@laughchem @realN0N4M3 @GMIgorSmirnov That sounds like a challenge. Just like: "Can you checkmate with all your pieces on their starting squares?" (search for chess vibes' "I sacrificed 8 queens in one game"). Anyway: Challenge accepted. I'll try to promote to a bishop if I still have one of that color.

@realN0N4M3 @GMIgorSmirnov Or two bishops on the same color

Funniest answer wins!

@DJSnM Nope! Even today there is only one living apollo astronaut who had flown around the moon and not landed. That number can only go down: it seems very unlikely that they can restart the apollo program.

Up until yesterday there was only one living Apollo astronaut who'd flown around the moon but not landed, Fred Haise from Apollo 13. Now we have 4 new people in that club.

@Ravenismeee Pong.

Without telling me your age… what was the very FIRST video game you ever played?

@luiscabrejo @MathGuyTFL You introduced the solution a=0 by multiplying both sides by a, or zero in this case. I disagree that division by 0 is always wrong. Sin(x) /x = 1 has imho solution x=0.

@MathGuyTFL a×a=25a a = 0, a=25

Solve for a.

@pmcafrica Nowadays, they put the rails under tension, so that they would remain in tension (i.e not buckle) under the hottest expected conditions.

I thought those gaps were needed to allow for expansion to prevent the tracks from warping and derailling the train 🤷‍♂️

@DJSnM @CJHandmer Hit "paper" with enough laser radiation, and it doesn't burn. It evaporates! Gives plenty of "mess" in the machine when it solidifies again.

@CJHandmer The problem is if you hit toast with too much intensity the moisture explodes and so you don't get that nice toasty surface.

I need a machine that can toast bread with a xenon flash bulb in 10 milliseconds.

@Jo1ey1 @Gosleepriya In your post you omitted "0" as a possible digit. Your result is still valid though.

@Gosleepriya We have numbers: 1,2,3,4,5,6,7,8,9 It cant be 5,8,3 so remaining: 1,2,4,6,7,9 It cant be 5,6, 4 or 9 so 2 is the last number 1 and 7 are the 2 numbers 1 has to be middle number since the first 1 is wrongly placed 712 is answer

Crack the password let's try if you're genius 0.0001 % will crack the password

@FreyaHolmer Haha! Absolutely correct in this instance. A friend is called "Peer". Probably from Peter with the T gone missing. In Dutch peer is also "pear". Somehow it took me some 20 years before I made the connection. To me Peer, the person was completely different from peer, the fruit.

this isn't bait!! you legit don't have to know the linguistic connection in order to use a word like I'm sure some of you haven't yet realized "maybe" is a compound of "may be"

oh my god I just realized it's called an "equation" because it's got an equals sign that's equating two things

@caspar_ludbrook @GMIgorSmirnov My computer recommends B4 as the best move for black. Essentially all possible moves lead to mate-in-one, so it doesn't matter what you do. But for the puzzle, taking, or not taking the bishop is what counts.

@GMIgorSmirnov B-h6 KxB, Q-H8#

Can you solve this puzzle in 60 sec? White Mates In 2 🤔🤔

@badger69420 @GMIgorSmirnov Then knight F7 prevents mate on the next move. Sure, you then take the knight and it is very easy to mate in one or two moves, but the assignment was mate in two not mate in 3 or 4.

@GMIgorSmirnov Move the king

@WyattListon @DJSnM "faster landing gear" is not the case. They needed authorization (and possible plane modification) to put the landing gear out at a higher speed. All this to match the orbiter's speed and glide angle.

@DJSnM if the t38 can sustain a glide at such low speeds, why would it need faster landing gear and special brakes? either they modded the airframe or apparently the plane was built wrong? something about this does not add up IMO

When the space shuttle landed it would be flanked by T-38 chase planes flying low with their undercarriage down, not because they were planning to land, but because they needed the extra drag to match the rapid descent of the space shuttle. This required some modification to increase the gear deployment speed, and the shuttle chasing T-38's also had larger speed brakes to help them reach the shuttle as it descended the last 30,000' to landing.

@WyattListon @DJSnM Without engines a plane glides down at a certain angle. You want that to be as shallow as possible as it determines your fuel efficiency. If you try to go steeper, you speed up. If you're supposed to "follow" the shuttle, you need some way to not go faster and still go down.

@jmonteen @GMIgorSmirnov Igor's puzzles are interesting. I've seen several now that have the opponent having 4-5 different moves, each having a "mate-in-one" response from you. So in this case (IIRC), pawn takes H6 is another option, and I think the only one.

@GMIgorSmirnov Rg1 to g2 preventing black queen from checking white king . Doesn’t matter where black queen moves and she’s the only piece who CAN move, white queens mates at h7 taking pawn.

Can you solve this tricky puzzle in 60 seconds? White mates in 2 🤔🤔

@GMIgorSmirnov Yup! Got it!

Brilliant Move, But Why? 🤔🤔

@GMIgorSmirnov Haha! Got it. Logical thinking. I was watching one of the championship games (GM-GM) and was wondering why one of them made a blunder that the other one didn't see. Taking the rook would've been stalemate. That comes into play here too.

White Mates In 2! (Tricky)

@StrsssTeme @Vantalane @DJSnM Just listen to all of say "vasaviation"'s videos. You'll need the subtitles for a while, but after a while you'll start to catch when the subtitles don't match what was being said. In short: It takes a bit of practice.

@Vantalane @DJSnM Well, I’m glad pilots and ATC can understand everything that’s being said, because I sure can’t. ☹️🤷‍♂️

Some random pilot telling ATC they can't comply with a request to slow down.

@MathGuyTFL This is one of the "homework problems" where I'd say "2/5" and the teacher would say "0 pts, show your work", and then I can't. Someone else here suggested dividing top and bottom by x^2. I wouldn't have come up with that myself.

Find the limit.

@carpinter11dan @GMIgorSmirnov You overlooked (just like me) black's KC7. You'd still win the game.

@GMIgorSmirnov Looks like bg5+ and rook d8 is mate

Brilliant Move, But Why? 🤔

@Cookie43208485 @GMIgorSmirnov Because the assignment says Mate in two not in three, four or nine. Some puzzles ask you to mate while you have less material than the other guy. If you don't find the exact right moves the other guy can crush you. In this case white has the advantage and CAN finish in two moves

@RogerWolff2 @GMIgorSmirnov Warum ist der erste Zug zwingend Qh1 und nicht c8-b8
