If electron moved in a definite orbit, would that violate Heisenberg uncertainty principle?
Does electron orbital theory contradict the Heisenberg uncertainty principle?

Is there a way to make them wider? How can I manage computers using my Firefox Sync account? I`m using Firefox Sync on a bunch of computers.   I would like to manage my account, by removing some computers. I can't find the place to do this, it should be on the Firefox Sync page, but the official page only has the privacy and download information. How can I remove a trailing newline? What is the Python equivalent of Perl's chomp function, which removes the last character of a string if it is a newline? How to remove extra start item from boot menu? I bought a laptop recently. While Windows 7 was installing, the battery died. So I plugged in the charger and re-installed Windows 7 Home Basic from the start. After completion of the procedure I now have 2 Windows folders in my C:\ drive, so I deleted the old Windows folder.  The problem is, while booting time it shows two Windows 7 options, although I already deleted the old Windows folder.  How can I remove old Windows 7 option from my boot? CSS selector for first element with class Types of polynomial functions. Quadratic, cubic, quartic, quintic, ...,? I would very much like to have a complete list of the types of polynomial functions. I know that theres:  Quadratic :                      (AX^2 + BX + C) Cubic     :               (AX^3 + BX^2 + CX + D) Quartic   :        (AX^4 + BX^3 + CX^2 + DX + E) Quintic   : (AX^5 + BX^4 + CX^3 + DX^2 + EX + F)   What are the names of polynomial functions to the further powers? Sexstic? Septic? Octic? I'm not sure, so if someone could enlighten me, then that would be great. Please provide a list that goes at least to the seventh power, but it would be nice if you could go further. Thanks. This seems to be quite a trivial problem, but after some searching I can't stil figure out the answer. One can run tcpdump using "any" as the interface description, ie:   # tcpdump -i any -n host 192.168.0.1   Is there any way to force tcpdump to show on which interface displayed packet was captured?  Update:  As more people confirmed this is probably not possible with vanilla tcpdump, can someone propose a solution to mentioned problem? Perhaps different sniffer?   General issue is as follows: On a system with 50 interfaces determine what is inbound interface for packets coming from specific ip address. How to make the function of the planes from the lorenz attractor Date Not Saving in Mysql from Php Registration Form Here $p$ and $q$ are co-prime integers. Is it necessarily an algebraic number? Extracting usernames from the /etc/passwd file Singularities in the punctured unit disc and square integrability I'm having trouble with the following problem:  Let $f$ be holomorphic on the punctured unit disc, $D$. If $\int_D|f(z)|dA(z)&lt;\infty$, then $z=0$ is either a removable singularity or a simple pole of $f$.  A similar problem is to prove or disprove that if $\int_D|f(z)|^2dA(z)&lt;\infty$, then $f$ has a removable singularity at $0$.  I've tried using the Mean Value Property for $f$ and taking the limit as $z\to0$, but I didn't get anywhere. Negative pressure The differences between TeX engines Is it possible to use a MacBook Pro as a second monitor for my iMac? Both of them have a Thunderbolt port.  If not, is there any other way? I'm trying to delete a folder in Windows 7 and get a perplexing error message: "Could not find this item:  This is no longer located in G:\Graphics.  Verify the item's location and try again.  I can see the folder -- I can find it.  I just can't delete it.    I also get a second error message (sometimes) when I click on the folder: G:\Graphics 2009-11-17 refers to a location that is unavailable...this information might have been moved to a different location.    I'm using Windows 7; this folder is on an external hard drive.  I've emptied the folder (there were items in it); I've scanned that external hard drive for errors.  Trying to rename the folder yields the same enigmatic error message.    Is there a way to delete this folder? There are two schools of thought on how to best extend, enhance, and reuse code in an object-oriented system:   Inheritance: extend the functionality of a class by creating a subclass. Override superclass members in the subclasses to provide new functionality. Make methods abstract/virtual to force subclasses to "fill-in-the-blanks" when the superclass wants a particular interface but is agnostic about its implementation. Aggregation: create new functionality by taking other classes and combining them into a new class. Attach an common interface to this new class for interoperability with other code.   What are the benefits, costs, and consequences of each? Are there other alternatives?  I see this debate come up on a regular basis, but I don't think it's been asked on  Stack Overflow yet (though there is some related discussion). There's also a surprising lack of good Google results for it. Checking for sublist in list In chapter 1, of Landau-Lifshitz Mechanics' book, Landau through isotropy and homogeneity of space and homogeneity of time proves that the Lagrangian must depend of magnitude of velocity of the particle.  This seemed fine. But he didn't give a reason as to why it must depend of $|v|^2$ and not on some $|v|^n$ where $n\neq2$.
