Home Experiments: Quantum Erasing

Do your own experiment on quantum erasing – Quantum Erasing in the Home (for instructions). From the accompanying article, A Do-It-Yourself Quantum Eraser:

The light patterns that you will see if you conduct the experiment successfully can be accounted for by considering the light to be a classical wave, with no quantum mechanics involved. So in that respect the experiment is a cheat and falls short of fully demonstrating the quantum nature of the effect.

Nevertheless, the individual photons that make up the light wave are indeed doing the full quantum dance with all its weirdness intact, although you could only truly prove that by sending the photons through the apparatus and detecting them one at a time. Such a procedure, unfortunately, remains beyond the average home experimenter.

Backyard Wildlife: Turtle

I took this photo in my back yard yesterday. It is the first time I have seen a turtle there. I saw a chipmunk today – I have see them occasionally but can’t get a photo of them – they move quite quickly ðŸ™‚ Other wildlife I have seen in my backyard: possum, raccoon, mole, fox, squirrels, rabbits, many birds including hawks and/or falcons, robins, starlings, doves, a humming bird once (front yard), butterflies, bats, lightning bugs, all sorts of bees, ants, praying mantis, and many more birds. And I see several cats prowl the yard frequently.

Funding for Science and Engineering Researchers

To authorize programs for support of the early career development of science and engineering researchers, and for support of graduate fellowships, and for other purposes. passed the house on a vote of 397 – 20 and was forwarded to the senate. From the majority whips talking points:

supports outstanding researchers in the early stages of their careers through grants at the National Science Foundation (NSF)
and the Department of Energy of $80,000 per year for 5 years
…
enlarges an existing program at NSF supporting graduate students in multidisciplinary fields of national importance

This bill started with the same name as the Sowing the Seeds Through Science and Engineering Research Act – though seems to be missing much on fellowships now.

Fruit Better Than Vitamins

Fruit proves better than vitamin C alone. Tests show that it isn’t just the vitamin that protects the body.

Other nutrition researchers have suggested that sugars in juice interact with vitamin C to generate the antioxidant effect2. But Guarnieri suspects that the phytochemicals found in oranges (cyanidin-3-glucoside, flavanones and carotenoids) are the substances that need further study. “But how they are interacting is still anyone’s guess,” she adds.

Innovation with Math

Flight Plan:

Invented by scientists at the nearby Los Alamos National Laboratory in the 1980s, complexity science is a gumbo of insights drawn from fields as diverse as biology, physics, and economics. At its core is the belief that any seemingly complex and utterly random system or phenomenon–from natural selection to the stock market–emerges from the simple behavior of thousands or millions of individuals. Using computer algorithms to stand in for those individual “agents,” scientists discovered they could build fantastically powerful and detailed models of these systems if only they could nail down the right set of rules.

When Brown arrived in town in the late 1990s, many of the scientists-in-residence at the Santa Fe Institute–the serene think tank dedicated to the contemplation of complexity–were rushing to commercialize their favorite research topics. The Prediction Co. was profitably gaming Wall Street by spotting and exploiting small pockets of predictability in capital flows. An outfit called Complexica was working on a simulator that could basically model the entire insurance industry, acting as a giant virtual brain to foresee the implications of any disaster. And the BiosGroup was perfecting agent-based models that today would fall under the heading of “artificial life.”

Eat Less Salt – Save Your Heart

Reducing salt cuts cardiovascular disease risk:

Cutting back on salt intake could lower the risk of developing heart disease by 25 per cent, in addition to lower blood pressure benefits, say researchers who studied people with borderline high blood pressure. Researchers in the U.S. looked at more than 3,000 people in two trials with pre-hypertension who reduced their sodium intake by 25 per cent to 35 per cent, compared with control groups that did not.

Cut Heart Risk by Eating Less Salt:

Last summer, the American Medical Association (AMA) called for a minimum 50% reduction in sodium in processed foods, fast foods, and non-fast-food restaurant meals within a decade. The group also called on the FDA to work harder to educate consumers about the health risks associated with a high-sodium diet.

“The average American is eating three times as much salt as is healthy every day — the equivalent of 2 to 3 teaspoons instead of no more than 1,” he says. “The assumption tends to be, ‘If I don’t use my salt shaker much, I’m probably OK,’ but that just isn’t true.”

10 Lessons of an MIT Education

Very good, definitely worth reading – 10 Lessons of an MIT Education by Gian-Carlo Rota:

In science and engineering, you can fool very little of the time. Most of the sweeping generalizations one hears about MIT undergraduates are too outrageous to be taken seriously. The claim that MIT students are naive, however, has struck me as being true, at least in a statistical sense.

Last year, for example, one of our mathematics majors, who had accepted a lucrative offer of employment from a Wall Street firm, telephoned to complain that the politics in his office was “like a soap opera.” More than a few MIT graduates are shocked by their first contact with the professional world after graduation. There is a wide gap between the realities of business, medicine, law, or applied enginering, for example, and the universe of scientific objectivity and theoretical constructs that is MIT.

An education in engineering and science is an education in intellectual honesty. Students cannot avoid learning to acknowledge whether or not they have really learned. Once they have taken their first quiz, all MIT undergraduates know dearly they will pay if they fool themselves into believing they know more than is the case.

On campus, they have been accustomed to people being blunt to a fault about their own limitations-or skills-and those of others. Unfortunately, this intellectual honesty is sometimes interpreted as naivete.

Toy and Entertainment Engineering Camp

via our post suggestion page, this Toy and Entertainment Engineering camp looks interesting (for students or a teacher) to me.

My name is Rebecca and I work for a Branded Camp Services. We design and operate residential academic summer camps for high school students.

This year, at Union College in Schenectady, we will be offering a course in Toy and Entertainment Engineering. I’m looking to hire an
energetic teacher for both two-week sessions in July. Most of our teachers are currently in graduate school or recent graduates. This
class is brand new and we’re having a harder time recruiting because of its specialized nature.

Thanks! You can apply by writing me at Rebecca at brandedcampservices.com

$600 Million for Basic Biomedical Research

Howard Hughes Medical Institute (HHMI) will hold a national competition for investigators that will result in an investment of at least $600 million in basic biomedical research. Up to 50 new researchers will be selected by spring 2008. HHMI Announces New Open Competition:

HHMI seeks applications from outstanding scientists studying biomedical problems in a broad array of disciplines, including not only biology and medicine, but related areas of chemistry, physics, engineering and computational biology. This competition is open to early career stage scientists at approximately 200 eligible institutions.
…
HHMI values innovation and encourages its investigators to extend the boundaries of science. By appointing scientists as Hughes investigators — rather than awarding research grants — HHMI is guided by the principle of “people, not projects.” HHMI investigators have the freedom to explore and, if necessary, to change direction in their research. Moreover, they have support to follow their ideas through to fruition — even if that process takes many years.
…
This new competition represents the first time that HHMI has opened up a general competition to the direct application process. In the past, faculty members had to be nominated by their institutions for HHMI investigator positions.
