First limp glimpse on logic fringe

Hello reader, and welcome to my modest blog. My diminutive home is my castle and it's both particles and waves at the same time. What a strange place that must be, having such dualistic features! But fear not, in order to see and feel that offbeat place you would have to be smaller than small, itsy-bitsy person. Basically an arch-Lilliput suffering from severe malnutrition.

Most of the blogs I have came across seem to concern about fashion and food. While I like cooking myself, it's not something I enjoy to writing about. It is more like form of creativity to me (and there is a reward at the end!). Same goes for clothing. I find fashion boring subject for a blog. Although I must admit that I wouldn't mind receiving free samples of clothes for I heard that bloggers get bribes concerning the subject of their blogs. Not much help for me there then, since on this blog I'm going to write about my experiences on quantum mechanics.

It's a dragon in case you were wondering

It gets nasty


I had studied only classical physics in university prior paying much attention to kinky quantum world. I think I found the classical physical world somewhat boring. Everything was well organised and well defined. There was usually only one good path getting from question to answer. As if the whole world was clockwork like Descartes would have fantasized it to be. I find it hard to concentrate in these kind of conditions. I like it when things get bit off and the interpretations take us to whole new bizarre world.

It was by a change that I stepped out the familiar every day world and stepped in another, more irrational one. The first book I read about quantum way of thinking was Helge Kraghs "Quantum Generations: A History of Physics in the Twentieth Century". It focused on historical aspect of quantum mechanics. If you already have basic knowledge on physics and mathematics and you aren't that interested in history, you might want to skip this book. Even though I was familiar with quantum physics before, not until while reading this book I realized how different and revolutionary quantized way of seeing nature has been compared to classical physics. I would recommend this book to anybody who wish to learn something about modern physics historical aspects. For me it was really the book that was pretty nice slippery slope to more complex books of modern physics and altogether civilizing experience.

Classical physics endured fairly long period of history as the most accurate scientific theory for movement, gravity and lots of other things too. If start of the classical mechanics is pinpointed to publishing of Isaac Newtons Principia in 1687 and was made obsolete in 1900 by Max Planck on his work on black body radiation then the era of classical mechanics lasted 213 years which is long life for a steady, all inclusive scientific theorem. Of course, such pinpointing is open to interpretation and will only lead to a wasteful debate in which everyone is a looser. In the end the start and the end of the classical mechanics cannot be placed in certain year since classical mechanics is still used widely and for good reasons too. It is versatile and it just makes more sense in the scale of everyday life. It would be as far as I know impossible to model for example a car crash scenario using Schödingers wave functions. Schödingers famous cat in a box - though experiment describes this hurdle.

They say that we need to learn how to walk before we can learn to run. Well if classical physics is walking here and quantum mechanics is running, then I would say that I learned to limp before I tried to run blindfolded. But there is definitely pleasure in trying and dying when things get proper mad.
