44, he/him | Back off man, I'm a scientist.

This video is a very good summary of the reasons why some chemical elements have no stable isotopes, and why the most recently discovered elements have had to be produced synthetically. 

In particular, the elements corresponding to atomic numbers 43 and 61 were gaps in the periodic table for a long time, because they have stable isotopes.   Technetium and promethium were eventually discovered, but only by transmuting other elements into them.  While Tc and Pm are formed in stars, just like other naturally occurring elements, any natural Tc and Pm on the Earth would have decayed into other elements a long time ago, so there’s none left to find.

The same holds true for the transuranic elements, i.e., the ones heavier than uranium.  Those all had to be discovered synthetically as well, and I think that’s easier to understand because they represent this outer fringe of nature.  Bigger atomic nuclei are just harder to keep together for any practical length of time.  But techentium and promethium don’t have that problem, so why do they have no stable isotopes?

The answer has to do with rules surrounding atomic nuclei, and while these aren’t fully understood, we know enough to understand that certain numbers of protons and neutrons in an atomic nucleus are more stable than others.  Odd numbers of protons, for example, are less favorable than evens.   That’s why uranium (Z=92) lasts longer in nature than neptunium (Z=93).  Elements with odd numbers of protons can still work though, if there’s a small enough number, or if there’s enough neutrons to compensate, or if... some other stuff I’m not sure I understand. 

The problem with technetium and promethium, though, is that an atomic nuclei with 43 or 61 protons is just an untenable situation.  They’re odd numbers, for one, but they’re also odd numbers that happen to make all the other rules unfollowable.  It doesn’t matter what number of neutrons there are in these guys, because you end up breaking too many stability rules.  So that means no stable isotopes.  They talk about “magic numbers”, and it’s mentioned in the above video too, and I want to say 43 and 61 are called “anti-magic numbers” in nuclear physics, but I might be misremembering this. 

Anyway, this was always something I’ve been interested in, and sort of vaguely understood, but not well enough to explain, so I’m pleased that PBS could cover it so elegantly.

guy who does unboxing videos but he only talks about the boxes

"Hey, everyone, welcome back. Our first box today is a Uline nine by five by four. Single piece of clear shipping tape over the top, two inch, and the UPS label nicely centered. No edge tape, and you know, that's fine. This box is pretty light, I'd say under a pound, and taped edges don't really add much stability here. Let's open it up and see what we've got for dunnage...okay, half-inch bubble wrap, that's unusual in a box of this size."

Sometimes a post throws into perspective just how much niche knowledge you possess.

I read this, and I can tell from the “review” that the package was NOT shipped by a professional.

One: two inch tape. Professional establishments use three inch. It’s MUCH easier to seal boxes with, especially around the edges. Two inch is what you can buy from office depot or lowe’s. It’s fine for moving house, but it’s definitely not professional grade.

Two: no edge tape. Just seal your edges, people. UPS basically plays soccer with your packages. Even the light ones, just on principal, give them the structural support you can offer.

Three: centered label. Looks pretty on a package, sure, but it makes it very likely that the label will be covered up when the box is sitting in a stack or a pile, and that increases the chance that it will be manhandled to get to that label or even potentially mis-scanned or missed altogether in a stack. Label the SIDE of the box if at all possible! And put it to the side if you can’t! Visibility!

Also, the reviewer may be accustomed to getting a lot of boxes, but I don’t think they were a professional shipper, either. Someone who has shipped too many boxes would comment on whether the box was new or reused, whether there was any special hazmat (mostly lithium-ion battery) labeling, the condition of the package post shipping, and whether or not the weight of the package matched the stated weight on the label. AND they’d have commented on the two-inch packing tape.

I don't know what to say other than "your experiences are not universal," because I do shipping and receiving at a machine shop for a living, I see packages sent by professional shippers all the time, and I disagree with you on just about every point.

One: two inch tape. Professional establishments use three inch.

Nope. For packages I see, two inch packing tape is the norm. Today I had one package with three-inch water-activated reinforced paper tape and one (from Uline) with 2.75" packing tape. Everything else used 2" packing tape. Yes, it's exactly the same kind of stuff that you can get at Office Depot or Lowe's, and people use it because it gets the job done.

Two: no edge tape.

Not uncommon for small, light packages. I just don't see box failures on packages under a pound where more tape would have helped. Where I do see failures is overloaded boxes, thirty pounds and up, where the corrugate simply ripped, and no amount of tape would have saved the package.

PSA: please don't fill an 8x8x6 single-wall box with machine screws and expect it to arrive intact. Fastenal, I'm looking at you.

Three: centered label.

Label on top is standard. I had only one box today with the label on the side, and all the rest on top.

Looks pretty on a package, sure, but it makes it very likely that the label will be covered up when the box is sitting in a stack or a pile, and that increases the chance that it will be manhandled

Your package will get manhandled, regardless of where you put the label. Plan on it.

to get to that label or even potentially mis-scanned or missed altogether in a stack. Label the SIDE of the box if at all possible!

Heck no! I expect labels to be on top and that's the first place I look for them. If it's on the side, that's potentially four other places I have to look, which is a pain in the ass when I'm busy. And I'm always busy.

UPS, incidentally, says you should put the label on the largest surface. For the packages I get, that's usually the top.

Someone who has shipped too many boxes would comment on whether the box was new or reused,

Okay, that's legit. I do see a fair number of reused boxes.

whether there was any special hazmat (mostly lithium-ion battery) labeling

Hazmats aren't common enough to mention it every time when there isn't one present. (My hazmats are usually solvents or paint, and that's not something I get every day.)

the condition of the package post shipping

Not usually noteworthy. My internal monolog (which is what the above fanciful review is based on) doesn't bother to mention it unless something unusual happened to the box.

whether or not the weight of the package matched the stated weight on the label

Although I ship just as many packages as I receive, if not more, it never would have occurred to me to check. And I don't have a scale in the receiving department, so it would be guesswork anyway.

AND they’d have commented on the two-inch packing tape.

Which everyone uses. There's not much need to comment when it's far and away the most common type of tape.

Perhaps things have been different for you, but this is how it is in the manufacturing industry.

The only thing you check for is if someone else already asked for PTO in the same slot. That's it.

My department fell apart 2 weeks ago when I took my PTO. we were already short handed, someone quit at the start of the week, and there was literally nobody to even call in to cover, so they were fucked. But that's on corporate for refusing to hire enough people. That's on corporate for thinking we need no overlap in our shifts, no midday people . That's not my fault that I needed a specific week off, or even if I just WANTED it off. Businesses know what they need to do, it's not on me to make things easy for a billion dollar corporation that doesn't even give a shit about my store.

Word of advice kids: Don't take workplace advice from someone who uses Scrooge McDuck lighting a cigar with a bank note as their user icon.

If the whole place falls apart because I need a week off, then I'm clearly not being paid enough since I'm clearly extremely essential to having a functional store. If I'm not, then give me a damn week off

As someone who's been in the workforce for decades, I can assure you that your employer will not be grateful for you "minimizing disruption". That's because they just take it for granted that you'll be there no matter what. If anything, leaving the team in a lurch shows them how much they depend on you.

It *is* worth trying to pick PTO dates to avoid screwing over your coworkers, but that's kind of your boss' job, though. They're supposed to have a plan for this stuff, and you being super-flexible just gives them an excuse to never make a plan.

It's easy to think that gutting it out will make your employer appreciate you more, and in the short term it might, but I've found that managers tend to get shuffled around often, and sometimes the one you really impressed isn't even around to put in that good word for you when you need it. In the end, you may get let go simply as a cost-cutting measure, and your exemplary performance never even enters into it.

That's not to say hard work is never rewarded, but there's diminishing returns to it. I once pulled a 24-shift because I was young and stupid and thought it was important enough to the business, and all I got was a handshake. Three years later they showed me the door. I can't even tell that story in job interviews as like my "proudest achievement" because I doubt anyone would believe it. Also, I wouldn't want to work for a place that would have me do that again. So in the long run, I never should have done it.

Same goes for PTO. If you choose not to take a certain day off, no one will even care, since they'll just assume you'll be taking it later. If you just never use it, your employer just assumes you didn't want it. At no point do they think "Wow this guy's a team player, let's give them a raise!" It just doesn't work that way.

I mean, I guess Scrooge McDuck never takes a day off, but his "job" is just screwing around all day having adventures and swimming in loose change. Every day is summer vacation for that dude.

Don’t you forget about me

When one of Eric Täuscher’s PhD students arrived at the lab one morning and discovered she had left a TLC plate in an iodine chamber overnight, she could have simply thrown it out. But something compelled her to take a close look at the neglected plate. When she did, she noticed the tiny crystals growing from the plate, the product of the iodine in the chamber reacting with the plate’s aluminum backing. The crystal growth had also caused the silica on the front of the plate to lift off in delicate flakes. Intrigued, she showed it to Täuscher. He also found the corroded plate strangely beautiful, so he snapped a photo.

Täuscher’s lab at the Ilmenau University of Technology studies fluorescent organic molecules for pH, temperature, and ion sensing applications. The student had been running the TLC to try and identify a mysterious non-UV-absorbing byproduct of a reaction. It took her all of ten minutes to redo the plate. ⁠— Brianna Barbu

Lurking in the corner

Cleaning out the corrosives cabinet isn’t many people’s favorite lab chore, but after finding this decomposing container of hydrobromic acid (HBr), Mark Olson was glad his group got around to it. Olson is a chemistry professor at Texas A&M University-Corpus Christi, where he researches soft matter, nanoscience, and supramolecular chemistry. Glass reagent bottles are sometimes shipped in steel cans like this, surrounded by padding. “I am not sure how long the bottle sat there,” he says. “It was sitting towards the back behind a much larger bottle of another substance, easily out of view. What became clear once we began to clean it up was that the bottle inside the unopened can had somehow ruptured and was leaking,” he says.

The brown material is iron bromide (FeBr2), a relatively benign substance that formed as the acid leaked and reacted with the steel container. And the cabinet was properly vented, Olson says. Nonetheless, Olson says, they carefully moved the whole mess into a fume hood, took it apart, and disposed of everything in appropriate hazardous and chemical waste containers. In this case, the can corroded from the inside out, Olson says, but because other chemicals in the corrosives cabinet react with steel, whoever took delivery should have opened the can and placed just the bottle of reagent in with the others. “Opening the can immediately after delivery to the lab might have shown that the bottle cap had failed,” he adds.  —Craig Bettenhausen

This video about imaginary numbers caught my attention, and it turned out to be even better than I expected, drawing a through-line from quadratic equations to the Schrödinger equation, which is extremely fundamental to chemistry and physics. 

Years ago, I tried to study group theory as it relates to molecular symmetry, and in working the problems, I ended up running into the same mathematical principles, usually stuff tied in with Euler’s constant and the golden ratio.   I probably ended up learning more about mathematics than I did about chemistry that year, and I feel like I forgot most of it, but this video illustrates why e and i keeps coming up in anything that has to do with molecular orbitals.   Those are wavefunctions, and Euler’s formula contains both the sine and cosine wave.  

One of these days, I’d really like to study the Schrödinger equation in depth, because it’s always frustrated me how it’s so important when it just looks like a bunch of characters around an equals sign.  I don’t know when I’ll have time to really get into it, but this video gives me some confidence that I can do it.

I know it's sand but I want to eat it

Good news it's not sand!! It's rice flour!! During deepavali, Indians make rangolis which is shown in the video!

there's a CHANCE it's rice flour and there's ALSO a WAY HIGHER chance it's sand, quartz, glitter, powdered chalk, sawdust, talcum, etc. even if it's flour the dyes aren't edible probably.

DO NOT EAT RANGOLI.

I'M INDIAN.

Happy Diwali! Please do not eat sand!

absolutely obsessed with the way Fahrenheit is legitimately a superior temperature measurements for day to day life than celsius (more precise, accessible, and understandable) but ppl refuse to admit to it bc they’re so caught up with the “silly americans refuse to convert to metric” gag

fun little info graph I found

[id: three identical number lines with 0 at one and and 100 at the other, labelled “Fahrenheit” “Celsius” and “Kelvin”. The ends are labelled, respectively:

Fahrenheit: Really cold outside - Really hot outside Celsius: Fairly cold outside - Dead Kelvin: Dead - Dead]

OP, it's only more useful for Americans because you're not regularly boiling water.

0° Celsius gets you ice. 100° Celsius gets you tea.

It's a very simple system.

Genuinely fascinated by this world in which Americans don’t boil water on a regular basis and a thermometer is necessary to know whether water is frozen or boiling.

Fuses

My microwave quit working on me the day before yesterday, and it seemed an awful lot like a blown fuse.   The outlet still worked for other things, and not even the clock would come on when I plugged the microwave into a different outlet. 

I’m familiar with this sort of thing because I’ve dealt with it before in my job.  You go to run an instrument and it’s just dead, until you swap out the fuses inside of it. Usually, there’s a little compartment or slot in the back where you can get at it easily. 

The internet agreed with my reasoning, so I thought, well, this is no different from any other machine, I might as well open up the microwave and try to fix it myself.   The only real difference was that they made the fuse a lot harder to get at. 

I mean, it’s easy to find.   You just remove the cover and there it is on the top.   And there’s only one, so it’s not like I have to guess which one to change.  What irks me is that I have to remove the entire cover to get to this point, and two of the screws were a weird kind that wouldn’t work with any of my screwdrivers.   I think this was a safety feature to prevent people from doing what I was doing, but I ended up just torquing them out with a pair of pliers.    I also pinched my finger while doing this, so I wish Sunbeam would have just used regular screws and saved me some trouble.

Also, when I watched videos on how to change a fuse in a microwave, I learned that there’s an electrical hazard from the capacitor.  Even when unplugged, the capacitor can still store enough power to kill you if you touch it.   So you have to discharge it before doing anything else.  I found several guides on how to do this, but this guy had the coolest hair, and his needlenose pliers looked like the kind I have, which was reassuring.

Basically, you touch each jaw of the pliers onto each of the two leads at the same time, and make sure you’re only touching the rubber coating on the handle, and that will make a spark and discharge the thing.  Mine didn’t spark, because I left it unplugged overnight, and apparently that’ll do the trick too.   I went ahead and used the pliers anyway out of an abundance of caution.  

I guess the thing that annoys me is that I should even be dealing with the capacitor in the first place.  I suppose I’d need to discharge it no matter what, or I’d get bitten while trying to remove the fuse, but I feel like they could have designed it so that the fuse could be popped out without touching it, like this thing:

Image

I’ve worked with this kind of dealie before.  You just turn it with a flathead screwdreiver and it pops out.  You replace the fuse inside, pop it back in, and screw it back into place.   Maybe that’s not practical on a microwave oven, or they just don’t trust the general public to have this sort of access to fuses. 

Anyway, I got the old fuse out, so now I just gotta go to the store and get a replacement and see if that fixes the problem.   If it doesn’t, I guess I’m just buying a whole other microwave, because that’s about as far as I dare to venture into the electrician’s world.

Why Smart People Believe Stupid Things

If you’ve been paying attention for the last couple of years, you might have noticed that the world has a bit of a misinformation problem. 

The problem isn’t just with the recent election conspiracies, either. The last couple of years has brought us the rise (and occasionally fall) of misinformation-based movements like:

  • Sandy Hook conspiracies
  • Gamergate
  • Pizzagate
  • The MRA/incel/MGTOW movements
  • anti-vaxxers
  • flat-earthers
  • the birther movement
  • the Illuminati 
  • climate change denial
  • Spygate
  • Holocaust denial 
  • COVID-19 denial 
  • 5G panic 
  • QAnon 

But why do people believe this stuff?

It would be easy - too easy - to say that people fall for this stuff because they’re stupid. We all want to believe that smart people like us are immune from being taken in by deranged conspiracies. But it’s just not that simple. People from all walks of life are going down these rabbit holes - people with degrees and professional careers and rich lives have fallen for these theories, leaving their loved ones baffled. Decades-long relationships have splintered this year, as the number of people flocking to these conspiracies out of nowhere reaches a fever pitch. 

So why do smart people start believing some incredibly stupid things? It’s because:

Our brains are built to identify patterns. 

Our brains fucking love puzzles and patterns. This is a well-known phenomenon called apophenia, and at one point, it was probably helpful for our survival - the prehistoric human who noticed patterns in things like animal migration, plant life cycles and the movement of the stars was probably a lot more likely to survive than the human who couldn’t figure out how to use natural clues to navigate or find food. 

The problem, though, is that we can’t really turn this off. Even when we’re presented with completely random data, we’ll see patterns. We see patterns in everything, even when there’s no pattern there. This is why people see Jesus in a burnt piece of toast or get superstitious about hockey playoffs or insist on always playing at a certain slot machine - our brains look for patterns in the constant barrage of random information in our daily lives, and insist that those patterns are really there, even when they’re completely imagined. 

A lot of conspiracy theories have their roots in people making connections between things that aren’t really connected. The belief that “vaccines cause autism” was bolstered by the fact that the first recognizable symptoms of autism happen to appear at roughly the same time that children receive one of their rounds of childhood immunizations - the two things are completely unconnected, but our brains have a hard time letting go of the pattern they see there. Likewise, many people were quick to latch on to the fact that early maps of COVID infections were extremely similar to maps of 5G coverage -  the fact that there’s a reasonable explanation for this (major cities are more likely to have both high COVID cases AND 5G networks) doesn’t change the fact that our brains just really, really want to see a connection there. 

Our brains love proportionality. 

Specifically, our brains like effects to be directly proportional to their causes - in other words, we like it when big events have big causes, and small causes only lead to small events. It’s uncomfortable for us when the reverse is true. And so anytime we feel like a “big” event (celebrity death, global pandemic, your precious child is diagnosed with autism) has a small or unsatisfying cause (car accident, pandemics just sort of happen every few decades, people just get autism sometimes), we sometimes feel the need to start looking around for the bigger, more sinister, “true” cause of that event. 

Consider, for instance, the attempted assassination of Pope John Paul II. In 1981, Pope John Paul II was shot four times by a Turkish member of a known Italian paramilitary secret society who’d recently escaped from prison - on the surface, it seems like the sort of thing conspiracy theorists salivate over, seeing how it was an actual multinational conspiracy. But they never had much interest in the assassination attempt. Why? Because the Pope didn’t die. He recovered from his injuries and went right back to Pope-ing. The event didn’t have a serious outcome, and so people are content with the idea that one extremist carried it out. The death of Princess Diana, however, has been fertile ground for conspiracy theories; even though a woman dying in a car accident is less weird than a man being shot four times by a paid political assassin, her death has attracted more conspiracy theories because it had a bigger outcome. A princess dying in a car accident doesn’t feel big enough. It’s unsatisfying. We want such a monumentous moment in history to have a bigger, more interesting cause. 

These theories prey on pre-existing fear and anger. 

Are you a terrified new parent who wants the best for their child and feels anxious about having them injected with a substance you don’t totally understand? Congrats, you’re a prime target for the anti-vaccine movement. Are you a young white male who doesn’t like seeing more and more games aimed at women and minorities, and is worried that “your” gaming culture is being stolen from you? You might have been very interested in something called Gamergate. Are you a right-wing white person who worries that “your” country and way of life is being stolen by immigrants, non-Christians and coastal liberals? You’re going to love the “all left-wingers are Satantic pedo baby-eaters” messaging of QAnon. 

Misinformation and conspiracy theories are often aimed strategically at the anxieties and fears that people are already experiencing. No one likes being told that their fears are insane or irrational; it’s not hard to see why people gravitate towards communities that say “yes, you were right all along, and everyone who told you that you were nuts to be worried about this is just a dumb sheep. We believe you, and we have evidence that you were right along, right here.” Fear is a powerful motivator, and you can make people believe and do some pretty extreme things if you just keep telling them “yes, that thing you’re afraid of is true, but also it’s way worse than you could have ever imagined.”

Real information is often complicated, hard to understand, and inherently unsatisfying. 

The information that comes from the scientific community is often very frustrating for a layperson; we want science to have hard-and-fast answers, but it doesn’t. The closest you get to a straight answer is often “it depends” or “we don’t know, but we think X might be likely”. Understanding the results of a scientific study with any confidence requires knowing about sampling practices, error types, effect sizes, confidence intervals and publishing biases. Even asking a simple question like “is X bad for my child” will usually get you a complicated, uncertain answer - in most cases, it really just depends. Not understanding complex topics makes people afraid - it makes it hard to trust that they’re being given the right information, and that they’re making the right choices. 

Conspiracy theories and misinformation, on the other hand, are often simple, and they are certain. Vaccines bad. Natural things good. 5G bad. Organic food good. The reason girls won’t date you isn’t a complex combination of your social skills, hygiene, appearance, projected values, personal circumstances, degree of extroversion, luck and life phase - girls won’t date you because feminism is bad, and if we got rid of feminism you’d have a girlfriend. The reason Donald Trump was an unpopular president wasn’t a complex combination of his public bigotry, lack of decorum, lack of qualifications, open incompetence, nepotism, corruption, loss of soft power, refusal to uphold the basic responsibilities of his position or his constant lying - they hated him because he was fighting a secret sex cult and they’re all in it. 

Instead of making you feel stupid because you’re overwhelmed with complex information, expert opinions and uncertain advice, conspiracy theories make you feel smart - smarter, in fact, than everyone who doesn’t believe in them. And that’s a powerful thing for people living in a credential-heavy world. 

Many conspiracy theories are unfalsifiable. 

It is very difficult to prove a negative. If I tell you, for instance, that there’s no such thing as a purple swan, it would be very difficult for me to actually prove that to you - I could spend the rest of my life photographing swans and looking for swans and talking to people who know a lot about swans, and yet the slim possibility would still exist that there was a purple swan out there somewhere that I just hadn’t found yet. That’s why, in most circumstances, the burden of proof lies with the person making the extraordinary claim - if you tell me that purple swans exist, we should continue to assume that they don’t until you actually produce a purple swan. 

Conspiracy theories, however, are built so that it’s nearly impossible to “prove” them wrong. Is there any proof that the world’s top-ranking politicians and celebrities are all in a giant child sex trafficking cult? No. But can you prove that they aren’t in a child sex-trafficking cult? No, not really. Even if I, again, spent the rest of my life investigating celebrities and following celebrities and talking to people who know celebrities, I still couldn’t definitely prove that this cult doesn’t exist - there’s always a chance that the specific celebrities I’ve investigated just aren’t in the cult (but other ones are!) or that they’re hiding evidence of the cult even better than we think. Lack of evidence for a conspiracy theory is always treated as more evidence for the theory - we can’t find anything because this goes even higher up than we think! They’re even more sophisticated at hiding this than we thought! People deeply entrenched in these theories don’t even realize that they are stuck in a circular loop where everything seems to prove their theory right - they just see a mountain of “evidence” for their side. 

Our brains are very attached to information that we “learned” by ourselves.

Learning accurate information is not a particularly interactive or exciting experience. An expert or reliable source just presents the information to you in its entirety, you read or watch the information, and that’s the end of it. You can look for more information or look for clarification of something, but it’s a one-way street - the information is just laid out for you, you take what you need, end of story. 

Conspiracy theories, on the other hand, almost never show their hand all at once. They drop little breadcrumbs of information that slowly lead you where they want you to go. This is why conspiracy theorists are forever telling you to “do your research” - they know that if they tell you everything at once, you won’t believe them. Instead, they want you to indoctrinate yourself slowly over time, by taking the little hints they give you and running off to find or invent evidence that matches that clue. If I tell you that celebrities often wear symbols that identify them as part of a cult and that you should “do your research” about it, you can absolutely find evidence that substantiates my claim - there are literally millions of photos of celebrities out there, and anyone who looks hard enough is guaranteed to find common shapes, poses and themes that might just mean something (they don’t - eyes and triangles are incredibly common design elements, and if I took enough pictures of you, I could also “prove” that you also clearly display symbols that signal you’re in the cult). 

The fact that you “found” the evidence on your own, however, makes it more meaningful to you. We trust ourselves, and we trust that the patterns we uncover by ourselves are true. It doesn’t feel like you’re being fed misinformation - it feels like you’ve discovered an important truth that “they” didn’t want you to find, and you’ll hang onto that for dear life. 

Older people have not learned to be media-literate in a digital world. 

Fifty years ago, not just anyone could access popular media. All of this stuff had a huge barrier to entry - if you wanted to be on TV or be in the papers or have a radio show, you had to be a professional affiliated with a major media brand. Consumers didn’t have easy access to niche communities or alternative information - your sources of information were basically your local paper, the nightly news, and your morning radio show, and they all more or less agreed on the same set of facts. For decades, if it looked official and it appeared in print, you could probably trust that it was true. 

Of course, we live in a very different world today - today, any asshole can accumulate an audience of millions, even if they have no credentials and nothing they say is actually true (like “The Food Babe”, a blogger with no credentials in medicine, nutrition, health sciences, biology or chemistry who peddles health misinformation to the 3 million people who visit her blog every month). It’s very tough for older people (and some younger people) to get their heads around the fact that it’s very easy to create an “official-looking” news source, and that they can’t necessarily trust everything they find on the internet. When you combine that with a tendency toward “clickbait headlines” that often misrepresent the information in the article, you have a generation struggling to determine who they can trust in a media landscape that doesn’t at all resemble the media landscape they once knew. 

These beliefs become a part of someone’s identity. 

A person doesn’t tell you that they believe in anti-vaxx information - they tell you that they ARE an anti-vaxxer. Likewise, people will tell you that they ARE a flat-earther, a birther, or a Gamergater. By design, these beliefs are not meant to be something you have a casual relationship with, like your opinion of pizza toppings or how much you trust local weather forecasts - they are meant to form a core part of your identity. 

And once something becomes a core part of your identity, trying to make you stop believing it becomes almost impossible. Once we’ve formed an initial impression of something, facts just don’t change our minds. If you identify as an antivaxxer and I present evidence that disproves your beliefs, in your mind, I’m not correcting inaccurate information - I am launching a very personal attack against a core part of who you are. In fact, the more evidence I present, the more you will burrow down into your antivaxx beliefs, more confident than ever that you are right. Admitting that you are wrong about something that is important to you is painful, and your brain would prefer to simply deflect conflicting information rather than subject you to that pain.

We can see this at work with something called the confirmation bias. Simply put, once we believe something, our brains hold on to all evidence that that belief is true, and ignore evidence that it’s false. If I show you 100 articles that disprove your pet theory and 3 articles that confirm it, you’ll cling to those 3 articles and forget about the rest. Even if I show you nothing but articles that disprove your theory, you’ll likely go through them and pick out any ambiguous or conflicting information as evidence for “your side”, even if the conclusion of the article shows that you are wrong - our brains simply care about feeling right more than they care about what is actually true.  

There is a strong community aspect to these theories. 

There is no one quite as supportive or as understanding as a conspiracy theorist - provided, of course, that you believe in the same conspiracy theories that they do. People who start looking into these conspiracy theories are told that they aren’t crazy, and that their fears are totally valid. They’re told that the people in their lives who doubted them were just brainwashed sheep, but that they’ve finally found a community of people who get where they’re coming from. Whenever they report back to the group with the “evidence” they’ve found or the new elaborations on the conspiracy theory that they’ve been thinking of (“what if it’s even worse than we thought??”), they are given praise for their valuable contributions. These conspiracy groups often become important parts of people’s social networks - they can spend hours every day talking with like-minded people from these communities and sharing their ideas. 

Of course, the flipside of this is that anyone who starts to doubt or move away from the conspiracy immediately loses that community and social support. People who have broken away from antivaxx and QAnon often say that the hardest part of leaving was losing the community and friendships they’d built - not necessarily giving up on the theory itself. Many people are rejected by their real-life friends and family once they start to get entrenched in conspiracy theories; the friendships they build online in the course of researching these theories often become the only social supports they have left, and losing those supports means having no one to turn to at all. This is by design - the threat of losing your community has kept people trapped in abusive religious sects and cults for as long as those things have existed. 

New day for dirigibles?

Steampunk fans rejoice! Starting in 2024, you’ll be able to survey London while sipping a cocktail in the cabin of a blimp, if this UK firm gets its way. Hybrid Air Vehicles (HAV) recently raised $2 million to commercialize its helium zeppelin, the Airlander 10. The hull is a laminated fabric supported by carbon fiber and fiberglass skeletons. Filled with helium, it’s just barely heavier than air overall. HAV says it expects to have zeppelins in commercial service starting in 2024, and test flights like the one shown are already underway. Pass me an angostura sour and a monocle.

Worried about the helium shortage? HAV says 600 of it’s blimps would need 1% of the world’s helium supply. But that shortage may not be happening anyway. Look for an episode of C&EN’s Speaking of Chemistry in October all about helium shortages and the scientific response to them.  — Craig Bettenhausen

Audio oxidation

The energy to get a chemical reaction going can come from a number of sources. Ilha Hwang and Rahul Dev Mukhopadhyay are exploring the use of a phat beat. Members of Kimoon Kim’s group at Korea’s Institute for Basic Science, they placed a dish containing a water (or aqueous) solution of reduced methyl viologen, which is blue, dissolved in water on an audio speaker. In the presence of air, the solution turns colorless as oxygen dissolves and oxidizes the methyl viologen. When the team played a 40 Hz tone, a deep booming bass note, the reaction proceeded faster in certain parts of the standing wave that the audio tone produced in water. The team hopes their research will open up new ways to control and visualize chemical reactions. This video is sped up to 80x normal speed. — Craig Bettenhausen

I don’t want to get political, but I really do not understand why people feel they need to use explosives to announce the gender of their baby.   It seems like every few weeks I see one of these stories where the whole thing goes terribly, terribly wrong.   

It occurred to me that a lot of the people who do this sort of thing are probably also terrified of various foods, cosmetics, and other household items for containing harmful chemicals.   But they’ll happily build an IED in the backyard to tell everyone how the last ultrasound turned out.

Why can’t people use those cakes where you cut them open and it’s pink or blue inside?   Even that sounds like way more trouble than it’s worth, but at least a cake isn’t going to kill somebody.   Unless it’s got fireworks in it, and I guess I can’t rule out that someone might have tried that.
