How can you tell a construction worker from a chemist? Ask them to pronounce 'unionized'

"The thinking mind must constantly be stirred by new experience and by adaptation to new experience and new understanding in order to be vital and capable of learning. It is like stirring concrete. If you do not keep stirring it and adding water and new things to it, it hardens. And once it hardens, it can only be broken. People who are learning and living The Way of Knowledge are constantly being renewed and refreshed because they are close to life, and they are close to Knowledge. Their thoughts change, grow and evolve. Their ideas change, grow and evolve. Their conclusions change, grow and evolve. They can do this because there is something greater. There is Knowledge, the dynamic force of life within you, within the world and within the Greater Community as well. Knowledge brings you to the edge of life where you have to learn and adapt, communicate and contribute. This keeps you young, alive and close to the heart of life. Your mind, then, becomes constantly relevant to the present and is able to prepare for the future." This is a quote from a book titled Living the Way of Knowledge. For those who wish to educate themselves about the human mind, about the deeper spiritual intelligence within each person, about the meaning and purpose of life, about the great changes happening in the world and even greater yet to come, about the Greater Community of intelligent life in the universe, you can read this book free online, among many others at *NewMessage org*

[@bryanseare2704]

@@160p2GHz i highly doubt that they do. General chemistry is a prerequisite to organic chemistry, and high school chem classes are way easier and not as comprehensive as general chemistry i took in college. If they do, they either dumb it down, or have a college level professor come host an ap class for people that already took ap general chem.

Odd that you purposely didn't credit Watson and Crick by name but you made sure to mention Franklin... All 3 scientists were equally as important. Of course we have to include the woman who's work wasn't credited for decades but excluding the men is not equality!

[@fionafiona1146]

They weren't tho. She had the imaging skills and wrote about the helix while the men were bullying and still writing letters about "news" that were false interpretations.

[@tonyhart97]

Their names were literally on the paper that the video showed but the commentary didn't mention their names.

[@prahjex2501]

@@tonyhart97 - I'm curious about your comment. After she talked about five men and one woman, can you explain why you feel that the one woman-and not the five men-was included in exchange for Watson & Crick? Nevermind that W&C were still prominently featured in the video and the footnotes, or that Rosalind's work in particular was foundational to W&C's work. I'm confused about why you feel there is somehow an issue of exclusion and equality here.

Has Chemistry education changed in the last 40 years? I learned that Carbon has 2 P sub-orbital valence Electrons in the second electron shell and is missing 4 more electrons to complete the sub-orbital. Here's how I was taught: - Carbon has 6 electrons - The first electron shell is a S sub-orbital only which is complete when it has 2 electrons - The second is an S and a P sub-orbital which is complete when it has 6 electrons. - The S sub-orbital will complete *before* the P sub-orbital will take electrons. - The second electron shell in Carbon has a complete S sub-orbital, and a P sub-orbital with 2 electrons seeking 4 more electrons to make the completion. Has this knowledge been abrogated?

The animators of these contents deserve a big salute but the teachers a middle finger!!!They are just telling who did this ,when he did this most of the time giving less time to the concept what we actually need.They have been working on these things for their entire life but almost all of us watching this are new to this.I understand this stuff,but not deeply ,because they just introduce unrelevant things,this topic was to be corely focused how molecules actually look at a deeper level,the animations are the only reasons to watch these videos .Einstien said,"If you cant explain the thing you know to a 6 year old,then you are actually either showing off or not getting yourelf". These people have understood no doubt for their life is just rumbling around these things and they fall into the second category of einstien's saying

[@tpstrat14]

ok so the way I see it is that this is just above the abstraction level of quantum theory. In other words, it’s the smallest you can go before stuff gets REALLY weird (where particles pop into and out of existence according to probability)
