Host Brian Forbes returns after a stay in hospital and interviews Sir Reginald Bo-Hey No about his controversial book on creationism and evolution. Pith-e Productions. Written and performed by David Beeler and Tom Konkle. Invention is a creative process. An open and curious mind allows an inventor to see beyond what is known. Seeing a new possibility, a new connection or relationship can spark an invention. Inventive thinking frequently involves combining concepts or elements from different realms that would not normally be put together. Sometimes inventors disregard the boundaries between distinctly separate territories or fields. Ways of thinking, materials, processes or tools from one realm are used as no one else has imagined in a different realm. Play can lead to invention. Childhood curiosity, experimentation, and imagination can develop one's play instinct—an inner need according to Carl Jung. Inventors feel the need to play with things that interest them, and to explore, and this internal drive brings about novel creations. Thomas Edison: "I never did a day's work in my life, it was all fun". Inventing can also be an obsession. To invent is to see anew. Inventors often envision a new idea, seeing it in their mind's eye. New ideas can arise when the conscious mind turns away from the subject or problem; or when the focus is on something else; or even while relaxing or sleeping. A novel idea may come in a flash - a Eureka! moment. For example, after years of working to figure out the general theory of relativity, the solution came to Einstein suddenly in a dream "like a giant die making an indelible impress, a huge map of the universe outlined itself in one clear vision". Inventions can also be accidental, such as in the case of polytetrafluoroethylene (Teflon). In November 2006, escort and masseur Mike Jones alleged that Haggard had paid him to engage in sex with him for three years and had also purchased and used crystal methamphetamine. A few days later Haggard resigned from all of his leadership positions. After the scandal was publicized, Haggard entered three weeks of intensive counseling, overseen by four ministers. In February 2007, one of those ministers, Tim Ralph, said that Haggard "is completely heterosexual."Ralph later said he meant that therapy "gave Ted the tools to help to embrace his heterosexual side." On June 1, 2010 Haggard announced that he intended to start a new church in Colorado Springs. In February 2011, Haggard came out as bisexual. Intelligent design is the proposition that "certain features of the universe and of living things are best explained by an intelligent cause, not an undirected process such as natural selection." It is neo-creationism, a form of creationism restated in non-religious terms. It is also a contemporary adaptation of the traditional teleological argument for the existence of God, but one that deliberately avoids specifying the nature or identity of the intelligent designer. Its leading proponents—all of whom are associated with the Discovery Institute, a politically conservative think tank—believe the designer to be the Christian God. Evolution (also known as biological or organic evolution) is the change over time in one or more inherited traits found in populations of organisms. Inherited traits are particular distinguishing characteristics, including anatomical, biochemical or behavioural characteristics, that are passed on from one generation to the next. Evolution may occur when there is variation of inherited traits within a population. The major sources of such variation are mutation, genetic recombination and gene flow. Evolution has led to the diversification of all living organisms from a common ancestor, which are described by Charles Darwin as "endless forms most beautiful and most wonderful". There are four common mechanisms of evolution. The first mechanism is natural selection, a process in which there is differential survival and/or reproduction of organisms that differ in one or more inherited traits. A second mechanism is genetic drift, a process in which there are random changes to the proportions of two or more inherited traits within a population. A third mechanism is mutation, which is a permanent change in a DNA sequence. Finally, the fourth mechanism is gene flow, which is the incorporation of genes from one population into another Less
