  • Institutional Racism Spike Lee
    595 words
    Anyone who would dismiss Spike Lee as a racist is confusing pride with prejudice. Sure, hes abrasive, blunt, unvarnished and maybe egotistical. But hes also got the self-confidence, fearlessness and knowledge of his personal mission that in past years, and some parts of Idaho today, would have gotten him called an uppity N-word, maybe worse. This reaction to him, to him in America today, and on our campus this week, is an illustration of how far whites (yes, whites) in this nation have not come....

  • Sharks And Rays Electric Fields Signal
    257 words
    Nearly forty years ago, I observed sharks and rays respond to weak electric fields. The biological significance of this finding became evident when shortly thereafter I discovered the common bio electric fields in the vicinity of aquatic animals. The electric sense became an established fact when I proved that sharks and rays cue in on the electric fields of prey, even during the dark or when the prey is hiding in the sand. Field strengths as low as 1 - 2 nV/cm suffice to alert them as to the pr...
