A Telangana Class IX SSC textbook, according to a Times of India report by Nirupa Vatyam, has cited late rockstars Freddie Mercury and David Bowie as “scientists”, crediting them with “removing salt from seawater using a semi-permeable membrane through a process called desalination”.

The goof-up in the biology textbook appeared in the “Did You Know” section, according to the report. Thomas Jefferson is considered the inventor of the earliest forms of desalination.
