Apparently, Theodore Gray has a sample of polonium deposited on gold foil. Does this look real? If the container holding it broke, or even worse, you touched it, would you be in serious danger given the lethal dose is around 50 nanograms? Finally, wouldn't this sample not last very long given the half-life of 138 days?
I recently got a PAMP Lady of Liberty bar which as a very nice shiny finish. I'm considering getting an American silver proof coin as well. Will the coin look noticeably shinier and more impressive than the bar?
Also, I would like to take out the proof coin so I can view it without the capsule. Is it easy to do so?
I recently took an assessment that used the HackerRank Desktop App. The app has very strict proctoring, requiring all other applications on the computer to be closed. It also requires a constant camera view and screen sharing. Can any tools bypass the proctoring in this application, or is it completely secure?
I'm thinking of getting a cube, probably 1 inch or 2.5 cm long, plated with osmium metal. The plating will probably be a few microns think. Would this cube be safe to handle if I want to regularly touch it? Will small amounts of osmium scrape off, and would they form dangerous amounts of toxic OsO4?
I have a BU silver coin that I just put into a Saflip coin flip. However, I want to keep it shiny long-term and minimize tarnish. Is it better to get a capsule such as Air-Tite to hold it, or is the flip good enough?
Is this recording here the original instrumentation of Gossec's Gavotte from Rosine? It's a famous piece often played by beginners, such as in Suzuki books. It has been arranged countless times, but I'd like to hear the original. What are the best recordings of the original gavotte?
Does anyone have a France BU Mint Set, such as the one here? I want to get one, but I also want to take out the coins and put them in my own binder. How easy is it to take out the coins; will I need a knife to do so?
