- 81: Atomic Bomb 5
- ... bloodiest battles of World War II, which took place at Okinawa. If allowed to expand, Japan posed a serious threat to the allies. During the war, one of the most brilliant scientists in history, Albert Einstein, hypothesized that if the true power of the atom were released in a weapon, the results would be devastating. This was soon confirmed by a large portion of the scientific community. Whoever possessed such a ... the energy required to keep the nucleus together) in the nucleus of the radioactive atom. The bombardment of one nucleus sets off a chain reaction that lasts until all radioactive atoms have been split. Albert Einstein was able to calculate the amount of energy in a sample with his famous equation E=mc^2 . Using this equation, the amount of energy in 1 gram of a substance can be found: 1 ...
- 82: Interstellar Travel: Sooner or Later?
- ... or Later? Though interstellar travel is theoretically possible, colonizing Alpha Centauri in the next millennium may be far-fetched. Modern Quantum physics gives many new openings into the world of plus-light-speed travel, but Einsteins theory of relativity maintains the fact that light speed is an paradoxical and impossible feat for anything other than light and electricity. Science is rapidly and constantly advancing, recently many scientists and physicists have ... Though interstellar travel is theoretically possible, colonizing Alpha Centauri in the next millennium is far-fetched. Modern physics and technology just do not provide for such feats of energy and control of physics. Physicists like Einstein, Hawkings, Von Braun, and Sagan have given us a good step forward in technology and theory, but it is time for a new generation of great minds to take the research even further. With the ...
- 83: Max Planck
- ... theory of quantum he was forty-two and then later won the Nobel Prize for physics in 1918. After his discovery he still contributed to physics increasingly. Planck was the first physicist to back up Einstein's theory of relativity. After he retired as a physicist which was around the time Hitler rose to power Planck focused on philosophical and questions of faith in his writings. During the World War I ... war ended Max Planck lost the will to live and died of natural causes on October 4, 1947 when he was eighty-nine. Plack's contributions to the modern world are vast. He led Albert Einstein towards the theory of relativity which led to the construction of the atom bomb. That is one huge example of the things Max Plank made possible by discovering quantum theory.
- 84: What is Physics?
- ... Isaac Newton in his book Principia Mathematica Philosophiae Naturalis (1686). Newtons laws of motion and gravitation were sufficient to describe almost all motion of practical interest for over two centuries until 1905, when Albert Einstein proposed his theory of relativity. Einsteins mechanics extended Newtonian dynamics, to include motion at speeds approaching that of light. Later, Max Planck, Werner Heisenberg, and others developed quantum mechanics, to describe motion on a subatomic scale. Bibliography 1. 1998 Grolier ...
- 85: Atoms
- ... idea for the atom. His model, called the raisin dough model had positive and negative particles imbedded into a positive atom. Other particles in the atoms nucleus were discovered after the electron thanks to Albert Einstein. In his theory of relativity, proposed in 1905, Einstein developed the equation E=mc2, with E representing energy, m representing mass and c representing the velocity of light. This meant that because the nucleus made up such a large percentage of a atoms mass ...
- 86: Mahatma Gandhi
- Mahatma Gandhi (Mohandas Karamchand) "Generations to come will scarce believe that such a one as this ever walked upon this earth in flesh and blood". -Albert Einstein Throughout history most national heroes have been warriors, but Gandhi was a passive and peaceful preacher of morals, ethics, and beliefs. He was an outsider who ended British rule over India without striking a blow ... never earned a degree or received any special academic honors. He was never a candidate in an election or a member of government. Yet when he died, in 1948, practically the whole world mourned him. Einstein said in his tribute, "Gandhi demonstrated that a powerful human following can be assembled not only through the cunning game of the usual political maneuvers and trickery but through the cogent example of a morally ...
- 87: Leonard Bernstein
- ... Bernstein said that his marriage was holding him back from being the best artist he could be. When Mrs. Bernstein became seriously ill, though, they were reconciled. Bernstein has received such awards as the Albert Einstein Commemorative Award in the Arts from the Albert Einstein College of Medicine; the John H. Finley Medal for service to New York City; the Golden European trophy, an annual award given to an outstanding figure in popular music; the Datsun Award for outstanding service ...
- 88: A Brief History Of Time: A Review
- ... the universe was born. Now, in the incisive style which is his trademark, Professor Hawking shows us how mankind's "world picture" has evolved from the time of Aristotle through the 1915 breakthrough of Albert Einstein, to the exciting ideas of today's prominent young physicists. Was there a beginning of time? Will there be an end? Is the universe infinite? or does it have boundaries? With these fundamental questions in ... reviews the great theories of the cosmos -- and all the puzzles, paradoxes and contradictions still unresolved. With great care he explains Galileo's and Newton's discoveries. Next he takes us step-by-step throught Einstein's general theory of relativity (which concerns the extraordinarily vast) and then moves on to the other great theory of our century, quantum mechanics (which concerns the extraordinarily tiny). And last, he expores the worldwide ...
- 89: B E C: The New Phase of Matter
- B E C: The New Phase of Matter A new phase of matter has been discovered seventy years after Albert Einstein predicted it's existence. In this new state of matter, atoms do not move around like they would in an ordinary gas condensate. The atoms move in lock step with one another and have identical ... to research the mysterious properties of quantum mechanics. It was named "Molecule of the Year" because it was such a major discovery, but it is not a molecule at all. The phase, called the Bose-Einstein condensate (BEC) follows the laws of quantum physics. In early 1995, scientists at the National Institute of Standards and Technology and the University of Colorado were the first to uncover the BEC. They magnetically trapped ...
- 90: Paul Adrien Maurice Dirac
- ... still untested because his theoretical work was so far reaching, but many other predictions have been verified, assuring him of a special place in the history of physics.[6] Dirac was three years old when Einstein published his famous papers on relativity in 1905 and a year old when his predecessor Joseph Larmor began his tenure as Lucasian professor. Physics had just begun its incredible transformation of the twentieth century when ... thought about the world around us, and in part because it was a difficult problem. The important developments of the beginning of this century were carried out by Max Plank, Max Born, Niels Bohr, Albert Einstein, Werner Heisenberg, Erwin Schrodinger, and Wolfgang Pauli. Quantum mechanics was brought to life during the few short years of 1925 through 1927 by most of these men.[11] Dirac was the first to apply quantum ...
