"At some point, the gluons will no longer be able to hold the quarks together, and the hadrons will decay. Which will mean the end of matter in this universe." - Albert Einstein  1 As it seems, in our universe, nothing is made to last. Eventually, everything gets old and dies or changes or decays into something else, and I am not referring to the life forms only but all matter in the cosmos. For all we know, this might not be true within our own macroworld alone, but also deep below, the same goes for particles in the quantum realm as well. The fact is that everything in the universe has a tendency to achieve the lowest energy state and to finally rest within a stable system, even if that means going through various changes or decays. In the quantum world, this could be true for the Higgs field as well. According to Hawking, if it becomes meta-stable, the vacuum decay bubble will emerge and consume everything in order to eventually reach the lowest energy state possible. F...

Not so long ago I mentioned great city of Alexandria in post Constantine & Naissus when I described the horrible misfortune and death of Hypatia, one of the greatest philosopher and astronomer of 4th century AD, who lived at the very end of classical Greek era of prosperity. Within the same city walls, couple of centuries before, one of the equally greatest and famous scientists of all times, Claudius Ptolemy was living, exploring, teaching and dedicating his life in various disciplines including astronomy and, of course, unavoidable astrology which was considered to be "connected science" for centuries, especially in the old ages. Rachel Weisz as Hypatia of Alexandria in Agora (2009) Among other things, Ptolemy will be remembered as the one of first scholars who described and identified 48 constellations of clear and unpolluted nightly skies above Alexandria so many centuries ago. One of the biggest constellations in his list was the great constellation of Gem...

If you were reading my blog in the past you probably noticed that on several occasions I mentioned inner fight in all human beings between rational and emotional mind. More or less we all 'suffer' from this conflict and this post is, again, going to be tailed by it. Okay, now, you read the title and already hinted about the content, so let's get to the story. But before diving into topic, let me start with a revelation and for the first time since I started this blog I think this very title finally would allow me to go more personal than usual. Actually, I decided to reveal everything about me in this post and finally you are about to learn who I am to the bone. Are you ready to read further? Okay, I am ready. Here you go ... I am ... Wait ... I hate these second thoughts ... Darn it, I can't take it back now, can I ... Okay, here it is ... ... I am Scorpio. There you go. I said it. Phew. What a relief. Now you know everything about me. Who I am, why ...

I remember every little detail from that weekend trip. From the very first moment when we stepped into the bus that took us to the mountain base, throughout the rest of the first day when we climbed down into small cave with narrow hallways toward the small chamber at it's end. I vividly remember glorious, endless and hard-to-find second cave we stepped in the very next day, followed by overwhelming feeling and little fear when we passed through cave chambers, cutting the darkness with handy tools and small flashlights. I will always hate myself, for not having a camera to capture surrounding scenery when we traveled by train later that afternoon, who looked like it came right out of 19th century with wooden benches rolling the railways slower than Usain Bolt. All those rock formations and abandoned train stations were slowly losing their battles with nature and were looking exactly like a background from Sergio Leone's spaghetti western movies.

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 ...
