Lotto by the numbers

The pot for the Grandlotto 6/55 prize remained elusive as of last Monday’s draw. It has risen already to around P574 million last time and would likely breach 600 million. The large pot is a big payoff for the stream of bettors that line up the Lotto outlets everyday. Their dream is to get this prize for just P20 per combination.

Leonard Co: Naming the plants, planting the seeds

I would have written about the Lotto for this week’s column had not a text from a friend told me that leading botanist Leonard C. Co was reportedly killed in a supposed crossfire between the Armed Forces of the Philippines and the New People’s Army (NPA) in Leyte. They were doing research work for the Energy Development Corporation (EDC) in Upper Mahiao, Lim-ao, Kananga, in Leyte province with a security clearance when an Army patrol that responded to NPA sightings in the area chanced upon them.
Two other members of the EDC research team were reportedly killed together while two others survived.

In trying to figure out the significance of a single number, one would naturally try to appeal first to mathematics. For example, in mathematics, 43 is a prime number. Prime numbers are natural numbers (i.e. ordinary counting numbers) that can be divided only by itself and the number 1. Starting from 2, 43 is number 14 in the sequence of prime numbers. Of course, there would be other instances of the mathematical significance of 43 such as it being a Heegner number (which is a collection of numbers that is important in number theory) and the like. In base 6, it is a repeating digit number 111. Of course, outside of mathematics, the number 43 has other significance such as in chemistry where the element with the atomic number 43 is Technetium.

Teaching physics from first principles


Part 1

Around this time each year, the Samahang Pisika ng Pilipinas (SPP) meets for its annual physics convention and congress. The convention has been a forum for exchange of information and results of the leading edge in theoretical and experimental research of Filipino physicists and in the past few years with other physicists working abroad.

In investigating the characteristics of a certain system, one usually performs several measurements simultaneously on it to obtain an average description. Alternatively, one can observe the system for a certain period to find statistical and qualitative behavior patterns that do not change over time. If we have a-priori knowledge about the system’s dynamics, unexpected data points usually indicate the need to revise our original description. On the other hand, if the measurements match our a-priori description, it further validates it and makes it useful in forecasting future behavior.

Weather politics

The removal of Dr. Prisco Nilo as director of the Philippine Atmospheric, Geophysical and Astronomical Services Administration (Pagasa) due to “differences” with his “immediate superior” literally stirred up a storm last weekend.

Politicization of PAGASA will not solve its problems


August 7, 2010

The removal of Dr. Prisco Nilo as director of the PAGASA due to “differences” with his “immediate superior” shows that the current government would rather fire the messsenger than upgrade the bureau's capacity to prepare for typhoons and disasters.
