The Bay Area is a hotbed of the "maker culture," and in the second hour of our special broadcast from the San Francisco Museum of Modern Art, we explore what's being made here -- and why. Public radio production team The Kitchen Sisters, Davia Nelson and Nikki Silva, take us through some of the highlights of their series "The Making Of...," a partnership with KQED Public Radio. The series profiles a variety of local creators: people making jam, creating opera, and even constructing the new Bay Bridge span. "The Making Of..." is also holding live demonstrations as part of the SFMOMA's free four-day celebration before the museum temporarily closes for expansion.

On June 3rd the San Francisco Museum of Modern Art will close its doors for nearly three years as part of a massive $610 million expansion project that will add a new wing, nearly doubling the museum's gallery space. Forum will bid farewell to the SFMOMA in its current state with a special broadcast from the museum's Schwab Room. We'll talk about plans for the museum's future, and the off-site programing SFMOMA will present at other museums and around the Bay Area during the temporary closure.

Are extroverts more persuasive than introverts? Does commission motivate good workplace performance?

The author and former speechwriter for Al Gore joins us to talk about his new book, "To Sell is Human: The Surprising Truth about Moving Others."

How does saliva work? Why doesn't your stomach digest itself? And did constipation really kill Elvis? In her new book "Gulp: Adventures on the Alimentary Canal," Mary Roach chronicles the surprisingly exciting journey that food undertakes in the human body. Roach joins us to talk about everything you ever wanted to know -- or might be disgusted to know -- about the digestive process.

Author and trend-spotter Douglas Rushkoff says humans are living in the present more than ever before. But he isn't talking about a serene Zen-like state of being in the moment. Instead, thanks to mobile devices and other technology, "presentism" is characterized by a constant state of distraction, and a need for immediacy which affects virtually everything: the way we tell stories, invest money, and even evaluate politicians. Rushkoff joins us to talk about his new book, "Present Shock.

War isn't what it used to be -- at least according to the conventional wisdom that modern warfare is now irregular and asymmetric, making traditional forces largely obsolete. But military historian Max Boot argues that guerrilla warfare and insurgency are hardly recent developments. Those tactics were actually common for most human history. In his new book, "Invisible Armies," Boot traces the history of irregular warfare.

California's new health insurance exchange took a crucial step this week, setting the rates that consumers will pay when the federal health care law takes effect on Jan. 1, 2014. Most say there isn't the rate shock that some had feared. But as we look ahead to further implementation of the Affordable Care Act, experts worry Californians will see spiking health costs, and that parts of the middle class will be left behind. Guests include: Glenn Melnick, professor and director of the Center for Health Financing, Policy and Management at USC; Jamie Court, president of the Consumer Watchdog in Los Angeles; and Lisa Aliferis, health editor for KQED News.

Recent news events such as this week's brutal killing of a British soldier in London, the Boston Marathon bombings, and the Congressional hearings on the Benghazi attacks have renewed a debate that has simmered since 9-11: What qualifies as terrorism?

In his 2001 graduation speech to medical students at Brown University, doctor and activist Paul Farmer said while science and technology are the heart of modern medicine, "you must add the soul." Farmer, the co-founder of Partners in Health, which brings modern health care to the poor, has focused much of his career on that hands-on approach to medicine, living among and treating locals in Haiti, Peru, Russia and other countries. Farmer joins us to talk about his advice to future doctors and his new book, "To Repair the World," a collection of his speeches on global health and social justice.

A New York judge fined an Airbnb user $2,400 this week for renting out a room in his apartment, arguing the three-night rental violated the city's "illegal hotel" laws. The popular San Francisco-based online site that allows users to offer their homes as temporary rentals has also been accused of disrupting local housing markets and failing to charge city taxes. Forum discusses what the ruling may mean for Airbnb and its users locally, and for other participants in the so-called share economy.

A U.S. Senate subcommittee this week accused Apple of exploiting loopholes and creating stateless foreign subsidiaries to avoid paying $9 billion in U.S. taxes last year. Yet the panel stopped short of alleging the company did anything illegal. We examine Apple's actions, the ethics of corporate tax dodging and whether the system should be reformed.

When photographer Bryant Austin came eye-to-eye with a humpback mother whale swimming with her calf, it changed his life. He decided he wanted to recreate that experience for others by making a life-sized print of a whale -- something that had never been done before. So he quit his job, sold his house, and flew to the South Pacific armed with only a snorkel and a camera. Bryant Austin joins us to talk about his book, "Beautiful Whale," and his secret to getting within three feet of the mammals, without them swimming away. We'll also talk to a marine biologist about the efforts to protect whales.

Los Angeles voters headed to the polls Tuesday to elect a new mayor. We talk about the race between L.A. City Councilman Eric Garcetti and City Controller Wendy Greuel, and what the outcome means for Los Angeles and the rest of the state.

NFL team owners voted Tuesday for San Francisco to be the official host of the 2016 Super Bowl. The event will be held at the San Francisco 49ers' soon-to-be constructed $1.2 billion facility in Santa Clara. We look at the economic and social impacts the event will have on the Bay Area.

San Francisco Giants relief pitcher Jeremy Affeldt is being called the most honest athlete in America, after he was overpaid half a million dollars and handed it back. He joins us in the studio to talk about his new book, "To Stir a Movement," his Christian faith, and his work against child slavery and child poverty.

In the suburbs of East Contra Costa County, the poverty rate has grown by more than 70 percent in the past decade. That's part of a Brookings Institution report chronicling the rise of suburban poverty nationwide. The report found the rate of poverty in suburbs has grown twice as fast as it has in the cities, but anti-poverty programs have been slow to respond and are still mostly focused in urban areas. We discuss the rise of poverty in the suburbs, and what can be done about it.

On Monday, troubled internet giant Yahoo announced it will purchase Tumblr, the social media and blogging network. We speak with the Silicon Valley journalist who broke the story about what Yahoo hopes to gain from the $1.1 billion acquisition, whether it can increase its appeal to younger audiences and the implications for Tumblr's loyal user base.

Journalist Jon Mooallem noticed that his young daughter was always surrounded by wild animals: butterflies on her pajamas, a stuffed toy owl, and beavers in her bedtime stories. But these romantic portrayals, he says, hid a harsh reality. Scientists estimate half of all species could be gone by the turn of the century. So he embarked on his own journey to track down three endangered animals, and discovered the extreme -- even futile -- lengths humans go to save them. Jon Mooallem discusses his book, "Wild Ones," and the complex intersections of man and nature.

A new edition of the most widely used psychiatric guide to mental disorders -- "The Diagnostic and Statistical Manual of Mental Disorders" -- was released this past weekend in San Francisco at a meeting of the American Psychiatric Association. The manual has a big impact on public health, including what insurance companies will cover, the drugs that regulators will approve, and even which children will receive special education services. But critics say that the manual is outdated and question the validity of several new diagnoses.
