“Queen of the Hurricanes,” World War II aeronautical engineer, Elsie MacGill, was the world’s first female aircraft designer. According to Wikipedia, having grown up encouraged by her mother to study engineering, she became the first women to achieve a long list of accomplishments. MacGill became the first female Canadian to earn an aeronautical engineering degree when she graduated in 1927 from the University of Toronto. Further pursuing aeronautical engineering, she was awarded a masters degree in this field from the University of Michigan, becoming the first woman in North America to have done so.

Starting her professional career, she became an Assistant Engineer at Montreal’s Fairchild Aircraft and then later became the Chief Aeronautical Engineer at Canada Car and Foundry, “the first woman in the world to hold such a position.” She was also elected as the first woman to be elected to membership in the Engineering Institute of Canada. MacGill designed and tested the aircraft, Maple Leaf II, as well as oversaw production of the Hawker Hurricane fighter aircraft, hence the reasoning of her nickname, “Queen of the Hurricanes.” On these fighter aircrafts, she also designed solutions so this aircraft could be operated in the winter time.

Elsie MacGill went on to start an aeronautical consulting business with her husband, E.J. Soulsby, and did much fighting for women’s rights in the 1960’s, all the while earning the title of ‘first woman’ to other accomplishments, including becoming the first woman to chair a UN committee. She lived from 1905-1980.

MacGill became so popular, a comic book was created about her.

Male Pipefish Behavior: A new NSF Funded Study show Male Pipefish give birth but some bond less with their offspring….

Female Pipefish (left) and Pregnant Male Pipefish (right)

Male Pipefish and Seahorses are the only male species able to get pregnant and give birth, but a new study conducted by Kim Paczolt and Adam Jones, researchers in the Department of Biological Science at Texas A&M University have found some fascinating links on how pipefish bond with their offspring during the postnatal period. The father who usually carries the embryos in a specialized sac during the prenatal period are quite nurturing but some fish alter their relationship with offspring after birth in accordance with their fondness for the mother.

The study looked at the reasons why some offspring flourish while others do not. Almost all the studies confirmed that the offspring who survived most often the male were fond of the female.  Showing an important link between the male’s mating choice and its offspring.

“The bottom line seems to be, if the male likes the mom, the kids are treated better,” Paczolt explains.

“Why this occurs, we don’t fully understand, but our findings are quite specific about this relationship between the male pipefish and its mate. If the male prefers the female, he treats their mutual offspring better.”

According to the National Engineers Week Foundation, the percentage of female engineering undergraduate students stands only at 20%. The number of women in the professional engineering workplace is less than that, at around ten percent.

In January, American Society for Engineering Education’s President, J.P. Mohsen, attended the Roundtable on Practical Approaches to Attracting and Retaining Women in Science, Technology, Engineering, and Mathematics {STEM} Fields, sponsored by the Society of Women Engineers. A main topic of discussion was the need of continual increases in the number of minority groups, especially women, in STEM. One point brought up in the discussion of why a female presence is so important in engineering is the fact that “Diverse perspectives lead to better solutions.” It is true that there is a lot being done to celebrate women {past and present} in these fields and to encourage younger females to become involved, however, there is still more to do.

Read Mohsen’s thoughts about this topic of diversity here, in the February 2010 edition of ASEE’s PRISM magazine.

There are many wonderful organizations and groups, conferences and competitions, programs and publications that celebrate and encourage women and young girls in what they are currently doing and in what they can do in the future in the world of engineering. In an attempt to shed more light on this topic, this Engineeringand… blog will be sharing stories of women who have made or are making significant impacts in the engineering and science world, as well as about organizations and programs that encourage and support females in science and engineering.


An Earthquake Proof San Francisco Bay Bridge

San Francisco Bay Bridge

San Francisco Bay Bridge

In the wake of the devastating 7.0 earthquake to hit Haiti this past week around the world television screens exploited images of crumbled buildings and poorly reinforced structures reminding us of another earthquake prone territory a little closer to home in California which is taking lengths to improve major infrastructure to a prominent landmark- The San Francisco Bay Bridge.

The Bay Area is known for its spectacular bridges,” says Bart Ney, a spokesman for the California Department of Transportation (Caltrans). “It’s part of our DNA, so naturally the aesthetics are a key part of the project.”

Caltrans ultimately decided to create a two-stage bridge, marrying a 1.3-mile Skyway to the first ever single-tower Self-Anchored Suspension (SAS) bridge. This revolutionary new structure hangs 1860 ft. of roadway from a single central tower, with the shorter western side rising from Yerba Buena Island, and the longer eastern side extending to meet with the Skyway.

The U.S. Geological Survey estimates there is a 62 percent chance that a magnitude 6.7 or larger quake will hit the area by 2032. The Bay Bridge is flanked on the west by the San Andreas Fault and on the east by the Hayward Fault — putting it right in the strike zone. Since the new bridge’s design specifications require that it last for 150 years, the engineers had to build in state-of-the-art seismic defenses. The SAS tower, for instance, incorporates deformable structural elements to absorb quake forces, much as a car’s crumple zone takes the brunt of a head-on collision. Thanks to this innovation, the structure should be able to accommodate seismically induced movement of up to 1 yard.


Science and Engineering Indicators 2010

The National Science Board’s Science and Engineering Indicators 2010 gives a comprehensive picture of the rise of developing nations in Asia, with China as the main engine, and gradual erosion of U.S. leadership. Examples:

  • North America’s share of world R&D activity between 1996 and 2007 dropped from 40% to 35% and the European Union’s share from 31% to 28%. The Asia-Pacific share increased from 24% to 31% “even with Japan’s comparatively low growth.”
  • American multinationals are shifting the R&D they conduct overseas from Europe to emerging Asian markets, whose share grew from 5% in 1995 to 14% in 2006.
  • China’s domestically earned natural science and engineering doctorates have shot up more than tenfold since the early 1990s, approaching the number awarded in the United States.
  • The share of U.S. engineering doctorates awarded to temporary and permanent visa holders rose from 51% in 1999 to 68% in 2007. Nearly three-fourths of these foreign Ph.D recipients were from East Asia or India.
  • From 1995 to 2008, the U.S. and E.U.’s combined share of world scholarly articles dropped from 69% to 59%, while Asia’s expanded from 14% to 23%. Over the past 20 years, the number of engineering research articles in the United States has grown by less than 2% annually. China’s engineering article output grew by close to 16% annually.
  • The share of patents granted to U.S.-based inventions by the U.S. Patent and Trademark Office is shrinking, from 55% in 1995 to 49% in 2008. In 1997, 34% of high-value patents had U.S. inventors; by 2006, this had slipped to 30%.

    Extreme Engineering: Luxury Cruiseship Setting Sail in 2010!

    Floating City

    Traveling the high seas has just gotten way better! The Oasis of the Seas ready to set sail in 2010 will undoubtedly be the largest cruise liner to date with a capacity to hold over 6,300 passengers over 2,000 more than today’s average passenger ship. The 18 story high luxury liner is a design engineering first with an outdoor park, the largest at sea swimming pool and the most rooms with balconies and decks.  To build such a ship of this caliber over 2,800 people were employed to construct the ship’s design.  The ship has three 20 foot tall propellers  mounted on swiveling pods along with electric motors that deliver the equivalent of 30,000 horsepower.

    “Ten years ago, we felt that 140,000 tons was as big as we could go,” says Oasis designer Harri Kulovaara. “Now that we’ve got the experience, we’ve taken a quantum leap.”

    The National Engineering Design Challengewhich promotes engineering by showing students ways engineers can solve social and community problems, is looking for sponsors. In the 2010 challenge, NEDC teams will put their creativity and problem-solving skills to use by designing and building an assisted technology device for a person in their community. Teams identify the problem they want to solve, work together to develop a solution and present their working prototype to an expert panel of judges.


    The Large Hadron Collider Comes Back with a BANG!

    The Large Hadron Collider is finally up and running again after months of repairs. The $8 billion dollar collider “accelerated the machine’s twin beams of protons to 1.18 trillion volts… that surpasses the previous collider record of 0.98 trillion electron volts, set in 2001 by America’s Tevatron collider.”

    An elite team of international physicists and engineers are continuing to make updates and repairs to the Large Hadron Collider in hopes of it reaching its full potential.

    The theory behind a collider is simple: Send a beam of protons crashing into something, either a stationary target or a beam of particles traveling in the opposite direction, then wait and see what comes out.

    As bigger and more powerful colliders were built, physicists began to uncover a plethora of tiny objects, such as quarks, which were held together by other tiny objects called gluons.

    To understand the infinitesimal nature of these new objects, consider that if a quark measured an inch, an atom would stretch a thousand miles.

    These discoveries allowed scientists to devise a picture of the universe at the subatomic level. Called the Standard Model, it is considered the most successful scientific theory in history, explaining how the melange of particles fits together and gives rise to the familiar forces that surround us.

    One thing the standard model has not been able to do, Mark Wise (a Caltech physicist) said, is show why particles have mass and how that mass is distributed.

    Scientists believe that’s because the particle responsible for mass, the Higgs boson — named for Scottish physicist Peter Higgs — can’t be produced in today’s accelerators. Because it is thought to bind weakly with other particles, “you need a lot of collisions” to produce one, Wise said.

    The Large Hadron Collider is located in a 17-mile circular tunnel 300 feet underground on the Franco-Swiss border. Scientists expect to surpass their recent record of accelerating to 1.18 trillion electron volts within the coming months.


    Undergraduate Researchers Win Big at “Energy Challenge” With New Turbine Converter

    International Future Energy Challenge winners, Jonathan Baker and Christopher Hamilton created a low-cost wind turbine that transfers a maximum amount of energy to a battery. How did they do it? They contribute their success to time spent doing undergraduate research.

    Baker, Hamilton, and two fellow electrical engineering majors spent over a year preparing their “low-cost wind turbine energy maximizer” for the International Future Energy Challenge in Australia last July.

    The two-some invented a three-phase AC/DC converter (also known as “The Pegador” to its creators) to make the energy produced by wind turbines more efficient. The Pegador took home first prize.

    After enjoying the success of placing first, Baker and Hamilton garnered success among engineering peers from universities worldwide.

    Their participation in undergraduate research is what they claim to be the ultimate stepping-stone for future success within the scientific community and public-at-large.

    “Going from book knowledge to tangibility experience has really accelerated my future career,” Baker said. “I’ve graduated with not only an honors degree, but an actual invention and experience.”

    “Today’s engineering students want to make difference in the world … they want to make the world a better place through technological innovations that save lives and help clear the environment.” – Issa Batarseh, professor and director of the School of Electrical Engineering and Computer Science. Batarseh also oversaw the project.

    There is no release date for the turbine at this time.
