Today at 4:29 p.m., it’ll be like deja-vu all over again—at least for Marty McFly and fans of the Back to the Future trilogy. In part two of the popular “temporal displacement” franchise, Marty McFly (Michael J. Fox) and Doc (Christopher Llloyd) along with Jennifer (Elisabeth Shue) whisk themselves back in time via their tricked-out, time-traveling DeLorean. Their destination? October 21, 2015, a time when kids skate around on hoverboards and the Chicago Cubs win the World Series. With the Chicago Cubs in the running to make it to the World Series and hoverboards sort of a reality, Back to the Future got a few things right. In honor of the movie and the unofficial Back to the Future Day, we present a short interview with one of the movie’s producers and an infographic and two videos on time travel.

Where in New York City can you review the astonishing archives of a leading pioneer in computer language? On a velvet pillow, overlooked by a bust of a Romantic-era icon, locked in the peaceful and mysterious Pforzheimer Collection of Shelley and His Circle at the 42nd Street branch of the New York Public Library. The daughter of the poet Lord Byron, Ada’s collaboration with Charles Babbage on his calculating machine, the Analytical Engine, led to her popular reputation as the world’s first computer programmer. Modern historians have questioned whether her published notes of 1843 truly constitute the first computer language, but her writings remain unchallenged as the most exquisite poetry ever created about the intricacies of computer programming. In the early 1980’s a programming language created for the US Department of Defense was named “Ada” to honor her.

Seven days, lots of science in the news. Here’s our roundup of some of the week’s most notable and quotable items. International Space Station astronauts chowed down on salads made with lettuce that had been grown in space (accented with a simple balsamic dressing). A galactic survey confirms that our universe is “becoming a couch potato” on the way to its slow, inescapable death. MIT scientists have programmed two robots to deliver beers to bar patrons. Researchers sequenced the octopus genome. The smallest supermassive black hole ever discovered is only as massive as a mere 50,000 suns. Melting ice in Antarctica is mostly bad news, but there’s one small silver lining: It’s releasing lots of iron into the ocean that will benefit the phytoplankton occupying the bottom of the marine food chain.

Chances are, you remember Erwin Schrödinger for his famous cat, but the high point of the celebrated physicist’s career was actually unrelated to feline thought experiments. Among scientists, he’s more renowned for giving us the fundamental tools to describe quantum behavior.

Author Carl Safina’s new book Beyond Words: What Animals Think and Feel explores what animals are thinking and feeling as they go about their lives. Advances in neuroscience and extensive field observations have helped Safina to engage with questions of consciousness, anthropomorphism, and whether emotions are the unique domain of humans. We spoke with Safina about the rich inner lives of nonhuman animals he describes in the book.
