I love to use you videos in the chemistry class I teach (high school).

However, from this page I can not access the videos.

How to?

David,

I found your website while preparing for my college course ‘Materials and Processes’. I plan to use the beryllium clip for my class and look forward to viewing subsequent editions. Your format is very engaging utilizing many resouces and ‘grabbing’ the student’s attention with several ‘hooks’. I have used similar techniques to much success in my PowerPoint presentation for adults.

I hope to hear from you and find the rest of your students’ work on this subject.

Nice work on beryllium production! You might consider a series on the rare earths, as they combine the glamor of ultra-high tech applications with interesting geopolitical facts (I’ve heard the Mountain Pass, CA mine will reopen soon: maybe they’d fund it? Apparently they have similar environmental issues, namely uranium & thorium byproducts that have to be dealt with before mining recommences……)

I saw some Feynman Diagrams in your intro Do you know how to read them? I copied them from the Feynman VAN but haven’t been able to find anyone to interpret which rxs they are?

I’m listening to the Arsenic (may have caused Dad’s Prostate Cancer…?) When I was researching the essential elements (for humans) I found that Arsenic can be considered to be one (one macrophage used it to bust up foreign bacterial cell walls (but I got he impression it wa a substitution for another element since it was found that a tungsten contaminant was in on this bacteria experiment or something….) my question is “WHY IS ARSENIC POISONOUS?” I asked a BioChem Prof at Sonoma back in 1995 and he just gave me an “I don’t know?” All I could find was maybe the substitution for aP in a ATP chains (thus mitochondria get damaged…

But is a mutagen I guess? gets into the nuclear membrane?????

Dear David V. Black
My wife and I just saw your video about the periodic table and of your project and we have amazed, because I am studying this issue for many years.
For your information I enclose some of the work done, one is on the work of Oswaldo Mendoza Baca (1908 – 1962), Peruvian scientist who sought to find mathematical functions that explain the periodic table in 1953, whose work we have uploaded on You Tube at the following address.

Also I am entrusting my work ¨Periodic Harmonic Table, published in Spanish in 2006.

and finally a video on my proposal Telluric Helix as development Chancourtoix thruster, which, due to limitations of the software, we could not put symbols of the elements.
NDA of the Materia or the Gutierrez Samanez telluric screw

My best wishes to you.

David,
I found your blog by reading through another blog which had an entry on the value of the iPad. (I was surfing around looking for opinions on iPad). I was intrigued by your comments on that blog regarding this Elements Unearthed project. I will definitely be viewing your videos. I myself have biochemistry degree, so I already have an affinity for the elements. Currently I am homeschooling my three young boys and this will definitely go on my resource/ “to-do” list. I haven’t watch any of the videos yet, so it’s possible that my boys are still a bit young for it, but what a neat project. THIS is what is so fantastic about the Internet. Thanks for all your hard work.
Catherine
