Relativity’s kin, the Bose-Einstein condensate, is 90 now
The BEC was Einstein’s last major prediction and it took a revolution in quantum optics to be realised. Continue reading

The intricacies of being sold on string theory
If you are seeking an appreciation for the techniques of string theory, then Brian Greene’s The Elegant Universe could be an optional supplement. If, on the other hand, you want to explore the epistemological backdrop against which string theory proclaimed its … Continue reading

Bohr and the breakaway from classical mechanics
One hundred years ago, Niels Bohr developed the Bohr model of the atom, where electrons go around a nucleus at the center like planets in the Solar System. The model and its implications brought a lot of clarity to the … Continue reading

How hard is it to violate Pauli’s exclusion principle?
A well-designed auditorium always has all its seats positioned on an inclined plane. Otherwise it wouldn’t be well-designed, would it? Anyway, this arrangement solves an important problem: It lets people sit anywhere they want to irrespective of their heights. It … Continue reading

The weakening measurement
Unlike the special theory of relativity that the superluminal-neutrinos fiasco sought to defy, Heisenberg’s uncertainty principle presents very few, and equally iffy, measurement techniques to stand verified. While both Einstein’s and Heisenberg’s foundations are close to fundamental truths, the uncertainty … Continue reading

The philosophies in physics
As a big week for physics comes up–a July 4 update by CERN on the search for the Higgs boson followed by ICHEP ’12 at Melbourne–I feel really anxious as a small-time proto-journalist and particle-physics-enthusiast. If CERN announces the discovery … Continue reading
