Post questions you like to ask below
AMA took place in informal format. Post questions below to get ideas on what topics others are most interested in. For ideas on how this works, see previous examples in yuggib's, Slereah's and DanielSank's AMA
UNSW Bachelor of science physics and chemistry double major (2012-2016)
Chemistry (physical chemistry: Atmospheric chemistry and molecular dynamics) honours with topic: Investigation of the hydrogen production of acetaldehyde (2016). Link to research group page
I LOVE QUANTUM MECHANICS and I will DIE FOR IT!!
My expertise is mainly in chemistry and the major topic of the AMA is likely me talking about my honours project (the only thing I have technical info on that is not too far gone in my memory)
Therefore, asking me anything technical in physics and there will be a almost certain chance I made wrong statements. However I can talk to you about roughly what I learn when I browse relevant physics topics in the past in popsci, journal articles and also in my uni studies.
Please refer to "short version" for my interest highlighting only the strongest interested topics in each field
Science interest (SHORT VERSION)
- Quantum mechanics (QM): ALL!
- Quantum field theory (QFT): Nonperturbative methods and interacting fields in curved spacetime, mathematical foundation that does not start with classical fields nor particle notations.

- Any math object that has something to do with the prefix non- and/or the concept empty. For example
- Symmetry and asymmetry and their properties

Chemistry interests and research experience
Physical chemistry: some experience with Quantum chemistry theoretical frameworks (MP2, CCSD), some experience with transition state models, some experience on calculations with Gaussian 09, some experience on working with lasers in molecular beam ion imaging, some experience with simple atmospheric chemistry and physics models. Wish to learn a lot more about the quantum mechanics of non born oppenhenier systems and state transitions in a chemical reaction. Geometry of the potential energy surface of a system. Unusual molecular dynamics such as roaming and non transition state dynamics. Organic and metal chemistry mechanisms.
Organometallics: Some knowledge on the basic chemistry of organoruthenium and organoiron. Knowledge on air sensitive techniques. Knowledge on interpreting multinuclear NMR spectroscopy.
Interests in: Metal complexes and other coordination compounds, main group chemistry, other organometallics, energy storage systems involving non hydrogen fuel cells and thermoelectrics, organic chemistry that does not involve drugs (unless the emphasis is the mechanism of the drug or drug delivery system (I fed up with too many people simply make a new drug without study much about how it works)), role of small molecules and other hormones in regulating activity of microbes and ecosystems. Radiochemistry for product manufacture roles, superheavy chemical elements and their properties. Theoretical chemistry (various types of models on how chemicals react and bond, their interactions with physical entities such as magnetic fields etc. at the wavefunction level). Green chemistry (environmentally friendly and efficient ways in doing experiments) and much more
Science fiction related interest and personal projects
- Worldbuilding (approaches, how to ensure consistencies etc.)
- Time travel model that is physically plausible (or at least consistent) to unify all known time travel plots and thus provide a quantitative way to calculate when things happen, thus make time travel stories less confusing and to address the poorly considered problem of what is seen for the natives and the issue of multiple time travelers (current attempt here)
Physics of scifi that can be realised in the near future (Check Physics of the Impossible for examples on what I mean)
Idea mixing: Massive abusing of analogies and properties of mathematical objects in a less rigorous fashion to make jokes or connecting dots between two dissimilar ideas. Mixing of ideas from other field of study and see what comes out.
- "Question theory": How to ask/generate sharp and precise questions that optimise potential insights or leave no loopholes
- Circumvention: How to abuse legal and semimoral loopholes, and how to detect and close them
- Color tiles: Categorise color palettes commonly used in various media and their symbolism
- Laymanisation: Explaining highly techinical terms in easily understood fashion to a layman without compromising too much rigor and details. Visualisation play an important role on this
- Irreversibility: How to make a move or process more effective by cutting off as many alternate pathways it can evolve into something else otherwise. How to generate maximal hopelessness to a target. How to interrogate for information without actually using interrogation tehniques
- Collector of exotic substance: E.g. Trying to work out how to experimentally stablise particles, chemical species so I can bag them and store them at home. Side effect might be I am particularly good at sourcing and storing all sort of materials that otherwise require careful treatment.
- Music. Played the piano about 10 years ago. Otherwise occassional electronic music fragment composition with music production software like FL Studio and MuLab. An interesting accidental example here.
- Art: I like some impressionist and surreal art, some installation and digital art, non picasso abstract art (picasso's is too blocky and too low resolution thus confuse me everytime I tried to look for the subject of the works), artwork and forms involving geometric shapes, curves and scenery. How to interpret art. Its relation with science, religion and magic. I have little preference for art where people are the subject. (Having said that, my art interest only exploded on 2015, thus please do not ask me technical question about art because I am not an expert)
- Magic and esoterics: What makes magic magic, what exactly is the key thing of esoterics, The relation of it with science and religion and other thoughts. Various ways to do magic documented in history. Psychological underpinnings of apparent sighting of miracles. See if there are ways in magic thinking that are actually transferable knowledge that can be used to benefit scientific discovery (I am obviously not an expert since this interest starts also on 2015)
- Various types of computer games, focusing on the story, the game elements, level design and aesthetics. I also enjoy game art. (Again I am not an expert thus avoid asking technical questions on that)
- Acting like scifi labs announcement systems: You will see a lot of signs of this in my chat activity, the way I talk and how the example of my work tend to be followed with a science log sounding description.
Science interest (Please note I can only be claimed an expert in chemistry fields because I made too many errors due to lack of physical intuition and incoherent thinking)

I am weird, VERY WEIRD. You either understand me, or you don't. But I like people who don't understand me, because they are much better at finding out how exactly I think and why I am weird (or not). They are also not easily think what I said implies it is creditable. This "unintentional echo chamber effect" is now identified as a major hurdle to understand myself and me learning knowledge in general. So, in a sense, people who don't understand me actually understood me better than myself and those who understand me.
Most of my interested topics are highly correlated to my personality traits
