Answer: computer programmer

Computer programmers need to be strong in logical thinking and attention to details, two things that autistic people with a normal or higher intelligence are good at. The other three professions can be hard for an autistic person because social interactions are important; they also can lead to a lot of stress, which is something many people with an autistic condition do not handle well.

Question by player Spaudrey

Answer: James Watt

James Watt was a Scottish mechanical engineer and inventor who lived from 1736 until 1819. He is most well known for his invention of the Watt steam engine which he developed in 1776 as an improvement upon other less sophisticated designs of others. When he needed to express in concrete images the amount of power his machine could produce, and based on earlier musings by one Thomas Savery in 1702, Watt calculated that one horse, during a day's work, could turn a large mill wheel around at the rate of 144 times per hour, which, based on the size of the wheel, equated to a horse travelling x number of feet per hour.

By then applying his estimated horse's pulling force (its power) at 180 lbs, he arrived at the amount of energy output per hour of the horse - as one horsepower.

Question by player Creedy

Answer: They become less frequent

A prime number is defined as a number that only has two divisors, itself and the number one. For example, 5 is prime as the only whole numbers between 1 and 5 that divide a whole number of times into 5 are 1 and 5. As you consider larger numbers, the average distance between prime numbers increases.

For example, 40% of the numbers 1-10 are prime, but only 25% of the numbers 1-100 carry the property, and less than 17% between 1-1000. This makes sense intuitively, as it is more difficult for larger numbers to be prime - they have to dodge all the numbers below them!
