The logo is a single helix, a form representing a separated strand of DNA at the time of its replication. From the angle in which it is viewed, the helix forms the letter "M" for "Malayan."
The helix stands for biology, the H2O molecules for chemistry, the atoms for physics.
All of life can be represented by the 4 letters A,C,T and G - the bases of the DNA molecule: A for adenine, C for cytosine, T for thymine and G for guanine. These letters stand for biotechnology.
All information can be represented in 0’s and 1’s, the binary digits or bits. These represent information technology.
Altogether, the logo distills science and technology, the essence of the Malayan High School of Science!
