Bone Shadows - Objectivity 76

[@realspacemodels]

This is the first x-ray-ted Objectivity episode!

[@ObjectivityVideos]

Great pun. Keith would be proud.

[@justcallmedan301]

Modern day radiographer here, checking in and very glad a hand x-ray nowadays takes 0.2sec instead of 4 minutes!

[@julessmith2]

Keith really is the man. I could listen to him talk for hours. What an absolutely amazing human being.

[@naota3k]

This is my favorite Objectivity episode. I just love the term "bone shadows." It's so reduced, so lovely.

[@superj1e2z6]

Gentlemen1: This could revolutionize the way we live! Gentlemen2: What shall we do to this technology then? Gentlemen1: Get me a frog.

[@ragnkja]

Frogs were quite common test subjects for this type of new technology, it seems. Perhaps the fact that most people who would have any way of interpreting the results would already be somewhat familiar with the anatomy of frogs helped?

[@gabewrsewell]

Not a frog... THE frog.

[@comsubpac]

Gabe Sewell the royal frog

[@helenaren]

I mean, remember what Van Leeuwenhoek did after he invented the microscope?

[@johnchancey3941]

Frog is giving the "okay" sign. He was fine with getting the x-ray done.

[@koszuta]

Surely it was dead

[@ArnimSommer]

Schrödingers frog?

[@davetremaine9763]

That frog was the the great-great-great-great-great-great-great-great-great-great grandfather of Pepe the frog. If only he knew his descendant would become a racist movement leader, would he still have donated his life to science?

[@bullsquid42]

In German we call x-rays "Röntgenstrahlen" (Röntgen Rays). But only now realised the reason for the different words is probably that his name is so damn hard to pronounce for English speakers ^^ But I still don't know what the x stands for

[@IsYitzach]

If Wikipedia is to be believed, Rontgen called it x-radiation for an unknown radiation. Basically, x is place holder that never got replaced.

[@Kaneanite]

Wilhelm Rontgen named the radiation he discovered X-radiation to signify it as an unknown type, over time it was shortened to X-ray and the name just stuck.

[@dirfgiS]

Yeah, I heard this story too. It seems likely, many scientists did that with for example planets and animals.

[@whoeveriam0iam14222]

if it was called Röntgen-rays in English people would know how to pronounce that

[@FirefoxisredExplorerisblueGoog]

Do you guys in Germany pronounce "Röntgen" with a hard "g" like "guten tag" or with a soft "ch" sound like "nacht"?

[@zacharyjakob]

I love Keith so much!!

[@randyhavard6084]

I really enjoy all Brady's channels, but this is my favorite and I'm surprised more people aren't watching these videos. They are probably like me, watching the periodic table of videos for years and not even realizing this channel exists.

[@JamyRyals]

What a wonderful channel full of priceless treasures. Keith of course is chief among them!

[@sooooooooDark]

i find going to museums and things like that very boring but love these videos

[@chai__tea]

It's true, these videos do a great educational work. I love going to museums, but I can also put myself into your shoes, because the way things are presented in museums can often be improved, I think. Whenever you go to a museum, try to find someone, who knows a little more about the exhibits than you do. A friend who's been there before or the one who recommended it to you. I find it so inspiring to have somebody point out the really outstanding exhibits or tell me little extra stories they know, because that goes a long way... compared to just reading the signs one by one. No one ever comes close to Keith, tho! ;-)

[@tncorgi92]

Well, that's decided then. Next time I head to the airport, I'm taking a suitcase full of frogs.

[@comsubpac]

Paul Drake don't try Australia then

[@otakuribo]

Brady: "Sir Joseph Lister. Most famous for..." me: "Listerine." Keith: "Antiseptic surgery." me: "... near enough!"

[@otakuribo]

Brady: "Aw yeah, Listerine!" Keith: "Mm-hmm." me: "Oh! So that WAS the guy." *feeling smarter than I actually am

[@pramitbanerjee]

xD

[@patricksanders858]

100 YEARS! 1 CENTURY from x-rays to the internet! Mind boggling!

[@joshinils]

3:00 bradys last pronounciation is the closest

[@Diablo_rdk]

The "unknown" object looks to me like it could possibly be a pipe cleaning brush. (for cleaning out tar residue from the tube inside the pipe) My father used to have one just like it. (or rather of a similar shape)

[@PTNLemay]

I love how Brady refuses to give up on this channel. The views may not be growing, but he's not going to stop posting new vids!

[@dielaughing73]

Would you stop taking advantage of private access to the RS archives?

[@Breakfast221]

It's really cool to see eras of nascent technology when people just experiment with anything they can get their hands on. A coin purse? Sure, throw it under the x-ray!

[@smaakjeks]

I literally went "ooooh" and "ahhhh" watching this

[@Nilguiri]

5:10 David Cameron would not have just stuck his hand in there.

[@Breakfast221]

Are you ever going to do a video about how this channel came to exist? Always been curious how you came to have a close working relationship with Keith.

[@Breakfast221]

Victor Dalloz Yeah, I assumed it had something to do with Sir Martyn, but I am wondering how "Hi, I'm Brady, I film videos with the Professor" went to "Let's make a KZbin channel with regularly uploaded videos, Keith and James."

[@ragnkja]

The first video Brady did at the Royal Society were with Sir Martyn in the library of the RS. I think Keith makes an appearance in at least one or two of them (he definitely appears in a later, but still pre-Objectivity video), so filming in the RS with Professor Poliakoff, as his title was at the time, seems to have been the most likely way for our two stars to have met.

[@PTNLemay]

He and Grey talked about it on the Hello Internet podcast. I forget which episode though.

[@dielaughing73]

​@@ragnkjayes, the Professor introduced them and I think the next step comes very naturally to Brady - "let's make a video"

[@erlandodk]

In Danish we still go to get a "røntgen-billede" (röntgen-picture) taken.

[@ulriksteenandersen4215]

Ahh jeg kan se du også er dansker.

[@PinkChucky15]

So cool to see those early xrays :-)

[@rileyleal]

5:32 that's kek, look at his hand! :O

[@andrewthecelt3794]

Roentgen discovered X-rays on my birthday, November 8 :)

[@kendokaaa]

Keith has very smooth hands

[@PopeLando]

Er... I knew who Joseph Lister was and what he did. But I'd never made the connection with Listerine before!

[@lgab]

4 minute exposure! That can't be good.

[@smaakjeks]

It was 1896. In those days they were using asbestos for napkins, and stored food in lead cans. Basically everything they ate, applied topically or breathed was not good.

[@Pile_of_carbon]

It's almost a miracle in itself that anyone survived the last 300 years. Adding to your list: drinking irradiated water and "curing" disease by drinking mercury.

[@Muonium1]

It probably wasn't THAT bad. At the time these images were taken apparatus was very rudimentary, the Coolidge tube hadn't been invented yet, they only had very VERY inefficient Crookes tube to generate X-rays. The very long exposure times were necessitated by the very weak source of x-rays they had to work with.

[@666Tomato666]

+10mintwo: on the other hand, they had insensitive photographic dyes, so it probably was more radiation than your typical dental x-ray now....

[@asdfghjkl9346]

Brady is very smooth while not knowing who sir Joseph Lister was :D

[@_rlb]

"Before the aeroplane took off". Was that one of Keith's puns?

[@ferraneb]

1:52 Brady, your gloves disappeared!

[@TheMaplestrip]

X-rays are called "Röngen rays" ("Röngen straling") in Dutch.

[@Jerome...]

0:22 Gus!? 1:52 gloves disappearance.

[@johnallardyce4164]

1:28 Quick, see if Keith is in the photo ;)

[@Taraalcar]

:21 Gus Fring?

[@Brotbart]

You did pronounce Roentgen correctly, Brady (that is with the hard g).

[@maru7768]

Keith you shoud apply to the position of maester of King's Landing, now that there's a vacation...

[@johnallardyce4164]

Obviously, you have not seen end of season six (Game of Thrones).

[@austinlindsay]

If Brady is in front of the camera, is Martin the one filming? Lol

[@Sliceofpi]

"Lister of course most famously known for..." Am I the only one that immediately thought "being the last surviving human on bored the mining vestl Red Dwarf." ?

[@tgvv2980]

Sliceofpi yes

[@ClockworkAvatar]

I was so sure this is where he was going.

[@liquidmasl]

in germany x-ray is callen röntgen. didnt knew that was the guy lol

[@joshfratis2738]

Here come dat boi

[@sashimanu]

PSA: please don’t post online the radiographs of your keys (unless you plan to change the locks in the near future). A random nemesis stalker of yours can very well replicate a key from an image, whether made in visual or X-rays.

[@ThomasPerkov]

we need a Keiths story corner...

[@thomilo44]

I can't be the only one who finds Keith's voice soothing right?

[@anthonyflanders1347]

T44 nope

[@jakefearing6640]

What a gangster ass librarian

[@alexandervonzoller-sakharo6386]

5 minutes exposure with Hard Roentgen radiation with no shielding and a probably large amount of backscatter from a prototype X-ray kenotron valve, also unshielded and probably unfocused, powered by a small megavolt tesla/oudin magnifying oscillation transmitter coil or at the very least an induction coil of about 500KV. The output in either REM, RAD, Sievert or Roentgen would be enough exposure to cause cellular damage and possibly be carcinogenic. Poor Lord Salisbury.

[@s3cr3tpassword]

What's in the box???? WHATS IN THE BOX?!?!?!?

[@mastrammasti5201]

hey Brandy plz do a video on messier. Charles messier

[@alexpalmer7704]

W.G Armstrong as in the Baron Armstrong?

[@Tevildo]

Alex - Yes, as in "& Whitworth".

[@Locut0s]

Given what we now know about radiation and what they knew nothing about... I would not want to have been one of those first few X-Ray subjects lol.

[@Yupppi]

A bit concerning that the most important people of England at the time were radiated like this!

[@ollythebest94]

Conversazioni is an Italian word

[@michielhoeree7604]

0:52 am i the only person who finds that sound genualy scary?

[@chillsahoy2640]

In the coming general election, don't vote based on policy. Vote based on which Prime Minister you think would be willing to have his (or her!) hand used for an X-ray and displayed at the Royal Society.

[@pramitbanerjee]

wait, people vote based on policy? i thought this election cycle was all about emotions.

[@rhemorigher]

Bloody frog smugglers.

[@djenter2]

In Poland we call them Rentgen's pictures not X rays ind is pronounced Rent Guan

[@U014B]

This is a reminder that there is a skeleton living inside you _right now._

[@Terrahex1]

sciencing science

[@garrysekelli6776]

Lol. At 5:50 Brady acts completely oblivious when viewing the lock picking Tools.

[@spinal_capped]

1:02 SAUSAGE PARTY!!!

[@PhilBoswell]

So was that the last time we had a Prime Minister who was an FRS? :-(

[@masteroftheart5548]

No Thatcher was an FRS (she had a PHD in chemistry if memory serves me right) but her divisive nature means no PM was elected an FRS since. It was quite common before her.

[@doublea9747]

His hair tho

[@lionkor98]

The guy with the xrays; Roentgen or Röntgen. Don't try to pronounce that, german sucks. But in germany we call X-Rays "Röntgen Strahlen", quite literally "Roentgen Rays".

[@boelwerkr]

And now all the non German say "Röntgenstrahlenröhre" :-)

[@Shibbymatt]

The rarest Pepe

[@andrewknorpp9716]

and a frog

[@phampton6781]

1:14 "You get all sorts these days". Standards have slipped then?

[@pramitbanerjee]

okay i am surprised that there is so little pseudo scientific work in those records

[@Janustus79]

So it's not only Professor Poliakoff who has problems with the name "Röntgen"? ;-) It's not that hard. Pronounce it as two words: "Roent-gen". "Gen" with a hard "g" like in "Generation".

[@chai__tea]

Actually, it's with a 'g' as in 'good'! May I suggest another English vocalization: Rurnt - gann (the 'u' sounds as if an 'r' would follow. But don't pronounce the second 'r', I just put it there for the sound of the 'u'.

[@LanceBeckman]

first dislike, jk
