understanding the quantum world

Professor Carlson notes that the sloshing of an electron back and forth in an unstable state causes it to act like an antenna, radiating away energy until it falls to a lower energy level. Again, a phenomenon familiar in classical physics relating to planets has an analogue in the quantum domain—although with profound differences. You must have JavaScript enabled in your browser to utilize the functionality of this website. This course is not for the uninitiated. It also analyses reviews to verify trustworthiness. Analyze how metals conduct electricity, discovering that, in a sense, electrons “surf” from one metal atom to the next on a quantum mechanical wave. I was amazed at the professor's mastery of her subject. Begin your journey into the quantum world by focusing on one of its most baffling features: the behavior of quantum entities as both particles and waves. Quantum physics is more than just a fun intellectual exercise. The other class of particles, bosons, with integer spin, can be in the same place at the same time. Quantum mechanics has a reputation for being so complex that the word “quantum” has become a popular label for anything mystical or unfathomable. Return to the Heisenberg uncertainty principle to see how quantum uncertainty also extends to energy and time. Explore the principles and paradoxes of quantum mechanics with exceptional rigor and clarity-and using minimal mathematics-in 24 episodes. Fill out the details on the next page. I especially like the illustrations and analogies to help me visualize difficult concepts without resorting to equations. Q: What if my friend or family member does not receive the email? Learn how this feature of bosons has been exploited in lasers and in superfluids such as liquid helium. In Understanding the Quantum World, Professor Erica W. Carlson of Purdue University guides you through this fascinating subject, explaining the principles and paradoxes of quantum mechanics with exceptional rigor and clarity—and using minimal mathematics. Then learn how quantum physics was born at the turn of the 20th century in Max Planck’s solution to a paradox in the classical picture of oscillating atoms. Finally, use the Pauli exclusion principle to understand the optimum distribution of electrons in the different quantum states of metal atoms. In carbon, such waves make possible several types of bonds, which in diamond and graphene result in remarkably different physical properties. As usual, Professor Carlson introduces useful analogies, including the standing waves produced in a vibrating drum head. See how the diverse possibilities create a “fingerprint” specific to every type of atom, and how this is the basis for spectroscopy, which can determine the composition of stars. Bizarrely, the wave properties disappear when the electrons are monitored as they pass through each slit, showing our inability to have complete information of a quantum state. For instance, there would be no trouble sitting in three chairs at once! Privacy Policy. In fact, quantum mechanics is one of the most successful theories of reality yet discovered, explaining everything from the stability of atoms to the glow of neon lights, from the flow of electricity in metals to the workings of the human eye. Ability to download 24 video lectures from your digital library, FREE video streaming of the course from our website and mobile apps, loc_en_US, sid_9750, prod, sort_[SortEntry(order=SUBMISSION_TIME, direction=DESCENDING)]. See how electrons behave as both particles and waves when passing through two parallel slits in a plate and then striking a screen. Quickly browse titles in our catalog based on the ones you have picked. Interference of Waves and Sloshing States. A clock pendulum is an example of a classical harmonic oscillator. Also investigate the source of color blindness, most common in men, as well as its inverse, tetrachromacy, which is the ability to see an extra channel of color information, possessed by some women. What now? Please enter a password that is between 5 and 20 characters long. Learn what happens when a particle in such a mixed state is forced by measurement to assume a definite position: a situation known as wave function collapse. #History. With the guidance of Professor Erica W. Carlson, you’ll get a fundamental understanding of major breakthroughs in the field (and who made them), experiments that demonstrate quantum phenomena, and quantum theory’s many applications and insights. Electrons don't just orbit the nucleus—they simultaneously exist as standing waves. Her examples were very helpful to understanding what is an weird quantum world. Q: Oops! Surprisingly, the stability of our everyday world rests on uncertainty at the quantum level. Some of it I understood, but this course has really opened my eyes and her examples have done a fantastic job in allowing me to understand some of the basic and more complicated concepts and the strangeness of the Quantum world. Q: Can I return or Exchange a gift after I purchase it? Look for exclusive offer emails and new course releases from The Great Courses! You will begin Understanding the Quantum World by covering the central paradox of the field: the wave-particle duality of matter. An email will be sent immediately to notify the recipient of your gift and provide them with instructions to redeem it. Continue your investigation of the counterintuitive quantum world by contrasting angular momentum for planets and other classical objects with analogous phenomena in quantum particles. We use cookies and similar tools to enhance your shopping experience, to provide our services, understand how customers use our services so we can make improvements, and display ads. Investigate why two pieces of matter cannot occupy the same space at the same time, reaching the conclusion that this is only true for fermions, which are particles with half-integer spin. Q: What if the email associated with eGift is not for my regular Great Course account? Among Einstein’s insights was that light comes in discrete packets of energy called photons. Examine this idea and the experiments designed to test it. Take a closer look at the philosophical implications of quantum mechanics. The recipient already owns the course I gifted. Investigate one of the most famous demonstrations in physics: the double-slit experiment. Bell’s theorem shows that attempts to reconcile the two systems are futile in a certain class of theories. Watch what happens when electrons are put into wave forms that differ from standing waves. Because the gift is sent immediately, it cannot be returned or exchanged by the person giving the gift. Look at the Copenhagen interpretation, Einstein’s realist view, the many worlds interpretation, quantum Bayesianism, non-local hidden variables, and other creative attempts to explain what is going on in a realm that seems to be governed by probability alone. Professor Carlson uses a roller coaster analogy, combined with your newly acquired insight into wave mechanics, to make this feat of quantum sorcery (the equivalent of walking through walls) perfectly logical.

This experience is optimized for Internet Explorer version 10 and above. Travelling or based outside United Kingdom? Understanding the quantum world. Is quantum mechanics an incomplete theory due to hidden variables that guide the outcome of quantum interactions? Then head into space to learn how GPS satellites use atomic clocks to triangulate positions on the ground. Quantum Wave Shapes and the Periodic Table. Hauptseite Understanding the Quantum World.
