Lethbridge Herald, The (Newspaper) - January 3, 1972, Lethbridge, Alberta 12 THI LETHMIDCE H1KALD Monday, January 3, 1V72 Your horoscope By Jeane Dixon TUESDAY, JAN. Your birthday today: The call of duty pervades your career effort for a long time to come, with a rather thor- ough revaluation and possibly weeping changes coming near the end of the year. To- days natives plan diligently, push their projects firmly and. quite often, harshly. ARIES (March 21 April Yesterday's flurry of activity continues, but do tilings your- Waves and particles Andy sends a complete 20- volume set of the World Book Encyclopedia to Tom Kirk, age 12, of Giradr, Ohio, for his question: How can liglit be waves and particles? This conundrum pops up ev- ery year, when students in school are introduced to the phenomenon of light. It seems that ordinary words fall flat on their faces when we try to use them to explain the wondrous mysteries of something we cannot sec. Certainly the words "wave" and "particle" fail to give a true picture of the nature of light. However, people continue to use these terms because they grew up gradually, as the mysteries of light were revealed. Light is a complex form of energy and only energy. It knows nothing of ocean waves or wavy hair-dos. In every oth- er realm of science, a particle is a small unit of matter. Since light is energy, it must be to- tally unrelated to particles of this sort. When studying light, perhaps we should stand waves and particles in a corner, far. ing the wall. In the light department, the word wave would be useful, if somebody hadn't sliced it in half. Actually it is an abbrevia- tion of wavelength, which rightfully belongs in the realm of energy. Wavelengths are the pulsing vibrations of speeding energy. They are unrelated to wavy seas and wavy hair, and to any other form of matter. Perhaps the term wavelengths arose because varying intensi- ties of pulsing vibrations re- minded somebody of up and down motions of the ocean waves. The length of a wave- length can be measured from one maximum intensity to the next somewhat like measur- ing ocean waves from crest to crest. The vibrations of light energy are measured in cycles or frequencies, which are so many pulses per second. Isaac Newton was the first person to suspect that light may be composed of miniature .bundles. He called them cor- puscles and did not refer to them as particles. That term arose during the century in which scientists disputed whether light is composed of wavelengths or miniscules bun- dles of some sort. The wave- length theory was settled in the 1860s, when James Clark Maxwell suggested that light is a form of electromagnetic en- with a rightful band on his electromagnetic spectrum. The so-called particle theory was settled in 1SCO, when Max Planck demonstrated that light travels in infinistesimal pack- ages of energy. He called them quanta and the energy of a quantum is related to wave- length. This settled the 100-yesr dispute as to whether light wavelengths or corpuscles. It is both. Light, as we know, travels in .straight lines at miles per second. Its quanta vibrate in transverse wavelengths at right angles to these straight lines. The quanta are units of energy. The are their vibrations. The band of visible light on Max well's electromagnetic spectrum includes a vast variety of wavelengths. Actual- ly it is a blend of longer and shprter wavelengths, traveling together at the same speed. The infinitesimal quanta vi- brate back and forth across the lines in. which the light is traveling.

The record is held by the 1913 naval debate when in successive weeks the chamber sat for almost days with- out a break. On Monday, March 3, 1913, the Commons started at 3 p.m. and sat right around the clock until midnight on Friday night, March 8, for a total of 129 hours. The following week it racked up 128 hours and 32 minutes, sitting from 3 p.m. Monday, March 11, until p.m. Friday, March 15. In this week's silting the 14 hours and 40 minutes of work- in? time was in a span of 16 hours and 40 minutes, with two hours off for dinner. On April 25-26, 19C7, the House devoted 15 hours and 10 miuntcs to business in a sit- ting that spanned 16 hours and 20 minutes.
