From RAJARAM NITYANANDA
The discovery of discotic liquid crystals at the Raman Research Institute
in India, mentioned in your article (‘The fourth state of matter’, 4 May),
was the joint work of three people – S. Chandrasekhar, B. K. Sadashiva,
and K. A. Suresh, who are in fact the authors of the original 1977 paper
‘Liquid crystals of disc-like molecules’ (Pramana, vol 9 p 471).
