Supper vs. Dinner: Is There a Difference?

A linguist might be able to guess the general region you’re from based solely on what you call your evening meal. But as an article from Wide Open Eats explains, it isn’t just a matter of dialect. Dinner and supper really do mean different things—or at least they used to.

Historically, the word dinner was associated with the largest meal of the day, regardless of whether it was served in the morning, afternoon, or evening. The term comes from the non-Classical Latin word disjējūnāre, which is defined as breaking a fast.

Supper, on the other hand, is more time-specific. It stems from the Old French word souper, meaning an evening meal, and it's generally lighter than other meals served throughout the day. In other words, supper and dinner have more to do with the quantity of food that’s served than the time of day that you feast on them.

In the 1800s and perhaps even earlier, Americans in some rural regions started calling their midday meal dinner, while supper was reserved for the evening meal. This had more to do with occupation than location, though. In parts of the South and Midwest where farmers needed ample fuel to get them through the day, the midday meal was larger (hence the use of the term dinner). In the evening, supper typically involved a light soup, and the act of eating it was referred to as supping. Indeed, the word supper is related to suppe, the German word for soup.

This is still the norm in some parts of the U.S. As Wide Open Eats discovered through Google Trends, a search for “supper” is most common in Wisconsin, South Dakota, North Dakota, Minnesota, and Iowa.

This is also the case in some parts of the South. “If you grew up in the South post-colonial era, however, chances are your association with the words have more to do with colloquial etymology, rather than the time of day you sat down to eat,” Southern Living notes. “For example, you probably heard, 'supper’s ready,' just before Mama or Grandma placed a table-full of delicious dishes before you.”

However, supper is seldom used anymore—especially among younger generations—and dinner is by far the more popular term nationwide.

Do Lobsters Really Mate for Life?

It's a pop culture trope that mated lobsters stay together until they die. But is it true?

Nope. While plenty of animals practice long-term monogamy, lobsters are not among them. Lobsters actually mate by a weird system of serial monogamy. It's not exactly a one-night stand, but it's not a lifelong commitment either. Instead, a bunch of females take turns having a fling with the local dominant male that lasts a week or two and, if they're not happy with the amount of genetic material he's provided, then seek a little extra action.

It works like this: A female lobster who's ready to mate (which they can only do right after they've molted) hangs out near the den of the local dominant male and fans her pheromone-laced urine into his home. This relaxes the male, making him less aggressive and more receptive to mating. Then there's a brief courtship, and the male allows the female into his den.

Anywhere from a few hours to a few days later, the female slips into something a little more comfortable by shedding her exoskeleton. (Shacking up with the neighborhood tough guy guarantees her protection during this vulnerable time.) The pair mates, and the male deposits his sperm in the female. Once her new shell has hardened a week or two later, she takes off, and another female can have her turn. Often, the females in an area will stagger the timing of their molts to make their reproductive conga line more efficient. As soon as one female is done with the stud, the next one is already waiting to pee on his doorstep.

Sometimes, the male doesn't provide enough sperm to fully fertilize all of a female's eggs. In these cases, she'll leave before her new shell finishes forming to find and mate with another male (or males) until she collects enough sperm. Usually this requires just an extra dalliance or two, but as many as 10 have been reported.

Could an Astronaut Steal a Rocket and Lift Off, Without Mission Control?

C Stuart Hardwick:

Not with any rocket that has ever thus far carried a person into orbit from Earth, no. Large rockets are complex, their launch facilities are complex, their trajectories are complex, and the production of their propellants is complex.

Let me give you one simple example:

  • Let’s say astro-Sally is the last woman on Earth, and is fully qualified to fly the Saturn-V.
  • Further, let’s say the Rapture (which as I understand it, is some sort of hip-hop induced global catastrophe that liquefies all the people) has left a Saturn-V sitting on the pad, raring to go.
  • Further, let’s grant that, given enough time, astro-Sally can locate sufficient documentation to operate the several dozen controls needed to pump the first stage propellant tanks full of kerosene.
  • Now what? Oxidizer, right? Wrong. First, she has to attend to the batteries, oxygen, hydrogen, and helium pressurant tanks in her spacecraft, otherwise it’s going to be a short, final flight. And she’ll need to fill the hypergolics for the spacecraft propulsion and maneuvering systems. If she screws that up, the rocket will explode with her crawling on it. If she gets a single drop of either of these on her skin or in her lungs, she’ll die.
  • But okay, maybe all the hypergolics were already loaded (not safe, but possible) and assume she manages to get the LOX, H2, and HE tanks ready without going Hindenburg all over the Cape.
  • And…let’s just say Hermione Granger comes back from the Rapture to work that obscure spell, propellantus preparum.
  • All set, right? Well, no. See, before any large rocket can lift off, the water quench system must be in operation. Lift off without it, and the sound pressure generated by the engines will bounce off the pad, cave in the first stage, and cause 36 stories of rocket to go “boom.”
  • So she searches the blockhouse and figures out how to turn on the water quench system, then hops in the director’s Tesla (why not?) and speeds out to the pad, jumps in the lift, starts up the gantry—and the water quench system runs out of water ... Where’d she think that water comes from? Fairies? No, it comes from a water tower—loaded with an ample supply for a couple of launch attempts. Then it must be refilled.

Now imagine how much harder this would all be with the FBI on your tail.

Can a rocket be built that’s simple enough and automated enough to be susceptible to theft? Sure. Have we done so? Nope. The Soyuz is probably the closest—being highly derived from an ICBM designed to be “easy” to launch, but even it’s really not very close.
