China unveils “Beidou Navigation Satellite System (BDS)” in Asia-Pacific

image China launched Beidou Navigation Satellite System (BDS), a kind of global positioning system, in the Asia-Pacific from its Beidou satellite network with an aim to gain up to 20 % of global market share by 2015.

What would it do?

The system would initially provide positioning, navigation, timing and short-message services in China and the Asia-Pacific region. It is compatible with other global positioning systems and could provide positioning accuracy of 10 metres, velocity accuracy of 0.2 metres per second and one-way timing accuracy of 50 nanoseconds. It would provide both open and authorized global navigation services worldwide by 2020 and will eventually use 35 satellites.

Ramanujan’s mysterious deathbed Theory proven correct

image A cryptic deathbed theory given by India’s mathematics genius Srinivasa Ramanujan, has now been proven correct and it could also explain the behavior of black holes.

In 1920, when Ramanujan was on his death-bed, he wrote a letter to his mentor, English mathematician G.H.Hardy describing several new mathematical functions never before heard of, along with an intuition about how they worked.

In his letter, he described several new functions that behaved differently from known theta functions, or modular forms, and yet was very similar to them.

He hypothesized that his mock modular forms corresponded to the ordinary modular forms earlier identified by Carl Jacobi, and that both would wind up with similar outputs for roots of 1.

As per recent findings by American researchers, the formula is correct and could explain the behavior of black holes.
