IJR-1, Mathematics for All ... Syed Samsul Alam
January 31, 2015 [IISRR-International Journal of Research ] MATHEMATICS FOR ALL AND FOREVER Prof. Syed Samsul Alam Former Vice-Chancellor Alaih University, Kolkata, India; Former Professor & Head, Department of Mathematics, IIT Kharagpur; Ch. Md Koya chair Professor, Mahatma Gandhi University, Kottayam, Kerala , Dr. S. N. Alam Assistant Professor, Department of Metallurgical and Materials Engineering, National Institute of Technology Rourkela, Rourkela, India This article briefly summarizes the journey of mathematics. The subject is expanding at a fast rate Abstract and it sometimes makes it essential to look back into the history of this marvelous subject. The pillars of this subject and their contributions have been briefly studied here. Since early civilization, mathematics has helped mankind solve very complicated problems. Mathematics has been a common language which has united mankind. Mathematics has been the heart of our education system right from the school level. Creating interest in this subject and making it friendlier to students’ right from early ages is essential. Understanding the subject as well as its history are both equally important. This article briefly discusses the ancient, the medieval, and the present age of mathematics and some notable mathematicians who belonged to these periods. Mathematics is the abstract study of different areas that include, but not limited to, numbers, 1.Introduction quantity, space, structure, and change. In other words, it is the science of structure, order, and relation that has evolved from elemental practices of counting, measuring, and describing the shapes of objects. Mathematicians seek out patterns and formulate new conjectures. They resolve the truth or falsity of conjectures by mathematical proofs, which are arguments sufficient to convince other mathematicians of their validity. -

MIT Physics 8.251: String Theory 8.251: String Theory for Undergraduates
MIT Physics 8.251: String Theory 8.251: String Theory for Undergraduates Lecturer: Professor Hong Liu Notes by: Andrew Lin Spring 2021 Introduction It’s good for all of us to have our videos on, so that we can all recognize each other in person and so that the pace can be adjusted based on face feedback. In terms of logistics, we should be able to find three documents on Canvas (organization, course outline, and pset 1). Sam Alipour-fard will be our graduate TA, doing recitations and problem set grading. • There are no official recitations for this class, but Sam has offered to hold a weekly Friday 11am recitation. • Office hours are Thursday 5-6 (Professor Liu) and Friday 12-1 (Sam). If any of those times don’t work for us, we should email both of the course staff for a separate meeting time. Professor Zwiebach’s “A First Course in String Theory” is the main textbook for this course, which we’ll loosely follow (and have assigned readings and problems taken from). We won’t have any tests or exams for this class – grading is based on problem sets (75%) and a final project (25%) where we read Chapter 23 and do calculations and problems on our own. The idea is that we’ll learn some material on our own so that we can understand the material deeply! (Problem sets will be due at midnight on Fridays, with 50% credit for late submissions within 2 weeks.) Fact 1 The “outline” document gives us a roadmap of what we’ll be doing in this class. -
Photomath18.Pdf
Photomath18 1 - A DROPLET. The most outstanding mathematical aspect of this photo is that the circle on the leaf is extremely detailed which gives you the magnifying experience of this picture. You can see that the lines of the leaf are also very clear. The li nes are mathematically layed out because between the natural lines of a leaf there are all types of angles, big and small. The droplet which is the focus point of the picture, grasps everything together like a magnifying glass, which makes you think about the smaller picture in life as well as the big picture. The bright green color of the leaf also gives this image a fresh look and highlights the elegant lines which make you think about a roadmap. 2 - A PIECE OF HISTORY. Ever wondered where math came from? Well it’s been with us from the very beginning of the universe: from the spiraled Milky Way to the very plants on the earth. This photo is a fossil that represents the most know mathematical aspect of nature: The Golden spiral with the Fibonacci numbers. In geometry, a golden spiral is a logarithmic spiral whose growth factor is φ (phi), the golden ratio. A golden spiral gets wider (or further from its origin) by a factor of φ for every quarter turn it makes. The nature created this spiral to optimize the space but also to be efficient and she used it the most in the creation of plants. So, everywhere we look, we will see a little bit of math even if we don’t want to. -
Efficient Cubature Rules∗
Electronic Transactions on Numerical Analysis. Volume 51, pp. 219–239, 2019. ETNA Kent State University and Copyright c 2019, Kent State University. Johann Radon Institute (RICAM) ISSN 1068–9613. DOI: 10.1553/etna_vol51s219 EFFICIENT CUBATURE RULES∗ JAMES R. VAN ZANDTy Abstract. 67 new cubature rules are found for three standard multi-dimensional integrals with spherically symmetric regions and weight functions using direct search with a numerical zero-finder. 63 of the new rules have fewer integration points than known rules of the same degree, and 20 are within three points of Möller’s lower bound. Most have all positive coefficients, and most have some symmetry, including some supported by one or two concentric spheres. They include degree-7 formulas for the integration over the sphere and Gaussian-weighted integrals over the entire space, each in 6 and 7 dimensions, with 127 and 183 points, respectively. Key words. multiple integrals, Gaussian weight, cubature formula, integration rule, numerical integration, regular simplex AMS subject classifications. 65D30, 65D32, 41A55, 41A63 1. Introduction. We are concerned with estimating multi-dimensional integrals of the form Z (1.1) w(x)f(x) dx; Ω T where x = [x1 x2 ··· xn] , for the integration regions Ω and weighting functions w(x) given in Table 1.1. Applications of (1.1) include the evaluation of quantum-mechanical matrix elements with Gaussian wave functions in atomic physics [33], nuclear physics [18], and particle physics [19]. For applications in statistics, particularly Bayesian inference, see [11]. For applications in target tracking, see [2, 21]. We approximate these integrals using cubature formulas or integration rules of the form N X (1.2) Wif(xi); i=1 where the weights Wi and nodes or points xi are independent of the function f. -
2016 Annual Report
THE OREGON COMMUNITY FOUNDATION THE OREGON COMMUNITY FOUNDATION MESSAGE FROM THE BOARD 2 OCF 2016 IN REVIEW 4 OUR REGIONS 6 GRANTS AND SCHOLARSHIPS 34 OCF AND YOU 35 THE OCF FUNDS 37 INVESTMENT POLICY 54 FINANCIAL HIGHLIGHTS 55 OCF STAFF 56 Message From the Board Dear Friends of OCF, So much has happened at OCF in 2016. Where do we begin? With you — our many donors, volunteers and community partners. Without you, OCF couldn’t have achieved what we did in 2016. For starters, hundreds gathered at Crater Lake for the Britt Music & Arts Festival’s orchestral/ choral performance of “Natural History,” by composer Michael Gordon, thanks to a grant from our Creative Heights Initiative. At last year’s OCF Annual Luncheon, New York Times columnist and human rights leader Nicholas Kristof riveted the room talking about “opportunity inequity.” To create strategies to close that opportunity gap, more than 150 OCF volunteers attended the Statewide Leaders Gathering in September. For our board and staff, we held equity, diversity and inclusion sessions around the state. And our second annual “Women Give” event drew about 300 philanthropists and community leaders. Grantees met in their regions, aiming to improve children’s dental health, arts in the schools, and education for both students and parents. And we distributed pilot grants to support community water solutions in rural Oregon. We also published our 2016 Latinos in Oregon Report, relaying trends to guide changes in communities and personal lives. OCF’s Giving in Oregon and Volunteering in Oregon reports revealed good news: Oregonians, whatever their income, give at a higher rate than the national rate. -

What Are Mathematical Coincidences
What Are Mathematical Coincidences (and Why Does It Matter)? Downloaded from Marc Lange University of North Carolina at Chapel Hill [email protected] mind.oxfordjournals.org Although all mathematical truths are necessary, mathematicians take certain com- binations of mathematical truths to be ‘coincidental’, ‘accidental’, or ‘fortuitous’. The notion of a ‘mathematical coincidence’ has so far failed to receive sufficient attention from philosophers. I argue that a mathematical coincidence is not merely an unforeseen or surprising mathematical result, and that being a misleading com- bination of mathematical facts is neither necessary nor sufficient for qualifying as a mathematical coincidence. I argue that although the components of a mathematical coincidence may possess a common explainer, they have no common explanation; at University of North Carolina Chapel Hill on August 27, 2010 that two mathematical facts have a unified explanation makes their truth non-coincidental. I suggest that any motivation we may have for thinking that there are mathematical coincidences should also motivate us to think that there are mathematical explanations, since the notion of a mathematical coincidence can be understood only in terms of the notion of a mathematical explanation. I also argue that the notion of a mathematical coincidence plays an important role in scientific explanation. When two phenomenological laws of nature are similar, despite concerning physically distinct processes, it may be that any correct scientific explanation of their similarity proceeds by revealing their similarity to be no math- ematical coincidence. 1. The phenomenon to be saved All mathematical truths are necessary. Accordingly, there might seem 1 to be no place in mathematics for genuine coincidences. -
