Math can prevent violence, says RP physicist

MANILA, Philippines–After the 9/11 attacks in the United States, I visited a Muslim vendor at the Greenhills Shopping Center tiangge. I asked her if she had experienced any repercussions, but she assured me: “We are fine. We are all friends here.”

For many years, Muslim and Christian stall owners have been engaged in friendly competition, as they ply their trade side by side.

At an international conference, I asked a Singapore educator how their country had managed to remain peaceful despite the variety of ethnic groups and religions there.

National Scientist Gelia Castillo

“EARLY in my working life i realized that I am not intellectually superior,” says National Scientist Gelia T. Castillo. “But as a simple sociologist, I found comfort in the thought that science must serve a human purpose. This often means doing science from the ground up and then tapping into sophisticated tools to address problems. When doing workshops in rice breeding, drought, trees, weeds, malaria, or HIV-AIDS, I always look for the people factor. For example, in breeding rice, I ask questions like: For what? For whom? For where? For what purpose? These are all people issues.”

I am proud to call Gelia a friend. Her story “The Eloquence of Seeds,” which shows her love for the natural world, is included in my book “Cogito Ergo Sum and Other Musings on Science,” which won a National Book Award.

Whatever Gelia may say, I affirm that she possesses not just intelligence, but wisdom as well. Take for instance, the fact that for scientists, progress is mainly counted by the number of journal publications; up to now, I still get a thrill when a paper has been accepted internationally. Gelia acknowledges this, but also adds, “Science pursued to address the problems of ordinary people often has other ways of communication than journals. When research fits into real life, the impact on human well-being makes it all worthwhile. Sometimes the proof of the pudding is in farmers’ fields.”

Queena Lee on math, music and movies

- Math, Queena Lee -

HERE’S an excerpt from Queena Lee-Chua’s latest column piece:

Randles often credits the Greek geometer Pythagoras for insisting on harmony in music. What role does Pythagoras play here? Recall the study of waves in basic physics. Those with the shortest wavelengths are for invisible light (such as X-rays, microwaves and ultraviolet rays), followed by relatively short color waves (such as the rainbow). Longer wavelengths are for sound waves.

According to Randles, the note “do” (from do re mi) has a particular frequency, measured in hertz. To ensure that music sounds good, the notes should follow a certain ratio, discovered by Pythagoras millennia ago. This ratio should be familiar to musicians: 1/1, 2/1, 3/2, 4/3, 5/4, 6/5, and so forth.
