I don't think the "market" is going to like the way the Trump administration handled the immigration problem: futures for Monday morning are now down 80 points. The "market" was looking for a reason to take profits.

A Note For The Granddaughters

"The Planet That Wasn't There," Thomas Jones, London Review of Books, essay re: The Hunt for Vulcan: How Albert Einstein Destroyed a Planet and Deciphered the Universe, Thomas Levenson.

Link here. 

Two pages long, this article seems to be divided into four parts:

• the current search for another planet in our solar system;
• how Neptune was discovered;
• the search for a planet situated between Mercury and the sun (apparently does not exist); and,
• how Einstein explained Mercury's erratic behavior.

I'm posting the note because I'm interested in the first "part": the current search for another planet in our solar system:

• primary researchers: California Institute of California, Konstantin Batygin and Michael Brown 
• five dwarf planets
• Pluto (August, 2006, went from a planet to a non-planet to a dwarf planet)
• Eris 
• Haumea
• Makemake 
• Ceres: the largest body in the asteroid belt between Mars and Jupiter; the other four are beyond Neptune 
• the search is being done primarily using the Subaru telescope on Hawaii
• the search is expected to take six years
• the "planet" is going by the name, "Planet X"
• "Planet X" is suspected because of the highly elliptical orbit of Sedna
• Sedna: a "short-period" comet that originated from the Kuiper belt (disc) beyond Neptune

This is the kind of stuff that would have fascinated me in high school. It still does, but perhaps not as much.
