Forget about the science people don't know: How confident are they about what they *do* know?
We've all been treated to countless stories about how much Americans do not know about science, so the Associated Press decided not to trample over that ground yet again. Instead, it conducted a poll in which it asked respondents how confident they were about the science that they do know. The results are interesting--and confusing. "Few Americans question that smoking causes cancer. But they express bigger doubts as concepts that scientists consider to be truths get further from our own […]
AP poll has experts lamenting science literacy – It’s more complicated
Should we be surprised by this? No, I’m not. Disappointed, maybe. But, we should be used to these results by now. Poll: Big Bang a big question for most Americans. Few Americans question that smoking causes cancer. But they express bigger doubts as concepts that scientists consider to be truths get further from our own… Source: Doubtful News
L'universo spiegato a mia sorella
Non voglio fare concorrenza alla splendida spiegazione di Amedeo o a quella tecnica di Corrado, ma mia sorella, leggendo il post di pancia scritto nella sera dell'annuncio di BICEP2, ha candidamente confessato di non aver capito cosa era accaduto quel giorno. E allora proviamoci, a raccontarlo. (da The Cartoon History of the Universe #1 di Larry Gonick)C'era una volta un'idea di universo, che era la Terra al centro, quindi il Sole, la Luna e gli altri pianeti e sullo sfondo le stelle fisse, […]

How the “Gooey Universe” Could Shed Light on the Big Bang
“Interdisciplinary” is a huge buzzword in academia right now. But for science, it has a long history of success. Some of the best science happens when researchers cross-pollinate, applying knowledge from other fields to inform their research. One of the best such examples in physics was the concept of a Higgs field, which led to the […]The post How the “Gooey Universe” Could Shed Light on the Big Bang appeared first on The Crux.
Astronomers Use Quasars to Measure Expansion Rate of Early Universe
Scientists from the Baryon Oscillation Spectroscopic Survey (BOSS) have used 140,000 quasars to measure the expansion rate of the Universe when it was about 3 billion years old. The light emitted by quasars, the brightest cosmic objects found billions light-years away, passes through intervening hydrogen gas distributed throughout the Universe. The analysis of hydrogen absorption [...]
Mettere in discussione il modello cosmologico standard
Il modello cosmologico standard, o del Big Bang, è stato sviluppato grazie alle osservazioni della struttura su larga dell’Universo e ad una serie di considerazioni teoriche. Esso dipende da due […]
The Multiverse is not the answer (Synopsis)
“Physical reality does not require that we be pleased with its mechanism; we must see the implications of a theory for what they are and not for what we would like them to be.” -Kevin Michel If you’ve been following along for a while — particularly in light of the recent BICEP2 results — you’re…
ScienceNOW: AF modes, the pain, the parody, and it's that time of year....
Just a quickie here. One finds sheer genius in this seasonal story. Don't know which is keenest, the AF modes hidden beneath the B modes in the microwave sky where inflation's blow-up gravity waves are splayed wide, or the deflaton (DEF-luh-ton). It had me going for several graphs, until Blutarsky showed up. ScienceNOW - Adrian Cho, Richard Stone: Scientists Find Imprint of Universe That Existed Before the Big Bang;   Science's reporters have several of this sort up but this one seemed […]
