The potential power of 'Software Patents' to destroy Crystallographic Software; Crystallographic Software Development; and Crystallography's Future. by Lachlan M. D. Cranswick - part of Software Patents Involving Crystallography - CCP14 Homepage
Many Software Patents patent the trivial, but describe their claims in complicated "patent speak". This can also help mask the patenting of an "idea", as though it was really a novel, non-trivial "invention".

Mothering Magazine -- Boredom The Cauldron of Creativity:
"Over the years, I moved reluctantly through boredom's idle territory. I would be a different person today without the paths that it delivered. For boredom often pressed me to say 'yes' to strange tasks and exotic foods. It nudged me to read extraordinary books, to take walks and talk to strangers. Boredom has volunteered me, sent me to foreign countries, and pushed me out of dead-end jobs. Boredom led me to believe that the only way forward is through. "
...
"When we respond to boredom's invitation, something magical happens. Passions are born. Interests are developed. An inner fund of resources evolves-the same personal resources that guide and prompt us into a meaningful life. Without this fund, boredom can push our children into self-destruction: drugs, violence, and random pranks that eat up their young lives and spit them out. We are left to pick up the pieces and wonder what went wrong.
We are rightfully fearful of boredom and its negative consequences. Too much time and money, little purpose, and boredom are a lethal combination. In an attempt to save our children, we sign them up for sports and classes. We let them watch a crazy amount of television and spend days at the computer.
I want to allow my children to be bored while they are young and under my watchful eye. To measure it into their bones and muscles like a rare fuel to propel them forward. To preempt the time spent on television and organized activities and have them spend it instead on claiming their imaginations. For in the end, that is all we have. If a thing cannot be imagined first-a cake, a relationship, a cure for AIDS-it cannot be.
Life is bound by what we can envision. I cannot plant imagination into my children. I can, however, provide an environment where their creativity is not just another mess to clean up but welcome evidence of grappling successfully with boredom. It is possible for boredom to deliver us to our best selves, the ones that long for risk and illumination and unspeakable beauty. If we sit still long enough, we may hear the call behind boredom. With practice, we may have the imagination to rise up from the emptiness and answer."

Quaternions were developed by William Rowan Hamilton around 1843 and immediately took their place in mathematical history as a solution in search of a problem.

Psychobiology of Boredom
Boredom may be defined as the suspension of intentionality, fidgety indifference, frustration, and painful estrangement from a reality experienced as meaningless. Normal boredom emerges in specific environmental situations (reactive boredom) and quickly dissolves (acute boredom), while pathological boredom, arising unrelated to external circumstances (endogenous boredom), becomes a pervasive and long-lasting cognitive-affective state (chronic boredom) and causes mental suffering as well as functional and social impairment. To overcome this painful condition, behavioral attempts (eg, making journeys, compulsive buying, gambling, nicotinism, or bulimia) and/or pharmacologic attempts (ie, substance abuse and dependence) are frequently made.
