This is a playlist of Crash Course World History which I like a lot. The funny author John Green (ya, the one who wrote “The Fault in our Stars”) will teach you the history of the world in this 42 episodes of Crash Course, which covers all the important civilizations, empires, wars, and revolutions the world has seen so far.
This series of video is also hosted in Khan Academy https://www.khanacademy.org/partner-content/crash-course1/crash-course-world-history
A nice article I came across “10 Totally Mindful Mantras from Totally Awesome 80’s Movies!”
Personally like #1, #5 and #7 the most:
1. “Nobody puts Baby in a corner.” (from Dirty Dancing)
This one reminds me of the famous Eleanor Roosevelt quote: “No one can make you feel inferior without your consent.”
No one can put you in a corner you don’t want to be in. You are in control. But…
5. “I’ll be back.” (from The Terminator)
Because everything will be back, even shoulder pads, apparently (gag me with a spoon!). Everything is fluid and ebbing and flowing and shifting and changing. Sadness will visit again. Happiness will visit again. It’s the human (and cyborg) condition.
7. “How many of them really know what they want, though? I mean, a lot of them think they have to know, right? But inside they don’t really know, so… I don’t know, but I know that I don’t know.” (from Say Anything)
It’s okay to not have all the answers. No one does. I mean, did any of us everactually solve the Rubik’s cube? Lovable Lloyd Dobler is clearly channeling Socrates as he rambles. Socrates said, “True wisdom comes to each of us when we realize how little we understand about life, ourselves, and the world around us.”
Be mindful of what you don’t know. Be open and aware so that you may learn more.
Miss out this important video on Relative Atomic Mass (or called “weighted mean mass”).
Note: let’s learn this new vocab in chemistry context before we proceed with another video on “How to calculate the Relative Atomic Mass”:
abundance – The amount of an isotope of an element that exists in nature, usually expressed as a percentage of the total amount of all isotopes of the element
This shows how centrifuge works:
Another one, explaining Chromatography:
And in the below video, it explains what is Retention factor (Rf) and what does it tell about the solubility of a separated component.
