I've just been shifting around various bits of equipment and computers in our 2nd and 3rd year physics lab, to make way for an item that's shifting in there from a nearby lab. It's gone something like this...(rising in semitones, with apologies to the original performers)
Da power socket is connected to da extension cord;
Da extension cord is connected to da monitor;
Da monitor is connected to da computer;
da computer is connected to da control box;
da control box is connected to da MRI machine;
da MRI machine is connected to da MRI-machine stand;
da MRI-stand is connected to da floor*;
Now why are there so many cables?
Dem cables, dem cables, dem power cables;
dem cables, dem cables, dem ethernet cables;
dem cables, dem cables, dem USB cables;
What a mess of knitting! [Roll on wireless power transmission!]
*The MRI-stand is connected to the floor because we don't want the thing to move. The unit is calibrated for the position it's currently in; I'm not inclinded to move it in a hurry. The other things, however, might be more sensibly located.
