Math and Logic

Mathematics is an invention or discovery ? Bill Thurston, a famous topologist from Berkeley , said that a mathematician is one who helps in the human understanding of mathematics, he endorsing the view that mathematics is divine and that it resides entirely in the human mind. All the same, we know that mathematicians conceived of black holes long before physicists actually found them, even when certain important problems in mathematics – and, more importantly, their solutions – belonging to the so-called low-dimensional topology were motivated by certain considerations arising in theoretical physics! This dual nature of mathematics combining in itself elements of art and science is singularly unique to the practice of mathematics .....

My School Visit

Last week , i got chance to visit few primary schools. Teachers need considerable time for training, support to help them to rethink their teaching practice, their discipline, their students' need and capacities to impart with real-world approach.Teachers said that several factors inhibited them from teaching included time for planning; students’ reading abilities; time for professional development, mid day meal plan and lot of other government works..

Math Education

We often treat student 's learning problems lightly as if they did not matter. We also know that not all student do not attack mathematics or any other subject with the same energy and enthusiasm. Pupils should not only be exposed to the structure of mathematics but also the historical and cultural aspects.Some knowledge of ethno-mathematics such as stories and games should be introduced whenever... it is necessary to make the lesson more interesting. Some pupils are interested in theoretical mathematics whereas others, probably the majority, are motivated by a historical approach. Still others are excited by the relationships between mathematics and art, mathematics and music or mathematics and language.Moreover, application of mathematics interests many pupils. We have heard much about mathematics anxiety, described as reluctance and fear to engage in mathematics- related activities. Individuals who exhibit such anxiety do not enjoy doing mathematics, especially in public.Most individuals with mathematics anxiety are beyond school level. We hear them proclaiming, for example, "I was very good in mathematics when I was in standard 8th. However, things have changed now .They find themselves learning certain mathematical ideas they are not ready because they fail to see their immediate application.As a result, some pupils and students begin to dislike mathematics and stop doing mathematics. Success in any subject in class depends on hard work, teachers' ability to deliver lessons and good grooming of the parents.

Indian agriculture..Present perspective

The purchasing power of the rural population throwing enormous demand for goods and services and boosting the national economy tremendously.But Darling's statement (1925), that "the Indian peasant is born in debt, lives in debt and beque...aths debt," still remains true for the great majority of working households in the countryside. Rural households need credit for a variety of reasons. They need it to meet short-term requirements for working capital and for long-term investment in agriculture and other income-bearing activities. Agricultural and non-agricultural activity in rural areas are typically seasonal, and households need credit to smooth out seasonal fluctuations in earnings and expenditure.That is the reason of quitting agriculture among young genration though is observed around the country.Agriculture, with its large dependent population in villages has to thrive and flourish, in order to secure rural prosperity by enhance in productivity,Strengthening forward and backward linkages ,Encouraging emergence of a market mechanism ,watershed development.

Why we need Prime Numbers...

Prime numbers have intrigued curious thinkers for centuries. On one hand, prime numbers seem to be randomly distributed among the natural numbers with no other law than that of chance. But on the other hand, the global distribution of prime...s reveals a remarkably smooth regularity. This combination of randomness and regularity has motivated researchers to search for patterns in the distribution of primes that may eventually shed light on their ultimate nature.it is not a matter of whether we need prime numbers or not. Since they exist, what are we going to do with them - if anything?Why do we need mountains? Since they exist why not climb them? But perhaps the best reason to study primes is that they are simultaneously elementary and mysterious. It's remarkable just how little we know about these numbers after pondering them for millennia. For many mathematicians, that alone is sufficient motivation.There are thousands of pattern in prime,..one of them whom i like is..The prime number 73,939,133 has a very strange property. If you keep removing a digit from the right hand end of the number, each of the remaining numbers is also prime. It's the largest number known with this property.
Take a look: 73,939,133 and 73,939,13 and 73,939,1 and 73,939 and 7,393 and 739 and 73 and 7 are all prime number....See More

Attention deficit in kids

A study says Attention Deficit Hyperactivity Disorder among children is increasing .Symptoms of ADHD include restless feeling, often fidgeting with hands or feet, running, climbing, or leaving a seat, blurting out answers before hearing the whole question, and having difficulty waiting in line .ADHD can cause significant interference in a child's academics and interpersonal relations.A of factors that may contribute to ADHD including genetics, diet and social and physical environments.The survey was conducted in Delhi-NCR, Mumbai, Ahmedabad, Kolkata, Bangalore, Chennai, Hyderabad, Chandigarh, Jaipur and Lucknow. It covered around 1,000 school teachers, who said that they have 1-3 children who are diagnosed with ADHD in every single class.

Mathematics Teaching

For the countless kids who sit through math class and wonder about the usefulness of algebra, geometry or calculus.Historically most "appealing" jobs haven't required mathematics ; rather, at most, only an ability to use calculators (old) and computers, internet (new). As a result, most kids see math as a giant bag of forgettable information used only to challenge them academically.In the wake of the Japanese earthquake or with all the recent flooding in parts of Canada, having effective evacuation plans are prepared by modelling..mathematical modelling is nothing new. The ancient Egyptians used geometry to model the world as they knew it and to predict when the Nile River would flood. At the height of the H1N1, or swine flu, outbreak in 2009, researchers from Toronto's St. Michael's Hospital used air traffic pattern data to accurately predict how the virus would spread around the world.it's important that the mathematics community showcase the role we are playing and use this to excite kids and the public on the power of mathematics.

Olympiad Programmes For Remote Regions

With nearly zero student representation in the international Olympiads from regions like Jammu and Kashmir, Himachal Pradesh, Uttaranchal and the north-East states, the Homi Bhabha Centre for Science Education (HBCSE) has decided to start exposure-cum-training camps for schools and colleges from these areas.HBCSE is the country’s nodal centre for Olympiad programmes in Mathematics, the Sciences and Astronomy. The programmes aim at promoting excellence in Science and Mathematics among pre-university students. HBCSE have decided to start a large number of exposure camps for school and college teachers of regions which are rarely represented in these competitions. HBCSE want students to consider a career in Science. Another objective is to drive up the higher secondary science education in our country by training science teachers.Teachers from schools and colleges in these areas lack in expertise and training required to handle tough competitions like the Olympiads. Some may not be even aware of this event. Another reason could be insurgency and violence in places like Jammu and Kashmir and some pockets of Assam.Another focus area will be interior regions in states like Bihar and Chhattisgarh. The camps will start by the end of November. Teachers will be exposed to the experimental programmes at HBCSE; training will be conducted and some of the experimental kits will be given to the teachers.The Olympiads have a rigorous, three-tier selection process, which includes a nationwide examination. Around 35 students are selected to participate in an intensive “orientation-cum-selection camp” at HBCSE, after which the final team is shortlisted.The HBCSE has written to the respective state education departments, Kendriya Vidyalayas, Indo-Tibetan schools and Sainik schools, asking them to help identify teachers to attend the camp.

Regional Mathematical Olympiad

The Regional Mathematical Olympiad , sponsored by the National Board for Higher Mathematics and coordinated by the Department of Mathematics, Cochin University of Science and Technology, will be held on December 5 at several centres in Kerala.The olympiad is meant for talented students from Class X to XII and is the first stage for selecting an Indian team for the International Mathematical Olympiad to be held in the Netherlands in July in 2011. The first five rank holders will get cash awards sponsored by KSCSTE and prizes from Prof C S Venkataraman Memorial. Applications with details such as name, class, address and email should be forwarded by principals of recognised schools, along with DD for `30 each entry in favour of Regional Coordinator, INMO, payable at any bank in Kochi, should reach P M Mathew, Department of Mathematics, St Joseph's College, Devagiri, Kozhikode 673008, before October 25. For an information brochure and old question papers, send a selfaddressed, `25stamped envelope of size 10 x 8 to A Vijayakumar, Regional Coordinator INMO, Department of Mathematics, Cusat, Kochi 22 or call 09447608851, or mail to vambat@gmail.com.

Autonomy for IIT, IIM

The finance ministry has rejected a long-standing demand of the IITs and the IIMs seeking freedom from government interference in creating faculty posts. HRD ministry had proposed the IITs, IIMs and other top technical education institutions be allowed to create teaching posts on their own, while keeping the ratio of teaching to non-teaching posts intact.The HRD minister has on occasions over the past year said he wants to increasingly grant autonomy to the IITs and the IIMs.This proposal was aimed at freeing up some of the country’s best higher educational institutions to create faculty jobs based on their needs at a time rather than on bureaucratic norms.The proposal was seen as critical because of the Foreign Education Providers Bill, that will allow foreign varsities to enter India.Freeing up creation of faculty jobs at the IITs and IIMs would have helped them compete better with foreign universities that enjoy this freedom.The IITs and the IIMs have on occasions lost out on hiring renowned experts in a department because of no vacancies at the appropriate post.The percentage of vacancies in teaching posts varies from 15 per cent to 40 per cent across the IITs and the IIMs.The National Institutes of Technology (NITs), which were to be also covered under the HRD ministry proposal, also face a huge faculty shortage.

Proficiency Test System (PTS)

The CBSE has decided to introduce an optional “proficiency test” in June 2011 for those students who will clear Class X in March 2011 on the new pattern of continuous and comprehensive evaluation (CCE) rather than traditional board examination.Proficiency Test System (PTS) and would be available for the class X students who opted for continuous and comprehensive evaluation last year. PTS would not be a compulsion. Only interested students would opt for the same and take the test accordingly in June. PTS would be available in all subjects namely, English, Maths, Science, Social Studies and Hindi. The test would contain multiple-choice questions. However, the number of questions and the duration of the paper are yet to be finalised. The board is also trying to figure out whether the candidate could take the test online or not. The question papers would be set by institutions of repute. While Central Institute for English and Foreign Languages would prepare the questionnaire for English, Bhabha Atomic Research Centre, Mumbai, be responsible for Science and Maths question papers. The board has also contacted Indian Council For Social Science Research and Central Hindi Institute for social studies and Hindi respectively.

IIT-JEE REFORM

Rajiv Kumar, professor of computer science at IIT Kharagpur, has submitted proposal for IIT-JEE reform.Kumar has not suggested 70% marks in class XII as the eligibility condition to appear for IIT-JEE.Kumar has suggested a single examination -- replacing IIT-JEE, AIEEE and all other states' JEEs -- by which a student, after securing a UID card, can have both all-India as well as state rank. A single (all-India level and state level each) merit list should be prepared by which one can seek admission in one of the engineering colleges, including IITs, IISERs, NITs, IIITs, states and others.there should be three sittings of the same examination conducted thrice over a fortnight or a month. An aggregated score over three sittings of the examination should be considered for the final ranking. The single test, Kumar has proposed, should be conducted with four subjects of PCMA (physics, chemistry, mathematics and aptitude) with equal weightage for all the four. There should not be any additional test to test PCMA/PCMB, which is already tested by the single test. The new proposal also says that the curriculum for entrance test should have more stress on the Plus 2 syllabus. He has argued that the skewed marks distribution in IITs is due to the fact that questions are unnecessarily complex; questions do not test much of analytical or conceptual knowledge; questions do not have proper coverage. Therefore, his proposal says, care should be taken on setting correct, unambiguous and within the syllabi Multiple Choice Questions (MCQs). It says proper and balanced questions of Plus Two standard should be set. This will reduce dependence on coaching and students will concentrate on the school level examination.

common entrance examination

Union human resources development ministry has finalised a proposal for single entrance exam for all engineering institutes like IITs, NITs and engineering colleges across the country. The proposal is likely to be put before the HRD council.HRD ministry is expected to push for a common entrance examination test for all engineering institutes in the country, effectively doing away with the IIT-JEE. HRD council is the highest decision making body of the premiere institution. The step of the HRD ministry assumes significance as an IIT directors’ committee had recommended a two-tier entrance exam structure for the prestigious institutes.

Sahal Kaush

Delhi boy Sahal Kaush has cracked the IIT-JEE exam at the age of 14 this year. He has taken admission in an undergraduate course at the IIT institute in Kanpur. Kaushik, who had secured the 33rd rank at all-India level in the IIT-JEE exam this year, has opted for the five-year integrated MSc (Physics) course.There is no age limit for admission into undergraduate courses. A student has to be intermediate pass only. Sahal is the youngest student to take admission in the IIT this year. He completed his class 12 from Vandana International School in Dwarka, Delhi, securing 78 per cent marks.

AIEEE CCB

According to the new system outlined by the Central Counselling Board (CCB) of AIEEE, students allotted a seat in any round till the first three rounds of counselling will have to take provisional admission. This change practically extinguishes the option that the students so far had, that of moving to a better institute and a branch of their choice even after reporting for admission. Under the new rules, there is room only for 'internal sliding' (movement of position within the institute) that can be availed of, with the option of movement across NITs over. In short, it will leave students trapped in NITs not necessarily of their choice: an irony in an age where there is so much of premium on choice. With results of third round of counselling to come on Sunday, students from all over the country have launched online protests (protestagainstccb.webs.com and entrancecorner.com) demanding a change in the rules so that deserving students get NITs of their choice. Students have even found a major inconsistency in CCB's argument that "sliding" will be possible within the institution. "If a student cannot change his institution how will a seat be vacated to upgrade any other student's branch," asks one student. The third flaw being pointed out is that after the fourth round of counselling, not so popular branches in top NITs will still be vacant and these will go to low-ranked students. Upgradation in the same NIT, students say, can also create a situation of a low-ranker getting a better branch. How? Students explain it through an illustration. Suppose a student with an AIR of 6,500 gets computer engineering in NIT Durgapur and another student with AIR 6,000 gets computer engineering in NIT Allahabad. In case the second student chooses to join any other engineering college like IIT, BITS and others, the vacancy in Allahabad will go to a student within the institute, whatever be his rank, and not to someone with a better rank. Students feel the flaw can still be rectified. They say there will be a large number of dropout seats after the fourth round of counselling since many students who have got through to other engineering colleges will wait till that round. But the vacancies thus created will not help students who have already taken admission in NITs after the third or fourth round. Therefore, students have demanded open upgradation — from one institute to another. They also want CCB to allow one round of counselling after refunds have been made to those who did not take admission.
