Delving into the origin of mathematics

Image

When students at the Anna Science Centre-Planetarium were asked to fold a sheet of paper, little did they know the 16 folded squares were the starting point of a discussion on ancient mathematics and geometry.

More than 100 students delved into the world of mathematical origins in India in a session with archaeo-symbolist, Subash Chandra Bose, advisor, Cultural Research Centre, Coimbatore. The talk coincided with National Technology Day, observed to commemorate technological breakthroughs in India, including nuclear weapons technology. Incidentally, it was on this day, May 11,1998, that the Pokhran test was held.

While zero is hailed as India's significant contribution to mathematics, Mr.Subash chose to dwell on the number one, its associated symbols and its relationship with language and architecture.

The number one is symbolised by ‘plus' sign, which signifies addition.

The Tamil letter ‘ka' has evolved from this symbol, he observed through a series of diagrams. The symbol associated with number one was also instrumental in marking directions and giving rise to various shapes.

Mr.Bose also dewlt on the 16 square matrix, that he hailed as the fundamental of architectural constructions. The ‘swastika;' symbol was a derivative of the matrix, he noted.

He referred to the swastika shaped tank at Thiruvellarai as a rare structure, full of symbolism.

Students were intrigued on use of symbols in linear measurement.

Geometrical shapes hold inherent meanings, said Mr.Bose explaining while squares signify space, rectangles indicate dynamic energy and a cross causation.

“We are not responsible only for what we do, but also for what we fail to do,” concluded Mr.Bose, exhorting students to study and preserve native mathematical knowledge and ancient cultural symbols.

“A country that forgets its history and culture will forget itself. Not just what we are not doing."

Scientific experiments earn plaudits from students

Image

Concepts like theory of relativity and centrifugal force may go over the head on a hot summer afternoon for most school students. But at the summer camp at Anna Science-Centre Planetarium on Tuesday, 13 and 14-year olds hooted, cheered and heartily applauded the illustration of some conventional scientific principles.

Demystifying scientific concepts through simple demonstrations by Alagari Swamy, project director, Anna Science Centre-Planetarium was met with enthusiasm from close to 100 students who attended the first day of the three-day camp. A ball hovered in mid-air, sustained by air pressure from a blower with an intense drone. But when the end pipe was fitted with a funnel, the ball was sucked in. The simple experiment was an illustration of Bernoulli's principle, when pressure decreases with increase in velocity of a liquid. The concept was integral to flight of aeroplanes. A tug of war with a board for instance, explained increase in friction with increase in surface area.

In the opening session, P.S.Joseph, principal, Thanthai Hans Roever Arts and Science College, Perambalur, dwelt on various sciences like astronomy, electronics and mechanics. J.R.Pazhaniswami, senior scientific assistant, presented a scientific demonstration to illustrate fundamental principles like centre of gravity and conversion of energy. In the post lunch session, R.Victor Williams, head, Department of Physics, St.Joseph's College, introduced students to the world of robotics by assembling models of line robots. Origami, basic and observational astronomy, yoga and motivational science and a visit to the planetarium are in store for the next two days of the camp. With an opportunity to participate in the experiment, hands went up even before questions were framed though it was the final session of the day.

This type of curriculum is more needed for the kids, look at their faces

Enthusiasts rush to position for viewing mars opposition

Image

Children and adults alike swarmed around the Newtonian Reflector and the Celestron Refractor telescopes at Anna Science Centre Planetarium on Saturday, awaiting their turn to view mars opposition, a celestial event that occurs every 26 months.

An important event for mars observers all over the world, the opposition occurs when the mars, the first of the five superior planets (which lie outside the Earth's orbit) is at a point diametrically opposite to the Sun, when viewed from the earth.

When a planet is in this position, it's in a configuration that brings it closer to the earth. Being fully illuminated by the sun, it appears large as well as bright.

“Since the mars appears to rise during sunset and set during sunrise, it remains visible throughout the night, though the exact time of opposition is after midnight, around 1.40 am,” said S. Jaya Paul, scientific assistant, Anna Science Centre Planetarium.

Further explaining the phenomenon, he said the mars would be at a distance of 10.08 crore km from the earth during this opposition, and that it would appear big and red for a few weeks following March 4. “Earth-based telescopes can get the best views of the polar ice caps and dark markings that change with the planet's seasons,” he said.

“I am really excited about seeing the mars through the telescope and on Monday when I go back to school I would tell all my friends about what I saw at the planetarium,” said Abdul Razak, class IX, John Britto Matriculation School.

A number of parents who had brought their children to witness the opposition seemed as excited as the little ones. “On Friday, I noticed a bright red star on the sky and I checked with the planetarium about the star, and if they were organising a viewing,” said L. Supraja, mother of eight-year-old Neshaa.

I wanted my daughter to have a clear look at the opposition. The mars came closest to the earth during a previous opposition in 2003, when the distance between the two planets had shrunk to 5.5 crore km.

On an average, the mars and the earth are at a distance of 38 crore km from each other.

For the benefit of those gathered at the planetarium, the telescopic view of the opposition was displayed on a telescreen as well.

Sky observation programme

The Anna Science Centre–Planetarium here would organise a sky observation programme for the benefit of students and general public from 6.30 p.m. to 8.30 p.m. on March 3, in connection with the celestial phenomenon ‘mars opposition'.

The mars comes opposite to the sun once in 26 months due to the movement of the earth and the mars around the sun, and this event is called ‘mars opposition'.

This rare celestial event on Saturday is practically advantageous time to observe the mars, for it is in this configuration that the planet makes its closest approach to the earth and is fully illuminated by the sun, a release from the planetarium said on Friday.

Winter camp for students at planetarium

Inaugurating this year's winter student camp at the Anna Science Centre-Planetarium here on Thursday, S. Ruban Raj, head, Mathematics Department, St. Joseph's College, addressed over 90 students from the middle school level.

He touched upon the achievements of NASA's Kepler space telescope in identifying more than 700 exo planets. “The Habitable Exo planets Catalogue ranks the habitability of planets according to three criteria: their surface temperature, similarity to Earth, and capacity to sustain organisms at the bottom of the food chain,” he said.

The students, belonging to over 40 different schools, were briefed on Kepler's latest finding- a planet most earth-like in its size. The planet, which has been named Kepler 22-b is about 600 light years away from our solar system and orbits its own star in the zone that scientists term habitable. “Kepler 22-b, is about 2.4 times the size of Earth and lies in the so-called "Goldilocks zone".

It has a relatively comfortable surface temperature of about 22{+o}C (72{+o}F) though scientists are yet to determine its composition,” said Mr. Ruban Mr. Ruban also informed students about a rare event that 2012 would be witnessing. “The first of a pair of transits of the planet Venus (in the beginning of the 21{+s}{+t}century) has already taken place on June 8, 2004, and the next occurrence will be on June 6, 2012. After 2012, the subsequent transists of Venus have been calculated to occur in December, 2117 and December, 2125,” he said.

Counting four eclipses set to transpire in the coming year, he said the annual solar eclipse would occur on May 20, a partial lunar eclipse would occur on June 4. On November 13 and November 28 there would be a total solar eclipse and a penumbral lunar eclipse respectively.

Slated to take place over three days between December 29 and 31, the camp will see speakers from various colleges in the district, experts in yoga, electronics and origami.

Some of the topics that will be addressed include observational astronomy, history of mathematics, practical electronics, introduction to robotics, science and magic and origami among others. Also on the agenda are practical demonstrations of scientific experiments, a visit to the Planetarium's 3D Science Centre and a session on yoga and motivational science.

Spectacle keeps sky gazers spellbound

The total lunar eclipse, the last one of the year, presented a rare celestial event for the people of the central districts.

Exactly at 6.15 p.m. the full moon slowly started entering the shadow of the earth and at 7.35 p.m. the moon was totally inside umbra shadow.

The moon remained in the umbra shadow band till 8.28 p.m. Later the moon slowly started coming out, and at 9.48 p.m. it was totally out of the shadow and brightly lit moon was seen.

Naked eye

The lunar eclipse was well visible even with the naked eyes, said T. M. Alarigi Swamy Raju, Project Director (in-charge), Anna Science Centre – Planetarium here.

The Planetarium had made special arrangements for the viewing of the celestial spectacle for the benefit of the sky gazers. A large number of men, women and school and college students, viewed the event through the three telescopes – two celestron and one skywatch telescopes, which were placed at vantage points in the planetarium campus.

With the help of one celestron telescope people were able to view the Jupiter clearly. Other two were used for observing the moon and phenomena of eclipse. Through an audio video presentation on solar system Dr. Alagiri Swamy Raju, J. R. Palaniswamy, Senior Scientific Assistant, R. Akilan, Planetarium Engineer, S. Jayapal, Scientific Assistant, explained the lunar cycle and happening of the lunar eclipse to the visitors on the occasion. An Edusat camera was focussed towards the moon since evening. It was connected to the LCD projector, which projected the image of the moon as it is seen, minute after minute, on the giant screen much to the delight of the onlookers.
