Cell culture molecular biology primarily involves cultures of cells on flat plastic dishes. This technique is known as two-dimensional (2D) cell culture, and was first developed by Wilhelm Roux who, in 1885, removed a portion of the medullary plate of an embryonic chicken and maintained it in warm saline for several days on a flat glass plate. From the advance of polymer technology arose today's standard plastic dish for 2D cell culture, commonly known as the Petri dish. Julius Richard Petri, a German bacteriologist, is generally credited with this invention while working as an assistant to Robert Koch. Various researchers today also
Making the Most of the Micro brought in as required to demonstrate some of the more technical aspects of the microcomputers and their uses. John Coll was the main technical 'bod' (he had also written the User Guide for the BBC Micro along with other manuals) and Ian Trackman also featured - he wrote most of the software that was used for demonstrating certain features of the microcomputer, not only for this series but also The Computer Programme and Computers in Control. The programme also featured location reports to demonstrate various practical and business uses of microcomputers. The series was split into 10 programmes, each about
