    <content type="html">&lt;p&gt;I agree that the reference to the degree should be as it was awarded, but unfortunately there's no way to do that currently with Freebase.  The link is symbolic and the name at the end of the link is used universally for all occurrences so you can't have Artium Magister one place and Master of Arts another.  The are occasional places in the schema where the actual value is preserved (Book Edition &quot;credited as&quot; for authors comes to mind), but when a literal string is used like that you lose the power of the symbolic connection.  There isn't yet a good way to have your cake and eat it too.&lt;/p&gt;</content>

    <content type="html">&lt;p&gt;The standard practice in Freebase is not to create multiple topics for things that are identical except in name, so the practice with degrees has always been to use the same degree topic, no matter how called by the granting institution at the time. Thus degrees of &quot;Artium Magister&quot;, &quot;Master of Arts&quot;, and &quot;M.A.&quot; are all represented by &lt;a href=&quot;/view/en/master_of_arts&quot;&gt;http://www.freebase.com/view/en/master_of_arts&lt;/a&gt;.  Or, in other words, the name isn't as important as what it represents.  Hence, there is also some variability on how the degree topics themselves are named, based on whatever the user who created (or renamed) the topic entered. (E.g, &lt;a href=&quot;/view/en/bachelor_of_arts&quot;&gt;Bachelor of Arts&lt;/a&gt; vs &lt;a href=&quot;/view/en/master_of_arts&quot;&gt;M.A.&lt;/a&gt;)  I'd personally support expanding the names, since it's less ambiguous that way, but as long as aliases are entered for variants, they'll still show up for autocompletion and reconciliation, which is the most important thing.&lt;/p&gt;</content>

    <content type="html">&lt;div&gt;&lt;p&gt;Some institutions use, or have used &quot;the Latin degree names, such as Artium Magister (AM) or Scientiæ Magister (SM).&quot; Though the wikipedia gives examples of institutions that currently use these names, &quot;Harvard University, the University of Chicago, MIT and the University of Pennsylvania use the degree abbreviations A.M. and S.M. for some of their master's degrees.&quot; it does not say what institutions have used them in the past.&lt;/p&gt;
&lt;p&gt;I suspect that the use of such names was much more popular in the past and many bio's list degrees as such.&lt;/p&gt;
&lt;p&gt;See, for example: &lt;a href=&quot;/edit/topic/en/john_erskine_1879&quot; rel=&quot;nofollow&quot;&gt;http://www.freebase.com/edit/topic/en/john_erskine_1879&lt;/a&gt;&lt;/p&gt;
&lt;p&gt;My question--yes, there is a question--is:
how should degree information be entered?&lt;/p&gt;
&lt;p&gt;As awarded, or as known today? I think it should be as awarded, but I'd like to see a mapping to the current nomenclature, which I suspect exists, but I can't see in action.&lt;/p&gt;
&lt;p&gt;Additionally, I'd like to see more discussion of this in the help text, right now it just says to enter info about the degree:
&lt;a href=&quot;http://rookery5.aviary.com/storagev12/2678000/2678399_95c4_625x625.jpg&quot; rel=&quot;nofollow&quot;&gt;http://rookery5.aviary.com/storagev12/2678000/2678399_95c4_625x625.jpg&lt;/a&gt;&lt;/p&gt;
&lt;p&gt;It should give instructions as to how to enter the degree:
In the original form.
In fully qualified format and not an abbreviation.
...and other stuff&lt;/p&gt;&lt;/div&gt;</content>

    <content type="html">&lt;div&gt;&lt;p&gt;I've added particle family to the particle type so I think we can now drop particle statistical family and group. I've also engaged in some property reciprocation.&lt;/p&gt;
&lt;p&gt;Self antiparticles: ugh. The double links solution is pretty horrible. The only other solution I can think of would be to have a &quot;self antiparticle&quot; boolean, but that's probably even worse.&lt;/p&gt;
&lt;p&gt;Composition of π⁰: in slight handwaving terms, the π⁰ can be thought of as alternating between being composed of (an up quark and an up antiquark) and (a down quark and a down antiquark), but never (an up quark and a down antiquark) or any of the other combinations. The only ways I can see to model this either end up with CVTs inside CVTs or creating a topic for something like &quot;composition of the π⁰&quot;.&lt;/p&gt;

    <content type="html">&lt;div&gt;&lt;p&gt;&lt;strong&gt;Self antiparticles&lt;/strong&gt;: There isn't a way to set a particle to be its own antiparticle using a sibling-relationship CVT -- the CVT has only one property to hold both particles, and you cannot enter the same topic as a value for a property more than one time.  The only work-around would be to use something that resembled a phylogeny pattern, with two linked properties &quot;antiparticle&quot; and &quot;antiparticle of&quot;. This is kind of ugly, but would handle the π⁰ case. The problem with this pattern is that you have to enter all the relationships in twice for all particles that aren't antiparticles of themselves -- once in the &quot;antiparticle&quot; property, and once in &quot;antiparticle of&quot;.&lt;/p&gt;
&lt;p&gt;&lt;strong&gt;Composition of π⁰&lt;/strong&gt;: I'm not sure what &quot;linear combination of (up-antiup) and (down-antidown)&quot; means, but I can see in Wikipedia's &lt;a href=&quot;http://en.wikipedia.org/wiki/List_of_mesons&quot;&gt;list of mesons&lt;/a&gt; that there are several mesons with similarly complex compositions. &lt;/p&gt;
&lt;p&gt;&lt;strong&gt;Uncertainties&lt;/strong&gt;: we can do this -- see how we handled it for &lt;a href=&quot;/type/schema/chemistry/atomic_mass&quot;&gt;atomic masses&lt;/a&gt;.&lt;/p&gt;
&lt;p&gt;&lt;strong&gt;Spin&lt;/strong&gt;: Agreed -- let's make it just be a float for the particles. We can refactor the Particle Spin type separately.&lt;/p&gt;&lt;/div&gt;</content>

    <content type="html">&lt;div&gt;&lt;p&gt;More from me... it doesn't at the moment to seem possible to set a particle to be its own antiparticle (try it with the &lt;a href=&quot;/edit/topic/guid/9202a8c04000641f8000000012355527?domain=/user/lukeschubert/default_domain&quot;&gt;π⁰&lt;/a&gt;). Any thoughts on a way round this one?&lt;/p&gt;
&lt;p&gt;Also, we need to find a way to model the composition of the π⁰, which is a linear combination of (up-antiup) and (down-antidown).&lt;/p&gt;
&lt;p&gt;I'll shut up for a bit now and let other people get a word in edgeways :-)&lt;/p&gt;&lt;/div&gt;</content>

    <content type="html">&lt;p&gt;Two more thoughts from the way to work: do we want to include uncertainties on properties like mass, etc? Also, I created a &lt;a href=&quot;/view/en/hadron&quot;&gt;hadron&lt;/a&gt; type to model the composition of baryons and mesons.&lt;/p&gt;</content>

    <content type="html">&lt;div&gt;&lt;p&gt;Yes, it would allow people to enter the class as &quot;fermion&quot;. If we really wanted to avoid that possibility, we could have &quot;particle family&quot; type (quark, gauge boson, meson, etc) which link to a &quot;particle class&quot; type (fermion, boson, hadron), but that seems to me to be to getting towards creating types for the sake of it.&lt;/p&gt;
&lt;p&gt;Spin: just a floating point number, yes. The particle spin used in chemistry is the same concept, but it's typically expressed in a different way.&lt;/p&gt;
&lt;p&gt;In other news, I've created the particle &lt;a href=&quot;http://particlephysics.freebase.com/&quot;&gt;[physics bas](http://particlephysics.freebase.com/)e&lt;/a&gt; and added the &lt;a href=&quot;/view/base/particlephysics/particle_family&quot;&gt;particle family&lt;/a&gt; type. Luke, you're an admin so you can move your types over there if you want.&lt;/p&gt;&lt;/div&gt;</content>
