Poets say science takes away from the beauty of the stars — mere globs of gas atoms. I too can see the stars on a desert night, and feel them. But do I see less or more? The vastness of the heavens stretches my imagination — stuck on this carousel my little eye can catch one-million-year-old light. A vast pattern — of which I am a part…. What is the pattern, or the meaning, or the why? It does not do harm to the mystery to know a little about it. For far more marvelous is the truth than any artists of the past imagined it. Why do the poets of the present not speak of it? What men are poets who can speak of Jupiter if he were a man, but if he is an immense spinning sphere of methane and ammonia must be silent?

The strangest thing I noticed when I lived in SF was a lack of desire. Few people seemed to want something specific with a passionate intensity

Pope Leo XIV will use his Magnifica Humanitas to articulate a vision of the human person as a desiring creature—which is no surprise, given his Augustinian formation. "Our hearts are restless until they rest in thee." Now if only there had been a non-utilitarian understanding of Girard in Silicon Valley these past few years—or something like a book that tried to share an Augustinian understanding of mimetic desire and its teleology.

About once a month someone reminds me that “bees won’t build over religious images”.
Not to be a downer but…has anyone tried this with a control?
Could it just be the material of the picture?

@graciouswoodsy that's a really cool sand dollar print!

Teach your drone to fly the same way and you're halfway to making your very own bee-bot.

Step 2: secure the bag, accomplish the task, fly far away and do whatever you need to do. Maintain a path-integration estimate of where home is (green arrows)
Step 3: fly straight home. Go back towards home as efficiently as you can (orange arrows)
Step 4: final homing sequence. Accumulated errors caused you to slightly miss your target, but you landed within the initial learning flight zone, so you can get home based on the neural net trained on the original images (red camera sequence)

@McgregorJonryan same! i love jumping spiders but this was totally new to me

@rocketjohnsen Wow I've never seen this before. Very cool

@rocketjohnsen "At last, we've spent 6 years and $100m, but we finally have a demonstration of our newest X-ray emitter"

Don’t you hate it when you spend 6 years making a beautiful x-ray source and you learn that you could just be PEELING TAPE

you might have heard x ray emission from peeling adhesive tapes, now you know the best tape for it is tesa 64250.

@DanyBittel I was shooting manual, but there were some strong lights coming in from the window. I'll give it a go!

@rocketjohnsen Thanks.. I like your llama! The exposure seems to wander a bit, if you had auto exposure try PPISP.

@MemesEnds @bytheophana For sure! But even after 25 years at TI, he chose to build TSMC in Taiwan and not Texas. The comparative work ethic in Taiwan vs the US is one of many reasons he’s stated publicly, including TI’s unwillingness to fab chips for others and Taiwan’s willingness to invest in a new co

@rocketjohnsen @bytheophana Morris Chang went to university in the US and then worked at Texas Instruments. All the knowledge he acquired to found TSMC was from the US.

a cab driver in taipei told me that taiwanese tmsc workers universally dread going to america for business trips. he said that americans leave for happy hour while taiwanese people have to stay behind to finish their work. this makes them feel really uncomfortable and unhappy, like they’re second class citizens despite the fact that they come from HQ. sad and upsetting to hear, although unsurprising.
i asked him if those workers ever believe tsmc america will surpass tsmc taiwan. taiwanese consensus is that americans simply lack the work ethic and attention to detail to ever close the gap.
