3184. Funny Numbers

title text: In 1899, people were walking around shouting '23' at each other and laughing, and confused reporters were writing articles trying to figure out what it meant.

Single panel comic. Four people (Bun, No hair, short hair, and pony tail) standing under a banner saying "Mathematical Society 2025 meeting" Bun asks "Any other new developments from the year to cover before we wrap?" No hair replies "Oh, the teens picked a new funny number." Short hair says "Aww, I'm glad they're still doing that." Pony tail says "I'll add it to the list", which they are writing on a board. The list has 23 (skidoo!), 42, 1,337 , 69 , 58,008 , 420, and the newest 67 with a circle around it.

Single panel comic. Three drawings of someone pole vaulting. In the first case the person is balanced on top of the rolling pole, which is the same height as the bar they have to vault over. In the second case the person is climbing a giant arched pole that goes over the bar. In the third case a person is rolling a giant pole that has its ends tied together to make a hoop. After pushing it to get a lot of momentum they cling to it as it raises them up and when they reach the top they let go and are flung across the bar. Lower caption: Fun fact: there are no limits on the length or diameter of the pole in pole vault.

title text: I'm trying to buy a gravitational lens for my camera, but I can't tell if the manufacturers are listing comoving focal length or proper focal length.

3181. Jumping Frog Radius

title text: Earth's r_jf is approximately 1.5 light-days, leading to general relativity's successful prediction that all the frogs in the Solar System should be found collected on the surface of the Earth.

Single panel comic. A small diagram showing a circle with a radius r subscript j f. On the outside of the circle there is a tiny from hopping from one point to another in an arc. It says "ribbit" and makes a "plop" noise when it lands. Next to the diagram is an equation to calculate r subscript j f , which is 2 * G * M divided by (4.5 meters/second) squared. Lower caption: More practically useful than the Schwarzschild radius, the Jumping Frog radius is the radius at which an object's gravitational pull is so strong that even a champion jumping frog can't escape.

3180. Apples

Three people (Bun, No hair, and Long hair) are standing around two piles of apples. No hair says "Okay, with my seven apples added to your five, we have...let's see...twelve apples!" Long hair replies "Incredible! Perfect agreement with the theory!" Lower caption: Experimental Mathematicians

title text: 'That's definitely above the catch-and-release size minimum for planetesimals.' 'I'm going to throw it back anyway.'

Single panel comic. Two people (Pony tail & Beret) are in a boat holding fishing poles. The water beneath them is very deep and there is a scattering of fish. The ground below the water is very rocky. Pony tail's line is drifting in the water. Beret's line has the hook stuck to a rock on the bottom. Beret says "It feels like a big one! At least 10 to the power of 24 kilograms!"

3178. Hyperacute Interdynamics

title text: Our models fall apart where the three theories overlap; we're unable to predict what happens when a nanometer-sized squirrel eats a grapefruit with the mass of the sun.

4 panel comic. 1. Two people at student desks while one person lectures. The lecturer says "Modern physics rests on three pillars. General relativity, which describes very massive objects," 2. Zoom to just the lecturer who continues "quantum mechanics, which describes very small objects," 3. Lecturer continues "And hyperactue interdynamics, which describes objects 10 - 30 centimeters in size and 200 - 700 grams in mass." 4. Comment from off panel student "The last one seems kind of limited." Lecturer replies "Yeah, but over its domain it's *really* precise. Absolutely nails squirrels and grapefruit. Someday we hope to unify it with the other two."

3177. Chessboard Alignment

title text: Luckily, the range is limited by the fact that the square boundary lines follow great circles.

explainxkcd: https://www.explainxkcd.com/wiki/index.php/3177

Single panel comic. Overhead view of three chess boards and the top of the heads of six players. All of the games are in progress with white on the bottom and black on top. In the middle board there is a dotted yellow line from the home square of the white queen on the bottom row to the last square in the top row (black home squares) on the right board, which contains a white queen. The player using white on the middle board has moved closer to the board on the right. Lower caption: It doesn't happen often because it requires micrometer precision, but if two chess boards are *perfectly* aligned it's actually legal to move pieces between them.

3176. Inverted Catenaries

title text: Some tires are marketed as 'all-shape tires,' but if driven in a climate with both inverted catenary falls and triangle falls, they wear out really fast.

Single panel comic. No hair and short hair are walking. There are a number of hemispheres falling from the sky flat side down, some of which have already reached the ground. No hair says "Oh wow, the first inverted catenary fall of the year! Time to swap out my all-season tires for square ones."
