I got this pen today

[Misfit]

I found the nib unit that I swapped with my Kilimanjaro pen. It has a B nib. In the 10 years between the Cortina pen, and the next Mountains of the World pens including K2, Monteverde changed something with their nibs. The Cortina nib does not have Monteverde on it. Ten years later, the K2 does have Monteverde on the nib with the mountain shape as well. The Cortina nib has a flower then below it Iridium Point Germany. The 2010 onward nibs are loose in the Cortina section. The nib and feed are friction fit in the section. There is no housing. The current Monteverde method is nib and feed in a housing that screws into the section.  
 

Hmm, maybe I’ll get a Nemosine #6 stub nib from a pen, and try it with the Cortina.

Today, I received not exactly an entire pen, but a nib. A 14K Tang Moon Schrödinger's Cat nib with a heart beat separating the tines instead of a simple line.

I have no idea how well it writes (let´s hope for the best) and the pen it is meant to be installed in doesn´t even exist yet. The idea is to build a pen myself next summer (under the guidance of a professional), using orange-red ebonite from around the 1930s/1940s with fordite for the end-caps and this nib mounted on an ebonite feed to top it off.

Greetings!

Nice nib point...What do several symbols mean,please ?

Below the 14K marking you can see the Schrödinger equation: 

(On the nib, the parts of the equation in front and behind the equal sign are reversed.)

 

The Schrödinger equation is one of the basic equations of quantum mechanics.

H is the Hamilton operator.

Psi is the wave function describing the status of a particle in quantum mechanics.

i is an imaginary unit.

h is the reduced Planck's constant.

delta psi / delta t is the partial time derivative of the wave function, showing how the wave function changes over time.

 

It describes the temporal change of the quantum mechanical state of a physical system in a non-relativistic approximation in the form of a partial differential equation.

 

Below the equation, there is a drawing of the thought experiment of Schrödinger´s cat, neither alive nor dead as long as you don´t take a look (thus depicted as half alive and half dead).

Above the cat, there is a radiation sign, a hammer and a bottle of poison, depicting the experiment. The idea is that according to quantum physics, a radioactive atom which reaches its half-value period is simultanously disintegrated and not disintegrated (coherent superposition). The cat is locked in a steel chamber with a "hell machine" consisting of the radioactive atom, a Geiger counter, a hammer, and a vial of poison gas. The poison gas kills the cat when the atom's radiation, via the Geiger counter, triggers a blow from the hammer, shattering the vial. As long as nobody opens the steel chamber, the cat is simultanously dead and alive because the atom triggering the whole thing is also simultanously disintegrated and not disintegrated.

 

I would like to point out that this is just a thought experiment from 1935. No actual cats have been hurt.

Misfit-

Yafa changed nib companies 5-6 years ago for their Conklin & Monteverde pens.  Currently Jowo.  Previously Chinese junk.

@carola I love that nib! Very appropriate as Schrödinger was Austrian and I think that is the Austrian flag?

It is indeed.

Thank you for this information. I noticed the older nib on the Cortina has a rough part so I have to hold the pen right to get to the smoother part of the (junk) nib. I’m so peeved the pens won’t take the stub nibs I bought for them. It’s mighty rude of them. The Nemosine nib was loose too.

The last Monteverde Mountains of the World pen arrived today. It’s the Atlantica version, or number 3 in the series. I now have all of the Monteverde Mountain pens. Someday I’ll get a photo of all of them. I’m not sure where to post the photo though. 

[lascosas]

Congratulations!  They are attractive pens, good size.  Next you can collect Monteverde's People of the World and Trees of the World!

Maybe start a thread for photos of collections of colours? I have all the Kaweco Perkeo and Faber-Castell Hexo. 

 

Congratulations for achieving your Mountains!

That’s a good idea. Thank you.

Monteverde should like you. I have one of the Tree pens, Avenue of the Baobabs. It’s a bit big for me, and also attractive.

I've been out of the country for months, and came back to several pen packages from Japan.  I'll post a few more pens later, but wanted to start with this, 'cuse I think it is pretty funny.  I have seen several sellers on Mercari offer these old Sailor student pens, and I just thought they looked adorable, like Pelikan 10 & 20 models.  I had never seen anything to provide the scale of these pens.  So a set at a low price came up, and I bought them.

[lascosas]

Well, they are teeny tiny.  Here it is next to a #5 and #6 nib, and a Sailor Profit Jr.  I have no idea what long out of production teeny cartridge this used, but super glue to seal the end piece turning it into an eyedropper.

[Misfit]

The Sailor Student pens are adorable @lascosas

[Penguincollector]

 Those are Sailor Slim Candy pens from the 1970s, @lascosas. I have one, and can’t remember if Sailor Chalana cartridges fit, or if there’s a size slightly bigger.

    Wow, that’s awesome! Congratulations! I would love to see a post about subcollections on here, as I think there’s quite a few folks who concentrate on that sort of thing.

It would interesting to see how these compare size-wise to something like a Parker Vector.  Although I would also be concerned about being able to find a converter that would fit.

+1 would love to see your photos 👍😀
