  1. No, that is not logically true, in other words something that cannot be not true. Also mathematical statements are ruled out, such as 2+2=4. I know, Plato is such a grouch !
  2. One minute before noon , you have an INFINITE number of ping pong balls outside a room, all numbered . You throw in balls 1 +2, immediately ball 1 is thrown back out. Half a minute before noon 3+4 are thrown in and number 2 thrown out. At a quarter of a minute to noon balls 5+6 are thrown in and number 3 is thrown out. At an eighth of a minute to noon 7+8 in and 4 out ad infinitum.... How many balls are in the room at Noon ?
  3. Light bulb problem- clue - the room has furniture in it.
  4. The Lord Plato is guarding a bridge over a river when Socrates appears. Socrates begs to be allowed passage. Plato bellows " If the next thing you say is true I will allow passage, but if the next thing you say is false I will throw you in the water, self referential statements like " I like potatoes, or my name is Socrates don't count, nor do statements like ,grass is green, it must be irrefutable provable and logically true" Socrates being clever says; " You will throw me in the water" If Plato does indeed throw Socrates in the water, then Socrates spoke truly and shouldn't have been thrown in, but if he doesn't throw him in, Socrates spoke falsely and should have gone in! Either way Plato is stuffed!! But hang on, Plato cannot fulfil his promise, it's logically impossible, so he has no obligation to keep his promise, and assuming free will can throw Socrates in the river if he pleases. It is argued that statements about future intentions cannot have a truth or false value. Socrates saying " You will throw me in the water " is neither true or false. However Socrates could have said something avoiding future dependant language that would have avoided a dowsing in the river. What?
  5. The simplest answer is that at the time the Lawyer instigated the lawsuit the Student hasn't won a case, so his case is thrown out. The Student has now won a case, and a second lawsuit instigated by the Lawyer will surely succeed.
  6. Outside a room on the wall are three numbered light switches that operate three light bulbs inside the room. The door is solid with no window in it. Is it possible to identify which switch operates each bulb ? You may only enter the room ONCE after doing whatever you want with the switches and you can only touch TWO of the three switches. You are accompanying a lion and a goat on a journey , also you have a huge cabbage. You come to a river and see a rowing boat moored ready for use. However you can only take across one animal at a time, or indeed the cabbage. The boat is only big enough to carry you and one of the other three. You must get all three across one at a time, HOWEVER, if you leave the lion alone with the goat it will eat it, also if you leave the goat with the cabbage it will eat it. How can you get all three across safely, remembering that you have to be on board the boat each time you cross the river, either alone, or along with one animal or the cabbage. You can cross the river any number of times. PRISONER HAT PUZZLE.
  7. PARADOX OF THE RAVENS. All ravens are black , another clumsy way of saying this is ' All non black things are non ravens ' These hypothesis say the same things. The equivalence rule in logic states that anything confirming one hypothesis automatically confirms an equivalent hypothesis. My white pen confirms the second hypothesis, ie it's not black or a raven, but surely it can't confirm that all ravens are black. The details of this paradox discussed here; The Sleeping Beauty Puzzle. Not easy to get your head around this. After seeing this video, my guess is that credence and probability are being conflated. Beauty doesn't know what day it is, but there's two tails awakening to one heads awakening so her credence should be 1 in 3.
  8. A thread for any logical puzzles or paradoxes you want to try out on others. Paradoxes are fun, if a bit philosophical. Here's a few to start. The Sheriff of Tombstone Arizona rides into town on thursday, opens his office up, he has a bed in there and only stays in town for one night. But when he leaves it's Sunday. How come? Two guys are in a restaurant, at the end of the meal the waiter gives them the bill, for £30. The internet is down, so they have to pay cash. Each has exactly £15 only on them...luckily. The waiter takes the money and hands it to the manager who is working the till. The manager examines the bill and says the bill is for £27 only, and instructs the waiter to.hand back £3. On his way back to the men he decides to pocket £1, and tell the men the bill cost £28. The two men leave with their £1 each. They both entered with £15, and left with £1 ,spending £14 each which equals £28, plus the £1 the waiter pilfered equals £29. Who has the missing pound ? THE GOD /BOULDER PARADOX. God by definition can do anything, nothing is beyond such a being. Can God create a boulder so heavy that He cannot lift it? If he can, then there's something he cannot do ie lift the boulder, if he can't then there's something he cannot do . Either way the definition of God is in trouble. THE LAWYER/STUDENT PUZZLE A lawyer helps a student qualify to become a lawyer, but generously waives his fee, for now. The student will pay the tuition fee when he has won his first case. Months go by and the student , now qualified, hasn't taken up a single case. The Lawyer anxious for his fee sues the Student , reasoning that if the court finds for him,he has won his case, and if he loses then the Student has won a case, either way the Student must pay up. The Student reasons that if the court finds for the tutor, he has lost and needn't pay, and if he wins then the tutor's case is thrown out and he still needn't pay. Who is right, what should the court do?
  9. No complaints about today's EPL matches. Leeds yeah! Manchester United
  10. And I said yesterday the BBC RL coverage is champion for a regional sport. If you had your way a typical BBC1 evening would look like this. 5.15 Pointless Rugby League. Contestants test their RL knowledge for prizes. Today's prize, a season ticket to Hunslet RLFC 6.OO News 6.30 RL Antique Roadshow The team of Phil Clarke and John Wells visit Dewsbury to see what RL memorabilia can be unearthed. 7.30 The RL One Show. Terry and Baz host another topical magazine edition of the popular show, today looking at fashion and food. What to wear at RL games, and what is the best food to eat while watching the nation's favourite sport. 8.00 The Salforders. Soap continues with those heartwarming Salford folk.at the AJ Bell who have come up with another plan to increase attendances. Meanwhile rival gang ," the Nevilles" at Salford FC plan a counter strike. Top drama. 8.30 Strictly Rugby League Semi final of dance competition, this week Leigh vs Featherstone. Players and their wives take to the floor. Judges Brian Carney, John Kear, and Dave Woods. 9.00 The Toronto Empire. Comedy as Chris Barrie plays Gordon Brittas formerly a leisure centre manager, now managing Toronto Wolfpack, trying to establish themselves in Super League. Will the 10th attempt succeed or will mayhem ensue 9.30 The New Generation Game. Eorl Crabtree hosts couples playing RL themed games. What will be on the Prize Conveyor Belt tonight? Leeds Rhinos shirt, cuddly Brian Carney toy.. 10.00 News 10.35 - 10.40 Five minute slot for football results of the last week, in case anyone cares. 10.45 World Cup Qualifying Match On the red button for those who care, England vs Germany World Cup football semi final from Brazil . On the main channel Rugby League World Cup qualifier Pitcairn Islands vs Tuvulu.
  11. The fermi paradox deals with the absence of alien life despite overwhelming likelihood of the existence of such life.
  12. I can recommend Isaac Asimov's book Extraterrestrial Civilizations for a serious discussion about the possibility of alien life. He used scientific methods and the principle of mediocrity to try and come up with a figure. The principle of mediocrity is assuming that our Sun and Earth are average, nothing amazingly unique in their composition or placement. On other words there's other Suns the same size as ours, other planets in orbit at the same or similar distance to these Suns, in the goldilocks zone, not too hot not too cold. Here's some figures; 1. No. of stars in our galaxy 300,000,000,000 2. No. of planetary systems in our galaxy 280,000,000,000 3. No. of planetary systems in our galaxy that circle Sunlike stars 75, 000,000,000 4. No. of Sunlike stars in our galaxy with a useful ecosphere 52,000,000,000 5. No. of second generation, Population 1 Sunlike stars in our galaxy with a useful ecosphere 5 , 200, 000,000 Second generation = stars formed from exploding older stars producing elements such as ices, rocks metals to produce solar systems similar to ours. Population 2 stars in galaxy centre, bathed in radiation unstable and unsuitable for life. 6. No. of second generation population 1 stars in our galaxy with a useful ecosphere and a planet circling within that ecosphere. 2 , 600, 000,000 7. As above , but the planet is Earthlike, assuming 50% of planets in ecosphere are chemically similar and have oceans of water ,vital for life 1, 300,000,000 8. No. of habitable planets in our galaxy. 650, 000,000 9. No. of life bearing planets 600, 000,000 10. No. of planets in our galaxy bearing multicellular life. 433, 000,000 Earth was 4 billion years old , a third of its life span gone before complex life existed. Using mediocrity principle one third are too young to have complex life, therefore two thirds do. 11. No. of planets in our galaxy bearing rich land life. 416, 000,000 Principle of mediocrity, land life appeared on Earth when 4.3 billion years old. 36% of its lifetime, therefore 64% have land life. 12. No. of planets with technological civilizations 390, 000,000 Civilization appeared when roughly Earth was 40% through its lifetime , after 4, 600, 000,000 years. Therefore principle of mediocrity, 40% of planets are too young, 60% are old enough. 13. No. of planets in our galaxy on which a technological civilization is NOW IN BEING 530,000. This seems a lot, but this figure is ONLY 0.0407% of figure no.7 For full details, and the answer to WHERE IS EVERYBODY. Read the book.
  13. Astronomers talk about Venusian atmosphere. Venus = Venusian, the clue is in the name. Dictionary Search for a word Venusian /vɪˈnjuːzɪən/ adjective ASTRONOMY relating to or characteristic of the planet Venus. "a Venusian orbit" noun a hypothetical or fictional inhabitant of the planet Venus. "a bald, purple Venusian"
  14. Don't know about Venutians, Venusians maybe.
  15. Typical BBC 1 schedule, if some on here got their way. 5.15 Pointless Rugby League. Contestants test their RL knowledge for prizes. Today's prize, a season ticket to Hunslet RLFC 6.OO News 6.30 RL Antique Roadshow The team of Phil Clarke and John Wells visit Dewsbury to see what RL memorabilia can be unearthed. 7.30 The RL One Show.

  16. BBC money is not THEIRS , it's OURS, the licence payers and tax payers. RL deserves to have spent on it an amount commensurate to the number of RL fans who are licence payers , if the majority of licence payers were RL fans then the situation would be different, but they're not. In fact the majority of licence payers are probably not even sports fans, hence lots of other programmes. There's a conceit in your argument that basically says, put RL in front of the bl00dy people, they'll love it, it's irresistible , billions for soccer....that's (sic) carp, RL deserves billions. Here's an analogy; A teacher in a classroom has 50 pupils and has to decide which treat to take them to. Each pupil puts in 5p and gives a preference as to where they go, museum, fairground or zoo. 30 opt for fairground, 18 for zoo and 2 for museum. The teacher says " well I know it's not the most popular but the museum is fantastic and is in financial trouble, so we're going there" You get my drift....the teacher is the BBC, the pupils the licence payers and the museum is RL. Did the teacher act correctly?
  17. Yep, the BBC have steadfastly ignored RL by broadcasting the Challenge Cup for decades!!!
  18. 100% agree with this, in fact the BBC have shown if a hitherto minority sport becomes big news it will broadcast it as it is obliged to do. I'm thinking of women's football and netball. The women's WC football got the nation to take notice, I personally didn't watch, but nevertheless it got good ratings and now there's more of it on BBC, SKY BT all recognized there was an audience and responded. So if RL has a good WC and people respond positively and want more, then it's a whole new situation. RL for a minority sport does well, I don't see any field Hockey on the BBC, or British Basketball or Ice Hockey, RL has nothing to complain about. If any sport has something to complain about it's Cricket, the BBC shamefully abandoned it, except for TMS. It's even possible to make a case that the BBC should have bid to show one EPL match a week.on FTA, but the cost would be too astronomical, and why , because football can guarantee audiences and is a Sky subscription driver thus can ask for vast tv deals, but RL can't. I fully understand how aggravating that is , how deeply hurtful it is, but that's the way of it.
  19. The point is the other things they according to you " waste" money on are ratings winners. The Beeb's money is from licence payers and government subsidies ie. license payers taxes.RL does very very very well considering it is played in one part of the country. To spend big money on a national RL contract is as wasteful as showing the Highland Games nationally. If next year's WC generates national interest throughout the nation, ah then it's a new situation, it's up to RL to prove itself as a popular national interest sport. Just saying " hey we're fantastic, we're deserving, give us some dosh "doesn't cut the mustard.
  20. Liqueur chocolates, I've done it, really felt ill after a dozen or so.
  21. Glass half empty. Glass half full - Burnley, remarkable job by Sean Dyche, Everton, James Rodriguez signing, good few years for Fleetwood, Accrington and Salford . Though I don't expect the Neville brothers to be smiling at 10.15 tonight.
  22. If it does, then the dates will have to be shifted back a week or so as the Qatar World Cup starts 21 November 2022, and our final scheduled for Nov 27 2021.
  23. The iconic ball grab in British sporting history.
