I can't wrap my head around this subject comfortably. I'm failiing miserably figuring out how to calculate population growth and isotope half-life.
Uni-level, but somehow I managed to forgot most about logarithms

just think of log(1) = 0. Then play around on your calculator and you can get all laws from there. Thats how I remembered to start with, back in ye olde high skool

Had the same problem until someone explained is this way:
Logarithm base 2 of 1 million = amount of times you can divide 1 million in two
like 1.000.000/2/2/2/2/2/2/2/2...
The way I think about it is, "This base to what power will give me the answer (that's already given)."
Once you grasp that, play around and find the rules.
Hint: Logarithms follow the same rules as dividing and multiplying exponents. (X2 • X3 = X^5)

khan and patrickjmt have so nice videos

I'm not a big fan of Khan, because of most of their videos are over 30min long, and half of it consist.

Look at it like this
Why can you search in logarithmic time in a sorted list?
If you have a dictionary(book) and you're looking for a word, you open the middle of the book, if the first letter of the word you are looking for is smaller then you open the middle of that left part, etc... until you find that word.
You keep dividing the book into two parts. This is logarithmic.
