Ice shells become strong and artful objects.

Ice shells become strong and artful objects.

When MIT students are out in freezing weather making things, anything can happen. During Independent Activities Period (IAP), they made structurally complex objects using the power of frozen water-soaked fabric. Watch the video Forces Frozen: Structures made from frozen fabrics.

The three-day workshop drew students from many disciplines.

The three-day workshop drew students from many disciplines.

The IAP workshop, titled Forces Frozen, pushed the boundaries of ice shells through design, experimentation, and fabrication. Led by Assistant Professor Caitlin Mueller ’07, SM ’14, PhD ’14 and post-doc Corentin Fivet, the workshop invited 30 students to research and design ice/fabric forms and the methods for making them on the first day and then spend the second day building formwork and rigging systems.  On the final day, they constructed an outdoor landscape of frozen structures and shared the work in a public exhibition.

The projects focus “on thin shell structures that get their strength not from the materials they are using or a thickness of material, but from the form they are using, just like an eggshell,” says Mueller. “The shells that we are designing are inspired by a twentieth-century Swiss structural designer, Heinz Isler…he was really inspired by nature and the forms that come out naturally through the forces of gravity. This is a really fun opportunity to combine physics, mechanics, and science with creating something that is almost artistic.”

Guest Post by Aaron Johnson from the Ask an Engineer series, published by MIT’s School of Engineering

Because bikers are tougher than meteorologists. Just kidding! Read on…

Phoro: Brent Moore

Turn on the news when a hurricane makes landfall and there’s a good chance you’ll see a brave (or foolish) meteorologist reporting live from the scene of the storm. He or she is probably yelling into the microphone about how the wind’s so strong that he or she has to hold onto a tree, traffic sign, or telephone pole to keep from blowing away. But attention-seeking meteorologists are not the only people who have to hang on during very high winds—motorcyclists are, too, every day. They’re also fully exposed, but they can zoom along at very high speeds and not fly off the back of their motorcycles? Why not?

It all comes down to a force called drag, says Richard Perdichizzi, a technical instructor in the Department of Aeronautics and Astronautics who operates the Wright Brothers Wind Tunnel.“Drag is the force a body produces as the air moves around it,” he explains. The amount of force is a function of two factors—the body’s cross-sectional area, and its shape. The cross-sectional area is simply the size of the object facing the wind. According to Perdichizzi, “the average person presents approximately eight square feet of blockage.” But that’s only if you’re standing perfectly upright. If you stand sideways and suck in your stomach, or if you roll up into a ball, your cross-sectional area decreases and you’ll experience less drag force. This is essentially what a lot of motorcyclists do when they’re zipping down the highway. They put their heads and shoulders down and pull their knees up, minimizing their cross-sectional area.

Motorcyclists need to be able to see and steer their bikes, so there’s a limit to how small they can make their cross-sectional areas. This is where the shape of the motorcycle becomes important. The fairing—the contoured piece of metal or plastic covering the front of the motorcycle—and the windshield are specially designed to be as aerodynamic as possible. They smoothly deflect the air instead of stopping it or creating turbulence like a flat, boxy surface would. Stopped and turbulent air lead to more drag. Read more

What’s one thing MIT students can do to increase their well-being this winter break? Sleep, according to Professor of Media Arts and Sciences, Affective Computing, Rosalind Picard SM ’86, ScD ’91. Picard is an instructor for MAS S63 Tools for Well Being, a course launched this past fall with a grant from the Robert Wood Johnson Foundation aimed at better understanding how individuals can be healthier and happier.

“The course is our way to start learning about our health,” explains Picard. She says providing a semester-long credit course is important for students who need to make their time commitments count.  “People are interested in so much,” she says. “At MIT you have so much you have to do, you often only do what you have to do rather than you want to do.”

Tools for Well Being—a Media Arts and Sciences course—offers weekly lectures from researchers and experts on a range of topics including diet and nutrition, mental health, workplace well-being, and cognitive health. Another benefit is that the Wednesday lectures, on topics ranging from How to Measure Stress, Engagement, and Positive Affect to the Science of Workplace Fitness, are open to the public.

Picard recommends sleep as a first-step to wellbeing.

Picard recommends sleep as a first-step to well-being.

“This is the whole picture of well-being. It’s like a resilience guide. If you are going to drive yourself to maximum performance, what do you need to know?” she says.

The course—open to graduate and undergraduate students—also focuses on technology as it relates to well-being. Some class speakers have experience building and using technology for well-being—like Kevin Slavin Assistant Professor of Media Arts and Sciences at the MIT Media Lab who previously worked in game development. The course culminates in a final project that requires students to design and prototype a tool for well-being. Past projects included a smart coupon model that would provide users with tailored coupons for healthy options and an app that assists in creating conversations to solve interpersonal conflicts at work.

Picard would like to see a smaller course focused on well-being as a requirement for undergrads, much like physical education is required.  She relates that though many courses may be interesting to students, taking courses outside of those required proves difficult for many.

“Students need to be as intelligent about their basic functioning as they are about bio and math. You must know how to take care of your own health so you can push yourself for four years and emerge strong and resilient,” she says.

A first step to increase that understanding is examining your sleep patterns, Picard says. As a recommendation to all students, the winter break is a great time to do this.

“Pay attention to how much sleep your body needs—that’s your natural rhythm. Figure out how to get closer to that when you get back to school,” she says.

Recorded lectures from Tools for Well Being are available to everyone.

Some people talk about cloud computing all the time, but they have their heads in the clouds if they think online information—web pages, music files, videos, and the vast seas of images and data—floats about magically in the ether, miraculously channeled through our laptops and smart phones. The Internet is not a magical cloud, explains Devavrat Shah, Jamieson Associate Professor in MIT’s Electrical Engineering and Computer Science department. It is a decidedly real collection of wires, optical fibres, electromagnetic waves, computers, and datacenters.

Understanding email is a good first step, Shah says. “A suitable analogy is the postal service. It uses an addressing system that enables a letter to be delivered to a specific place. The Internet does the same thing with emails. An email account is a specific unduplicated address.” There is, for example, only one askanengineer@mit.edu email address on the whole Internet.

When it comes to Facebook, Google, Netflix, or any other web destination, the situation is not so different. Facebook, for example, is a “virtual place,” Shah says, and its address is expressed as a URL, or a uniform (or universal) resource locator. When you type the URL of someone’s FB fan page, or your own page, into your web browser, the Internet takes you to that exact location – or, more accurately, it delivers that Facebook location to you by using a network directory service called the Domain Name System (DNS). Hosting more than a billion users, the Facebook you see on your computer actually lives on many servers in many different datacenters.

Last week six alumni working in space exploration as managers, engineers, and researchers joined us for Twitter chat MIT Alumni and the Final Frontier. The alumni fielded questions about their favorite projects, life at MIT, and shared insider knowledge on upcoming missions like OSIRIS-REx and Mars 2020.

New NASA Projects

All the alumni experts have a connection to NASA—as a current or past employee—and all have a great interest in upcoming missions, especially their favorites. Alessondra Springmann SM ’11 leaned towards asteroids, while Allen Chen ’00 SM ’02 had to pick an obvious favorite. Bobak Ferdowsi ‘03 chimed in with why he thinks the Europa Clipper mission is so exciting.

Mars 2020

The Mars 2020 mission will send another rover to the red planet—one with more capabilities than current rover Curiosity. Tamra Johnson ‘01 and Vanessa Thomas ’98 were curious how this newest mission might be different. Chen and Noah Warner ‘01, SM ‘03, PhD ‘07 shared some changes we can look for in 2020.

See You on Mars

Warner also shared insight into the future of the Curiosity—one we may never get to see.

Mission Moments

Caley Burke SM ’10 works in launches and Chen works in landings—both of which can be very stressful. Burke and Chen discussed what it’s like when they can finally breathe again.

NASA and MIT

Which AeroAstro class do the alumni keep thinking about? David Oh ’91, SM ’93, SCD ’97 joined in with his favorite.

To end the chat, Chen summed up what makes MIT and NASA so similar in his eyes.

This chat was cosponsored by MIT AeroAstro. See a more complete transcript of the chat
