The other 2 thirds of the Earth’s surface, obviously. As the greatest song in history says: “…We got no troubles - Life is the bubbles - Under the sea…”
- Comment on Speed 6 days ago:
In case you aren’t joking, I believe the relevant statement is that acceleration and “a change in velocity over time” are the same thing.
If you imagine driving a car forward in a straight line, pressing the gas will make you accelerate (velocity becomes more forward). Pressing the brake will also make you accelerate (velocity becomes less forward). Turning the steering wheel will also make you accelerate (velocity points more to the left/more to the right).
While I’m at it, you can do physics computations in a rotating frame of reference, but it produces some fictious forces, and gets really wacky quickly. An easy example is that anything far enough away from the axis of rotation is moving faster than the speed of light.

I built a scale model to prove the haters wrong. I had to tilt the platform a little for it to overcome friction, but once I did, the car rolled forward until it hit a wall.

Like today’s computer scientists, early biologists sucked at inventing new words, and simply reused existing ones. “Berry” in common language is a small, usually sweet and edible, fruit. Strawberries, blueberries, blackberries and raspberries are all berries.
Then biologists came along and decided, actually, strawberries, raspberries and blackberries are out, but watermelon and bananas are in, because the size of the fruit doesn’t matter, only the placement of the seeds decides whether something is a proper, scientific
berry.A similar thing has happened with “fruit” and “vegetable”, where scientific
fruitsinclude cucumbers, eggplants, and pumpkins. Luckily, all three of these are alsoberries.I say we ignore them, and use words to mean sensible things.
- Comment on this one goes out to the arts & humanities 5 weeks ago:
The (really, really, really) big problem with the internet is that so much of it is garbage data. The number of false and misleading claims spread endlessly on the internet is huge. To rule those beliefs out of the data set, you need something that can grasp the nuances of published, peer-reviewed data that is deliberately misleading propaganda, and fringe conspiracy nuts that believe the Earth is controlled by lizards with planes, and only a spritz bottle full of vinegar can defeat them, and everything in between.
There is no person, book, journal, website, newspaper, university, or government that has reliably produced good, consistent help on questions of science, religion, popular lies, unpopular truths, programming, human behavior, economic models, and many, many other things that continuously have an influence on our understanding of the world.
We can’t build an LLM that won’t consistently be wrong until we can stop being consistently wrong.
- Comment on If the agreed upon age of the Universe is updated from 13 billion years old to 26 billion years old how does that affect Science and Astrophysics? 1 month ago:
That estimate is based on assuming that the ratio of matter to light output is the same between galaxies 10 billion years apart in age. The high light output of these young galaxies could also be supermassive stars that burn out very quickly, larger stars typically forming faster than smaller stars, or many other things.
Blindly assuming a linear relationship between two things, then extrapolating is how you get the Windows loading bar circa 2000.
Separately, but just as big a potential issue, the data itself may be incorrect. Previous galaxies measured at extreme redshift values were remeasured, and found to have less extreme values. This can be as simple as there aren’t that many photons from these galaxies reaching us, so a short measurement period might not be enough to get an accurate picture.

Johns Hopkins University is named after the guy that funded it at the beginning, Johns Hopkins. He was named after his grandfather, Johns Hopkins, whose first name was his mother’s last name.
So Johns Hopkins has two last names, but one of them is a first name.

This is true unless you’re in Brunei, in which case 911 won’t work, and 991 is the correct number.

At the Walmart near me, there’s a whole set of checkout terminals intended for only a few items, but except for the absolute busiest times, they’ll put carts to block them off, including the ones in the regular self checkout area. There’s a line, but they physically remove access to some perfectly functional terminals just because.

Why have laws restricting bottles of wine to specific sizes in the first place? Surely as long as it’s labeled clearly it’s sufficiently easy to know what you’re getting.

Fruit as the basis for a measurement system? That sounds ridiculous. Use barleycorns like the rest of us!
- Comment on What future AI applications are you most excited about? 4 months ago:
I don’t think anyone will actually make it, but it would be cool to have an arrangement of accelerometers and microphones that you can put on the side of a packaged gift, shake it, and get a guess about what it is.
A harvesting robot that can tell how many days from ripe an avocado is, so the grocery store can have like… “ripe today” avocados, “ripe tomorrow” avocados, “ripe in 2 days” avocados. They’d come in small cardboard boxes, and they could just shift the boxes or signs over by one each day, and have more boxes if they get avocado deliveries less often.
Machine learning clothing/hairstyle/general fashion advice would be neat, but probably too open to manipulation to sell certain brands to be practical.
Tools to help developers put houses at the best spot on a lot, for things like water mitigation, tree safety, garden space in good sunlight, wind noise, and privacy.
Search tools that aren’t terrible on shopping sites, and news sites, and research journals and things. The days of “we asked Google to do it for us” being good enough are long over.

Everyone is mentioning the imaginary (and, presumably complex) number domains, but not quaterions and other higher dimensional number sets.
I’m going with defining a describeable number as any number that, given any finite period of time and any finite amount of resources, could be uniquely described to another entity with the ability to read and understand the language it is being described in, then saying all numbers are either describeable numbers (Despite the fact that these are almost laughably uncommon in the scheme of all numbers, I have diligently prepared an example: “2”), or indescribeable numbers (so much more common, and yet I can’t give even a single example).
