Physics (from Ancient Greek: φυσική (ἐπιστήμη) phusikḗ (epistḗmē) “knowledge of nature”, from φύσις phúsis "nature") is the natural science that involves the study of matter and its motion through space and time, along with related concepts such as energy and force.

More broadly, it is the general analysis of nature, conducted in order to understand how the universe behaves.

Physics is one of the oldest academic disciplines, perhaps the oldest through its inclusion of astronomy. Over the last two millennia, physics was a part of natural philosophy along with chemistry, certain branches of mathematics, and biology, but during the Scientific Revolution in the 17th century, the natural sciences emerged as unique research programs in their own right. Physics intersects with many interdisciplinary areas of research, such as biophysics and quantum chemistry, and the boundaries of physics are not rigidly defined. New ideas in physics often explain the fundamental mechanisms of other sciences while opening new avenues of research in areas such as mathematics and philosophy.



Physics also makes significant contributions through advances in new technologies that arise from theoretical breakthroughs. For example, advances in the understanding of electromagnetism or nuclear physics led directly to the development of new products that have dramatically transformed modern-day society, such as television, computers, domestic appliances, and nuclear weapons; advances in thermodynamics led to the development of industrialization, and advances in mechanics inspired the development of calculus.

Let There Be Light It’s easy to take light for granted and assume that we know everything there is to know about it—after all, it’s everywhere.

Physicists Just Discovered a New Form of Light

But as it turns out, we might have only scratched the surface. Today, physicists announced that they have discovered a new form of light. It’s completely different from our existing rules regarding light and angular momentum, showing that light can take on new and unexpected forms, and these could fundamentally change our current understanding of electromagnetic radiation. The TCD press release explains how angular momentum operated in relation to light: “A beam of light is characterised by its colour or wavelength and a less familiar quantity known as angular momentum.

Gravity isn't a Force, So How Does it Move Objects?

You may have heard that gravity isn’t a force. This is true. Gravity is not a force; however, this truth leaves us with a number of questions. For example, we’re commonly told that gravity “pulls” things towards massive objects. I know that, when teaching introductory physics (especially in elementary classes), some teachers and textbooks say things like, “Earth’s gravity pulls objects towards the center of the planet.” But how can this be? To begin answering these questions, you first need to understand that “accelerate” is the proper term, not “pull.” Meet the Rubber Sheet To delve into this a bit more, thanks to Albert Einstein’s Theories of Relativity, we know that energy tells spacetime how to bend.

Imagine an archipelago where each island hosts a single tortoise species and all the islands are connected — say by rafts of flotsam.

Beyond the Bell Curve, a New Universal Law

As the tortoises interact by dipping into one another’s food supplies, their populations fluctuate. In 1972, the biologist Robert May devised a simple mathematical model that worked much like the archipelago. He wanted to figure out whether a complex ecosystem can ever be stable or whether interactions between species inevitably lead some to wipe out others. By indexing chance interactions between species as random numbers in a matrix, he calculated the critical “interaction strength” — a measure of the number of flotsam rafts, for example — needed to destabilize the ecosystem. Below this critical point, all species maintained steady populations. Little did May know, the tipping point he discovered was one of the first glimpses of a curiously pervasive statistical law.
