Parker Is Performing Flawlessly; Withstanding 2,500 Degrees Fahrenheit At Perihelion...


It was within 15 million miles of the sun on that pass -- and all went perfectly (23 more passes to go!):



Now you know. Onward, and thank you, Professor Parker.

on a different topic but still science:

"This is fine when it comes to measuring a bag of sugar, but is becoming unacceptable for more sophisticated science, such as when measuring doses in pharmaceuticals," a statement from the NPL said.


I love science....

Excellent find, Anon. Truly!

And (forgive me because I will not double check this via Google -- rather just write it "off the top of my head"!) now. . . it is doubly fascinating that the "new" kilogram is measured using two constants which, near a black hole. . . are no longer constant.

So the "Plank Constant-derived approach" works flawlessly everywhere on Earth (and essentially in perpetuity throughout our stable solar system), AND inside all of our local group of stars. . . but will (IIRC) per force break down, as we near an event horizon/black hole somewhere "out there".

[I suppose to be fair, the "old school" hunk of inert metals would be so severely squished, near a black hole, that billions of electrons would fly off of it, and thus likely shed significant amounts of mass, as well.]

But my rather whimsical (yet Hawking-verified as real) notion is that. . . any "kilo" calculated by multiplying the speed of light times any Plank constant derived equation. . . will also per force decrease, as the speed of light decreases, very near the event horizon -- until it stops entirely -- at that horizon point.


Okay -- I need to lay off the real root beer, after nine PM. Grin!

G'night!

Smile. . . yep -- and only 12 days until a (hopefully) soft touchdown, by Insight, on Mars. . . followed by some robotic "Martian mining" -- at least a dozen meters deep. Truly white knuckle theater from JPL and NASA.

Onward. [And thanks, as in my family of origin -- there is no higher compliment than "geek".]
