Best Explanation of Quantum Field Theory That You Will Ever Hear

Below you will find an excellent lecture by Dr. Sean Carroll delivered on 12 June 2013 at the 46th Annual Fermilab Users Meeting, focusing on the importance of the discovery of the Higgs boson confirming the existence of the Higgs field – giving us a glimpse into the world of “Particles, Fields and The Future of Physics”.

For me, the highlight of the lecture occurred during the question and answer period, at approximately 1:14:32, when one of the members of the audience asked the following question:

Question: “So, could you explain a bit more on measurement? You said that you have wave and it interacts with an entangled amount of waves and then pops out a particle, right?

I found the following response by Dr. Carroll to be the best description of quantum field theory that I have ever come across:

Sean Carroll: “Yes.

Daniele Bolelli: The Drunken Taoist Takes On Gnosis

The following is from the new book, THE QUEST FOR GNOSIS, available now.Dan22

Mr. Bolelli is the author of the book, Create Your Own Religion: A How To Book Without Instructions. His perspective on life, death and everything in between has always intrigued and inspired me and I just had to have a talk with him for The Quest For Gnosis.

GDR: So… you’re called the “Drunken Taoist.”

DB: Sure.

GDR: Why is that? What’s the story behind that?

DB: Um… Drunken Taoist I guess, you know how in kung fu movies you’ve got the old drunk guy who looks like crap and always manages to defeat these burly, strong, younger, better, faster attackers and nobody can quite figure out how. The Drunken Taoist is the power of weirdness: It’s an unorthodox approach, that no one can quite figure out why it works, but it does.

GDR: Right.… Read the rest

Are We Hard-Wired To Believe In Life After Death?

spaceface-RAScienceDaily on a study suggesting that the conviction that our souls will survive beyond death is a feeling that emerges intuitively:

Most people believe they are immortal. That is, that part of themselves-some indelible core, soul or essence-will transcend the body’s death and live forever. But why? And why is this belief so unshakable?

A new Boston University study published in Child Development  suggests that our bias toward immortality is a part of human intuition that naturally emerges early in life. And the part of us that is eternal, we believe, is our hopes, desires and emotions.

Researchers have long suspected that people develop ideas about the afterlife through cultural exposure, like television or movies, or through religious instruction. But perhaps, thought Emmons, these ideas of immortality actually emerge from our intuition. Just as children learn to talk without formal instruction, maybe they also intuit that part of their mind could exist apart from their body.

Hunter S. Thompson’s Superb Advice on How to Find Your Purpose and Live a Meaningful Life

Hunter S. Thompson graffiti 2Maria Popova takes a look at the advice of Hunter S. Thompson given in a letter to a friend when he was 20-years-old. From Brain Pickings:

As a hopeless lover of both letters and famous advice, I was delighted to discover a letter 20-year-old Hunter S. Thompson — gonzo journalism godfather, pundit of media politics, dark philosopher — penned to his friend Hume Logan in 1958. Found in Letters of Note: Correspondence Deserving of a Wider Audience (public library) — the aptly titled, superb collection based on Shaun Usher’s indispensable website of the same name — the letter is an exquisite addition to luminaries’ reflections on the meaning of life, speaking to what it really means to find your purpose.

Cautious that “all advice can only be a product of the man who gives it” — a caveat other literary legends have stressed with varying degrees of irreverence — Thompson begins with a necessary disclaimer about the very notion of advice-giving:

To give advice to a man who asks what to do with his life implies something very close to egomania.

A New Physics Theory of Life

Natalie Wolchover writes at Quanta:

Why does life exist?

Popular hypotheses credit a primordial soup, a bolt of lightning and a colossal stroke of luck. But if a provocative new theory is correct, luck may have little to do with it. Instead, according to the physicist proposing the idea, the origin and subsequent evolution of life follow from the fundamental laws of nature and “should be as unsurprising as rocks rolling downhill.”

From the standpoint of physics, there is one essential difference between living things and inanimate clumps of carbon atoms: The former tend to be much better at capturing energy from their environment and dissipating that energy as heat. Jeremy England, a 31-year-old assistant professor at the Massachusetts Institute of Technology, has derived a mathematical formula that he believes explains this capacity. The formula, based on established physics, indicates that when a group of atoms is driven by an external source of energy (like the sun or chemical fuel) and surrounded by a heat bath (like the ocean or atmosphere), it will often gradually restructure itself in order to dissipate increasingly more energy.

Bill Nye, Brian Greene, Neil deGrasse Tyson and Lawrence Krauss on the Limitations of Mathematics

MATHEMATICS-INVENTED-OR-DISCOVERED-facebookvia chycho
Math lovers and aficionados will find the following discourse both entertaining and informative.

Below you will find the video and partial transcript of Arizona State University’s Origins Project’s Q&A segment from their ‘The Storytelling of Science’ panel discussion, featuring “well-known science educator Bill Nye, astrophysicist Neil deGrasse Tyson, evolutionary biologist Richard Dawkins, theoretical physicist Brian Greene, Science Friday’s Ira Flatow, popular science fiction writer Neal Stephenson, executive director of the World Science Festival Tracy Day, and Origins Project director Lawrence Krauss.”

The first question asked of the panel was:

Q: “If you could give us all a one word piece of advice for our own science storytelling, what would it be?”

Bill Nye was the first to reply with, “Algebra, learn algebra.” Neil deGrasse Tyson follows with, ‘Ambition’. Lawrence Krauss with, ‘Passion’. Neal Stephenson with, ‘Empathize’. Richard Dawkins states that since empathize has already been taken, he will choose ‘Poetry’.

Slime Mold Expresses Its Emotions Through Robotic Face

Android technology may reveal the inner lives of simple and mysterious creatures, in disturbing fashion. Via New Scientist:
Slime mold finds the quickest path between food and has even shown signs of having memory – despite not having a brain. A human-like robot face has been hooked up so that its expressions are controlled by the electrical signals produced when yellow slime mold shies away from light, or moves eagerly towards food. Physarum polycephalum is a common yellow slime mold which ranges in size from several hundred micrometres to more than one metre. It is an aggregation of hundreds or thousands of identical unicellular organisms that merge together into one huge "cell" containing all their nuclei.
