The Stone Tool - The PjProblemStrings

The group of *Hominids* (humanlike creatures) called *Homo Habilis* (able man) lived in East Africa about 2 million years ago. They invented the *stone tools, the first multipurpose tools*. There were no formal education systems at that time, yet these *Homo Habilis* were able to pose and solve (albeit minimally) perhaps the most important mathematical problem of humankind (the making of tools). In order words, unbeknownst to them, they were mathematicians posing and solving Pj Problems (see wrong views of mathematics).
**(a)** What Pj Problem was on the minds of Homo Habilis that led them to conceptualize the *stone tool*?
**(b)** Assume stone *containership* and *identity* to be given and the stones are laid out to be *toolified*. Sequence the PjProblemStrings from this point to the *toolification* of the stone.
**(c)** How much difference exist between the PjProblemStrings Sequence involved in the making of the ancient stone tool and a modern tool like the automobile?

**The strings**: Pj Problems S_{7}P_{3}A_{32} (*force - push*) and S_{7}P_{3}A_{31} (*force - pull*) are of interest.
**(a)** A tool to exert force (P_{3}A_{32} and P_{3}A_{31}) was on their minds. Homo Habilis though able were initially poor hunters because they were tooless. They ate plants fruits, roots and carcasses. They conceptualized digging up the roots and chopping the plants. These were the first functions of the stone tool when they invented it. They later used the stone tool to scoop out the meat of dead animals and to crape open bones for their marrow. Eventually, they weaponized these stone tools against animals and against themselves. Thus began the *arms race*.
**(b)** Containerships and Identities are assumed known. Pj Problems of interest reduce to the Pj Problems representing ** fetch**,

The *point* **.** is a mathematical abstraction. It has negligible size and a great sense of position. Consequently, it is front and center in abstract existential reasoning.
