how do you write the following by using an indirect proof?

if a triangle is not isosceles, then the measure of the median to any side of the triangle is greater than the measure of the altitude to that side.

I have read "Against the Gods: The Remarkable Story of Risk" by Peter Bernstein. I was wondering (for those who have read it as well) if you could recommend any other books of this type. i.e. Non-fictional treatment of mathematical / statistical / financial concepts.

A heap and its 1/7 part become 19. What is the heap?

Solution:
Assume 7
(Then) 1 (heap is) 7
(and) 1/7 (of the heap is) 1
(making a) Total 8
(But this is not the right answer, and therefore)
As many times as 8 must be multiplied to give 19, so many times 7 must be multiplied to give the required number.
The text then finds (by rather complicated arithmetic) the solution (7) x (19/8) = 16(5/8)

Today we would solve the problem by the equation

This question is run by the principle of proportionality.
But I cannot find out proportionlity in this question.

Running question by assuming 'sth' also seems to be strange for me. Can you help me?

I have a T/F question which says, "Justify your answer. For all positive real numbers x, log(x) > 0

How would I go about finding "all" instances of this, or is it generally assumed that finding *any* single instance of proof/disproof is enough? I already know that if x=1 this statement is false. Log(1) = 0 and 0 is not > 0. Is that enough?

I'm studying this alone in my own free time so any additional advice for studying this type of math is appreciated.
