best expressed in words;
it's expressed in the
choices one makes

AFTER SPRING BREAK + THE PLAYLIST + PHYSICS DOWN THE DRAIN



After Spring Break

After Spring Break, I'll be sending you new material on Work and Conservation of Energy. Don't worry - Mr. Bugenhagen, Mr. Damm, Mr. Restad and I are very much aware that we're only supposed to give you about 20 min of work per day. We've done our best to make sure not overburden you, but if you feel that the work takes you longer than it should please let me know.

As far as grading is concerned, my plan is to send you problems; you do them on paper, take a pic and send me the pic. The paper should have your name on it and be in your handwriting. I don't think I'm going to do any quizzes or assessments at least for the next two school weeks, so your grade will be based on the work you send me.

Everything will be linked here in the Corona Diary, as well as on the regular CP and Honors pages at mrmont.com.



The Playlist

So here we are with 300 songs left in the playlist and no way to play them for you.

Or is there a way??

I've never used Spotify, for reasons that maybe I'll talk about another time. But now I have a reason to use it. I'll be creating weekly playlists based on the big playlist. I'll link them here, and at the regular CP and Honors pages on mrmont.com.

Corona Week 1 Playlist

Enjoy!

Apostrophe Frank Zappa 1973 Frank is one of my heroes.
Midnight, Monday and a Telescope Cotton Jones Basket Ride 2008
Xamenh Evtexia/Fiz'n 3 Mustaphas 3 1987 Love those Balkan rhythms, then things get weird.
Wake Up Run DMC 1984 Everything was perfect, but it was a dream!
Happy Jack The Who 1966
Jeremy Pearl Jam 1991
Limelight Rush 1981
Wonder Natalie Merchant 1995
Up from the South The Budos Band 2008
Gypsy Fleetwood Mac 1982
Remember Air 1998 Ms Newhart got this album for me many years ago. She doesn't often take a chance like that, but this is a great album.
Shout Tears for Fears 1985 Great song with an excellent but simple guitar solo at 4:35. It's not a virtuoso guitar performance, but it's right for the song. Never think that things have to be super-amazing to be really good.
My Bologna "Weird Al" Yankovic 1993 Remake of his first hit. Did you know that his main instrument was the accordion?
Fade into You Mazzy Star 1993
Victoria The Kinks 1969 There's a whole AP Euro lesson in here.
Name Goo Goo Dolls 1995 My interpretation (which could be completely wrong) is that famous people sometimes change their names. Knowing their real name is knowing a secret about them or their past - knowing who they really are.
Pump Up the Jam Technotronic featuring Felly 1989
Why Can't We Be Friends War1975 From the guys who brought you Low Rider.
Mony Mony Tommy James and the Shondells 1968
The World At Large Modest Mouse 2004



Physics Down the Drain

So I heard that water goes down the drain clockwise in the northern hemisphere and counterclockwise in the southern hemisphere. Or is it the other way around?

No matter, because it's wrong. We talked about how spin direction is conserved if there's not outside torque, and how when mass pulls inward, angular velocity increases.

What are the chances that the random motion of all the H2O molecules clockwise versus counterclockwise in a sink or tub exactly cancel out? Never happens! So whatever the net rotation of the water is takes over and becomes faster as the water's mass goes inward toward the drain.

Try this experiment. Put some water in a sink. Give the water a very gentle swirl clockwise. Then let the water out of the sink. Notice that the water close to the drain is spinning quickly the same way you swirled it. Repeat with a gentle counter-clockwise swirl and see if it still works.

Now don't go sticking your hand in the toilet to give it a gentle swirl and repeat the experiment because it won't work.

The openings that let water into the bowl point in a direction already to make sure the water spins. Engineers figured out a long time ago that spinning water helps the poopy go down better.

Yes, I said poopy. Did you smile? And why are bodily functions funny, anyway??

Enjoy your "break"!
