In my mind the multiverse theory is at this point‚ equally as possible as God or a Creator setting the parameters we live in that allow the existence of life. Being as it is unproved and almost impossible to prove at this time; the theory’s that explain the knife edge of probability’s that we live in brings scientists to believe is some ways there own form of

In the United States today people from all corners of the earth come together to form a melting pot. It can be described as a mesh of diversity which melds together to form a unique nation. The uniqueness of this country can best be attributed to by the contributions made by each of the different cultures that call it home. While many of these contributions may go unnoticed some have vastly changed the lifestyles of those who inhibit this land. As it remains well documented the first inhabitants

THE MOLE A mole (symbol Mol) is the base unit of quantity of a substance in the metric system. A mole is the quantity of a substance that contains 6.02 x 1023 units. A "unit" is the smallest measurable entity in the substance‚ generally either an atom or a molecule. The number of units in a mole was determined by Italian chemist (a scientist specializing in the composition‚ structure‚ properties‚ and reactions of matter) Amedeo Avogadro (1776-1856)‚ one of the founders of modern physical chemistry

ECET345 Signals and Systems Homework #4 Name of Student ______________________________ 1. A shiny metal disk with a dark spot on it‚ as shown in figure below‚ is rotating clockwise at 100 revolutions/second in a dark room. A human observer uses a strobe that flashes 99 times/second to observe the spot on the metal disk (a strobe is a flashing light whose rate of flashing can be varied). The spot appears to the human observer as if it is rotating slowly. Hint: This is equivalent

Not everyone is a tech enthusiast. Thus‚ the ultimate decision between a Mac and PC can be overshadowed by the constant rivalry between Apple and Microsoft. The truth is that Macs and PCs are very different‚ but similar at the same time. However‚ one of these systems will fit a person’s needs and wants better than the other one. When any person or company in the world is in the process of buying new computers or laptops for personal‚ school‚ or office use‚ they might not know which system to buy

It emphasizes the human condition of being alone and helpless in the face of love‚ life and death. Love is powerless in the face of death. All of its complicities

phenolphthalein? Introduction Diffusion is a process where the molecules intermingle as a result of their kinetic energy of random motion and is the net movement of like molecules down their concentration gradient‚ which is the energy inherent in their constant molecular motion makes them collide and careen outward from the region of higher to lower concentration. In our daily lives‚ many tasks are accomplished with the help of diffusion. For example‚ farting is considered to be diffusion‚ releasing
