Marcelo Gleiser

Marcelo Gleiser is a contributor to the NPR blog 13.7: Cosmos & Culture. He is the Appleton Professor of Natural Philosophy and a professor of physics and astronomy at Dartmouth College.

Gleiser is the author of the books The Prophet and the Astronomer (Norton & Company, 2003); The Dancing Universe: From Creation Myths to the Big Bang (Dartmouth, 2005); A Tear at the Edge of Creation (Free Press, 2010); and The Island of Knowledge (Basic Books, 2014). He is a frequent presence in TV documentaries and writes often for magazines, blogs and newspapers on various aspects of science and culture.

He has authored over 100 refereed articles, is a Fellow and General Councilor of the American Physical Society and a recipient of the Presidential Faculty Fellows Award from the White House and the National Science Foundation.

On this very day 100 years ago, while Europe was buried deep in the darkness of the Great War, Albert Einstein wrote down the equation that changed forever the way we understand space, time and matter.

I spent last week at CERN, the high-energy physics laboratory near Geneva, Switzerland, where the Higgs boson particle was discovered in July 2012.

For those who are not yet familiar, CERN houses a giant particle accelerator — the Large Hadron Collider (LHC) — a machine designed to find the smallest constituents of matter.

When discussing the relationship between science and religion, people often take a polarized position: It's either "I believe" or "I don't believe."

Much grief comes from the insistence from either side that the opposite is wrong or meaningless. (Here is an example, as secularist Sam Harris criticizes National Institutes of Health director and believer Francis Collins.)

One of the indisputable advantages of the Internet is accessibility of information, in particular for educational purposes, inside and outside schools.

Vast collections of what we photograph, study and catalogue are available by typing a few words and clicking on a few tabs. For someone who grew up scavenging local libraries to retrieve what little information was available, this accessibility is nothing short of a revolution — and an amazing one.

The notion that mechanization and technology will bring us free time, so we can "enjoy" life, is as old as technology itself.

The use of farming animals to cut through fields spared humans much hard work. Romans used watermills to grind grain and lift water for irrigation. As we advance through history, the list goes on and on. The expectation has always been that as technology and the mechanization of labor grew in sophistication, humans would have more free time and, thus, more opportunities for leisure.

On Sunday, a seven-part documentary series titled Belief begins airing on the Oprah Winfrey Network (OWN). For a week, viewers will travel around the world as the series explores the many facets of belief across cultures, from the orthodox to the secular, from the material to the spiritual.

The origin of the universe is one of the most difficult realities we ponder.

It bends our logic, straining the words we have to describe it. If one is to say the universe started at the Big Bang some 13.8 billion years ago, the immediate reaction is: "But what came before that? What caused the Big Bang?"

This is the issue of the "first cause" — the cause at the beginning of the causal chain that caused all else but was itself not caused — that has plagued and inspired philosophers for millennia.

We learned Tuesday that Takaaki Kajita, from the Super-Kamiokande Collaboration in Japan, and Arthur McDonald, from the Sudbury Neutrino Observatory Collaboration in Canada (SNO), won the 2015 Nobel Prize in physics for helping to solve a long-standing mystery in physics: the disappearing neutrinos.

This is Mars week.

First, we had the mindboggling announcement that there is strong evidence of liquid water flowing on the Martian surface. And, also this week, on Oct. 2, the much-awaited Riddley Scott movie, The Martian -- based on Andy Weir's novel and starring Matt Damon as an astronaut stranded on Mars — opens nationwide. It seems that the red planet won't play second fiddle to the moon, especially a blood red one.

On Thursday, the Boston Museum of Science will premiere The Hidden Code at the Charles Hayden Planetarium, a multimedia piece by Paul Miller (aka D J Spooky). The piece combines music, stunning visual effects and live readings to bring science to the general public in ways that only a few years ago would be unthinkable.
