Monitoring earthquakes with satellites  

Comment this

Italian Scientists from INGV (Istituto Nazionale di Geofisica e Vulcanologia)  use the latest images from the European Space Agency to map recent fault displacement.

a simple explanation of the concept here:

“While the fault and the earthquake epicenter are often deep below the earth’s surface, the ground above the fault moves a little too. This movement is very slight, but it is possible to measure it with high precision GPS instruments, or with satellites.”

the data are freely available at ESA:

“ESA makes freely available to the scientific community a dataset of SAR products (Envisat and ERS) corresponding to the earthquake of L’Aquila (Italy) which took place on 6 April 2009. The ESA package also includes data from Third Party missions, in particular Japanese ALOS data.”"

a Solar Cooker to save the world?  

Comment this

Jon Bohmer [photo] has invented a cheap, solar-powered cardboard cooker for rural Africa called the Kyoto Box. The invention seems to be very useful and promising.

The Kyoto Box, a $6 solar cooker made from cardboard, has won the Financial Times-sponsored Climate Change Challenge.

Black paint on the inner box, and silver foil on the outer one, help concentrate the heat. The trapped rays make the inside hot enough to cook casseroles, bake bread and boil water [CNN]. Covering the cooking pot with a transparent cover retains heat and water [BBC]

Abstract:We identify a process of global pattern formation that causes regions to differentiate by culture. Violence arises at boundaries between regions that are not sufficiently well defined. We model cultural differentiation as a separation of groups whose membersprefer similar neighbors, with a characteristic group size at which violence occurs. Application of this model of the former Yugoslavia and to India accurately predicts the locations of reported conflict to the area. This model also points to imposed mixing or boundary clarification as mechanisms for promoting peace.

I personally believe, socio historical patterns of human particles are statistically predictable.

I think Science has to focus more on this promising area which could  benefit mankind quite a lot.

Happy New Year, China!  

Comment this

Today I woke up noticing my Chinese neighbours being quite excited. They were setting the laptop in the kitchen and trying to watch the main chinese tv channel (CCTV) through the internet.

What’s going on here? - they look at me quite surprised -come on you don’t know? today is new year’s eve in China! For all Chinese people around the world is a very important day!

[from Wikipedia] Chinese New Year or Spring Festival is one of the most important traditional Chinese holidays. It is sometimes called the Lunar New Year, especially by people outside China. The festival traditionally begins on the first day of the first lunar month (Chinese: 正月; pinyin: zhÄ“ng yuè) in the Chinese calendar and ends on the 15th; this day is called Lantern Festival. Chinese New Year’s Eve is known as ChúxÄ«. It literally means “Year-pass Eve”.

Wow! nice!!!!!! You can also have a look at this video:

CCTV1 was broadcasting a huge special about this, but, surprisingly they did not show so much about colorful celebrations . They focused on the president Hu Jintao visiting common people, poor people, people who have to work during this holiday, etc. They then showed famous places around the world where people were celebrating China new year’s eve (not only Chinese ones, like in Harvard and NY). The atmosphere of spreading happiness seemed to me quite genuine. Maybe you can disagree on this point and call it propaganda. I don’t think so. I was feeling a kind of true human contact between the highest chinese politic figure and the common people of the “People’s Republic of China“.  I was impressed.

And you know, the Chinese wave is huge. When it resonates worldwide with such a positive energy (as it was at the Olympic Games last year) is really nice.  I think, I’ ve got a better insights into their culture, today. Of course I remain aware of the dark side of the moon.

Happy New Year, China!

W. Heisenberg, “Physics and philosophy”- Review  

Comments (1)

Hello Physics&Philosophy Freaks! this is the first post of my old friend Max, bio-engineer with a passion for Physics and “itself” an advanced positronic brain. But he missed the proper name of HeiseNberg, probably due to the U.P. … [Ok ok, I've corrected the spelling, NdMax]

..btw, if you don’t know Heisenberg&Co, either you commit directly suicide or you just do it after watching “Electrons Are Weird ..[ anyway this nice vid from BBC is also recommended to all of you]

c h e .. r s! :-)

***********************************************************************

W. Heisenberg, “Physics and philosophy” (Der Teil und das Ganze,1954)

The author of this book doesn’t even need a presentation. The style is definitely very smooth and accessible, and fancy maths is removed altogether.

The purpose of the whole essay (written in 1954) was to give a summary about how the evolution of physics, throughout the centuries, was able to revolutionise the very idea of reality, and how the early cartesian “Weltanschaung” heavily influenced the successive development of natural sciences and of the scientific method itself.

The first chapters are a fast-paced summary of 2500 years of epistemology (philosophy of knowledge), from the ancient Greek to the present (well, at least the present as it was in the ’50s).

In the following, Heisenberg takes the reader by the hand and introduces him/her to the most counter-intuitive aspects of quantum physics. He then explains how and why such results required, in order to be interpreted, a radical philosophical revolution within the scientific community, a revolution that, at the time when the book was written, was still at the center of white-hot debate.

Einstein is regarded as the man who first introduced a radical Ockham’s razor-like approach to physics, that first produced the Special Relativity by removing the (physically unnecessary) dogmatic belief in the absoluteness of time and space.
However, according to Heisenberg (and we educated 21st-century people can respectfully agree), Einstein himself was not able to take his approach to the extreme and shocking consequence, namely the necessity of removing the principle of deterministic causality in order to interpret some of the observed physical phenomena (an operation that led to the birth of quantum physics).
All his life he remained skeptical about the metaphysical implications of the new theory.

And here comes the most interesting thesis proposed by the book:
Heisemberg tracks the difficulty of this paradigm shift, back to the “original sin” committed by Cartesius, when he divided reality into “res cogitans” (human mind) and “res extensa” (all the rest), and assuming that the laws of physics would apply only to the second (at the time the distinction appeared necessary in order to cope with the problem of free will).
This -in itself, illegitimate- assumption would have then propagated through the centuries, producing a widely accepted view of the physical world that was lacking a solid justification both on physical and phylosophical ground.
Of great interest is also Heisenberg’s insight in the foundations of the experimental method, where a suggestive (and quantistically corrected) version of Immanuel Kant’s “a priori” is proposed.

A highly recommended reading.

le lumache - (il primo post di Mik!)  

Comments (1)

Signore & Signori, Homini e Donne sapiens sapiens sapiens,  Amanti, A-Mantidi e Procarioti,

ecco a voi il Mik, talento introspettiv-nucleare-darwiniano, affabile et ironico, mai casualmente maldestro, e da oggi esimio collaboratore di Tecnopolis.. basta non indulgiamo oltre.. viel Spass! AZ

******************************************************************************************************************

È ora di basta con queste informazioni inutili sugli elicotteri mai costruiti [o sui video fantaidealisti dello Ziller - NdAZ]. Cominciamo uno o piú discorsi seri.

Per esempio: la vita, la morte, le tasse, la fi… ehm, il sesso. Vi aspettavate anche l’amore? Ebbene vi svelerò un segreto. Ma non ora.

Ah, ho dimenticato la sciènza (come lo direbbe Crozza che imita Zichichi) nell’elenco suscrittomenzionato.

Pensavo alle lumache. Sapete che si mangiano anche, no? sono un piatto prelibato, le ho mangiate alcuni giorni fa. Funziona così:si raccolgono da terra o da ovunque si fossero arrampicate e le si chiude in una gabbia a purgare. Il che significa che devono espellere/metabolizzare il più possibile prima di essere cucinate e mangiate senza doversi sorbire anche tutte le erbette che hanno mangiato loro. Poi le si mettono in acqua, sale e aceto e si scalda fino a bollore. Loro, ad un certo punto di una di queste fasi (e meno male aggiungerei io coi miei buoni sentimenti), muoiono.

Ho ripensato alla morte. Capita spesso, in fondo è il nostro fine ultimo. Si nasce, si fa un po’ di rumore e balletti per far finta di lasciare un bel segno, divertirsi, fare un bel “viaggio”, tramandare ad altri la propria esperienza e i propri geni (se va bene), parvenze di immortalità, e poi, inesorabilmente si crepa. Mai provato quel senso di angoscia che insomma, prima ci sei e poi tutti i tuoi pensieri, emozioni, corpo, non ci sono più. Bella inculata, eh?

La differenza con le lumache è solo che noi lo sappiamo, loro no. Ma credo che facciamo di tutto per NON pensarci. Intendo non pensarci veramente. Domani (tra poche ore) visiterò Monaco, poi scriverò delle belle mail, più in là canterò sotto la doccia e nel coro, forse copulerò e trasmetterò un po’ di Mik in futuro. E poi un bel giorno, dopo aver letto tanti libri e soddisfatto (spero almeno un po’) del mio viaggio nel mondo, morirò.

Non troppo diversamente dalle nostre amiche lumache, dalle quali non siamo poi così diversi in fondo.

Buon appetito agli dèi.

I cannot resist to post this beautiful video on Tecnopolis. It merges one of the most beautiful song of the 80s with one of the most beautiful film ever. Beauty, like reality, is multidimensional, but human beings usually focus on just one dimension. Try to catch new dimensions of beauty and your joy will grow exponentially..

enjoy! - video credits: Yorgle, a YT video maker, also engineer :-)

 

Video - Peter Schilling - “Major Tom” (using “2001″ footage)

 

[the German version - actually the original one - is a kind of fourier transformation of the previous one. Beauty in the discretized frequency space..] 

Video - german version “Völlig Losgelöst” 

 

PS: herewith we start the category “Kubrick & Co”, one of the new things of Tecnopolis 2009! Others will come.. [I am in touch with some intelligence lifeforms around there, they promised me to cooperate - for a better Galaxy, of course..]
