Even better, no straw. Sip it straight from the cup.
- Comment on Tell me the truth. 1 day ago:
That definition means a planet has nothing to do with physical state, and everything to do with the proximity of your neighbors. We could promote the Moon to a planet by pushing it further away, or demote Earth from being a planet by slinging it a bit closer to it’s hungry uncle Jupiter. We could demote all planets by extinguishing the Sun! Then the entire system stops working and it’s all just asteroid or something.
That arbitrarily chosen definition doesn’t describe the object, only it’s place in the malleable hierarchy. With this, the title of planet tells us nothing about the object itself, except that it’s orbit is only dominated by a star.
Even worse, the IAU definition is extra arbitrary, as it only counts objects that orbit specifically the Sun, so the vast majority of bodies in hydrostatic equilibrium that don’t fuse hydrogen aren’t planets. They also play very lose with hydrostatic equilibrium, as Mercury isn’t in hydrostatic equilibrium, yet is explicitly classified as a planet. And “clearing it’s orbit” is also rather indistinct, with no method to determine this is given. It’s up to argument if Neptune is a planet, as many plutoids intersect it’s orbit.
Even more worse, the barycentre of our solar system is sometimes outside of the sun! That means sometimes the Sun is co-orbiting with the rest of the solar system bodies, and therefore by this definition nothing is a planet! It’s a definition so arbitrary that it periodically stops existing!
I’m not just saying I disagree with the IAU here, but that their definitely is objectively poor, and poorly used. I agree that Pluto, Eris, Ceres, and many others should be in a different category from Jupiter, but make some categories that make sense, please!

Sounds like a sweat lodge. I don’t know how hot they get those normally.
- Comment on Tell me the truth. 2 days ago:
Pluto and Charon orbit each other. The barycentre (the center of mass they both orbit) is far outside of Pluto. The Earth-Moon barycentre is still inside Earth, though this could be changed by moving the Moon further out.
Either way, Earth, the largest rocky planet, could be made into a moon by sending it to Jupiter, so I don’t think being a moon should disqualify a celestial body from being a planet.
- Comment on Tell me the truth. 2 days ago:
There’s also plenty of classifications of plants based on form! Non-vascular plants, woody plants, herbaceous plants, algae and lichen…
Most of our “rocky” planets are pretty wet though. Mars is drying out, but Venus is caked with volatile chemicals and Earth is downright infected. Only Mercury is really barren, partly due to it’s small size. I could easily see three categories for gravitationally rounded bodies that can’t fuse hydrogen: Dry planets (usully smaller), Wet planets (usually larger), and Gaseous planets (gas giants).
- Comment on Actors that have been the least believable scientist castings, I’ll start. 3 days ago:
Yeah, in MIB he has Agent K to play off of. MIB 3, where he’s the sole driver of the narrative, was a weak entry partly because of this.
He has plenty of good movies and is an objectively good actor, but I think his style needs to be used well, and i, Robot doesn’t quite hit it. Maybe if Dr. Calvin was a stronger character rather than a worrywort and source of romantic tension, I’d like his performance more.
- Comment on Actors that have been the least believable scientist castings, I’ll start. 3 days ago:
Oh, that chemistry is great, but I don’t think he plays the investigator part well, especially when trying to follow the clues left by Dr Lanning. Will Smith’s style is very off the cuff and anti-authority, and while that works in MIB where there’s the very strict Agent K to play off of, I don’t think he works as the sole driver of a light mystery. Sonny and Spooner’s interactions are fantastic, but they’re usually driven by Sonny giving exposition. Spooner is usually just running from things as they unfold.
All in all, not a bad performance (there were plenty of objectively worse ones), but I don’t think it does the movie any favours. There are plenty of great things about i, Robot, but Will Smith is not one of them in my opinion.
- Comment on Actors that have been the least believable scientist castings, I’ll start. 3 days ago:
I don’t particularly like his acting style, completely outside anything he does as a person. iRobot and Men In Black are some of his better roles, but like Jeff Goldblum or Eddy Murphy, he can only play himself. I don’t think it works in iRobot that well though, but that’s more of a casting choice than bad acting.
- Comment on Seeing shit like this kills me. People are so ignorant. 3 days ago:
The crucifix is an implement of torture and execution, upon which the titular Christian god was executed to fulfill a blood oath. Executionists, torturers, blood magicians, nailers, death cultists, the forsaken (Psalm 22)…
Being shephered by a higher authority is also a common theme. Sheep is right there, although some actually use that directly.
Another common theme is the second arrival of their god, starting the end of the mortal realm and the death of all mortals. Death cultists again, apocalyptics, doomsdayers…
There’s lots of heinous things in their book, but most reject them or are unaware. You could call out lots of things there.

There were good parts in that movie, but Will Smith wasn’t one of them.

Blaschko’s lines happen mostly in mosaicism, where an embryo is formed by the fusion of two embryos, gets a mutation early in development, or otherwise gets two different genotypes. It can also be caused by X-linked genes. If those genotypes produce different skin colours or react differently to skin diseases, you can see the lines directly.
It looks like any visible form of mosaic disease may present along Blaschko’s lines.
- Comment on Black Holes 1 week ago:
There’s lot’s of issues with current physics, mostly in cosmology. String Theory was partly invented to describe the interior of a black hole. The characteristics of the Higgs field are still unknown. Gravity is still not unified with the other forces, despite appearing to couple with everything. Our current best models for the formation of the universe predict huge amounts of invisible matter, and we have no idea what that could be, from new particles to microscopic black holes formed in the first nanoseconds of the universe, to reinterpretations of relativity. Those same models also predict that out universe is dominated by strange energy inherent to space itself, which has no basis in the Standard Model at all. I wouldn’t call these perfectly fine answers.
And even if the nature of the interior of a black hole what the only issue, the final part of physics we haven’t explained, I would say we’ve thought that before. About a century ago, the scientific community though they had mostly solved physics. The last big question was why ultraviolet light didn’t extend out to infinite energy as predicted. Then photons happened and we discovered quantum physics.
- Comment on ‘It speaks to me in brain rot’: Theorising ‘brain rot’ as a genre of participation among teenagers 1 week ago:
As far as I can tell, brain rot encourages no thoughts, head empty enjoyment. It expects and promotes the lowest common denominator thoughts, like a thought stopping cliche but for entertainment instead of propaganda.
There’s plenty of mature brain rot and it’s only non-productive in the same way most media is. I can see calling it decompression-driven, but more as a form of escapist relaxation, like coloring books or knitting. It’s main focus is mininal mental effort, hence the name.
TL;DR: Ye, paper is garbo.

- Comment on I'm doing my part! 3 weeks ago:
Recycling paper (or not recycling) is far better than plastic is every respect. It’s not so much futility in this case so much as inefficiency.
Paper also is rarely, if ever, fully recycled, usually being downcycled into rougher and rougher materials like cardboard and egg cartons. No matter how well it gets recycled, it’s not going to displace primary production.
If you want to talk about futility here, the problem is way bigger than recycling. It’s consumerism, unrestrained capitalism, and ROI of power now vs power later. No amount of recycling of any quality will fix the world alonge but it is one step of many.

The manufacture of straws on that scale can’t be simple to ramp up though. Maybe they just speculated correctly on paper utensil production capacity?
Either way, there are opportunities for fast large scale change out there.
- Comment on I'm doing my part! 3 weeks ago:
Paper can be composted or burnt, and will decompose relatively quickly if dumped. I can’t see any post-use situation where paper is anywhere nearly as bad as plastic.
- Comment on I'm doing my part! 3 weeks ago:
It was a surprisingly fast change, to the extent that I wonder if they weren’t planning something along those lines as an industry wide PR stunt or lobbied industry takeover already. Or maybe paper straw machines are just really easy to setup.
It does show that widespread lasting change is possible. Even if it’s just a single step, we won’t get anywhere if we stop taking them.
- Comment on Let's get Physical 3 weeks ago:
Some kind of drama, probably of the affair kind, but who knows? Maybe it was just a great reaction to a jump scare out of a loving couple. Maybe it was people at a zoo getting manured by a rhino.
These two stills are the only context I have. I’ve seen them twice in the same day, so it’s probably topical, but it could be from the 90s and made relevant by a certain list or something.
My first thought was certain politicians getting freaky in a puplic theatre on security cams though, so not too far off.

- Comment on This comic hung in my office for years 4 weeks ago:
I wouldn’t say a normal CPU is inefficient at graphics or cryptography, rather that a specialized GPU is particularly efficient at those tasks.
We only consider a CPU slow at these tasks because of how much faster a GPU is with them, but we never see how much worse a GPU is at general conputation tasks, because of how stupendously bad it is.
As soon as operations need to share info, the GPU speed advantage is gone. Branching paths bog a GPU down with redundant execution. Latency is quite poor too. And exceptions & interrupts are basically impossible at the system level. Trying to run normal programs on the GPU would be a disaster.

And adding more fuel to a fire make it burn hotter and faster. Largers stars die faster, so more fuel will reduce the lifespan.
- Comment on the universe about to have a little minty b 4 weeks ago:
That suggests we can change the superposition collapse distance by changing how much were observing. By measuring the proportion of change as we turn on or off large-scale observation systems, we can calculate how much of the universe is being loaded by other users. We can finally start solving the drake equation!
- Comment on I'm not saying Lamarck was right; I'm just saying being an absolute unit probably isn't in the average human's genome 4 weeks ago:
Genes aren’t the only inherited trait. Environment, wealth, culture, and ideas are also roughly passed down to offspring, but these can’t modify the genome, only the gene expression.
Of course it gets way more complex as these things do change fitness which does apply evolutionary pressure to the genome, but you can’t get bigger muscle genes by working out.
That is to say, there are some Lamarckian effects, but it’s all by Darwinian mechanics.
