Neuroscientist Explains Selective Memory (Charan Ranganath)

Neuroscientist Explains Selective Memory (Charan Ranganath)

A new understanding of memory is emerging from the latest scientific research. In Why We Remember, pioneering neuroscientist and psychologist Charan Ranganath radically reframes the way we think about the everyday act of remembering. Combining accessible language with cutting-edge research, he reveals the surprising ways our brains record the past and how we use that information to understand who we are in the present, and to imagine and plan for the future.

Memory, Dr. Ranganath shows, is a highly transformative force that shapes how we experience the world in often invisible and sometimes destructive ways. Knowing this can help us with daily remembering tasks, like finding our keys, and with the challenge of memory loss as we age. What’s more, when we work with the brain’s ability to learn and reinterpret past events, we can heal trauma, shed our biases, learn faster, and grow in self-awareness.

Including fascinating studies and examples from pop culture, and drawing on Ranganath’s life as a scientist, father, and child of immigrants, Why We Remember is a captivating read that unveils the hidden role memory plays throughout our lives. When we understand its power—and its quirks—we can cut through the clutter and remember the things we want to remember. We can make freer choices and plan a happier future.

Charan Ranganath is a Professor at the Center for Neuroscience and Department of Psychology and director of the Dynamic Memory Lab at the University of California at Davis. For over 25 years, Dr. Ranganath has studied the mechanisms in the brain that allow us to remember past events, using brain imaging techniques, computational modeling and studies of patients with memory disorders. He has been recognized with a Guggenheim Fellowship and a Vannevar Bush Faculty Fellowship. He lives in Davis, California. Outside of neuroscience, Dr. Ranganath is also a songwriter and guitarist with a number of recording credits, including a song on a feature film soundtrack.

Shermer and Ranganath discuss: how memories are stored by neurons • forgetting — memory in there somewhere or lost forever? • episodic, semantic, working, flashbulb, long-term, and short-term memory • recovered memories vs. false memories + confabulation, conflation • Alzheimer’s, dementia, senility • PTSD and bad memories • déjá vu • memory triggers • learning as a form of memory • social memories (extended self) • MEMself vs. POVself • uploading memories into the cloud • improving memory: what works, what doesn’t.

3. Dr. Arthur Benjamin — The Magic of Math: Solving for x and Figuring Out Why

3. Dr. Arthur Benjamin — The Magic of Math: Solving for x and Figuring Out Why

The Magic of Math is the math book you wish you had in school. Using a delightful assortment of examples—from ice cream scoops and poker hands to measuring mountains and making magic squares—this book empowers you to see the beauty, simplicity, and truly magical properties behind those formulas and equations that once left your head spinning. You’ll learn the key ideas of classic areas of mathematics like arithmetic, algebra, geometry, trigonometry, and calculus, but you’ll also have fun fooling around with Fibonacci numbers, investigating infinity, and marveling over mathematical magic tricks that will make you look like a math genius! A mathematician who is known throughout the world as the “mathemagician,” Arthur Benjamin mixes mathematics and magic to make the subject fun, attractive, and easy to understand. In The Magic of Math, Benjamin does more than just teach skills: with a tip of his magic hat, he takes you on as his apprentice to teach you how to appreciate math the way he does. He motivates you to learn something new about how to solve for x, because there is real pleasure to be found in the solution to a challenging problem or in using numbers to do something useful. But what he really wants you to do is be able to figure out why, for that’s where you’ll find the real beauty, power, and magic of math. If you are already someone who likes math, this Science Salon will dazzle and amuse you. If you never particularly liked or understood math, Benjamin will enlighten you and—with a wave of his magic wand—turn you into a math lover.

2. Michelle Feynman — The Quotable Feynman & His Van

2. Michelle Feynman — The Quotable Feynman & His Van

Nobel Prize-winning physicist Richard P. Feynman (1918–88) was a towering scientific genius who could make himself understood by anyone and who became as famous for the wit and wisdom of his popular lectures and writings as for his fundamental contributions to science. The Quotable Feynman is a treasure-trove of this revered and beloved scientist’s most profound, provocative, humorous, and memorable quotations on a wide range of subjects edited by his daughter, Michelle Feynman, who will discuss her father’s life and legacy. In addition, physicist Seamus Blackey will bring Feynman’s van, newly restored and recently featured on The Big Bang Theory, so you can get your photograph taken with the famous vehicle featuring Feynman diagrams. Order The Quotable Feynman from Amazon. Our special guest at this salon will be: Dr. Leonard Mlodinow, physicist and author of Feynman’s Rainbow: A Search for Beauty in Physics and in Life and The Upright Thinkers: The Human Journey from Living in Trees to Understanding the Cosmos.

1. Dr. Lisa Randall — Dark Matter and the Dinosaurs: The Astounding Interconnectedness of the Universe

1. Dr. Lisa Randall — Dark Matter and the Dinosaurs: The Astounding Interconnectedness of the Universe

The renowned Harvard cosmologist and theoretical physicist explores a scenario in which a disk of dark matter—the elusive stuff in the universe that interacts through gravity like ordinary matter, but that doesn’t emit or absorb light—dislodged a comet from the Oort cloud that was ultimately responsible for the dinosaurs’ extinction. Dr. Lisa Randall teaches us an enormous amount about dark matter, our Universe, our galaxy, asteroids, and comets—and the process by which scientists explore new concepts.
