The element is Thulium, I mispelled it.
So one man could do this, back in the 70's, (even with Thulium) assuming I explained what the scientist said as clearly as I could.
And just for curiousity, he also says the follow in video:
1. Samples contain almost all of the elements of the periodic table.
2. Samples contain the hard to obtain element Thulium with its secondary bands missing in the EDS spectrum.
3. Inclusions in the metal sample exhibit birefringence, which is found in non-metallic or dielectric crystals.
4. Sample examined at a magnification of 500 diameters show signs of micro-manipulation or micro machining.
Again, hope I'm accurate in this... I don't really know if that's something impressive or not.
Thanks!
