A Sad Update And One Sweet Diversion

Once again, into the darkness

So, here we are again.

In Nashville two days ago, the U.S. suffered its 131st Mass Shooting of 2023. That’s 131 in 86 days, for a rate of 1.52 a day — thus far.

This was also another Mass Murder, the 13th of the year. What’s the difference?

The Gun Violence Archive, which began documenting gun violence in the U.S. in 2013, defines a mass shooting as a gun violence incident in which four or more people are killed or injured, excluding the suspect or perpetrator.¹

The FBI does not have a definition for mass shootings; rather, it tracks mass murders, which it defines as an incident in which four or more people are killed.  It includes gun violence, bombings or any other incident where four or more are killed. Mass Murder would statistically be a subset of Mass Shooting.

Consequently, in the first 86 days of 2023, there have been 131 mass shootings and 13 mass murders. The event in Nashville added to both categories.

Regardless of definitions, what really matters is that in the first 86 days of 2023, 10,009 people who were alive to welcome in 2023 on New Year’s Eve are now dead by gun violence, 4,267 by homicide; 5,742 by suicide.

Gun violence incidents rocketed to another level in America in 2020 as the Coronavirus gripped the country, and since then they have not slackened at all.

I have periodically been writing about gun violence since 2005, and most recently just two months ago in January of this year.

I’m not going to rehash what I’ve written previously. I urge you to read the column from this past January. It says it all — except for one thing. It doesn’t discuss the children. In yesterday’s obscene brutality, the obviously deranged shooter killed three nine-year-old children. They were Evelyn Dieckhaus, William Kinney, and Hallie Scruggs. Also killed were Mike Hill, 61, Katherine Koonce, 60, and Cynthia Peak, 61.

This is how bad things have become: guns kill more children than any other cause.

As I reported in May of 2022, the US dwarfs the 28 most economically developed countries in the 38-member OECD in deaths by firearms. Not only is our firearm death rate nearly 25 times higher than our OECD companions, our total homicide rate is eight times higher. In America, 98 people die by firearms every single day. In those other 28 OECD countries, with a combined population more than twice that of ours (712 million vs. 331 million), that number is 19.

I have found people to be mostly the same the world over. Many are smart; some are not. Many are wealthy; most are not. But we in America have two things other countries do not have: more guns than people and sky-high homicide rates.  The first leads to the second. Why? Because guns can kill fast and from a distance. It’s hard to outrun a bullet. Other methods often take some time during which a victim has a chance to run away. Countries with far fewer guns have far fewer homicides. Simple as that.

Rather than doing something about the root problem — 393.3 million guns — we’ll continue to nibble around the edges mistaking movement for progress. And more nine-year-old children will die.

What kind of allegedly enlightened society allows this to happen?

Only ours.

And now for a sweet diversion

Do you know what rheology is?

To save you the trouble of looking up the answer, I’ll tell you.

Rheology is the branch of physics that deals with the deformation and flow of matter, especially the non-Newtonian flow of liquids and the plastic flow of solids.

There. Now you know.

This is a story of rheology, an Oreo cookie, and how a couple of MIT kids may have too much time on their hands.

Graduate student Crystal Owens and undergraduate Max Fan set out to solve a cookie conundrum that I’m sure has baffled you forever: whether there is a way to twist apart an Oreo and have the filling stick to both wafers. For Owens, the research “was a fun, easy way to make my regular physics and engineering work more accessible to the general public.”

According to Fan, “There’s a fascinating problem of trying to get the cream to distribute evenly between the two wafers, which turns out to be really hard.”

In fact, they couldn’t do it. PhD candidate Owens, who studies the properties of complex fluids, said, “Videos of the manufacturing process show that they put the first wafer down, then dispense a ball of cream onto that wafer before putting the second wafer on top. Apparently that little time delay may make the cream stick better to the first wafer.”

In the lab, the research team subjected Oreo cookies to standard rheology tests (whatever they are) and found that no matter the flavor or amount of stuffing, the cream at the center of an Oreo almost always sticks to one wafer when twisted open. I have no idea how many of the failures were eventually consumed, but I think it would have been a shame to waste any of them. Maybe they had after work Oreo and Gator Aid² parties.

And to show you how MIT students go to lengths you’ve probably never dreamed of to solve a problem, Owens and Fan designed a 3D-printable “Oreometer” — a simple device that firmly grasps an Oreo cookie and uses pennies and rubber bands to control the twisting force that progressively twists the cookie open. Instructions for the tabletop device can be found here. They are marvelous, and I include them, because, you never know, you might want to try this at home.

So, what do you do after you’ve done a research study on Oreo cookies and built a 3D-printable Oreometer, to boot? Why, you publish a paper detailing your research.  On Oreology, the fracture and flow of ‘milk’s favorite cookie appears today in Kitchen Flows, a special issue of the journal Physics of Fluids.
