The Reference Frame: Eichler et al.: Half of recent warming was solar

http://motls.blogspot.com/2008/12/eichler-et-al-half-of-recent-warming.html

Supersymmetric world from a conservative viewpoint. Wednesday, December 10, 2008 . Eichler et al.: Half of recent warming was solar. In this dose of peer-reviewed. Skeptical climatological literature, we follow Climate Research News. The blog was intrigued by a new article in Geophysical Research Letters. That was accepted on Friday, December 5th. Eichler, A., S. Olivier, K. Henderson, A. Laube, J. Beer, T. Papina, H. W. Gäggeler, and M. Schwikowski. Revealing that only up to approximately 50% of the obs...

They show the 'interactions' between the poles of a particular retarded Green's function as temperature and momentum are varied. All plots are for the ( hat{ Pi} {-} ) correlator on the complex ( omega/ mu )-plane. Fixed temperature and increasing momentum: click here. T/ mu = 0.09 quad , quad 0.03125.

Exploring the Mountain: The Wave Function 05

http://physicsfromthebottomup.blogspot.com/2014/05/the-wave-function-05_29.html

Noli turbare circulos meos. Thursday, May 29, 2014. The Wave Function 05. Mdash; 1.6. The Uncertainty Principle —. Imagine now that, instead of just producing one jerk, you continuously wave the rope so that you end up producing a standing wave. In this case the wavelength is perfectly defined, since this a phenomenon that is periodic, but the wave position loses its meaning. Quantum mechanics, as we'll see in later posts, asks for a particle description that is given in terms of wave packets. In a more ...

Exploring the Mountain: What is this all about?

http://physicsfromthebottomup.blogspot.com/2009/02/plan.html

Noli turbare circulos meos. Thursday, February 12, 2009. What is this all about? On my other blog. On Wordpress I have a pretty clear and definite plan. On that blog I'll write up my class notes, and other resources, with the goal of re-studying and having a stronger and more united grasp of physics. Here I'll just post meta-questions. I mean such questions has: "Why is it necessary to build on an axiomatic basis the real numbers? Why are we also presenting physics in an axiomatic way? That allows a &#46...

Exploring the Mountain: The Wave Function Exercises 01

http://physicsfromthebottomup.blogspot.com/2014/03/the-wave-function-excercises-01.html

Noli turbare circulos meos. Friday, March 28, 2014. The Wave Function Exercises 01. J 2 =1/N sum j 2N(J)= dfrac{6434}{14}=459.6}$. Calculating for each $ { Delta j}$. Delta j=j- j }$. Hence for the variance it follows. Sigma 2=1/N sum ( Delta j) 2N(j)= dfrac{260}{14}=18.6}$. Hence the standard deviation is. Displaystyle sigma = sqrt{18.6}=4.3$. Sigma 2= j 2 - j 2=459.6-441=18.6}$. And for the standard deviation it is. Displaystyle sigma = sqrt{18.6}=4.3$. Hence for the digits it is. The plot for the prob...

Noli turbare circulos meos. Thursday, February 27, 2014. 8212; 2. Initial Considerations —. Without being too far away from the truth one can say that modern Fundamental Physics rests on these three conceptions. The concept of field. The theory of relativity. The concept of field is essential to all of our future discussion hence we'll define it right away:. Field is an mathematical structure with a defined value in a given set of points. A field is said to be a scalar field when it assumes scalar values.
