I love this stuff! Only I can't believe they "demoted" its status from planet to what, planetoid? I wonder who might have thought of that...does seniority is worth anything these days? :)

 

In any case, I'll be following it and enjoying!

 

Cheers,

 

Bob

Hi ro63rto,

 

Is that the new classification? Why on earth....err....pluto, they come up with such names after it's been "ole plain given-for-granted Pluto" for so many centuries (?). Oh, well, never mind, I suppose they have dwarf stars and now they need to dwarf some planets too, but then I'm not to good at astronomy. It has gotten complicated in the past 10 - 20 years I guess. The way it's going, our solar system may end up as the center of the universe...the original "central theory" -- Earth central to everything -- with a twist! In any case, it would not be so far from the truth considering anything could be the center in an infinite or near-infinite space...now they're working on a near infinite number of almost infinite universes with different properties and linked somehow.

 

I'd be thrilled though if they find life or other indication of "people" out there. That would probably spice things up a bit. But I guess, as a trekkie, I can only wish.

 

Cheers,

 

Bob

According to info on NASA website its a Dwarf Planet as from 2006.

The also go on to say it's also know as a plutoid which means a dwarf planet further out than Neptune.

What I can't get my head round is the distances.

Pluto is 7.5 BILLION kilometers away from Earth. It's in our Solar System.

Our Solar System is a spec in the Milky Way which in itself is a spec in the universe [emoji50]

Absolutely. Now imagine all the galaxies that make our universe and then a near infinite number of universes! This is a quick search of what I could find but originally the idea came off the new particle accelerator somewhere in maybe Switzerland or whereabouts.

      Pivot Gauge

      By Waggy · Posted

      Could it be an abbreviation for Denier? "Denier (/ˈdɛniər/) or den (abbreviated D), a unit of measure for the linear mass density of fibers, is the mass in grams per 9,000 metres of the fiber. The denier is based on a natural reference: a single strand of silk is approximately one denier; a 9,000-metre strand of silk weighs about one gram." The pivot gauge looks interesting, however I wouldn't trust myself to drive a pivot into a wedge incase it jams and gets damaged/snaps trying to get it free. More a comment on my ability and incompetence than the quality or design of the tool 🤣

      @clockboy The damage on the movement much worse. The images against the green background are my watch the other 2 are from the internet. The rotor has erased the perlage. I am surprised how is this watch still running.

      Pivot Gauge

      By dhall · Posted

      Hi All, I recently bought a few gauges on Ebay. One of those was my actual target, a roller jewel gauge. Pictured below was one of the other gauges I received. From what I gather, this one is for measuring pivots. No sure if I'm right here. A confirmation of my assumption would be great. The gauge also has an abbreviation of "DEN". I have looked around and don't find this relative to watchmaking. Any clue to what this abbreviation means? Thanks, Don
