Just Think- Sam Harris part 1 of 2


From the Free Press:

Sam Harris's first book, The End of Faith, ignited a worldwide debate about the From the Free Press:

Sam Harris's first book, The End of Faith, ignited a worldwide debate about the validity of religion. In the aftermath, Harris discovered that most people—from religious fundamentalists to non-believing scientists—agree on one point: Science has nothing to say on the subject of human values. Indeed, our failure to address questions of meaning and morality through science has now become the most common justification for religious faith. It is also the primary reason why so many secularists and religious moderates feel obligated to "respect" the hardened superstitions of their more devout neighbors. 

In this explosive new book, Sam Harris tears down the wall between scientific facts and human values, arguing that most people are simply mistaken about the relationship between morality and the rest of human knowledge. Harris urges us to think about morality in terms of human and animal well-being, viewing the experiences of conscious creatures as peaks and valleys on a "moral landscape." Because there are definite facts to be known about where we fall on this landscape, Harris foresees a time when science will no longer limit itself to merely describing what people do in the name of "morality"; in principle, science should be able to tell us what we ought to do to live the best lives possible.

Bringing a fresh perspective to age-old questions of right and wrong, and good and evil, Harris demonstrates that we already know enough about the human brain and its relationship to events in the world to say that there are right and wrong answers to the most pressing questions of human life. Because such answers exist, moral relativism is simply false—and comes at increasing cost to humanity. And the intrusions of religion into the sphere of human values can be finally repelled: for just as there is no such thing as Christian physics or Muslim algebra, there can be no Christian or Muslim morality.

Using his expertise in philosophy and neuroscience, along with his experience on the front lines of our "culture wars," Harris delivers a game-changing book about the future of science and about the real basis of human cooperation.

Just Think- Sam Harris part 2 of 2


Beautifully written as they were (the elegance of his prose is a distilled blend of honesty and clarity) there was little in Sam Harris's previous books that couldn't have been written by any of his fellow 'horsemen' of the 'new atheism'. This book is different, though every bit as readable as the other two. I was one of those who had unthinkingly bought into the hectoring myth that science can say nothing about morals. To my surprise, The Moral Landscape has changed all that for me. It should change it for philosophers too. Philosophers of mind have already discovered that they can't duck the study of neuroscience, and the best of them have raised their game as a result. Sam Harris shows that the same should be true of moral philosophers, and it will turn their world exhilaratingly upside down. As for religion, and the preposterous idea that we need God to be good, nobody wields a sharper bayonet than Sam Harris.

— Richard Dawkins, author of The Selfish Gene, The God Delusion, and The Greatest Show On Earth

First we are told that we are lumbering robots with selfish genes at the helm. And now we are told that biology determines our values, not only what is good for us, but what ought to be good for us. Isn't there anything sacred?! No, and thank goodness. A hallelujah to Sam Harris for boldly going where few have dared go. The Moral Landscape is both a celebration of why clarity of reason is our most glorious weapon, and why even age old debates that have gone into hibernation ought to be awakened and challenged.

— Marc Hauser, Harvard College Professor, author of Moral Minds.

Reading Sam Harris is like drinking water from a cool stream on a hot day. He has the rare ability to frame arguments that are not only stimulating, they are downright nourishing, even if you don't always agree with him! In this new book he argues from a philosophical and a neurobiological perspective that science can and should determine morality. His discussions will provoke secular liberals and religious conservatives alike, who jointly argue from different perspectives that there always will be an unbridgeable chasm between merely knowing what is and discerning what should be. As was the case with Harris' previous books, readers are bound to come away with previously firm convictions about the world challenged, and a vital new awareness about the nature and value of science and reason in our lives.

TEDxObserver - Rick Falkvinge - The Pirate Party - the politics of protest

In 2006, Rick Falkvinge, a Swedish software entrepreneur, founded a new political party 

centred around the subjects of file sharing, copyright and patents. He called it the Pirate 

Party and it rose to prominence after a government crackdown on the file-sharing site, 

the Pirate Bay. Since then, the Pirate Party has swept Europe and beyond to become an 

international political movement, active in 40 different countries with representation in 

the European parliament.

In Sweden, it's the largest party for voters under the age of 30 with 25% of the vote, and 

in September 2011, the German Pirate Party won an unprecedented 8.9 per cent of the 

vote and now has several members in the Berlin state parliament. Focused on the subjects 

of government transparency, internet privacy and copyright law, the Pirate Party hosts 

Wikileaks on its servers and uses new technology to leverage political power in new and 

interesting ways. In 2011, Foreign Policy magazine called Falkvinge one of the top 100

 global thinkers.

Television 1939 RCA Early Introduction to TV

"Early promotional film introducing TV to the American public, probably coordinated with the rollout of scheduled broadcasting at the 1939 New York World's Fair. Shows scenes of television production at the National Broadcasting Company (NBC) studios at Rockefeller Center, New York City, using equipment manufactured by NBC's corporate parent RCA."

Public domain film from the Library of Congress Prelinger Archive, slightly cropped to remove uneven edges, with the aspect ratio corrected, and mild video noise reduction applied.The soundtrack was also processed with volume normalization, noise reduction, clipping reduction, and equalization.
In its early stages of development, television employed a combination of optical, mechanical and electronic technologies to capture, transmit and display a visual image. By the late 1920s, however, those employing only optical and electronic technologies were being explored...
The first images transmitted electrically were sent by early mechanical fax machines, including the pantelegraph, developed in the late nineteenth century. The concept of electrically powered transmission of television images in motion was first sketched in 1878 as the telephonoscope, shortly after the invention of the telephone...
The idea of using scanning to transmit images was put to actual practical use in 1881 in the pantelegraph, through the use of a pendulum-based scanning mechanism... scanning... is the concept of "rasterization", the process of converting a visual image into a stream of electrical pulses.
In 1884 Paul Gottlieb Nipkow, a 23-year-old university student in Germany, patented the first electromechanical television system which employed a scanning disk, a spinning disk with a series of holes spiraling toward the center, for rasterization. The holes were spaced at equal angular intervals such that in a single rotation the disk would allow light to pass through each hole and onto a light-sensitive selenium sensor which produced the electrical pulses. As an image was focused on the rotating disk, each hole captured a horizontal "slice" of the whole image.
Nipkow's design would not be practical until advances in amplifier tube technology became available. The device was only useful for transmitting still "halftone" images—represented by equally spaced dots of varying size—over telegraph or telephone lines. Later designs would use a rotating mirror-drum scanner to capture the image and a cathode ray tube (CRT) as a display device, but moving images were still not possible, due to the poor sensitivity of the selenium sensors. In 1907 Russian scientist Boris Rosing became the first inventor to use a CRT in the receiver of an experimental television system. He used mirror-drum scanning to transmit simple geometric shapes to the CRT.
Using a Nipkow disk, Scottish inventor John Logie Baird succeeded in demonstrating the transmission of moving silhouette images in London in 1925, and of moving, monochromatic images in 1926... in 1927 Baird also invented the world's first video recording system, "Phonovision": by modulating the output signal of his TV camera down to the audio range, he was able to capture the signal on a 10-inch wax audio disc using conventional audio recording technology...
In 1926, Hungarian engineer Kálmán Tihanyi designed a television system...
By 1927, Russian inventor Léon Theremin developed a mirror-drum-based television system...
Also in 1927, Herbert E. Ives of Bell Labs transmitted moving images from a 50-aperture disk producing 16 frames per minute...
In 1927, Philo Farnsworth made the world's first working television system with electronic scanning of both the pickup and display devices, which he first demonstrated to the press on 1 September 1928.
WRGB claims to be the world's oldest television station, tracing its roots to an experimental station founded on January 13, 1928, broadcasting from the General Electric factory in Schenectady, NY, under the call letters W2XB...
In 1936 the Olympic Games in Berlin were carried by cable to television stations in Berlin and Leipzig where the public could view the games live...
On 2 November 1936 the BBC began transmitting the world's first public regular high-definition service...
In 1936, Kálmán Tihanyi described the principle of plasma display, the first flat panel display system.
Mexican inventor Guillermo González Camarena also played an important role in early television...
Although television became more familiar in the United States with the general public at the 1939 World's Fair, the outbreak of World War II prevented it from being manufactured on a large scale until after the end of the war. True regular commercial television network programming did not begin in the U.S. until 1948...

Richard Dawkins - Militant atheism

Biologist Richard Dawkins launches into a full-on appeal for atheists to make public their beliefs and to aggressively fight the incursion of religion into politics and education. Dawkins' scornful tone drew strongly mixed reactions from the audience; some stood and applauded his courage. Others wondered whether his strident approach could do more harm than good. Dawkins went on to publish The God Delusion and become perhaps the world's best-known atheist.

Video visar exakt vad som händer inuti vår hjärna

Video visar exakt vad som händer inuti vår hjärna

Ny bildteknik visar hjärnans ständiga förnyelse: Med hjälp av en ny teknik, har forskare skapat spektakulära videofilmer som visar hur proteinerna transporteras inuti nervceller i vår hjärna.
PUBLICERAD 24 AUGUSTI 2012 - 13:30 – UPPDATERAD 24 AUGUSTI 2012 - 16:57
Artikeltexten fortsätter längre nerHoppa till artikeltexten
Det är en häpnadsväckande inblick i det inre arbetet i hjärnan. De amerikanska forskarna använde fluorescerande proteiner från en manet för att lysa upp insidan av en nervcell i hjärnan och på så sätt fånga filmsekvenser som visar hur proteinerna, kroppens byggstenar, transporteras i cellen. I videon här kan de ses som svarta prickar som flyttar runt inuti cellen.
"Nu kan vi se det vi vet"
- Din hjärna plockas ner bit för bit och byggs ihop igen varje dag. Om en vecka från idag, kommer din hjärna att bestå av helt andra proteiner än den gör i dag. Den här videon visar processen. Vi har vetat att det sker, men nu kan vi se när det sker, säger forskaren Don Arnold, på University of Southern California.
Den nya bildtekniken användes för att kasta nytt ljus över hur proteiner dirigeras till en av de två typerna av avdelningar inuti en nervcell i hjärnan: axonet eller dendriter. Axonet är den del av cellen som ansvarar för att sända ut elektriska signaler till andra celler i kroppen, medan dendriterna tar emot signaler från andra celler.
- Det har varit känt i många decennier att proteiner dirigeras till den ena eller den andra avdelningen. Men vi kunde inte förstå hur den dirigeringen gick till förrän vi faktiskt kunde se när proteinerna rör sig till den ena avdelningen eller den andra, säger Sarmad Al -Bassam på USC, huvudförfattare till studien.
Mycket svårt att se
- Det är väldigt väldigt smått det här. Om en nervcell var så stor som globen skulle den kunna ha en nervtråd (axon) lika tjock som en trädgårdsslang som nådde till Barcelona och sedan förgrenade sig i norra Spanien. Samtidigt skulle den ha andra nervtrådar, dendriter som täckte hela Storstockholm, säger Lars Olson, professor i neurobiologi på Karolinska Institutet.
För att proteiner snabbt ska kunna transporteras runt i kroppen så får de lift de med vesikler - mycket små blåsor somfärdas fram och tillbaka i axonet. Man kan jämföra dem med mikroskopiska lastbilar som nervcellen laddar med olika proteiner och skickar ut med olika uppgifter i kroppen, på små motorvägar inuti axonet.
- De sänds ut med proteiner till de yttersta ändarna av nervcellens nervtrådar och samlar även upp information där ute, som transporteras tillbaka till dendriterna i nervcskroppen. Det som är nytt här är att forskarna kan visa den sorteringsmekanism som finns i mynningen till axonet. I videon kan vi se hur blåsorna med proteiner som ska till en dendrit stannar upp ett tag om de istället råkar komma till axonet och sedan vänder för att hitta rätt. Det är inte blåsorna som vet vart de ska utan det är den här "silen" i axonet som avgör vilket protein som ska få komma igenom spärren och fortsätta ut i axonet, säger Lars Olson.
Ny förståelse för hjärnans utveckling
Genom att använda det fluorescerande proteinet GFP (green fluorescent protein) från maneter har forskare kunnat märka upp och se proteiner inuti celler, inklusive hjärnceller, sen mitten av 90-talet. År 2008 fick tre forskare ta emot nobelpriset för upptäckten och utvecklingen av GFP.
Men problemet när man lyst upp proteinernas vägar på det här sättet har varit att det finns flera överlappande vägar i cellen, vilket gör det svårt att se proteinernas rörelser i en enda cell. I den här nya forskningen löste man det genom en ny teknik där man lyckades ladda ett stort antal blåsor med samma protein och få dem att börja sin vandring i cellen samtidigt genom att först dämma upp systemet. Blåsorna laddade forskarna dels med proteiner, som antingen skulle till dendriter eller till axonet, och dels med GFP. Och när man sedan släppte fördämningen, med hjälp av ett speciellt protein, kunde man lättare följa den här samlade mängden blåsor och proteiner, och hur sorteringsmekanismen gick till just där axonet utgår från nervcellkroppen.
Enligt forskarna kan den här nya inblicken leda till bättre förståelse för hur vår hjärna fungerar.
- Det här är överraskande resultat. Forskarna har här på ett elegant sätt visat hur proteinerna rör sig i en nervcell och sorteras in i - eller bort från - axonet. Det kan även öka förståelsen för hur sjukdomar skadar nervceller, säger Lars Olson.
