Alexander Shulgin‚ world renowned biochemist is quoted asking “...but the important question is‚ what isn’t DMT in?”. Its described well by Dr. Rick Strassman‚ the only scientist given permission to study it in the last 40 years as; “The Spirit Molecule”. Many believe this substance‚ which flows through every human’s veins may be a link between the mundane world and spiritual world. DMT use‚ albeit nothing like the pure substance that is used today has been traced back to 8th century Chili

nuclear threat of the Axis powers. On October 11‚ 1939‚ President Franklin D. Roosevelt received a letter from Albert Einstein‚ which Einstein had actually written on August 2‚ 1939. The letter told of a new field of physics that was showing that the element uranium could undergo nuclear fission‚ with the resultant release of a great deal of energy. Einstein described the probability that a sustained nuclear reaction could be produced and the possibility of the construction of extremely powerful bombs

THE CHEMISTRY OF ORGANIC MOLECULES I. MACROMOLECULES-large molecules that are composed of smaller molecules and atoms that are bonded together. These are among the largest of all chemical molecules. A. Polymers-the largest of the macromolecules. These are composed of numerous‚ small identical subunits known as Monomers. There are 4 major polymers that are important for living organisms. These polymers are; carbohydrates‚ lipids‚ proteins and nucleic acids. B. Polymers

1: The atom Introduction Atoms are the building blocks for matter Everything is made up of atoms 1A: Sub-atomic particles Atoms are made up of 3 sub-atomic particles‚ 2 of which are located in the nucleus (the heart of the atom) Positively charges protons and neutrally charged (non-charged) neutrons are found in the nucleus Negatively charged electrons are located orbiting the nucleus in shells. They stay in orbit because the electrons are attracted to the protons 2: The Element

Models of the Atom a) Plum Pudding Model The plum pudding model imagines the atom as a positively charged entity that contains randomly dispersed (negative) electrons within it. It is called the plum pudding model because the electrons in the positively charge cloud resemble raisins in a pudding. Thomson realized that all atoms must contain electrons‚ and since the atoms had a neutral charge‚ they must also include protons. This led him and other to think of the atom as a positively charged

Cloud Model - an atom is comprised of a nucleus made up of neutrons and protons‚ and electrons moving extremely fast around the nucleus‚ forming an electron cloud instead of moving in orbits like what Bohr’s model suggests - proposed by Erwin Schrodinger in 1926‚ when he derived this model using a mathematical equation that he himself made http://1.bp.blogspot.com/-LEqGPr4h8R4/TsgJyT6vP6I/AAAAAAAAAKE/pTl6O3V2u0M/s200/electron_cloud_model.jpg The Planetary/Bohr’s Model - an atom is comprised of
