      UH problem with the Heads-Tails-Tails game he played: NONE OF HIS PREDICTIONS WERE A SET OF THREE (he had no prediction that was TTT or HHH) Well given 8 sets of probabilities, 2 of those 8 were consecutive 3-of-a-kind, but none of HIS predictions were three of a kind. Well in a continuous string of binary (H / T) the probability of producing a string of 3-of-a-kind is SIGNIFICANTLY lower than the probability of producing a 2-of-a-kind scenario.
      only TWICE in that entire string, are there any 3-of-a-kinds! Yet how many examples of two of a kinds are there? 14
      Yet this he does not explain.
      He doesnt even actually understand why his game makes him the winner every time. Or he DOES understand and he is trying to pull a fast one on you.
      If two of his predictions were 3-of-a-kind (TTT or HHH) then he would NOT have won that game, because not a single 3-of-a-kind ever came up, so at least 2 of his predictions would have been wrong instead of right, UNLESS he simply reversed the two 3-of-a-kind predictions (he predicted TTT for HHH, and HHH for TTT) which would have evened out his odds again, in which case the odds of him winning go back to 50% and whether or not he won would be entirely based on the moment that he decided to end the game. A few more tosses and every victory becomes a loss.
      You people should really come to understand this or you will lose a lot of money gambling

    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.

    • roadie3124
      roadie3124 Ай бұрын

      We have some long, straight roads here in Australia and one of the design goals on many of them was to make them appear absolutely straight to drivers. Since they were laid out before GPS technology, it was necessary to make occasional corrections. These were usually made at the peak of a hill so that drivers couldn't get a long view showing the kinks.

      @Ashmeed Mohammed 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.

      @Michael McKenzie Indiginous English people are more likely to identify as British than any of the other nations. In addition we have a majority of non indigenous people and they are more likely to identify as British.
      However of the 68 million people living in the UK alone around 56 million live in England.
      That is a vast majority.

      ​@Gareth Farman vast majority is a stretch. Speaking strictly about people who are residents of the UK, 37.6 million out of 67 million identify as English.

      @Voor Naam I am English. Since the final fall of the British Empire in 1997 the vast majority of British people are English. From about either if 1979 or 1982 the English made up the majority of British people.
      Gibratarians, Falklanders and Bermudans are British from Overseas Territories. Channel Islanders and Manx are British from Crown Dependencies Scots and Cymraeg are British from the UK and they are not English.
      However the language we all have in common is called English. Whether you are in the UK, USA, Canada, Australia or New Zealand .... the language is called English.
      Scotland speaks 4 languages, Scots Gealic, English, Doric and Scots. The latter 2 are based on North Eastern English with varying degrees of Gaelic and Norse and Modern English influences. We still call it Scots and not Northumbrian or Middle North Eastern English because Scots is the name of the language.
      We should never refer to the UK as England or the Netherlands as Holland. However both England and Holland still exist.

    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.

      @Ray Habenicht 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.

    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.

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.

      The single golden star on a blue background on the Texas state flag signified Texas as an independent republic and was a reminder of the state’s struggle for independence from Mexico. The “Lone Star” can be found on the Texas State Flag and on the Texas State Seal today. It is found almost everywhere in Texas - on bridges and even on the huge ferris wheel at the Texas State Fair known as the Texas Star. The Lone Star State nickname became the official nickname of the state on June 19, 2015. Texas will vote to become part of Mexico again as soon as enough people that Democrats are allowing to illegally enter the country get the right to vote. Texas is the only state in the union that can legally secede.

First he sent someone to the nearest house and set off a test detonation. The observer and householder were happy that there was no effect on the house or it's contents so Bates carried on with the sequence. He had hardly started, however, when a lady came running and shouting from further along the road saying that her home was being shaken badly: resonance and wavelengths!

    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.

      I come from a small village in Germany (just about 2,000 people living there) and went to university a couple of hundred kilometers away. I had rented a room in an apartment with a few other students. When one of them asked me where exactly I come from, not only did she recognize the name of the village (already quite unusual) - it turned out that her parents had lived in the house opposite ours 30 or 40 years ago! (These are houses where only one family lives, not apartment blocks, mind you.)

      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.

    What I really like about coincidence. In addition to a specific event being very likely to happen given enough people, it is also certain that some incredibly unlikely events will happen to every person. Simply because we have the chance to experience an anomaly thousands of times every day without even realising it!

Last night I was in bed, and somehow I was thinking about how people are so certain of the truth, yet we always ask if it will be heads or tails, when in reality it has another option.

      @BlankPaper Well no, because the interaction wouldn't have ended there, had it actually been double-sided. The question is not redundant, as if it had been a yes, the person could have said something to the effect of "I pick whatever side is on the coin", or simply asked "Which side is doubled" and then proceeded to pick that one. It would only have been redundant, if the answer was "Yes, it is double-sided" and then they simply went on to pick whatever anyways without inquiring or thinking further

    I've struggled with math all my life. I'm a writer. It infuriates me that I was barred from getting into a 4-year university due to the entry requirement for intermediate algebra! (This as a mid-life student!--by that time, I'd been running a household, raising children, volunteering with Girl Scouts as a troop leader and day-camp coordinator...I feel I already knew how to "think logically," which was the excuse given for the math requirement!) As I said, I'm a writer. Why would a writer need math? I write humor, blank verse poems, travel essays, and the like. I do not write technical manuals or anything remotely similar. I don't need math. The human brain being how it is, the oft-repeated adage of "use it or lose it" applies. If I had learned algebra, I would never have a need to use it, therefore I'd have lost it, and the time spent studying it would have been wasted. Therefore, why would I want to spend the time and effort learning a subject for which I'd have no future use, and would end up forgetting?! Answer: I wouldn't. So, my education stopped with an Associate's degree in liberal arts from a 2-year community college. Administrators should make reasonable requirements based on the students' planned future occupations.
    Also, I don't trust percentages. As a member of a parent group trying to save a school threatened with closure, we learned that you use percentages if you want to make something sound BIGGER than it is. To wit: we surveyed the teachers of said school, and found that 14% of them would leave the school district and teach elsewhere were that school to be closed. Fourteen percent!!! Guess what? That fourteen percent amounted to a single teacher!!! But by stating it as a percentage, we were able to manipulate the facts without lying, and make the situation sound more dire than it was. No, percentages are not to be trusted!
    (Oh, and here in the USA, hearing people refer to "maths" is grating. to us, it's a singular word! It's either "math," or, if you insist on using the plural, then don't shorten the word, and call it "mathematics" instead! Thank you! ;-) )
    Probability is like gambling chances--my late husband was listening to his step father brag about winning $25K at the casino. Dad was not happy when asked, "How much did you spend to win that?" LOL

If I said 467 out of 934 people like cheese, that may be hard to visualize, but 50% is much easier! The example you gave is an abuse of a method, where the numbers are used to obscure the truth

    When I was 10, my mother, my brother and I went to a place called Kemer in Turkey for a couple of weeks. It was a really good vacation and next year we decided to go to Turkey again. We were looking at possible cities to go to in a catalogue, and as we came upon Kemer we stopped to reminisce a bit and looked at the aerial photo... and noticed "Hey, the hotel the picked for this town looks a lot like the one we stayed in... Actually, it's the same one! And look at that, those three people you can see at a table look like a woman and two boys. They could be us. Actually, what clothes were you wearing? And the hair colors match. And that's our table! THAT'S US!!" So the same people who had their picture taken unawares were the ones who the year after sat together and saw themselves.

    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.

      @BlankPaper Yes this is a conundrum that has haunted me for some time...
      If only the people who recognize the wisdom of limited reproduction abstain from gratuitous replication, they will ultimately be outnumbered by those who reproduce with no thought of the consequences.
      Unfortunately there is no obvious solution to this dilemma, as any attempt to limit the "reproductive rights" of the masses would seem dystopian and heavy-handed.
      The alternate civilization envisioned by Robert J. Sawyer in his brilliant three-part series The Neanderthal Parallax had some very clever societal adaptations to both limit population and heighten the average IQ of their populace, but it is hard to imagine anything like that ever happening in our world.

      Procreation is a funny thing... Those who procreate more, think less. Those who think more, think about NOT procreating as much, just "enough", if at all. The people breeding like bunnies, don't think much at all.
      Our problem, as a society, is that we base OUR intelligence, off a few rare individuals or "teams", as if WE are that smart. Most of the brilliant minds in history, are honestly not brilliant. History is in the hands of those who write about it. Most historians are not bright, but profess to be a writer of brilliance. (That is not a derogatory statement, but a fact. Just as teachers are rarely ever "applied" in what they teach. There is no time to teach if you are doing, and no time to do, if you are teaching. Teachers usually work on providing tools for great minds to use. The hope is that one of those who was given tools, will actually be a "great mind". The reality is that most people rarely use the tools they are given and the greatest minds never needed the tools to begin with. It's a lovely, ironic, catch-22.)

      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.
