Julius CaesarFate vs. Free Will Essay Example

Julius CaesarFate vs. Free Will Essay Julius Caesar Fate vs. Free Will In Julius Caesar, two forces compete for dominancefate and free will. Fate was portrayed as prophecies and omens. Free will was the character’s ability to overcome itwhich they tried and didn’t. Caesar, Cassius, and Brutus have troubles overcoming their fate in the play. In the end of the play, all three of them fall to their fatethis is Shakespeare’s way of showing the fine line between the two. Caesar’s fate was the most obvious to him and the readers. In the beginning we see how Caesar uses his power over his own fate by ignoring the soothsayer in the crowd that warns him of the ides of March. On the ides of March, Caesar confronts the soothsayer and tells him that it is now the day he was warned of but he doesn’t what the rest of the day holds for him. Earlier that day, Calphurnia tells Caesar about her dream and how everyone went to his statue to bathe their hands in the blood coming out of the statue in her dream (Act 2, sc. ii, 13-26). Decius Brutus goes to Caesar’s home and when he finds out that Caesar would not be going, he retells Calphurnia’s dream as a blessing upon him. On Caesar’s way to the Senate, Artemidorus attempts to warn him and show him the exact plan of his murder, but Caesar refuses since he is filled with pride at the moment. Through all the times that Caesar’s free will could have helped him save his own lifehe chose to ignore it, leading to his death. Cassius was very aware of his own fate up to the very end. He took the largest precautions to overcome it.

Cassius thought that he could always do something to make his current position in life better. Cassius desire was to make sure that Caesar would not become emperor, but Caesar’s fate was to become the emperor. Because he was so driven by this desire, he went out of his way to kill Caesar. Later on, Cassius changes his mind and sees that the gods are not looking upon their mission too favorably. He died by his own sword, seeing that the eagles presented his fate which was too much to overcome. Brutus always believed that bad things would not happen to good people. Brutus went along with the flow of things and accepted whatever happened. This requires Cassius to go to extreme measures to convince Brutus to join the conspirators. Brutus’ form of death was pure apathy. He dreamed of Caesar’s ghost and being reunited with him at the battle of Philippi. In the end of the battle, he falls upon his own sword and fulfills his dream. Shakespeare gives off the message that failing to acknowledge your fate will lead to permanent consequences such as death. Cassius accepted his fate in the end. Brutus was never strong with using his free will, but he died like Cassius. Caesar’s control over his free will was just as weak as Brutus, but Caesar took a nobler approach at defying it. All three of their deaths show an example of how you should use your free will very carefully and if you let your guard down†¦you fate will get the better of you and being careless will cost you greatly.

Power Generation from Radio Wave Technology

Power Generation from Radio Wave Technology Introduction Radio wave technology is the use of airwaves in transmitting and receiving information. It is the foundation of most of our communication in the present day. Radio waves fall under the group of waves termed electromagnetic radiation, which travel at the speed of light (3108 m/s).Advertising We will write a custom research paper sample on Power Generation from Radio Wave Technology specifically for you for only $16.05 $11/page Learn More These types of waves (including light, infrared, microwaves and x-rays) are classified based on their wavelengths and frequencies. The frequencies of radio waves lie between 300GHz to 3 kHz with wavelengths of 1mm to 100km. Some of the communication equipments that use radio waves include satellite dishes, radar, radios, television, mobile phones and wireless internet. The use of radio waves for powering electronic devices had not been exploited due to the nature of waves to weaken and dissipate as they spread du e to their interaction with other waves and matter. Recently, a growing interest in alternative sources of energy that could provide efficient power in remote and sensitive locations has led to research into radio wave power generation. This paper looks at the history of radio waves and how power can be generated from them and how it can be applied in electronic devices. History and growth of radio wave technology The history of radio waves as medium for transmitting information started way back in the 1860s when James Clerk Maxwell, a physicist from Scotland, envisaged the existence of the waves. His prediction was enhanced in 1886 by Heinrich Rudolph Hertz, a German physicist, who went a notch further to show how variation of electric current could be sent into space as radio waves (Bellis 3). He was able to generate and compute the first waves by using an oscillator for transmitting the waves and a metal loop for detecting them (Parker 3). In 1895 Guglielmo Marconi, from Italy, s ent a radio signal over a distance of 100m and received it. He used crafted antenna, transmitter, and condenser and had connections on the ground that could receive the signals. He also sent a wireless signal across the English Channel in 1899(Bellis 5), a distance of 3.5 miles. In addition, Nikola Tesla helped in developing and enhancing wireless radio transmitters.Advertising Looking for research paper on natural sciences? Let's see if we can help you!

In 1899, the U.S Army adopted the wireless system and in 1901, the Navy also adopted the system. Lee Deforest invented the space telegraph in the early 1900s where amplifiers were used to strengthen weak signals (Bellis 12). Marconi was able to transmit voice in 1914 over a distance of 50 miles (Bellis 12). Over time, many people aided in developing and enhancing radio wave communicati on and today we have 4G technologies that send information at very high speeds, besides audio and video streaming. Power generation using radio waves Electromagnetic radiation and photons Electromagnetic waves can be said to have an atomic structure and can either generate or expend energy (â€Å"Electromagnetic waves† par. 7). The electromagnetic radiation, in quantum terms, is said to have photons transporting energy (Joules). A single photon has energy equal to hf. h is Planck’s constant =6.62610-34 J s and f =frequency of photon v is the velocity of light= 3108 m/s and ÃŽ » =wavelength of photonAdvertising We will write a custom research paper sample on Power Generation from Radio Wave Technology specifically for you for only $16.05 $11/page Learn More Collection of radio waves energy Radio wave energy can be collected and harnessed using various equipments and components. The generation circuit has components such as antenna, capacitors , diodes, transistors, inductors and resistors. The antenna is used for receiving the electromagnetic signal. This signal received is then rectified. The rectifying circuit is made of diodes. Once the signal has been rectified, it is boosted before being stored in capacitors. The power stored is used to drive a load or resistor via a switching circuit. Figure 1: Block diagram for ground circuit for capturing radio waves Figure 2: Circuit diagram for capturing and generating power from radio waves MOS transistors are used for switching or controlling the stored power to the load. The source of the MOSFET (for switching) is connected to the storage capacitor with the drain connected to the load. The link between the capacitor and load is created when the voltage of the stored charge is equivalent to the sum of the threshold voltages of both MOSFETs (Ishida et al. 4). Potential of radio wave harvesting Radio wave energy can be efficiently and sufficiently harvested if various facto rs are considered. These are:Advertising Looking for research paper on natural sciences? Let's see if we can help you!

The power generated can be used in devices such as: LED monitor lights Sensors LCD display thermometer Implants in the biomedical field Charging the battery for cell phones Safety hard hat Possibility of radio waves technology replacing batteries Nowadays, there is a high requirement for efficient energy sources. Furthermore, the sources should be mobile and flexible. Batteries are usually bulky, require regular maintenance and have a limited life and as such require constant replacement. With the rapid advancement in technology where electronic gadgets and devices are continually made smaller and efficient, their energy requirements have decreased over time. Proper harnessing of radio wave energy could provide an alternative source of energy for powering small electrical devices such as sensors. This is through capturing the electricity produced by the radio waves and is depended on how far the transmitter is and the magnitude of the power generated by the transmitter. The power that can be harnessed from these waves is in the range of microwatts to milliwatts which can be sufficient for powering the devices especially in remote locations. Thus, there is a possibility of radio waves technology replacing batteries. Conclusion and personal thought about radio wave technology application in future Energy harnessed from wasted radio waves is small. This energ y may not be adequate to power large electronic devices but technology has been changing very rapidly in the recent years. Many companies are developing gadgets that are very small, thus requiring less power. For example, the mobile phone industry has seen a reduction in the size of the phones but with more installed phone features and applications. Nokia has come up with a harvesting device embedded in a cell phone. This device is able to charge the phone’s battery (Dixon 3). This means that in the future, many miniature gadgets will have been developed which will totally rely on radio frequency energy. Furthermore, radio wave energy will provide a reliable source of energy since the use of cell phones, television, radios and other communication devices is on the rise. Bellis, Mary.
