If you know anything about physics, then you’ll know that it’s important. Simply put, the study of physics is the study of matter, energy, and the interaction between them. However, this is putting it very simply, one only needs to look back in time to see where we’d be without this study. Scientists have been discredited, exiled and even killed, for the simple fact that the world was not moving as fast as they were, intellectually speaking. We know a whole lot better now, but there is still a world of theorems and laws to be discovered. Physics affects absolutely everything, from an apple falling off of a tree to you kicking a ball, to the great celestial movements that greatly change the universe we live in.
Physics is the source of success, opposed to failure, in the face of our own proper understanding of the whole Universe, which includes Earth and the science within, obviously. It can often determine the difference/s, between the physically possible, probable and impossible, in science and in turn in everything else there physically is. Physics is the key to success in mankind’s developments, again as opposed to our failure, a threat to life, or death itself.
Physics is there to locate our boundaries within science and in turn our existence and those of the future, it is definitely a matter of the people alive today, trying to provide every possible measure available to ensure the safety of those who inherit the Earth, but unfortunately as we have witnessed in the past, this method has previously witnessed us not completely ensuring the safety, of those alive today. Physics is part of how we research and study the facts, of how we stop the potential hazards of our discovery, from interfering with our progress and to stop potential dangers from happening. Science is the most potentially dangerous thing in the Universe, physics is the measurement that guides us to safety.
But how easy is it to learn physics? The great thinkers of old would spend years and years trialling and testing theories and laws, just to know simple things that we know today. Having said that, learning the intricacies of fundamental laws of physics like motion and momentum are not a walk in the park, they take a lot of time and focus in order to understand fully. But, thanks to modern technology and a whole load of helpful Universities and Institutions hard work, you can learn a lot about physics without ever leaving your home! I speak, of course, of online physics courses!

One Hundred Years of Gravitational Waves
Via Massachusetts Institute of Technology
Last year the world celebrated the centennial of Einstein’s formulation of General Relativity. It was a bold new concept of gravitation which replaced Newton’s gravitation by a geometric theory in which matter distorts the geometry of space-time and the geometry tells matter how to move. Renowned physicist Rai Weiss is best known as one of the original creators of the Laser Interferometer Gravitational-Wave Observatory (LIGO). Join him as he explores the history of this amazing project and the technology that made it a reality.

In this Master Class, Linde discusses the evolution of these ideas over the past decades and what the future of cosmology holds.
The Early Universe
Via Massachusetts Institute of Technology (Flexible duration)
Scientists know now that the Universe has been around for quite some time. Though the first million years can be quite patchy in terms of proven events, scientists are still fascinated by what happened in those early days. The Early Universe provides an introduction to modern cosmology. The first part of the course deals with the classical cosmology, and later part with modern particle physics and its recent impact on cosmology.

Physics is considered as one of the most difficult subjects in science. Often, physics lectures are flooded with heavy formulae, including calculus. In this course, efforts have been made to help students feel physics in addition to learning. Using minimal algebra without calculus, most of the key concepts in classical mechanics have been explained. Various real physics demonstrations also help students to grasp physics from everyday experience.
Mechanics: Motion, Forces, Energy and Gravity, from Particles to Planets
Via New South Wales University (8 weeks long)
Most of the phenomena in the world around you are, at the fundamental level, based on physics, and much of physics is based on mechanics. Mechanics begins by quantifying motion, and then explaining it in terms of forces, energy and momentum. This allows us to analyse the operation of many familiar phenomena around us, but also the mechanics of planets, stars and galaxies.
How Things Work: An Introduction to Physics

From rotational and translational motion, to inertia, to gravity. After this you’ll be completely ready to take on more advanced theories and laws.
Exploring Quantum Physics
Via University of Maryland (3-4 weeks long)
Quantum physics is the foundation for much of modern technology, provides the framework for understanding light and matter from the subatomic to macroscopic domains, and makes possible the most precise measurements ever made. More than just a theory, it offers a way of looking at the world that grows richer with experience and practice. Our course will provide some of that practice and teach you “tricks of the trade” (not found in textbooks) that will enable you to solve quantum-mechanical problems yourself and understand the subject at a deeper level.
From The Big Bang to Dark Energy
Via The University of Tokyo (4 weeks long)
We have learned a lot recently about how the Universe evolved in 13.7 billion years since the Big Bang. More than 80% of matter in the Universe is mysterious Dark Matter, which made stars and galaxies to form. The newly discovered Higgs-boson became frozen into the Universe a trillionth of a second after the Big Bang and brought order to the Universe. Yet we still do not know how ordinary matter (atoms) survived against total annihilation by Anti-Matter. The expansion of the Universe started acceleration about 7 billion years ago and the Universe is being ripped apart. The culprit is Dark Energy, a mysterious energy multiplying in vacuum. I will present evidence behind these startling discoveries and discuss what we may learn in the near future.
Dark Matter in Galaxies: The Last Mystery
Via Iversity (3 months long)
