Quantum Theory Made Easy [1]

Published on Jul 17, 2015
“Quantum Theory Made Easy,” a series in which the concepts of quantum physics are broken down for layaudiences in a more digestable manner. More in-depth than most presentations for laypersons, but without the mathematical rigour needed by a specialist in the field.
So, you've heard that light is a wave/particle. Now you get to find out how we know this!
In this episode, we’ll be discussing the dual nature of light, starting with a brief overview of how light was determined to be an electromagnetic wave and what properties light was classically associated with. From there, we’ll present the results of Planck’s blackbody experiments and introduce the concept of quantization, which was how this whole quantum mess was started in the first place. After explaining how the quantum of action (h) works, we’ll move on to how it showed up in experiments that challenged the wave picture of light, and how Einstein, bremsstrahlung, and Compton, made it clear that light can behave like a particle.

How memories form and how we lose them - Catharine Young

Published on Sep 24, 2015
View full lesson:

Think back to a really vivid memory. Got it? Now try to remember what you had for lunch three weeks ago. That second memory probably isn’t as strong—but why not? Why do we remember some things, and not others? And why do memories eventually fade? Catharine Young gives the basics on memory and memory loss.

How Quantum Biology Might Explain Life’s Biggest Questions | Jim Al-Khal...

Published on Sep 16, 2015
How does a robin know to fly south? The answer might be weirder than you think: Quantum physics may be involved. Jim Al-Khalili rounds up the extremely new, extremely strange world of quantum biology, where something Einstein once called “spooky action at a distance” helps birds navigate, and quantum effect

האחים אשל ועובדיה חממה - אנא בכח

בשנת 2006 הלחין עובדיה חממה את פיוטו הנודע של ר' נחוניא בן הקנה "אנא בכח" וכך הנגיש אותו לקהל גדול שלא הכיר את הפיוט קודם לכן. את העיבוד המחודש מבצעים האחים אשל בתכנית "אבן גבירול פינת יהודה הלוי" של הטלוויזיה החינוכית שהוקדשה לפיוט הקבלי
