Few Photos 4 - for Dog Lovers

Here are few photos of our friends’ dog we (me and my wife ) took during a barbeque they threw in June 2007.

He sure loves all attention he can get :

Tired after all the running:

But always has energy to play more:

Hungry?…

Few Photos 3 (and Panorama)

As a nice memory of summer, here are 3 of my games with macro photography:

And as a “present”, here’s an almost-180-degree panorama of what a dramatic presentation sky can make (shot on 17. June 2007):

Few Photos 2

Here are few more photos I took.

First, another of my “tracking practices” - pigeon in flight:

Next, two photos using sun - one is simple “summer idyl on the grass” and one abstract (window reflections, with blinds down):

And last for today, summer sunset in Belgrade:

Photoshop Quick Mask Tutorial

“Quick Mask” is an extremely powerful, yet often neglected and forgotten, feature of Photoshop. It is a very simple and fast way to create complex selections.

Thanks a lot to Symmetry factor for posting this!

Wonderful parody of the way HEP papers are written, by Warren Siegel, author of amazing book Fields - free comprehensive textbook on quantum and classical field theory.

I love especially the sentence “We begin by avoiding a discussion of the following relevant topics: …”.

You can find more physics parodies on Warren Siegel’s pages.

Btw, am I the only one who finds arXiv’s search to be really crappy?

Few Photos

First of all, photo of my favourite cat - she’s a real bookworm cat.
[Info: I have no idea to whom this cat belongs, if to anyone at all, I just often see her sleeping in a window of one bookshop, just like in the picture]

The Hitch Hiker’s Guide to the Galaxy - 3 PDF Books

Few years ago I made the following 3 PDF’s of The Hitch Hiker’s Guide to the Galaxy 5-books series, for my old web site.

On the Nature of Time

The age old question is haunting me lately quite a bit, so I thought maybe I’m not alone. Here are few points on the nature of time I have to say. Well, more than few points it’s few questions.

All photos were taken in Belgrade, Serbia, in April 2007.

100th Anniversary of Landau’s Birth

Thanks to “Symmetry factor” blog for pointing this out.

Lev Davidovich Landau, a brilliant theoretical physicist and a founder of a whole school of thought in theoretical physics, was born exactly one hundred years ago, on 22 January 1908. His work was amazingly broad, from condensed matter physics to quantum field theory. He was awarded the Nobel Prize in 1962 for his work on superfluidity of liquid helium. He is one of the few people in the world whose student - Alexei A. Abrikosov - also got a Nobel Prize.

He is also, together with E. M. Lifshitz, author of a renowned 10 volume course in theoretical physics, covering incredibly wide range: Mechanics, The Classical Theory Of Fields, Non-Relativistic Theory of Quantum Mechanics, Quantum Electrodynamics, Statistical Physics (2 volumes), Fluid Mechanics, Theory Of Elasticity, Electrodynamics Of Continuous Media, and Physical Kinetics!

Though in todays standards bit harder to read (in my opinion), all 10 volumes are an incredible source of information, and always very handy as a reference handbook, or study book.

For some time now, I’m a proud owner of all 10 volumes, and since some time ago, also of the electronic versions of all 10 books. If anyone’s interested, I’d be happy to share these. Just let me know = leave a comment.

Last word - my favourite part of the mentioned course is when Landau says “as reader can easily verify himself”; I once tried it, took me some 5 pages of computations, but the result was right.
