of a rope with a loop at the end that held the big toe. This as great for the India climate, it was hot and most people rode their horses barefoot. Over time, and with different season change, the idea spread and developed into the foot grip stirrup we have today.
Law of signs in multiplication
Multiplication, as we all know today would not be the same if it were not for ancient India. Ancient India understood the meaning of debit and having a negative number. They understood that if you did not have any money and you owed someone $45 you had -$45. Over time, this was a concept that spread to the Arab countries, and was then passed on to Europe.
As early as 6,000 AD, Indian doctors were preforming cataract surgery. The tool that was used was called the Jabamukhi Salaka. It was a curved metal needle that was pushed into the eye, and used to push the cataract out of the patient’s vision. The eye was then soaked in butter and bandaged. This was only preformed when necessary.
