Guide to the ACME EDM Experiment: Why CP Violation Might Explain Everything About the Universe

Why should we care about the existence of the electron electric dipole moment (EDM)? In a previous post, we established that the existence of an electron EDM would imply a violation of a symmetry in physics called CP-symmetry, or CP violation (CPV). But it isn’t clear why CPV has any importance beyond being something interesting … Continue reading “Guide to the ACME EDM Experiment: Why CP Violation Might Explain Everything About the Universe”

Guide to the ACME EDM Experiment: Symmetries in Physics

In this series so far, we’ve discussed a lot about the physics of the ACME EDM experiment: the atomic physics methods we use to look for a small asymmetry in the electron’s charge distribution. However, we’ve never tackled the big question directly: why does the electron’s charge distribution matter at all? The precision achieved on the … Continue reading “Guide to the ACME EDM Experiment: Symmetries in Physics”

Guide to the ACME EDM Experiment: Differential Measurements to the Extreme

In our overview of the ACME experiment, we outlined the broad method of the experiment: we measure the deformation in the shape of the electron by performing spin precession on the molecule ThO. In the post about atomic structure, we outlined the basics of energy levels in a molecule, as well as that of ThO itself. … Continue reading “Guide to the ACME EDM Experiment: Differential Measurements to the Extreme”

Reading Walton’s Views on Genesis, Part 4: Reworking Inerrancy

The third and final book of John Walton’s Lost World trilogy, The Lost World of Scripture (LWS), expands its scope from reading the first few chapters of Genesis to the whole Bible. Written together with New Testament (NT) specialist D. Brett Sandy, the book sets forth a more enlightened understanding of what biblical inerrancy should mean. There are … Continue reading “Reading Walton’s Views on Genesis, Part 4: Reworking Inerrancy”

What Does Day-To-Day Work Have To Do With God?

(Originally written for YMI of Our Daily Bread Ministries. I have talked about the scientific aspects ACME experiment several times in this blog. This piece gives a few glimpses into the personal and especially spiritual side of the life of a graduate student on the experiment. It explains why I feel working on ACME to be … Continue reading “What Does Day-To-Day Work Have To Do With God?”

Guide to the ACME EDM Experiment: Atomic Structure

In the first two general articles I wrote about the ACME EDM experiment, I outlined the basic goal of the experiment (to measure the electron electric dipole moment) and the broad principle of how we accomplish that (by performing a spin precession measurement on a molecule in an electric field). Here, I will get into … Continue reading “Guide to the ACME EDM Experiment: Atomic Structure”

Guide to the ACME EDM Experiment: A Simple Overview

In the first introductory post of this series I outlined the immense precision of the ACME experiment in measuring the electron’s “shape.” A natural followup question is, how did we do that? In this post I will outline the basic measurement scheme in our experiment in the most general way possible, avoiding most of the technical … Continue reading “Guide to the ACME EDM Experiment: A Simple Overview”

Introducing the ACME EDM Experiment

It’s been almost two months since I last updated this blog, and the reason is because I’ve been utterly busy with both my courses and all the research going on in my experiment. As you may have read on my biography page, I am a physics Ph.D. student in the Gabrielse group at Harvard University, … Continue reading “Introducing the ACME EDM Experiment”

Gibbon, Part 15: The Fall of Constantinople and the End of the Roman Empire

We have finally arrived at the last stage of the history of the Roman Empire: the ultimate fall of the capital of the Byzantine empire, from which the Byzantine royalty was never to rise up again. It has taken me over two months (from June to now) to come to this point. Reading Gibbon is … Continue reading “Gibbon, Part 15: The Fall of Constantinople and the End of the Roman Empire”

Gibbon, Part 14: The Last Centuries of the Roman Empire

As we saw in the previous post, the events of the Fourth Crusade could have completely annihilated the Byzantine empire, if not for the efforts of Theodore Lascaris. Through the lucky bravery of this man, who was not even a member of the ruling Comneni by blood, the complete elimnation of the declining empire was delayed for another … Continue reading “Gibbon, Part 14: The Last Centuries of the Roman Empire”
