[View \| Download]	A Theory of Everything: Physics, Chemistry, Biology, & Mathematics. By AlienScientist Welcome to future of humanity. Science is rapidly approaching singularity, as physics has recently formulated a revolutionary new theory of everything which unifies all the fundamental forces in nature under a single force. Nassim Haramein was the first to formulate a unified field theory based upon sacred geometry. Garret Lisi independently formulated a similar theory which showed a complete set of theoretical particles and their interactions with one another when rotated through various charge dimensions. All this arising from a purely geometrical structure called E-8. Critics of this theory have pointed out that some mathematical implications of the E8 Lee Group predict certain gravitoelectromagnetic phenomena that arent observed in nature. However, there are certain scientists who claim these effects do exist in nature, yet their work has been highly criticized by overly aggressive opponents in the scientific arena. Some have even disappeared after having their companies bought out and are now believed to be working for Secret Government Black Operations The most fascinating revelation of this new theory of everything comes with the discrete topological expansion into helical structures of atomic nuclei. If placed in succession these form a Fibonacci spiral based on Phi, the Golden Ratio, another important facet of sacred geometry. This manifests into a new periodic table of elements based on a spiral or cone, instead of Dimitri Mendeleevs table. Walter Russell was the first to arrange the chemical elements in a spiral pattern, yet he failed to connect this to a physical theory of everything. Now that we have this unification it needs to be studied and tested rigorously. I strongly believe that this simple, beautifully elegant explanation is the most illuminating one ever stumbled upon by science and philosophy alike. But Sacred Geometry is nothing new. Our entire DNA, the Double Helix is based upon this same beautiful geometry, and.the more that we study these things and learn about them the closer we will be to understanding the significance behind the underlying nature of the Universe. http://www.helical-structures.org/ANS... http://www.extropedia.org Tags: alienscientist, chemistry, e8, nassim harramein, physics 1 Downloads - Last from: http://downthisvideo.com/ (Your Blog here!)

TEDTalks is a daily video podcast of the best talks and performances from the TED Conference, where the world's leading thinkers and doers give the talk of their lives in 18 minutes. Featured speakers have included Al Gore on climate change, Philippe Starck on design, Jill Bolte Taylor on observing her own stroke, Nicholas Negroponte on One Laptop per Child, Jane Goodall on chimpanzees, Bill Gates on malaria and mosquitoes, Pattie Maes on the "Sixth Sense" wearable tech, and "Lost" producer JJ Abrams on the allure of mystery. TED stands for Technology, Entertainment, Design, and TEDTalks cover these topics as well as science, business, development and the arts.

I made this apparatus simply by inserting a funnel and a glass bend into a 2-hole stopper. In the beginning, hydrochloric acid (HCl) is put into our pH indicator (bromothymol blue) to turn it yellow. This is only a control to compare the carbonic acid results to.

[View \| Download]	How Islamic Inventors Changed The World - Part 2 - [Contribution Of Muslims Series] By returnofthekhera PLEASE CLICK "HQ" TO VIEW A CLEARER VERSION OF THIS VIDEO. In this video I will go over five things invented by Muslims. Please watch Part 1 first and look out for parts 3 & 4. From coffee to cheques and the three-course meal, the Muslim world has given us many innovations that we take for granted in daily life. As a new exhibition opens, Paul Vallely nominates 20 of the most influential- and identifies the men of genius behind them 6 Distillation, the means of separating liquids through differences in their boiling points, was invented around the year 800 by Islam's foremost scientist, Jabir ibn Hayyan, who transformed alchemy into chemistry, inventing many of the basic processes and apparatus still in use today - liquefaction, crystallisation, distillation, purification, oxidisation, evaporation and filtration. As well as discovering sulphuric and nitric acid, he invented the alembic still, giving the world intense rosewater and other perfumes and alcoholic spirits (although drinking them is haram, or forbidden, in Islam). Ibn Hayyan emphasised systematic experimentation and was the founder of modern chemistry. 7 The crank-shaft is a device which translates rotary into linear motion and is central to much of the machinery in the modern world, not least the internal combustion engine. One of the most important mechanical inventions in the history of humankind, it was created by an ingenious Muslim engineer called al-Jazari to raise water for irrigation. His 1206 Book of Knowledge of Ingenious Mechanical Devices shows he also invented or refined the use of valves and pistons, devised some of the first mechanical clocks driven by water and weights, and was the father of robotics. Among his 50 other inventions was the combination lock. 8 Quilting is a method of sewing or tying two layers of cloth with a layer of insulating material in between. It is not clear whether it was invented in the Muslim world or whether it was imported there from India or China. But it certainly came to the West via the Crusaders. They saw it used by Saracen warriors, who wore straw-filled quilted canvas shirts instead of armour. As well as a form of protection, it proved an effective guard against the chafing of the Crusaders' metal armour and was an effective form of insulation - so much so that it became a cottage industry back home in colder climates such as Britain and Holland. 9 The pointed arch so characteristic of Europe's Gothic cathedrals was an invention borrowed from Islamic architecture. It was much stronger than the rounded arch used by the Romans and Normans, thus allowing the building of bigger, higher, more complex and grander buildings. Other borrowings from Muslim genius included ribbed vaulting, rose windows and dome-building techniques. Europe's castles were also adapted to copy the Islamic world's - with arrow slits, battlements, a barbican and parapets. Square towers and keeps gave way to more easily defended round ones. Henry V's castle architect was a Muslim. 10 Many modern surgical instruments are of exactly the same design as those devised in the 10th century by a Muslim surgeon called al-Zahrawi. His scalpels, bone saws, forceps, fine scissors for eye surgery and many of the 200 instruments he devised are recognisable to a modern surgeon. It was he who discovered that catgut used for internal stitches dissolves away naturally (a discovery he made when his monkey ate his lute strings) and that it can be also used to make medicine capsules. In the 13th century, another Muslim medic named Ibn Nafis described the circulation of the blood, 300 years before William Harvey discovered it. Muslims doctors also invented anaesthetics of opium and alcohol mixes and developed hollow needles to suck cataracts from eyes in a technique still used today.
