Benoit MandelbrotThe mathematician Benoît Mandelbrot who developed the geometrical shapes, fractal, died at the age of 85 years.

The French and American nationality, Mandelbrot, named and developed the fractal theory as a mathematical way to capture the infinite complexity of nature.

Fractals are used for measuring natural phenomena, that were regarded as non-measurable, such as clouds or coastlines. These discoveries have applications in many fields such as geology, medicine, astronomy, mechanical engineering, but also economics and anatomy.

According to his family, Benoît Mandelbrot died in Cambridge, Massachusetts from pancreatic cancer.

French President Nicolas Sarkozy in a statement paid tribute to the great mathematician, “a strong spirit, authentic, never hesitated to make innovations and to fight against established views.

Benoît Mandelbrot was born in Warsaw on November 20, 1924, in a Jewish family of Lithuanian origin. To escape the Nazi threat fled to France with his family, and then moved to the United States after the Second World War.

Beyond God and atheism: Why I am a ‘possibilian’

But good science is always open-minded, and the history of science is one of surprises and overturnings. Science is nothing but careful thinking, and careful thinking encourages an appreciation of the complexity of the world. The complexity encourages us to maintain several possibilities at once. In a single lifetime, we may have no way to remove the ambiguities from these possibilities.

Scientists isolate, hold, photograph individual Rubidium 85 atom

(PhysOrg.com) — In a major physics breakthrough, University of Otago scientists have developed a technique to consistently isolate and capture a fast-moving neutral atom – and have also seen and photographed this atom for the first time.

Random numbers created out of nothing

Now Christian Gabriel’s team at the Max Planck Institute for the Science of Light in Erlangen, Germany, has built a prototype that draws on a vacuum’s random quantum fluctuations. These impart random noise to laser beams in the device, which converts it into numbers.

Sound can leap across a vacuum after all

Now a theoretical analysis by Mika Prunnila and Johanna Meltaus, both of the VTT Technical Research Centre of Finland in Espoo, suggests that sound may be able to leap across a vacuum separating two objects made of piezoelectric crystals. These crystals generate an electric field when squeezed or stretched by sound waves or other forces, and deform in an electric field.

Study shows real partners are no match for ideal mate

Our ideal image of the perfect partner differs greatly from our real-life partner, according to new research from the University of Sheffield and the University of Montpellier in France. The research found that our actual partners are of a different height, weight and body mass index than those we would ideally choose.

Unlocking the secret of beauty: Scientists discover the complexities of attractive female bodies

Scientists in Australia and Hong Kong have conducted a comprehensive study to discover how different body measurements correspond with ratings of female attractiveness. The study, published in the Journal of Evolutionary Biology, found that across cultural divides young, tall and long armed women were considered the most attractive.

Can the weirdness of quantum mechanics make you well, or make you wealthy?

quantum mechanics

I was doing a search on twitter about quantum mechanics and in the results I saw a lot of tweets about products that use quantum mechanics to change your life! Apparently some people believe that quantum mechanics can make you wealthier and healthier.  Can someone really use a physics theory (which is very hard to understand) in order to change his life? If you really don’t have an answer on that you can start your quest for an answer by reading the following post in Cosmic Log;

How to spot quantum quackery

This is an interview with Lawrence Krauss the writer of “The Physics of Start Trek”.

People want to believe that they can easily change everything without effort, but physics is all about understanding limitations;

The quantum world does pervade everything around us, but as Richard Feynman liked to say, “Scientific creativity is imagination in a straitjacket.” Not everything is possible. That’s what makes the world so interesting.

Maybe we don’t know everything about Science and quantum mechanics, but that is also the beauty of it; we are working hard in order to understand more, and to create more.

With quantum mechanics, there’s a notion that observers affect the things that they’re observing. That’s not always true, but it’s often true. That’s one of the very strange properties of quantum mechanics. Therefore people get the notion that there’s no objective reality, and that you can literally impact on the external world just by doing things internally. That’s not the case. If you want to affect something in the external world, you have to do something to it. You can’t just hope for the best. You can’t bring good things to you by thinking about them.

Knowledge has its scope and limitations, we have to understand that;

Quantum mechanics is often quoted as the explanation for many things, because it’s so weird that people latch onto it as a hope, to explain everything that they would like to believe about the universe.

Magic is linked to the belief that everything is possible with little or no effort; that is not the case with Science

There are lots of things in quantum mechanics that sound like magic. But sounding like magic and being magic are two different things.

Is quantum mechanics a new fashion?

Often, people who are trying to sell whatever it is they’re trying to sell try to justify it on the basis of science. Everyone knows quantum mechanics is weird, so why not use that to justify it? … I don’t know how many times I’ve heard people say, “Oh, I love quantum mechanics because I’m really into meditation, or I love the spiritual benefits that it brings me.” But quantum mechanics, for better or worse, doesn’t bring any more spiritual benefits than gravity does.

Paradigms and Revolutions

” Paradigms and Revolutions” has been created to showcase the work of a Philosophy of Science course at the Rochester Institute of Technology in the Winter Quarter of 2008-2009. On the blog, students present their research on philosophical problems in the special sciences. We hope that you will find this collection of problems and resources useful!

THE MOST IMPORTANT EVENTS IN OUR AND YOUR SUPERSTRINGY UNIVERSE AS SEEN FROM A CONSERVATIVE PHYSICIST’S VIEWPOINT

On quantum resonance

Welcome to my Quantum Philosophy blog. This is a place to present and discuss my ideas and questions, perform thought experiments and share. I humbly accept that we are unable discover the true nature of our universe from the inside. Please add your questions, comments or proposals. Thanks for visiting! Max J. Pucher

physics musings

“…Once upon a time, i completed a thesis on gravitational wave detectors, and got a Ph.D. that culminated more than twelve years of my life devoted to physics. Normally, that would have been just the beginning of a researcher’s career, but sometimes life intervenes and, as was my case, the doctorate marks instead what seems its end. I shifted gears and began a professional career as a programmer, not an unheard of story. During more than eight years, i’ve had lots of fun discovering a new world, full of interesting people, with its own myths, heroes and battles. I’ve tried hard to learn and even give something back, and, until a few months ago i was pretty happy with the idea of going on that way for the foreseeable future…”

Partially Examined Life

The podcasters were all graduate students in philosophy at the University of Texas at Austin back in the Clinton years. They all left the program at some point before getting their doctorates and have consequently since had time to get outside that whole weird world of academia and reflect on it and the various philosophical topics with a different, and probably much more lazy, perspective.

Legal Theory

Professor Lawrence Solum is the John E. Cribbet Professor of Law and Philosophy and co-director of the University of Illinois’s Institute for Law and Philosophy. Professor Solum is an internationally recognized expert on legal theory, who works on the philosophy of law, civil procedure, constitutional Ttheory, Internet governance, and a variety of other topics. He is the author of Legal Theory Blog – widely recognized as one of the most influential sources of commentary about the world of legal ideas. Solum’s current research focuses on three areas: (1) procedural fairness, (2) the relationship between the philosophy of language and constitutional theory, and (3) the intersection between virtue ethics and the philosophy of law.

Serkan Zorba’s blog

Dr. Zorba attended Hacettepe University from 1992 to 1997, and graduated with a Bachelor of Science degree in engineering physics as valedictorian in theDepartment of Engineering Physics, and as salutatorian in the Faculty of Engineering. He then came to the University of Rochester in the Fall of 1997 with full tuition and scholarship and began his graduate studies in the Department of Physics and Astronomy. He received a Master of Arts degree in physics in 1999, and then joined Prof. Yongli Gao’s group to carry out research on the morphological and electrical properties of organic semiconductors. He completed his doctorate degree in July 2004. He spent one year as a visiting professor beginning in Sept. 2004, and has become a tenure-track assistant professor of physics in Sept. 2005 in theDepartment of Physics and Astronomy at Whittier College .

think deviant – philosophy of science

“In theory, there’s no difference between theory and practice. But in practice there is.” -Yogi Berra


the observer effect

I love science. In particular, I love quantum physics. The work of Bell, Bohr, Schrodinger, Heisenberg, Dirac, Bohm, DeBroglie, Feynman, Wheeler, DeWitt, Von Neumann, Wigner, Penrose, Everett (and others) excites and inspires me. Their experiments raise an open question regarding the nature of existence; their findings allude to the role of consciousness in the construct of reality. Quantum theory proves that it is the act of observation itself that causes a wave function to collapse out of either/or uncertainty into what we experience as a particular reality… My “reality.” Your “reality.” Everybody’s “reality.”

On Philosophy

This blog exists in order for me to develop my thoughts on various philosophical problems that interest me. It is public because making it public motivates me to not slack off (which only works some of the time). And it is nice to be able to point people at a post that reflects something we had been discussing previously. Now this is not to say that I don’t care about you dear reader. I do, and I will do my best to be clear and to answer any questions you have, but there are limits to how much I care. Specifically I am not trying to change your mind or convince you of anything; it doesn’t matter to me what you think.
