Fission

                That's odd.. looking at a skin sample it seems like all of his cells are made of ionized atoms... That could help explain his ability to warp reality. He probably manipulates the atoms around him by adjusting the electromagnetic field made by his molecular- My thoughts where cut short by a cackling laugh from the being that happened to be a test subject, spirit of chaos, and source of many headaches.

                  "What is so amusing to you this time?" I asked in a rather irritated tone, lifting my eyes up from my microscope to look at Discord. He may be reformed but let's face it, sometimes he's still just a jackass.

                   "Oh! Anger, anger! Why are you so irritated? Still trying to make sense of chaos?" Discord taunted in that silly tone of his. I sighed and thought of the irony of the situation, Discord and science did not seem to mix, not even at the visual level, his brightly colored body looked very exotic in the pewter grey lab that also happened to be my basement.

                     "Everything has an explanation, even you." I told him as l looked back into my microscope. I heard a strange popping sound and looked up from my microscope again to see discord was now wearing a pair of glasses and a lab coat. Note to self: his creation of objects seems to  create noise and light, possibly an extroversive reaction?

                     "I believe in chaos theory personally." Discord said in a mock scientific tone. I mentally sighed at the mention of chaos theory, well he's not going to shut up until I snap anyways.

                      "Chaos Theory is a myth, if everything was doomed to chaos then you would still be wreaking havoc wouldn't you?" I explain.

                     "Atomic Flash! I'm shocked! You wound me!"  As Discord started to cry fake tears I noticed that the glasses and lab coat was gone. Note to self: either the destruction/reversal of his made objects is an introversive reaction..... or he makes the flash and sound as part of his theatrics. Wouldn't surprise me either.

                     "We are done for today." I inform the still weeping Discord, and he leaves without complaint. In reality Celestia had given me 45 minutes with Discord not 22, but you try to stay in a room alone with the spirit of chaos for 45 minutes and keep your sanity.  My computer started beeping.

                    "Unusual Sub Atomic Activity!"  It reported. I use my magic to manipulate the mouse as I put up my skin sample from discord, no telling when I'm going to get another sample of that!, and take a look at the atomic levels, average protons, neutrons, slightly above average electrons, Note to self: Possibly caused by discord's activity in the room?, trace amounts of potons, electronos,and  nuetatrons, Note to self: Evidence of an extroversive reaction! Evidence I tell you!, an average amount of photons, the sub atomic particle that was in extremely unusual amounts was aurons, an extremely rare particle that  I helped discover, it is created when magic is used and travels approximately 76 hours back in time from when it was created, Princess Celestia had asked me to pay careful attention to this molecule because of its congruency with certain events in equestria. The first time it had went off was about 3 days before the return of Nightmare Moon and the elements of harmony, then there was the time about discord coming back, twilight going back in time, the wedding incident, the ascension of Twilight Sparkle, and the everfree incident. After I reported the particle's ties to the events to Celestia after the wedding incident,  Celestia asked me to report to her if it happened again. I sighed and traded my lab coat for my blue and grey barding, which turned my coat grey, my tail and mane white, and my eyes to a dark yellow.As a junior member of the night guard, I will inform Luna instead for a change.
