title text: Karpov's construction of a series of increasingly large rice cookers led to a protracted deadlock, but exponential growth won in the end.

(xkcd.com/2936)
(explainxkcd.com/wiki/index.php)

3 panel comic.

1. Black hat says "Exponential growth is very powerful" to No hair.

2. Zoom in to Black hat and a drawing of a chess board with little ovals in the squares, 1 in the first, 2 in the second, 4 in the third, 8 in the fourth. Black hat says "A chessboard has 64 squares. Say you put one grain of rice o the first square, then two on the second, then four, then eight, doubling each time"

3. Black hat is standing at a table pouring rice onto it. There are sacks of rice next to the table. Buzz cut is walking away from the table. Inset text: If you keep this up, your opponent will resign in frustration. It's called Kasparov's grain gambit. Nearly impossible to counter.

title text: ==COSMOLOGY==> 'Uhhh ... how sure are we that everything is made of these?'

(xkcd.com/2933)
(explainxkcd.com/wiki/index.php)

Single panel comic.

A flow chart starting with a single box. The box has no hair saying "Everything is made of tiny particles. If I understand those, I'll understand everything!" and a small vibrating particle. 

The two arrows leading from the box are labeled condensed matter physics and quantum field theory.

Condensed matter physics leads to a box with no hair going "Oh no. Simple particles can combine to produce complex behaviors." and looking at a number of smaller particles vibrating in a star shape.

Quantum field theory leads to no hair looking at the same vibrating particle and clutching their head and saying "Oh no. These particles aren't simple!"

Title: Driving PSA: Random drivers can't grant you the right of way as a gift.

Above the first car there is a bubble that says "You go ahead! I'm feeling generous." That car is labeled "Time traveler pretending to be polite"

There is a car approaching the intersection northbound in one of the through lanes. This car is labeled "Car that they are waving you into the path of"

Lower caption: If someone waves you out, assume they are an assassin sent from the future to kill you and make it look like an accident.

(xkcd.com/2930)
(explainxkcd.com/wiki/index.php)

Single panel comic.

Plot with the X axis showing time from 2005 to 2024. The Y axis has no units or labels. Plot is labeled"Google trends search traffic for 'solar flare'"

The graph has a low line with a few small wiggles from 2004 to 2011, at which point is spikes and decreased in 2013, though it doesn't quite go back to the original baseline. There are smaller spikes in 2015 and 2018. There is a steadily rising trend starting in 2021 through the present. There is a mark showing 11 years from the peak in 2012 to 2023.

Lower caption: I like that google has existed almost long enough for us to observe the solar cycle using google trends.

@xkcdbot "Blowout" - a simple solution to a simple problem...

An xkcd cartoon with a user-built solution called "blowout," consisting of a cement block in the middle of the frame that causes dropped yellow balls to bounce briefly, where a left-facing fan blows them just hard enough to rebound to the left, drop off the block, and fall into the grinder wheel at the bottom of the frame

The X-axis has 9 tick marks, the Y-axis has 6. Neither has units.

The curve starts well below Y = 0 at X slightly less than 1. It increases rapidly to ~6 when X reaches 2. It slowly drops off to about Y = 1 by X = 7.

50,000 - 20,000,000 at least stay on the *surface* of the star instead of diving down to the core

20,000,000 - 10,000,000,000 you know, you could've picked a normal star instead of one that's exploding

 10,000,000,000 or higher I hope you're enjoying your visit to the Big Bang, but you should really come back home immediately

Single panel comic with 4 sub-panels.

Across the top is a graph with a y-axis labeled "my apparent age" and an x-axis representing time. It is a flat line about three quarters of the way up the axis until the middle of sub-panel 3, where it dramatically drops by 20 years and then rises logarithmically by 7 to 10 years at the end.

Sub panels are drawn below the graph from left to right.

Sub panel 1: No hair sits at a desk in front of a computer. There is a dark window in the background.

Sub panel 2: No hair turns and sees 3 faint white flecks in the window.

Sub panel 3: The window now has a significant number of snow flakes visible. No hair is jumping out of the chair and yelling "Hey! It's snowing! Outside! There's snow falling! Look! Snow! Hey!" 

Sub panel 4: The window has slightly more snow visible. No hair is back at the computer, though their head is angled such that they are not paying at much attention to the computer as they did in sub panel 1.
