GENIUS MEET 2010 -Eduworld

Thiruvananthapuram (14 August 2010)

Eduworld Foundation – A non profit organization aimed at nurturing scientific spirit in children organized Genius Meet 2010 for the students of Trivandrum schools who scored high in class 10 during the year 2010. About 150 students along with their parents participated.

Former chairman of the Indian Space Research Organisation, G. Madhavan Nair interacted with the students.

The participants also got chance to hear and interact with Sh. B.N. Suresh, Director of the Indian Institute of Space Science and Technology; Dr. E.D. Jemmis, Director of the Indian Institute of Science Education and Research; A. Sivathanu Pillai, Chief Executive Officer of BrahMos Aerospace.

Dr. Sivathanu Pillai’s address and presentation were very much appreciated by the audience. All were wonderstruck with the advancement and the high degree of precision India has achieved in the field of missile technology.

The students were taken to a visit to the Science and Technology museum and in the mean time Prof E D Jemmis interacted with the parents of the genius students and stressed on giving freedom for the students to think and choose the right career which they find themselves suitable for. He stressed on the importance of attending the exams like KVPY (Kishore Vygyanik Protsahan Yojana – A scheme introduced by the Govt of India to identify the genius and to grant them scholarship to study in Top Schools and courses like IIT, IIST,IISER etc Get the details here http://www.iisc.ernet.in/kvpy/). He stressed that there is a high need of students selecting research as a career. Pure science is also leading to great jobs with long lasting and healthy work environment than the get rich quick type jobs as in the IT field.

Dr. S.K. Satheesh of the Indian Institute of Science, Bangalore, who won the Bhatnagar Award for 2010, was felicitated at the meet.

 

The Genius Meet 2010 ended with felicitation of the top scoring students and the National Anthem

The eyes of the students were sparkling with inspiration and motivation while they came out of the meet.

Kinematics Numerical Problems

The velocity m, v m/s, of a particle is a straight line is given by
v = 6+pt+qt³
where t is the time in seconds after the particle passes through a fixed point O.
Given that t=2 s the distance of the particle from O is 16 m and its acceleration is 32m/s², calculate

a) the value of p and of q
b) the velocity of the particle at the instant when did acceleration is zero

Numerical Problems from Pressure, Density and Floatation

1. Ramesh buys 6 bottles of syrup each containing 1litre. Each empty bottle weighs 400g. The density of syrup is 1.2 g/cm3. What weight does Ramesh have to carry home?

2. The volume of 900g of a substance is 1000 cm3. Will the substance sink or float in water if the density of water is 1g/cm3. What will be the mass of water displaced by the substance?

Particle theory of light and refraction

According to particle theory of light if a light ray bends toward the normal while entering from medium 1 to medium 2 then how the velocity of light in medium 2 is greater than the velocity of light in medium 1 ?

Answer:

When a medium enters a denser medium from a rarer medium, it bends towards the normal. This is the observation we have in hand and this phenomenon is called refraction.

Sir Isaac Newton tried to explain the phenomenon of refraction using his particle theory. He said that the particles of the denser medium attracts the particles with stronger force towards it which makes it bend towards the normal.

If there is such a force of attraction, then the speed of light would increase inside a denser medium. When the velocity of light in different media was determined by Foucault and other scientists, it was found that the velocity of light in denser medium is less than that in a rarer medium. So, Newton’s explanation of refraction was proved wrong.

Power Factor

Divya asked:

“A COIL  HAS  A POWER  FACTOR OF 0.707 AT 60Hz, THEN ITS  POWER  FACTOR AT 180Hz WILL BE- ……….?

Ans:

(to be posted soon)

Nature of light, relativity and blackholes

Prasanna asked:

we know light has got dual nature. & blackholes has got enormous gravity from which even light cant escape. how can gravity can influence a mass less stream of particles like gravity?

Ans:

Do you know why solar eclipse is watched with great importance by the scientific community?

OK

Einstein’s theory of General Relativity was proved right(?) when bending of light by masses was observed in reality.
