"I am the president of a small Missouri based corporation Accident Reconstruction Limited."
"[An accident reconstructionist] is someone who mathematically accesses, usually traffic accidents, and applies known formulas and physics laws to the occurrences that happened. And usually what it boils down to in the final draw is an assessment of time and distance on the sequence, or the events that occurred during the accident."
....
[The mathematical expert witness is asked to covert his own drawings to real units using his own scale. The problem is (3 + 3/16) * ~20 = 68. Calculator in hand, he has no idea how a scale works. In reality, he probably just measures these things and puts the numbers in a computer. So he has no idea if the computer is spitting back the correct information.]
....
"Are you capable of deriving any of these formulas?"
"Of deriving them? No sir. Not generally. We have been taught of how to look them up in the book. We have been taught in the use of them. But to break them down and derive them back to the square root and kinetic energy, no."
...
[The mathematical expert witness is then given the basic formula for applying a scale (multiplication). drawing * scale = answer. The mathematical expert then claims that he does not know how to multiply a fraction by 20 without a "formula sheet".]
