Before we jump into premature conclusion with easy answers as 'nothing at all' or 'at least they are both orbiting the Sun' perhaps we could do some quick research for just in case... With equatorial radius of Jupiter almost thirty times bigger than the same property on Mercury, obvious composition difference between one gas giant and small rocky planet and all the other major difference in mass, density, temperature, orbital inclination, orbit period and with almost everything we could compare the two, it is very hard to find the slightest similarity.

Rarely I've got a chance and real opportunity to revive an old article from the past and to update it to fit better in the present day. Actually, the quantum weirdness is still where it was four years ago - science is not something that changes over night especially with quantum mechanics, so I am not going to update the post with any new physics or breakthroughs. Instead, what 's new and what pushed me to repost today is one extraordinary novel in the field. The book that kept me from sleeping last weekend was "Quantum Space" by Douglas Phillips and in short it is by far, one of the best titles I read this year. It is one of those true sci-fi stories that follows the real science and in this case the weirdness of the quantum world I wrote about in this post and I would add one of those articles I enjoyed the most writing in the history of the blog. But, before couple of my glimpses to the book itself, followed by my warm recommendation and especially if you want to r

It happened long ago, in the dark ages of CRT monitors, when I first received a short forum message with :-) at the end. I stared at the message for a long minute(s) before giving up of decoding its meaning. It came from a well respected friend of mine so I responded with short reply: "What!?" "You have to turn your screen 90 degrees clockwise." Answer came promptly. My CRT was large and heavy and it looked way too dangerous to tilt it that way so after little brainstorming the problem, I concluded there's a better way of achieving the same goal. I tilted my head 90 degrees anticlockwise. "Aaaaaah!!!" I said promptly and after realising the picture, big smile on my face slowly morphed into loud laughter. So I typed back: "Wow!" I didn't have to wait long for the next message: "LOL!" "What!?" - I quickly copy/pasted my earlier message but realised I was too not informed about new internet fashion so I

First names. They are of the most importance. Not the middle ones. Not even the last ones, even though with some people family name comes with higher significance, especially if they are part of some important heritage or well-known royalty. Even so, the first names comes, ... well, first. And not by accident. This is how you are remembered for your entire life. This is the word you turn to when you hear somebody is calling around the corner. This is you. With me is the same and while ago I decided to start a thread with first names in titles. First names that are telling connected tales, historically or with any other linked stories. So far there are two in the row: Jules, Isaac, Arthur and Carl and Giordano, Isaac, Albert and Stephen . Behind those names are, according to me, people who gave the biggest push in the worldwide literature of science fiction and science itself. These are people who fit my own interests and fascination and they will be remembered for eternity for their w

Moon travels around the Earth in elliptical orbit and logically there are two points in its path where it is closest and farthest from us. Today it was in "perigee-syzygy" of the Earth-Moon-Sun system or simply called "supermoon". Coincidentally, it happens that today it has the power to fully block the sunlight in northern Europe and made the biggest shadow one can do on Earth. In Serbia it only made partial eclipse covering somewhat less than 50% of the Solar disk. These are 12 photos I took in intervals of approximately 10 minutes from eclipse start at 9:40 until it went away around 11:58. The biggest shade was at 10:48. We were pretty lucky today since the nature gave us clear sky with just one stubborn cloud that covered the Sun-Moon kiss around 11AM. Above image is the composition of those 12 photos which I took through our Sky-Watcher telescope with solar filter. I still don't have proper camera or adapter for taking astronomical photos so I used

Did you know that if you were standing on the near side of the Moon, and for your mass of 80kg and weight of 785N on Earth, due to Moon's lower gravity, you would not feel being heavier than 13kg (130N)? You knew? Ok, did you know that Earth's and Moon's gravities combined gave you different weight on near and far side of the Moon? Slightly yes, but true. Earth and Moon are relatively small celestial bodies but this difference goes even higher if you move from the Moon to the Io or Europe for example as they are also tidally locked by Jupiter just like our Moon is locked by Earth. This would most definitely not help mountains on Avatar's Pandora to float but still, within right conditions and with presence of large mass(es) nearby, considering appropriate composition of the ground I am sure there are solar systems out there with strange conditions to live with, to say the least. "If I have seen further it is by standing on the shoulders of giants” - Isaac Ne

Do you have that strange feeling when you are about to visit new city abroad and little afraid of what you would stumble to when it come to simple things? Like how to use metro line or how to buy a bus ticket or how to identify your next destination? Or how to book your flight back to your home? Or how to handle a simple dilemma of should you exchange the money to the local currency or is it wise to put your card in every ATM or any other 'slot' machine on your way? Hello™ at Microsoft Campus Days, 2014 Ericsson, a Swedish multinational provider of communications technology and services, has the answer for you. And me too. Last week, I took my entire family to the trip to Copenhagen for both, business and pleasure hours in the Danish capital. During my previous visits I didn't have much time for tourism and any off work activity for that matter. So I took a little research this time and Ericsson's " Networked Society City Index " helped a lot. Within t

Do you know what is one significant difference between Uranus and all the other planets in Solar system? Unlike the other seven planets who, more or less, rotate in "normal" up-down position (or down-up in case of Venus), Uranus is quite abnormal. It's north-south pole rotational axis lies almost in ecliptic because it is tilted by 97.8 degrees and rotates in almost vertical direction toward the orbiting plane. In simple words, Uranus is one giant rolling ball where if you are located on its pole, you would be experiencing only one day and one night during 84 years long orbit while if you are settled near the equator, thanks to ultra-fast rotation time (for a giant planet) of 17 hours you would be experiencing fast switching between day and night and during both solstices the Sun would always be on the horizon. Thanks to this strange position of Uranus axis (probably due to some cosmic collision happened in early Solar system), the weather and climate on Uranus are always

Original post date: May 2013, Update: September 2017 "When I think about everything we've been through together, maybe it's not the destination that matters, maybe it's the journey." This one-liner belongs to Harry Kim, a character from the Star Trek Voyager show - probably the episode when they all realized the ultimate truth about how far Earth is from their location and that even the lifetime might be too short to reach it back. It was one great show I swallowed in just couple of weeks back then in the beginning of 21st century. I remember I was watching up to 6 episodes every night and now looking to it from today's perspective perhaps the most memorable line I still remember is this one about famous journey-destination quote. So, what is your ultimate answer? Is it Journey or Destination? For me there is no doubt, it is always the journey. Even for travels as small as 50km we do to escape city on weekends and go to the mountain village I mention

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.
