Hi! I'm new to your blog - just wondering what you're studying. Nice to meet you!

Hello Anon, I’m glad you have decided to follow my blog! I have actually switched majors many times, but my main area of study is biology, and that’s what I’m going back to school for.

Thank you so much! I'm starting dual enrollment at a local college and it's going to make me so happy to have an awesome looking calculator for my first college math class—all thanks to you! ^_^

Congratulations on the dual enrollment! I hope that you have a great time in your first college math class. It required a little more studying than high school, but I know I loved my first one. One thing is for certain: You are going to have the coolest calculator in class! I’m glad I could help.

Given the amount of asks I received last night about it, I’ve concluded that I should’ve worded the calculator post differently.  I also had no idea it would get so much attention!  

I did not make the faceplate or cover, I just bought them online.  They are made by Guerrilla Calculator Accessories.  You can find covers and faceplates by Guerrilla on eBay and Amazon. 

The cover itself is actually purple and has a decal bonded to it that gives it the star design.  It’s even better looking in person!  Since the edges of the decal seem like they can get worn, I’m going to put superglue or resin around the edges to make sure it doesn’t chip off.

What molecules are on your socks? (They look really cool btw)

To be honest, I’m not sure. I’m not the greatest at chemistry, and I don’t recognize them. I’ll try to find someone who could tell me, as I’m curious about it, too.

I absolutely admire your socks, where did you get them?

Sorry for the late reply: I actually got the molecule pattern socks from Walmart.

Since I’m going back to school soon, I gave my TI-84 Plus SE a makeover.  :)

Today, I saw this beautiful mockingbird on my way into work. She was protecting her fledglings and flew right up to me. I’ve definitely been close to mockingbirds before, but never this close.

To those who celebrate it, Happy Independence Day! Enjoy the parabolic envelopes that form while those bright, sparkling, parabolic curves are etched into the sky tonight…

What makes fireworks colorful?

It all thanks to the luminescence of metals. When certain metals are heated (over a flame or in a hot explosion) their electrons jump up to a higher energy state. When those electrons fall back down, they emit specific frequencies of light - and each chemical has a unique emission spectrum.

You can see that the most prominent bands in the spectra above match the firework colors. The colors often burn brighter with the addition of an electron donor like Chlorine (Cl). 

But the metals alone wouldn’t look like much. They need to be excited. Black powder (mostly nitrates like KNO3) provides oxygen for the rapid reduction of charcoal (C) to create a lot hot expanding gas - the BOOM. That, in turn, provides the energy for luminescence - the AWWWW.

Aluminium has a special role — it emits a bright white light … and makes sparks!
