logs and log scales

give the eqn to calculate the no. of cells on agar at a certain time:

cells at time t = initial cells x 2^{(t/generation time)}

give an advantage of using log scales:

• to compare values with a large range of values

• allows more accurate reading off a graph

how do you convert from a log value to the normal value?

10^{whatever no you put in the brackets of log}

how do you read a log scale?

• one axis increases in a linear way

• the other axis has unevenly distributed lines - each represent a power of 10 (e.g. 1 ×10¹, 1× 10² etc.)

• (each marked increment on scale overlaps)
