Newton observed the shape of the Earth to be oblate spheroidal or oval shaped, not prolate spheroidal or spherical. (According to Choi, 2007) • Giovanni Cassini, who discovered four moons of Saturn and estimated the distance between the Earth and Sun to be 87 million miles, maintained that the Earth was flat at the equator. His theory stirred controversy, contradicting Newton’s and others who maintained that the Earth was flattened at the poles. (Burns, 2001, p. 55) What are some discoveries and

establish a reference point by building a small mockup that could eventually help constructing full scale homes, saving money and time. The current system consists of solar panels that are connected to the household, and to an electrolyser. When the sun is shining, the solar panels produce electricity that is used to produce hydrogen and to provide energy to a residential home. The energy demanded by the household during the period of sunlight will be just a portion of the total energy needed to run

asymmetry, could be the cause of the "abnormal" appearance of SC 23. The new magnetic dipole begins to lose part of its energy even during the descending phase of SC 22, so that the activity of SC 23 proves to be below the predicted values. Key words: Sun − solar flares – solar activity cycles − N-S asymmetry. INTRODUCTION Solar flares are wonderfully complex phenomena, seen as sudden and intense increases in brightness on the solar disk. They occur when magnetic field loops undergo reorganization

It was Friday the 15th. I got up early and there was a sun shining outside my window. I cut school. I thought the best thing to do is to go to the river with my friends. When I was going outside I saw a black cat crossing my path. I've already known that this day isn't going to be one of the bests in my life. Later it turned out that my worst fears were realized. I bought a bus ticket. When I got to the bus stop and I understood that I'm late, it really put me out of humour. Me and my friend decided

Memo from CEO to Manager: Today at 11 o’clock there will be a total eclipse of the sun. This is when the sun disappears behind the moon for two minutes. As this is something that cannot be seen every day, time will be allowed for employees to view the eclipse in the parking lot. Staff should meet in the lot at ten to eleven, when I will deliver a short speech introducing the eclipse, and giving some background information. Safety goggles will be made available at a small cost. Memo from Manager

you see in this simple sun-planet system. Specifically, what happens to the central object (the Sun)? Answer: The sun moves too. Can you explain why the central object moves? Answer: The Sun is pulled by the gravitational forces between itself and the planet. HINT: Is gravitational attraction only the sun pulling on the planet? Does the planet orbit in a perfect circle? Is the sun at the center? Answer: The planet orbits in an elliptical. No, the Sun is in focus off to the

accented to cook the dinner. We took our meal and it was delicious. We took rest for a while and started off on our journey again. The boatman tried to reach the destination before the sunset as it was late afternoon. The sun was setting with all its glory. The setting sun reflected on the gleaming water and created an ethereal feeling among us. The boat moved slowly and we reached our destination. It was dark all round. This journey remained entrenched in my memory. It gave me much pleasure

Solar Activity Most people just look up at the sun and enjoy the warmth and brightness of the light. Without the sun there would be no life on earth. If a person took the time to analyze it, he or she would find more than bright light and warm weather. The sun is very active with solar cycles, sunspots, and most of all solar flares. It is amazing how much the suns activity can affect us on Earth. A solar cycle is when the sun's magnetic field rotates a full 360 degrees, causing its poles to switch

the Sun; the most important and charming creation of almighty. At the same time, we have the technology which can convert sunlight to electricity and store them for long time. That is why I believe that solar energy is better than any other energy sources because of unlimited energy, lower cost and no interruption in supplying energy. Firstly; it contains unlimited energy for lifetime. According to Dionne (2011) who is a professor of Material Science Department of Stanford University; the sun provides
