Space Shuttle Against the Sun

Into the Sun

Space Shuttle against the sun
Just thought I’d share a couple of super-cool image of the Space Shuttle silhouetted against the sun on its way to service to the Hubble Space Telescope. The fist image shows a clear shot of the Shuttle silhouetted against the sun, and the second image shows the Shuttle (the larger black dot) as it approaches the Hubble Space Telescope (the smaller black dot). Pretty cool!

Can’t wait to see new images from deep(er) space from the upgrades performed on the space telescope by the Shuttle crew.

Images captured by award winning French astro-photographer Thierry Legault.

Patients Sought for Scientific Marijuana Study

Karen O’Keefe, Marijuana Policy Project (MPP) assistant director of state policies:

There is good reason to believe that marijuana can boost the efficacy of opioid pain drugs, allowing pain patients to get better relief with smaller doses of narcotic medications. University of California, San Francisco researcher Dr. Donald Abrams is looking for participants to take part in an important pilot study that could lay the groundwork for critical research in this area.

Dr. Abrams is conducting a trial of vaporized medical marijuana in conjunction with opioid medications in chronic pain patients. This is an opportunity for patients to try controlled doses of medical marijuana completely legally — under both state and federal law — for five days and for researchers to collect important data about the safety of medical marijuana.

The study will assess the clinical safety of using marijuana with opioids by monitoring the short-term side effects associated with combined therapy.

Participants in the study must:

  • Have ongoing chronic pain
  • Be 18 or older
  • Be on a stable twice-daily dose of sustained-release oxycodone or morphine medication for at least two weeks before enrollment
  • Not use marijuana for a month prior to entering the study
  • Not be a cigarette and/or cigar smoker, or be willing not to smoke for two weeks before starting the study
  • Meet some additional criteria

Participating patients will:

  • Spend five days and nights in a clinical research center at San Francisco General Hospital
  • Attend a screening appointment before the study begins
  • Have blood tests and other measurements done
  • Inhale vaporized medicinal marijuana three times a day

You can receive $520 for participating. For more information, call (415) 476-9554, ext. 315, or e-mail . The Community Consortium Positive Health Program of the UCSF Medical Service at San Francisco General Hospital is conducting the study.

Thank you for supporting the Marijuana Policy Project. Please pass this on to any chronic pain patients who might be interested in participating in the study.

The Marijuana Policy Project hopes that each of the 100,000 subscribers on our national e-mail list will make at least one financial donation to MPP’s work in 2007. Please visit to donate now.

MPP will be able to tackle all of the projects in its 2007 strategic plan if you and other allies are generous enough to fund our work.

We are required by federal law to tell you that any donations you make to MPP may be used for political purposes, such as supporting or opposing candidates for federal office.

The Loud, Proud, Ignorant, Incompetent

You might find the following study fascinating. It explains a lot. I found it out of the blue on the Wikipedia.

Dunning-Kruger Effect

The Dunning-Kruger effect is the phenomenon whereby people who have little knowledge systematically think that they know more than others who have much more knowledge.

The phenomenon was demonstrated in a series of experiments performed by Justin Kruger and David Dunning, then both of Cornell University. Their results were published in the Journal of Personality and Social Psychology in December 1999.

Kruger and Dunning noted a number of previous studies which tend to suggest that in skills as diverse as reading comprehension, operating a motor vehicle, and playing chess or tennis, that “ignorance more frequently begets confidence than does knowledge” (as Charles Darwin put it). They hypothesized that with a typical skill which humans may possess in greater or lesser degree:

  1. incompetent individuals tend to overestimate their own level of skill,
  2. incompetent individuals fail to recognize genuine skill in others,
  3. incompetent individuals fail to recognize the extremity of their inadequacy,
  4. if they can be trained to substantially improve their own skill level, these individuals can recognize and acknowledge their own previous lack of skill.

They set out to test these hypotheses on human subjects consisting of Cornell undergraduates who were registered in various psychology courses.

In a series of studies, Kruger and Dunning examined self-assessment of logical reasoning skills, grammatical skills and humor. After being shown their test score, the subjects were again asked to estimate their own rank whereupon the competent group accurately estimated their rank, while the incompetent group still overestimated their own rank. As Dunning and Kruger noted:

Across 4 studies, participants scoring in the bottom quartile on tests of humor, grammar, and logic grossly overestimated their test performance and ability. Although test scores put them in the 12th percentile, they estimated themselves to be in the 62nd.

Dunning and Kruger

Meanwhile, people with true knowledge tended to underestimate their competence.

A followup study suggests that grossly incompetent students improve both their skill level and their ability to estimate their class rank only after extensive tutoring in the skills they had previously lacked.

Cosmic Event: Venus & Pleiades Converge

Venus and Pleiades converge in night sky

Venus and the Pleiades are converging for a
close encounter on Wednesday, April 11th.

At closest approach, the planet and the star cluster will be about 2 degrees apart, tight enough to fit behind your upturned thumb held at arm’s length. They’re an odd couple. Venus is extravagantly bright while the Pleiades are faint and delicate, yet together they make a pretty ensemble suitable for photography, binoculars or simple naked-eye viewing.

Watch the western sky after sunset in the nights ahead to see them drawing together.
