Thanks to our high-speed DSL, I am able to look at as many as I want. It would be really great to see a live display.</p> <p>When I first started reading the description and noticed that they had actual samples in the display, I wondered how they contained the radioactive ones. Then I clicked on a few - they just have a radioactive symbol and they say &quot;if we had an actual sample here, you would be dead.&quot; (:</p>tag:sursumcorda.salemsattic.com,2018:/isso/31/992005-02-21T14:54:20ZDSTB<p>What a beautiful display. It would probably be much more effective in getting kids interested in chemistry than the mere memorization of the periodic table. All I remember about chemistry are the letters s, p, d, f which is what my high school chemistry teacher basically yelled at us over and over again after a particularly bad showing by most of the class on one of her exams.</p> <p>I checked out Radium on the table (I would have done more, but the download is fairly long). It reminded me of a story I heard not too long ago. Radium based paint was used to decorate clock faces because it would glow in the dark. The women who painted the dials were paid by the dial and to speed their pace would often stick the tip of their brush into their mouth to form it into a sharp point. Many developed cancer and died, the bones in their jaws disintergrating.</p>
