In seven brief little lessons the Italian theoretical physicist Carlo Rovelli gives the reader an absolutely astounding introduction to modern physics. From quantum theory, elementary particles, to black holes, time and space, and gravity. It is all explained in an awe-inspiring way, and it is all done in mere 79 pages.
I had decided to read more about the conflict(s) in the Middle East and put the science books away for a while. But then as many times before I happened to pass the book store at Oslo Airport Gardemoen. I am seldom able to walk away without buying books there. And this time I picked up Seven brief lessons on physics. It looked interesting not to mention very short. So short that I was sure my books about the Middle East wouldn´t be offended by me being unfaithful to them.
This is as already mentioned a short book, and each chapter is only about ten pages. The language is beautiful and you feel a lot smarter as you read your way through. I am sure that the author Carlo Rovelli must know the works of Carl Sagan very well. They have a very similar poetic way with words. These lessons are expanded from articles the author wrote for the italian newspaper Il Sole 24 Ore. The book has sold more than 50 shades of grey in Italy. I am not sure if that says more about the Italians interest in science or sex, but nevertheless it is worth noticing.
“For now this is what we know of matter:
A handful of types of elementary particles, which vibrate and fluctuate constantly between existence and non-existence and swarm in space even when it seems that there is nothing there; combine together like the letters of a cosmic alphabet to tell the immense history of galaxies, of the innumerable stars, of sunlight, of mountains, woods and fields of grain, of the smiling faces of the young at parties, and of the night sky studded with stars.”
All chapters are interesting in their own way, but I especially like chapter five. It deals with the paradox and contradiction between the quantum mechanics and general relativity. General relativity deal with cosmology, astrophysics, gravitational fields, and black holes etc. Basically the physics of the very large. Quantum mechanics deal with the elementary particles, atomic physics, nuclear physics and condensed matter etc. The physics of the very small. The two areas of physics have both been extensively confirmed by experiment. But at the same time they contradict each other. And it is about here my head starts to hurt. That is actually wrong of me to say. Because my head starts to hurt all the way through the book.
“The ´present´does not exist in an objective sense any more than ´here´exists objectively, but the microscopic interactions within the world prompt the emergence of temporal phenomena within a system (for instance ourselves) which only interacts through the medium of a myriad of variables.”
In the last chapter we humans are the central topic. What are we? is everything particles and elementary forces and therefore deterministic? Rovelli tries to show us how the scientific method is like an antilope hunt where the hunters follow the tracks and tries to figure out where the animal went. The hunters have to change directions with new information if they want to eat. I quite like the comparison. He then briefly discusses whether we have free will or not, our conscience, the consequences of what we are doing to the planet. Needless to say he is not the most positive of gentlemen.
“I believe that our species will not last long…We belong to a short-lived genus of species. All of our cousins are already extinct. What´s more, we do damage. The brutal climate and environmental changes which we have triggered are unlikely to spare us… Especially since public and political opinion prefers to ignore the dangers which we are running, hiding our heads in the sand.”
This is an amazing book that will make you want to read it again and again. Because it contains so many mind blowing things about the world we live in and about ourselves. I think everyone should read it. It will definitely improve the readers fascination for natural science. Which I think is the main goal of this book. If you want to actually learn the intricate details of the topics mentioned in this book you should´ve read something else. But as an appetizer it works great.
“Here, on the edge of what we know, in contact with the ocean of the unknown, shines the mystery and the beauty of the world. And it’s breathtaking.”

Israel er et sentrum for utvikling av high-tech, det er et av verdens mest militariserte samfunn samt også det i-landet med størst andel fattige. I år er det også 50 år siden Israel begynte sin okkupasjon av Vestbredden, Gaza og Golanhøydene. Det var på tide at jeg lærte mer om historien om Israel og Palestina.
I boka er det også lagt med et kart over Vestbredden som viser omtrentlig hvem som skal ha kontroll over hvilke områder i henhold til Osloavtalen. Som dere ser selv er det litt av et lappeteppe. Noen områder skulle være under israelsk kontroll, andre under palestinsk kontroll, og noen skulle være under delt kontroll. Nå er det lite igjen av
The seaman Marlow travels up the Congo river as the captain of a steamer to find the mysterious Mr. Kurtz, a renowned ivory trader. As he travels up the river he descends into the horrible consequences of the colonial scramble for Africa. As well as a description how brutal and vicious europeans plundered the Congo, it is also a story about morality and the thin line between civilization and savagery.
This book is an awesome combination of 1980s nostalgia, video game trivia, and a quest from a roleplaying game. All set in a dystopian future where almost everybody has logged on to OASIS. So if you grew up in the 80s and 90s and played more than a few video games this is definitely a book you should read.
Dersom du leter etter en kort og grei introduksjon i livet til Winston Churchill er dette boken for deg. Her får du en allsidig og oversiktlig fortelling om en av de viktigste menneskene i det 20. århundre.
Boka er del i to deler hvorav den første delen handler om interne forhold i Syria. Vi får en gjennomgang av geografien, folkegrupper, og historien til landet. Folkeslag som drusere, jesidier, arabere, tyrkere, kurdere, kristne, shiamuslimer, sunnimuslimer og alawitter blir introdusert. Vi får også en beskrivelse av hvordan den arabiske våren også kom til Syria i 2011. Hensikten med boken er å forklare hvordan lokale demonstrasjoner utviklet seg til å bli en regional konflikt som truer hele Midt-Østen. Og ikke minst hvordan det som styrtet flere andre land nettopp ikke var nok til å endre styresettet i Syria. Assad har et enormt stort militære og han har svært god kontroll på sine militærstyrker. På et tidspunkt var det registrert flere tusen forskjellige fraksjoner av opprørere, men uheldigvis klarte ikke de kommunisere med hverandre. eller en gang bli enig om hva de egentlig ønsket. Det sloss også flere tusen forskjellige fremmedkrigere fra over 100 forskjellige land i Syria. På alle sider av konflikten.

This is the personal journal of Charles Darwins from his five years onboard the surveying ship HMS Beagle. This trip ultimately led him to formulate the theory of evolution. Which in turn was published many years later in 1859 in the well known book Origin of species
