Neil deGrasse Tyson – The Tidal Force
Maybe a little late, but everything you wanted to know about the leap second. And tidal forces. And tidal lock. So much learning.
Periodic Table swells as three new elements named
What’s new? “Elements 110, 111 and 112 have been named darmstadtium (Ds), roentgenium (Rg) and copernicium (Cn).”
According to these, these elements were discovered between 94 and 96. That’s 1994 and 1996. What took so long to name them? I guess they have to verify them and also a couple people have to agree on a name. Not sure that takes 17 years, but whatever. I still feel like I’ll miss this in the future, so I’d like to be added to the mailing list. Even if there is only one message every score or so.
