March Microscope Madness! (Week 5 - 2015)
Announcer: Frostbite Theater presents... Cold Cuts! No baloney!
Joanna and Steve: Just science!
Joanna: Hi! I'm Joanna!
Steve: And I'm Steve!
Joanna: And this is week five of March Microscope Madness!
We're about to reveal the answers from last week's video, so if you haven't watched it, you might want to go back and watch it now.
Steve: If you're ready...
Image one, which might have been a little bit unfair, because I'm not sure how many of you have seen one of these before. But, this is a casette tape and it's what we used to record our music on.
Joanna: Image two. Also, maybe a little unfair, a floppy disk. And, it's so old, even our computers can't read it.
Steve: And, image three. A CD, where you can actually see the data that's written to the disk.
Joanna: Alright! If you're ready for your last three images, here they are!
Image one, taken at a magnification of one hundred.
Steve: Image two, taken at a magnification of thirty five.
Joanna: Image three, taken at a magnification of two hundred and fifty.
Okay! Give us your suggestions for next year and stick around after the fog for the answers to this week's images!
Joanna: Welcome back! Here are the answers to this week's images.
Steve: Image one is the tip of a ball point pen.
Joanna: Image two, the camera lens on an iPhone.
Steve: Image three was really unfair of us. It's a prototype silicon-based photomultiplier. And 3,840 devices like this are installed in our newest experimental hall, Hall D, where they replace devices like this, which are classical photomultiplier tubes. And, maybe in a later video, we'll be able to show you around Hall D for real.
Joanna: I hope you've enjoyed March Microscope Madness! Thanks for watching and join us again soon for another experiment!
