cool physics concepts

If you're looking for cool stuff to buy, this wireless robot needs a home. Let's refresh our fundamental math concepts that will be used often in our physics course. These questions make use of concepts taught at the high school and college level (mostly first year). Things do get pretty hairy when you need a description that's both quantum and relativistic, which is the regime of high-energy physics. Somehow these add up to give them certain traits of solids, too. Before it was a TV show, the Big Bang Theory was an important explanation for the origin of our universe. What it means is that, even though light doesn’t have any mass, its path is affected by things that do—such as the sun. Understanding the Heisenberg Uncertainty Principle. This probability is fundamental to the system, not merely a result of ignorance. Guides and question banks covering Atomic structure, Electromagnetic waves, Kinetic Theory and many more Physics a-level topics. Here are some real life examples that can explain the laws in a better way. That’s okay—classical physics proved some pretty cool concepts too. Physics … "Surely You're Joking, Mr. The Martian This film, based on the debut novel by Andy Weir, is a cross of Apollo 13 (also on this list) and Robinson Crusoe (or Castaway, another Tom Hanks film), tells the story of an astronaut injured and accidentally stranded alone on the planet Mars.In order to survive long enough to be rescued, he must leverage every resource with scientific precision. 2. Still, the Anthropic Principle poses an intriguing intellectual puzzle. It doesn’t. See more ideas about Physics, Quantum physics, Astrophysics. For example, there are a bunch of variations of the double slit experiment that are even more insane than the one I talked about here. The implications of this process are huge—it means that information (in this case, the direction of spin) can essentially be teleported anywhere in the universe. Sometimes, students may be required to write a physics essay on physics science topics or topics related to physics. Of course, time can only slow down so much, and the formula works out so that if you’re moving at the speed of light, time isn’t moving at all. What it says: Newton’s universal law of gravitation states that … But that’s not how particles would react to a double slit—they would just go straight through to create two lines on the wall that match up with the slits. They also have some pretty accurate ways of measuring the total mass we can observe, and here’s the twist—the two numbers don’t match up. The relationship between Geography and Physics. One is a solid chunk of matter, and the other is a radiating beam of energy, kind of. The Roles physics plays in the health care industry. Whether you are exploring laws of motion, sound waves, or light, physics is everywhere! Attempts to solve the problem have led to some intriguing theories. Some are full-blown theories, such as relativity, but others are principles (assumptions upon which theories are built) and some are conclusions made by existing theoretical frameworks.All, however, are really weird. Our mission is to provide a free, world-class education to anyone, anywhere. Sphero is a new, smart robot that you can program and control right from your phone. Matter and light have properties of both waves and particles simultaneously. It’s true—matter and energy are just two sides of the same coin. I know that sounds ridiculous (and it’ll sound even crazier when we get to Number 1), but there’s concrete evidence that proves light is a wave, and other concrete evidence that proves light is a particle (ditto for electrons). Mechanics is the oldest branch of physics. Newton’s Laws. For more details, see our Privacy Policy. : Adventures of a Curious Character (Paperback) by Richard P. … From the foundation basics to more abstract ideas, these five great physics websites will help you decide if a degree or career in physics is the right choice for you. My focus is on the most interesting physics taking place in that particular sport. String Theory: A branch of physics that attempts to reconcile quantum mechanics and general relativity; it proposes that elementary particles within an atom are 1-dimensional oscillating "strings" 21. The thing about empty space, you’d think, is that it’s empty. But as it turns out, things like light and electrons can’t really be confined to one state of existence—they act as both particles and waves, depending on who’s looking. The odds of a universe that we can exist in are very small, based on chance. “The only thing known to go faster than ordinary light is monarchy, according to the philosopher Ly Tin Wheedle. For example, knowing the club head speed with which to strike a golf ball isn't very useful to a golfer. You create the realities you inhabit.” ― Timothy Leary, Chaos & Cyber Culture Take a look at these cool physics videos. In this physics science project, you will investigate how far a ball bearing launched by a Gauss rifle will fly, depending on how many magnetic acceleration stages are in the setup and the ball bearing's initial velocity.… Physics Facts 32. I make an effort to explain those concepts that can be directly applied to the sport itself. Across astronomical distances, the only significant fundamental force of physics is gravity. The amount of energy contained in a particular amount of mass is determined by the conversion factor c squared, where c represents—wait for it—the speed of light. Learn the essentials of understanding physics through these instructional videos for students at all levels. Currently, it includes kinematics, mechanics, special relativity, waves, sound, electricity and magnetism. Now, this magnetic accelerator is not a weapon, but a way for you to learn a lot more about physics concepts, like momentum. What this means is that if you repeated the feather/bowling ball experiment on the moon (which has no atmosphere), they would hit the ground at the exact same time. Let’s say you’re riding in a car traveling at 60 mph. The negative impact of physics on society. And if you're a teacher, they are great for science classroom demonstrations. Speaking of things that are other things…. I encourage you to look them up, but only if you’re prepared to spend the whole day getting caught up in quantum mechanics. The world works in some really weird ways, and though you may need a PhD to understand why, you only need a sense of awe to appreciate how. Check it out Technically speaking, moving that fast would require an infinite amount of energy (and I for one don’t have that kind of juice just lying around). This list may not reflect recent changes (). Batteries. The primary branches of physics and what they cover. General relativity is a basic concept in physics that is often described using the analogy of a moving vehicle. You would be forgiven for assuming that heavier objects fall faster than lighter ones—it sounds like common sense, and besides, you know for a fact that a bowling ball drops more quickly than a feather. So what in the world is dark energy, you ask? In reality, as Galileo first realized about 400 years ago, gravity works the same on all objects, regardless of their mass. I’ll leave the technical details aside for now (it gets pretty complicated), but you can picture them as tiny, spinning, electrically-charged marbles. The E is for energy, and the m represents mass. When one object is measured, and the Schroedinger wavefunction collapses into a single state, the other object collapses into its corresponding state ... no matter how far away the objects are (i.e. If done appropriately, in-class physics demonstrations can be a great way to engage students and exhibit key concepts. Quantum entanglement is a special process that involves pairing up these particles in such a way that they become identical (marbles with the same spin and charge). Whether in cellphones, cars, torches, toys, or any other appliance, batteries act as saviors … Without you even touching it. Einstein's theory of relativity is based upon the principle that the laws of physics are the same for all observers, regardless of where they are located or how fast they are moving or accelerating. By converting our sims to HTML5, we make them seamlessly available across platforms and devices. Recent evidence shows that were the universe just slightly different, it wouldn't exist long enough for any life to develop. There are several specific theories that fall under the heading of unified field theory including Quantum Gravity, String Theory / Superstring Theory / M-Theory, and Loop Quantum Gravity. ", PASIEKA/Science Photo Library/Getty Images, Quantum Probability & The Measurement Problem, Five Great Problems in Theoretical Physics. Appliance Science looks at the cool physics of window air conditioners. Sets are such a simple and flexible way of organizing the world that you can define all of math in terms of them. In quantum theory, certain physical systems can become "entangled," meaning that their states are directly related to the state of another object somewhere else. Learning with us is an ideal choice for students to excel in physics. Einstein, who called this quantum entanglement "spooky action at a distance," illuminated this concept with his EPR Paradox. The Anthropic Principle, while intriguing, is more a philosophical theory than a physical one. Here are 32 of our favourite physics facts. Right after you wake up in the morning and start preparing for your school/office, you need an ironed cloth, and that’s where Physics comes into play. But here’s the other thing—you know from experience that things have definite forms—an apple in your hand is an apple, not some weird apple-wave thing. Focault's Pendulum reveals the Earth's movement as the globe orbits beneath it. Think of it like a camera—if it takes a picture of each photon as it passes through a single slit, then that photon can’t have passed through both slits, and thus it can’t be a wave.
