Testing for a Holographic Universe
Is our universe simply a hologram? Particle astrophysicist Craig Hogan is building the most precise clock of all time to directly measure whether our reality is an illusion.
"In 2008, Fermilab particle astrophysicist Craig Hogan made waves with a mind-boggling proposition: The 3D universe in which we appear to live is no more than a hologram. Now he is building the most precise clock of all time to directly measure whether our reality is an illusion. The idea that spacetime may not be entirely smooth—like a digital image that becomes increasingly pixelated as you zoom in—had been previously proposed by Stephen Hawking and others. Possible evidence for this model appeared last year in the unaccountable 'noise' plaguing the GEO600 experiment in Germany, which searches for gravitational waves from black holes."

Even some teachers suffer from anxiety about math.
I teach people how to teach math, and I've been working in this field for 30 years. Across those decades, I've met many people who suffer from varying degrees of math trauma – a form of debilitating mental shutdown when it comes to doing mathematics.
She met mere mortals with and without the Vatican's approval.
- For centuries, the Virgin Mary has appeared to the faithful, requesting devotion and promising comfort.
- These maps show the geography of Marian apparitions – the handful approved by the Vatican, and many others.
- Historically, Europe is where most apparitions have been reported, but the U.S. is pretty fertile ground too.
The legacy of Felix Dzerzhinsky, who led Soviet secret police in the "Red Terror," still confounds Russia.
- Felix Dzerzhinsky led the Cheka, Soviet Union's first secret police.
- The Cheka was infamous for executing thousands during the Red Terror of 1918.
- The Cheka later became the KGB, the spy organization where Russia's President Putin served for years.
