http://www.encognitive.com In quantum physics, the Heisenberg uncertainty principle is the statement that locating a particle in a small region of space makes the momentum of the particle uncertain; and conversely, that measuring the momentum of a particle precisely makes the position uncertain. In quantum mechanics, the position and momentum of particles do not have precise values, but have a probability distribution. There are no states in which a particle has both a definite position and a definite momentum. The narrower the probability distribution is in position, the wider it is in momentum. Physically, the uncertainty principle requires that when the position of an atom is measured with a photon, the reflected photon will change the momentum of the atom by an uncertain amount inversely proportional to the accuracy of the position measurement. The amount of uncertainty can never be reduced below the limit set by the principle, regardless of the experimental setup. A mathematical statement of the principle is that every quantum state has the property that the root-mean-square (RMS) deviation of the position from its mean (the standard deviation of the X-distribution): Delta X = sqrt{langle X^2 rangle-langle X rangle ^2 } , times the RMS deviation of the momentum from its mean (the standard deviation of P): Delta P = sqrt{langle P^2 rangle-langle P rangle ^2} , can never be smaller than a small fixed multiple of Planck's constant: Delta X Delta P ge {hbar over 2} The mathematical statement implies the physical statement. Once an observer measures the position of a particle with accuracy ΔX, the state of the particle immediately after the measurement has scriptstyle Delta P ge hbar /(2Delta X) . The uncertainty principle is related to the observer effect, with which it is often conflated. In the Copenhagen interpretation of quantum mechanics, the uncertainty principle is a theoretical limitation of how small this observer effect can be. A precise position measurement must alter the momentum by a large indeterminate amount, and vice-versa. While this is true in all interpretations, in many modern interpretations of quantum mechanics (many-worlds and variants), the quantum state itself is the fundamental physical quantity, not the position or momentum. Taking this perspective, while the momentum and position are still uncertain, the uncertainty is an effect caused not just by observation, but by any entanglement with the environment. http://en.wikipedia.org/wiki/Uncertainty_principle Author: TrungEdm Keywords: Heisenberg uncertainty principle physics quantum mechanics Added: April 21, 2008

FAP696: Understanding What an Investment Is Listen now: Student Financial Aid News + Inside Higher Ed: Haverford College announced Wednesday that it is moving to replace all loans in students aid packages with grants. At the same time, the college is creating a new endowment fund and asking (but not requiring) students who benefit from the change to pledge gifts to assure that future generations of students have the same opportunity to avoid loans. Tufts University on Wednesday announced that it would replace loans with grants for students from families with incomes up to $40,000. + Chronicle: The U.S. House of Representatives approved this afternoon a $555-billion budget package for 2008 that includes less-generous amounts for academic research and student aid than previous bills favored by Democratic leaders in Congress had contained. The sprawling measure, which the Senate passed on Tuesday, now heads to President Bush, who is expected to sign it. + Passage of the bill follows a month of tense negotiations between Congress and the president, who refused to sign any bill that exceeded his budget request. Ultimately, lawmakers were forced to shave millions of dollars from their proposed appropriations for domestic programs. Among the cuts: nearly $1-billion from the budget for the National Institutes of Health, which is the largest single source of funds for university research. + Under the bill, HR 2764, the maximum Pell grant, which is now $4,310, would be trimmed to $4,241, although the actual award would rise to $4,731 once funds from a student-aid bill enacted in September are included. The earlier measure provided enough money for a $490 increase above the maximum in the bill approved today. The new omnibus appropriations bill would finance every federal agency except the Pentagon for the 2008 fiscal year, which began October 1. + Funds for the TRIO and Gear Up programs, which prepare low-income students for college, would be frozen at 2007 levels, while spending would drop on several other student-aid programs, including Supplemental Educational Opportunity Grants, Perkins Loans, and the Leveraging Education Assistance Program, or LEAP. + IndyStar: Last Friday the day he was renamed chief executive of Sallie Mae Lord had to sell a whopping $34.6 million worth of his personal stock in the student loan giant to cover an unspecified loan. Then on Wednesday, shares plummeted 21 percent in value after Lord told analysts on a conference call the beleaguered company would consider reducing its dividend payment. To top it off, Lord wrapped up his rambling and, at times, tense conference call by dropping a four-letter bomb. + When an analyst asked how much equity it would take to improve Sallie Mae s credit rating, Lord said, You re talking to the wrong guy. I don t know that answer. Lord told analysts he would answer questions in full at a company meeting in January. The call ended with Lord saying, There s no more questions, let s get the (expletive) out of here.

FAP621: Economics 101: Risk Can Be Managed - Uncertainty Cannot, Bree NobleOne of my favorite podcasts to listen to is Bloomberg on the Economy, published by megalithic financial services company Bloomberg LP. It's a great, often dense series of interviews with prominent economists, public figures, etc. Recently, Jacob Frenkel of insurance giant AIG had an insightful way of talking about risk.Risk is a probability of something happening, and then your ability to deal with that risk. There is always a probability of rain, as an example. Some days, that probability is very close to (but never) zero. Some days, that probability is close to 100%. Which end of the risk spectrum of rain determines whether you carry an umbrella. Whether you choose to carry an umbrella or not is your comfort with risk vs. opportunity cost. If you're incorrect at judging risk conservatively (10% chance of rain? Holy cats, it's the Great Flood!), you carry an umbrella on days when you don't need it. If you're incorrect at judging risk aggressively (90% chance of rain? But it never rains on Wednesdays!), you get rained on more often than you should.Frenkel points out that risk is entirely manageable, and therefore subject to rational thinking. Generally speaking, risk is expressed in the form of a percentage. If you say something is risky but can't express it in terms of a percentage, it's probably not a risk, or you're uncertain.Uncertainty is a different animal. Uncertainty is when you don't know what the risk is - you simply have insufficient data. Again, with the weather, if you don't listen to the forecast and you don't look out the window, judging the risk of rain is a great deal harder to do. It's much easier to make poor choices with a lack of information, and therefore uncertainty is a dire enemy in any situation in which you have to assess risk. Uncertainty can also come from poor quality data, or data that is irrelevant. Ed Roberts' Kansas City Weather Podcast is extremely poor quality data - if you live in Boston, as I do. It's great for assessing risk in Kansas City, but it just creates uncertainty in Boston.When you're considering whether to make a move or not, whether to quit a job or not, whether to make a choice or not, ask yourself - are you making a rational choice based on risk, or are you taking a shot in the dark because you're uncertain?Promo+ Student loan consolidation with StudentLoanConsolidator.comPodsafe Music+ Bree Noble, Risk It AllReminders+ Add the show to your iTunes by visiting http://www.FinancialAidPodcast.com/itunes/+ Register for PodCamp Boston for free+ Private student loans available at any time - visit AlternativeStudentLoan.com+ Stafford federal student loans at StaffordLoan.com+ Student loan consolidation at StudentLoanConsolidator.com+ FAFSA form tutorials and free help at FAFSAonline.com+ Financial Aid Podcast Show Notes at FinancialAidPodcast.com.+ The Financial Aid Podcast is a publication of the Student Loan Network.I want to hear from you!
