The proton, as published in Nature, has shrunk by approximately 0.00000000000003 millimeters. In response to this discovery, the average person might most likely say, “Oh my goodness, I do not really care,” because to him age this minute difference in the size of the proton might seem trivial. However, upon closer consideration, this small change in size will clearly appear to be important and noteworthy. As mentioned by renowned researcher Randolf Pohl, protons remain a mystery to nuclear physicists, especially because of their complex internal structure. Consisting of miniature particles known as quarks, protons spread their positive charge throughout a spherical area. The interaction between the positively charged proton and the negatively charged electron allows physicists to measure the size of the proton. Thus, since the 1960s, numerous physicists have been able to measure the radius of the proton with tremendous accuracy and estimate the radius at approximately 0.8768 femtometers. However, recent results acquired by Pohl and his team indicate that the proton is about 4 percent smaller than the size that was previously estimated. In his experiment, Pohl used the muon, a particle also known as the cousin of the electron. After shooting muons from a particle accelerator into hydrogen atoms, Pohl and his team, equipped with lasers, accurately measured relevant muonic energy levels and found the smaller size of the proton. The 4 percent decrease in the size of the proton is a very serious discrepancy, as stated by renowned physicist Ingo Sick, and is definitely a mindboggling matter. In the atomic realm of quantum mechanics, in which measurements regularly exceed ten decimal places, the slightest difference in the size of the proton can very well challenge existing theories as well as four decades of previous measurements. As a result of the 4 percent difference, Sick claims, “there is really something seriously wrong someplace.” In my opinion, I truly think that Sick is correct because it is highly unlikely that such a difference in the size of the proton could have been overlooked for such a long time. Possibly, Pohl and his team made some mistakes in the experimental process or in the calculations. However, if proven to be true, Pohl’s remarkable discovery of the smaller size of the proton would significantly impact the science of today. One basic complication would include the increase in the attractive forces between the proton and the electron due to the smaller radius of the proton. Similarly, other complications would occur and numerous modifications would have to be made in the current scientific theories such as the standard hydrogen model.
Article 2: "Sinister Motion" may influence soccer referees
Researchers allege that World Cup referees make biased calls based on the direction in which players are moving. According to the article, there is a 5 percent higher probability for referees to call a foul if the player is moving from right to left rather than from left to right. However, while motion may seem ominous moving from one direction to the other, as stated in the article, I wholeheartedly feel that the direction of the players’ movements do not influence the referees’ decision regarding fouls. Statistically speaking, a 5 percent difference is truly not a large margin that can definitely support the researchers’ claim. Even though referees, because of their diagonal system of covering the field, may frequently see players who commit fouls moving right to left than left to right, they tend to make their decisions not necessary on the motion of the attack, but rather on the nature of the attack. Whenever the match is stopped by a referee because of dangerous play, contact between two or more players is clearly noticeable regardless of the direction from which it came. Based on the severity of the contact, the referee will issue a free kick, a penalty kick, and/or a card. However, many times, World Cup referees, like all soccer referees worldwide, simply make some poor calls. In my opinion, these poor choices, which may truly be mistakes, justify the mystery behind the unfair decisions made by referees and explain the presumption that referees tend to favor the offensive team. As a result, numerous people, including me, say that a soccer match is often like a game of Texas Hold’em. You do not know that you have won until the ending whistle is blown and the fifth card is flipped. However, in the World Cup Final, Netherlands blindly went all in with a pair of fives, while Spain calmly matched the Dutch wager, as it held a royal flush in its hands from the very beginning.
Article 3: Why you should never arm wrestle a saber-tooth tiger

Honestly, I do not understand why anyone would even bother approaching the saber-toothed tiger, let alone think about arm wrestling this prehistoric cat. With their weights ranging from 160 pounds to 220 pounds, saber-toothed tigers were definitely powerfully built creatures and had imposing appearances, as clearly evidence in the picture hyperlinked above. In addition to their strong physique, they had long, sharp canines up to 7 inches in length and had the ability to open their jaw extremely wide and run extremely fast. These statistics, along with the intimidating picture, clearly indicate that an arm wrestling match between a human and a saber-tooth tiger will not only end in a defeat for mankind but also result in several fatal injuries for the human contender. This fascinating article further explains that the unfairness of the arm wrestling match is due to the fact that the muscles of the saber-tooth tigers’ forelimbs are naturally powerful and much stronger than the muscles of the upper extremities of human beings. For instance, when tested with 28 other cat species, as mentioned in the article, “the saber-toothed cat fell well outside the normal range -- while their leg bones scaled to size, their arm bones were exceptionally thick for their length.” The thought of saber-tooth tigers having abnormally muscular forelimbs never occurred to me because I was mostly focused on their large fangs. I always believed that saber-tooth tigers primarily used their teeth to hunt prey, but after reading this article, I now know that this is not the case. Paleontologist Julie Meachen-Samuels claims that the canines made the saber-tooth tigers more vulnerable to fracture than cats living today. As a result, the primitive cats mostly likely used their muscular arms to immobilize prey and protect their teeth from fracture.
