Mum sent me this so it has to be true – right? Here are some ‘facts’ about the 1500s: They used to use urine to tan animal skins, so families used to all pee in a pot & then once a day it was taken & sold to the tannery…….if you had to do this to survive you were “Piss Poor” But worse than that were the really poor folk who couldn’t even afford to buy a pot, they “didn’t have a pot to piss in” and were the lowest of the low.

Types of Mathematical Averages and Their Formulas In mathematics, the average of two or more numbers is called the mean. The most commonly used mean is called the arithmetic mean, in which you add up all the values and divide by the number of values. For example, the arithmetic mean of 2, 5, and 14 is (2+5+14)/3 = 7. However, there is more than one kind of mean, including the geomtric mean, harmonic mean, root mean square, and several others. The essential property of any mean is that it must fall between the highest value and the lowest value. Read These Seven Books, and You’ll be a Better Writer Donald Miller I used to play golf but I wasn’t very good. I rented a DVD, though, that taught me a better way to swing, and after watching it a few times and spending an hour or so practicing, I knocked ten strokes off my game. I can’t believe how much time I wasted when a simple DVD saved me years of frustration. I’d say something similar is true in my writing career.

The Hardest Logic Puzzle Ever The Hardest Logic Puzzle Ever is a logic puzzle invented by American philosopher and logician George Boolos and published in The Harvard Review of Philosophy in 1996. A translation in Italian was published earlier in the newspaper La Repubblica, under the title L'indovinello più difficile del mondo. The puzzle is inspired by Raymond Smullyan. It is stated as follows: Three gods A, B, and C are called, in no particular order, True, False, and Random. True always speaks truly, False always speaks falsely, but whether Random speaks truly or falsely is a completely random matter.

100 Very Cool Facts About The Human Body The Brain The human brain is the most complex and least understood part of the human anatomy. There may be a lot we don’t know, but here are a few interesting facts that we’ve got covered. Populations and Samples The study of statistics revolves around the study of data sets. This lesson describes two important types of data sets - populations and samples. Along the way, we introduce simple random sampling, the main method used in this tutorial to select samples. Population vs Sample Universal robotic gripper Robert Barker/University Photography The human hand is an amazing machine that can pick up, move and place objects easily, but for a robot, this "gripping" mechanism is a vexing challenge. Opting for simple elegance, researchers from Cornell, the University of Chicago and iRobot Corp. have created a versatile gripper using everyday ground coffee and a latex party balloon, bypassing traditional designs based on the human hand and fingers. They call it a universal gripper, as it conforms to the object it's grabbing, rather than being designed for particular objects, said Hod Lipson, Cornell associate professor of mechanical engineering and computer science. The research is a collaboration between the groups of Lipson, Heinrich Jaeger at the University of Chicago, and Chris Jones at iRobot.
