“On what can we now place our hopes of solving the many riddles which still exist as to the origin and composition of cosmic rays?” –Victor Francis Hess It’s often said that advanced in physics aren’t met with “eureka!” but rather with “that’s funny,” but the truth is even stranger sometimes. Rather than the scientific method of:…

“I was born not knowing and have had only a little time to change that here and there.” -Richard Feynman Scientists have long had a reputation for being uptight, serious, and even killjoy personalities. But 50+ years ago, Richard Feynman was forcing everyone who felt that way to challenge their assumptions. With his brash attitude…

“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…

“Designing a station with artificial gravity would undoubtedly be a daunting task. Space agencies would have to re-examine many reliable technologies under the light of the new forces these tools would have to endure. Space flight would have to take several steps back before moving forward again.” -Andy Weir Ever wonder, in those science fiction…

“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…

“If the doors of perception were cleansed every thing would appear to man as it is, Infinite. For man has closed himself up, till he sees all things thro’ narrow chinks of his cavern.” -William Blake When it comes to the ultimate question of the size of the Universe, we have to look to greater…

“It’s hard to build models of inflation that don’t lead to a multiverse. It’s not impossible, so I think there’s still certainly research that needs to be done. But most models of inflation do lead to a multiverse, and evidence for inflation will be pushing us in the direction of taking [it] seriously.” -Alan Guth…

“Right is right even if no one is doing it; wrong is wrong even if everyone is doing it.” -Augustine of Hippo Science isn’t the easiest endeavor you can undertake. Sure, the rewards are tremendous: you can wind up understanding any phenomenon in the Universe as well (or better) than any human has ever understood…
