Blast fishing was introduced in Southeast Asia post World War II, by American soldiers who threw grenades into bodies of water to yield a large cache of fish, a technique which is used during the modern day to produce fish as a food resource in local markets. Dynamite is often used but any explosive will perform the task effectively, even improvised devices which utilize an explosive chemical within a glass drinking bottle with an improvised wick lit by a cigarette. Cyanide fishing is an ecologically destructive method of catching fish in which a diver takes bottled cyanide and pumps it into reef areas where fish reside, stunning the fish and making them easier to catch, so that they can be extracted for the pet and live fish trades. These techniques result in coral reefs losing their color and ultimately dying, eliminating a major food source for marine life within the region. Both methods are extremely damaging to the ecosystem and left unchecked, can decimate entire ecosystems within a few short years. Portions of and entire coral reefs which have slowly built over thousands of years can be destroyed in a matter of seconds by using either of these harmful techniques. Fortunately, both methods of fishing are illegal in most of Southeast Asia

The Etymology of American Industrialist Henry Ford’s Model T Automobile and the First Mass Produced Vehicle
Henry Ford named the iconic Model T automobile as he did because of the way he built his company. Ford started with the Model A and continued to improve the design, moving through each letter of the alphabet the way modern software changes numerically with each upgrade (eg. Model A, Model B, Model C alongside software 1.0, software 2.0, software 3.0 etc.). It was Ford’s 20th design that met his stringent personal requirements allowing the Model T to become the first mass produced vehicle in 1908
The Renewable Resource of Urine Powered Electronics
Urine is rich in minerals and it is believed that this resource will be able to be harnessed and extracted efficiently and cost effectively at some point in the future to produce electrical energy. At the Bristol Robotics Laboratory in the U.K., urine is being studied as a potential energy resource for residential use within the near future (e.g. used to charge a smartphone etc.). Charging a smartphone with urine requires battery like fuel cells with Professor Ioannis Leropoulos (pronounced “yan-iss lee-raw-po-lis”) having developed a system capable of meeting this requirement. The application itself is referred to as “microbial fuel cell” technology, a system which leverages live bacteria to generate electrical current. Urine contains carbon, phosphorus, potassium, sulphur, magnesium, and creatinine, all elements which microbes require to continue living and growing which is why this technology functions as it does. The microbial fuel cell’s central tube is porous ceramic, allowing urine to permeate the tube and microbes to colonize it. As the elements of urine are consumed, electrons generated by the microbes are picked up by the cells of opposing wire coils, creating a battery. Not just any microbe will suffice however, as specific microbes are required for this process to be effective. To source the correct microbes, scientists leverage a plethora of microbes available within the natural environment (e.g. lake, pond, river sediment etc.). Each fuel cell produces 1.5 volts of electrical current, and when linked together in series, output can be increased to a level which is useful for daily activities. The system is able to be scaled so that it can be built into future homes, allowing for individuals and families to recycle urine as a means of generating electrical energy. Leropoulos’ work has been funded by the Bill & Melinda Gates Foundation as well as by the European Commission among others and is close to becoming commercially available as of 2020. For this system to benefit users, separate urinals would be installed but with redirected plumbing to funnel urine away from becoming mixed with common sewage and into a collection container, providing an on demand resource which can be utilized when needed
How Holograms Work
Holograms work by taking a single laser beam and splitting it into 2 parts, with the primary beam falling upon the object being photographed which then bounces away and falls onto a specialized screen, and the secondary beam falling directly upon the screen. The mixing of these beams creates a complex interface pattern containing a three dimensional image of the original object which can be captured on specialized film. By flashing another laser beam through the screen, the image of the original object suddenly becomes holographic. The term “holograph” is derived from the ancient Greek terms ”holo” which means “whole” and “graphos” which means “written”. The main issue with holographic technology is that unlike traditional visual media which needs to flash a minimum of 30 frames per second, scattering the image into pixels, a three dimensional holograph must also flash 30 frames per second, but of every angle to create depth of field, and the amount of data required far exceeds that of a traditional television photograph or video, even exceeding the capability of the internet until recently in 2014 when internet speeds reached 1 gigabyte per second
The Person Who Invented the Internet
Tim Berners-Lee created the internet. Berners-Lee is the son of mathematicians, his mother and father part of a team who programmed the worlds first commercial stored program computer, the Manchester University Mark 1. Berners-Lee developed the original concept for the internet as a young boy, after discussing how machines might one day possess artificial intelligence with his father who was reading a book upon the human brain. Berners-Lee realized that if information could be linked, knowledge which would not normally be associated together, it would become much more useful. Ted Nelson helped expand upon Berners-Lee’s invention by developing the concept of hypertext, a method of digitally linking from one section to another. The development of the internet during the 1960’s became user friendly during the 1990’s as it became increasingly available to the public. Berners-Lee was able to take something which was too complicated for most people to use, and create a system which made it user friendly. Incompatibility between computers had been a thorn in the side of technology for years as specialized cables were needed to ensure computers could communicate with one another. Berners-Lee had the brilliant idea to create a centralized block which all cables would feed into so that one central unit could be used for every computer in the world to communicate. Berners-Lee furthered this idea by designing the concept of anything being linked to anything. A single global information space would be birthed as a direct result of this, a system with common rules, which would be accessible to everyone, that effectively provided as close as possible to no rules at all; a decentralized system. This arrangement would allow a new person to use the internet without having to ask anyone else. Anyone, anywhere, could now build a server and put anything upon it. Berners-Lee decided to name his creation the “World Wide Web” because he thought of it as a global network. Berners-Lee took his intellectual property and provided it to the public free of charge, despite having many commercial offers. Berners-Lee felt that the idea would not become the largest and greatest invention of humanity had it not been free, democratized, and decentralized. The fact that anybody could access the internet and anybody could put content onto it, made the internet massively popular early on and grew at a rate of 10x year upon year. Berners-Lee also created the World Wide Web Consortion, an institution which was designed to help the World Wide Web to develop and grow
The Person Who Invented Ecommerce
Michael Aldrich was an English inventor, innovator and entrepreneur who in 1979, invented the concept of ecommerce, enabling online transaction processing between consumers and businesses. Aldrich achieved this feat by connecting a modified television set to a transaction processing computer which could process purchases in real time via dedicated telephone line. This system entitled “Videotex” had a simple menu driven, human to computer interface, which predated the internet by more than a decade. In 1980, Aldrich invented the Teleputer, a multipurpose home information and entertainment centre which was a combination of the personal computer, television, and telecom networking technologies. Aldrich created the Teleputer using a modified 14” color television which was connected to a plinth containing a Zilog Z80 microprocessor running a modified version of the CP/M operating system and a chip set containing a modem, character generator and auto-dialler. The Teleputer operated as a stand alone, color, personal computer during an era when computer screens were primarily monochromatic. The Teleputer contained software and networking capabilities using dial up or leased telephone lines. The Teleputer system itself included 2 floppy discs, each with 360 kilobytes of memory, later upgraded to a 20 megabyte harddrive, a keyboard, and a printer
The Reason Aritifical Intelligence Differs From Traditional Software
Recently, many of the improvements made within the artificial intelligence sector have been due to the technology of “deep learning” which is also referred to as an “artificial neural network”. Traditional software is not intuitive as it simply follows a set of instructions predetermined by a programmer. If the software runs into a new problem which it has no answer prewritten for, it crashes. Deep learning is different as software can now write its own instructions instead of reading the instruction(s) of a programmer. Currently, as of 2021, deep learning is the equivalent of an all powerful, dim witted genie as it has the ability to evaluate the pixels of a photograph of a bottle of water, and can recognize with astonishing accuracy photographs of other water bottles, however it has no idea what the concept of water or the water bottle itself is, what the end user does to drink from the water bottle, what the end user needs the water for etc. This differs in human beings however as humans learn from a sample size of one, and are able to surmise the purpose of water and everything else which is relevant from witnessing it being used upon a single occasion
The First Advancement of Medieval Gunpowder Technology
To create the earliest form of gunpowder, 3 substances were mixed together which included, sulphur, charcoal, and saltpeter which is comprised potassium nitrate. Because these ingredients have varying specific densities, they constantly separated when mixed, forcing soldiers to re-mix gunpowder after having been transported to the battlefield. By the end of the 15th century, a new technique for the manufacturing of gunpowder emerged, that of corning which made gunpowder much more reliable. Corning involves mixing together the 3 primary ingredients to create a slurry. This is more effective than the traditional method because as the mixture dries, the ingredients do not separate due to their different specific gravities. This acts to increase the stability of gunpowder and allowed cannons to evolve into lethal siege engines no longer governed by the strength of soldiers or the laws of mechanics. Gunpowder, the first chemical explosive ever invented, was the driving force behind the weaponry used against fortifications, hurling projectiles faster, further, and with greater force than previously designed mechanically powered machinery (e.g. trebuchet, catapult, ballista etc.)
The Usage of 5D Crystals as a Means of Computational Storage
Quartz is being used to create the most powerful data storage device ever developed, the 5D Superman Memory Crystal, a technology which could store data for up to 13,800,000,000 (13.8 billion) years, the calculated age of the universe. The 5D quartz crystal is a method of ensuring a large density of data can be saved within a relatively small object. This is an incredibly secure and long lasting method of saving data as the information is physically encoded into the crystal itself, remaining indefinitely until the quartz itself is destroyed, a very difficult task in and of itself. In 2018, technology entrepreneur Nova Spivack used a 5D crystal to create a permanent space library, sending it to the International Space Station aboard the SpaceX Heavy Falcon rocket. Quartz is highly stable because it is a crystal, remaining unchanged for billions of years meaning if data is inserted, theoretically it could survive for billions of years. For a quartz crystal approximately 2.5 centimeters by 2.5 centimeters in diameter and 5 millimeters thick, 30 terabytes of data can be held, which is 30,000 gigabytes or 800 Blu-ray discs or 600 smartphones worth of information. This means that the entire British library could be fit into 1000 5D crystal slides, a small enough volume to fit within a single shoebox. A traditional storage medium like a compact disc, stores data in individual pixels, with 1 pixel able to hold the equivalent of 1 bit or 8 bytes of information. In a quartz drive however, each voxel can hold 8 bits or 64 bytes of information. The technology required to achieve this feat however is still in its infancy with scientists still discovering new ways to refine manufacturing, the writing and reading of data, and storage capabilities
The Comparison of Medieval Gunpowder Explosives toward Modern Day Plastic Explosives
During the modern day, soldiers use plastic explosives to blast through walls, similar to that of the gunpowder powered cannons of antiquity, but different in the sense that they can be directly applied and finely controlled. Despite these differences, the principle of both weaponry remains the same which is to create a powerful burst of kinetic energy to smash apart solid structures. Soldiers with explosive expertise during the modern day plant explosives in a lowercase “i” or “t” shape format by separating the explosives with a gap in the middle. This design ensures the explosive will blow a hole in the top and the bottom of the blast site, as well as the sides in some instances, leveraging the physics of the shockwaves produced to disrupt the wall and weaken it in the middle. Explosive experts don’t attach plastic explosives at the bottom of walls for two distinct reasons, the first being because the foundation upon the other side of the wall which cannot be viewed has the potential to be higher than the foundation facing the impending soldiers, which means that the explosives would be blasting into solid ground soil which is much less effective than blasting into walls made of concrete or otherwise, and the second being that explosives close to the ground create rubble directly next to the hole created, making forced entry more difficult, especially under siege conditions with active enemy combatants attempting to stop the breach. The main difference between Medieval gunpowder and modern day plastic explosive is the amount of material required to produce the same effect as plastic explosives are an entire order of magnitude more powerful than gunpowder, with 2 kilograms of plastic explosive equating to multiple barrels of gunpowder. Explosives are categorized as either “high explosives” or “low explosives” with high explosives having the front of the chemical reaction travel faster than the speed of sound and low explosives having the front of the chemical reaction produced travel slower than the speed of sound. To provide comparison, modern day C4 plastic explosives have a detonation velocity of 8,092 meters per second whilst gunpowder has a detonation velocity of just 171 – 631 meters per second
