    How I Scored a 180 on the LSAT

    Wednesday, May 14th, 2008

    One of the most important steps to getting a high LSAT score happens before you ever open a book to begin studying. The test date you choose can have a significant impact on how high you score. To understand the importance, you should know that all LSAT scores are sent to the law schools to which you are applying. This means that law schools will see every LSAT score you have taken, your best, your worst, and everything in between. Due to this score reporting, it is advisable you only take the LSAT once, and make your one score count. The best time to take the LSAT is the June before your senior year. Taking the test in June means that you are far along enough in your studies, yet you still have plenty of time to apply, and you get the advantage of taking the test during the summer, when you are on a break from school. While the October test date is still early enough to apply for law school, it also falls around the time of midterms, and you could find yourself stressed and ill-prepared to take the LSAT in the middle of the school semester when so many exams and papers are taking up your time.

    Take your first practice test long before you take the LSAT. Three to six months before June, schedule a saturday where you will wake up early, sit down at your desk, and take a practice test under the exact same conditions as the real LSAT. Buy a small, cheap, kitchen timer from the store and set each section’s time exactly. Only allow yourself the allotted time, and don’t stop or get distracted. You can easily download practice test online, or buy books with multiple tests. This first practice test will help you see what score you would make with no studying, and thereby tell you how hard you need to study to get the score you want. Most importantly, this test will tell you which section you need the most work on. More than likely you will not have an infinite amount of time to study for the LSAT, so you need to use your time effectively and spend the most time on the sections you score the lowest on. The national average LSAT score is 150, so you want to strive for over 150.

    Use the data from your first practice test and take more practice tests. If your worst score was in Analytical Reasoning, take that section of practice tests many times. As you complete each practice test you will learn how the questions are structured so that you can answer them faster. You will also start to understand how the tests are scored, so you will learn which answers are correct. Additionally, you will become familiar with the test so that on test day, you are confident and calm. Continue taking individual sections as practice tests until you are happy with the score. Remember that the LSAT is not about memorizing facts. Therefore, you don’t need to study books or notes. The LSAT tests your thinking skills. The best way to improve these skills is with practice.

    The final step in achieving the LSAT score of your dreams is in understanding the scoring of the test. Each test has approximately 101 questions. Your score is based on the number of questions you answer correctly. This means you are not penalized for guessing. You should answer every question, even if you don’t know the answer. Always make an educated guess if you don’t know the answer. This also means every question is given the same weight. If one question has you stumped, circle it and move on. When you are done, go back to the questions you have circled and try to answer the questions that will require the least amount of time first.

    Newton’s Laws Apply Directly To The Function Of A Bullwhip, Or Any Other Whip For That Matter

    Tuesday, May 13th, 2008

    Newton’s First Law Every object in a state of uniform motion tends to remain in that state of motion unless an external force is applied to it. This we recognize as essentially Galileo’s concept of inertia, and this is often termed simply the “Law of Inertia”.

    Newton’s’ Second Law The relationship between an object’s mass m, its acceleration a, and the applied force F is F = ma. Acceleration and force are vectors in this law the direction of the force vector is the same as the direction of the acceleration vector. This is the most powerful of Newton’s three Laws, because it allows quantitative calculations of dynamics: how do velocities change when forces are applied. According to Newton, a force causes only a change in velocity (an acceleration); it does not maintain the velocity. This is sometimes summarized by saying that under Newton, F = ma. According to Newton an object with a certain velocity maintains that velocity unless a force acts on it to cause an acceleration (that is, a change in the velocity). Or in the case of a whip the mass decreases.

    Newton’s Third Law For every action there is an equal and opposite reaction. I think this is probably self explanatory.

    Now if we add Galileo’s findings on inertia (see below) We have a complete real world explanation of the action of a whip. Galileo’s concept of inertia: an object in a state of motion possesses an ” inertia” that causes it to remain in that state of motion unless an external force acts on it. In order to arrive at this conclusion, which will form the cornerstone of Newton’s laws of motion (indeed, it will became Newton’s First Law of Motion), Galileo had to abstract from what he, and everyone else, saw. Most objects in a state of motion do NOT remain in that state of motion. For example, a block of wood pushed at constant speed across a table quickly comes to rest when we stop pushing. Galileo, by virtue of a series of experiments (many with objects sliding down inclined planes), realized that you must account properly for a hidden force: the frictional force between the surface and the object. Thus, as we push the block of wood across the table, there are two opposing forces that act: the force associated with the push, and a force that is associated with the friction and that acts in the opposite direction. (In the case of a whip this would be friction from the air and the inherent resistance of the material of the whip.) Galileo realized that as the frictional forces were decreased (for example, by placing oil on the table or in the case of a whip the mass is reduced) the object would move further and further before stopping. From this he abstracted a basic form of the law of inertia: if the frictional forces could be reduced to exactly zero (like reducing the mass and diameter of the the whip to almost zero) an object pushed at constant speed across a frictionless surface of infinite extent will continue at that speed forever after we stop pushing, unless a new force acts on it at a later time. Here the new force would be your hand holding the end of the whip or gravity.

    Hope this helps in understanding the physics of the whip.

    E=mc2 is Wrong - Einstein’s Special Relativity Fundamentally Flawed

    Monday, May 12th, 2008

    Is Albert Einstein’s Special Relativity incompatible with the very equations upon which science’s greatest theory is built? New observations made by many scientists and engineers appear to contradict the great scientist’s ideas. Apparently there are implicit contradictions present within Relativity’s foundational ideas, documents and equations. One individual has even pointed that quotations from the 1905 document and Einstein’s contemporaries as well as interpretations of the Relativity equations clearly and concisely describe a confused and obviously erroneous theory. It is time therefore, for science to update its thinking on this theory with a comprehensive analysis of the history leading up to, during and after that revolutionary year of Special Relativity.

    As this is the 100 year anniversary of the original release of Special Relativity, a review of the original assumptions, documents and ideas which led to the acceptance of this theory is timely and warranted. Every year millions of students are taught this theory without a critical analysis of Relativity. Relativity Theory consists of its two variants Special Relativity and General Relativity and is considered the cornerstone of modern physics.

    Albert Einstein borrowed from the ideas of Fitzgerald, Lorentz and Voigt to create a new concept of the universe. His first work in this regard later came to be known as Special Relativity and contained many controversial ideas which today are considered axiomatic. Amongst these are Length Contraction, Time Dilation, the Twin Paradox and the equivalence of mass and energy summarized in the equation E=mc2.

    This equation became the shining capstone of the new theory along with its first & second postulates, namely, that the laws of nature are the same from all perspectives and that the speed of light ‘c’ is constant in a vacuum regardless of perspective. Further, the theory also predicted an increase in mass with velocity. Numerous examples have been given of the ‘proof’ of the validity of Special Relativity.

    Most notably, experiments using particle accelerators have sped particles to incredible velocities which apparently provide confirmation of Einstein’s theory. However, doubts remain in the scientific community who have never totally given up the comfort of a Newtonian world view. This is readily apparent in that they refer to the Newton’s ‘Law’ of Gravitation whilst Special Relativity (SR) and General Relativity (GR) are given the polite attribution ‘The Theory of’ or simply SR ‘theory’ and GR ‘theory.’ Einstein would continue working on the ideas of Special Relativity until producing the aforementioned even more controversial treatise.

    In his later more comprehensive work called the Theory of General Relativity (1916), Einstein proposed a major re-thinking of cosmology. He conceived of a space time continuum that is curved by mass; in other words, planets, stars, galaxies and other stellar objects cause a curvature of space time. The movement of these objects are determined by the aforementioned curvature.

    As a result of these ideas, our understanding of geometry, math, physics, science and the universe would never be the same. However, some scientists are reporting that speed of light is not constant from different experimental observations. One has even reported errors in the fundamental equations. If so, this would require a major rethinking of the known cosmological models and assumptions of modern physics.
