Author: Bronnie Ware For many years I worked in palliative care. My patients were those who had gone home to die. Some incredibly special times were shared. I was with them for the last three to twelve weeks of their lives. I learnt never to underestimate someone’s capacity for growth. When questioned about any regrets they had or anything they would do differently, common themes surfaced again and again. 1. It is very important to try and honour at least some of your dreams along the way. 2. By simplifying your lifestyle and making conscious choices along the way, it is possible to not need the income that you think you do. 3. We cannot control the reactions of others. 4. It is common for anyone in a busy lifestyle to let friendships slip. 5. Life is a choice.

Let us start by defining three descriptions of lift commonly used in textbooks and training manuals. The second description we will call the Popular Explanation which is based on the Bernoulli principle. The third description, which we are advocating here, we will call the Physical Description of lift. The popular explanation of lift Newton’s laws and lift Air has viscosity
Hacker Typer TextFugu 42 In The Hitchhiker’s Guide to the Galaxy by Douglas Adams, the number 42 is the “Answer to the Ultimate Question of Life, the Universe, and Everything”. But he didn’t say what the question was! Since today is Towel Day, let me reveal that now. If you try to get several regular polygons to meet snugly at a point in the plane, what’s the most sides any of the polygons can have? The picture shows an equilateral triangle, a regular heptagon and a regular 42-gon meeting snugly at a point. There are actually 10 solutions of with and each of them gives a way for three regular polygons to snugly meet at a point. But why is this so important? that make as close to 1 as possible, while still less than 1, the very best you can do is It comes within of equalling 1, since And why is this important? that has the maximum number of symmetries. and and you need for these triangles to fit on the hyperbolic plane. For example, if you take you get this tiling: symmetries. as small as possible! symmetries. It has Puzzles
