I am always humbled when I see videos like this. Yesterdays news becomes history and history is always remembered professor.
Professor Roger Bowley. I salute you.
You have saved my life, two years ago I got an MRI of my spine and the doctors found the problem and it could be fixed.
I love you for this.
Damn, Roger, you should be proud. You've saved lives with nothing more than maths.
What a wonderful contribution, Professor.
Speaking as an accountant - You lot are one of the best things I have found on the whole of the Internet.
Thank you for pleasure and knowledge!
I've recently had to get an MRI scan of my brain, so I want to thank you for your involvement in improving and refining this technology.
Watching these videos never fail to inspire me to further my interest in physics and mathematics and the beauty of it all!
A big thanks to you Brady and to all of the professors :)
He is so awesome! It is a real beauty to see person who enjoys his work.
I almost cried listening to him, beautiful story, incredible man.
We are taught Bessel functions as undergrads in Italy. Well, at least, an introduction to the subject.
This guy. THIS GUY. I wish i could be as awesome as him...
Wow I never knew that - Im a long time periodic fan, and MrOldProf has always been my fav. Thankyou Prof Bowley - I scan on a big magnet and never knew I owe so much to you!!! Best Regards, J :)
That was a genuinely moving video. Cheers sir.
Its a shame how this one doesn't have that many views. It is by far my favorite TC video.
Well it really was a Green's function expansion in Cylindrical Coordinates that Bob Turner founding in Jackson's book on Electromagnetism. These involve K_m(r) and I_m(r) which are unusual Bessel funtions.
Wow prof Bowley! I already knew he was awesome, but this is beyond that!
Way to go Professor Roger Bowley. Way to go.
Oh that is so beautiful.
Brady, you should definitely put an SSD with all your youtube videos in the capsule!
Haha this guy! also, love the shirt Professor, you're a man of great taste.
Damn, I am solving a Bessel and Legendre series homework right now, started today and to be done with today. What are the chances? ( or might it just be the algorithm digging up my Wikipedia history)
We are studying Bessels functions in 4th semester of undergraduate course as a part of ''Mathematical methods for physicist''
yeah so weird.. we have bessel functions in 2 sem
Nice stuff. Kind of a downer-vision of the future though. Very sentimental/reverse-nostalgic.
"I just helped with the math for the MRI" He said it so nonchalantly , while my brain immediately conceived the thousands of people that device must have helped over time.
Very humbling :o.
lovin the time capsule
How efficient would be to make helium by bombarding alpha particles with electrons? Is it at least plausible or is it more of '10 trillion years to make one gram of it kind of thing'?
Not sure an SSD is the right way to store them in a time capsule, because digital formats can be replaced at any point during the time between sealing and opening the capsule. The best way would actually be to choose some of his best videos and store them on film (with the audio on magnetic tape), I believe. That way, there are fewer format barriers to cross for the people who will try to figure it out in a century or more.
so how much did he get of the patent income? like a couple of thousands or a 100.000 and more?
Street cred!!! No amount of money can top that though :D
I kind of almost teared up here.
Wow, so I (sort of) know a (part) inventor who is still living ! Awesome
I have an MRI every six months, and I certainly don't mind it, but next time I'll be more excited knowing this.
amazing video and an amazing story :)
We had Bessel functions in 2nd year of engineering and we need them in frequency modulation. I have a hard time remembering the series :-/
That. Is. Awesome.
People often talk of their two deaths - the last moment you take a breath, and the last moment someone utters your name. That means that you are going to be known for working on an invention that may not be surpassed until long after the helium reserves are long depleated.
Brady should put the footage in the time capsule
No Bessel functions for undergraduates? I believe first mention of them was my second year of University and every semester from there...
I am not speaking of erasable ROM, but write-once ROM such as a PROM, where the data is permanently stored through burning internal fuses, or mask ROM, where the data is fixed at the design phase (though on a small scale mask ROM is not cheap, unlike PROM).
Any kind of re-writable storage is likely to be subject to degradation due to chemical processes, quantum effects and high-energy events like cosmic ray impingement.
Made from aluminized mylar, factory-made CDs are actually quite durable.
May I just suggest having subtitles? :)
The automatic captions were terrible.
Go Roger!
MRIs don't even need helium after they're initially filled anymore. They can be filled once at the installation and sealed off with a cryogenic pulse tube helium liquefier at the top to recondense the helium that evaporates to create a zero-boil-off system. This is the standard now. There will always be enough helium for these small scale cryogenic uses.
Can we please get a link to Prof. Bowleys paper? I would very much like to read it.
A video abut what would happen when we finish our He supplies!
I wish I had millions --- instead I drive a ten-year old Toyota Corolla. Life is not fair, but so what? The invention got me promotion to the title of professor which is a big deal in the UK.
I did not save your life; your doctors did. Your comment made me feel good.
Flash memory is absolutely not permanent storage. It is very fragile and temporary, depending on electric charge trapped within a matrix. When the electric charge leaks away, the data is gone! More fool you if you archive important data in flash memory.
Well done Roger.. :-)
Roger's awesome
As long as there are people like this one left on the planet, humanity will always have be special. But the day they die out the world might as well be swallowed by the sun, humanity an anomaly of little note in the universe, leaving behind not but a small trace of entropy to mark its short and wretched blight on time.
As it says in the description, yes, it is.
You're amazing
Does your computer still have legacy tech? Parallel ports, serial ports and PS2 ports have all gone from most new PCs and they're not even 50 years old.
I was having trouble hearing him over the volume of his shirt
Why is the capsule always empty again?
Is this paper available in a digital format?
Seems like we keep putting things in this capsule, but it every time it's still empty
Thank you, you flatterer.
Yeah we had them too, in Mathematical Methods of Physics course.
Would like to know about quantum coherence please.
Great vid as always!
Anyway,I bet One Piece's fan will look the video at completely different perspective.
Even so, hardware could easily be built at any time using the specifications for the interface, which will be available to future researchers (barring a complete collapse of civilization).
Whether they actually bother will depend on how far in the future it is, which will determine the value of studying this content. Unfortunately the content of flash memory is likely to be lost after a certain number of years or decades.
The silicon may be durable, but the information stored is not. Even if carefully stored, a typical consumer flash drive can't be expected to be reliable over decades.
Most ROM chips are far more durable, and burning them can be done pretty cheaply. This would be a better option for long-term storage. Another option is optical discs such as factory-produced CDs (not CD-ROMs).
However, I suspect this "time capsule" is more of a PR gimmick than a serious attempt to store anything.
And we come full circle, returning to one of the earliest and most reliable forms of data storage: the actual tablet. And you don't need a laser or CNC machine. A hammer and chisel would do just as well!
If money is no object, a bar of platinum could be etched with a binary representation of the data. This would hold more and last longer, but somehow I prefer the idea of Professor Bowley dropping his own crudely-hewn lump of rock into the capsule. Get to work Professor. :)
I'm an undergrad and have been taught bessel functions.
Roger Bowley is cooler than helium and more awesome than *too many
I felt smart because they tought us about Bessel functions as undergraduates. I don't remember any of it.
Uhhh, no. You don't know what you're talking about. A modern MRI with a properly maintained two-stage Gifford McMahon cryogenic liquid helium refrigerator reduces the boil-off rate of the liquid to less than 5 milliliters per hour. This extends the time required between helium refills of the cryostat to a number of years LONGER THAN THE LIFE OF THE MAGNET. It's close enough to zero for any actual difference to be inconsequential.
Once you research the running out of helium part... it is really astonishingly non-subtle. There simply is a very limited supply, that we are clearly running out of, and no other earthly supply to replace it with.
I see no way to get significant quantities of helium (outside of scyfy tales of harvesting it in space, which won't realize before we run out).
Thanks, bet he's the envy of the theoretical physics dept at Nottingham! Lucky in a way, he published the paper in the 80's and never really had to do anything else since ...
So...basically, Roger is rollin' in dough. A small percent of a massive patent income is a massive amount of money! Good on you sir!
I wonder how much he gets Stickeroo, are we talking £100's maybe £1000's per year or what ?
a nice shirt, there
Do not despair. Even if we run out of helium, we will find a way to super cool things.
Way to go Professor :D 2:07
However hard you try, Helium leaks. "Zero-boil-off" is an engineering term, and over time the 'close enough is good enough is perfect'-stance of engineering will be trumped by the inevitability of leaky He.
Bloody keypad and "done" button, I meant to say he is more awesome than *too many variables, insert here* :P
Those elipsis dots to the side are precisely for that. You can edit your posts after uploadng :-)
Well, MRI machines cost hundreds of thousands of dollars, and they are used all over the world. I would go out on a limb and safely say he has made millions from his share of the patent. His patent is a fundamental part of the technology. He probably hasn't made tens of millions, but a few million I'm sure.
I was taught Bessel functions in Physics.
What kind of human downvote a comment like this one?
Exceptfor that in some time no one will know what USB, or PDF, is.
it starts to get dirty at 1:47 gets real dirty at 2:06
You know that you don't have to watch this, right?
Well, if all the Helium will be gone in 100 years time... there's another reason to go into space!
"Perfect" only exists in theory.
why should we run out of helium in 100 Years ?
omg what is this fake? The capsule is always empty when they put things in it. I am dissapointed :)
Not even close to in time. Even a best case scenario would see widespread nuclear fusion only post 2075.
Google "who invented the MRI" Raymond Vahan Damadian, thanks to all who give him no acknowledgement. -_-
Oww well done! (your 2nd bragging brit!) But prof ya gotta come to the USA to work on your use of "superlatives" ! :-)))
I got the first view! Hooray!
