Engineers: Future Prospects

In the The Future is Engineering I discussed some of the benefits of engineering education. And previous posts shows that S&P 500 CEOs are more likely to be engineering graduates than any other discipline. The future of engineering looks at what is in store for students of engineering today:

I doubt many of the incoming freshmen at Lehigh who are about to enter the College of Engineering have any clue what they are getting themselves into. I suspect they will end up very pleased with their choice… especially when they realize large numbers of engineering graduates before them did not take jobs as engineers but instead were hired as consultants – as a result many graduates are paid much higher salaries than they would have dreamt of as freshmen.
…
But are they waging a rearguard battle, will the US become a services-land where most of the real engineering is outsourced to countries that value science more, and where the so-called engineers are number-crunching problem-solvers who stare at computers all day long? Or will the pendulum swing back in the engineers’ favor after a Sputnik-like incident that will bring engineering back into the list of national priorities?

It is very important to remember that the benefits of studying engineering cannot be measured solely by looking at engineers in the workplace – many go into different job title and are promoted into management… and as stated above CEOs. The second point will be an important determinant of the economic strength of the USA as I have addressed many times I think it is important the USA maintain science and engineering expertise. The multiple benefits of having research centers here, manufacturing engineering expertise… is huge. See: Continue reading →

Mistakes in Experimental Design and Interpretation

Mistakes in Experimental Design and Interpretation:

Humans are very good at detecting patterns, but rather poor at detecting randomness. We expect random incidents of cancer to be spread homogeneously, when in fact true randomness results in random clusters, not homogeneity. It is a mistake for an experiment to consider a pool of 47,000 possibilities, and then only report on the 7 cases that seem interesting.
…
A proper experiment states its hypothesis before gathering evidence and then puts the hypothesis to the test. Remember when you did your seventh grade science fair experiment: you made up a hypothesis first (“Hamsters will get fatter from eating Lucky Charms than Wheaties”) and then did the experiment to confirm or refute the hypothesis. You can’t just make up a hypothesis after the fact to fit the data.

This is an excellent article discussing very common errors in how people use data. We have tendencies that lead us to draw faulty conclusions from data. Given that it is important to understand what common mistakes are made to help us counter the natural tendencies.

EasyJet EcoJet

The easyJet ecoJet: to cut CO2 emissions by 50% by 2015:

Rear-mounted “open-rotor” engines offer unrivalled environmental performance for short-haul flying due to their higher propulsive efficiency. However, there are significant difficulties in fixing such a large engine under a wing of a narrow-body aircraft, making rear-mounting of the engines the optimum solution.
…
In addition to engine efficiency and weight reduction, one of the primary methods of reducing fuel burn is by reducing drag. Conventional jet aircraft currently suffer increased drag from turbulent airflow over their wings. A wing profile that allows the easyJet ecoJet to maintain laminar flow over a significant proportion of the wing will greatly reduce cruise drag.

Giving the wing a slight forward sweep increases the proportion of laminar flow over the wing (as the clean airflow from the wingtip tends to flow to the wing root in contrast to the turbulent air from the fuselage being dragged across the wing with conventional reverse sweep). In addition, it improves the stall performance of a laminar flow wing. Minimising drag is imperative in the design of glides and most gliders with laminar flow wings also have a slight forward sweep to the wing.

Scanning Electron Microscope Rose Art

Rose Petal Installation Inspired by Science:

Carnegie Mellon University School of Art senior Lisa Huyett has created a large-scale installation titled “S.E.M. Rose” (Scanning Electron Microscope Rose), a re-creation of the surface of a rose petal, at the Children’s Museum of Pittsburgh. The artist rendered the magnified image of a rose petal using a scanning electron microscope while a student in the university’s interdisciplinary Art and Biology course.
…
Scanning electron microscopy uses a beam of electrons to reveal the nanostructures of material surfaces at up to one million times their normal size. Under the guidance of Joseph Suhan, electron microscopist at the Electron Microscope Facility in the university’s Mellon College of Science, Huyett magnified a rose petal 500 times, revealing bristly, knob-like structures that make up the velvety appearance of the petal.

Universities allowing students to be inspired by science is great. While creating scientists and engineers is important it is also important to let students studying other area to engage with science. I also enjoy the art inspired by science, including previous posts: Art of Science 2006 – Get Your Own Science Art – Art of Science at Princeton

Scientific Review

This is the way science should always work:

Here’s the short version. Dr. Hall made a mistake in the software he wrote to do something. Another scientist, Dr. Otto, saw the mistake, contacted Dr. Hall and told him about it, and the two of them worked together to confirm that it was in fact a mistake. Recognizing the error, Dr. Hall has now retracted the paper and is working to ensure that people quickly learn that the conclusions are in error. Knowing that will keep others from using Dr. Hall’s original conclusions in their own work, which means that they won’t be starting from a position that’s wrong.

And that, ladies and gents, is exactly how this thing called “science” is supposed to work.

Great post. Interesting comments too. It is not any easier for scientists (than anyone else) to admit mistakes, but scientists view advancing scientific thought as the most important factor. By exposing papers to colleagues the community’s collective effort is brought to bear on finding any weaknesses and to building on the new knowledge to advance scientific understanding further.

River Blindness Worm Develops Resistance to Drugs

River blindness resistance fears

Resistance could lead to breakouts of the infection in communities where it has been brought under control, a Canadian study in the Lancet reports. Ivermectin, used since the late 1980s, is the only drug available for the mass treatment of river blindness. Experts warned the findings highlighted the urgent need for new treatments. River blindness (onchocerciasis) is caused by a nematode worm which is transmitted by a black fly.
…
He added that isolated resistance could be controlled by using insecticides or an antibiotic called doxycycline, which is effective but needs to be given every day for a long time.
…
Professor Taylor’s team have recently received a large grant from the Bill and Melinda Gates Foundation to search for new drugs or combinations that can have the same effect as a course of doxycycline but delivered in shorter time frame.

The Bill and Melinda Gates Foundation is funding a tremendous amount of important work.

Goldwater Science Scholarships

I have mentioned previously, I work for ASEE (the curious cat blog is not associated with ASEE). At ASEE, we have started a science and engineering fellowship blog. The latest post covers the Goldwater Science Scholarships – for undergraduate students in science and math. Approximately 300 are awarded each year.

For 2007, 28 mathematics majors, 223 science and related majors, 54 engineering majors, and 12 computer science majors received awards (many of the Scholars have dual majors in a variety of mathematics, science, engineering, and computer disciplines). The one and two year scholarships will cover the cost of tuition, fees, books, and room and board up to a maximum of $7,500 per year.

The Goldwater Foundation is a federally endowed agency established by Public Law 99-661 on November 14, 1986. The Scholarship Program honoring Senator Barry M. Goldwater was designed to foster and encourage outstanding students to pursue careers in the fields of mathematics, the natural sciences, and engineering. Applications will be available starting in September for next year. Schools nominate up to 4 students for the scholarship, see the web site for details on the application process.

Education, Entrepreneurship and Immigration

Education, Entrepreneurship and Immigration: America’s New Immigrant Entrepreneurs is part 2 of a study by Duke’s Pratt School of Engineering and UC Berkeley. Some interesting points from the study:

52 percent of immigrant founders initially came to the United States primarily for higher education, 40 percent entered the country because of a job opportunity, 6 percent came for family reasons, and only 2 percent to start a business.
91 percent of Indian founders, 35 percent of Chinese and 97 percent of Taiwanese founders completed their undergraduate degrees in their home country
Indian and Chinese founders graduated from a diverse set of schools in their native countries, many of which are considered
second- or third-tier universities (only 15 percent of Indian founders were graduates of the IIT).
Immigrant founders of technology and engineering firms have strong backgrounds in science, technology, engineering, and mathematics (STEM) fields. 75 percent had completed their highest degree in a STEM field.
Advanced education in science, technology, engineering, and mathematics is correlated with high rates of entrepreneurship and innovation. The U.S. economy depends upon these high rates of entrepreneurship and innovation to maintain its global edge.

High Resolution Darwin Documents

View high resolution scans of Darwin’s notes and review his thoughts and ideas. Speaking of Faith (American Public Media program) has teamed with Cambridge University Library to present a narrated tour of Darwin’s private notebooks and hand sketches with David Kohn.

Very interesting. I am not thrilled with the usability of the web application but the high resolution images are interesting and the narration is informative.
