im attempting to watch LOST now, so i'll be brief:
i need different dilutions of my milk samples. this site says that they should be in the quantities of 1:10, 1:100, 1:1000 etc. each dilution is grown in different petri dishes and agar plates.
after 2 or 3 days, the bacteria grows in colonies which appear as small spots on the agar plates. To find out how much bacteria is there i need to count the colonies & by doing this i will know the original amount of bacteria in the milk. so this involves some maths, but i have to research if there are easier ways of doing this or if this is the only one.
