Most people think that Star Trek-style nuclear rockets are a thing of the future, but the fact is we had them in the 1960s... and gave up on them.
I've seen this before. It is really a simple trick when you understand the problem from a structural engineering perspective. The trick consists of a moderate amount of power and speed, and a lot of careful selection of the target material and geometry.
Astronomers have known about these objects for decades, but in the depths of cosmic time, it's hard to understand how they can grow so quickly -- or maybe not!
The sun is a stormy star that, across the centuries, has gifted our Earth with some incredible moments of calamity. Telegraph and radio technologies and even satellites and human safety have been placed in the breach of near-destruction. Is there a major "superstorm" in our future?
What if Dr. Townes, instead of taking that timeout, had sent a text or played Angry Birds? Might we be in the dark about the laser? As research and Townes' example suggest, the unpredictable sparks of our own mental machinations should be something we don't want to miss any more than the majestic sight of a passing whale.
Most people try to power through and hammer their way past the barriers. The problem with this strategy is that you're still dealing with the other force. I find it to be much less stressful to cut out the opposing forces and let your productivity naturally flow forward.
Countless elements pulling together into one form, directed by will, energy. Science tells us that we are matter; theologians say that we are spiri...
Astronomers have been waiting for this for a long time, and at some time in the not so distant future the brilliant red star in the constellation Orion will explode. What will it look like?
In another few months the Large Hadron Collider will be powered up to explore its maximum energy range. Many physicists fervently hope we will see definite signs of "new physics," especially a phenomenon called "supersymmetry."
I was able to speak with Lisa Bruce about what compelled her to make the movie Theory of Everything , and what impact the story has had on her.
A recent Hubble image of the galaxy IC 335 shows it to be a star-filled galaxy with a flat shape not unlike our own Milky Way. But whereas the Milky Way contains vast collections of nebulae and dust clouds, IC 335 seems to have none. A look behind the curtain gives us clues to how two similar galaxies like IC 335 and the Milky Way could turn out so differently.
In today's topsy-turvy environment, all bets are off. Rather than focus on critical upcoming legislative elections and a major conference to help attract investments to Egypt's struggling economy, TV channels seem sidelined by matters that raise eyebrows and questions given their timing.
Sally Ride led a bifurcated life too. She didn't forget part of herself, she just chose not to present it to the world. I am fascinated by her success in transforming the world while hiding part of herself.
When spirituality and physics started to be linked, many scientists called it the use of metaphor. It couldn't literally be true that there was a Tao ...
Fifty years ago, in 1964, physicists Murray Gell-Mann at Caltech and George Zweig at CERN came up with the idea of the quark as a response to the bewildering number of elementary particles that were being discovered at the huge "atom smasher" labs sprouting up all over the world.
Physicists who scorch with tweets don't bother me. They only expose their isolation, arrogance, and self-willed blindness. The big questions about existence aren't shop talk for mathematically savvy professionals working in arcane specializations.
