Can you solve the alien pyramid riddle? - Henri Picciotto

video description

Rating: 4.5; Vote: 2
You and your team of scientists are trapped on Mars. Can you figure out how to survive on the desert planet? Today is the anniversary of the best-worst day of your life. The best part was discovering a subterranean city on Mars. The worst part was when you lost contact with Earth. You and the other 99 scientists have spent the year engineering your survival, but you re almost out of water and solutions. Can you figure out how the last civilization lived on this desert planet? Henri Picciotto shows how. Lumberklik: Hoping you fix the 10 and 100 in the examples but I love how knowing about Pascal's triangle helps find the solution. Each number going two levels down is the side numbers plus two times the center. Going down three levels you add the two sides plus THREE times each of the interior numbers.

If you pull it, wouldn't part of the surface will be flooded which includes where the other 98 scientists are staying? They can elevate themselves first but then how long before all the water goes back to the surface? Also, the underground cavern is below ground so wouldn't that get flooded as well? The water may also not be suitable to drink for humans. Because of the condition of Mars, wouldn't the water evaporate into the atmosphere? There could also be micro-organism that could have evolved throughout the eons when the water was tucked away near the core of the planet. There are 99 minds in the planet, why weren't they able to fix the communication satellite yet? The lever is so huge. Martians must be giants. Maybe pull the lever to open the sewage and then close it again, study the water, and then slowly open and close it while the scientists can observe how having those liquids back in the surface react and how they can benefit from it, and from the people of the planet as well, and possibly, preserve any remains from ancient Martians so that they can study their abandoned civilization. Just my thoughts.

I was able to solve this one perfectly.
One hidden facet of the riddle that the video didn't really touch on is that it involves a property of Pascal's Triangle. The number at the top of each pyramid (1) is equal to the sum of the two numbers in the row below it (1, 1. Or count two rows down and it's the left number, plus twice the middle number, plus the right number (1, 2, 1. Or go to the bottom row with four numbers, and it's the sum of the left and right numbers, plus three times each of the two numbers in the middle (1, 3, 3, 1. And I'd wager this pattern would go on indefinitely with sufficiently tall pyramids.

There's something I don't understand here.
At 0: 56, the glyphs show that Y-- - for lack of a better representation - equals 100, ten of the bushels of ten widgets. But above it, Y is show to stand for 2, and I is shown to stand for 1, so by this reasoning, the I-- on the great pyramid should be 50, not 100.
So where is my reasoning going wrong?

One time there was this mom I knew that was a huge Harry Potter fan welll she got pregnant and the first thing she does was try to make the kid into Harry Potter. When he was like 5 he could see good after a eye test so she kept putting egg whites in his eyes to make his vision bad so he had to ware glasses like Harry Potter.

Whoops! Looks like we listed some of the alien symbols incorrectly. The last two numbers in the pictogram in the first pyramid (seen at 00: 55) should read: I - - (not Y - -, and I - - - (not Y - - -. We re working to get this fixed!

I was stuck trying to figure out the system behind their numbers. First thought the amount of spokes or angles, gave up and then continued the video only to find it was completely unnecessary and a waste of time.

For the solution to the second riddle, the visual approach is literally just doing the algebra again just with a green and an orange dot instead of x and y. There is nothing easier or helpful about it.
reply

Is it just me or is the alien decimal number shown at the start wrong? I was wracking my brain figuring out how they represented 100 with 200 but the solution at the end contradicts the earlier information

Everyone needs more than their salary to be financiaIIy stable. The best thing to do with your money is to lnvest it rightly so it grows because money left for savings always end up used with no returns.

I solved it! Finally after riddle videos and more riddle videos. I dont care if this one is a little bit easier than the others but I can now proudly say I solved one of TedEd riddle video!
reply

I solved it!
The clue is in the very important detail that there are 100 people on mars!
You have to wait 100 days to confirm you have green eyes and then just ask to leave!

reply

people must be like: woahhh these riddles are really hard to solve!
reality:
its harder to make these riddles, since you have to think of how people can answer to them.

reply

Why is
- - = 100
When in the beginning, 100 has recieved the representation of 2, followed by 2 zeros?
Meaning:
(Representation of 2) - - = 100?

reply

Unlucky typo in the examples.
And we could write the algebra but instead we write the algebra with colors replacing the variables is a weird aproach.
