Forecasting: Extrapolation and Projection by D. James Benton (3 Reviews)    Price verified 2 hours ago

Forecasting has many applications besides tomorrow's weather, from business to medicine to economics. There are many diverse methods and approaches taken to accomplish this task and achieve the desired end: reliable expectation. Predicting the future behavior of some processes can be much more difficult than others. In this text we will consider only those expectations that can be expressed quantitatively and for which there are existing observations. We will not consider "events" per se, especially singular ones, such as the next stock market crash or nuclear war. We will also not consider computational models which are simply run out into the future, such as is done with the weather, as these approaches are not transferable. All of the data, spreadsheets, and software are available free online.

EINSTEIN - ROSEN BRIDGE NOW PROVEN: WORMHOLE ALLOWS ENTIRE PERSON TO TRAVEL by Johnny Vincento (6 Reviews)    Price verified 5 hours ago

For Students and Peer Review. OR THE GREATEST GIFT A SCIENCE PERSON COULD EVER RECEIVE. Greetings Fellow and Future Scientists. GREETINGS TOP SCIENTISTS OF THE WORLD... A project 20 years in the making brings humanity a new understanding of what reality is. Science fiction writers have brainwashed the public to think that a machine can Teleport a person from point A to point B. Once science understands the real quantum physics of Teleportation, then science can pursue many goals. The STEERING of the Wormhole was not understood for practically the entire 20 years. The "Quantum Entanglement Silver Cord Wormhole" now has very precise STEERING. FOR THIS REASON A TEST CAN BE PERFORMED TO VISIT OTHER PLANETS WITH INTELLIGENT LIFE For this reason also, "ACTUAL TIME TRAVEL" can be attempted.. It is not the physical body that goes through the Wormhole, but one's Life Force. Once through, the person Teleporting is DUPLICATED, thus making two of the person. There is no distance to travel when crossing dimensions. Space is folded as in the Einstein - Rosen Bridge. However, that model is replaced with this working two way Bridge. It has been debated that the Duplicate person or duplicated Particles as in Quantum Entanglement are either an opposite or a mirror duplication or an exact duplication but not both. To add what connects the two physical bodies through "Spooky Action from a distance?" To satisfy this question, the duplicated person is both exact and opposite at the same time. Connected by the Silver Cord. For the original person on Earth is Mortal and the duplicated person is exact and immortal. A secondary project would actually have to be a machine. This would be something that was never attempted by man: A "Dimension Separation Viewer.". This will be a window between overlapping worlds, occupying the same space, unseen due to Dimensions and accessed through Teleportation or a D.S.V. machine... NOT FICTION..
