• We so-called experts have been wrong for almost 7 years

  By ljd42 on October 30, 2005

  Those of us who teach math and computer science have been proud of our knowledge that a kilobyte is really 1024 bytes, not 1000. So “Y2K” doesn’t really refer to 2000 but to 2048. Similarly, we believe (and teach) that… Read More ›

• Pythagorean Theorem in so-called real life

  By ljd42 on October 29, 2005

  Reading this case might prove helpful for some students who think that math is useless in real life (at least those who plan to be lawyers or drug dealers). But shouldn’t the court have used Taxicab Geometry for its distance… Read More ›

• Irrationality considered harmful

  By ljd42 on October 28, 2005

  “I refuse to deal with irrational numbers until they’ve calmed down,” says one Jeff Schult, who claims that math is a cult. Read the whole article. I hope it doesn’t represent what Weston students think about math. We shouldn’t use… Read More ›

• Should honors classes be open to all?

  By ljd42 on October 27, 2005

• Charging what the market will bear

  By ljd42 on October 17, 2005

  The folks at TechFusion must be good guys, right? After all, their company is one of WBUR’s underwriters. And they advertise “No Job Too Large or Too Small.” Of course I was suspicious in the first place when I heard… Read More ›

• Globe speaks out for Dorchester!

  By ljd42 on October 11, 2005

• The power of visual representations

  By ljd42 on October 10, 2005

• Anti-Semitism?

  By ljd42 on October 9, 2005

• Hacking, not cracking

  By ljd42 on October 8, 2005

  By ljd42 on October 6, 2005

  By ljd42 on October 6, 2005

• Conspiracy theories

  By ljd42 on October 5, 2005

  From the right: THE HILLARY CLINTON ’08 CAMPAIGN AIRED ITS FIRST, HOUR-LONG COMMERCIAL last night.

• Robert Noyce and Bringing Down the House

  By ljd42 on October 2, 2005

• Merit pay

  By ljd42 on September 30, 2005

• Back-to-school night

  By ljd42 on September 29, 2005
