No Two Snowflakes Alike - True or False

Youve likely been told no two snowflakes are alike -- that each is as individual as a human fingerprint. Yet, if youve had the chance to closely examine snowflakes, some snow crystals do look like others. Whats the truth? It depends how closely you look. To understand why theres dispute about snowflake similarity, start by understanding how snowflakes work. How Snowflakes Form Snowflakes are crystals of water, which has the chemical formula H2O. There are multiple ways water molecules can bond and stack with each other, depending on the temperature, air pressure, and concentration of water in the atmosphere (humidity). Generally the chemical bonds in the water molecule dictate the traditional 6-sided snowflake shape. One a crystal starts forming, it uses the initial structure as the basis to form branches. The branches may continue to grow or they can melt and reform depending on conditions. Why Two Snowflakes Can Look the Same Since a group of snowflakes falling at the same time form under similar conditions, theres a decent chance if you look at enough snowflakes, two or more will look the same to the naked eye or under a light microscope. If you compare snow crystals at the early stages or formation, before they have had a chance to branch out much, the odds that two of them might look alike is high. Snow scientist  Jon Nelson at Ritsumeikan University in Kyoto, Japan, says snowflakes kept between  8.6 ºF and 12.2 ºF (-13 ºC and -11 ºC) maintain these simple structures for a long time and can fall to Earth, where it would be hard to tell them apart just looking at them. Although many snowflakes are six-sided branched structures (dendrites) or hexagonal plates, other snow crystals form needles, which basically look much like each other. Needles form between 21 °F and 25 °F and sometimes reach the ground intact. If you consider snow needles and columns to be snow flakes, you have examples of crystals that look alike. Why No Two Snowflakes Are Alike While snowflakes might appear the same, at a molecular level, its very nearly impossible for two to be the same. There are multiple reasons for this: Water is made from a mixture of hydrogen and oxygen isotopes. These isotopes have slightly different properties from each other, altering the crystal structure formed using them. While the three natural isotopes of oxygen dont significantly affect crystal structure, the three isotopes of hydrogen are distinctly different. About 1 in 3,000 water molecules contains the hydrogen isotope deuterium. Even if one snowflake contains the same number of deuterium atoms as another snowflake, they wont occur in the exact same places in the crystals.Snowflakes are made up of so many molecules, its unlikely any two snowflakes are exactly the same size. Snow scientist  Charles Knight with the National Center for Atmospheric Research in Boulder, Colorado estimates each snow crystal contains around 10,000,000,000,000,000,000 water molecules. The number of ways these molecules can arrange themselves is nearly infinite. Each snowflake is exposed to slightly different conditions, so even if you starte d with two identical crystals, they wouldnt be the same as each by the time they reached the surface. Its like comparing identical twins. They might share the same DNA, but they are different from each other, especially as time passes and they have unique experiences.Each snowflake forms around a tiny particle, like a dust mote or pollen particle. Since the shape and size of the starting material isnt the same, snowflakes dont even start out alike. To summarize, its fair to say sometimes two snowflakes look alike, especially if they are simple shapes, but if you examine any two snowflakes closely enough, each will be unique.

The Universal Soul in The Parable of the Chariot, Katha...

The Universal Soul in The Parable of the Chariot, Katha Upanishad 3.3-3.12 The word â€Å"Atman† is translated into English as â€Å"soul† or â€Å"self.† Yet Atman in Hinduism has a much richer meaning than our standard western concept of soul. For example, Atman is understood as divine and equivalent to Brahman, the ultimate reality. Each person’s Atman is the same, and each is identical with Brahman. Therefore Atman could also be translated, â€Å"Universal Soul,† â€Å"Eternal Soul,† or â€Å"All-Soul.† The Katha Upanishad speaks at length about the nature of Atman, how one might attain to it and thereby attain to Brahman. Attainment to Atman is dependent on the control of those aspects of the person that are transitory and not eternal like Atman; these†¦show more content†¦In the same manner a chariot with no rider has neither purpose nor anyone to guide it. Therefore the soul and the body need each other, but the body is subordinate to the soul just as the chariot is subordinate to the rider. Yet surprisingly it is not the rider, not the soul, who actually drives the chariot and holds the reins, but yet another aspect of the person: â€Å"Know thou the intellect (buddhi) as the chariot-driver† (Katha Upanishad, 3.3). With the addition of intellect in this passage the simple relationship between the soul and body becomes more complex. For here we see that it is not soul who directly steers the course of the body, but the intellect. It seems that we are to understand the soul as some sort of royal passenger on this chariot who need not lift a finger in its operation. In the same sense the soul is completely detached from the body and all the apparatus required for the body to live. It is thus easy to see why the soul is so difficult to attain: it is not concerned with bodily life and the things that characterize bodily life. Still, there must be some connection between the soul and the intellect that the parable does not explain. For it seems to me that a chariot would continue to operate without its royal passenger, and that the chariot-driver would be the only one of the two necessary for its function. Yet the body surely cannot function without the soul. Therefore we

Mixed Martial Arts Essay Thesis Example For Students

Mixed Martial Arts Essay Thesis The more dangerous vale-Loud-style bouts Of the early Buffs were made safer with the implementation of additional rules. Aimed at increasing safety for competitors, which leads to the popular regulated form of MA seen today. During the Classic Greek era there existed an ancient Olympic combat sport, known as Penetration which featured a combination of grappling and striking skills, similar to modern mixed martial arts. This sport originated in Ancient Greece and was later passed on to the Romans. In the late 1 *ass to early asses, the concept of combining the elements of multiple martial arts was popularized in the west by Bruce Lee via his philosophy of Jet June Do. Mixed martial arts competitions were introduced in the United States with the first ultimate Fighting Championship (CIFS) in 1993. The sport reached a new peak of popularity in North America in the December 2006 rematch between the JIFF light heavyweight champion Chuck Lidded and former champion Toto Rotor. The high profile of modern MA promotions such as ICP and Pride FCC has fostered an accelerated development of the sport. As competitions became more and more common, those with a base in striking arts became more competitive as they cross trained in arts based around takeaways and benison holds, likewise, those from the varying grappling styles added striking techniques to their arsenal. This increase of cross-training resulted in fighters becoming increasingly multidimensional and well-rounded in their skill- sets. Since the late asses, both strikers and grapples have been successful at MA though it is rare to see any fighter Who is not schooled in both striking and grappling arts reach the highest levels of competition. The rules for modern mixed martial arts competitions have changed significantly since the early days of vale outdistances shoot wrestling, and AFC 1, and even more from the strict style of penetration. As the knowledge of fighting techniques spread among fighters and spectators, it became clear that the original minimalist rule systems needed to be amended. The main motivations for these rule changes were protection of the health of the fighters. The new rules included the introduction of weight classes; as knowledge about submissions spread. There are nine different weight classes in the Unified Rules of Mixed Martial Arts, These nine weight classes include flyweight (up to 125 lb / 56. 7 keg), bantamweight (up to 1 AS lb / 61. keg), featherweight (up to 145 lb 65,8 keg), lightweight (up to SIS lb / 70. 3 keg), welterweight (up to 170 lb / 77. 1 keg), middleweight (up to 185 lb / 83 9 KGB), light heavyweight (up to ASS lb / 93 0 KGB), heavyweight (up to 265 lb / 120. keg). Small, open-fingered gloves ever introduced to protect fists, reduce the occurrence of cuts and encourage fighters to use their hands for striking to allow more exciting matches. Time limits were established to avoid long fights with little action Where competitors conserved their strength. Matches without time limits also complicated the airing of live events. The t ime limit in cost professional fights are three S minute rounds, and championship rights are normally five 5 minute rounds. Victory in a match is obtained in a number Of ways. One Of it is a stoppage by the referee, Which is called a technical knockout(TOOK), where the referee stops the fight if a fighter becomes dominant to the point where the opponent cannot defend himself and is taking excessive damage or if a fighter appears to be losing consciousness as he or she is being struck or if a competitor has a significant injury such as a broken bone. A knockout, which is as soon as a fighter is unable to continue due to legal strikes causing his opponent to be unconscious, his opponent is declared the winner. .u0519b2539f7e0cab615b88ffb764e7aa , .u0519b2539f7e0cab615b88ffb764e7aa .postImageUrl , .u0519b2539f7e0cab615b88ffb764e7aa .centered-text-area { min-height: 80px; position: relative; } .u0519b2539f7e0cab615b88ffb764e7aa , .u0519b2539f7e0cab615b88ffb764e7aa:hover , .u0519b2539f7e0cab615b88ffb764e7aa:visited , .u0519b2539f7e0cab615b88ffb764e7aa:active { border:0!important; } .u0519b2539f7e0cab615b88ffb764e7aa .clearfix:after { content: ""; display: table; clear: both; } .u0519b2539f7e0cab615b88ffb764e7aa { display: block; transition: background-color 250ms; webkit-transition: background-color 250ms; width: 100%; opacity: 1; transition: opacity 250ms; webkit-transition: opacity 250ms; background-color: #95A5A6; } .u0519b2539f7e0cab615b88ffb764e7aa:active , .u0519b2539f7e0cab615b88ffb764e7aa:hover { opacity: 1; transition: opacity 250ms; webkit-transition: opacity 250ms; background-color: #2C3E50; } .u0519b2539f7e0cab615b88ffb764e7aa .centered-text-area { width: 100%; position: relative ; } .u0519b2539f7e0cab615b88ffb764e7aa .ctaText { border-bottom: 0 solid #fff; color: #2980B9; font-size: 16px; font-weight: bold; margin: 0; padding: 0; text-decoration: underline; } .u0519b2539f7e0cab615b88ffb764e7aa .postTitle { color: #FFFFFF; font-size: 16px; font-weight: 600; margin: 0; padding: 0; width: 100%; } .u0519b2539f7e0cab615b88ffb764e7aa .ctaButton { background-color: #7F8C8D!important; color: #2980B9; border: none; border-radius: 3px; box-shadow: none; font-size: 14px; font-weight: bold; line-height: 26px; moz-border-radius: 3px; text-align: center; text-decoration: none; text-shadow: none; width: 80px; min-height: 80px; background: url(https://artscolumbia.org/wp-content/plugins/intelly-related-posts/assets/images/simple-arrow.png)no-repeat; position: absolute; right: 0; top: 0; } .u0519b2539f7e0cab615b88ffb764e7aa:hover .ctaButton { background-color: #34495E!important; } .u0519b2539f7e0cab615b88ffb764e7aa .centered-text { display: table; height: 80px; padding-left : 18px; top: 0; } .u0519b2539f7e0cab615b88ffb764e7aa .u0519b2539f7e0cab615b88ffb764e7aa-content { display: table-cell; margin: 0; padding: 0; padding-right: 108px; position: relative; vertical-align: middle; width: 100%; } .u0519b2539f7e0cab615b88ffb764e7aa:after { content: ""; display: block; clear: both; } READ: Uwi course EssayNext, a submission is when the referee stops the match when the fighter is caught in a submission hold and is in danger of being injured; often times a fighter gets choked unconscious; other times it is when a bone has been broken in a submission hold.

The Yellow Wallpaper - Journey Into Insanity Essays (998 words)

The Yellow Wallpaper - Journey into Insanity In "The Yellow Wallpaper", by Charlotte Perkins Gilman, the dominant/submissive relationship between an oppressive husband and his submissive wife pushes her from depression into insanity. Flawed human nature seems to play a great role in her breakdown. Her husband, a noted physician, is unwilling to admit that there might really be something wrong with his wife. This same attitude is seen in her brother, who is also a physician. While this attitude, and the actions taken because of it, certainly contributed to her breakdown; it seems to me that there is a rebellious spirit in her. Perhaps unconsciously she seems determined to prove them wrong. As the story begins, the woman -- whose name we never learn -- tells of her depression and how it is dismissed by her husband and brother. "You see, he does not believe I am sick! And what can one do? If a physician of high standing, and one's own husband, assures friends and relatives that there is really nothing the matter with one but temporary nervous depression -- a slight hysterical tendency -- what is one to do?" (Gilman 193). These two men -- both doctors -- seem completely unable to admit that there might be more to her condition than than just stress and a slight nervous condition. Even when a summer in the country and weeks of bed-rest don't help, her husband refuses to accept that she may have a real problem. Throughout the story there are examples of the dominant - submissive relationship. She is virtually imprisoned in her bedroom, supposedly to allow her to rest and recover her health. She is forbidden to work, "So I . . . am absolutely forbidden to "work" until I am well again." (Gilman 193). She is not even supposed to write: "There comes John, and I must put this away -- he hates to have me write a word." (Gilman 194). She has no say in the location or decor of the room she is virtually imprisoned in: "I don't like our room a bit. I wanted . . . But John would not hear of it." (Gilman 193) . She can't have visitors: "It is so discouraging not to have any advice and companionship about my work. . . but he says he would as soon put fireworks in my pillow-case as to let me have those stimulating people about now." (Gilman 196). Probably in large part because of her oppression, she continues to decline. "I don't feel as if it was worthwhile to turn my hand over for anything. . ." (Gilman 197). It seems that her husband is oblivious to her declining conditon, since he never admits she has a real problem until the end of the story -- at which time he fainted. John could have obtained council from someone less personally involved in her case, but the only help he seeks was for the house and baby. He obtains a nanny to watch over the children while he was away at work each day: "It is fortunate Mary is so good with the baby." (Gilman 195). And he had his sister Jennie take care of the house. "She is a perfect and enthusiastic housekeeper." (Gilman 196). He does talk of taking her to an expert: "John says if I don't pick up faster he shall send me to Weir Mitchell in the fall." But she took that as a threat since he was even more domineering than her husband and brother. Not only does he fail to get her help, but by keeping her virtually a prisoner in a room with nauseating wallpaper and very little to occupy her mind, let alone offer any kind of mental stimulation, he almost forces her to dwell on her problem. Prison is supposed to be depressing, and she is pretty close to being a prisoner. Perhaps if she had been allowed to come and go and do as she pleased her depression might have lifted: "I think sometimes that if I were only well enough to write a little it would relieve the press of ideas and rest me." (Gilman 195). It seems that just being able to tell someone how she really
