That call at 12:04 though. ... "remind people that it still matters what family you were born into." 🤣 Love it!
don't forget "coronation" means "putting a hat on with an assistant" the monarchy are crap at that one job they have.
It really does, if you choose the wrong parents you can have a very rough life.
Yep condemned to doing the job even if you don't want it to some degree.
It great for tourism and internal merchandise sales. And provides some check on a out of control Parlement the one massive problem with Parliament week president systems which constitutional monarchy are. The "ruler" if they retain public respect to some degree with ability to call new elections can do so if the parliament goes stupid like Australia and Queen's Governor called new elections.
@@milferdjones2573 You're making wish we had something like that here in the US. 😂 The American 2 party system is garbage, but both parties in power would need to agree to change laws that allow other parties to have equal footing, so that's not going to change.
Well, adult IQ is ~80% genetic, while big 5 personality traits are 40-60% genetic. So yes, family matters are quite relevant.
Anyway, frankly getting money from lobbyist and oligarchs to run adds to get 50%+1 votes doesn't sound much more effective way of getting suitable candidate than hereditary monarchy.

Me, a blind person: "You have no power here!"
How good is your marksmanship then?
@@tarmaque It probably depends on how noisy you are!
Funny, I have never seen a blind robber. But, to be fair, you have never seen me either.
Yeah, the rate of armed blind robbers is getting way up there ...
@@bytefu Hahaha good one
And here I just finished knitting a sweater for the Milky Way for four arms!
Nice!
Well it does have 4 arms, but 2 are very weak, thus needing more sweater. Anyways, make sure its fluffy enough to reduce the impact of banging Andromeda .
Be careful that it doesn't collapse and forms a black hole.
@@tinkerduck1373 Ah yes. The 'ole "dropped stitches" gambit...

"Like most of us at the young age of 100 million, it also had far more frequent and violent outbursts" I'm so glad I found this channel
That comment in the video alone forced me to give her a like.
I don't know what's more dangerous, a thief with a gun pointed at you or a scared blind thief with a gun pointed vaguely in your direction
I wonder how long it takes until one of them wears a VR headset in pass-through mode for protection. Advantage for them: they can't be blinded anymore; disadvantage is they won't get the money because the other person is busy with laughing. 😂
@@tinkerduck1373 Presuming, like they did when the first motor vehicle hit the road, that the design will forever after remain the same...
Pretty sure they made a movie about this very idea...
Where I used to live in the high tech corridor known as Detroit, the cashier would be behind three inch thick bulletproof plexiglass.
Nobody ever tries to suggest laws to protect us from people with no criminal record, who are first time gun buyers, and could possibly pass any level of gun control applications and background checks, which society or law enforcement, or congress can come up with. A couple of the last few shooters fit this profile. Call in the remote viewers from Minority Report, and third eye spies, because that will be the next issue, when somebody decides to bring it up.
*Did I do that?"
~Steven Urkel
If you flash a bright light at someone who's pointing a gun at you, they are probably going to pull the trigger, not just run away (how do they find the door even?)
I also thought that was hilariously naive and idealistic
Yeah, I don't think they really thought this through.
I'm assuming the robber is mostly interested in getting the money. Most of them aren't interested in shooting anyone while walking away without money. To be motivated to pull the trigger, one must reason that doing so would lead to a successful robbery.
My hot take is that wearing sunglasses inside convenience stores will become forbidden. 😂
If the robber had their cap the other way around they would have been fine as well.
@@emalee8366 You don't need to have the intent of shooting anyone going in to rob a store. You're in a high stress situation and now you're startled, confused, and blind - that alone is possibly enough to start firing off shots in a panic.
15:34 holy crap, that robber must've imported his car all the way from 1990s Poland 😆
Sabine is getting progressively more enthusiastic when announcing that the "telephone will ring!"
So cute, isn't she.
One of the best channels out there
I love Dr. Hossenfelder's channel! Always informative and fascinating. You have to love her dry sense of humour.
What are the odds that Lightguard will induce the robber to drop his gun rather than fire it blindly?
Someone was watching the movie "Looker."
@@mikespangler98 : For those of us who haven't seen that box office failure panned by critics, how about explaining its relevance to my comment?
I figure it at least gives the clerk a better opportunity to retrieve his or her own gun and end the threat.
Or, alternatively, just get startled - I don't believe that is much of a stretch - and then flinch and pull the trigger without even really having wanted to
@@brothermine2292 Since you insist, the Looker Device uses a high speed series of flashes that freeze your nervous system for a few seconds. While you are effectively paralyzed the bad guy can do whatever and you can't stop him. Whatever includes pitching you out a window or throwing an undefended punch at you, or simply walking away leaving you alone at a crime scene.
You never cease to amaze me. And you have a very underrated sense of humour. There are others who are as informative, but the edge of humour in your presentations is just pure gold.
She's VERY german
Her sense of humor is so underrated that she has over a thousand people commenting on her videos, many of whom specifically point out how they appreciate her sense of humor.

And here I thought "nothing says legitimate transfer of power quite like putting a big clunky hat on someones head" was the killer line. Honestly, you can't expect to wield supreme executive power because some overdressed priest dropped a fancy hat on your head.

"Schrödinger, by the way, had a dog"... 😂😂😂😂😂😂😂
If I was pointing a gun at someone, and a bright flash of light appeared that blinded me, then in shock I might end up accidentally pulling the trigger. This seems like a horrible idea.
accidentally?
if you knew about that kind of system, it wouldn't be accidentally. it would be "if you dare to use those flash lights, I shot you. do you understand?"
Yes, even if the person with the gun had no active intent to pull the trigger, being blinded they would be more likely to feel imminently threatened and result in their firing. And while they wouldn’t be capable of aiming, they’d already be pointed in the right direction and I don’t feel that having a blind person blasting off wildly in my direction is necessarily an improvement over the previous situation.
XD i guess we are about to find out soon
Besides, everyone else in the environment will also be blinded, unnable to do much besides wait in the same room as the guy with a gun
It might reduce the casualty numbers from the insane plethora of mass shootings by gun obsessed citizens, (otherwise known by some idiots in the USA as a slight "mental health issue", but definitely NOT a "gun control problem). If an assailant is blinded in the first room, they may trip over one of the dead victims and hopefully break their neck. Of course, wearing a welders mask might reduce the effect somewhat? If politicians want to "make America great again", consider making safe as a first step.
15:50 - and meanwhile the cashier and any other customers are also temporarily blinded. Imagine the mayhem when the assailant reacts reflexively and just starts pulling the trigger.
These videos make me think there's still stuff that makes sense. I am dying out here.

hello, Sabine! I like your videos. you are my favourite physicist. I have one small request - could you please add links in the description? of course, I can search all by myself, but it would be very nice if you will add links on your sources.
Great suggestion!
Cathy is also good.
The opening scene of Touch Of Evil! Making both rats and AI's with good cinema taste is a program I can really get behind.
I was wondering if anyone else recognized that opening.
For those "smart" acronyms - you may be interested in the term "backronym" for acronyms where they came up with a smart sounding word and went backwards from there to make it fit.
When you look at what CEBRA stands for, it's pretty clear they didn't come up with CEBRA first and then try to come up words to fit the acronym. More than half the words don't fit, and they have to pull letters out of the middle of words to get CEBRA out of it. Backronyms are always much cleaner than that mess.
Loved the part about "king" Charle. I like my science alongside some witty sociopolitical comments.

Thank you for taking the time to bring knowledge to the common man.
Thanks Sabine, for another whimsical look at science!
A security system that only requires putting on a pair of shades/sunglasses to disable. Brilliant!
The system violates logic, as it evaluates to [Brilliant] AND NOT- [Brilliant] = TRUE
sunglasses are good for static light protection, not so much dynamic as occurs in a flashbang like event.
Alarm set for Saturday!

Thanks Sabine! Love your viewpoint

Link it to some kind of quantum pet shop in which the decay leads to either a cat or a dog being selected and placed in the box without you knowing, and you've then got a cat and a dog at the same time until you measure if it's a good boy.
im never sure if i give a fook so i have to check first to see what measurement says
@D R Are you thick or something mate?
@D R i feel like im in a state of superimposition where im both canceled and not canceled and i have to periodically check to see if my nudes or vulgar tweets have resurfaced
Catdog!
If one has a cat and a dog in a box at the same time the cat is dead and the dog's alive. Problem solved.
Never noticed before; good thumbnail strategy here! Thanks for thinking of us.
The movie clip used in the AI/mouse experiment looks like it’s from the beginning of Orson Wells’ 1958 film “Touch of Evil”. It’s the beginning of the movie in which a man plants a bomb in the trunk of the car driven by the father of his secret wife.
Vielen Dank! Your presentation makes science attractive and ever so interesting. That you pepper your lessons with jokes and I do laugh. Hypothesis: humour enhances data retention.
@6:50 "lightning sparked the production of molecules that form the basis of DNA and amino acids which are the building blocks of proteins."
Exactly how did the 4 bit information contained in DNA come to be from lightning or anywhere for that matter. And that's not even mentioning the principal of irreducible complexity.
Albert Einstein and Erwin Schrödinger are driving in a car. Thy hit a cat that crossed their road. Einstein stops the car immediately and asks: "Should look at the cat, if it is OK?" Schrödinger replies: "Are you mad? Do you want to kill it?!"
"ze cat was travelling 70mph towards me officer, from my reference frame i was a stationary observer!"

"he panics, drop the gun and makes a run for it"

Impressive how she didn't even flinch when the lightning struck.
I was just wondering how close we were to being able to print a chip board on a desktop printer with more or less regular paper and conductive ink. Doesn't look promising, but I'm sure it has other applications.
They sell silver pens now. You can draw a conductive trace on many surfaces. Mostly used to repair silver traces on plastic, like Zif connectors. Couldn’t they just use the same ink? At least for plastic surfaces and varnished circuit boards.
Flashing a bright light is a sure fire way to get any armed robbers to be highly stressed and trigger-happy.
Cool they invented a wall mounted defense flashlight. Thats brilliant. They should for sure go for a patent. Well the shop owner might not be pleased once he had to pay for the mother and 2 children that stood next to the attacker and got blinded. Could be a bit expensive once they panic by the flash or even being light sensitive (ever thought why the trigger warnings exist) and just fall over. So don't forget to install a very soft floor to limit the cost.
When we say something is in a superposition until it is measured, what do we mean by "measure"?
I would say, "to measure" means to get informations of an object/system.
Yes, that is exactly the problem. Quantum mechanics does not explain it.
@@SabineHossenfelder I would love to see a deep-dive of this "fat cat" experiment. How did they entangle the qubit with the crystal, is the crystal really in superposition, or is it just vibrating with two frequencies, how did they determine the superposition of the crystal, when does it collapse, etc.
@@SabineHossenfelder Then someone substitutes the word "measure" with "observe" and suddenly one standard Deepak is spontaneously created where you least expected it.
🐨An armed robber gets temporarily blinded by flashing lights, but what makes us think that the reaction to always result in him dropping his gun?🙄The experts are not concern that a robber may panic and start shooting in every direction?🙄And I'm assuming that the cashiers are only allowed to activate these lights when no one else are standing in close proximity of the robber🤔🐨
Love the information and the humor, always look forward to your videos
Tens of thousands of lumens? As somebody who works in that environment: That is very insufficient to temporarily blind somebody. The ten thousand lumen fixture (~100W power) on our wall at this height might be irritating, but direct sunlight is 100,000 lumens per square meter and you're still easily able to aim at a target that big at that distance with the sun right behind them.
Here we go folks - this weeks Science News!!
The Airbus Starlab was designed to fit inside a SpaceX Starship cargo bay so it could be launched to orbit in one piece. Starship might also be used to return a deconstructed ISS to Earth over several trips, rather than just crashing it into an ocean somewhere. This might actually end up being cheaper than using NASA's $1 billion "space tug" to crash the ISS, and you might also be able to visit the ISS in a museum afterwards.
Space museum? Nice idea
neat idea, but we're not to where space travel and cargo is a pedestrian thing. Space isn't boring yet, so novelty missions are probably not in the budget.
@@gibbsm NASA is already planning to spend $1 billion to safely de-orbit the de-commissioned ISS, while SpaceX is targeting a cost of $2 million per launch to orbit for Starship. We're talking about missions in 2031, which should give SpaceX plenty of time to meet their pricing and novelty goals. There have already been proposals from SpaceX to use Starship's large cargo bay and re-usability to help reduce junk in orbit, so the return of the ISS to Earth could just be one part of this effort. Costs could be kept low by returning junk to Earth in empty Starships that were used to launch unrelated payloads to orbit. Instead of returning empty after each mission, they would return with a cleanup payload if possible. This plan would give NASA money back from its $1 billion project, and it would prevent as much as 460 tons of junk being thrown into the Pacific.
Sabine, I love your humor and wit.

So the lights flash, the robber panics, fires his gun wildly, hits the cashier, runs blind out the door, remains blind for another 20 seconds or so then races away and the police arrive 9 minutes later?... Well at least they didn't get the contents of the register.

Something that has always confused me about the origin of life is the idea that it arose only once. I just find it almost impossible to believe that, when the conditions for the chemistry of life on Earth were perfect, it only happened the once. Even after getting my degree in palaeobiology, I've still never come across a satisfying answer to this problem.
It's a combination of 3 reasons:
- conditions for formation of life are also ideal conditions for life to thrive in
- life breeds exponentially
- a prototype organism is less fit than an organism that already has generations of evolution under its belt
Whatever life came first, it quickly depleted the "primordial ooze" and outcompeted any latecomers into extinction. It's not that life only occurred once - it's that life only survived once, because the greatest treat to survival is always the competition.
it probably didnt only happen once
might even still regularly happen
the problem is if you already have life, any new underdeveloped life springing up wont survive long before it gets nommed
Of course, the article is not discussing anything close to the origin of life. Only the origin of necessary building materials. It's like showing you can isolate a crystal structure of a metal and claiming you have found a possibility for the origin of clocks.
Well, todays life on earth is based on one single cell, because the genetic codes are all related, right? So selection threw out the other possibilities
@@Thomas-gk42 that's not how selection works for large, unrestricted environments. The success of one organism does not ensure the demise of others.
Apparently CEBRA stands for "Consistent EmBeddings of higher dimensional Recordings using Auxiliary variables". Is it just me, or are these acronyms getting very tenuous?
Its like coming up with a device that uses sound to detect things like planes and calling it a "detectoR thAt using waves to finD objects such As aiRcraft".
RADAR! It's genius!
8:36 This a beautiful conclusion! 👌
I always wonder if there was an information system before the modern genome. The researcher's approach would be akin to trying to find a natural process that generates an Nvidia graphics card instead of the humble first transistor.
You isolated individuals proteins, catalogued some properties about them, and gave them a name. It was extremely common (even with early genetics/genomics) for separate researchers to 'discover' a protein that had already been discovered and characterized by others (even 3+ times), which is one of the reasons many have/had multiple different names.
For example, many of the neurotransmitter receptor subtypes discovered ended up being the same one. That's why 5-HT (serotonin) receptor have gaps between #1-7.
Since we are all made of Stardust anyway ( all heavy elements being formed in suns). It's just one more leap to say those suns might be sentient and have printed out strands of DNA to shoot out in the universe when they go NOVA. Panspermia Astro style.
I've always wondered how the cat could be in a super position. Wouldn't the cat itself count as an observer and be able to see what's going on around it? Wouldn't it be able to see the poison that's with it in the box and know if it were dying or not?
its all philosophy, but "scientists" keep using it like its actually science. SMH. someday this idiocy will end and examples like this made up thought experiment will stop being used in the real world and then and only then real science can happen.
The cat itself always observes a collapsed superposition. If instead of poison, it was a blue or red light, first the light would be in a superposition of red and blue, then once the cat observes it there would be a superposition of a cat observing a red light and a cat observing a blue light.
You are correct, but the thought experiment is a hypothetical. As such, you can bend the rules for the sake of illustration. In this case, the cat is a passive entity, not an active observer.
@@BigMTBrain No, that is not correct in this instance. In the original formulation by Schrödinger, both the cat and the radioactivity detector are considered observers in the thought experiment. It was meant to illustrate that measurement collapse, according to Schrödinger, was poorly defined.
@@ObjectsInMotion this is because inside the cats brain was a miniature box and inside is a miniature cat with a miniature vial of poison and as such would be in a superposition of alive and dead states but for the ultraminiature box in the minature catbrain that contains an ultraminiature cat…. It’s basically cats all the way down.
Very nice episode
"Lightguard security system" is here to remind robbers to wear their cap the intended way!
"... so dis-arming..." Love the deadpan! I wonder how many people never get Sabine's jokes?
Isn't the cat the observer?
The cat observes a collapsed superposition
That is indeed the question scientists are trying to answer. What makes something an observer that collapses the wave function.
yes it's AN observer, but which observer are you referencing for your measurement?
@@ObjectsInMotion both you mofos do at the same effin time.

WHOA! That MRI scan decoding language from the brain - at 6:08 - is that real? Surely this is a whole new level of insight into the mind, consciousness and language? Is it replicated and peer-reviewed? It's amazing!
It uses technology extremely similar as the Text-to-image and chatGTP AIs that started being insanely good last year.
If I understand correctly, in this research they trained a chatGTP-like AI to understand language. This was used to limit the options for the 'decoded stimulus'. Then they used another machine learning system (decoder) to learn the relation between MRI images and words, or chatGTP activation (that part is not super clear to me).
For example, if they decoded the sentence "I have not understood this...", The chatGTP gives us likely words that are next: "paper", "research", "person" , "task" for example. Only for these words the likelihood that they were causing the brain activity was tested. So using this method the 'decoded stimulus' could never become a sentence like: "dog no a like yesterday to were that no". Because those words do not follow each other usually. If they did not use the chatGTP selection of words the decoder might give us sentences like that, which seems much less impressive.
What this research does show is that giving such constraints the meaning of the decoded sentences can go towards what the input really was better than chance level. Given that the sentence goes towards the real meaning, the chatGTP also makes it more likely the correct exact words are selected. So these two techniques reinforce each other a lot I think.
This decoder has to be trained per participant, which requires the participant to listen to stories for !16 HOURS! in the MRI scanner.
As a neuroscientist myself, I wouldn't say this reveals new level of insight into the mind, consciousness and language. It does show me that 1) we are developing complex tools that are able to show us what is going on in the brain. 2) We are collecting more training data per participant.
Using electrodes and MRI we already have measured neurons that are activated for certain vowels, certain percepts, certain actions. 11 years ago they were doing "Vision reconstruction using MRI" (search it on youtube). So this new research is not unexpected to me.
What I would say is I am certain our consciousness is our brain activity somehow.
So the sun worshippers might be right after all... 😉
