Olbers’ Paradox: Infinite Stars‚ Dark Sky‚ But Why? Olbers’ Paradox Olbers’ Paradox has been around since the 1500’s but is named after Heinrich Olbers from 1826. The paradox is that the whole night sky should shine as brightly as a star but the sky is mostly dark. The foundation for this paradox rests on the assumption that the universe is unchanging with infinite proportions‚ meaning it is infinitely old with an infinite number of stars‚ whose light shines infinitely. We now know these things to

Introduction: It is often taught that if we drop two objects of varying masses simultaneously under the same conditions‚ they will reach the ground at the same time. However‚ this is rarely seen in the natural world. This discrepancy is attributed to a frictional force called drag. In a previous experiment‚ multiple variables thought to affect drag were tested. Previously tested variables were weight and surface area. It was found that weight had an inverse exponential effect on time it took the

Humans use technology reach many parts of the universe around us‚ helping to scope out the unknown‚ but although progress has been made mankind only knows a fragment of the universe. As Dean Koontz once stated‚ “in an infinite universe‚ anything that could be imagined might somewhere exist” helping to open our minds to the fact that we are possible not the only life through out the universe (Koontz). Many theories and arguments have been made on how the universe came about. It might seem that these

The first biophysical principle I am going to talk about is force summation. Force summation is the combination of different body parts moving in order to create a greater force. For an object to move‚ momentum has to be applied to that object. So‚ the amount of momentum an object has‚ is determined by the sum of all forces generated by each moving body part. In order to gain maximum momentum‚ the force needs to be generated by using 4 principles. The first‚ use as many segments of the body as possible

flight‚ and any moment in time the arrow takes up a certain place in space. Before the flight‚ it was in a different place and later on it was in a different place in space but in the present moment when the arrow was in flight‚ it was there. But‚ if it was at the place in space when it was in flight and not somewhere else then that means it wasn’t moving. Therefore no motion was taking place. He states the same conclusion as the previous argument which was the same as the first argument‚ the Dichotomy

POWER CALCULATION Power is the quantity work has to do with a force causing a displacement. It is the rate at which work is done. (http://www.physicsclassroom.com/class/energy/u5l1e.cfm) We can calculate power with using the following equation. In this experiment I calculated my power with Power (watt)=mass (kg) *gravitational acceleration (m/s2)*height(m)/time (s) I made the experiment with my controller for getting more reliable datas.I calculated my power with cliambing upstairs and

Samantha Weir NSET 111 Take Home Essay February 16‚ 2014 Our Universe was created billions of years ago. We have no way of knowing exactly how this happened‚ nor how or if it will end. The creation of the universe is greatly debated religiously and scientifically. The future of our universe is a popular topic‚ but still remains a mystery. There are many theories as to what will happen to the universe and factors to be accounted for. The fact that we do not have the ability to travel into the

Scientific question: How does the incline of a slope influence the acceleration of a cart when it travels down a wooden plank? Introduction: What is an incline plane? Commonly referred to as a ramp or a slope‚ an incline plane is an even surface that is titled at an angle. An object placed on the tilted surface will often slide down the surface‚ accelerating because of an unbalanced force. The rate at which an object travels down the slope is dependent upon how tilted the slope is; the greater

Humans have always had a fascination with flying since the beginning of time. Hot air balloons were invented in 1783‚ one step closer to the airplane. The balloon is filled with hot air‚ which makes the balloon fly to the air because hot air is lighter than cool air. The only problem with the hot air balloon was that you could not control the direction it was going. The first airplane was actually a glider. This aircraft was launched from a cliff or from any high place. It rode on the wind

"Butterfly Effect" was perhaps one of the best films I have ever seen. I found it mysterious‚ interesting and fascinating. I wanted to write my reaction paper about "Butterfly Effect" because of the similarity to the film we saw in class called "Donnie Darko". Both films investigate the issue of destiny thoroughly. Both film had a male character that has memories‚ dreams or black outs which make them at first confused. But later on‚ they realized the power they have in order to change their destiny
