Great Pyramid of Giza

   The Great Pyramid of Giza (also known as the Pyramid of Khufu or the Pyramid of Cheops) is the oldest and largest of the three pyramids in the Giza Necropolis bordering what is now El Giza, Egypt. It is the oldest of the Seven Wonders of the Ancient World, and the only one to remain largely intact. Egyptologists believe that the pyramid was built as a tomb for fourth dynasty Egyptian Pharaoh Khufu (Cheops in Greek) over a 10 to 20-year period concluding around 2560 BCE. Initially at 146.5 meters (481 feet), the Great Pyramid was the tallest man-made structure in the world for over 3,800 years. Originally, the Great Pyramid was covered by casing stones that formed a smooth outer surface; what is seen today is the underlying core structure. Some of the casing stones that once covered the structure can still be seen around the base. There have been varying scientific and alternative theories about the Great Pyramid's construction techniques. Most accepted construction hypotheses are based on the idea that it was built by moving huge stones from a quarry and dragging and lifting them into place.

   There are three known chambers inside the Great Pyramid. The lowest chamber is cut into the bedrock upon which the pyramid was built and was unfinished. The so-called Queen's Chamber and King's Chamber are higher up within the pyramid structure. The Great Pyramid of Giza is the only pyramid in Egypt known to contain both ascending and descending passages. The main part of the Giza complex is a setting of buildings that included two mortuary temples in honor of Khufu (one close to the pyramid and one near the Nile), three smaller pyramids for Khufu's wives, an even smaller "satellite" pyramid, a raised causeway connecting the two temples, and small mastaba tombs surrounding the pyramid for nobles.

Amazon River

   The Amazon River in South America is the second longest river in the world and is by far the largest by water flow with an average discharge greater than the next seven largest rivers combined (not including Madeira and Rio Negro, which are tributaries of the Amazon). The Amazon, which has the largest drainage basin in the world, about 7,050,000 square kilometers (2,720,000 sq mi), accounts for approximately one-fifth of the world's total river flow. In fact, the river becomes biggest in the world even just entering Brazil, at only 1/5 of its final discharge into the Atlantic.

   In its upper stretches, above the confluence of the Rio Negro, the Amazon is called Solimões in Brazil; however, in Peru, Colombia and Ecuador, as well as the rest of the Spanish-speaking world, the river is generally called the Amazon downstream from the confluence of the Marañón and Ucayali rivers in Peru. The Ucayali-Apurímac river system is considered the main source of the Amazon, with as its main headstream the Carhuasanta glacial stream flowing off the Nevado Mismi Mountain.

   The width of the Amazon is between 1.6 and 10 kilometers (1.0 and 6.2 mi) at low stage but expands during the wet season to 48 kilometers (30 mi) or more. The river enters the Atlantic Ocean in a broad estuary about 240 kilometers (150 mi) wide. The mouth of the main stem is 80 kilometers (50 mi). Because of its vast dimensions, it is sometimes called The River Sea. The first bridge in the Amazon River system (over the Rio Negro) opened on 10 October 2010 near Manaus, Brazil.

Interview mistakes

5 interview mistakes you can easily avoid :-

    If you're interviewing for jobs, you know the feeling of kicking yourself for hours after an interview because you flubbed an answer or got the interviewer's name wrong. But no one is perfect, and most interviewers don't expect candidates to give perfect interviews.

    However, there are some interviewing mistakes that are easily avoidable, and which you can navigate away from with just a little bit of thought. Here are five interview mistakes that you can avoid if you know about them ahead of time.

1. Not preparing

    This is probably the No. 1 mistake most job candidates make: They show up for the interview without thoroughly preparing in the days before. Preparation doesn't mean a quick skim of the job description and a glance at the employer's website; it means at least several hours spent thinking through likely questions and practicing your answers to them, as well as thinking back on specific examples you can pull from your past to illustrate how you've excelled in previous jobs.

2. Not researching your interviewer

    A quick glance on LinkedIn might give you advance warning that your interviewer used to work with that old boss who hated you, meaning you won't be caught off guard if asked about it in the interview. Or simply reading your interviewer's bio on the company website might tip you off that she has a background in the software you used to work with and you might get a lot of questions on that.

3. Being late

    You might think that you're playing it safe by leaving for your interview a few minutes earlier than you need to. But hit a traffic accident and that buffer will fly out the window, which means you could end up arriving late. When you're heading out to an interview, it's smart to give yourself a huge buffer--meaning an hour or so--because it's nearly impossible to recover from being late for an interview. You can always kill the extra time in your car or a nearby coffee shop if you arrive early.

4. Wearing the wrong outfit

    In most industries, you should wear a suit to a job interview. (IT is sometimes, but not always, an exception.) It doesn't matter if your interviewers are more casually dressed themselves; wearing a suit, as the candidate, is still an expected convention typically. But aside from picking out the right clothes, you also need to make sure that you look polished and groomed--that your clothes fit you well, that your hair is neat and in place, that your makeup is professional and not heavy-handed. It's also key that you feel comfortable in whatever you're wearing; you don't want to be constantly adjusting your neckline or fidgeting with your cuffs.

5. Not being ready to talk about salary

    Job seekers are often more uncomfortable with conversations about salary than anything else, and as a result, they often don't prepare for how they'll handle questions about it. This is a huge disservice to yourself. If salary does come up and you try to wing it, you're likely to end up with less money in your offer than if you were prepared. So don't leave it to employers to manage salary discussions for you; do your research and thinking ahead of time so that you can field salary questions confidently.
