Gentlemen, Know Your Nipple Shields

This is a nipple shield, and you just might need a few.

As you’re expecting your first baby, you may think the feeding of said newborn is something you, as a dad, don’t have to worry about; perhaps the only thing you don’t have to worry about.  Well, I'm sorry, but... well... you do.

As you may have heard, breastfeeding is a beautiful thing that strengthens the bond between mother and child; nourishes the kid like no other kind of food can; and helps to build their nascent immune system.  All of these thing are true.

What you may not know however, is that the mother of your child has heard all of the above, over and over since way before she became pregnant.  She’s heard it on the evening news, the morning talk shows, twitter, just about everywhere.  And in the months running up to the blessed day of deliverance, excuse me, delivery she’ll hear it even more.  Doctor’s offices, midwive's offices, and every pregnancy book, and web site available are slathered with ever more positive breastfeeding missives.

Here’s the thing though.  Even though La Leche, your doctor, your midwife, your mother-in-law, and heck even your own mom are loath to admit it: sometimes breastfeeding just doesn’t work at first.  The good news is that it will work eventually.  The bad news is that given the huge burden of the aforementioned breastfeeding expectations, when it doesn’t work?  It's a bit of a let-down. (That's a totally intended breastfeeding pun.  You'll find out.)  Expect sobbing and lots of it.  Labor, as well as your newborn's pheromones, (Number 3 caused some people to literally sob just by being handed to them), generates an overflow of hormones in everyone in the room.  Hormonal overflow + Unexpected La Leche Induced Stress = Sobbing.

When and if this happens, the first thing you’ll need to have is a handful of nipple shields.
Pro-Tip: Buy them ahead of time.
While virtually none of the breastfeeding material will mention nipple shields, they'r the first thing your midwife/nurse/doctor will suggest when breastfeeding doesn't go as expected.  However, when I made the emergency run to Target to pick up a pair after the birth of our first kid, they were almost sold out!

The second thing you'll need is a box of Similac.  I was raised on the stuff; my  mother could't breastfeed because of complications during pregnancy.  Even so, before we had our first kid, Similac was nothing to me but an entertaining anachronistic reference in a Bob Schneider song[1].  Nevertheless, you might need some to tide Junior over until all systems are go.  As you're madly scrambling through the store, you'll be looking for a logo like this:


The last thing you'll need is an appointment with a lactation coach.  That's right, there are coaches for breastfeeding.  Who would have thought?  It'll cost about $85, and they may or may not tell Mom, anything of any real value.  Our lactation coach was apparently educated at Hogwart's in Slytherin House.  She explained that you make a distinctive noise, (that sounded for all the world like a hiss), and then slap the baby's mouth onto the at-ready nipple.  However, when I summarized her method as "OK, got it.  Hiss, and slam the kids face onto the breast," our coach was more than a little aghast.  So, as I say, the value of the advice is debatable.  But, you know what?  That's not for us dads to judge.  Because what makes the $85 more than worth it is that the beloved mother of your child is going to exit the appointment with a newfound sense of stability and confidence, and life will go back to the normal, even simple routine of constant low-level stress induced by sleep deprivation shared by all new parents.

Cool Math Tricks: Deriving the Divergence, (Del or Nabla) into New (Cylindrical) Coordinate Systems

The following is a pretty lengthy procedure, but converting the divergence, (nabla, del) operator between coordinate systems comes up pretty often. While there are tables for converting between common coordinate systems, there seem to be fewer explanations of the procedure for deriving the conversion, so here goes!

What do we actually want?

To convert the Cartesian nabla



to the nabla for another coordinate system, say… cylindrical coordinates.



What we’ll need:

1. The Cartesian Nabla:



2. A set of equations relating the Cartesian coordinates to cylindrical coordinates:



3. A set of equations relating the Cartesian basis vectors to the basis vectors of the new coordinate system:



How to do it:

Use the chain rule for differentiation to convert the derivatives with respect to the Cartesian variables to derivatives with respect to the cylindrical variables.

The chain rule can be used to convert a differential operator in terms of one variable into a series of differential operators in terms of othe…

Lost Phone

We were incredibly lucky to have both been in university settings when our kids were born.  When No. 1 arrived, we were both still grad students.  Not long after No. 2 arrived, (about 10 days to be exact), mom-person defended her dissertation and gained the appellation prependage Dr. 

While there are lots of perks attendant to grad school, not the least of them phenomenal health insurance, that’s not the one that’s come to mind for me just now.  The one I’m most grateful for at the moment with respect to our kids was the opportunities for sheer independence.  Most days, we’d meet for lunch on the quad of whatever university we were hanging out at at the time, (physics research requires a bit of travel), to eat lunch.  During those lunches, the kids could crawl, toddle, or jog off into the distance.  There were no roads, and therefore no cars.  And, I realize now with a certain wistful bliss I had no knowledge of at the time, there were also very few people at hand that new what a baby…

Lab Book 2014_07_10 More NaI Characterization

Summary: Much more plunking around with the NaI detector and sources today.  A Pb shield was built to eliminate cosmic ray muons as well as potassium 40 radiation from the concreted building.  The spectra are much cleaner, but still don't have the count rates or distinctive peaks that are expected.
New to the experiment?  Scroll to the bottom to see background and get caught up.
Lab Book Threshold for the QVT is currently set at -1.49 volts.  Remember to divide this by 100 to get the actual threshold voltage. A new spectrum recording the lines of all three sources, Cs 137, Co 60, and Sr 90, was started at approximately 10:55. Took data for about an hour.
Started the Cs 137 only spectrum at about 11:55 AM

Here’s the no-source background from yesterday
In comparison, here’s the 3 source spectrum from this morning.

The three source spectrum shows peak structure not exhibited by the background alone. I forgot to take scope pictures of the Cs137 run. I do however, have the printout, and…
