Famous double-slit experiment holds up when stripped to its quantum essentials
CaptionSchematic of the MIT experiment: Two single atoms floating in a vacuum chamber are illuminated by a laser beam and act as the two slits. The interference of the scattered light is recorded with a highly sensitive camera depicted as a screen. Incoherent light appears as background and implies that the photon has acted as a particle passing only through one slit. Credits:Credit: Courtesy of the researchers
MIT physicists have performed an idealized version of one of the most famous experiments in quantum physics. Their findings demonstrate, with atomic-level precision, the dual yet evasive nature of light. They also happen to confirm that Albert Einstein was wrong about this particular quantum scenario.
The experiment in question is the double-slit experiment, which was first performed in 1801 by the British scholar Thomas Young to show how light behaves as a wave. Today, with the formulation of quantum mechanics, the double-slit experiment is now known for its surprisingly simple demonstration of a head-scratching reality: that light exists as both a particle and a wave. Stranger still, this duality cannot be simultaneously observed. Seeing light in the form of particles instantly obscures its wave-like nature, and vice versa.

Robert Reich
Friends,
I’m in New York today, peddling my new book. It’s officially out today.
I loathe book tours.
The first book tour I ever went on, in the early 1980s, brought me to a bookstore in Madison, Wisconsin, where they sat me in the window under a spotlight next to a sign “Come In and Have Your Book Signed By Robert Reich.”
No one came in. For two hours, people passed on the street, a few gazing at the pathetic author in the window. I felt like a piece of merchandise, which I was.
That’s what you are when you go on a book tour: merchandise. A traveling salesperson selling a book. But not just any book — it’s your book. It’s something you’ve worked on and sweated over for several years. It’s your baby. And now you have to flog it like a can of dog food.

Adjusting to Life
Seeing the positive side is not as easy as it sounds, especially when it involves finances and/or one's health, and maybe one's relationships although that is not a critical aspect of one's life.
I remember someone telling me: HOPE FOR THE BEST, EXPECT THE WORST AND YOU ARE NEVER DISAPPOINTED... because it is always going to be one of those two. I suppose this is the humorous side of life to think like this.
When I get bad news, I immediately start to think how is this going to impact my life and what do I need to do to counter that impact. I suppose that is a good approach to take because you are not looking at it positively or negatively, just dealing with it as it happens.
When I was told I had cancer and then five years later when I was told I had contracted a second cancer, I had no positive or negative feelings; I just lived my life as if nothing was wrong. For six months, I got treatments on back-to-back days and then two days after that, I vomited so much my wife had to take me to the ER.
While throwing up that much is not very much fun and after the first time, I knew to expect it and could not stop it, I never felt MY LIFE IS OVER - THE END IS NEAR. I just dealt with it and went about living my life once it was behind me.
I don't know if the way I deal with life is the right way; I just know that the way I deal with life is the right way for me.
Moon's first-ever radio telescope ready for the dark side
Radio astronomers like a bit of peace and quiet, so they're sending an historic first radio telescope to the Moon. To block out Earthside radio signals, the Lunar Surface Electromagnetics Experiment (LuSEE-Night) will set up shop on the far side of the Moon.
Radio astronomy has revolutionized our understanding of the universe by opening up the vast electromagnetic spectrum that is invisible to the human eye. With giant radio telescopes to help, we have discovered pulsars, quasars, radio galaxies, interstellar molecules, supermassive black holes, and the microwave echoes of the Big Bang.
Unfortunately, listening to the music of the spheres is a frustrating task because Earth isn't exactly a quiet neighborhood when it comes to radio waves. Never mind terrestrial radio and television broadcasts, or even satellite signals or the ubiquitous presence of cell phones. There are also sparking car engines, microwave ovens, lightning strikes, GPS signals, reflections off the ionosphere, and even bird poop on the antenna to muck things up.
