@U_4GotHow2Play @BecomingCritter Yes, unpublished, the art that doesn't make it into the paper, stuff purposely held back, trade secret, etc. Still, in some cases there are clues, particularly in intelligence applications - authors that go dark, mismatch between topic and institution ...

[Kevin Boyack @KevinBoyack]

@Jaydo2_0 @BecomingCritter It's not that there's no overlap, it's just not a primary overlap for either field.

[Kevin Boyack @KevinBoyack]

@sanadAlrashidi @BecomingCritter Short answer: citations. But, discipline-level maps are the wrong way to do it imo. With our paper-level maps (100M docs, 100k clusters), the cluster-cluster citation characteristics show the import/export patterns between topics. This is actionable.

[Kevin Boyack @KevinBoyack]

@bi02247255 @BecomingCritter Yes, indeed. I hear that particular phrase quite often!

[Kevin Boyack @KevinBoyack]

@CarlosL31742879 @BecomingCritter On the whole, from today's perspective, I'd say there is no 'central' science. Historically, one could argue philosophy. From a current enabling sense, math and chemistry are widely used in nearly all other fields, but that doesn't mean central imo.

[Kevin Boyack @KevinBoyack]

@8BOXdev @BecomingCritter CE, ME, ChE, Mat are all related to each other through citation more than they are to other disciplines. So, if we carve all of science into 12 large categories, they'll be together. At the multihundred level, they are all separate.

[Kevin Boyack @KevinBoyack]

I'd love to see those data. Like you, I suspect they exist, but probably widely dispersed, unless a company like Academic Analytics has gathered them (and then charges a huge amount for access).

[Kevin Boyack @KevinBoyack]

@KuviacM @BecomingCritter Wasn't meant to be a binary answer. Yes, there are some citations, but equipment tends to be mentioned in the text rather than cited in references. And since we don't have full text of everything, we don't track that type of usage. Wish we could!

[Kevin Boyack @KevinBoyack]

@alltopology @prismaticflow @AnnHertzz @BecomingCritter Yeah, funding is the dominant driver. Regarding career opps, it's ok. But for grad student choices, it doesn't work because (at least in the US), it's most often the professor that chooses the student, not the other way around.

[Kevin Boyack @KevinBoyack]

@jfarrow @BecomingCritter The overlay boxes are an interesting take, but I'd disagree. Most topics in the center box are concentrated in the CS part of paper-level maps. I've seen reasonable historical arguments that put philosophy at the center. Of course, this is a static map, so ...

This!

I’m not going to insist on being called a Christian.

Do I consider myself to be a Christian? Yes. Absolutely and unequivocally yes.

But, I understand that my rejection of formal Trinitarian dogma is a nonstarter for many. That’s ok. Everyone has a right to make such determinations.

This post (which will probably end up being quite long) is not a plea to be recognized as Christian, but rather an explanation of what I as a Latter-day Saint do believe about Jesus Christ.

Jesus is Jehovah. He is the God of the Old Testament and the Redeemer of the New.

It was He who covenanted with Abraham, and He is indeed the very God of Abraham, Isaac, and Jacob. He spoke to Moses through the burning bush and gave him the Ten Commandments. He led the children of Israel through the Red Sea on dry ground.

He is the creator of the heavens and the earth and all things that in them are.

He descended to earth in the meridian of time, was born of the Virgin Mary in a manger, and at the age of thirty began His public ministry.

He called apostles, ordained them to the priesthood, and taught the truths of eternity to all who would listen.

He established His church, healed the sick, raised the dead, restored sight to the blind, instituted the sacrament of the Lord’s supper and, when the time had come, endured the unbearable weight and agony of all our sins, pains, and weaknesses in the Garden of Gethsemane, a burden so heavy that even He, God, the greatest of all, trembled because of pain and bled from every pore.

He was betrayed with a kiss, mocked, and put through a sham trial at the behest of a mob.

He was denied, and made to endure it alone.

He was beaten, whipped, and scorned, made to carry a cross to calvary’s hill.

Large nails were driven into His hands, wrists, and feet, and a crown of thorns was placed on His head.

He suffered on the cross, pleading to His Father to forgive even those who were in the very act of torturing and killing Him.

Hours later, He gave up the ghost, declaring “It is finished”. He descended to the spirit world, preaching to the prisoners there while His body lay in a tomb.

On the third day He rose from the grave, being the first fruits of them that slept and assuring us all of a glorious resurrection and a knowledge that death will not lay claim on our physical bodies forever.

He showed Himself to his disciples, ensuring they knew that He was not a spirit, but rather that He had been resurrected with a perfected, glorified body of flesh and bone.

He gave commands to His disciples before He ascended to heaven, exhorting them to preach the gospel to every creature, baptizing them in the name of the Father, and of the Son, and of the Holy Ghost.

He initiated the restoration of His church through Joseph Smith, Jr., appearing first to the boy prophet in 1820, and later revealing The Book of Mormon, a sacred record of scripture that, with the Bible, testifies plainly that Jesus Christ is our Lord and Savior.

In the time since, He has led and guided this The Church of Jesus Christ of Latter-day Saints.

Jesus is an high priest of good things to come, the Great King Immanuel who sits on the right hand of His Father, crowned forever with eternal glory and all power, might, and dominion, having finished His preparations unto the children of men and offering them redemption through the shedding of His own blood.

He is the light and the life of the world, and salvation comes in and through His atoning blood and in no other way.

He is my prophet, my priest, my king and my God.

That is who Jesus of Nazareth is to me.

[Kevin Boyack @KevinBoyack]

@latterdaylaura Yes, wonderful! But I increasingly find myself going back to 3 Ne 9:13-22, and what he teaches them while it's still dark, and to the effect that this had on them. This is why they were at the temple for 3 Ne 11.

@jonnnnn234 @is_an_alt_man @BecomingCritter The undirected edge is actually the sum of the two directed edges. Also, it's not just a relationship, but the strength of the relationship because it's aggregated up from individual papers. So, it can be ranked/sorted. For structure, use of undirected edges is pretty common.

[Kevin Boyack @KevinBoyack]

@jr_mckee I'm in.

[Kevin Boyack @KevinBoyack]

@AnnHertzz @BecomingCritter This is an example of where journal-based analysis falls short. We abandoned journal-based maps after creating the one that started this thread. Instead, we do analysis based on papers, and those maps (90M papers, 100k clusters) show intersections such as those you suggest.

[Kevin Boyack @KevinBoyack]

@Wendy45569083 I don't think it's a loss of context. Once a paper/method/etc. becomes standard knowledge, most people don't cite it any longer even though they use it. So, while knowledge is incorporated, citations tend to replace older works with newer ones.

[Kevin Boyack @KevinBoyack]

True! One can trace the historical development of disciplines as you say. However, citation patterns today don't honor that history and they show a very different organization of the sciences. Not better, just different, answering different questions. Epistemology vs practice.

[Stuart Clarkson @stuartfclarkson]

@KevinBoyack @BecomingCritter It is not a perception. “Old academic notions” are actually based on the historical reality of the development of disciplines, including the emergence of science from the broader category of philosophy, through a web of decision making. You cannot simply disregard that reality.

[Kevin Boyack @KevinBoyack]

@AnnHertzz @BecomingCritter It's not so much that it's not linked. Rather, it's incorporated. There are more math-related papers in non-math journals than in math journals. Math is an enabling science. You'll see this much more in a paper-based map than in a journal-based map.

[Kevin Boyack @KevinBoyack]

And ... to answer the original question about the central science ... if the map is based on citations, then NO, there isn't one. But, if someone wants to use a different logic for ordering/linking disciplines, then MAYBE. Try it and share your findings.
