@clayton & Tucker, great job guy's and thanks for the great effort you are pulling trough
And bcavnaugh, thanks for the table. Genious to Place it here in this setting

Way back, this table was made by scientists (of corse) but the story on how, and by whom, and again, how it got acnowledged..... is quite some story

Back then, science had less documentation, it was more about influence in the right sosieties, so this table took some time to get established.
In Einsteins early day's, he was not established in the right sosiety, and was even looked at as an outcast, and of some, a radical without any true knowledge. The E=mc was acnowledged many many years after he published it.
Oops, riding towards off topic

Anyways, not sure if Einstein had much about the elementals, probably nothing....

As said, just me fading away

Thank's bcavnaugh
