Rank #1: AaS! 115: Is String Theory Worth It? (Part 1: Unify This!).
How did String Theory get started? What has made the idea so popular over the decades? Can we ever truly have a theory of quantum gravity? What is supersymmetry, the landscape, and the AdS/CFT Correspondence? What do holograms have to do with this? How many dimensions do we live in? Why does String Theory have such a hard time making predictions? How are we supposed to judge a theory that isn’t done yet? It’s a non-stop String Theory bonanza as I discuss these questions and more in today’s Ask a Spaceman!

The Science of Everything Podcast

In this podcast I discuss a variety of topics in both the natural and social sciences, exploring the many fascinating insights that the scientific method yields about the world around us.

Rank #1: Episode 57: Electric Current and Circuits.
We begin with adiscussion of basic electrical phenomena such as current, voltage, resistanceand power, before applying these ideas to the analysis of circuits, includingseries and parallel circuits. We then apply these concepts to understand anumber of interesting phenomena, including light bulbs, lightning, and whyelectricity can be dangerous. Recommended pre-listening is Episode 43: ElectricForces and Fields.

Rank #2: Episode 61: Magnetism.
A discussion of thebasic concepts of magnetism, including magnetic fields, magnetic poles, andelectromagnets. I also discuss the ultimate subatomic source of magnetic forcein the phenomenon of electric spin, and explain how this leads to the differenttypes of magnetic materials: ferromagnets, paramagnets, and diamagnets. Iconclude with some applications of electromagnetism, including electricgenerators and motors, transformers, and a brief discussion of Maxwell'sequations.

Big Picture Science

The surprising connections in science and technology that give you the Big Picture. Astronomer Seth Shostak and science journalist Molly Bentley are joined each week by leading researchers, techies, and journalists to provide a smart and humorous take on science. Our regular "Skeptic Check" episodes cast a critical eye on pseudoscience.

Rank #1: Before the Big Bang.
ENCORE It’s one of the biggest questions you can ask: has the universe existed forever? The Big Bang is supposedly the moment it all began. But now scientists wonder if there isn’t an earlier chapter to our origin story. And maybe chapters before that! What happened before the Big Bang? It’s the ultimate prequel. Plus – the Big Bang as scientific story: nail biter or snoozer? Guests Roger Penrose – Cosmologist, Oxford University Sean Carroll – Theoretical physicist, Caltech, author of The Particle at the End of the Universe: How the Hunt for the Higgs Boson Leads Us to the Edge of a New World Simon Steel – Astronomer, Tufts University Andrei Linde – Physicist, Stanford University Jonathan Gottschall – Writer, author of The Storytelling Animal: How Stories Make Us Human Marcus Chown – Science writer and cosmology consultant for New Scientist magazine Descripción en español First released December 17, 2012

Rank #2: Big Questions Somewhat Answered.
Here are questions that give a cosmologist – and maybe even you – insomnia: What happened after the Big Bang? What is dark matter? Will dark energy tear the universe apart? Let us help you catch those zzzzs. We’re going to provide answers to the biggest cosmic puzzlers of our time. Somewhat. Each question is the focus of new experiments that are either underway or in the queue. Hear the latest results in the search for gravitational waves that would be evidence for cosmic inflation, as well as the hunt for dark matter and dark energy. And because these questions are bigger than big, we’ve enlisted cosmologist Sean Carroll as our guide to what these experiments might reveal and what it all means. Guests: •   Sean Carroll – Cosmologist, California Institute of Technology •   Jamie Bock – Experimental cosmologist at the California Institute of Technology and NASA’s Jet Propulsion Laboratory and a member of the BICEP team •   Brendan Crill – Cosmologist at NASA’s Jet Propulsion Laboratory and member of the Planck collaboration •   Jeff Filippini – Post-doctoral Fellow, California Institute of Technology, assistant professor of physics at the University of Illinois and member of the Spider team •   Neil Gehrels – Astrophysicist at NASA’s Goddard Space Flight Center, project scientist for WFIRST

Science... sort of

Conversations about things that are science, things that are sort of science, and things that wish they were science.A member of the Brachiolope Media Network.

Rank #1: Ep 229: Science... sort of - Inherit the Earth.
00:00:00 - Way way back in the 1980's some scientists found a... thing. No this isn't the start of an excellent John Carpenter movie, it's something that happened in real life! Only this year did someone get around to describing the thing, and it turns out they couldn't. Does this new animal deserve a new phylum all to itself? Listen and decide for yourself! 00:22:54 - Ethanol is a great way to preserve specimens when done properly. It's also a great way to socialize, but again, only when used properly. Here are three examples of its proper use. Charlie kicks back a Phosphorescent Pale from the sentimental Island Hoppin' Brewery, near where he got hitched. Patrick enjoys a Devils Tale collaboration from Devil's Backbone Brewing Company and Coronado Brewing Company. He's come so far from his early days as a hops detractor. Ryan claims the greatest beer in the history of the show, a bold claim but can he pull it off? You be the judge, for he sups a Camarasaurus Cream Ale from Fossil Brewing Company! 00:30:31 - Speaking of ruling the drinks segment, who really rules the earth? And, assuming humans are dominant now, who takes over when we're gone? A think piece from LiveScience prompts a free-wheeling discussion that ends in an obvious answer (hint: AI). In other news, new species of hominids keep popping up basically all the time. That's cool . Unless any of this isn't even real, and then who really cares, right? 01:20:15 - PaleoPOWs are a lot like AI, once turned on it's difficult to get them to stop. Patrick presents a new recurring donation from Steven C. Thanks Steven! Charlie also has a donation to pair with a story and a few questions from the UNGA. The story is touching, and the questions are hard. Namely, what ultimately controls the tree line? It's not at all simple, but the guys take a stab at it. Finally, Ryan has an easier question about how solar panels work from Mike S. And a quick message to all parents of 4th graders: This school year you all get into any US National Park unit for FREE! Check out the details here: Every Kid In A Park. Thanks for listening and be sure to check out the Brachiolope Media Network for more great science podcasts!

Rank #2: Ep 60: Science... sort of - Serialized Science.
00:00:00 – The Paleopals introduce themselves as the familiar Patrick, Charlie and Ryan but rounding out the quintet today are Zach and Kelly Weinersmith (it's ok to laugh) of Saturday Morning Breakfast Cereal and Weirnersmith.com. Drinks are varied and Zach throws a true curveball the likes of which the podcast has never seen. Tune in to find out! 00:05:39 – We chat with the comedic-science super couple Zach and Kelly Weinersmith (it's ok to laugh) about their various internet incarnations. Jokes are told, science is explained, and Patrick freaks out thinking he's got a parasite even though he probably doesn't. (Key word: Probably) 00:42:28 – Trailer Trash Talk this week skirts the edge of the appropriate as the Paleopals discuss, Four Lions, the new comedy about British terrorists. Fortunately for all involved there are barely any accents attempted. 00:57:03 – Stories and statistics have more in common than one might initially be comfortable with according to John Allen Paulos in his new piece for the New York Times online. Are scientists better at literature or are the culturally literate better at science? Can it be both? Probably not. The Paleopals discuss the why's and wherefores of stories and statistics, including a brief evolutionary snippet of just how the two might have diverged oh so long ago. 01:15:35 – PaleoPOW this week is initiated by Patrick with some extra-comedic feedback from former guest of the show Brian Malow! Charlie marvels at a pumpkin-shaped Brachiolope from paleoposse member B. Nelson. Or is it a Brachiolope-shaped pumpkin? Some questions are just begging to be answered. Ryan has some self-congratulatory feedback from a recent post of his on iFanboy commented on by a new breed of listener the iFanbasus paleopalis AMuldowney.

Relatively Prime: Stories from the Mathematical Domain

A mathematics podcast from ACMEScience featuring the best math stories from the world of maths

Rank #1: 0,1,2,3….
This episode is all about the forgotten mathematical tool of numbers. Ok, forgotten may be a bit strong, but after a certain point in mathematics numbers seem to lose a bit of their importance. For the first few years after you start to learn math it is all add these numbers, divide this number by that one, or find that number. And then it morphs into for all numbers or let x be an arbitrary number or for epsilon greater than zero and numbers start to lose their power. Well not on this episode. Samuel Hansen has found stories about amazing properties of numbers, how a person started collecting collections of numbers, how research can lead to a number horde which can then lead to more research, and all about favorite numbers.

Today we’re joined here at The Star Spot by Sherry Suyu, who leads the aptly named H0LiCOW project which uses the phenomenon of gravitationally lensed quasars to measure the expansion rate of the universe. Current in Space Tony reports on a fascinating yet circumstantial finding that suggests a world literally on fire is out there, and it may excite fans of the Star Wars franchise. Then Amelia and Tony break down a study hinting at the existence of exoplanets that may be even more habitable than Earth!  About Our Guest Sherry Suyu is a Max Planck Research Group Leader at the Max Planck Institute for Astrophysics, an Assistant Professor at the Technical University of Munich, and a Visiting Scholar at the Academia Sinica Institute of Astronomy and Astrophysics.

Physics Fundamentalized

Calculus based physics for undergraduate and high school physics students.

Rank #1: Lecture 001: Inertia.
Newton’s First Law is presented in its traditional form, but strong emphasis is placed on the law as a definition of force. After a short discussion of the history of inertia and the measurement of mass, forces are presented as “a natural constraint or condition that is the cause of alteration of the motion”. The four fundamental forces of nature are described and it is noted that most everyday forces are generalized versions of the electrodynamic force. Physical contact is described as an illusion. A thought experiment is proposed in which the behavior of an object under the influence of multiple forces. Mass is defined as the measurement of inertia and noted to be directly proportional to the weight. Finally, a rough list of forces that one might encounter in physics problems is presented.

Rank #2: Lecture 044: Capacitance.
Capacitance is defined in the context of an arrangement of parallel plates. The electric field energy per unit volume is also derived.
