Why must every brilliant idea already be taken?

An unsubstantiated fact got me thinking recently. If I remember correctly it concerned one of the Wesley's (18th century UK preachers). Apparently they made millions of dollars to support both evangelical ministries and the less fortunate through a shrewd method. As the preacher travelled between towns as part of his preaching ministry, he would have one of his aides read to him from the latest medical textbooks, which he would in turn summarise, simplify and publish for sale. This achieved both medical knowledge for the disadvantaged and made millions of dollars for new gospel and social initiatives.

What's my point? Apart from filling your mind with unsubstantiated facts, I wondered if I could do anything similar today. Not in the sense of summarising medical research for the masses - it's done already and there's probably some issues regarding plagiarism. But is there another need that I could meet with my limited skills and knowledge and make money off in order to give away? (I swear this isn't greed, as it would only ever work if every cent was given away.)

I thought I had it. Well, not really me, but Simone, here. I quote at length;

The trouble with reciples is that they focus on procedures instead of understanding.

I'd like a book that talked me through cake theory. What is the ratio of milk : eggs : butter : flour to make a general cake? How is a mud cake different? What effect is produced if you alter the flour/milk ratio? What ingredient is it that makes a cake richer? etc etc.

And what of biscuit theory, scone theory or slice theory? [I'm sure they're related.]

Turns out it already exists.

But before my ideas float off into the ether, I would like to share with you my titles for the first three chapters.

1. A cake that doesn't rise is a slice

2. What makes it pancake, and what makes it just a piece of crepe?

3. It's not undercooked, it's al dente

Happy 100th post!
