Cosmic Discord

Dealing with astronomy data means I often need to deal with information collecting. Most of the time the API from the websites is powerful enough, I don’t need to make any extra effort to clean the data. Once in a while, I am not happy with learning all the grammar... [Read More]

Now let’s continue to understand the recent g-2 result. Last time we briefly touched upon how current loops respond to an external magnetic field, and why electrons and muons fall into this category due to their spin. Now let us sketch how the value is actually related to the spin.... [Read More]

A few of my friends asked me about the recent Fermilab results. We know that recently there is some “anomaly” going on at Fermilab, and the result is statistically significant when combined with the previous measurement from Brookhaven National Laboratory (BNL). This post will be mostly for the background. I... [Read More]

Last time we talked about two types of cosmic distance. Since I am a beyond the Standard Model (BSM) junkie – so are lots of my collaborators – the next question is naturally whether New Physics could affect this type of measurements. If yes, how much can the imprint guide... [Read More]

Some fun facts: the Sun is one astronomical unit away, which is \(1.5\times 10^8\) kilometers away from us – that is seven zeros after 15 – or 8 minutes 19 seconds away if you travel with the speed of light; the center of the Milky Way is about 8 kpc... [Read More]
