- Terry Davis (author of TempleOS) demos his SimStructure physics simulator.
Here he makes a PID controller (en.wikipedia.org/wiki/PID_con...) based on math from the book "Numerical Recipes In C".
PID controllers are found everywhere today. They control rockets and even a simple espresso machine like the Lelit PL41TEM. - Věda a technologie

We are sorry, we let you down Terry.
It is our fault, we failed as humans to let such an amazing mind be lost.
Riyadh Elalami It’s no one’s fault schizophrenia/schizophreniform can happen to anyone.
@L P ?
F that, there's almost nothing that can be done to treat schizophrenia.
The man lived in God's way, according to him. No sorrow required.
No F pun intended, wow.

"Back in 2000 it was pretty impressive, but now they have grand theft auto and stuff."
I think this phrase is relevant in a sense not many people can understand.
Regarding the software, after Terry's demonstration it still impressive even today. It's so unfair such a brilliant mind be screwed by such a terrible disease.
Rest in peace, Terry.
GTA was released in 1997 and this garbage wasn't impressive in the year 2000, 2016 let alone in 2020.
@@Ficker2o hateful and envious of a mentally ill person. This work was absolutely impressive for someone who was diagnosed with and dealing with schizophrenia at the time he wrote it - before he wrote it even, since he was diagnosed in the 90s. I’d like to see you do anything even remotely as impressive while mentally ill and heavily medicated. You must be the guy that catfished him and convinced him to go off his meds, which directly led to his death.
@@Ficker2 can you do it?
@@Ficker2okay johan
Garbage hahahahaha this is a piece of software not even 0.01% of existinh software developers could write
Safe to say this man was on a totally different level of extremely smart.
The thing is, actually, this program is simple. Any person with some physics and programming knowledge COULD made that. But, many of these people WOULD NOT sit down and make something like this recreationally.
@@patrickthepure Ah the classic "I could do it, I just don't want to".
@@patrickthepure Yes anyone can make it, even a sub 100 IQ person can. The difference is the effectiveness and understanding Terry had. If you were actually smart you would know this and not come with such a pointless comment.
@@BungerOverheat Do you even understand what you read? That's exactly what I said. There are perhaps hundreds of thousands of people working on much more sophisticated projects similar to this. Are you even aware of the technological advances around you? This program is not a result of "totally different level of extremely smart". Such people are dozen a dime. What's special about Terry is his mindset.
@@elliott8596 Well, I personally do (in a level much more lower than Terry), but the people I know does not. They don't do anything technical outside their jobs.
It's actually a really brilliant introduction to control theory.
I've been trying to wrap my mind around actually programming a PID controller for a while. I've read, and watched many videos about control theory but none of them are specific to programming. I learned more from this video than I have in any other.

(╥_╥)
@@xd-os7jl lol I love Kerbal space program..
Also I don't understand this I don't know calculus
You don't know shit about control theory if you think this was a great introduction to it. It was not even an introduction to anything, it was some incoherent BS.
I like how people are saying this is simple and any engineering student can make this. This guy literally sat down in his chair and throughly explained everything in detail with no google or anything. His level of understanding is what makes him so brilliant especially back in the day.
Yep. People will always say that when someone explains anything thoroughly enough. I can't recall how many times in class I watched a professor do something insanely complicated and have them explain it well then think to myself "this is easy, I totally can do this," only to have it kick my ass later. 99% of the time when someone says that about something they've not done before, they are bullshitting themselves.
Any student can probably make a simple OS. But it's not gonna be anything to write home about. Temple OS is leagues above anything an average CS student can create after an OS programming course. People want to shit on Terry and diminish his achievements just because he was somewhat controversial.

I love how lucid and coherent he is here. His explanation is great. We miss a true genius. :(
@Xeno Phon this bank filling nonsense will never stop as long as capitalism still exists and continues to fucking ruin this planet. instead of caring about the wellbeing of us as a whole people only care about the fucking money in their pockets. and it's going to keep being that way since there is no salvation for this world.
@@crylune Ohh yeah can't wait to starve to death and go against human nature. Stop with your utopian ideas for dystopian assholes.
@Xeno Phon
"Stop all this star gazing"
Idiotic. The space exploration and discovery is extremely valuable; it is also very cheap. Also, did you know that humans can multitask? You don't have to dedicate our entire species to a single goal or project you know. A very large portion of environmental and recycling technologies come from what was created from space flight and travel. Which benefits our entire species.
"as a crazy person that did something no one else could do with an operating system."
This is false. He was smart, but his OS was not all that impressive. He was doing things that people learned how to do decades ago. The only reason it seems extremely impressive is because his schizophrenic mind led to an incomprehensible OS. This isn't genius, it's obfuscated.
@@LaFonteCheVi Yeah, the ol' "I can do it, I just can't be bothered" attitude.
I apologize for the shitty argument, but if it's so easy why doesn't everyone else just whip out a 64 bit OS single handily?
@@crylune reeeee! capitalism reeeeeee!
He made and OS with a compiler and assembler and now this UI with physics and PID controller and a command interpreter? Very impressive programmer. Much respect.
A lot of people like to downplay his achievements. It's not even about the fact that he accomplished some of the hardest and most time-consuming tasks to do in programming (making an operating system *and* programming language solo), he also did this while suffering from horrible mental illness. What a shame. I can only imagine what he could've done without the burden.
@@giannigiovful I suspect his mental condition may have helped his achievements, gave him the obsession to code for hours and hours which other people lack.
@@HarveyHirdHarmonics comes with price.
@Prince Otter2 very good message ,man.
I hope people learn from him and from learning about his story
@@HarveyHirdHarmonics Yes, I think he invested himself body and soul in his code to keep in touch with reality, he has to fight constantly against his mental hallucinations.
Whenever CZcams recommends me Terry Davis videos I always watch them in their entirety and end up depressed
Cheer up buddy. It will all be OK.

@vovcher Bro are u in rvvz’s server
It's because you see a pure soul, and we lost that guy.
This is a legitimate alternative to simulink. Especially simulink in the year 2000. This guy was a genius. I think like so many other geniuses before him, he will only be appreciated long after his death.
Terry Davis will never be remembered. He’s already gone and only a small sliver of humanity knows of his existence. He left behind nothing to call attention to his name but an OS that will only ever be looked at by a tiny, tiny fraction of people. I say this not to disparage him but because it’s true.
@@derekirish5121 I disagree, Terry built templeos and taught many of us about programming. We can carry on his legacy now. Kinda reminds me of Noah's ark in a way. He built it because god told him to. He didn't make or ask any of us to try it and we all went along for the ride. I know that's kinda of a far stretch. Btw I'm not a religious person just want to throw that out there. Sorry if my English is bad
@@derekirish5121 yeah but so what? everything will be long gone eventually. The fact that it exists in any moment and time is enough.
@@derekirish5121 Look at Vivaldi who was almost completely forgotten after his death, and is now regarded as one of the greatest composers of the baroque era. Look at Van Gogh. There are a lot of cases when people who were out of the ordinary and were not appreciated because it was not in the 'zeitgeist'. It took a change of generation (or 20 generations in Vivaldi's case) to appreciate their greatness. And in the internet nothing is ever truly gone.
For example, if there comes a time when computer programs can be regarded as a sort of art, Terry will be regarded as an avant-garde artist way ahead of his time, and perhaps a founder of a genre. It's not something that I can speculate on coherently because today there's nothing like a museum for well written programs (as an example).
@@Project1182 Yeah good shit, collapse on your own illogic.

Wow me too... this guy was incredible if NASA had hired him we would have arrived at Mars years ago 😂
he would but the nasa works has touches with the CIA wich is a red flag . Also nasa ain't catholic @@luisdespiau8704
Poor guy... Seems like he was really creative and super highly motivated to make things. That's what makes a programmer good.
SimStructure still better than GTA
GTA physics engine is HAVOK, a program like simstructure requires quite a lot of CPU usage for math calculations to be as realistic as possible, meanwhile GTA doesn't makes the same amount of calculations because cpu must do other things (logic, AI, rendering, etc) so to prevent all the workload beign heavily bottlenecked to the cpu the physics calculations may have be already pre calculated or just "nearly as accurate" physics, also take in mind PS4 and Xbox One consoles gen had a weaker cpu compared to Cell PS3 so from GTA IV to V the physics were downgraded thanks to that cpu generation being weaker.
@@doomslayer8985 PS4 isn't weaker than Cell.. Cell only has 1 normal CPU, PS4 has 8 full fleded CPUs while the extra CPUs on cell are only coprocessors. Most of the calculations for HAVOK could also be offloaded to the GPU, the reason GTA V physics are worse is developers are lazy.
Okay the fact that he wrote all of this from scratch as a hobby is just mind blowing
The more I see of Terry's work, the more I'm convinced he really was the smartest programmer that ever lived
He was but it's possible he is in a facility forced to develop software for the glow in the dark 😔
@@mrkitty777 pretty sure they have their own programmers.
@@Matt_10203 but they glow in the dark
@@Matt_10203 How do you think they got their programmers?
He's definitely one of those people who really throw themselves at whatever they're doing. His story is tragic, but everything he's achieved, even though ultimately not useful, is inspiring. He's a testament to how powerful passion and purpose are in a person's life. I've met some incredibly intelligent people that I imagine have 140-160+ IQ, but likely won't achieve anywhere near the amount Davis did, because they lacked the conviction Davis has kept alive for most his life.
It's saddening to see him go and know that outside of him programming his life was abysmal, but he found his reason to live. Nietzsche said that "He who has a why to live for can bear almost any how." and Davis is the most perfect evidence of that being true.
Just a measure of how smart this dude is: he made and tweaked a PD-controller in less than 3 minutes, something my teachers expect me to do in 3 weeks.
He's not smart. The rest of us are just stupid. Perspective ;)
You get 3 weeks, because your teachers know the US education system is garbage and that americans have "zero" attention span...
@@Microphunktv-jb3kj Or maybe because we're not American and we have 10 other deadlines to work on in the same 3 weeks and the fact that you don't even know what I'm even studying.
@@jojojorisjhjosef How does it take 3 weeks to implement 1 basic equation?
@@SpencerLemay You have to tweak it for it's specific system, in Mr. Davis' case, a rocket hopper, which can take some time depending on the system. And ofcourse it was my first time doing something like this so me and my classmate were learning as we went.
Maybe Terry died because TempleOS was seen as complete by God and God decided it was time for Terry to return to heaven.
Jc Dock Wow, that actually makes me feel a lot better, I don’t believe in god personally but imagining that’s true makes me so much happier. It means this great man didn’t die for nothing. Thanks for writing that comment.
@@BreakTheBeat852 no problem, I don't believe in God either but if he does exist I would like to think that Terry is with him
@@jcdock why do you assume it would be a "he"?
There is no god, only delusional humans.
@@fuanka1724 I only have one response to that is, fuck off. Don't inject your bullshit into a nice comment thread
@JK FRT who's to say god does or does not exist? It's like the last thursday theory in a way, any proof for god's existence can be labeled as fake, and any proof against god's existence can be labeled as fake too, neither side can be debunked all the way, so there's no way to know the truth for certain.
The chances that god exists are equal to the chances that god does not exist.
"Back in 2000 it was pretty impressive but now you have Grand Theft Auto and stuff"
He knew his control theory.
That could have a good pun.
yeah, I wonder where he learned about controllers... knew all the PID stuff from heart
@@moonasha He had an eletrical engineering degree, and a computer engineering degree too
@@robsonvonbrum1618 That makes perfect sense. Throughout his videos he indeed seemed a lot more well versed in physics than your average software developer would ever be.

not only when he was alive, they still do
0:50 Back in 2000 it was pretty impressive but now they have Grand Theft Auto and stuff
Justus Languell I believe this was actually created during the era of gta 5 as gta 5 was created back in 2013. Near the start of the video he opens CZcams to look at a hover test and there you can see a video that was uploaded 3 years ago, looking at it now reveals that it was created 6 years ago.
Meaning this was created somewhere around 2016 - 2017.
Unless I completely misunderstood your comment.

@@w1d3r75 All 3 honestly.
To think that I could not have learned control systems the way I did without MATLAB when there is someone that created their own MATLAB from scratch.. RIP Terry
Its a well known fact that he build his own compiler to create his own OS.... But I was not aware that he build his own Physics simulator that could be used to create his own Rocket simulator... This man was king... He was a genius.
This is still impressive even in 2019, especially considering all the circumstances in his personal life.
Terry's Mod, tmod for short.
xD
The more you learn about him, the more you pity him. It also makes me grateful for having a roof and a relatively normal brain.
Cool story bro
Vm Vr based
right??? the bar for being grateful goes lower each day haha.
jokes aside it is so sad just thinking what he could have become....
Divine intellect > relatively normal brain
@@ab8jeh I wouldn't be too sure there
This is one of the most competent tutorials I've ever seen.
He explains functions and variables, makes examples and states what every single line of code does.
Miss you so much Terry, hope God's treating you right up there...
I was extremely impressed when he started demonstrating the PD controller and the ship correcting its trajectory. Wow
3:42 the guy actually writes a PID controller, like it's as easy as making a coffee!!!
As an engineer, i can say just one thing:
WOW !
just wow!.
and to consider that everything was coded by a single person!!!
What people dont get is that the things terry did from scratch could be the skelleton basis of basically most modern pieces of software and for him to have done all that all those years ago alone and from scratch is just utterly impressive
Terry didnt fail us, we failed Terry, we lost something precious with him
Mind blown every time I see this amazing person do amazing things as if they’re just minuscule little tasks. Such a sad story. Rest In Peace.
That was an amazingly fast 20 minutes. If only the universities were filled with such passion.
This is still impressive to me. Of course we have 'GTA and stuff" today... but this software reminds me of a era of creativity in programming. This is gold.
We just watched terry make the code for a rocket launch and landing in 20 minutes. If his talents had been put towards science we could have put a man on mars in five years
i like how he mentions GTA and saying as if this isnt as impressive as before, but GTA had a company full to the brim of arguably the best game devs at their disposal but this dude is just ONE man.
He makes me feel like a dumbass, extremely humbling
most programmers cant even write two lines without pasting from stack exchange but this guy was something else
I know a bunch of programmers and none of them copy from stack.
A man with such deep understanding of concepts in multiple disciplines is truly a genius.
Terry was truly brilliant. So sad that we lost such an amazing person ☹️
Blessed are the cracked,for they shall let in the light
Do you know of the watchman's gaze?
Wtf i read this as blessed as the crackhead
I know people are memeing on him but as a programmer, it's honestly astounding that this guy has created all of this technology all on his own. Dude would've made an amazing entrepreneur if he wasn't schizophrenic.
Pretty amazing. He didnt just code TempleOS. It seems he was also a pretty good "normal" coder for existing OSes.
Very talented indeed, he also seems to have a great understanding about mathematics and basic physics.
Terry was a scientist and high profile T.I. people can be sure his code is now used by large corporations like Nasa
i always go back to this video every now and then, this guy will be missed
terry you were an amazing person and you will be deeply missed
Who thought him all these? He truly is a genius. I keep saying this and he still always amazes me. Rest In Peace, Terry.
He taught himself mostly. That's what makes Terry unreal to me. Despite his mental health issues he was an absolute genuine genius.
Litreally this is very impressive even today in 2021, I can say you are a pure genius. You are a legend
what a character... what a guy... brings tears in my eyes watching his vids nowadays...
This simulator is really good and you can learn feedback easily with this
I CANT BELIVE THIS. Absolute genius, pure genius...
I actually learned something from this. Thanks, Terry!
I've made a bunch of physics simulator many times in the past, also got curious about control theory at some point but still..
I am genuinely impressed by this. He really knows his stuff. Even more than the average programmer.
Very interesting video, this is great design, the command window is a great idea, allows the user to create simple physics based games, a lot of great ideas in there.
This is for seriously Nasa, not gaming 😲
That is actually some impressive stuff!
This man wrote this in the 2000s. Just let that sink in. Even today this is more than impressive.
I hope Terry's soul is at peace now. God bless this amazing man
If this man didn't have schizophrenia he legitimately could have been the greatest genius of our lifetime. I'm not even joking. People don't understand how insanely impressive coding a software like this alone in 1 year in the early 2000's is. There were full research teams trying to do this and failing and this guy did it in his spare time as a hobby while suffering from severe mental illness.
I got no doubt that he was actually the smartest programmer who ever lived.
it's actually insane how much charisma somebody can have. picture this same video with just any of person over the age of 45 who is just a normal guy teaching you about his setup, now put that in contrast to how animated (almost cartoonish) Davis is. it's just crazy to think about
There is a universe out there where this guy becomes a top computer science professor, no doubt in my fucking mind. The guy really was brilliant.
Did Terry seriously die? Oh man, I am a fan of his work! I'm an atheist but out of respect for his devotion I'll pray for him. God bless you, Terry.
Amen. Truly astonishing person.
Terry wanted you to Meet God sir. He is Real.

my man does not blink
Wish Terry did teaching in his career. His understanding and ability to break things down is astonishing. Fuck mental illness. RIP Terry glad you're finally free. Just wish it didn't have to end the way it did.
this was an inspiring thing to watch
It's insane to think that firstly he knew the control theory so well besides all his other skills and secondly writing this whole program in just one year? Are you serious? This could be something a team could work on for years especially in the 2000s.
His a God
And don’t forget, its not like this was the only thing he worked on in one year. He worked on many projects at once, this is just one project on a large pile of stuff.
This guy could have gone down in history cuz of his absolute genius
PID control explained brilliantly
This is awesome!
I would have loved to have Terry as a professor.
Terry is one of the great prodigies of our age that nobody's ever heard of

I come back to this video sometimes.
Terry A Davis is the reason i learned to code. he is the sole reason .
this is a program he single handedly written in 2000. in 2000 when i had my windows 95 computer and i was 4 and played Tunneler and Dyna Blaster with my friends, if we had this program it would legit blow out our minds.
We are so sorry Terry. You were undoubtedly one of the smartest programmers that ever lived, and we pushed you aside and outcasted your talent....
Gosh i wish he was more recognized for his intelligence. Such an important mind.
Amazing stuff. R.I.P. Terry A. Davis
man, if i have money i would give the whole world to him, what a genius.
such a nice way of teaching/working, make a system that works, break it on purpose, fix it, repeat
