The Michelson-Morley Experiment | Special Relativity DeepBean 2023-03-23 | The Michelson-Morley experiment contributed to the crisis of ether theory that eventually gave way to Einstein's special theory of relativity. In this first episode of the Special Relativity series, we summarize the motivation, results and implications of that pivotal experiment.Please like, comment and subscribe if you appreciate what I do!SPECIAL RELATIVITY SERIES-----------------------------------------------I.

The Geiger-Marsden Experiments | Nuclear Physics DeepBean 2023-05-28 | In 1908-13, nuclear physics was born as Hans Geiger and Ernest Marsden embarked on the experiments that would discover the atomic nucleus and revolutionise our understanding of atomic structure. Here we explore why and how they carried out the famous gold-leaf experiment, as well as how Ernest Rutherford arrived at his startling conclusions.CHAPTERS-----------------Introduction 00:00Alpha Particles 00:20The Geiger Counter 01:13The Gold Foil Experiment 02:28The Plum Pudding Model 02:50Geiger-Marsden Results 03:22Rutherford's Conclusions 04:00The Solar System Model 05:15
Dijkstras Algorithm: Finding the Shortest Path DeepBean 2023-05-14 | Dijkstra's algorithm is a neat way of finding the minimum-cost path between any two nodes in a graph. Here we see briefly how can use it to optimize our path through a graph, and also explore why it performs as well as it does. Feel free to like, comment and subscribe if you appreciate what I do!
Einsteins Ladder Paradox; Simply Explained DeepBean 2023-05-11 | In special relativity, the ladder paradox (or, "barn-pole" paradox) occurs due to they symmetry of length contraction. Here we explore how this apparent paradox can be solved using the relativity of simultaneity.If you're interested in more special relativity content, check out the series below!SPECIAL RELATIVITY SERIES-----------------------------------------------I.

Einsteins Twin Paradox - The REAL Solution DeepBean 2023-04-30 | Many solutions have been proposed to Einstein's twin paradox, but many of them miss the vital reasons why the Earth twin is correct and the Spaceship twin is wrong. Here we condense the solution of the twin paradox to its essentials, and also discuss why applying general relativity to the problem is unnecessary.CHAPTERS------------------What is the Twin Paradox? 00:00Time Dilation 00:43The "Paradox" 01:17The "General Relativity School" 02:09Twin Paradox Without Physical Acceleration 03:31Bob's Two Reference Frames 05:04The Counterargument 06:06Why the Counterargument is Wrong 07:08If you're interested in more special relativity content, check out the series below!SPECIAL RELATIVITY SERIES-----------------------------------------------I.

What is Spacetime? | Special Relativity DeepBean 2023-04-14 | In this fifth video, we explore how space and time can be treated as one interrelated entity, and how the Lorentz transformations can be given a geometric interpretation. We also explore how paradoxes are avoided by the preservation of causality.Please like, comment and subscribe if you appreciate what I do!SPECIAL RELATIVITY SERIES-----------------------------------------------I.

Deriving the Lorentz Transformations | Special Relativity DeepBean 2023-04-03 | In this third video of the Special Relativity series, we derive the Lorentz transformations, which map events in one reference frame to another reference frame that moves at a constant relative velocity. We also demonstrate how these transformations can be used to derive the phenomena of time dilation and length contraction that we explored more informally in the last video.Please like, comment and subscribe if you appreciate what I do!SPECIAL RELATIVITY SERIES-----------------------------------------------I.
