Recovering academic now in public safety. You’ll find me kibitzing on brains (my academic expertise) to critical infrastructure and resilience (current worklife). Also hockey, games, music just because.

Why is the coronal section labeled "transverse" and the horizontal section labeled "dorsal"? That is some batshit fucking wrongness there.

DrBob ,

The figures I'm looking at call the dorsal plane "frontal" which at last makes sense. Dorsal and ventral would be their regular directions in the frontal plane. I'm a brain guy so I normally only deal with the things in the neuraxis.

DrBob ,

Dorsal plane still doesn't make sense to me as dorsal/ventral are the directions in the plane. In the same way it wouldn't make sense to describe something as the lateral plane if the directions are medial/lateral. But as I said I'm a brain guy.

DrBob ,

I'm genuinely not sure that anything has been invented in the 21st century.

DrBob ,

OLEDs were built in 1987 I saw my first VR demonstration in the 90s (and it wasn't cutting edge then). I saw my first AR demonstration then as well as part of an undergraduate engineering fair. And so on. I just looked up maglev trains - in commercial use since 1984.

I don't disagree that there hasn't been refinements, improvements, or commercialization of technology, but there hasn't been a technological leap or invention that I can think of in the 21st century.

DrBob ,

Your not wrong. But there are counter examples. I was going to use the example of the jet engine in my last answer as a true paradigm shifting development that had immediate impact. And in the mid-century period too! Or the first powered flight occurred in the first decade of the 20th century and had an immediate impact. The transistor and solid state electronics would be another example.

So let me flip it around and say we've had a quarter century without a major technological breakthrough. There's been progress, but it feels incremental. I spent a night with a physicist a few years ago who was arguing that progress is slowing because we are still relying on the exploitation of Newtonian physics. There are a few technologies that have made the leap to nuclear physics. But we've had the basics of quantum physics for a century now and haven't been able to exploit it in a useful fashion.

We had a 3d printer in the 90s at my Uni. It built layers with laser cut paper lol. It was the cheapest version available and it lived in the engineering department for rapid prototyping. This link says they were invented in 1981, metal sintering was added in 1988 and fused filament in 1989.

CRISPR is the closest we get It might be the honorary winner since it was wasn't fully exploited until the 21st century, even though it was cloned and being used in the 90s.

DrBob ,

Penis is derived from the Latin for "tail". As penis came to mean schlong over time, Latin switched to cauda. Dick only became a euphemism for the fuckstick in the 1980s. Why? I have no idea. But other proper names are/have been used including "Peter", "Johnson", and "John Thomas" that I can think of off the top of my head.

DrBob ,

Penis.

Cauda

DrBob ,

But we had Dick Nixon, Dick Cavett, and Dick van Dyke during that period.And lots more. So I don't think that's it.

DrBob ,

Detachable penis if you've never heard the song.

DrBob ,

This method is still superior to Heimlich. But its difficult to execute under most circumstances.

DrBob ,

OP misunderstood Kuhn maybe.

DrBob ,

I have no idea who this is and I am pushing retirement myself.

eta: she was the shop girl in Christmas Vacation when Chevy Chase went to buy lingerie. Also in NYPD Blue and Boxing Helena which I think was talked about more than it was ever viewed.

DrBob ,

You are missing the subtleties of this presentation that goes well beyond a histogram. This is a very nice layout that shows variability by month and decade.

DrBob ,

One useful function for AI would be to watch YouTube videos and extract any useful information into concise paragraphs. I am looking to be informed, not entertained.

DrBob ,

I am saying I am not watching the video. I would prefer a tight paragraph or two about whatever the videographer thinks are the extraordinary circumstances.

DrBob ,

Doing God's work.

DrBob ,

This is a really interesting visualization. I love the density of the data and the way it captures the year over year variability by month while allowing the annual variability to plainly stand out. This is really good.

DrBob ,

There are layers of variability there that can't be captured with a line plot. The data density is too high to even capture the decanal progression in a useful way, forget about monthly and annual variability . So no.

DrBob ,

My Leslie Nielsen.

Sticks and stones can break my bones,
But names can never hurt me.

DrBob ,

Michael Cohen got 3 years for his part in the scheme.

DrBob ,

Because sessional teaching for $4000 a course is a great way to make a living. I mean a 5 course load could move you close to the poverty line!

DrBob ,

If they said that, they're wrong. There are very limited circumstances that allow an appeal to the 11th circuit and she hasn't tripped those wires yet...mostly by not issuing rulings. Scheduling is not an appealable matter.

DrBob ,

It's not for either of those things. It's for cooking the books to hide the transaction. Falsifying financial records is the crime. And it would be a misdemeanor except that it was done to further a conspiracy to defraud the public which makes it a felony. It's not a crime to drive, but it is if it's a getaway car.

DrBob ,

He committed a criminal act to hide the source of the funds. He could have just paid her out of pocket and not told anyone. No crime then.

DrBob ,

So Greece has a problem. Well 👍

DrBob ,

This is part of my actual area of expertise. They mis-labeled the locus coeruleus as being "stress". Arousal would be more correct. They also missed Barrington's Nucleus right next to it which controls micturition. Absolute trash.

DrBob ,

It's real, but cobbled together from multiple sources. For instance we haven't referred to the "reticular activating system" since maybe the 1980s? They call it the "reticular arousal system" which is either a neologism or maybe a reactivation of the term in the literature. I haven't been active in the area in over a decade.

I'll note that this broadly accurate on a macro level, but the details really matter. There are different cortical layers for instance and cell types and the nature of the signal processing differs by layer. So saying "X connects to Y" is useful in some sense, but provides much less information than you might imagine.

DrBob ,

Well shouldn't it be? lol.

DrBob ,

There is actual work on that by a guy named Michael Persinger using transcranial magnetic induction. He claimed to have found a region where stimulation produced a sense of the presence/fear of God. Persinger was a hack on many levels. He used a motorcycle helmet with holes drilled in it for the induction mount. Lete see if I can find a paper...

We'll never mind. The kook died a few years ago. https://www.sudbury.com/local-news/breaking-laurentian-professor-michael-persinger-most-famous-for-his-god-helmet-passes-away-1016204

He also has a wikipedia page lol.

DrBob ,

It seems credible to me. 🤔

DrBob ,

Brown shoes with navy trousers has been on trend for 15 years now. It's become the default choice for business. Uniformed services will still require black. And a blue shoe with black trousers? WTF?

DrBob ,

Strangely they both look better.

DrBob ,

This is probably the worst of these kind of illustrations that I have seen. Notably the final panel is not the removal of systemic barriers but rather a use of resources to balance out disadvantage so that "equal" remedies are now a solution. There are problems in every panel though.

DrBob ,

Stop this bullshit. There is simply no comparison between the parties at this point.

DrBob ,

Infidelity by whom? I suspect that the actual answers are not symmetric among the genders.

Is a sound level of 105 decibels for a few seconds enough to rupture a person's eardrum?

In 2022, a Texas family filed a lawsuit against Apple for damaging their son's hearing after an Amber Alert went off while he was wearing Airpods. According to Google, the maximum volume of phone headphones is around 105 decibels. The family are claiming that the son now requires hearing aids after his eardrum ruptured....

eta: sorry - replied to wrong comment.

Sound pressure falls off as a function of the square of the distance. So if that jackhammer is 3 m away you are only receiving 11% of the sound energy that the operator is.

Ice bucket. We chill wine bottles.

God there was one where I bumped against the fridge and shifted a bunch of items that all showed up on my bill. I think a lot of the Disney hotels work on that system as well.

DrBob ,

Dude. It's even stupider than that. It sounds like cynical ignorance masquerading as profound clarity.

DrBob ,

There is no way to know wheher he spewed out that word salad without confirmation.

DrBob ,

I am also learning here, but I always thought that any short positions or intended divestures had to be part of the prospectus. Otherwise the principals are open to a flurry of lawsuits. Not that those would scare him.

DrBob ,

Jokes on you. I've had 4 already. Next one is 2026.

DrBob , (edited )

I am not an expert and this is not my area.

Another article this morning (I'll link if I can find it) said that a normal bond (construction surety etc.) follows the rules you laid out. There is specific language in NY legislation with extra requirements for court bonds.

eta:
https://www.cbsnews.com/news/donald-trump-175-million-civil-fraud-bond-valid-new-york/

"For court bonds, as regulated by the CPLR, the law is clear about in-state license requirement," said Pollock, who noted that there are surety bonds used in other industries like construction that would not be subject to that rule.
