How Vacuum Cleaners Work

In its 100-year history, the electric vacuum cleaner has become an indispensable home appliance for most people, and it's obvious why. Imagine picking all this sawdust out of the carpet by hand! When you sip soda through a straw, you are utilizing the simplest of all suction mechanisms. Sucking the soda up causes a pressure drop between the bottom of the straw and the top of the straw. With greater fluid pressure at the bottom than the top, the soda is pushed up to your mouth. ­ This is the same basic mechanism at work in a vacuum cleaner, though the execution is a bit more complicated. In this article, we'll look inside a vacuum cleaner to find out how it puts suction to work when cleaning up the dust and debris in your house. As we'll see, the standard vacuum cleaner design is exceedingly simple, but it relies on a host of physical principles to clean effectively. It may look like a complicated machine, but the conventional vacuum cleaner is actually made up of only six e

How to Learn From Your Mistakes

No one is immune to making mistakes – we are human, after all! But if we simply apologize and carry on as before, we're in danger of repeating the same errors. When we don't learn from our mistakes, we inflict unnecessary stress on ourselves and on others, and we risk losing people's confidence and trust in us. In this article, we look at how to ensure that we take those lessons on board, and then use what we learn. How to Stop Repeating Mistakes Here are five steps to help you to learn from your mistakes, and to put what you discover into practice. Note: "Making a mistake" is not the same thing as "failing." A failure is  the result of  a wrong action, whereas a mistake usually  is  the wrong action.

The smallest country in the world

It may be difficult to imagine, but there is a country in the world smaller than New York City’s Central Park and one with a population smaller than a typical high-school class. Based on landmass, Vatican City is the smallest country in the world, measuring just 0.2 square miles, almost 120 times smaller than the island of Manhattan. Situated on the western bank of the Tiber River, Vatican City’s 2-mile border is landlocked by Italy. The official seat of the pope of the Catholic Church since 1377, Vatican City was not declared an independent state until the Lateran Treaty of 1929. After years of power struggles between popes and the political leaders of Italy over who could claim supreme authority in the region, Benito Mussolini and Pope Pius XI agreed to the Lateran Pacts on February 11, 1929, which created the independent state of Vatican City for the Catholic Church in exchange for the pope’s recognition of the Kingdom of Italy. Today, nearly 75 percent of the Vatican’s citizens are

Cesarean Section History

The history of caesarean section (C-section) dates back as far as Ancient Roman times. Pliny the Elder suggested that Julius Caesar was named after an ancestor who was born by C-section. During this era, the C-section procedure was used to save a baby from the womb of a mother who had died while giving birth. The mother of Julius Caesar himself, lived through childbirth, therefore eliminating the possibility that the ruler was himself born by C-section. Ancient Jewish literature from Maimonides suggests that the surgical delivery of a baby was possible without killing the mother, but the surgery was rarely performed. Survival rates would have been low after the procedure, due to the risk of bleeding and infection. Historically, the surgery has always been performed to save the baby rather than the mother. The first recorded case of a mother surviving the surgery was in the 1580s in Siegersausen, Switzerland where Jacob Nufer who was a pig gelder is said to have performed the operation
