Nearly every four years, we add an extra day to the calendar in the form of February 29, also known as Leap Day. Put simply, these additional 24 hours are built into the calendar to ensure that it stays in line with the EarthБs movement around the Sun. While the modern calendar contains 365 days, the actual time it takes for Earth to orbit its star is slightly longerБroughly 365. 2421 days. The difference might seem negligible, but over decades and centuries that missing quarter of a day per year can add up. To ensure consistency with the true astronomical year, it is necessary to periodically add in an extra day to make up the lost time and get the calendar back in synch with the heavens. The Egyptians were among the first to calculate the need for a leap year, but the practice didnБt
If youвve taken a lot of pictures, you might have noticed that the photos donвt always turn out the same as what we see. Why does that happen? Eyes and cameras both see images and they have a lot of mechanical similarities, but there are still many differences between them. Organic Aperture: The Iris Both eyes and cameras can control the amount of light passing through the lens. In our eyes, thatвs the job of the iris, which relaxes to contract the pupil, letting in less light, and flexes to expand it, letting in more light. In cameras, the aperture does something similar. Our Lenses Are More Flexible Than A Cameraвs One of the major differences between the way a camera functions and the way the eye does is that the lenses in our eyes can physically change shape in order to focus on
Congress is divided into two chambers, the Senate and the House of Representatives. The Senate is sometimes called the upper chamber and the House the lower chamber because the Founders thought that different sorts of people would be elected to these two bodies. House members face elections every two years in smaller districts, so the Founders thought that representatives would be closer to the people. In contrast, Senators were originally chosen by state legislatures, and with elections every six years and steeper eligibility requirements, the Founders believed that the Senate would serve as a voice for the nation's wealthy and established interests. To a certain extent, the Founders correctly predicted differences between the two chambers. ...
History suggests that the language of the nation with the most important military and such a lot guns is the only without doubt to grow to be the worldwide. History suggests that the language of the nation with the most important military and such a lot guns is the only without doubt to grow to be the worldwide language, and then its audio system will give an explanation for that the rationale is its good judgment and cosmetic. As an English speaker, and frequently ESL trainer, I m mindful of its flaws, ridiculous spelling and complicated phrasal verbs amongst others.

What is a Law? DonБt run with scissors in your hand! DonБt drive your car on the sidewalk! Do not steal your neighborБs property! How many times a day does someone tell you what to do? How often do you have to stop yourself from doing what you want, because you know that this action is prohibited or wrong? In the United States, it seems like we have laws, rules, and regulations to oversee just about everything. We donБt always like these rules, since they often mean that someone is telling us what to do, or keeping us from doing what we want. Yet to live in a civil society, we must have some rules to follow. Who gets to make these rules? Where do they come from? What happens when we break them? These are the questions this page will seek to answer for you. aws are rules that bind all

It's a simple and valid question: why should we be conserving energy? If you answered, "To save money! " you're not wrong. But conservation means much more than saving money, both at home and in the business world. We can conserve energy in many ways and at the many differently levels of energy consumption. At home, simple actions such as turning off the lights and unplugging computers or turning off televisions can help us reduce our consumption and thereby conserve energy. Installing thermostat technology is another means of saving energy and identifying the gadgets and appliances that are drawing power from the outlets even when not in use (more casually known as energy vampires). At the commercial level, updating older buildings with new, more efficient technology can help reduce the
Would you undergo heart surgery by a cardiovascular surgeon who had not passed his medical boards? Would your company entrust an accountant who was not a CPA to prepare and certify its federal tax return? These professions require mastery of a common body of knowledge that certifies proficiency. Yet we do not require the same of our young people. This keeps them from successfully competing not only nationally but globally. One path toward a solution that is gaining prominence is the controversial Б Common Core State Standards (CCSS). Adopted as part of the 2010 effort by the National Governors Association and Council of Chief State school officers to improve the nationБs competitiveness, the internationally benchmarked standards define the knowledge and skills students should gain

This is one area that really helps me to exploit my creative urges and gives a huge satisfaction when my designs are liked by people. I have therefore decided to go for professional degree in fashion designing so that I could further explore the intricacy of the business. I believe that the degree from this college would help me to grow not only as a person but also as a professional who would be able to meet the challenges of the contemporary world. My family and friends have been the major motivating force. My passion of ethnic design and use of fusion technique in my design is my strongest point. As a child I was much enamored with the fashion magazines which use to showcase the clothes of leading fashion designers of Milan and Paris. ...
