Gecko Tape

The tape is a simple version of the adhesive on a gecko’s feet. The soles of the lizard’s feet are covered with millions of tiny little hairs, too small to see with the naked eye. The molecules in these hairs snuggle up to the molecules of any surface the gecko walks on. The molecules are attracted to each other, forming a temporary bond that keeps the gecko firmly in place.

MIT Hosts Student Vehicle Design Summit

Solar concept car drawing

Student summit set on vehicle design by Deborah Halbe

Seventy-three students from 21 universities around the world will gather at MIT this summer to design and build between five and 10 commuter vehicles that exploit human power, biofuels, solar technologies and fuel cells to travel at least 500 miles per gallon of fuel.
…
An added goal for the June 13-Aug. 13 program is to lay a foundation for ongoing multidisciplinary transportation research involving all five MIT schools. “We hope to create a project-based, socially conscious engineering curriculum for the ’06-’07 academic year,” said Anna S. Jaffe, a junior in civil and environmental engineering and one of the summit student organizers.

Malaysia Looking to Learn from India

Lessons from India’s Success in IT Industry

Infosys alone has hired 300,000 fresh engineering graduates in the various disciplines so far this year and plans to take in another 140,000.

They will undergo a 14-month IT course designed to meet the current requirements of the relevant industries.

The numbers of new hires is amazing (update – see comments, in fact the numbers are not for Infosys. According to Bloomberg:

India’s biggest software makers, hired about 229,000 workers in India in the year to March 31, according to National Association of Software and Service Companies, or Nasscom. Tata Consultancy plans to add 30,500 jobs this year and Infosys 25,000, the companies said separately in April.).

Scientific Illiteracy

Scientific Illiteracy and the Partisan Takeover of Biology by Liza Gross, Public Library of Science:

Since 1979, the proportion of scientifically literate adults has doubled—to a paltry 17%. The rest are not savvy enough to understand the science section of The New York Times or other science media pitched at a similar level. As disgracefully low as the rate of adult scientific literacy in the United States may be, Miller found even lower rates in Canada, Europe, and Japan—a result he attributes primarily to lower university enrollments.

While the 17% figure does not amaze me I am surprised that the scientific literacy has doubled since 1979.

NSF Engineering Education Grants

NSF Engineering Education Grants:

Research is sought that contributes to our basic understanding of how students learn engineering. We are looking for significant breakthroughs in understanding so that our undergraduate and graduate engineering education can be transformed to meet the needs of the changing economy and society. We are interested in research that addresses: the aims and objectives of engineering education, the content and organization of the curriculum, how students learn problem solving, creativity and design, new methods for assessment and evaluation of how students learn engineering, and research that helps us understand how to attract a more talented and diverse student body to all levels of engineering study. It is expected that successful proposals will most likely be comprised of multidisciplinary teams of engineers and other fields that bring expertise pertinent to learning research.

The Full Proposal Target Date is 15 August 2006. View, recent proposals that have been funded, including: Integrating STEM Education Through Technological Design and Inquiry and Collaborative Research: Engineering Students for the 21st Century.

Lego Learning

Lego Mindstorms (via Amazon.com) are a great example of the learning opportunities available today. It seems true that the extracurricular learning options are much greater today than 50 years ago.

I Hear Rumors That Our Education Institutions Are In Trouble by Tom Hill:

We have living proof in my 60 short years that the education construction toy has progressed from the 20th century Erector SetÂ® to 21st century programmable LEGO Mindstormsâ„¢ robots.

We don’t have to worry about the future of education. Today’s youth will demand a superior local education system or they will go to any Internet institution that can satisfy their needs. All we have to do as the adults is make sure the local school systems and Internet institutions are capable of living up to our children’s expanding expectations.

I think the educational institutions may not be keeping pace with those advancements. But I agree that we need to see to it that those schools do keep pace with a changing world and changing expectations.

Two Butterfly Species Evolved Into Third

Two Butterfly Species Evolved Into Third, Study Finds by James Owen, National Geographic News:

Researchers say their creation reveals a process called hybrid speciation, in which the genes of two existing species combine to produce a third.

The study suggests hybridization may be more important to the evolution of new animals than had previously been thought.

Hybrids such as the mule, a cross between a donkey and a horse, are sterile. But the team says the butterfly hybrid brought together a combination of genes that allowed it to breed and there be considered a new species.

NSF Engineering Division is Reorganization

Read about the reorganization of NSF’s Engineering Division in their adobe acrobat (pdf) document (the only format in which they provide the document). How does an organization, in this day and age, post a scanned image online instead of posting a text readable document (for a present day document that obviously could just be printed to pdf format and retain text.

In addition to the obvious lameness of such a move when a federal government agency does it (like NSF) they violate the “section 508” regulations put in place to provide adequate access to government documents for those with disabilities.

Hopefully someone will get them to correct their failure soon. NSF does great things, but this failure to provide even the most basic web usability is an embarrassment.

Update – they did correct this, I don’t know when as it is months later when I am updating this but still I am glad they did.

Engineering Education: Can India overtake China?

Engineering education: Can India overtake China? by George Iype, Rediff:

India currently has 113 universities and 2,088 colleges, many of which teach various engineering disciplines. Engineering colleges in the country have been growing at 20 per cent a year, while business schools have grown at 60 per cent.
…
According to a McKinsey Global Institute study on the emerging global labour market, India produces a large number of engineering graduates every year, but multinationals find that just 25 per cent of them are employable. ‘In India, the overall quality of the educational system, apart from the top universities, could improve significantly,’ the report said.

Once again they quote the 600,000; 400,000 and 70,000 figures which the Duke University study shows is misleading. Still the short article provides some interesting information. Also the comment section shows the Duke study is beginning to seep into the public consciousness.

Examining the best numbers we can get (and trying to get better numbers to use for analysis) is a good idea. Still, we should not ignore the importance of the large macro trend. China and India are producing a significantly increasing proportion of the world’s engineers. Duke’s study indicate the comparison numbers are exaggerated, but the underlying trend is still strong and real.

I think the increase in China’s and India’s engineers will be a good thing for the world. And I think the both countries will continue to increase the numbers of engineers that are equal in skill and ability to others internationally (I can imagine today a higher percentage of USA engineers are highly skilled but that will not necessarily be true 30 years from now – it depends on the actions taken by many people, in government, academia and industry).

The continuation of the trend is not guaranteed; it will largely depend on the the continued economic success of India and China. If it continues it will also require some adjustments by engineers everywhere, which is one reason getting better data is wise.
