Here's a fun experiment! I have three colorless solutions. What color do you think they make when mixed together?

Chemistry is like magical art, but better because it's real!

Do not recreate this experiment at home. I'm working with hydrochloric acid, sodium hydroxide, and phenolphthalein. This color change is a result of a pH shift during an acid/base neutralization. Individually, these chemicals can be harmful.

I wired a circuit board with an RGB LED and wrote a program to make it do this for an assignment in electromechanical systems.

This was fun! Do you have fun with any of your assignments?

If there’s interest, I’ll go over the code but I’m far from an Arduino expert. I just started using it this semester.

Arduino light show I wrote a code and wired an RGB LED to do this for a class assignment in Electromechanical Systems.

Both can be fun!

This is the first OU merch I've ever felt inclined to purchase. I'm super proud to be a chemical engineering student! 💕🤓

Today is Carl Friedrich Gauss's 244th birthday. He revolutionized nearly every area of mathematics and made breakthrough contributions to our understanding of electricity and magnetism. He calculated the orbits of Ceres and Pallas. He was an inventor and created devices to measure electricity, magnetism, and the shape of the earth (heliotrope). Could you imagine doing all of this before there were computers? Happy birthday Gauss!

Little Earth looks happy with her moon! Thanks Jupiter!

Are you curious about particle physics, the Large Hadron Collider, CERN, and Higgs Boson particles? Check out this Zoom discussion from one of the CERN physicists who helped prove the existence of Higgs Boson particles! This was a very interesting discussion!

This is a story about a couple kids with dwarfism. They are among the few receiving a new therapy to help prevent some of the issues they would otherwise face with their condition. This is very fascinating!

Revolutionary treatment helps dwarfs grow | 60 Minutes Australia The beautiful little kids in this story are just like yours and mine, but for one faulty gene. They’re the one in 20,000, for who statistics on dwarfism beco...
