As you read this, we are flying home to Los Angeles after an exhausting but exhilarating trip: 10 days, 2 continents, 3 flights, 2 trains, 4 hotels, 18 car rides, 7 panel discussions, 3 interviews, and 5 lectures between the two of us. (The circles under my eyes are now saucers.) First stop: New York City and the 2014 World Science Festival, where I joined neuroscientists David Eagleman and Dean Buonomo for a casual free-wheeling discussion on the brain, the self, free will, and consciousness, while the Time Lord (a.k.a. Caltech physicist Sean M. Carroll) flitted about debating the finer points of quantum mechanics, and also rubbed elbows with Joyce Carol Oates and E.L. Doctorow on a science and story panel (along with Steven Pinker and science writer Jo Marchant). Also, he moderated a panel on the documentary Particle Fever.

But so much more was going on! Some other highlights: The Mast Brothers Unveiled The Physics Behind Chocolate; The Biophysics Of Pie, From Crust To Core; and Botany At The Bar Delivered A Lush, Biodiverse Round Of Cocktails. Lest you think it was all food and drink related: F-&$# Traffic: From insects to Interstates. Can marching ants, schooling fish, and herding wildebeests teach us something about the morning commute? And Even Einstein Was a Fool in Love: Review of Dear Albert, a staged reading of Alan Alda's play, based on Einsteins letters, which kicked off the World Science Festival on May 28.

Then we hopped a red-eye flight to London, followed by a train to Cheltenham for the Cheltenham Science Festival. They kept us very busy at Cheltenham. Sean gave talks on the Higgs boson and the arrow of time, and spent a lot of time talking about his science consulting adventures in Hollywood. I served as a judge for the semifinals of the Famelab Competition, gave a talk on my book, Me, Myself and Why, engaged in a science question time, and moderated a fascinating panel on brain stimulation featuring cognitive neuroscientist Vince Walsh and bioethicist Ilina Singh. Related to my Cheltenham panel: Zapped: how applying electricity to your head might ease pain, improve memory and attention. Also: What Happens If You Apply Electricity to the Brain of a Corpse?

But our work was not yet done! On Thursday it was back to London, where the Time Lord and I teamed up to give our first-ever dual talk on the black hole firewall paradox, once at Imperial College and again that evening at the Royal Institution. Apparently we are the first husband-wife team to speak in that famous room (where my physics hero, Michael Faraday, first demonstrated induction) since Pierre and Marie Curie -- and Marie was not allowed to speak (!). I was both honored and hugely intimidated, but I think it went well.

The next day, Royal Institution documentation manager Jane Harrison and curator of collections Charlotte New gave me a tour of Faraday's lab and some of the original notebooks, etc. they have in their archives -- including the bound volume a young Faraday made from his notes on Humphrey Davy's lectures, which inspired Davy to hire him -- and we geeked out over the awesomeness of science history. Thanks to them for spending so much time with me; it was a major highlight of an action-packed trip.

Look closely: these are not flocks of birds, they are flocks of plastic bags. French photographer Alain Delorme has an eye-popping new series. "I took photos of plastic bags individually [using] a light box to get the bags transparency. There is a different bag for every swarm, shot 150 to 200 times. I then duplicated the bags, so in total you have at least 10,000 bags per image."

The internet is made of cats and you can blame economists, thanks to the Allen-Alchian theorem:

"Its all about relative costs. When you move something, or impose any fixed cost, the higher-quality item always wins, because it now has a lower relative cost compared to the lower-quality item. The interesting idea is that this also applies in reverse namely when we remove a fixed cost. The internet does this: it removes a cost of transport, and it does so equally for high quality and low quality content. Following the Allen-Alchian theorem, this should mean the opposite. Low-quality items are now relatively cheaper and high-quality items are now relatively more expensive. This idea was first explained by Tyler Cowen, but the upshot is that the internet is made of cats."
