8 World-Renowned Inventions & Scientific Discoveries Made by Indians

India is considered to be one of the most ancient countries in the world, so it’s not surprising that it gave us countless genius inventions, and brilliant discoveries we’re using to this day. It’s safe to say that the human race would not be the same without India’s contributions.

Here are 8 world-renowned inventions and scientific discoveries made by Indians.

Earth’s orbit (700 AD)
Today every sane person knows that it takes Earth 365 days to make a full revolution around the Sun. What if I told you that Indian astronomers somehow already figured it out between 700 BC and 600 AD? The exact number they got was 365.2563627 days, which is only 1.4 seconds off, according to our modern calculations.

First ever dentists (7000 BC)
Nobody likes when their teeth are in bad condition, but up until 7000 BC, nobody seemed to know what to do with that pain. That’s when some dude from the Indus Valley Civilization came up with using bow drills to make the pain go away.

Ruler (2400 BC)
Right around the same time ivory rulers starting to appear in nowadays India. One of such rulers had 1/16 of an inch marks (under 2 millimeters). How else would they measure all those bricks?

Rotating spindle (500 AD)
Before the genius inventors from India figured out how to spin yarn easier and more efficiently 15 centuries ago, the entire world did it manually. That method was later called the Charkha, and became the symbol independence for millions of Indians.

First plastic surgeries (2000 BC)
Even 4000 years ago people were not okay with how they looked. The ancient masters used their skills to change the malleable human flesh. Almost 16 hundred years later, the Indian physician named Sushruta became the official father of plastic surgery, with books and scrolls full of his teachings later making their way to Europe.

Ayurveda (5000 BC)
Ayurveda originated in India long time ago. About 5000 BC, to be precise. It involves lots of herb-focused therapies, as well as munching of minerals and metals.

Flush toilets (2500 BC)
People of the Indus Valley Civilization have been flushing their poopies since at least 2500 BC! Nearly every home had a flush system installed.

Crucible steel (200BC)
Turns out that South India cracked the secret of creating high grade steel over 2000 years ago! While it took us Europeans another millennium or so.
