Hello, everyone. My name is Professor Barnes. The class I'll be teaching this semester is introduction to lasers.

The word laser stands for Light Amplification by Stimulated Emission of Radiation.

Where are the lasers? This graphic here represents the electromagnetic spectrum arranged.

Excuse me, Professor?

Hi there, Andy Dwyer.

Curious, when will you be bringing out the lasers for me to play with?

And will we start with the small lasers or could we go just straight to the big lasers in terms of playing with them?

We won't be using actual lasers in this course. It's about the theory that makes them possible.

One of the most significant bummers of my lifetime.

T-B-T-L!

Hey there and welcome to a Friday afternoon edition of T-B-T-L.

This is the show. It's probably too beautiful to live.

My name is Luke Burbank. I'm your host at Step So 955 in a collector's series.

joined as always by Jen Flash Andrews, the long-time producer of the program. Hello, Jennifer.

Hello.

How's it going on this Friday? Are you T-G-I-F and or what?

You know it.

Oh yeah, good times. Good times. Do you have any big plans this weekend?

I'm going out to that Motifundation Benefit on Saturday night.

Oh right.

And I'm going to Woot Woot for Chris Pratt. I have a huge crush on.

You know, I'm always trying to play those parks and rec stuff on the show.
