I was sure the wheel was rigged... and, they probably could has saved a ton of time if they had rigged it. The participants spin the wheel clockwise, but Matt spins it counter. 🤔🤔🤔 And, once, even claims, "it does land on other colors".
The 3 cogs logo is a surprisingly common mistake. It happened at my work - a multi-national engineering firm. Upper management proudly emailed their new logo to tens of thousands of engineers, hilarity and red faces followed.
@@rhabenic in a drafting course that was required of civil engineering students, one day we were shown a video of a guy demonstrating how to go about sketching a threaded rod. He was doing a great job until he noticed that the threads on the model went the other way than in his sketch. I immediately laughed out loud as I knew what he was going to do correct the discrepancy. But when he turned the model end for end i was very disappointed to not hear anyone else laughing. I guess the guy thought that screws did not become left or right handed until they were given a head.
And, in the case of the gear train on the coin, it’s more complicated than just having an even number of cogs. The gear ratios have to be correct so that it runs smoothly without locking up.

Just went through the comments and I'm kinda shocked to see how little people appreciated this lecture. This guy is absolutely phenomenal. I was smiling throughout and learning some really cool stuff at the same time. He did an amazing job and I hope to see more from him on Ri. Huge fan, Matt!
There are thousands of comments and certainly you didn't read all of them? Even if you did what about all the people who watched but didn't comment(millions) which you can't know their level of appreciation. Maybe you appreciated it but you certainly didn't learn anything about ignoring data did you?

Ignore teachers. Their teachers lied o them too. And the teacher then lied to his students.None of these quantum theorists have thought an original thought or questioned their fanaticism. And dogmatic religious fanaticism always holds back the pursuit of knowledge. As did the quantum forefathers... the religious fanatics running europe in the Renaissance. They stopped copernicus and Galileo from publishing. As with modern quantum clerics...The truth was too much to take.
Teacher here. When that happens to me, I sometimes like to go: Is there anyone who....[all hands in the air].... Peed their pants? :D humor is easy with kids, I love it.
Here's one for the book. I learned in a highway design course that early on, they studied accident statistics and determined that, since accidents were more likely when driving on a curve or over a hill, that they could reduce the number of dangerous stretches of road by combining curves and hills whenever possible. This worked perfectly in achieving that result; of course that made the road even more dangerous.
@@sMASHsound our prof didn't say, but I think accident statistics might have had a hand in it. Either that and/or someone realized the logical error and explained it. Note that the people who made the invalid deduction might or might not have changed their minds. It is not as if there is a single cabal of engineers who make decisions about design methodology, and are the ones responsible for correcting their mistakes.
The glitch in the matrix started when the 'guest' spinner was supposed to call out the category, but then Matt did for the teen and adult. A good use of a Good Hour! Keep up the great content!
In the crescent moon misrepresentation, Matt correctly points out that stars shouldn’t be drawn inside the moon’s circumference. What is more troubling (to me) is that the tips of the horns have to be antipodal, I.e. 180 degrees apart.
Clearly, you don't run in truly geek circles! LOL (I don't either - now - but I was in an accelerated class with three super geniuses starting in fourth grade through 12th grade. Such a sentence would not have been at all unusual in that class!)
Yes it does. Not my choice when to start it - I think the fact they had 3 super geniuses meant they needed to up their game fast. Please note I was NOT one of the three!
You can simulate the same phenomenon in a bathtub full of water. If you shove your hands back and forth randomly, no meaningful waves will form. Only if you hit the resonance frequency of the tub (that is dependant on the size and shape of the tub) will a big wave form. For normal sized tubs that means pushing way slower than your intuition tells you.
Great show from Matt as usual! And Happy Birthday RI! The cogs thing reminds me of when my wife showed me her team's illustration of a marketing process with interlocking cogs: "that won't work!" I said. She was unconvinced it would matter, but did go back with my fixes. The next customer she spoke to confirmed that they were all engineers and, yes, it would have been a major barrier to credibility if they'd carried on with it as it was. I don't think I got any brownie points: she just realised that 'nerd' is a wider-spread condition than she'd thought.

You know, when it landed on probability the first time, I figured that Matt had rigged it to land on probability all three times. I did not expect him to have people spin it until it got green all three times, I figured these talks had a time time schedule and at 1:07 it had probably already spilled over by a bit. Bravo.

@@katherinekellmeyer5428 Hi and Hello. I gather people for a good cause: I wanna provide people with Links leading to bad or toxic people. Mobber, Racists, Sexists, Bullies, more. I got the Links and i need help with reporting them. RUclips is in a bad state and i think you heard of that. Many complain about it, its strike-system and its CEO: Susan. But... I mean... complaining about the State of the world is nice and dandy, but... how about acting? Doing something? So i made a Wiki where i store Links for all to use. You can at least pre-emptive 'block user' regarding the Racists and all those, but you can also do one thing more and report them, so YT becomes a better place. Interested?
You raise an interesting point, except that he probably could have better explained. This is a skewed distribution, so in this case the average is in fact better than 50% of the books.
Actually, median, mean and mode can all be called average, which is where a lot of misleading statistics comes from. I read this in Darell Huff's excellent book "How to Lie with Statistics".
I used the median recently in a report and to avoid the confusion of talking about the 'average' value, and knowing that the audience would not have heard of the median, I referred to the result as the 'typical' value i.e. the typical number of days worked, rather than the average number of days worked.
I've been very pedantic regarding the "stars where the moon should be" for years now, the difference between me and Matt is that he makes people laugh about it and I make people want to throw things at my face.
I just recently started realising what Matt meant when he said that math is about "getting it wrong and working towards the right answer". That is exactly what my current course in Applied Mathematics is like - that course is about a bunch of super-complicated equations that simply cannot be solved exactly, and instead require a lot of trial and error with various approximation techniques.
I'm really sad more people didn't get the joke, but I can't honestly expect people in the UK to know the nicknames of the states when I don't even fully understand exactly what countries and regions "the UK" even is.
@ K W I know what you mean, but the logic of what you actually said doesn't work. If you never thought that "X is my favourite mathematician" was something you'd say about a mathematician, then that suggests you thought you'd say it about a non-mathmatician, which obviously is then a paradox.
@@MrDannyDetail I don't think never thinking to say "X is my favourite mathematician" about mathematicians implies that they would have thought it of non-mathematicians either. It definitely makes it ·strange· to specify mathematicians, but that doesn't necessitate that they would have thought about it at all. "I would have never thought I would have a favourite member of set A that was in set A" is logically equivalent to "I would have never thought I would have a favourite member of set A", since any favourite one could have from set A must also ·be· in set A. I think this is more of a linguistic question of what including that redundant detail implies of the speaker, rather than a question of logic. When it comes to language, including unnecessary details like that imply that there exists a possibility that something could've been otherwise, or at least that the speaker thinks so. "I picked up a stone, and it was a stone" is completely true and logically valid, but the fact that the second clause is in there makes it sound like it the speaker is surprised that the stone was a stone, which is an illogical thing to be surprised by.
@@liebert234 Great response! As you say it's a linguistic amibiguity that depends on whether you consider the 'about a mathematician' part to be unnecessary repetition of the same fact, or a new piece of information that's critical to the intended meaning, which in turn depends on how the person says it. Perhaps I misspoke when using the word 'logic', but I'm not sure what other word could be used in it's place. I mean the deduction that the repetition would not be there unless it conveyed the possibility that something could have been otherwise, is itself a form of logic. I guess it only fails to be true logic because it would be an assumption rather than a hard fact.
Hats off to you, Matt! Loved it, esp. the ending -- @ 1:07:14 "...and I'm like, yeah, people have to earn the book"......yes, Matt, I'll do that.....thank you for this superb video!
To speak to the probability stories in this video: My wife is originally from Utah, and her dad grew up in American Fork. After we moved to the Portland, Oregon area, we were in a mall where we overheard a woman talking to a store clerk about her upcoming voyage to Utah. We had just moved to Oregon (literally a few months before), and we interjected ourselves into the conversation saying that we had just moved from Utah and was curious as to where she was going. She mentioned where she was going, but she also happened to mention that she lived in American Fork for a while. My wife said, "That's where my dad's from!" She asked his name, and when my wife told her his name, she exclaimed, "I dated your dad in junior high school!" We were BLOWN AWAY. Right then, my wife called her dad, and they talked for about twenty minutes on the phone in the most impromptu lovers' reunion I had ever experienced. It still brings a smile to my face.
Mmm... it's no longer something that happens to somebody in the world, but now we need to take into account it happening to a viewer of Mats video. That is a much lower chance.
@@renedekker9806 You have to increase the probability by a factor of how many strange coincidences you allow, as well as distance from the teller of the story. Matt's specific examples revolved around pictures shown to those about to get married. Now we're up to meeting someone who had a passing relationship with n degrees of separation. Each of these makes things exponentially more probable.
Last summer a young lady I had never met had her small puppy named "Stevie Nix" chase my young kitten named "Little Richard" up a tree. Strange coincidence? Sure, but that's not the real strange coincidence. After finally retrieving poor Little Richard, we got to talking and discovered that we had both gone to the same high school - 4500 km away. Albeit 40 years apart That was a day to play the lottery.
@@MrSJPowell Not to mention that we have to factor in what constitutes a "weird occurence". If there are no rules set up before hand, literally anything goes. While it is unlikely that one specifik freak occurrence happens to one person, and it is likely that it will happen to someone at least once, it is also,. by the same logic and reasoning, impossible to go through life without experiencing at least one weird event as an individual. You just need to look for the patterns.
Small number of people in the same location. And its easy. Only 300+million outta a few billion so what are the odds? Remember most Americans never leave the States. East coast to West coast its not even the entire continent.
I honestly thought the wheel was rigged, as the audience were turning it clockwise and matt was spinning it anti-clockwise and there was some mechanism that only worked in one direction.
more pertinently what are the odds of a complex clockwise/anti-clockwise fixing mechanism versus matt just re spinning till he get's green and editing the video But to answer your question, it's 1 in 5, or for 3 probability in a row I believe it's 1 in 125 (1 in 5^3)
i thought the same thing. and after he said the "dont believe everything you see on the internet" thing, i thought "but what if the video ISNT edited?"
45:15 Another fact that has to be considered is that the projections that the maps used to pinpoint the locations could also affect the shape. The previous researcher could have even selected the same locations on a different kind of a projection and identified another pattern. They're just random conincidents.
I was in an 80 story building during construction that during a strong wind storm that started twisting ( not just swaying) like crazy. It was quite scary. This was before the mass damper tank was constructed on top which I’m sure was where all the maths came in 😊
I worked in a brand new office building in Florida, someone didn't do their maths right because the first time we had a big wind storm the building bent and twisted enough to make some of the windows pop out of their frames. Anyone who parked in the lot adjacent to the building (think: upper management) had huge sheets of glass falling on their cars.
I wonder how many RUclips videos I'm in? It's actually scary to think there has almost certainly been a time, where someone online looked at me in the background of someone else's video (from a local vlogger or filmmaker for example). It's not scary that someone has seen me, what's scary is that I'm still there right now, and there are many short moments of my life literally sitting in servers all over the world, accessible to almost anyone.
I used to be a C++ software engineer. Before that I was an Ada software engineer. The Ada language has built in checks, one of which is a constraint error. If you get a constraint error, which is propagated out of the program - which goes up wires, which means different things to different bits, which... bang. I had the ESA crash report for Arian 501 pinned to my cubicle wall for decades :)
Matt, I'm from Texas and it's obvious that star is where it is from gravitational lensing. On an unrelated note, I'm not sure how to convey in text when my voice clearly indicates I'm grasping at straws.
I love the idea of maths being a progression in which you get less and less wrong. At school I got a lot wrong. Five years later I met my old maths teacher and he asked me what I was doing now. I was able to tell him that I was teaching maths!
When wheel landed on purple the 2nd time i suspected it was rigged but I underestimated Matt. He actually went out of his way to involve the audience and editors to fool us viewers! Love it!
South Korea, buildings, exercising Paul Shepherd and Jenga! (relates to the bridge feedback chapter). There is a Korean show on netflix called "my Mister" where the lead plays a civil engineer who designs buildings, and it mentions a building he designed where a gym caused problems and the damping mechanism he put in to counter it.
Mildly interesting probability story. I once visited Tokyo and during a wild night out lost my mobile phone. The next day my friend received a phonecall to come and pick up my phone. Turns out, it had been picked up by someone I had gone to primary school with 15 years prior who had recognised me in the photos on my phone, had contacted back to our mutual home country to get all the relevant phone numbers and then called through to arrange a meeting spot. The chances are pretty small and I am eternally thankful they went to the effort.

Of the 300+ video's I've watched on math and science, Matt Parker is my absolute favorite presenter. I am surprised, however, that a man of his obvious brilliant intellect would to ask, "Can everyone hear me OK?" as if anyone who couldn't hear him could possibly answer a question they haven't been able to hear!?!?! That sounds a bit like asking the audience, "Please raise your hand if you were unable to be here tonight"? LOL!
This makes me realize how easy it is to mess something up. Like imagine writing an entire movie franchise without having these kind of mistakes would be so hard.
The Parker square needs no justification. Except that it does. That is an inherent property of a Parker square. That is THE inherent property of a Parker square.
When it fell on "probability" the second time I joked to myself, "what's the probability of that!?". When it happened the third time I thought, surely it's rigged, but then I remembered you spinning it at the beginning and then you spun it again. Once you revealed the truth, it put my mind at ease, "oh thank God, it's just someone on the internet lying to me.".
The moment the second probability came up in the vid my suspicion was that it was rigged....and it was...just not when I thought it was and how I thought it would have been.

This is perhaps one of the hardest things to teach: that it's okay to make mistakes. The first solution you come to doesn't matter. What does matter is how you came to that solution, and what you do to make subsequent solutions better.

I have 4 probability events similar to the young couple who were strangers in the same photograph as children: 1. My sister was visiting Hawaii with a girlfriend and while there, unexpectedly met the husband of another friend. She recognized him. Turns out that she had met him 40 years earlier at his house when we were all children. We were at their house to encounter buggy driving with Shettland ponies. I was 8. Why she remembered the boy and this event was because of her keen interest in the beautiful drawing of a male African lion's head on the wall of this boy's bedroom (which he had drawn). She was a budding artist at the time. Fast forward up to her trip to Hawaii and recognizing him although he was thoroughly stumped who this woman was who was describing his childhood home to great detail back in California 1966. 2. My niece was getting married in Washington state into a family of preachers. The the family tree branch this young man was on was lateral to the one that I and my siblings were familiar with, but with the same sir name and same grandmother. At the family dinner prior to the wedding day, I was seated at the patriarchal table next to the matriarch of the family, herself. We strike up conversation and she asks me where I live. (central California) She says, "Is that a fact", well do you know my dear friend Victor D.?" I reply, astonished, "why, yes I know him, in fact we play music at church together almost every week!!... How do you...?" . She replies, "we adopted him and his family when he was a child in Burma. How is he doing?" 3. My daughter, who grew up in Central California, decided to attend college out of state. Her best friend, Meg, would take my daughter home with her during breaks because of the long distance back home to California. On one occasion, Meg's uncle states, "So, I understand we are related." Intrigued, my daughter asks how they could be related. "If your last name is _________, and your dad's name is _________, then your grandfather is Donald, his father was Walt, mother Ev.....and proceeded to name off our immediate up-line (to borrow a marketing term) all the way to the branching where their family name changed when their great grandmother married. The girls became cousins after being friends for years. 4. My most improbable event because of the ending....read on. Just before entering high school our family moved from southern California to central Pennsylvania. I attended a boarding academy there. In early Fall of my sophomore year, a busload of us students were on a club or band trip. As luck would have it, I got to sit with several very cute girls, chatting about this and that, and well, just about everything. Suddenly all the mannerisms of one of them reminded me of a former classmate I'd had a crush on in grade school back in California, a mere 4 years earlier. I turned to her and exclaimed, "sweetie, do you know who you remind me of??!! When I opened my mouth to utter the answer, what was heard was in the voice of one of the other new girls to the school: "Theresa ________!!!" she shot out in unison to my own "Theresa________!!!" "Wait!! Where do you know Theresa from??!!" California. "Wait!!, where do YOU know her from??!!" "Montana". It really IS a smaller world then we expect.
Wonderful video! I really enjoyed it. One quibble though. The Ariane 5 failure was not a math error. It was a software engineering failure. The program was designed correctly for the requirements they had for Ariane 4. The problem is that they didn't recheck it for the range of inputs that the Ariane 5 would produce. The failure would've been detected if they had simply simulated the launch. (IIRC, they did see it in some simulations but they just rebooted and ran it again. I could be wrong about this.) They had redundant data processing units in the rocket and they assumed that if there was a crash, the other units would take over. Unfortunately, all the computers were using the same inputs and the same software, so they all simultaneously crashed. This is a classic software engineering cautionary tale about the dangers of reusing software.
and an even greater one of taking shortcuts, and not looking into all the what ifs. cascading failures indicate an inherent overall software design fault

Here's one for the book. I learned in a highway design course that early on, they studied accident statistics and determined that, since accidents were more likely when driving on a curve or over a hill, that they could reduce the number of dangerous stretches of road by combining curves and hills whenever possible. This worked perfectly in achieving that result; of course that made the road even more dangerous.

Note that the people who made the invalid deduction might or might not have changed their minds. It is not as if there is a single cabal of engineers who make decisions about design methodology, and are the ones responsible for correcting their mistakes.
There is another road in Spain I think that is completely straight and has one of the highest accident rates in the world. It is a very long road.

When he showed the falling Jenga tower that required less energy because of the resonance, that was absolutely amazing.
You can simulate the same phenomenon in a bathtub full of water. If you shove your hands back and forth randomly, no meaningful waves will form. Only if you hit the resonance frequency of the tub (that is dependant on the size and shape of the tub) will a big wave form.
For normal sized tubs that means pushing way slower than your intuition tells you.

"Average means I'm above 50% of books"
Should we from now on call median a Parker average? I'm fine with that.
You raise an interesting point, except that he probably could have better explained. This is a skewed distribution, so in this case the average is in fact better than 50% of the books.
Actually, median, mean and mode can all be called average, which is where a lot of misleading statistics comes from. I read this in Darell Huff's excellent book "How to Lie with Statistics".
@@shambosaha9727 median, mean and mode can all be called average ONLY if the data you are looking at follows a normal distribution.
@@surfingbilly9654 Technically speaking, they can all be called average ALWAYS. They have the SAME VALUE if the distribution is Gaußian.
I used the median recently in a report and to avoid the confusion of talking about the 'average' value, and knowing that the audience would not have heard of the median, I referred to the result as the 'typical' value i.e. the typical number of days worked, rather than the average number of days worked.
I've been very pedantic regarding the "stars where the moon should be" for years now, the difference between me and Matt is that he makes people laugh about it and I make people want to throw things at my face.

Parker maths
I just recently started realising what Matt meant when he said that math is about "getting it wrong and working towards the right answer". That is exactly what my current course in Applied Mathematics is like - that course is about a bunch of super-complicated equations that simply cannot be solved exactly, and instead require a lot of trial and error with various approximation techniques.

@@skylerbirch8248 Because it's in England... literally NO ONE in England knows Texas IS "the lone star state"

I'm really sad more people didn't get the joke, but I can't honestly expect people in the UK to know the nicknames of the states when I don't even fully understand exactly what countries and regions "the UK" even is.
Parker is my favorite mathematician which is something I never thought I'd say about a mathematician xD.
Except he doesn't do what a mathematician should. He is rather a standup comedist.
And what "should" a mathematician do, exactly? You do realize that people can be more than one thing, right?
@ K W I know what you mean, but the logic of what you actually said doesn't work. If you never thought that "X is my favourite mathematician" was something you'd say about a mathematician, then that suggests you thought you'd say it about a non-mathmatician, which obviously is then a paradox.
@@MrDannyDetail I don't think never thinking to say "X is my favourite mathematician" about mathematicians implies that they would have thought it of non-mathematicians either. It definitely makes it ·strange· to specify mathematicians, but that doesn't necessitate that they would have thought about it at all.
"I would have never thought I would have a favourite member of set A that was in set A" is logically equivalent to "I would have never thought I would have a favourite member of set A", since any favourite one could have from set A must also ·be· in set A.
I think this is more of a linguistic question of what including that redundant detail implies of the speaker, rather than a question of logic. When it comes to language, including unnecessary details like that imply that there exists a possibility that something could've been otherwise, or at least that the speaker thinks so.
"I picked up a stone, and it was a stone" is completely true and logically valid, but the fact that the second clause is in there makes it sound like it the speaker is surprised that the stone was a stone, which is an illogical thing to be surprised by.
@@liebert234 Great response! As you say it's a linguistic amibiguity that depends on whether you consider the 'about a mathematician' part to be unnecessary repetition of the same fact, or a new piece of information that's critical to the intended meaning, which in turn depends on how the person says it.
Perhaps I misspoke when using the word 'logic', but I'm not sure what other word could be used in it's place. I mean the deduction that the repetition would not be there unless it conveyed the possibility that something could have been otherwise, is itself a form of logic. I guess it only fails to be true logic because it would be an assumption rather than a hard fact.
Hats off to you, Matt! Loved it, esp. the ending -- @ 1:07:14 "...and I'm like, yeah, people have to earn the book"......yes, Matt, I'll do that.....thank you for this superb video!
I remember his last lecture. Good to see you again matt.
To speak to the probability stories in this video: My wife is originally from Utah, and her dad grew up in American Fork. After we moved to the Portland, Oregon area, we were in a mall where we overheard a woman talking to a store clerk about her upcoming voyage to Utah. We had just moved to Oregon (literally a few months before), and we interjected ourselves into the conversation saying that we had just moved from Utah and was curious as to where she was going. She mentioned where she was going, but she also happened to mention that she lived in American Fork for a while. My wife said, "That's where my dad's from!" She asked his name, and when my wife told her his name, she exclaimed, "I dated your dad in junior high school!"
We were BLOWN AWAY. Right then, my wife called her dad, and they talked for about twenty minutes on the phone in the most impromptu lovers' reunion I had ever experienced. It still brings a smile to my face.
Mmm... it's no longer something that happens to somebody in the world, but now we need to take into account it happening to a viewer of Mats video. That is a much lower chance.
@@renedekker9806 You have to increase the probability by a factor of how many strange coincidences you allow, as well as distance from the teller of the story. Matt's specific examples revolved around pictures shown to those about to get married. Now we're up to meeting someone who had a passing relationship with n degrees of separation. Each of these makes things exponentially more probable.
Last summer a young lady I had never met had her small puppy named "Stevie Nix" chase my young kitten named "Little Richard" up a tree. Strange coincidence? Sure, but that's not the real strange coincidence. After finally retrieving poor Little Richard, we got to talking and discovered that we had both gone to the same high school - 4500 km away. Albeit 40 years apart
That was a day to play the lottery.
@@MrSJPowell Not to mention that we have to factor in what constitutes a "weird occurence".
If there are no rules set up before hand, literally anything goes.
While it is unlikely that one specifik freak occurrence happens to one person, and it is likely that it will happen to someone at least once, it is also,. by the same logic and reasoning, impossible to go through life without experiencing at least one weird event as an individual.
You just need to look for the patterns.
Small number of people in the same location. And its easy. Only 300+million outta a few billion so what are the odds? Remember most Americans never leave the States. East coast to West coast its not even the entire continent.
The jenga buildings part really resonated with me... 😋
I honestly thought the wheel was rigged, as the audience were turning it clockwise and matt was spinning it anti-clockwise and there was some mechanism that only worked in one direction.
What is the odds of it landing on probability?
more pertinently what are the odds of a complex clockwise/anti-clockwise fixing mechanism versus matt just re spinning till he get's green and editing the video
But to answer your question, it's 1 in 5, or for 3 probability in a row I believe it's 1 in 125 (1 in 5^3)
i thought the same thing.
and after he said the "dont believe everything you see on the internet" thing, i thought "but what if the video ISNT edited?"
3 _green_ is 1 in 125
but 3 _same_ in a row is 1 in 25
I’m a magician. Probability is my game. I was blown away, that they did several takes to make this happen :)
I just assumed the spinner was rigged. Of course he'd go about it the Parker way--don't cheat, just repeat.
Well, James Grime did it with the 10 coin flips in a row video.
Love your avatar
it was a little suspect that it stopped on the purple before the green on the last one. that (at least in my mind) confirmed the rigging
45:15 Another fact that has to be considered is that the projections that the maps used to pinpoint the locations could also affect the shape. The previous researcher could have even selected the same locations on a different kind of a projection and identified another pattern. They're just random conincidents.
Omg, by the third one, I knew something was up but I thought it was a weighted wheel or something 😂
Also the props he had on him.
Nothing was up. That's why he said he'd never use the wheel again, because he wanted to bring up something else than probability 3 times.

I used to be a C++ software engineer. Before that I was an Ada software engineer. The Ada language has built in checks, one of which is a constraint error.

Matt, I'm from Texas and it's obvious that star is where it is from gravitational lensing. On an unrelated note, I'm not sure how to convey in text when my voice clearly indicates I'm grasping at straws.
james jones it’s obvious. * tips hat *
This is because in Texas the moon is way bigger
I don't think gravitational lensing can explain the gradient background showing through...
Perhaps the Earth's shadow on the moon merely coincidentally resembles the plate's background very, very closely.

There is a Korean show on netflix called "my Mister" where the lead plays a civil engineer who designs buildings, and it mentions a building he designed where a gym caused problems and the damping mechanism he put in to counter it.
Mildly interesting probability story. I once visited Tokyo and during a wild night out lost my mobile phone. The next day my friend received a phonecall to come and pick up my phone. Turns out, it had been picked up by someone I had gone to primary school with 15 years prior who had recognised me in the photos on my phone, had contacted back to our mutual home country to get all the relevant phone numbers and then called through to arrange a meeting spot.

When it fell on "probability" the second time I joked to myself, "what's the probability of that!?". When it happened the third time I thought, surely it's rigged, but then I remembered you spinning it at the beginning and then you spun it again. Once you revealed the truth, it put my mind at ease, "oh thank God, it's just someone on the internet lying to me.".
The moment the second probability came up in the vid my suspicion was that it was rigged....and it was...just not when I thought it was and how I thought it would have been.
Yeah id have weighted the spinner.
I gather people for a good cause:
I wanna provide people with Links leading to bad or toxic people.
Mobber, Racists, Sexists, Bullies, more. I got the Links and i
need help with reporting them.
People know RUclips has Problems, but... but... I mean... complaining about the State of the world is nice
and dandy, but... how about acting? Doing something?
So i made a Wiki where i store Links for all to use.
You can at least pre-emptive 'block user' regarding the
Racists and all those, but you can also
do one thing more and report them, so
YT becomes a better place.
I know this was random and also overly summarized, but
think about it and consider. You can make a difference.
Means: I gathered and confirmed many Links. And made a Wiki to
provide the Public with them. Wanna help, too?
This is perhaps one of the hardest things to teach: that it's okay to make mistakes.
The first solution you come to doesn't matter. What does matter is how you came to that solution, and what you do to make subsequent solutions better.

There is no such thing as a single dice. It is called a die. Don't be fooled by those who insist that you should never say die.
Times are changing - en.oxforddictionaries.com/definition/dice - "Historically, dice is the plural of die, but in modern standard English dice is both the singular and the plural: throw the dice could mean a reference to either one or more than one dice."
Both are correct nowadays
People really should say "dice" for the singular form and "dices" for the plural form.
The only reason why people are uncomfortable with those forms is because those aren't the official spellings.
Wait, if dice is plural and die is singular, does that mean rice is plural and rie is singular?

Not really, most languages are just arbitrary like that.
Ideally, all words should use regular forms, since this would be much more convenient, but reality is always more complex than that.

I found this video while aimlessly browsing (It's COVID time and I'm bored). Well, it could be a turning point in my life, or not... But either way, thank you so much for sharing your time, energy, friends, and family with the rest of us. For now, my lips are frozen in the shape of a big warm smile.
He does such a good job with his lectures. So much fun to watch!
Can’t believe i just watched an hour long math vid
Matt's a real gateway drug. First this talk, then this one - ruclips.net/video/1wAaI_6b9JE/видео.html, then before you know it, you'll be all the way to this one - ruclips.net/video/iHKa8F-RsEM/видео.html

I left immediately after posting this after hearing him call "math" "maths" its just annoying.
Although I will probably (pun intended) never be a huge maths enthusiast myself. I can appreciate the fun you can do with it and the important part it plays in the world we live in. Thanks for this interesting video! My younger self would've never believed I'd spend an entire hour watching a video about math in my spare time and enjoy it ;-).
Is the second book going to be called “Humble Tau”?
9:55 I love how you just gloss right over that "a lot of my friends procreate" joke. Hidden gem.

Thank you for that joke. Got a jolly chuckle and made my day brighter
When Maths Goes Wrong
*Parker square intensifies*
When Matt goes wrong...?
impossible
"I don't want to live on the moon" seems oddly appropriate since I was just watching Umbrella Academy.
Great Presentation - I like math because no matter how long it takes me to get to a solution, the math never gets mad or frustrated - it patiently waits for me to succeed!
11:30 "That's not a bad angle for the shuttle taking off". Except the shuttle takes off vertically.
It has to leave the atmosphere at an angle or else the friction from the atmosphere burns up the shuttle. Like how it is softer to dive into a pool than it is to do a cannon ball.
@@joeydunn7727 Agreed - what you need to achieve is velocity parallel to the Earths surface if you want to go into orbit.
When Matt first explained that each of the dies could beat the next one in a circle, I immediately thought of Rock Paper Scissors Lizard Spock

Behind the Scenes: When Matts go Wrong
Cam Brown the Parker Square
I have 4 probability events similar to the young couple who were strangers in the same photograph as children:
1. My sister was visiting Hawaii with a girlfriend and while there, unexpectedly met the husband of another friend. She recognized him. Turns out that she had met him 40 years earlier at his house when we were all children. We were at their house to encounter buggy driving with Shettland ponies. I was 8. Why she remembered the boy and this event was because of her keen interest in the beautiful drawing of a male African lion's head on the wall of this boy's bedroom (which he had drawn). She was a budding artist at the time. Fast forward up to her trip to Hawaii and recognizing him although he was thoroughly stumped who this woman was who was describing his childhood home to great detail back in California 1966.
2. My niece was getting married in Washington state into a family of preachers. The the family tree branch this young man was on was lateral to the one that I and my siblings were familiar with, but with the same sir name and same grandmother. At the family dinner prior to the wedding day, I was seated at the patriarchal table next to the matriarch of the family, herself. We strike up conversation and she asks me where I live. (central California) She says, "Is that a fact", well do you know my dear friend Victor D.?" I reply, astonished, "why, yes I know him, in fact we play music at church together almost every week!!... How do you...?" . She replies, "we adopted him and his family when he was a child in Burma. How is he doing?"
3. My daughter, who grew up in Central California, decided to attend college out of state. Her best friend, Meg, would take my daughter home with her during breaks because of the long distance back home to California. On one occasion, Meg's uncle states, "So, I understand we are related." Intrigued, my daughter asks how they could be related.
"If your last name is _________, and your dad's name is _________, then your grandfather is Donald, his father was Walt, mother Ev.....and proceeded to name off our immediate up-line (to borrow a marketing term) all the way to the branching where their family name changed when their great grandmother married. The girls became cousins after being friends for years.
4. My most improbable event because of the ending....read on.
Just before entering high school our family moved from southern California to central Pennsylvania. I attended a boarding academy there. In early Fall of my sophomore year, a busload of us students were on a club or band trip. As luck would have it, I got to sit with several very cute girls, chatting about this and that, and well, just about everything. Suddenly all the mannerisms of one of them reminded me of a former classmate I'd had a crush on in grade school back in California, a mere 4 years earlier. I turned to her and exclaimed, "sweetie, do you know who you remind me of??!! When I opened my mouth to utter the answer, what was heard was in the voice of one of the other new girls to the school: "Theresa ________!!!" she shot out in unison to my own "Theresa________!!!" "Wait!! Where do you know Theresa from??!!" California. "Wait!!, where do YOU know her from??!!" "Montana". It really IS a smaller world then we expect.
Matt: I flipped this specific coin 10,000 times.
Me: Of course you did.
I can only hope he rigged some automatic system. But I know he didn't xD
Wonderful video! I really enjoyed it.
One quibble though. The Ariane 5 failure was not a math error. It was a software engineering failure. The program was designed correctly for the requirements they had for Ariane 4. The problem is that they didn't recheck it for the range of inputs that the Ariane 5 would produce. The failure would've been detected if they had simply simulated the launch. (IIRC, they did see it in some simulations but they just rebooted and ran it again. I could be wrong about this.)
They had redundant data processing units in the rocket and they assumed that if there was a crash, the other units would take over. Unfortunately, all the computers were using the same inputs and the same software, so they all simultaneously crashed.
This is a classic software engineering cautionary tale about the dangers of reusing software.
and an even greater one of taking shortcuts, and not looking into all the what ifs. cascading failures indicate an inherent overall software design fault
Computer software is mathematics.

No. Programming is technical writing.
It is a form of literature.
