Comprehending Science & Technology, 1st Period - Monday
"Now that we're all safe from the seventies, it's time to get back into technology. That's not an 8 track." Tony had to shudder at the thought. "Today is going to be about touch screens and how they work. You can the out your phones if you want."
Only class where you'd hear that. Right here.
"There are multiple technologies that can make a touch screen display, but at the moment two are the most commonly implemented on the market. The first is called resistive touch."
He fiddled with his phone for a second before a holographic image to show what he was referring to.
"Generally, the bottom layer will be glass, the top will be thin, pliable plastic, with a fine wire grid between them. Sometimes there's a gel in the middle layer as well, depending on the application. The premise of this system is that when you push on the screen it contacts the grid, which correlates to that particular area in the system. It's not terrible, but excessive use tends to break down the physical parts of the system. Very annoying."
So dismissive, Tony.
"The second system is what's used on your phones, it's called projected capacitance. The idea behind this is to remove the components that wear down over time with use, placing the conductors--the wire grid from before--under the glass layer. A very thin layer of glass that allows the natural electrical charge the human body generates activate the conductors. Try using your phones with normal gloves on. It doesn't work because the fabric prevents the small charges from getting through. Don't worry, they make special gloves for getting around that. It's just a thin metal string in the fingers of the gloves that allows conduction. I had touch free displays all set up for phones, but apparently they were cost prohibitive."
Tony shrugged. "Business. Okay, homework. Homework, homework, homework. Um. How about you kids compare your phones to what we found on the cruise. If you didn't go... play Angry Birds instead."
It was a hardship, right?

Listen to the Lecture

Also it was fascinating. Because she was a nerd.

Was that why the ship had been so chilly?
She was going to have to find this Angry Birds game.
Talk to the Teacher/TA
Plus side, they looked really cool for the Avengers.
Re: Talk to the Teacher/TA
But it was pretty awesome treason.
OOC
Lego games have warped my expectations.
