No, my son, David, didn’t really balance those when he was three.

But he did google up vsauce videos. On his own. Why?

To find out why not all infinities were the same, of course!

For several days, he would watch and rewatch these videos stopping and backing them up a little to make sure he understood well what he saw.

So, it’s possible to do the impossible even faster than thought possible!

Did you ever need to solve an algebraically impossible formula?

Easy. Program a computer to guess for a few hours, and get a really inaccurate guess that may be close enough. That’s common, but there’s a better way!

Did you ever scream your lungs out in pain after mangling your work?

• Did you back up your manglings?
• Did you back up your manglings over your last good version of your program?
• Or did you role something into production and find the error later and need to know what change blew things up?

You’re not alone.

Version Control to the Rescue!

What are “Perceptrons”?

Around 1957, a Computer Scientist named Frank Rosenblatt at Cornell came up with a machine called, “The Perceptron”. It was an actual, physical machine. You can read more on this on Wikipedia.

This was initially a machine with actual physical motors and potentiometers (volume controls–variable resisters–things that usually have knobs for raising and lowering volumes on radios and amplifiers).
