Quoted: Neuroanatomist Jill Bolte Taylor had an opportunity few brain scientists would wish for: One morning, she realized she was having a massive stroke. As it happened -- as she felt her brain functions slip away one by one, speech, movement, understanding -- she studied and remembered every moment. This is a powerful story about how our brains define us and connect us to the world and to one another.

Below is a science fair project that my granddaughter did for 2006. In it she took filtered water and divided it into two parts. The first part she heated to boiling in a pan on the stove, and the second part she heated to boiling in a microwave. Then after cooling she used the water to water two identical plants to see if there would be any difference in the growth between the normal boiled water and the water boiled in a microwave. She was thinking that the structure or energy of the water may be compromised by microwave. As it turned out, even she was amazed at the difference.

Wikiprofessional's Concept Web Initiative is a global collaboration to innovate how knowledge is represented and expanded on the Internet.
The Internet embodies an enormous information space that continues to expand exponentially in page count but not proportionally in new knowledge. Redundancy of the same facts and opinions within a myriad of web-pages has artificially inflated the size of the Internet. To get a million search results on a query without the ability to separate redundancy of the same information from the incremental knowledge expansions on that query concept is highly inefficient. Within the Concept Web, information is converted to streamlined knowledge where redundancy and newness of idea expansion are properly represented.
In the Concept Web, knowledge representation and expansion is accomplished with the aid of two revolutionary technologies: Knowlet and a new professional Wiki.

String theory is a still-developing mathematical approach to theoretical physics, whose original building blocks are one-dimensional extended objects called strings. Unlike the point particles in quantum field theories like the standard model of particle physics, strings interact in a way that is almost uniquely specified by mathematical self-consistency, forming an apparently valid quantum theory of gravity.

Quantum teleportation or entanglement-assisted teleportation is a quantum protocol by which quantum information can be transmitted utilizing a classical communication channel and an entangled pair of qubits. The sender's original qubit is destroyed in the process, as required by the no cloning theorem. The entangled pair of qubits is also separated.
Quantum teleportation does not transport energy or matter, nor does it allow communication of information at superluminal (faster than light) speed, but is useful for quantum communication and computation.
