“I am looking at the future with concern, but with good hope.” –Albert Schweitzer Every so often, the argument comes up that science is expendable. That we’re simply investing too much of our resources — too much public money — into an endeavor with no short-term benefits. Meanwhile, there’s suffering of all kinds, from poverty…

“O. Hahn and F. Strassmann have discovered a new type of nuclear reaction, the splitting into two smaller nuclei of the nuclei of uranium and thorium under neutron bombardment. Thus they demonstrated the production of nuclei of barium, lanthanum, strontium, yttrium, and, more recently, of xenon and caesium. It can be shown by simple considerations…

“When we meet real tragedy in life, we can react in two ways – either by losing hope and falling into self-destructive habits, or by using the challenge to find our inner strength.” -Dalai Lama Orbiting at hundreds of miles above Earth’s atmosphere, you’d think the Hubble Space Telescope would be safe and stable for…

“This is going to have a bigger impact on science and human understanding, in many ways, than the first discovery of gravitational waves. We’re going to be puzzling over the observations we’ve made with gravitational waves and with light for years to come.” -Duncan Brown Detecting black holes and the gravitational wave signals from them…

“It’s becoming clear that in a sense the cosmos provides the only laboratory where sufficiently extreme conditions are ever achieved to test new ideas on particle physics. The energies in the Big Bang were far higher than we can ever achieve on Earth. So by looking at evidence for the Big Bang, and by studying…

“Truth in science, however, is never final, and what is accepted as a fact today may be modified or even discarded tomorrow. Science has been greatly successful at explaining natural processes, and this has led not only to increased understanding of the universe but also to major improvements in technology and public health and welfare.”…

“There are stars leaving the Milky Way, and immense gas clouds falling into it. There are turbulent plasmas writhing with X- and gamma-rays and mighty stellar explosions. There are, perhaps, places which are outside our universe. The universe is vast and awesome, and for the first time we are becoming a part of it.” -Carl…

“You were always a good officer. Until you weren’t.” -Saru, from Star Trek: Discovery Science is full of great ideas and brilliant discoveries, and some of those more recent ones have made their way into the popular consciousness. TED talks, popular blogs and online magazines, and Facebook pages and internet memes have helped disseminate bits…

“How vast those Orbs must be, and how inconsiderable this Earth, the Theatre upon which all our mighty Designs, all our Navigations, and all our Wars are transacted, is when compared to them.” -Christiaan Huygens With a field-of-view encompassing 150,000 stars, NASA’s Kepler mission delivered an overwhelming prize when it came to hunting worlds beyond…

“Wormholes are a gravitational phenomena. Or imaginary gravitational phenomena, as the case may be.” -Jonathan Nolan Yes, we detected gravitational waves, directly, for the first time! Just days after Advanced LIGO first turned on, a signal of a 36 solar mass black hole merging with a 29 solar mass black hole gave us our first…
