This is your brain on equality

Thursday, February 25th, 2010

It seems the human brain is pre-wired to react strongly to inequality. I was just thinking that ants and bees have highly stratified social structures that are quite different in terms of responsibility and danger. I wonder, if humans didn’t have this brain circuitry, would we have ever claimed a universal distribution of inalienable rights to life, liberty and the pursuit of happiness?

Scientists have recently discovered that running without shoes is far easier than most people think. Not only that, it’s far less likely to cause injuries and physical stress than running with shoes. Amazing! It’s almost as if we evolved from ancestors who didn’t have Prada or Nike…

Human Search Filters and the Wisdom of Science

Wednesday, January 3rd, 2007

The Internet is an impartial tool with which we can support our delusions of reality, or conversely build an objective and valid world-view.  The tendency is toward the former, it takes intention and education to pursue the latter course…

I’ve been reading “The Varieties of Scientific Experience” by the late Carl Sagan. I love Sagan’s publicly available writings, and I agree whole-heartedly with every bit of his thinking I’ve come across regarding skepticism, reason, agnosticism, scientific investigation and his recommendations for social agendas. In fact, I agree so vehemently that I wonder why I should bother reading his book. It is essentially mental masturbation; an opportunity for pounding my fist, clapping my hands and exclaiming “YEAH!!”. From my personal perspective the book is mostly bereft of new material which might persuade or inform me. But I love Carl, and the book contains some interesting anecdotes which were otherwise unknown to me. I find myself feeling guilty about “wasting time” while reading it though, since it does not really move my mind into new territory.

I often attend meetings of the Kendall County Democrats, where I am able to join folks with some similar opinions about politics, policy and candidates. So far, we have never discussed policy, theory, position or strategy. In any case, there has never been any debate which challenges me, or causes me to question my preexisting conclusions. Again, I wonder if the benefit of my attendance is limited due to the homogeneity of the experience.

My favorite websites include those which convey information about current scientific discoveries, pragmatic and rational political theory, scientifically-augmented positions on economic and social policy and environmentally sustainable conservation. I never visit sites with active dialogues about the Christian Rapture, anti-abortion, theories of politics or policy viewed as divinely sanctioned, anti-minority rants, those with unscientifically supportable contentions about global warming or the environment, theories regarding mystical “energy”, homeopathy, pseudoscience, or any of a million other perspective which are anathema to my personal preference for pragmatic, scientific and compassionate philosophies of life. I like learning new things and discovering alternative perspectives, but a vast number of my fundamental views are never likely to change – and I don’t seek to do so.

The Internet is a fantastic tool for finding information. One can find an arbitrarily large amount of argumentation, “data”, pithy quotes, personal claims and opinions and passionately held positions on pretty much anything one wishes to investigate. Certainly a similar statement can be made regarding other media – whether print, television, radio or special-interest clubs; but the Internet brings the largest quantity of information, it brings it for a trivially low price, and it can bring it to you in private.

The Beef with Beef

Friday, December 29th, 2006

The recent ruling by the FDA specifying that warning labels are not required on cloned beef has caused angst among some people who don’t understand the process or results of cloning. 

When a plant or animal cell reproduces, a process called “mitosis“, elaborate bio- and micro-chemical processes occur which (far more often than not) lead to the double-helix of the original DNA splitting into two identical halves.  These halves, as they are being ”unzipped” from the helix, are each copied perfectly by enzymes in the cell body.  The result is two flawless copies of the original DNA double helix molecule - each containing half of the original DNA molecule.  Other intracellular “machinery” then facilitates the splitting of remaining cellular components, including the “energy factory” mitochondrea organelles and eventually the “goop” (cytoplasm) in which cellular structures and molecules swim and the cell boundary itself.  When all components have been duplicated and/or split apart, the result is two identical cells.
