One of the first things I did after adding a Hayes 300 baud modem to my Apple ][+ back in 1981 (after dialing in to some local BBSs) was to compute fax images, and use the fax as a printer that would be much quieter than my noisy dot-matrix printer. But the lack of memory to hold an entire page at 200x100 DPI (approximately "Standard" fax resolution, ~200 kB/page) meant I couldn't simply plot lines and draw characters into a large bitmap. I had to get a bit more clever. My first thought was to have a representation of the plot and/or text I could then rasterize to a file on a floppy disk, but this rapidly became way too complex to implement quickly. I then noticed that the vast majority of fax dots were left white (not printed). When meant that an RLE (Run-Length Encoding) would be extremely effective. In RLE, you have a dot value followed by how many times it is used sequentially. I wrote a program (initially in UCSD Pascal) that would plot dots within a binary RLE representation of a fax page. Let's say an empty fax page is represented by "0[200,000]", which is simply 200,000 white (unset) dots. Now, let's say I want to plot a horizontal line that's 2 dots thick across the middle of the page. The resulting RLE expression would be: "0[99,300],1[400],0[99,300]". Even as text (binary is far more compact), that's a small representation of an entire fax page! The other advantage of RLE is it is ridiculously fast and easy to decode on the fly, far faster than reading uncompressed raw data from floppy, and fast enough to keep up with the fax mode of the modem. I added functions for drawing simple fonts, lines and conic sections (using Bresenham's algorithms) and went for it. Creating the representation was easy, but I had lots of trouble sending it as a fax. Documentation back then was fairly sparse, and I had to reverse-engineer the details of the Hayes fax commands. I soon learned that UCSD Pascal was poorly suited to real-time programming, and rewrote the fax send program in 6502 assembler. When I did this, I also wrote a program that would take my RLE fax files and send them to my dot-matrix printer (which was much cheaper to test with since fax thermal paper was expensive at the time). Of course, I soon learned I wasn't the first to attempt this, nor was I the best. By the time I finished my code, even Hayes had released a program and library that covered 80% of what I had done. All I did was port my code to draw conic sections and arcs. Later I added various spline functions. Then flood-fill of closed objects. Then I added dithering for filled areas. Then I switched to an MS-DOS PC and never touched the code again.
The most amazing thing about this story, aside of the fact that you did all this, is that you remember doing all this. I don’t remember what I ate for lunch.
I wish fax machines were as dead as he seems to think. I had to stay late at work last week because someone faxed us a 150 page document that took 90 min to print full of extremely confidential client information that I couldn't just leave on the machine for some random janitor to see. Except that the fax didn't completely go through. So they tried again. And again three more times the next morning. That was a fun day.
Matt was making a political joke. In the US election last year, Trump (who famously said "You're fired!" a lot on his TV show) made so many false statements during the campaign that some people said that Americans are living in a "post-facts world". Then, earlier this year, Trump's adviser Kellyanne Conway said the phrase "alternative facts" on live TV during an interview (prompting the response "alternative facts are not facts; they're falsehoods"). Matt was riffing on how similar "fax" and "facts" sound.
I love every second. It's easy to understand, well thought-out, and looks amazing. It's clearly one of the best Venn diagrams ever made. Oh, and the show was ok too.
The NHS is believed to be the biggest purchaser of fax machines in the world - I don't know how true this is because I can't bothered to fact check it. But what is true is that the NHS runs on fax machines, especially when it comes to communication between GPs and other parts of the NHS. I'm not terribly upset by this because it has a fair few advantages. 1) Because not many people have faxes it's really difficult to send confidential information to a random person by dialling the wrong number. 2) Actual signatures are transmitted, so if I want a GP to prescribe something for my patient, the fax, that I can put in the patient's notes means that it is a legal prescription. 3) You can't CC everyone in the NHS and bring the whole thing to a halt. 4) You get a nice receipt which means you are certain that your message has be received (whether it gets acted on is another thing...) So for something from the 1800's it's not a bad bit of kit. And a lot easier to use than the official NHS email system where it's all web-based.
A fax still cannot be accepted as a legal prescription, as it lacks the signature of the prescriber in indelible ink, especially for controlled drugs, but most pharmacies can dispense your medicine against a fax, usually on bank holidays when it's a genuine case of emergency.
Hi Matt! I have just come from your wonderful presentation at the Open in Norwich, where I secured your autograph. Everyone absolutely loved it- it was the best presentation so far in the event's history. Thanks again, JP.
There was, in the 80s, a product called "The Complete Communicator" which allowed a DOS computer to recieve a voice message and call you with the "Voice Mail" for 999 Voice Mail boxes. It could also send fax as a selection from a menu or receive a fax with a voice comment. You could even send a file, any kind, to another computer using "The Complete Computer" as a fax. This would be useful today as, if intercepted, the file is seen only as a black page. If this wasn't enough, you could pipe a call to another program, BBS Host, for the duration of the call; something I used. Then came Windows.
Man, you're a inspiration. I study Applyed Mathmatics in FGV, Rio de Janeiro, and here he have this talent show, the Fibonight (I know, the name is great). I thought "I can make people laugh like Matt Parker" And I told a lot of jokes there, in froint of my professors. The reactions was variable, but my professors liked, and some other students too! I told one or two jokes of yours in Portuguese, but most of all was selfmade.
Right after purchase i was brought to the page with download links. And then i also received 2 email messages, one with billing info and one with download links.
Haha! I was just checking if I missed you put the ties on and I thought to myself "must be a camera cut" or "that's why it cuts away"! Cheers for the explanation!
There's a surprising number of weird things that use faxes (at least in the U.S.), especially if you need to send someone a signed document. As a result, a scanner hooked up to an internet fax server is one of the more popular services offered by the public library where I work.
In 1966 fax technology used revolving drums that had to sync up on both ends. The sending unit would scan slowly across as the drum revolved under the scan head and the receiving unit would typically use a thermal paper to print on the drum. And, you could sit there and watch the spinning image appear (left to right if I recall correctly) as the bottom of the paper went flap, flap, flap...
2020 05 03 - No way - as of today this number is still valid... Added to my contacts so that I can "drunk fax" Matt Parker all the way from South Africa!
Fax machines are still used in the US, mostly for secure document transfer. The biggest users are the medical establishment and utilities like gas, water and electric. While they do transfer internal documents by intranet, and communicate with customers by email, many still require that signed forms be sent by fax instead of a PDF over email.
In 24/7 industries that can't switch off without catastrophe, there are lots of instances of outdated technology being used; I work in energy, we send and receive a whole lot of faxes. Someone recently joined the company I work for who was previously in shipping, where they also faxed a lot.
Here's a fun fact for those who have seen the faxes come through from the interval. When Matt says "OK, who faxed in binary? Who!?" in the recorded DVD footage, that was me, but the circumstances surrounding it are insane. When I sent that fax, I sent it from the middle of a university lecture, on the complete other side of the country. I *know* it's mine, because it decoded exactly to a portion of my message, and my signature is just legible enough on the page shown. As for the translation, it reads "How many primes does it take to change a lightbulb? 1, itself"
Mobile Phones had fax capability before apps, that is you could connect a mobile to a fax machine. The service option codes are 0x5 for a Group 3 Facsimile at 9.6kbps and 0xd for a Group 3 Facsimile at 14.4kbps. You would get a separate directory number for your mobile fax and then when it was called you were paged and served with that service option code. This was important because the voice coders used would filter out some of the frequencies needed and therefore needed to know it was a fax.
In US buy and use fax machines all the time as part of all-in-one printers (print, copy, scan, fax). Still use fax to place orders with broker - sign the form and fax it over. Fax lives! : )
Regarding the mobile fax machine, we were using the Lightweight Digital Facsimile model # AN/UXC-7 mounted in vehicles during Desert Storm 32+ years ago.
"I spent so much time thinking about whenever I COULD that I forgot to think about whenever I SHOULD" xD That line alone is already worth more likes than YT allows (hint: more than 1)
The only thing holding me back from going and getting some kind of program to send faxes to that machine is that this video was posted five years ago and I'm not sure if Matt is still paying for cell service for his mobile fax. Sending a fax that can't be received would just be pointless, right?
The mid-90s show _Loveline_ had fax machines on shelves above the studio set, so that any time someone faxed in a question, it would literally fall on the hosts.
Actually fax machines are still in regular use in specialized industries. Great for sending medical records around (in veterinary medicine many practices use paper records rather than electronic). Sending them via fax means no one has to scan, email, receive, print, mark as received, etc. just fax and it’s there.
I would *_love_* to see a video comprised of nothing but user submitted faxes flipping by... This bit reminded me of my first tech support job when I was in high school (early 90s), private corporate support. Big boss calls and asks *"How do I send a fax over the Internet?!?"* I asked if he meant an email *"What's email?!?"* he replies, and thus began a long afternoon. He'd been trying to send a fax from a spreadsheet he'd printed while he was dialed up to his ISP...
I like to think of myself as a scholar.. I seem to be spending more and more of my time researching maths and physics. But I find myself sick and unable to work. If I could afford it, and had the health, I would go to college and meet this guy.
I don't know about fax machines, but just a few days ago, I found that my cell phone could connect wirelessly to an unsecured printer in a random office in an office building. That could be what was actually depicted in BttF2, and we wouldn't have known the difference at the time.
It was very common in Spain for some companies to ask you to send a fax to i.e. end a phone line contract, assurance etc Seems that It's mostly dead by now but I won't be surprised to know that public administration and some companies use It to send invoices, POD's and things like that.
I remember before email took off, I heard of people preferentially faxing letters internationally. Faster than air mail, cheaper than verbally speaking on the phone.
I got this suggested after I had watched a video about the fact that the German Federal Constitutional Court only accepts letters and faxes but no e-mails.
3:37 Apparently no one realised this, so this is a picture of a tennis ball on fire, shot in the dark. Matt did this experiment to show that objects thrown near the surface of the earth follow parabolic trajectories. He has put and many other fantastic graphs in his amazing book 'Things to Make and Do in the Fourth Dimension '
I had no idea any of these were available online, I was always rather sad that these were only in the UK and I'd likely never see one. Now I have this one and Full Frontal.
Wow. Drunk faxing sounds like something I would do. Is your fax (omg there is a fax emoji 📠) still live? Or... Working... Or whatever the appropriate term for a fax that can receive faxes is?
"A genuine mobile fax machine!
No don't start now, it's not plugged in yet."
should have called it cellular
"Download a fax app" is definitely not a phrase I ever anticipated hearing
Matt Parker almost tricked me into believing that nobody owns fax machines... Then in 2019 I moved to Germany and oh boy, what a surprise.
Oh yes and mechanics and other shops were still using them to send and receive info into 2022
Even in the US many companies have/use them. Faxing a hotel at Disney is still the best way to get a room request :D
I have never laughed harder at a live performance regarding the life, death, and revival of the fax machine
I was amused, but didn't laugh at all. So... same!
It's just like vinyl records!
That seems to be quite a niche performance.
Off topic, but I love your profile pic!

9:23 you can't fool me, that VHS still has it's tab on. Aren't you worried about someone taping over it with some under par maths comedy show?
It's just a mock-up, not a real picture
I was impressed by the double tie and I re-winded the first time I saw it come out. Very well played.

Only two things are certain in life - death and faxes
I live in Canada and work in a Hospital where faxes are still used. It's still the best way to get a patient's chart summary from an other hospital.
hah, I rewound and watched it again to find where the ties went on just before the pause bit appeared.
Me too
Rewound - ha ha - did you watch on VHS? :)
Yes, I have all RUclips videos dubbed onto tape by my butler so that I can watch them on my CRT television. Doesn't everyone do that?
