Modern Physics Textbook

Modern Physics 5th Ed - this link provides the book.

The following is a summery-review of the book. Needs Editing.

A Review of Modern Physics (5th edition) by Tipler & Llewellyn.

As I have delved deep into this comprehensive book titled ‘Modern Physics’ by Paul A. Tipler & Ralph A. Llewellyn, I acknowledged how lucky I was to come to know many new and interesting topics in modern quantum physics, astrophysics and cosmology. In a broad sense, the book is divided into two parts. The First Part is titled Relativity & Quantum Mechanics: The Foundations of Modern Physics and the Second Part is titled "Applications of Quantum Mechanics and Relativity." The First Part mainly discusses the first half of the 20th century Physics. This include the proposition of quantum theory by Max Planck in 1900, which ushered in a new era of Physics, special & general theory of relativity, quantization of energy, various atomic models, quantum statistics, and wave-particle duality. 

The chapters of the 1st part are also arranged in close connection with that retrospect. The first 2 chapters concentrate on relativity and other related aspects such as Michelson-Morley experiment, Einstein's postulates, Lorentz transformation, superluminal speeds, relativistic energy, invariant mass, general relativity etc. The next, Chapter 3, deals with quantization of charge, light and energy, blackbody radiation, the photoelectric effect and the Compton effect. This chapter also includes an easily understood derivation of Compton effect. Chapter 4 & 5 discuss about further discoveries such as Rutherford model, Bohr model, de Broglie wavelength and the uncertainty principle. This area also includes the probabilistic interpretation of wave function and the limitations of the old quantum mechanics. Chapter 6 & 7 delve into an extensive discussion about the Schrodinger equation in 1, 2 & 3 dimension. It also reflect on wave function of hydrogen atom, electron spin, ground states of atoms, excited states and spectra of atoms etc. In chapter 8, we find deep analysis of the famous Bose-Einstein condensates, Bose-Einstein statistics, quantum statistics, and the properties of Fermion Gas. I think it is wise to mention that Dr. Bose, FRS was born in Bangladesh and worked in the University of Dhaka. In 1924, while working as a reader in DU, he wrote a paper deriving Planck’s quantum radiation law by using a novel way of counting states with identical particles. This paper was crucial in creating the field of quantum statistics.

The Second Part of the book is titled ‘Applications of Quantum Mechanics and Relativity.’ It includes chapters 9 through 13 of which Ch. 9 explores the molecular structure & spectra. This Ch. 9 also discusses Bonding mechanisms such as Ionic, covalent; lasers, masers, energy level of diatomic molecules and scattering, absorption or simulated emission are described in easily understandable terms. Chapter 10 deals with another fundamental part, the solid state physics. The structure of solids, classical and quantum theory of conduction, band theory of solids, semiconductors, junctions and devices and superconductivity is the primary focus of this chapter.

Chapter 11 deals with everything regarding Nuclear Physics. The composition and properties of nucleus, radioactivity, the nuclear force, nuclear reactions, fission & fusion etc. are mainly described here. In Ch. 12, the authors take us in the realm of particle physics. Topics such as fundamental force carriers and interactions, conservation laws & symmetries, and the standard model are discussed in such a way that anyone can understand these at ease. After that, the authors invite the reader to explore beyond the standard model and get acquainted with neutrino oscillations & mass, the proposition of a theory of everything etc. Chapter 13 starts with a grand tour of our known universe. The authors take us towards the sun, the stars & their evolution, the formation of galaxies & other superstructures, cosmology & gravitation, and the evolution & the future of our cosmos. In a nutshell, the whole experience with this book is really astounding. There is so much to know and learn from its wide range of topics. I will certainly recommend this book as a reference for Physics in the Intermediate or A level in our education curriculum. Apart from students and academicians, this book is a must read for enthusiast and ordinary people alike.

Sample Essay

Growing up in Bangladesh, I’ve always been of the notion that ‘research’ is only for the big scientists out there working for NASA. The fact that universities carry out research and are funded billions for it was not even in my realm of imagination. So, 18-year-old me was awestruck at the idea that I could write a research proposal myself. At the start, I actually had no idea where to begin. 

I’d recently been reading up on a lot of threads on Reddit relating to Artificial Intelligence as well as experiencing the wonders of AI firsthand through applications such as ‘Google Now’, ‘Cortana’, and ‘Google photos’ to name a few, my favorite being Google photos for its scarily accurate identification. I’d began by trying to collect enough material and research papers on the topics of Machine learning, Deep learning, Mathematics behind AI, along with the philosophical and cognitive aspects of AI. See, Artificial Intelligence is possibly the most open-ended topic out there right now, it is like a vast field ready for seeds to be sown and the benefits to be reaped eventually, some will come early on, some later. Eventually, I had to find someone more experienced than me to work with, bounce ideas off and maybe even help guide me in this vast open space, that’s where Tahsinur Rahman came in. I’d come across him in Nurture A.I.—Dhaka Chapter, a platform initiated to keep the AI community to stay updated with latest research, create and implement breakthroughs. 

Working with Tahsin, I’d begun development of my paper on “Machine Learning, Unsupervised Learning”. Beginning this process, I’d begun learning of how little I knew of the world of Artificial Intelligence. Even slightly scratching the surface, I’d learned how much more there is to Artificial Intelligence than just the Computer science side of it, than just the Mathematics of it. I was slowly coming into contact with the philosophical and cognitive aspects of AI, delving into books such as Gödel, Escher, Bach, Global Politics and Kant’s Critique of Pure Reason. Besides these, it was important to get to know more about what the leaders in the field of Artificial Intelligence were studying, and so came in the hundreds of research papers dealing with a range of things from the ethical issues of AI, the future of AI, Bayes’ Theorem, Boolean Algebra and even Ramanujan’s math, something critical to the future development of Machine Learning.

Rameesa’s revisit to Logophiles: After a semester at Lawrence University

First Report (Borno): She entered attired in a shimmery yellow-green salwar kameez; perhaps the same attire she wore in her university, adhered with an affection for the country she came from. Perchance the way she dressed personified her as a person – confident and adorable. She clearly loved being who she really was.
             She shared her part of the journey as she conversed. She is currently working on the Honey Bee Democracy, which is a mandatory text in freshman year irrespective of one’s major at Lawrence. The very day she stepped into the Logophiles class almost everyone she knew (except her mom) was against the notion that such tough route should have been taken. She emphasized the crucial importance of confidence in one’s self and not to stress out when working on any material. Such a strategy helped her to always pull ahead of letdowns. And – results never correspond with the fact that whether one will be accepted for admission or not – “Leave the results as it is, it’s not the end of the world if your grades are bad.” The one determinant that can make you stand distinguished is you “Research Papers”, she said. A technical research (can be more than one) paper will justify your devotion to science major, arts etc. and a General research paper will emphasize your linguistic ability. “Research paper is prime, it separates you from the others,” she confirmed.
            The vast reading materials the Logophiles students (Block 55/ August 2014, September 2014 and October 2015 reading materials) enabled the students to take strides through in a few months may sound excess but all of it yielded in usefulness to Ramisha. All the reading materials have always managed to leave a certain impact on her writing. It drastically increased her reading–speed and analyzing–skill, which are solely required to excel in finishing assignments in universities. She always had a constant communication with the ex-students of Logophiles, who helped her overcome certain fears to realize the bigger picture.
            “Sir, dance and music kore laabh kih?” was the first thing she said when sir stressed the importance of either an instrument or a type of cultural dance. “I do regret a lot not emphasizing more on music,” she said today. She is currently practicing music to take part in theatre at Lawrence. And the key is to NOT overwork, enjoying to work should be the only strategy.

Second Report (Siam): Ramisha Apu came for a visit from Lawrence University during her winter break and she brought along with her a book, The Pagoda Tree. Sir was absolutely delighted to see this book and let out a few joyful sighs. She spoke about things she had going on at Lawrence University. She had become an International Ambassador for Lawrence, planning extra-curricular cultural events involving dance and music and mentioned a book she had been working on – Honey Bee Democracy.

            Ramisha shared how the wide diverse discussions she had had in the Logophiles classes helped her in university as topics could be grasped more easily due to previous knowledge on them. She emphasized the critical importance of research papers, much more so than grades, as the research papers are what makes an application distinctive. The two different research papers highlights both the applicant’s linguistic and technical abilities. The importance of one’s own culture was discussed and how it allows one to stand from the monotonous crowds in university. As an example, she told us that a teacher she had never talked with before had wanted to speak with her. She stated that music plays an important role in Lawrence University and then sir went on to describe the flower that was in the video they had sent during the admissions and said he believes it had played an important role and must have had an impact on the admissions committee. Ramisha told us that being confident in yourself is important and said a very inspiring line – Even though I might fail, I will still do it.
            The conversation ended with the revelation that we had been a part of what is called a ‘forum theatre’: we constituted the audience, Ramisha Apu and sir as performers and the space as a stage.

Astronomy and Related Materials

I intend to link a few sites on Astronomy. For now, I am only putting up the link of

Bangladesh Astronomical Association

It is also to be noted that the Chief Executive Officer of the Association Mr. Mashur Ul Amin visited our class on last Thursday. We had a great many discussions which upon a few things that include - (1) the role of Classical Literature in improving our appreciation of Science; (2) the need for being dedicated once a student figures out her/his passion about a subject; (3) the importance of always getting into the company of like-minded people who shares a strong sense of intellectual inquiry. Mr. Mashur Ul Amin also mentioned how the reading of a few books have sealed his life-long passion for Astronomy. He particularly mentioned the following Books:

  1.  চাঁদের পাহাড় - বিভূতিভুষন বন্দ্যোপাধ্যায়
  2. সমুদ্রের স্বাদ - জ্যাক লন্ডন (কবীর চৌধুরী-র অনুবাদ)
  3. ওল্ড ম্যান এন্ড দ্যা ‍সি - আর্নেস্ট হেমিঙওয়ে (ফতেহ লোহানি-র অনুবাদ)

Day with Quantum Physics

Socialism in America

I intend to submit a couple of links related to socialism in America. For the first trial - I am adding the link to a Great and Wonderful book called Communism in America, which could serve as a companion volume to the Economic History of Soviet Union. I am adding the link to the the latter book as well.

The Roots of American Communism
The Rise and Fall of Soviet Economy
