Object Oriented programming Concepts in C++ C++ and Object Oriented Programming Object Oriented programming is a programming style that is associated with the concept of OBJECTS, having datafields and related member functions. Objects are instances of classes and are used to interact amongst each other to create applications. C++ can be said to be as C language with classes. For Example : We consider human body as a class, we do have multiple objects of this class, with variable as color, hair etc. and methods as walking, speaking etc. Now, let us discuss some of the main features of object oriented programming which you will be using in C++. ObjectsClassesAbstractionEncapsulationInheritanceOverloadingException Handling Objects Objects are the basic unit of OOP. Class It is similar to structures in C language. Abstraction Abstraction refers to showing only the essential features of the application and hiding the details. Encapsulation It can also be said data binding. Inheritance Polymorphism Polymorphion makes the code more readable.
How To Lucid Dream Tonight How To Lucid Dream Lucid Dreaming is the ability to be aware of your dreams, and control them. I know, I know: You want to know how to lucid dream right now, easily, don’t you? Lots of people do. You’re not alone! Before we go any further, this is going to be a fairly long post, so feel free to bookmark it if you want to come back to it later. So assuming you’re a beginner and don’t know much about the subject, Lucid Dreaming is basically the ability to ‘wake up’ in your mind and control your dream. To get more of a background on it, read our introduction. Now that that’s out of the way, we can start talking about the easy way to lucid dream tonight. So it’s about having one tonight, with as little practice as possible, for the people who want results fast. Will this be your first Lucid Dream? Something to consider before we dive in is whether this is your first lucid dream or not. If you’re looking for a way to lucid dream tonight and it’s your very first one, (how exciting!) *Almost. – Enjoy it!
Why You Should Learn To Code (And How To Actually Do It) In the Lost Interview with Steve Jobs, Apple’s co-founder said, “I think everybody in this country should learn how to program a computer because it teaches you how to think.” I like to think of coding as applied math and sciences because it teaches us an iterative approach to solving problems and testing out our ideas. While I don’t consider myself a coder, apart from HMTL/CSS I don’t code in my daily work, I did find that learning the basics of how to code on CodeAcademy has done wonders for improving my problem solving skills. Now that software is eating the world by automating all kinds of routine jobs, the basic knowledge of how lines of code create the digital worlds we explore every day is becoming a fundamental digital literacy. Watch the video below to discover why coding is the new “superpower” that isn’t being taught in in 90% of schools. Fortunately, it has never been easier to learn how to code. There many different options to learn to code online for free. 1. 2. 3. 4. 5. 6.

CS50x: Introduction to Computer Science CS50x is Harvard College's introduction to the intellectual enterprises of computer science and the art of programming for majors and non-majors alike, with or without prior programming experience. An entry-level course taught by David J. Malan, CS50x teaches students how to think algorithmically and solve problems efficiently. Topics include abstraction, algorithms, data structures, encapsulation, resource management, security, software engineering, and web development. Languages include C, PHP, and JavaScript plus SQL, CSS, and HTML. Problem sets inspired by real-world domains of biology, cryptography, finance, forensics, and gaming. Students who earn a satisfactory score on 9 problem sets (i.e., programming assignments) and a final project will receive a certificate from HarvardX.

A Mathematical Proof That The Universe Could Have Formed Spontaneously From Nothing — The Physics arXiv Blog One of the great theories of modern cosmology is that the universe began in a Big Bang. This is not just an idea but a scientific theory backed up by numerous lines of evidence. For a start, there is the cosmic microwave background, which is a kind of echo of the big bang; then there is the ongoing expansion of the cosmos, which when imagined backwards, hints at a Big Bang-type origin; and the abundance of the primordial elements, such as helium-4, helium-3, deuterium and so on, can all be calculated using the theory. But that still leaves a huge puzzle. What caused the Big Bang itself? For many years, cosmologists have relied on the idea that the universe formed spontaneously, that the Big Bang was the result of quantum fluctuations in which the Universe came into existence from nothing. That’s plausible, given what we know about quantum mechanics. Today they get their wish thanks to the work of Dongshan He and buddies at the Wuhan Institute of Physics and Mathematics in China.
Model Thinking This course will consist of twenty sections. As the course proceeds, I will fill in the descriptions of the topics and put in readings. Section 1: Introduction: Why Model? In these lectures, I describe some of the reasons why a person would want to take a modeling course. To be an intelligent citizen of the worldTo be a clearer thinkerTo understand and use dataTo better decide, strategize, and design There are two readings for this section. The Model Thinker: Prologue, Introduction and Chapter 1 Why Model? Section 2: Sorting and Peer Effects We now jump directly into some models. In this second section, I show a computational version of Schelling's Segregation Model using NetLogo. NetLogo The Schelling Model that I use can be found by clicking on the "File" tab, then going to "Models Library". The readings for this section include some brief notes on Schelling's model and then the academic papers of Granovetter and Miller and Page. Notes on Schelling Granovetter Model Miller and Page Model
