The annual Design Miami fair traditionally features an entry pavilion designed by early-career architects, a public installation that serves as a beacon for the fair and that provokes consideration and curiosity among the thousands of visitors who visit the fair's programs and galleries. For the 2015 pavilion design, Design Miami announced a first-of-its-kind collaboration with the Harvard Graduate School of Design.

Summer Science Exhibition 2016: Plastic not fantastic in our oceans

source: The Royal Society    2016年6月8日
It’s time to be drastic with plastic in our oceans.
Have you ever seen upsetting images of turtles, sea birds and fish tangled in plastic debris? The truth is that plastic is everywhere in the ocean, harming marine wildlife, and it will take extensive action to improve the situation.
This exhibit highlights the global plastic problem, and spotlights some of the high- and low-tech approaches to tackling it.
Our free, week-long festival (Monday 4 July - Sunday 10 July) features 22 curated exhibits and a series of inspiring talks and activities for all ages.

Bill Nye: Want to Combat Climate Change? Talk about It.

source: Big Think    2016年5月31日
Taking individual steps to affect the course of climate change is valuable, but collective action is more essential. To get there, we must talk about climate change, says Bill Nye the Science Guy.

Transcript - So people say to me Bill Nye, what can I do about climate change? And these days I acknowledge that not wasting water bottles, not throwing newspapers away, recycling, that’s all good and important. Driving less, driving smaller cars or more efficient cars, electric cars. But the main thing we can all do about climate change right now is talk about it. We just talk about climate change and raise awareness of it. Then the world’s biggest economy, the United States, might lead the world in addressing climate change, creating resources of renewable energy, wind and solar, most notably titled energy. Than we can export those technologies and change the world. So if I – since I believe that talking about it’s really important I talk about it all the time. And that’s – the more you think about it everybody – 97 percent of the world’s scientists – not 97 percent of some institute that somebody started in a remote part of the world and is making or releasing press releases. Ninety-seven percent of the scientists in the world are very concerned about climate change.

And you can look at the graphs. You can study the stuff for yourself. If nothing else do this. Wherever you live get access to the coldest temperature of each year for the last century. Unless you live in just very few places you will see the coldest temperature where you live is steadily increased. There’ll be some dips. There’ll be some ups but overall you’ll find it – and that’s just almost everybody who has Internet access can get those data that are available. And just look at that one thing and you’ll see the world’s getting warmer everybody. The ocean’s getting warmer so it’s getting bigger and those people are going to get displaced and we’re going to have to change our economy and where we do business. We’re going to be abandoning – heck there’s acres and acres of asphalt, roadways, copper plumbing. We’re going to be abandoning all that and it’s going to be expensive. So the sooner we get to work the better.

The Mahogany Staircase - Flutter's Layered Design

source: GoogleTechTalks    2016年5月5日
Google Tech Talk, 3/31/16, presented by Ian Hickson

ABSTRACT: Flutter is a new project to help developers build high-performance, high-fidelity, mobile apps for iOS and Android from a single codebase. Ian Hickson (Flutter's framework architect) will show why, knowing what we know now, we would design Flutter the way it is designed. Starting from an application that targets Flutter's low-level paint APIs, we will slowly move up the layers of abstraction reimplementing the application until we reach the material library layer.
This will not be a talk on "what is flutter" but rather "how and why is flutter built this way".

When it comes to what you bite, chew and swallow, your choices have a direct and long-lasting effect on the most powerful organ in your body: your brain. So which foods cause you to feel so tired after lunch? Or so restless at night? Mia Nacamulli takes you into the brain to find out.

Wayne Pacelle & Josh Tetrick: "Just Food" | Talks at Google

source: Talks at Google     2016年5月11日
Q&A featuring Josh Tetrick (Founder/CEO - Hampton Creek) and Wayne Pacelle (President/CEO, The Humane Society of the United States).
Josh Tetrick (Founder/CEO - Hampton Creek) and Wayne Pacelle (President/CEO, The Humane Society) discuss Wayne's latest book, The Humane Economy, as well as what rebuilding a food system could like from both an entrepreneurial and policy perspective.
Josh founded Hampton Creek in 2011 to make healthy, sustainable, and affordable food available for everyone. Josh was named one of Fortune Magazine's "40 Under 40" in 2015, and their flagship product, Just Mayo, was recently included in TIME Magazine's 100 New Scientific Discoveries (Fun fact: Google was one of the first companies globally to integrate Hampton Creek into their cafeteria food).
Wayne Pacelle has played a critical role in making The Humane Society of the United States (HSUS) a dynamic public force and voice for animals for more than 23 years, emphasizing the importance of state-level reform.

Queerness and Video Games: Identity, Community & Design

source: Stanford     2016年6月13日
From the Interactive Media & Games Seminar Series; Bonnie Ruberg, Provost's Postdoctoral Scholar in the Interactive Media and Games Division at the University of Southern California addresses how for decades LGBTQ people have been underrepresented in mainstream video games. Queerness in video games is more than a matter of who we see on-screen; it's also a matter of identity, community, and game systems. Thinking about games from the perspective of queerness offers us valuable lessons about design itself.
