“What are Significant Figures?”, “What are they used for?”, “What is their significance?” Students often ask these questions because why would you want to identify significant numbers, if you can do mathematical calculations without them, right? Where the idea of using significant figures might come off as unnecessary, it is a crucial concept that you need to learn if you want to improve the accuracy and

Are you looking for an algebra book that can carry you in your school or college life? If you are, you are at the right place. In this article I have listed the best algebra books for beginners as well as school and college students. These books are categorized in three sections: Beginners, High School and College Algebra Books. The purpose is to take you from

Math can be tricky at times. When you get stuck you reach out to your teachers, your classmates, and above all the Internet. There are some online math solvers and calculators that can help you out. While I have several online calculators myself, some are even better. There are over a dozen of online math solvers that can help you solving math problems either automatically or

I woke up today (29th June 2021) with a piece of news that the Riemann Hypothesis has been solved. But looks like that was all just a fuss. Indian newspapers, The Hindu, The Quint, Hindustan Times, etc., everyone reported that a Hyderabad-based mathematician has succeeded in solving this $1 million question. Riemann Hypothesis is one of the unsolved problems in mathematics and it has a bounty

Looking for the best Real Analysis books? If yes, then you are at the right place. In this article, I have listed and reviewed the top 10 real analysis books sorted by their popularity and content quality. These books are not just the best real analysis books but these also create a solid foundation for you going ahead. What makes me eligible to say which book

This is in continuation of my article on getting started with measure theory. As a measure theory student, you may have gone through the trouble of selecting the best books on measure theory. I had the same troubles once. That’s why I have collected the 15 best measure theory books for graduate students. Here is the list: Photo Title Buy Measure Theory and Fine Properties of

Cryptography or Cryptology is an interesting topic in mathematics and related sciences. It is a branch in math that mostly relies on the practical application of the subject. In 2011, I came to know about this while reading the Elementary Number Theory by David M. Burton. It has a little chapter on Cryptography focused primarily for number theory students. But this whole idea of cryptography opened

Are you interested in maximizing profits and minimizing risks while betting on sports? Well, who isn’t? If you want to know whether a wager is worth the pursuit or not, you should be well versed with the mathematics of betting odds. Basically, there are three types of odds involved in this process: American (Moneyline) Decimal Fractional These three types of odds are essentially representatives of different

Abel prize is one of the most prestigious awards given for outstanding contribution in mathematics, often considered as the Nobel Prize of Mathematics. Niels Henrik Abel Memorial fund, established on 1 January 2002, awards the Abel Prize for outstanding scientific work in the field of mathematics. The prize amount is 6 million NOK (about 1010000 USD) and was awarded for the first time on 3 June 2003. Following

Formulas are the most important part of mathematics and as we all know one is the backbone of the latter. Considering there are thousands of mathematical formulas to help people develop analytical approach and solve problems easily — there are some that go beyond. Some formulas aren’t just timesaving but those also do wonders. In this article I have collected some of the finest time-saving formulas

Any integer greater than 1 is called a prime number if and only if its positive factors are 1 and the number p itself. The basic ideology involved in this post is flawed and the post has now been moved to Archives. Prime Generating Formulas We all know how hard it is to predict a formula for prime numbers! They have extremely uncertain patterns at various number ranges. Some prime

Our reader Eswar Chellappa has sent his work on the solution of ‘3X+1’ problem, also called Collatz Conjecture. He had been working on the proof of Collatz Conjecture off and on for almost ten years. The Collatz Conjecture can be quoted as follow: Let $\phi : \mathbb{N} \to \mathbb{N}^+$ be a function defined  such that: $$\phi(x):= \begin{cases} \frac{x}{2}, & \text{if } x \text{ is even } \\

Online communities are groups of web savvy individuals who share communal interests. A community can be developed with just a single topic or by a bunch of philosophies. A better community binds its members through substantial debates. Mathematics is a very popular communal interest and there are hundreds of online communities formed in both Q&A and debate styles. Some mathematical communities are so immense that they

Linear Space or Vector Space over a field K Definition: The linear space over a field K is a non-empty set along with a function $+ : X \times X \to X$ called linear/vector addition  (or just, ‘addition‘) and another function $ \cdot : K \times X \to X$ called scalar multiplication, such that for all elements $x, y, z, \ldots$ in $X$ and $1, k,

It was mid 2012, the first time I installed TeXstudio version 2.3, on my PC. ‘Peaceful‘ was the word I used to describe it then after. TeXstudio has now gradually inched to version 2.12.22 and by time being even more peaceful and wonderful. Wonder why did I call it ‘peaceful’? Writing LaTeX is a real pain, when you are willing to write a long document or article, which in my case are

Infinitely many answers questions are possible to the answer, “No”. So, our real task should be to find one of THOSE many, which seems to be a perfect one. A simple and the first ever logical approach of giving answers to a question is to derive answers from the question, that is, replace some words of the question with reasonable ones and make a statement. (Conversely but )

Square Integrable function or quadratically integrable function $\mathfrak{L}_2$ function A function $y(x)$ is said to be square integrable or $\mathfrak{L}_2$ function on the interval $(a,b)$ if $$\displaystyle {\int_a^b} {|y(x)|}^2 dx <\infty$$ or $$\displaystyle {\int_a^b} y(x) \bar{y}(x) dx <\infty$$. For further reading, I suggest this Wikipedia page. $y(x)$ is then also called ‘regular function’. The kernel $K(x,t)$ , a function of two variables is an $\mathfrak{L_2}$ – function if atleast one
