<p>
This week is an amalgamation of different topics that extend slightly beyond the scope of this course. Hopefully, you will be encouraged to pursue these topics further, at a more advanced level! </p><p>
First, we discuss the wave-particle duality of light in the context of the photoelectric effect. Similarly, electrons (massive particles) exhibit wave-particle duality, as we have seen in previous lessons. We delve into this in more detail by discussing several experiments of electron interference. </p><p>
Next, we introduce "Heisenberg's uncertainty principle," which relates the uncertainty in position and momentum with the fundamental constant [mathjaxinline]\hbar[/mathjaxinline]. We discuss this as it relates to the problem of electron diffraction. </p><p>
Continuing with the example of electron diffraction, we discuss the probabilistic nature of particle trajectories—specifically, we discuss how this probablility is related to the wavefunction that describes a particle. </p><p>
Ultimately, the quantum mechanics portion of this week's discussion culminates in the presentation of the Schrödinger equation. </p><p>
Finally, we discuss another wave phenomenonm, which is gravitational waves! We discuss what gravitational waves are, how they are created, and how they are detected. The 2017 Nobel Prize in Physics was awarded to Rainer Weiss, Barry C. Barish, and Kip S. Thorne "for decisive contributions to the LIGO detector and the observation of gravitational waves." </p>
