The compact disc player turns 35 this year. Sony's first CD player was released on October 1, 1982. At the time of its release, the CD was an enormous step forward in home recording technology—and nerds were excited.

In late 1982, an Australian TV show called Towards 2000 dedicated a lengthy segment to the arrival of the CD, "the ultimate in recorded sound." In the segment, presenters ran through various significant sound-recording milestones, showing off all sorts of needles, horns, hand-cranks, and so on. The "microgroove" LP was effectively the height of recording technology until 1982.

Nearly three minutes into the TV segment below, we see our first compact disc. Mind blowing! The presenters explain that there is no needle involved—it's frickin' lasers.

We get a tour of CD technology, including early players with big clicky buttons. My favorite part of this trip down memory lane comes near the end of the segment, when presenters suggest that one day, CD players might even find their way into cars!

Tune in, and be reminded what mind-blowing tech looked like 35 years ago:

What Is the Electoral College?

The Electoral College is a process used in the United States to elect our president. It was established in Article II of the U.S. Constitution.

It was created to address a series of technical and political problems that were present in the early days of our democracy—most notably, the issues of slow communications (it took tremendous time and effort to get vote tallies back to Washington from distant states) and of suffrage (the idea of a pure popular vote was a hard sell when you had Southern states containing large populations of enslaved African Americans and unenfranchised women). But we've been doing this national election thing for a couple hundred years, the suffrage issue is sorted out, and we have good telecommunications—so why do we still have the Electoral College? In a word: Federalism. In a few more words: The framers of our Constitution deliberately set up an indirect democracy.

There are lots of interesting arguments for and against the system. In the below video, YouTube educator C.G.P. Grey explains the issues inherent in the Electoral College. Take a look, and consider the question: Is this system really fair?
