We Need an Einstein for the 21st Century
We do at this point in time need a new Einstein. The one thing that Einstein did, which is so powerful and important in the history of physics is with special relativity he found a way to unify Newton’s laws of motion and Maxwell’s equations of electromagnetism. And then he found a way to unify that special relativity with our understanding of gravity, which is what produces general relativity.
We do, in fact, stand in a similar position now. We have two great theories of physics relativity, particularly general relativity and quantum mechanics, and they seem to paint completely different views of the world. Quantum mechanics operates at the subatomic level. General relativity tells us about the cosmological level. When you put these theories together they work in their own domains, but the pictures of the reality they paint are so fundamentally different. This is a huge problem. We live in one world. It’s called a universe. We do actually need one theory that as it were combines everything.
So we do in fact need a new synthesizer just as Einstein was able to find a very creative way to unify Newton’s laws of motion and Maxwell’s laws of electromagnetism. So we do need someone to come along and unify relativity and quantum mechanics. That’s what string theory is trying to do. Myself, I don’t believe that string theory is really, as it were, going to be proven to be the ultimate theory and there are other approaches like loop quantum gravity, which is being pioneered by the great physicist Lee Smolin. I think we do need some synthesizer and where that person will come from, I don’t know. I mean, one thing I'm certain is he’s going to come from someone who is trained seriously in physics. I don’t think it’s going to come from someone outside the mainstream, but this person will probably appear very abhorrent when they first do it.

China's Chang'e 4 biosphere experiment marks a first for humankind.
- China's Chang'e 4 lunar lander touched down on the far side of the moon on January 3.
- In addition to a lunar rover, the lander carried a biosphere experiment that contains five sets of plants and some insects.
- The experiment is designed to test how astronauts might someday grow plants in space to sustain long-term settlements.
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.
Arranged marriages and Western romantic practices have more in common than we might think.
In his book In Praise of Love (2009), the French communist philosopher Alain Badiou attacks the notion of 'risk-free love', which he sees written in the commercial language of dating services that promise their customers 'love, without falling in love'.
