You probably heard that matter is pretty much an empty space. It's true. Everything is made of tiny particles with nucleus in their centers and cloud of electrons orbiting around. If we take Hydrogen (H) for example - the smallest atom with just one proton in nucleus orbiting by just one electron and if we scale the proton to be the basketball size, the orbit of the electron in diameter would be something about 15km. Both, nucleus and electrons are electromagnetically charged, keeping everything in stable equilibrium and also inside nucleus two more fundamental forces - strong and week nuclear interactions are keeping all the matter and energy in line. However, the smallest atom in the Universe is not the smallest, standalone system we know of. According to standard model, all atoms and complex molecules found in nature or artificially produced are made of fundamental particles. Something we cannot cut into smaller pieces. Electron is one of them. But there are more. So far, as far

Lately I was watching current stream of war related news and Syrian migrant crisis and I thought of what would I say on the blog about actual, continuous and devastating warfare in Europe, Africa and Middle East and stupidity of literally inexplicable background of who is fighting whom in all those conflicts and what cause would justify the aftermaths in form of devastated cities and long refugee-columns... Or even what words should I use to describe foolishness of the new cold war between nuclear powered "super countries" and what that will mean for our children and theirs in the future... Then I realized that reacting to meaningless affairs and worldwide political absurdity in a world so divided by racial, structural, governmental and religious diversity is also meaningless. I also realized that I said enough in the past. There is nothing new to be added or said. There will always be people who will think that rifle is not a rifle if it never fires a bullet. And to use a

In the last post of the Beth's Q&A we tried to understand four basic forces and their corresponding particle carriers or bosons. With almost certain discovery of the Higgs boson physicist completed the search for this last mystery of the standard model and we now know how larger particles get their mass and how interact with each other. Now is the time to bring this story up one level and write about chemical elements representing basic 'lego' blocks of almost everything in the universe we currently comprehend. Hmm, everything but mysterious dark matter that we still don't have a clue what it's made of. Every now and again in media (mostly internet) we can read about how we all are made out of stars and other violent events in the universe dating back in time even so far in the past to the Big Bang itself. Following some of this articles Beth posted another idea for the thread and I am paraphrasing her thoughts: "I keep reading we are made from the

Starting with this post I would like to introduce something new to the blog. Something different and yet written in a similar fashion compared to my previous stories. This would be a new thread dedicated to science only with my own narration, style and write up. When I started with the blog year ago all I wanted is to have a place where I could be able to write my public thoughts, something that could give random reader a good description of me and my view to the world and beyond. That goes to both random readers, either one living in present day or the one reading this from some different point in future time. But now with this post I am trying to expand the blog a little bit further. I am still doing it off work and in my spare time but nevertheless it is always fun and inspirational for me. CMS Particle Detector The idea for the new thread I got after my post about human relations, genographic projects and conversation with my dear Facebook friend Beth Perry Steger. Genealo
