Science Is a Fundamental Part of America

August 3, 2017

Neil deGrasse Tyson:

“How did America rise up from a backwoods country to be one of the greatest nations the world has ever known? We pioneered industries. And all this required the greatest innovations in science and technology in the world. And so, science is a fundamental part of the country that we are. But in this, the 21st century, when it comes time to make decisions about science, it seems to me people have lost the ability to judge what is true and what is not, what is reliable what is not reliable, what should you believe what you do not believe. And when you have people who don’t know much about science standing in denial of it and rising to power, that is a recipe for the complete dismantling of our informed democracy.”

Did Comets Prepare Earth for Life?

February 9, 2017

Did Comets Prepare Earth for Life?

One of the big Space stories last year involved the European Space Agency’s Rosetta mission to the comet 67P/Churyumov-Gerasimenko.  Data from the mission found that the 2.5 mile long “dirty snowball” orbiting the sun every 6.44 years contains not just frozen water and water vapor but the mineral phosphorus and the amino acid glycine, two more of the building blocks of life.

Space Aliens Communicate With Earth. Maybe.

January 3, 2017

Space Aliens Communicate With Earth. Maybe.

“Two Canadian astronomers published a study that claims an anomaly in the pulsing of a group of stars is possibly evidence of an alien civilization. ….

The scientists Ermanno Borra and Éric Trottier from the Université Laval in Quebec analyzed modulations in 2.5 million stars from the Sloan Digital Sky Survey project and concluded that 234 of them exhibited strange behavior. In fact, the stars seemed to be signaling, with the conceivable explanation that it’s aliens trying to make contact.”

— “Astronomers Detect Strange Star Signals That Are ‘Probably’ Aliens Making Contact,” Paul Ratner, Big Think

More:

“Either stars are strange, or there are 234 aliens trying to contact us,” Evan Gough, Universe Today via Phys.org

Trump on Science

September 13, 2016

Trump on Science
Anti-vaxxer and GOP presidential candidate Donald J. Trump believes climate change is a Chinese hoax meant to make American industry less competitive and reduce the effectiveness of his own hairspray. Mr. Trump’s campaign is so anti-science that Scientific American magazine (founded 1845)  published a column noting that, in politics, “facts have become an undervalued commodity”:

“When the major Republican candidate for president has tweeted that global warming is a Chinese plot, threatens to dismantle a climate agreement 20 years in the making and to eliminate an agency that enforces clean air and water regulations, and speaks passionately about a link between vaccines and autism that was utterly discredited years ago, we can only hope that there is nowhere to go but up.”

— “Donald Trump’s Lack of Respect for Science Is Alarming,” Scientific American

Mr. Trumps’ words may deride global warming, but his actions tell another story. He wants permission to build sea walls to protect his coastal golf course in Ireland from sea level rise caused by climate change.
