Tech Your Head essays

Tech Your Head essays Growth in technology is very similar to evolutionary growth. Our world has seen so much change since life first sprouted on our planet. Since the primordial soup of earths prehistoric waters created organisms life on earth has progressed quickly. Much like evolutionary processes found in life forms, technology builds on its own increasing order and thus speeds up. The technological developments of modern-day computer scientists will bring us computers faster than weve ever seen, a new intelligent life-form with mental powers equal or surpassing our own, and will raise moral and ethical questions currently unforeseen. Gordon Moore, the inventor of the integrated circuit, noted that the surface area of a transistor was being reduced by 50 percent every 12 months. When he made this observation he was chairman of Intel. Then, in 1975, he revised his observation to 24 months. With a biannual doubling of the number of transistors that you can fit onto an integrated circuit, the components on a chip as well as the speed of the computer are doubled. The idea of exponential growth in technological developments is known as Moores Law on Integrated Circuits. Almost all of the developments made in calculation technology from the abacus to the Apple II have laid appropriately on the timeline of technological evolution as prescribed by Thomas Moore, but now it seems there has been a recent acceleration in the acceleration of the evolution. Today, we use computers to design computers, and they meticulously calculate details in the newest design, then the designs are produced in factories that utilize full automation with very little intervention from humans. We can expect that computers will take their progression into their own hands, and at that point they will accelerate very rapidly. According to Ray Kurzweil, a highly educated and experienced man in the field of nanotechnology as well as the author of ...

Daltons Model of the Atom and Early Atomic Theory

Dalton's Model of the Atom and Early Atomic Theory You may take it for granted that matter is made up of atoms, but what we consider common knowledge was unknown until relatively recently in human history. Most science historians credit John Dalton, a British physicist, chemist, and meteorologist, with the development of modern atomic theory. Early Theories While the ancient Greeks believed atoms made matter, they disagreed on what atoms were. Democritus recorded that  Leucippus believed atoms to be small, indestructible bodies that could combine to change properties of matter.  Aristotle believed elements each had their own special essence, but he did not think the properties extended down to tiny, invisible particles. No one really questioned Aristotles theory, since tools did not exist to examine matter in detail. Along Comes Dalton So, it wasnt until the 19th century that scientists conducted experiments on the nature of matter. Daltons experiments focused on gases their properties, what happened when they were combined, and the similarities and differences between different types of gases. What he learned led him to propose several laws, which are known collectively as Daltons Atomic Theory or Daltons Laws: Atoms are small, chemically indestructible particles of matter. Elements consist of atoms.Atoms of an element share common properties.Atoms of different elements have different properties and different atomic weights.Atoms that interact with each other obey the Law of Conservation of Mass. Essentially, this law states the number and kinds of atoms that react are equal to the number and kinds of atoms in the products of a chemical reaction.Atoms that combine with each other obey the Law of Multiple Proportions. In other words, when elements combine, the ratio in which the atoms combine can be expressed as a ratio of whole numbers. Dalton is also known for proposing gas laws (Daltons Law of Partial Pressures) and explaining color blindness. Not all of his scientific experiments could be called successful. For example, some believe the stroke he suffered might have resulted from research using himself as a subject, in which he poked himself in the ear with a sharp stick to  Ã¢â‚¬Å"investigate the humours that move inside of my cranium.†
