10 Aug : Calculating time would not have been that easy

The Royal Greenwich Observatory or RGO foundation stone was laid today in london in 1675.

It has two major contributions to the navigation system.
1. The line that divides the earth into two hemisphere, the Prime Meridian is at the Royal Greenwich Observatory or RGO.

2. The observatory gave us a standardised method of measuring time.

Both these systems are quite technical, but at the same time very interesting. Indian Standard Time (IST) is 5 hours and 30 minutes ahead of Greenwich Mean Time (GMT).

The original cost of the Royal Observatory in 1675 was £520 i.e. ₹45281, which was actually £20 i.e. ₹1741 over-budget.

1675 में आज Royal Greenwich Observatory की स्थापना लंदन में हुई थी. Royal Greenwich Observatory का प्रयोग मुख्य रुप से navigation और खगोल विज्ञान के लिए किया जाता है. पूरी दुनिया को पूर्वी और पश्चिमी यानी दो हिस्सों में बांटने वाली prime meridian रेखा, इसी Royal Greenwich Observatory से  गुज़रती है.
