Why can't we trust what we see? Witnesses to a "murder" were tested on their powers of recollection The human memory can be impressive, but it is equally prone to letting us down. Now groundbreaking research has revealed the extent of just how fragile it can be - and how to use it better. You're in the pub and trouble starts. It's long been accepted that eyewitness testimony may not always be as reliable as it seems. But however fallible human memory is, it's often the only thing police have to go on and eyewitnesses have been responsible for sending people to prison ever since the justice system began - both rightly and wrongly. Now research has gone further than ever before to understand the fragile nature of our powers of recall. The project - involving the Open University, the BBC and Greater Manchester Police (GMP) - is groundbreaking in several ways. 'Appalling' In this case the important action took place when they were least expecting it. 'Lifeblood' 'Empty the head' Below is a selection of your comments.
Education is Ignorance, by Noam Chomsky (Excerpted from Class Warfare) DAVID BARSAMIAN: One of the heroes of the current right-wing revival... is Adam Smith. You've done some pretty impressive research on Smith that has excavated... a lot of information that's not coming out. You've often quoted him describing the "vile maxim of the masters of mankind: all for ourselves and nothing for other people." NOAM CHOMSKY: I didn't do any research at all on Smith. I just read him. There's no research. He did give an argument for markets, but the argument was that under conditions of perfect liberty, markets will lead to perfect equality. He also made remarks which ought to be truisms about the way states work. This truism was, a century later, called class analysis, but you don't have to go to Marx to find it. The version of him that's given today is just ridiculous. But even more interesting in some ways was the index. I want to be clear about this. This is true of classical liberalism in general. It's the same when you read Jefferson. CHOMSKY: ... ...
Pitch drop experiment The University of Queensland pitch drop experiment, featuring its then current custodian, Professor John Mainstone (taken in 1990, two years after the seventh drop and 10 years before the eighth drop fell). University of Queensland experiment[edit] The eighth drop fell on 28 November 2000, allowing experimenters to calculate that the pitch has a viscosity approximately 230 billion (2.3×1011) times that of water.[2] This is recorded in Guinness World Records as the world's longest continuously running laboratory experiment, and it is expected that there is enough pitch in the funnel to allow it to continue for at least another hundred years. This experiment is predated by two other still-active scientific devices, the Oxford Electric Bell (1840) and the Beverly Clock (1864), but each of these have experienced brief interruptions since 1937. Professor Mainstone subsequently commented: Professor John Mainstone died on 23 August 2013 following a stroke. Timeline[edit] See also[edit]
England riots: Timeline and map of violence Riots in London and around the country saw widespread looting and buildings set alight. Dozens were left homeless after a night of riots on the streets of Tottenham after a peaceful demonstration on 6 August over the death of a man who was shot by police turned violent. Here is a timeline of what happened, starting with most recent events. 00:22 BST - The Metropolitan Police say 1,103 people have now been arrested in connection with the riots and 654 people have been charged. Greater Manchester Police said they had so far made 147 arrests and more than 70 people had already gone through the courts. Merseyside Police said they had made 77 arrests and charged 45 people. The night passes off peacefully - with officers still on the streets in large numbers. 21:50 BST - Metropolitan Police now say 1,009 people have been arrested in connection with the riots - and 464 have been charged so far. 20:04 BST - The debate concludes and the Commons adjourns.

(2) Three webcams trained on the experiment 24/7. (3) The Pitch Drop Experiment. (4) Close up of the pitch drop. About the Pitch Drop Experiment While the School of Mathematics and Physics at The University of Queensland has an international reputation for cutting-edge research and innovative teaching in the disciplines of Mathematics, Physics and Statistics, it is also home to the famous Pitch Drop Experiment. The experiment is listed in the Guinness Book of World Records as the world's longest-running laboratory experiment. The first Professor of Physics at UQ, Professor Thomas Parnell, began an experiment in 1927 to illustrate that everyday materials can exhibit quite surprising properties. The experiment demonstrates the fluidity and high viscosity of pitch, a derivative of tar once used for waterproofing boats. Live view of the Pitch Drop Experiment More information
Can you solve the prisoner hat riddle? - Alex Gendler The ‘prisoners and hats puzzle’ is a classic logic problem with many variants, some of which are described and summarized here. Like other puzzles where each player has information about the other players but not about themselves, they rely on inductive logic and the hierarchy of beliefs to figure out the other players’ thought processes to deduce the missing information. Just remember – if you try to stump other people with this kind of puzzle, make sure you have the right answer yourself. Love the challenge of this riddle?

Why Americans doubt man-made climate change - Inside Story: US 2012 It was 42 years ago that the first Earth Day was organised in the US, drawing millions of Americans to rallies across the country calling for a sustainable environment. Some consider that day to be the birth of the modern environmentalist movement in the US. Today the day is marked by millions around the world but its impact in the US seems to have fizzled, with only dozens turning out at the National Mall in Washington DC on Sunday. While the first Earth Day helped lead to the establishment of the US Environmental Protection agency, this year it was largely ignored by politicians and the public. The issue of climate change has barely come up on the US presidential campaign trail. And for the Republicans it is something they would rather distance themselves from. So why do most Americans still doubt that climate change is man-made?

Science Isn’t Broken If you follow the headlines, your confidence in science may have taken a hit lately. Peer review? More like self-review. An investigation in November uncovered a scam in which researchers were rubber-stamping their own work, circumventing peer review at five high-profile publishers. Scientific journals? Not exactly a badge of legitimacy, given that the International Journal of Advanced Computer Technology recently accepted for publication a paper titled “Get Me Off Your Fucking Mailing List,” whose text was nothing more than those seven words, repeated over and over for 10 pages. Taken together, headlines like these might suggest that science is a shady enterprise that spits out a bunch of dressed-up nonsense. If we’re going to rely on science as a means for reaching the truth — and it’s still the best tool we have — it’s important that we understand and respect just how difficult it is to get a rigorous result. What’s The Point: Bad incentives are blocking good science
Faller musikkens verdi? Faller musikkens verdi? Tom Skjeklesæther betrakter det som et endetidstegn at øl blir mer verdt enn musikk. Tom Skjeklesæther betrakter det som et endetidstegn at øl blir mer verdt enn musikk. (ABC Nyheter:) I sommer har debatten om musikkens fremtid, vilkår og verdi tatt fatt igjen. I takt med at det har blitt tydelig for sjefene for noen uavhengige norske plateselskaper at musikkstreamingtjenester som Spotify og Wimp, slik de opererer i dag, ikke innebærer noe vesentlig bidrag til å drive plateselskap eller å livnære seg som artist, har de bestemt seg for å trekke sine kataloger ut av Spotify. Den svenske streamingtjenesten Spotify tilbyr både gratis, reklameavbrudt lytting og abonnement. Det kan uansett være gode grunner til å reflektere over hva streamingtjenestene innebærer, også utover den umiddelbare situasjonen med minimale inntekter for opphavsmenn og selskaper.
Liquid breathing Perfluorochemical (perfluorocarbon) molecules have very different structures that impart different physical properties such as respiratory gas solubility, density, viscosity, vapor pressure, and lipid solubility.[1] Thus, it is critical to select the appropriate PFC for a specific biomedical application, such as liquid ventilation, drug delivery or blood substitutes. The physical properties of PFC liquids vary substantially; however, the one common property is their high solubility for respiratory gases. In fact, these liquids carry more oxygen and carbon dioxide than blood.[2] In theory, liquid breathing could assist in the treatment of patients with severe pulmonary or cardiac trauma, especially in pediatric cases. Approaches[edit] Computer models of three perfluorochemical molecules used for biomedical applications and for liquid ventilation studies: a) FC-75, b) perflubron, and c) perfluorodecalin.
