How awesome is the picture in this article

"The ultimate responsibility for our nation's policy rests on its citizens and they can discharge such responsibilities wisely only if they are informed. The average citizen cannot be expected to understand clearly how an atomic bomb is constructed or how it works but there is in this country a substantial group of engineers and scientists who can understand such things and who can explain the potentialities of atomic bombs to their fellow citizens. The present report is written for this professional group and is a matter-of-fact, general account of work in the USA since 1939 aimed at the production of such bombs."The report addresses three major areas that I find particularly interesting while occasionally providing a glimpse into the personalities and ideologies of the (mostly non-military scientists involved with the Manhattan Project. First, its treatment of the science behind the bomb is interesting because it is both accessible and built on first principles. Rarely has such such massive research been undertaken, and the focus on applicability rather than "pure science" is easily apparent throughout the report. Lots of space is dedicated to the tension between scientific principles and industrial capacity. In fact, I was surprised by the set of challenges faced. Drawing a blueprint of an atomic bomb turns out to be fairly easy; learning how to refine the fissionable material, manufacture precision explosives, etc turns out to be the limiting factor. Interestingly, this is still true today; Iran is not limited by its technological understanding but instead by its limited industrial capacity.
"This arrangement was very successful in preventing publication and was still nominally in effect, in modified form, in .June 1945 Actually the absorption of most physicists in this country into war work of one sort of another soon reduced the number of papers referred to the committee practically to the vanishing point, It is of interest to note that this whole arrangement was a purely voluntary one; the scientists of the country are to be congratulated on their complete cooperation. It is to be hoped that it will be possible after the war to publish these papers at least in part so that their authors may receive proper professional credit for their contributions."Another interesting nugget is the developing tension, even then, between American heros and French surrender monkeys. In the spring of 1939, Neils Bohr led a coalition of eminent U.S. scientists who voluntarily agreed to cease publishing relevant papers; this arrangement failed, however, due to the refusal of "F. Joliot, France's foremost nuclear physicist, apparently because of the publication of one letter in the Physical Review sent in before all Americans had been brought into the agreement. Consequently publication continued freely for about another year although a few, papers were withheld voluntarily by their authors." In it's discussion of the project's administrative history, the report helps us learn a bit more about some of the leading scientists and military leaders. Their wisdom comes through most clearly in report's summary, however.
"Because of the restrictions of military security there has been no chance for the Congress or the people to debate such questions. They have been seriously considered by all concerned and vigorously debated among the scientists, and the conclusions reached have been passed along to the highest authorities. These questions are not technical questions; they are political and social questions, and the answers given to them may affect all mankind for generations. In thinking about them the men on the project have been thinking as citizens of the United States vitally interested in the welfare of the human race. It has been their duty and that of the responsible high government officials who were informed to look beyond the limits of the present war and its weapons to the ultimate implications of these discoveries. This was a heavy responsibility. In a free country like ours, such questions should be debated by the people and decisions must be made by the people through their representatives. This is one reason for the release of this report. It is a semi-technical report which it is hoped men of science in this country can use to help their fellow citizens in reaching wise decisions. The people of the country must be informed if they are to discharge their responsibilities wisely."More than anything, this leaves me nostalgic for a government I feel like I can trust. This attitude is woefully missing from our government today, which instead reflexively hides anything the least bit controversial. I hope that future administrations will recognize the essential role an active and educated populace plays in creating good government, but frankly, I'm not optimistic.
First, we simulate gamblers that follow Martingale strategies in a Crash recreation. Starting from a minimum guess of 1, we multiply wagers by a ratio γ every time the gamblers lose one round and return to the minimum guess every time they win. Once the wager reaches a preset most guess value ten thousand, we reset the gambler with a minimum guess. MSD obtained from 10 billion 코인카지노 particular person simulations is shown in Fig.8. Different curves correspond to different exponents in odds distribution. We can see that the MSD initially presents an exponential-like progress, earlier than the growths scale back to a linear function.
"Barack Obama received 278,966 more votes that Hillary Clinton. Given that 423,123, the lower bound of the estimated impact of the endorsement is greater than this difference, the results suggest that Oprah's endorsement was responsible for the difference in the popular vote between Barack Obama and Hillary Clinton."The study used 'O' magazine subscription data as a proxy for Oprah's influence. The authors found that this variable was significantly positively correlated with both votes cast for Obama and overall turnout (both .95 confidence).
"For example, a 10% change in the county-level circulation of 'Oprah' is associated with an increased vote share for Obama of approximately .2 percentage points... In total, we estimate that the endorsement was responsible for 1,015,559 votes for Obama."As a point of reference, county wide voting results were more influenced (per individual) by gender, age, and education than 'O' readership. Subscriptions were more predictive than factors like veterans population, urban/suburban mix, or unemployment, however. Holy Shit.
Documentarian Errol Morris, (The Fog of War, A Brief History of Time), keeps a thought-provoking blog in the New York Times about photography and the implications of the medium.
He recently wrote about the cognitive phenomenon of “inattentional blindness,” where our visual systems prove to be pretty picky eaters. Even when we think we’re visually focused — watching a movie, or just observing the world around us, obvious visual cues can pass by completely unnoticed if they’re unrelated to our immediate attentional framework.
For example, in a study done by a couple Harvard psychologists, subjects were instructed to watch a video of people standing in a circle passing a ball around and to count the number of passes the white team made. Afterwards, they were asked if they saw anything out of the ordinary. Most people said no.
Then they were told to go back and check out the fact that in the middle of the scene, who walks by, but a GUY IN A FREAKING GORILLA SUIT. Haha oops, they say, slapping foreheads, stupid visual processing…
Morris relates this to how we have difficulty noticing subtle continuity errors in films (eg: guy wearing a different shirt in one cut to the next). Ultimately it may be the cognitive basis for our tendencies toward linear narrative, and our ability to fill in the blanks and to imagine human intentionality and causal sequencing when movies really are illusionary, constructed of fragments.
He uses examples such as Luis Buñuel’s “That Obscure Object of Desire, ” where two different actresses play one character, each appearing periodically, until by the end they switch shot by shot.
The essays Errol Morris has written for this blog are absolutely fascinating, especially this one about his journey to discover the temporal authenticity of a set of photographs from the Crimean War.
Also, here are some more wicked amazing videos from various inattentional blindness experiments. Be cool; try them on your friends!
Awesome! I was wondering if their new album would be any good...you get suspicious after such a long silence.
Thanks very nice blog! netflix account
Hello. This post is likeable, and your blog is very interesting, congratulations :-). I will add in my blogroll =). If possible gives a last there on my blog, it is about the Aluguel de Computadores, I hope you enjoy. The address is http://aluguel-de-computadores.blogspot.com. A hug.
