In our lifetime, the ocean has remained untamed and unexplored. “Modern Day” technology has only been able to come so far in venturing out to sea and to the world below the surface. However, in the past 10 years this has all been changed. With research being done throughout the world studying the movement and anatomy of fish, the gap between the surface and the sea floor could be speedily lessening. For years humans have marveled at the speed and grace of most marine life. The lack of drag, the force propulsion, and the ability to live at such impossible depths have been forever the envy of submarines and sea explorers. After years of observing these incredible functions, researchers are finally beginning to mimic and apply these characteristics to marine technology. These robo-fish hold the potential to make underwater exploration far more accessible, safer, and more efficient due to their naturalistic design.
The first two notable robotic fish were the original robotuna and a fish made by Mitsubishi. While neither of these had ocean exploration in mind while they were being innovated, they did lay the bricks down for the road that would lead to today’s strides forward. The first of the two mentioned fish was created purely to study how fish swim. Through this marvel, we were able to better understand just how fish are able to propel themselves forward in even the harshest of ocean storms or currents. Researchers tried a genetic algorithm to program the fish in a way where it could analyze the vortices to better stabilize. Early incarnations worked poorly but as the system evolved the RoboTuna's abilities improved. Visualization techniques showed that the system had evolved so that the RoboTuna was taking advantage of vortices t...

Acanthostega had a fish-like tail and gills for breathing under water, this being the aquatic part of it. But at the ends of the arms were “peddle-shaped” appendages, thought to be the first “hands” on Earth. Clack’s discovery proved that some fish had arms and legs in the water. It showed that arms and legs were already evolved before organisms started actually living on land, they were used more for survival than walking. In a sense, the “blueprints” of an arm were already in place.

Review: The opportunity and endeavor of exploring the Earth’s oceans can reap great rewards for mankind and unravel many of the mysteries that the Earth has left to discover.
When people hear the term “FIRST Robotics” or hear anything related to robotics, they automatically assume that it has something to do with robots destroying each other or nerds sitting in the corner eating pizza and building small robots; I used to be one of those people who thought that before joining FIRST Robotics. In all honesty, I was very reluctant on becoming a part of FIRST Robotics in the first place because I did not know if I would fit in or even enjoy it for that matter. However, thanks to two special people I gave FIRST Robotics a shot, and I’m thankful that I did because I wouldn’t be the person that I am today. FIRST Robotics has greatly impacted my high school experience by teaching me life skills that I can’t learn in the classroom, forming new bonds and
Resarch Paper Proposal: The Box Jellyfish As far back as I can trace my memories I remember that as a child I always liked to be in the water. Swimming pools were my absolute favorite. Wherever I went, I would always ask if there was a swimming pool. However, things changed when my parents took me to Florida for the first time.
Modern advancements have aided our generation and will help many to come. They brighten our rooms, power our cars, and cure our diseases. They seem to be revolutionary and make us wonder how we ever managed to live without them, but are modern advancements actually that good? There is an expression, to take the bad with the good, but what if the bad out weighs the good? Sonar is imperative to navigation, location, and observation, but it also is a danger to marine life, more specifically whales. It can confuse, injure or even kill whales, its unsafe to be using these types of devices. This is an issue because whales play a vital role in the food web and affect an estimated 5,000-12,000 different species (NBC News). Though whale injuries are quite horrific we do need sonar for research and new modern developments. This proves to be an issue over the controversy of whether or not sonars are acceptable to be used.
Prove It (text evidence…) - describe the adaptation: As stated by nmfs.noaa.gov,” Blob fish has gelatinous skin and its density is slightly lighter than water’s density, making them able to float around in the deep sea instead of spending their energy for swimming.”
This force now can be used by the diver not only to go up, but to rotate and therefore perform various dives.

The deep sea is one of the most hostile environments in the world, which a living organism is subjected to. As you progress from the surface (the epipelagic zone) through to the abyssopelagic zone near the basin of the ocean; the environmental characteristics begin to alter dramatically. Light, pressure, oxygen, temperature and food are abiotic factors that have all led to the fascinating adaptations of deep sea life. Pressure alone increases by 1 atmosphere for each 10m in depth which is an astonishing rate. The deep sea temperature remains between 2-4°c, which is just another factor inhabitants must overcome in order to survive, along with a reduced quantity and accessibility of essential factor’s like ;oxygen, food and light[3].
The film Big Fish delves into the ideas of mythology in such a way as to be relatable to a modern audience. At the center of the film is the struggle between logos and mythos, William Bloom vs. Edward Bloom. People are increasingly trying to apply logic and reason to their everyday lives to explain why things happen, but there are certain aspects of life that are currently beyond the reach of logos, such as death and the questions of existence. This is where mythos steps in and is able to provide “reasons” for why things happen as they do and why humans exist in the first place. Big Fish is told in a manner that resonates with the viewer, because most of the tales are told by Edward Bloom, one of the protagonists in the movie. He weaves magical tales of intrigue, mystery, and impossibility when telling them to his family, and for this reason his son, William Bloom, doesn't believe any of them ever happened. As a reporter, William needs facts and evidence to back up his father's miraculous claims. The viewer would be of the same mind if they attempted to apply logos to Edward's stories instead of looking at them through the intended mythos paradigm. Ingrained in each story are inklings of the truth and William must learn the hard way that his father hasn't been lying to him his whole life, but merely embellishing some of the finer points in each story. Ordinary stories aren't as hard to believe, but they aren't as easily remembered either. A person's true actions and life may be forgotten in time, but they can live on through their stories, as Edward does. This is how mythology exists today: as a collection of stories passed down from generation to generation and recorded in the histories. There are many parities between the movi...

Sailing has been around for millennia, and is considered to be one of the earliest and most environmentally friendly methods of water transport. Sailboats act as a method of transportation, exercise, and entertainment. These now more structurally developed and masterfully modeled ships have been engineered for efficiency, and these advancements have ensured durability and speed among modern sailboats. The great strength and ability of sailboats has given competitive owners the opportunity to participate in races, but generally sailboats have come to exist as more of a relaxed hobby. The expensive activity of sailing is demanding both physically and mentally, as it tests anticipative abilities and endurance. To understand the physics concepts at work in a sailboat is immensely advantageous, as it can generally improve one’s performance.
