How do we get from Wilbur and Orville Wright’s day where they could tinker their way to a major engineering breakthrough with little more than spruce frames, canvas and a hand built engine.... what.... "a hand built engine?" Where did this come from?
Math and young minds (3rd & 4th grades)
Submitted by Jim Myres on 28 June 2008 - 3:31pm. MathematicsIt might be hard for the young student to see the fun in math. Up till now it has been memorize, memorize, memorize for them. This can give them a break and tease their minds.

Quantum Physics; Humor, Sensationalizing, Hard Science, Espionage

Comics are supposed to be fun, light reading. Something I read on MSNBC’s Comics & Games website has been on my mind for a few months. The column titled "News of the Weird" by Chuck Shepherd (March 30, 2008) had one paragraph that caught my attention.
"A team of researchers from the University of Calgary and the Tokyo Institute of Technology proudly announced in February that they had successfully stored "nothing" inside a puff of gas and then had managed to retrieve that same "nothing." That "nothing," is called a "squeezed vacuum," and the physicists tell us that a light wave can be manipulated so that its phases are of uncertain amplitude, then the light itself removed so that only the "uncertainty" property of the wave remains.

A Theory of Knowledge
Submitted by Jim Myres on 13 April 2008 - 7:45pm. Philosophy & Ethics
Everything interacts with its environment - from the smallest sub-atomic particle to the largest galaxy. We are no different. Interaction insinuates dynamic inter-relationship. Knowledge can be defined as "post-active" comprehension. The dynamic inter-relationship involved in the comprehension necessary to achieve knowledge is the tension between opposites, or what may be called reciprocal reciprocation (RR). A RR consists of two diametrically opposing concepts which cannot exist without each other. They are mutually exclusive in concept and definition, yet mutually inclusive in the operation of comprehension. The opposition of the positive and the negative is the most readily recognized RR (ie. Yes and no). The simplest example is left and right. If something is left (yes) then it is not right (no) - and vice versa. A technological analogy of this would be the digital computer, where a circuit is either on (yes) or off (no). Two important facets of RR need to be under stood. First, one must remember that RR allows comprehension so that definition may be determined - at which time we acquire what is called knowledge. Thus even the slightest differentiation of objects or ideas is done through the use of RR: something just left of center will still be realized to be to the right of something - or, something we comprehend to be blue-green will be neither blue nor green, but something else.
Knowledge is Power
Submitted by Jim Myres on 1 April 2008 - 11:15pm. Science & SocietyA few weeks ago I wrote a blog about a Chicago charter school.
I was naive enough to believe that if a group of ninth graders could not read it was unique to this Chicago school. Today I read a report by Christopher B. Swanson, Ph.D. titled "Cities in Crisis: A Special Analytical Report on High School Graduation." Dr. Swanson’s report clearly shows that we are in an academic crisis in the U.S.
This report shows beyond a doubt America’s urban high schools are in a state of crisis. "Our analysis finds that graduating from high school in the America’s largest cities amounts, essentially, to a coin toss." In the most extreme cases, Baltimore, Cleveland, Detroit, and Indianapolis, fewer than 35 percent of students graduate. "The 50 most heavily populated cities in the U.S. were identified using 2006 data from the U.S. Census Bureau. These urban centers are widely distributed across the country, with top-50 cities scattered across 29 states."
Mathematical Mysticism

Trepanation: The Legacy Of Ancient Brain Surgery
Submitted by Jim Myres on 13 March 2008 - 9:42pm. Science HistoryIf you read the medical news lately you may have seen a headline title Skeleton May Show Ancient Brain Surgery. This article was about an 1800 year old skeleton found in Veria, Greece. The skeleton was of a woman of about 25 years of age that suffered severe head trauma and underwent cranial surgery, unfortunately evidence shows that she did not survive.
There is an interesting history of skull surgery, known as trepanation, which comes from the Greek word trypanon, meaning auger or borer. Cranial trepanation has caught the interest of surgeons and archeologist since the 1860's, when it was first realized that ancient humans had scraped or cut holes in the skulls of living persons in France and Peru.
Trepanation is serious enough surgical procedure in this day and age, could this procedure have taken place as a routine operation as long ago as 2000 BC? We do have a historical record of thousands of skulls with evidence of this surgery. Sometimes historical records suggest a reality that we find hard to accept.
Science & Math Education - Is Caring And Cash Enough To Make A Difference?
Submitted by Jim Myres on 9 March 2008 - 9:08pm. Science & SocietyI feel like I am going to be preaching-to-the-choir with this blog. The fact that you are reading it puts you in the "choir." I would encourage all of you to read the first two columns of the article "A New Bottom Line For School Science" by Jeffrey Mervis in Science Vol. 319, p. 1030-33, Feb. 22, 08.
The quote from this article that has me upset is "I don’t use a textbook or assign written homework because so many of them (the students) wouldn’t be able to read it." If this were a quote from a third grade teacher in a rural school for the children of migrant workers, I would still be upset but I could understand the teacher’s dilemma. How do I reconcile the fact that this quote is from a ninth grade teacher in a Chicago charter school, a school that specializes in math and science education?
How do we get to the point where an article in a prestigious science journal mentions the fact that a group of ninth graders in one of our largest cities can’t read and there isn’t a national outcry. The emphasis of the article is not about this school or this quote, it is about the $14 billion corporate philanthropy give away in the U.S. that targets pre-K - 12 activities in STEM (Science, Technology, Engineering, and Mathematics) education. Reading would appear to be a prerequisite for understanding math or science.
Dark Matter and Dark Energy

The Science and Technology Facilities Council has provided information that Science Daily has posted as an abstract of an article by Dr. Hong Sheng Zhao titled "Dark Fluid: Dark Matter And Dark Energy May Be Two Faces Of Same Coin." You can read this abstract at the web site below:
http://www.sciencedaily.com/releases/2008/01/080131094056.htm Dr Hong Sheng Zhao, of the University of St. Andrews, School of Physics and Astronomy, has shown that dark matter and its counterpart dark energy may be more closely related than was previously thought. "Both dark matter and dark energy could be two faces of the same coin." In Dr Zhao's model, dark energy and dark matter are simply different manifestations of the same thing, which he has labeled a 'dark fluid'. On the scale of galaxies, this dark fluid behaves like dark matter and on the scale of the Universe dark fluid behaves like dark energy. Only 4% of the universe is made of known material - the other 96% is "traditionally," (if seventy years can establish a ‘tradition’ in a three thousand-year-old science) considered dark matter and dark energy. Dr. Zhao’s model is detailed enough to produce the same 3:1 ratio of dark energy to dark matter as is predicted by cosmologists.
I would like to teach High School math when I retire, but we
Submitted by Jim Myres on 23 January 2008 - 10:05pm.I would like to teach High School math when I retire, but we will see. I went as far as to apply for and be accepted as a graduate student at Drexel University’s external degree program last year, but the cost is astronomical and I am well over sixty years old. This may not happen.
Antimatter Cloud
Submitted by Jim Myres on 22 January 2008 - 9:49pm. Aerospacehttp://www.sciencedaily.com/releases/2008/01/080109173722.htm
The above address is a post on Science Daily about an antimatter cloud. This should be of interest to the hard core science types and SiFi fans like myself.
The post describes an antimatter cloud that surrounds the galactic center. This cloud is about 10,000 light-years across. The European Space Agency’s "Integral" satellite has provided clues to the possible origin of this antimatter cloud. This post is well worth reading.
The author of this post quotes professor Marvin Leventhal, "I think I can hear a collective sigh of relief emanating from the (high-energy astrophysics) community." This may be so, but from the rest of us science hacks you are hearing a collective "What!" Apparently the "antimatter cloud was discovered in the 1970's by gamma-ray detectors flown on balloons."
