Betulaster's image made me think "surely there is a version of this concept that's more polished." Turned out there were several different ones when I googled "self sculpting man". Many of them are sculptures that I suspect work best in person, but I liked this one.

Here's another one.

From Wikipedia: An Experiment on a Bird in the Air Pump is a 1768 oil-on-canvas painting by Joseph Wright of Derby, one of a number of candlelit scenes that Wright painted during the 1760s. The painting departed from convention of the time by depicting a scientific subject in the reverential manner formerly reserved for scenes of historical or religious significance. Wright was intimately involved in depicting the Industrial Revolution and the scientific advances of the Enlightenment. While his paintings were recognized as exceptional by his contemporaries...

I feel like photography (and in particular, photographs showing interesting physical systems) is a particularly good fit for "rationalist" artwork. For me, one of the top two or three most fundamental principles of rationality is entangling oneself with the world - living in the real world, and appreciating the real world, rather than escaping into one's own imagination. That's not to say imagination is bad, but rather that the role of imagination is to act on the real world, rather than to live on a separate plane of existence. Let the real world inform our beliefs, and use that knowledge to bring our ideas into physical reality.

Photography is a great fit for that, because it portrays physical reality. In some cases, a photograph can help us entangle our own beliefs with reality - as in scientific photographs, like an image of a cell with certain organelles stained. In other cases, a photograph can display the form of some brilliant idea made real - as in the photograph above.

Dr. Zbigniew Religa, a Polish cardiac surgeon, and a nurse, both exhausted after a 23-hour heart transplant; the first in Poland's history. (I don't know much about the story beyond that.)

It's a classic and has been featured on various lists of most influential photos. 

To me this photo honors technical mastery, perseverance and the miracle of modern medicine. 

Representing existential risks. A lost opportunity to grab the Reachable Universe (edit: /expand through the cosmos). (at least, that's my interpretation)

The map that blocks the territory 

What actually is the rationalist significance of this? It looks dope.

I chose this photograph because it displays one of the most elegant watch movements ever made. Within this movement there is a perpetual calendar complication. 

A perpetual calendar complication is a calendar feature within a watch that accounts for both short months and leap years. If you own a watch with a perpetual calendar complication, it would only have to be adjusted once every 100 years. 

Are the books that are visible in this picture actual parts of the library's catalogue, intended to be available for reading or borrowing, or are they just there for aesthetics?

(It seems like it must be the latter, for at least some of them.)

Illustration from Michael Haddad for Wired. It was originally commissioned for an article about biohackers, but I find that it captures the spirit of agency and self-improvement that is well-aligned with some of rationalist values. 

I find this a fascinating choice because of how not-rationalist Dr. Manhattan is for much of the novel.

I chose this picture both because I find its composition to be aesthetically striking, and for its portrayal of Piotr Wozniack, in deep thought and ready to jog (an activity which I personally find conducive to great thinking), someone who represents many of the traits I appreciate in a rationalist mind:

Wozniack wanted to learn as much as possible, as efficiently as possible, and ran into fundamental limitations with the capabilities of the human mind, without access to any technology that could help him overcome the barriers he faced. So he did the only r... (read more)

Is the sea a metaphor for something?

I hesitated a little on whether to post this, given that it has been pointed out that the curvature of a ringworld wouldn't actually be that obvious from the inside, so it's in tension with the spirit of rationality to post a picture that depicts something physically impossible.

Still, after almost posting this, then deleting it, then feeling like I wanted to post it anyway, I decided to just do it. As I feel that it captures a combination of joy and love of life co-existing  with, and made possible by, science and rationality.

I recommend the music as well as want to show the picture. 

Especially at 1:47:47 there is a piece starting that makes me cry every single time for the perfect coming together of ephemeral beauty and unstoppable determination.

I find that fitting, just like I find the look in her eyes fitting.

(Edit): This is no image that "describes" rationality and I know it. I find the emotional tone excellently encapsulates the "striving to be better", holding yourself to the highest standard and the like.
At the same time, listening to this it puts me, at least, in a... (read more)
