Debugging a FOURTH program 1992 era
The program is supposed to keep the pH in the fermentor at pH 7.10 the set point(local set point). As the Bacteria grow the pH begins to drop below the set point the controller will open a valve to a pressure vessel that contains Sodium Hydroxide 5N for a given periop of time. There is also a...- jlorda

Debugging a FOURTH program 1992 era
This is all we have to go on. We have been trying to get our hands on the documentation that came with this program. But that was probably gone long ago. F1U6.TXT is just the program. The dictionary file is F1U6parm this gives the variables for the program from what I can tell. This is all we...- jlorda

Debugging a FOURTH program 1992 era
I work at a Bio tech company in Ma. We manufacture a Feline Leukemia Virus vaccine. We currently use a TCS 6366 controller(1987 vintage) to control our pH in our 500 L fermenter. The 6366 controller has been giving us some erratic out puts. We would like to program another 6366 as a backup so...- jlorda

Graduate How close to light speed can you theoretically get?
Relativistic mass is just another name for the energy? according to Wikipedia. So we know that mass is an expression of energy from e=mc^2? So if an object has mass of 0 then 0 = E/c^2 = ? I am trying to make sense of this.- jlorda

Graduate How close to light speed can you theoretically get?
How can mass of an object be = to zero? How can the mass of an object be = to zero ? If mass is zero would it still exist? How can nothing be something? Does this mean that light can not be a particle ?- jlorda
