An apology (a defense) of the {e}vangelical

 When I was in college, I had a conversation with a friend that became centered on the label "evangelical" among Christians.  I vaguely remember his expression as being somewhat cynical, perhaps a little amused, over some shortcoming of this group of people with whom he did not seem to identify closely, though we were also both believers.  Having little context and almost no sense of the baggage that was associated with the term (I don't really remember hearing it much before college), I readily claimed "evangelical" as applying to myself.  The word "evangelical", I argued, was a descriptive label, intended to connote what Christians were supposed to be doing any way - spreading the good news that in Jesus, God made a way for everyone who would come to Him to be saved. Matthew 28:19-20 of the New Testament records a direct command to all of His followers to go and tell everyone, everywhere about Him. A Christian, I argued, was supposed to be inherently evangelical.  He ceded my point, seemed to admire it, even, and I felt that I had carried the day.  

I still believe that these things are all true, but I also believe that in this instance (as well as a few others) I might have been overly reliant on grammar and my understanding of English diction.  What I interpreted as an adjective had, and continues to have, pretty strong connotations for various streams of Protestant theology, and over the last many years, has morphed even further into a cultural label that carries a lot of weight in both religious and political circles. 

I was raised in the church and became a Christian at a young age.  Through God's grace, there has been a legacy of faithful, praying believers in my family.  I grew up in an area where belief in God was usually assumed and a baseline level of respect for God and clergy was pretty universal.  My views were formed by both a high view of Scripture and a lot of Christian media (books, tapes, CDs, TV, DVDs, music, preaching, news shows, movies, church,  - all of it)  in daily life, due to my parents and much of my extended family.  There was also an emphasis and an encouragement for me and my siblings to read, memorize, understand, and apply Scripture for ourselves.  These things were coupled with a strong view of education and learning, and encouragement to read widely.  If God's word was true, then it was the basis for everything good in life, and there would be underlying themes of consistency, reason, reconciliation and truth throughout all things, mystery notwithstanding. 

As a result, my biblical views (my views on the Bible as God's word and the basis for life and action) were pretty soundly based in Scripture, but did not conflict with most of my views of culture or with my academic studies.  When my views were challenged, they were usually challenged in fairly controlled circumstances.  We were "nondenominational" with some Baptist and CoCDoC family history and apostolic and pentecostal leanings, and had attended a few different churches by the time of my adolescence,  so (perhaps in conjunction with my youth) I didn't have a lot of language for things like catechisms, denominations, systematic theologies etc.  So while this gave some room for inquiry and resilience or openness, my views were also sometimes sheltered, often idealistic, and carefully held.  

My friend was from a rather different set of church traditions. He had experienced different family circumstances within those traditions, which had shaped his views.  As a young adult, he had strong interests in ministry training and theology.  Some of our other discussions, which would occasionally refer to topics like predestination and soteriology and his wrestlings with the implications of those teachings, remind me now that these were also the days of the Neo-Calvinist "young and restless", when the debates between various Christian groups reformed and otherwise and even secular apologists were probably as lively and plentiful as they are today.  Regardless of his background, as someone who aspired toward pastoral ministry, he was probably involved in many of those debates.

My friend, who was a conservative, orthodox, Christian believer, and a sincere student of scripture, was also black.  Without drawing too many conclusions in hindsight, or painting with too broad a brush, I suspect that in that world of argument he had already begun to see at the ripe old age of 20 that instead of being used to name the human heralds of what is literally the best news the world has ever heard, the word "evangelical" now brings connotations less about orthodoxy and more about struggles for power involving politics, class, and racial constructs with and within Western Christianity.  The term "evangelical" has often been folded into a set of ideologies that have little to do with Scripture and seems to be increasingly claimed by people who don't even hold to historic biblical Christianity2.   I believe that the resulting ambiguity has been detrimental to the reputation of believers in the US.  The Bible speaks of Satan being the author of confusion, and it certainly seems as though the adversary uses it to advantage.

Because of the circumstances of my upbringing, I don't have a strong sense of identity wrapped up in the specific word evangelical, but I have a very strong sense of identity wrapped up in the way that people who claim the name of Christ represent him in the public sphere.  So when people make claims against the "evangelicals", and sufficient confusion as to who evangelicals actually are results in damage to the Christian witness, I am now involved.   And I believe that there are time when true believers are called upon to correct the record of what God has actually said.  

So.  I don't have to go around calling myself an Evangelical, but I am evangelical, and abandoning the term seems unlikely to accomplish anything useful in the end.  Perhaps by persisting in the use of the word in its original context and standing firm in our convictions, I and other believers can add a tiny modicum of balance to the ongoing conflicting narratives in these ending days.

I don't think I have to be the one to speak about everything on every topic.  Plenty of people already have plenty of good things to say, and often times there is plenty of publicity without my wading in.  But occasionally, if the Lord so leads, it might be time for me to say something or amplify the voice of others. 

In the introduction to Evidence That Demands a Verdict", author Sean McDowell argues that one of the reasons that apologetics is important today is that the practice of apologetics helps shape culture1.  So many times, we hear of apologetics as debates and arguments between "science and faith", or between Christianity and athiesm or other religions.  I would argue that if we are really interested in the shaping of culture, the category of apologetics is broader than people realize.  Any time Christianity confronts some unredeemed focus of the human heart - an idol - it is functionally similar to a religion, and apologetics can come into play as an argument for and defense of the Christian viewpoint on that topic.  In this sense, I would argue that the work of some abolitionists (Frederick Douglas, for example) and civil rights leaders (some of the work of MLK Jr), and even of some cultural, class, and economic commentators will fall into this category.  I would also argue that it is not sufficient to ignore or discount real-world implications of the Bible on topics of leadership, decision-making, and cultural norms, and how those decisions and norms affect people who live under them. 

So.  It looks like however we describe ourselves, if we are in Christ, we are called upon to give a defense for the hope that lies within us, in whatever context, and at such a time as this.  And in doing so, we are carrying out the evangelical mission to spread the good news and baptize people in the name of the Father, His Son, and the Holy Spirit who lives within us.

I once posted a question on social media whom I found to be a thoughtful Christian leader how he found his voice despite a personal inclination to remain in the background.  A few days later, I saw a tweet that I believe to be his response: 

I decided that it was much easier to be myself and if people didn't like me, then I trusted God to bring people into my life who did.

A Christian and a Physicist

I recently gave a couple of talks summarizing some of the work that I do as a nuclear-particle-astrophysicist (name perpetually under discussion) and the impact that the Bible has had on me as a I approach and think about my work.  The talks were given to fellow believers in ministries where people were likely to be or be relationally close to scientists in their everyday lives.  On the last slide, I included a list of things that fellow Christians might consider praying for believers who are scientists.  Many of these things apply to wider academic fields, and indeed, the body of Christ at large.  
  • Boldness
  • Humility
  • Encouragement
  • Rest
  • Creativity
  • Integrity
  • Fearlessness
  • Wisdom, understanding, knowledge
  • Love for fellow believers and fellow scientists, colleagues
  • ***A desire for God’s glory
  • *Opportunities to witness faithfully
  • Protection (spiritual, physical, emotional, financial, reputation, professional, etc)
  • To find their identity in Christ
  • Balance
  • Discernment; including the collaborations they form, the projects they choose, where/how they gain/accept funding, how they present their work, and how their work impacts people, places, and the future
  • To be led by the Holy Spirit in this as well as other areas of their lives

Hello Again

I am sitting here with a deep desire in my heart to use this blog to excite and inspire people like me who love Jesus or want to want to love Him better, and who get excited by numbers and patterns and stars and nature.  I am also sitting here realizing how much time has lapsed since I started this blog and since the last entry labeled "Part I" that was supposed to be the lead-in to something that never really got expressed.  I have a lot of words and ideas and the desire to pursue them all is sometimes quite the challenge to reign in.  

Irregularity aside, I hope that those who come across this blog will find something that they can enjoy.  This post is a first step in my intent to start again.  The topics may broaden a bit, or sometimes be oddly specific.  Sometimes I may have to let go of a little bit of perfectionism if I actually want to get them out to post.  Doesn't matter.  Hello again and I hope you will join me as I try to communicate and work out for myself what it means to live life to His glory.

Happy Tuesday,

Shall we begin? Facts, theories, and laws (1)

Some time ago, I had a discussion with several friends regarding the meaning and use of the word “theory” in science.   By the end of this (2-part) blog post, it is my hope that readers will be able to identify the differences between “theories”, “facts”, "interpretations of facts", and “laws of physics”, and that they will be able to pick out key words that will help them to gauge the credibility and weight of a particular idea or concept in science.  
 
  • Facts are generally produced by measurement or observation.  These are things such as the sky being blue in the daytime in North America, or that it is easier to crush a clay pot than an iron one.  Generally speaking, the facts themselves are considered pretty objective, in that everyone can see the outcome when a test is performed or a measurement is conducted.  The caveat is that facts are usually interpreted within a specific framework.  We will return to this later.
  • Laws are statements that describe a phenomenon or event that occurs every time a measurement or observation is made.  Generally speaking, if you hold some object at shoulder height and then open your hand and let it go, it will fall towards the ground.   Laws don’t describe why the object falls toward the ground - just that it happens, over and over again.  The more carefully we study dropping objects, the more detailed the law can be - we may even be able to describe how quickly it will fall, how much time it will take to reach the ground, and whether or not it will speed up as it falls.  These details still don’t answer the question of why.  Laws are called such because they can be reliably reproduced under a given set of circumstances.  Now, if those circumstances change, eventually we can set up a situation in which these laws break down.
  • hypothesis is an untested idea or hunch about something that has been observed. Many times, these ideas arise from studying laws and making predictions about what would happen under various changes in the circumstances.  A good hypothesis will be testable and falsifiable - that is, you can set up some type of experiment or search that will test the hypothesis, and they hypothesis is set up in such a way that it can be proven wrong.  Often, hypotheses begin to try to answer some of the why questions surrounding laws and facts.  Successful hypotheses (confirmed by experiment) can help bolster confidence that your understanding of some of the why questions is on the right track, because you were able to successfully predict what should happen in a specific case.  It doesn’t necessarily prove, however, that every part of it is correct.
  •  A theory is a framework in which you try to make a consistent, coherent interpretation of facts and laws.  It can include or inform hypotheses, but theories are not the same as hypotheses.  Theory will make predictions that can be turned into hypotheses based on previous observations, facts, and laws.  If tests of those hypotheses turn out to be successful, the theory gains credibility.  Well-established theories have been tested over and over again, ideally by making predictions that have been shown to be correct.  This does not mean that the theory is completely true, or that it will never need to be modified as new information comes to light.  It can, however, show that the theory is a good framework from which a basic understanding of the underlying laws can be gained, and that it makes sense to consider the theory a reasonable interpretation of the facts.  
  • An interpretation of facts, in the way that I use it here, is the set of things that we assume the facts tell us, based on the coherent picture or framework or theory that we use to explain the facts.  In other words, once we have collected the facts and built a reasonable theory about why they should be so, we begin to look at new facts through the lens of what they would mean in our theory.  
Let’s give an example. Let us say that Jim had a birthday, and Sue baked a cake.  Polly baked a cake on Elliott’s birthday.  Cassidy baked a cake on Katrina’s birthday.  These are facts.  As a matter of fact :), by travelling from city to city, we find that in the United States of America, people often bake cakes and decorate their houses when the birthday of a family member or friend draws near.  The cake is often baked on the same day as the birthday.  This happens over and over again, and we’ve been able to document it.  This is the birthday law.  Note that we can all think of exceptions to this law, so it doesn’t hold under every circumstance - for example sickness, or conflict, or perhaps even personal beliefs or indifference.  Nonetheless, there is a large number of cases with general conditions in which we find this to be true.  So we call it the birthday law.  
Now WHY are cakes baked on birthdays?  This we do not know, and it is not included in the birthday law.  We might even be able to add more information to the birthday law, making predictions of, say, the ethnicities and ages of people who bake cakes on birthdays, or where they live. We could test these hypotheses and add the new information to our description of the birthday law.  But these things still doesn’t really tell us why cakes are baked on birthdays.  
 
We can start to collect all of these hypotheses together to form a theoretical framework.  In this example, we may not have all the answers to why cakes are baked on birthdays, but we can at least begin to assemble our various hypotheses and laws into a theory of birthday celebration.  And I can begin to use this theory to interpret various facts:  If I am in Thistown, USA, and Pedro bakes a cake with sprinkles and candles for his brother Peter, I might assume that today is Peter’s birthday.  Notice that the interpretation of the facts (that the baked cake means that it is Peter’s birthday) is not quite the same as the facts themselves (the actual baked cake), and can be wrong - Peter’s birthday might be tomorrow or might have been two weeks ago.  It also might not be his birthday at all, and they both just happen to appreciate the taste of sprinkles.  We were just interpreting the facts through the lens of our birthday theory.  
 
 
To be continued.  We’ll discuss the keywords next time, but below are a couple of articles that I found to be well-written and helpful in explaining the differences between laws, theories, interpretations, facts, and hypotheses.  I also welcome comments - did you find this helpful? Confusing? Useful? Let me know!

Computing Sidebar: TeX stuff

I recently upgraded my setup to Mac OS 10.11, which broke a few things, one of which was my TeX installation.  TeXshop is an open source distribution avaialble for Mac OS X that is installed with TeX Live when you download MacTex from the home page of the TeX Users Group (www.tug.org).  TeX is frequently used (including by me) for publications and dissertations (yay!)

Reinstalling MacTeX is relatively painless and well described by the instructions on the MacTeX download page (http://www.tug.org/mactex/mactex-download.html), so I will not repeat them here.  However, I did find that upon attempting to run the Tex Live Utility, I was unable to use the utility to update packages, and repeatedly encoutering the error “Listing Failed” under the update section

My problem was that the utility was unable to access the server for the repository that it was attempting to use for the software updates.  After searching blogs on some slightly different bugs and problems (e.g. http://mirror.ctan.org/systems/texlive/tlnet), I finally resolved the issue by switching to a new repository.  The steps: 

  1. Select the menu “Configure" —> “Manage repositories”
  2. Choose another repository by double-clicking or whatever you do for your computer to follow a link selection
This should ask you about using the new repository as your home repository as well (I accepted; probably not necessary), and give a confirmation dialog.  I was also prompted to accept an update of the infrastructure of the utility, which I also accepted.  
I recommend restarting the TeX Live Utility after the repository change, and particularly after the update to the infrastructure.
The infrastructure can also be updated by selecting “Reinstall TeX Live Manager” from the “Actions” menu.

Finally, after the repository change and upgrading the utility, I am able to use the utility to update my TeX packages by selecting “Update All Packages” from the “Actions” menu (updating selected packages is also possible).

This fix was performed for Tex Live Utility v1.23 on Mac OSX 10.11.2  (El Capitan).

 

Voila! Happy TeXing!

My Favorite Psalm

"The heavens declare the glory of God; and the firmament sheath his handiwork.
Day unto day uttereth speech, and night unto night sheweth knowledge. 
There is no speech nor language, where their voice is not heard.
Their line is gone out through all the earth, and their words to the end of the world.  In them hath he set a tabernacle for the sun, 
Which is as a bridegroom coming out of his chamber, and rejoiceth as a strong man to run a race.
His going forth is from the end of the heaven, and his circuit unto the ends of it: and there is nothing hid from the heat thereof.
The law of the Lord is perfect, converting the soul:  the testimony of the Lord is sure, making wise the simple.  
The statutes of the Lord are right, rejoicing the heart:  the commandment of the Lord is pure, enlightening the eyes. 
The fear of the Lord is clean, enduring for ever:  the judgements of the Lord are true and righteous altogether. 
More to be desired are they than gold, yea, than much fine gold:  sweeter also than honey and the honeycomb. 
Moreover by them is thy servant warned:  and in keeping of them there is great reward. 
Who can understand his errors? cleanse thou me from secret faults.  
Keep back thy servant also from presumptuous sins; let them not have dominion over me:  then shall I be upright, and I shall be innocent from the great transgression. 
Let the words of my mouth, and the meditation of my heart, be acceptable in thy sight, O Lord, my strength, and my redeemer."

Psalm 19

Life takes GUTs....

The intricacy and unity of the universe is one of the coolest and most amazing things to think about. It's funny how many things "matter but don't" (but do). The strong force keeps the very nuclei of atoms from ripping themselves apart, but acts over distances so short that it's undetectable on macroscopic scales. Gravity holds the galaxies in clusters, but is weak enough in everyday life to be bested, at least temporarily, by a little girl jumping or tossing her doll.
Life is the same. We eat, we sleep, we fight, we play. At the end of it all, the only thing that really matters is what we do with the priceless gift of salvation offered by God's Son, Jesus. But the little things on this side still matter. They can draw people to Jesus or help them find reasons to back away. They can show growth of character or the onset of compromise. The "equations" you live by can unify or unravel in an inconsistent mess...

Quantum Mechanics and the Gospel

In physics, as in mathematics, one often deals with *asymptotes*, defined by Google as "a line that continually approaches a given curve but does not meet it at any finite distance". This concept shows up pretty much everywhere. When you're talking about asymptotes, the bottom line is that basically, you follow this smooth line forever and ever, but it never quite gets you where you're trying to go, never quite reaches that point that it's trying to hit. You approach a value, getting closer and closer, but by less and less, and ultimately, you fail.

For weeks, maybe months, this is the picture that I've gotten in my head when I think of the concept of works righteousness versus grace. You can do all you can do to earn your salvation, but in the end, the Bible says that "all our righteousness is as filthy rags" (Isaiah 64:6) . You just won't get there. You just can't do it. There's a huge, unbridgeable gulf between what we can do and what God requires, and unlike in math, you never even get close enough to "assume" you're there and move on.

So what can you do? Nothing, if you just keep following that line. But, chips ahoy! There's hope! It's like ... A quantum leap!

Now we're looking at a little change of metaphors. In quantum mechanics, particles don't go smoothly from one state to another, because contrary to the assumptions of calculus, the energy states aren't continuous - there are only a few, particular, separate states in which it can exist, and it can only change states when the right amount (and nothing less) of energy has been absorbed or released by the system to permit it. Adding less than required and trying to give it a chance to "build up" won't work. (If you like science and aren't familiar with this, check out the photoelectric effect. Its discovery is actually the reason that A. Einstein won the Nobel Prize.) The set of possible energies is discrete. However, though there's a vast and gaping discontinuity between one state and the next, if there is something that can provide what's needed to make the change, it can be made.
And this is the hope that Jesus provides for us. We couldn't do it, but he met the standard and paid the price, fully. Nothing more was needed. The thing is done.

Hollapraize :)

Repost!

So, I really will update and finish this soon. There's been kind of a lot going on. In the meantime, I merged this with an older version of the blog, so if some of the dates are a little surprising, well, that's what happened. Look forward to posting more soon!

Free Particles

(Author’s Note:  In order to post entries in a timely manner, it has become clear that it will be necessary to break some entries into several  posts, even if some of the posts are quite short.  This is one of those entries…)

One of the interesting concepts of physics is that of a free particle. 

Often when the word “free” is used in the general vernacular, it invokes a sense of unlimited choice.  Be who you want to be, do what you want to do – no rules, no limitations.  The possibilities are endless.  There is no right or wrong.  This is not quite correct.

“Free” is a much richer concept than “having an endless supply of options”.

To be continued…

Preface: A Christian and a physicist

Psalm 19:1-3 states:  “The heavens declare the glory of God, and the firmament sheweth His handiwork.  Day unto day uttereth speech, and night unto night sheweth knowledge.  There is no speech nor language, where their voice is not heard.”

This is one of my favorite verses in the Bible.  The very creation that we observe each moment gloriously displays the majesty and beauty of our God.  As both a Christian and a physicist, I am fascinated whenever I notice a parallel between a natural law and biblical truth.

I would like to establish my position from the outset.   I am a Christian.  My worldview is that God created the heavens and the earth from nothing.  I believe that the Bible is literally true.  I believe that Jesus is the Son of God who came to Earth and died on the cross for my sin, rose again on the third day, and now sits at the right hand of God the Father, preparing a place for me.  I believe that I have been born again and filled with the Holy Spirit, that God is my Father, and that I will live for ever and rule and reign with Jesus the Anointed one in the ages to come.

I also believe that God has called me to be a physicist.  I believe that well- conducted observations and experiments on natural systems can lead to the discovery of useful and decipherable patterns, which in turn can be used to describe the universe in which we live and make reliable predictions regarding the evolution of those systems.  I believe that through repeated experimentation, accurate, reliable results can obtained and used to enhance our understanding of the world around us.  I believe that, properly understood, some of these results can reveal and illuminate the character of God.

I believe that the Bible is the final authority on any subject.  This means that where there is uncertainty or speculation, the Bible is the final, ultimate Word of God on the subject.  Future illumination may come.  When it does, to be sure it will uphold what has already been revealed in the recorded word of God.  I believe that the aid of the Holy Spirit is essential in the correct interpretation of the Bible, as is the careful application of hermeneutics and exegesis.  Christians call this “rightly dividing the word of God”, as in 2 Timothy 2:15. 

I believe that there are some subjects on which the Bible is largely silent, and others in which few details are provided.  In many of these cases, I believe that speculation can be sustained, as long as:
1.  The speculation doesn’t contradict known biblical truth.
2.  The truth of the Gospel is upheld.
3.  There is strong evidence in favor of the hypothesis.
4.  The understanding that the hypothesis or speculation is subject to change with additional revelation or new evidence is upheld.

I believe that true, objective science ultimately points to the conclusion that there is a Creator, that the Creator is the God of the Bible, and that His interactions with man have been real and historical. 

I do not want anything that I say or write in this blog to become a point of contention for members of the Church, or a stumbling block for those who are genuinely looking for a relationship with God and His people.  There have been instances in history where some aspect or theory of the contemporary science was connected with a particular interpretation of scripture, and the Church unfortunately fell into the trap of dogmatizing the associated interpretation.  Later, when the theory was superseded or discredited through new evidence, many saw it as a threat to or a proof against the scripture as well.  This led to all kinds of strife, antagonism, and animosity both within the church and between the church and the world that they were supposed to evangelize.  This is not my aim.  I simply want to share my excitement over what I believe are fascinating and telling parallels between the laws of physics as we know them and the laws of God as they have been revealed to us. 

I hope that you enjoy sharing my journey.

Scale Up



Picture: NASA Astronomy Picture of the Day, Oct. 14 2009: "The Pleiades and Stardust"
I've recently been humbled by the realization that were we not specifically created, our existence would be completely insignificant.
I was listening to an old Astro C10 podcast by my university (Woo!!) and the facts are astonishing.
Consider: On the size scale where the sun (which, mind you could fit about 1,000,000 earths for volume) is the size of the period at the end of your sentence, the nearest star would still be nine miles away. The galaxy contains billions of stars. Then when you imagine all of the star systems, galaxies, nebulae, and superclusters you start to see just how small we really are. One wonders that God can even see us, much less be involved or concerned with some moving dirt on a relatively microcopic speck of the universe. (And we're nowhere near being the smallest parts of the universe - there's atoms, and nuclei, quarks, gluons, leptons; maybe strings...so much detail!) Meanwhile, you can also make comparisons on a time scale - the universe is currently estimated to be around 14,000,000,000 (14 billion) years old. The average human life is about 70 years. The ratio there is 0.000000005. (Five nanoseconds, or five billionths of a second.) A human blink is on average about 300 milliseconds (.3 seconds), so, by analogy, if your life was 5 nanoseconds, then just in the time it takes to blink you could live about about 60 million lifetimes. Even if you don't believe that this is the correct age of the universe, you can see my point - everything that we do, every vacation you take, every career you pursue, every generation of a family that lives rises and falls in a ridiculously trivial amount of time. It reminds me of David's prayer - "What is man, that thou art mindful of him, or the Son of Man, that thou visitist him?"

Kind of makes eternity a little more impressive...
