oxygen magnesium 

Abbreviated form is OMg. Originally created to make fun of people who say OMG, so instead you would say "oxygen magnesium!!"

Unfortunately, it was later discovered that it would actually be magnesium oxide (MgO) but the joke still stands.

Some girl: Look at her shoes, aren't they ugly??
You (overhearing the above): Oxygen magnesium!! That's horrible!!

Chloro(2-thienylmethyl)magnesium 

Chloro(2-thienylmethyl)magnesium, or TP-MeMgCl, or 2-thiophenylmethylmagnesium chloride is made from 2-(chloromethyl)thiophene. It's a grignard reagent and an intermediate that can be reacted with acetonitrile to form TP2P (ThioPhenyl-2-Propanone). Then Molecular Formula
C5H5ClMgS
Average mass
156.916 Da
Monoisotopic mass
155.965088 Da

Tony: I synthesized Chloro(2-thienylmethyl)magnesium by reacting 2-(chloromethyl)thiophene with magnesium turnings in diethyl ether. I replaced the diethyl ether with dibutyl ether and reacted it with acetonitrile and hydrolyzed it with hydrochloric acid to yield TP2P (ThioPhenyl-2-Propanone)

Mr Mafnasium 

Mr Mafnasium is a religion we have made for a really sweet and swag teacher that we were blessed to have during our years in middle school.

Despite making us run a lot, he still had fun activities and plans for us to do during each lesson. (Personally my favorite was the volleyball unit in 7th grade.)

Some of his students slacked off when it came to distance learning, and some continued to be straight A’s. But in all he was a great and impactful teacher to us.

He prioritized our health, and encouraged us to be strong, to keep pushing through. On our last day of class with him, he melted the hearts of many while also relieved some’s (mine in particular) anxieties.

Me and several classmates have deemed him to be a precious existence and now we’re hesitant on moving onto high school. We hope to revisit him some time.

Wow you should join that religion called Mr Mafnasium!
