Ancient Indian civilization have contributed significantly to our today’s understanding of various topics. One of the most prominent is the Indus valley civilization.

Contributions:-

1. Mathematics:-

• The people of Indus valley civilization used standard weight system and measuring scale.
• The bricks used for construction in the Indus Valley civilization were of different sizes, but the dimensions of all the bricks were in the
  ratio 4:2:1.

2. Town Planning:-

• Lower and Upper town:
  • A typical city would be split into two sections, with each one being protected differently.
  • The upper level was on a man-made hill, while the bottom level was on flat ground.

• Grid pattern:

The streets of MohenJo – Daro and Harappa were laid out in a grid pattern and ran from east to west.

3. Sanitation:-

• A Well-Established Drainage system:

1. There was a big drain that went across the front of each house, and the little drains in each house were connected to it.

So we can conclude that, Indus valley had and have played a prominent role for the development in various fields. If today’s society learns even 1% from the life of Harappans  it surely will be a giant leap for India’s infrastructural and social growth.
