There was a TIL not long ago illustrating how educated the writers of this show are. For anyone interested:

The writing staff held three Ph.D.s, seven master's degrees, and cumulatively had more than 50 years at Harvard University. Series writer Patric M. Verrone stated, "we were easily the most overeducated cartoon writers in history",

They still probably don’t understand Rick and Morty, though.

They also proved a thereom specifically for an episode of the show - http://theinfosphere.org/Futurama_theorem

I know this is a repost and people probably don't care, but those numbers weren't just chosen as arbitrarily large numbers whose difference was one; they could have made them much bigger if they wanted. This is special because it is exhibiting the prime factorization of 211 - 1, which is the smallest number that is one less than a prime power of two and not prime itself.

Primes of the form 2p - 1 are called Mersenne primes and they carry many nice properties. Said properties, for example, allow us to check for primality quicker than other numbers which is why the largest prime that we know of is always a Mersenne prime (and is expressed as above since writing it normally would require millions of digits).

Edit: haha this is basically the top comment on the other post, woops. I like math, so sue me.

Yes and no. The 91gbs speed number is based on their shadow network, which only connects a few select locations around the globe. It's not the 'internet' that we would normally think of, as it's primary purpose is only to move very large files from one NASA facility to another.

What if that file is the GTAV install?

sends file between coworkers

Drive read/write speeds would be the bottleneck

About as structurially sound as

But in all seriousness, If the balcony support beam was configured differently, I don't see why this wouldn't work as a real building. You would also need a frame of reference for how tall the structure is. Considering you can see the tops of other "Skyscraper" style buildings, I'm guessing pretty tall. The sides of the tower do not seems to be parallel, though, and would eventually meet if it was tall enough, which is my primary concern.

There would be hellacious structural loads, but nothing unsolvable with enough money and steel.

If someone wanted that built irl, it could be done.

would eventually meet if it was tall enough, which is my primary concern.

This is all I could find

It seems the sides are parallel.

Actually, people want this kind of stuff built, and it has been done:

This is from a previous post and user u/srappe:

Given a standard 53' trailer:

According to http://www.wbmcguire.com/links/Guides/TruckTrailerGuide.pdf, A 53' trailer has interior dimensions of 47'6" x 98.5" x 107.375" and a capacity of 3,489 cubic feet.

A 24 ct. box of Ramen Noodles has dimensions of 15" x 12" x 12" or a volume of 1.25 cubic feet.

u/Goldencaramel pointed out that I need to take in account for the pallets.

Pallets are 40" x 48" x 5" roughly. If the floor of the trailer has dimensions as listed above, you can fit 14 pallets lengthwise, and 2 width-wise. On the pallet itself, you can stack roughly 3 boxes of Ramen width-wise (40/12 = 3.33), 3 length-wise (48/15 = 3.2), and 4 height wise in order to be able to stack 2 pallets high in the truck (4*12 = 48). This gives the pallet, with the product a height of 53". Given the height of a trailer is 107.375", you can stack two pallets on top of each other with this packing method.

Therefore, you can fit 56 (14 x 2 x 2) pallets, each carrying 36 (3 x 3 x 4) boxes of Ramen into the truck

This means the maximum number of 24 ct. boxes of Ramen you can fit in a 53' trailer with pallets is 2016 (56 x 36)

These boxes sell at ~$12 at my local BJ's which means that the trailer would have a consumer value of about $24,192 (2016 * $12)

Now according to several people, you wouldn't stack pallets containing a product so fragile on top of one another. Also, according to a fellow freight broker, you can only fit 26 pallets in a trailer.

Re-do the math for a more "real-world" cost estimate and you come out to:

2636$12 = $11,232

Apologies for the repost

No, it's not a repost. The one I linked to was just asking how many Ramens can a semi truck hold. Your post is different just same answer.

Oh! Cool

there are 8 integers between 2 and 9 inclusive

probability of getting any particular combination of four random numbers in this range is (1/8)4 = 0.024%

edit: there's a lot of discussion about the random number generator in a ti-84. for your perusal, here is somebody who dug up the paper describing the method used (and verified it through emulation!), which is called a linear congruential random number generator. (actually this specific implementation appears to feed the output of one such generator into another, i think mostly to extend the period.) here is a direct link to that paper (implementation in figure 3). apparently the most common random number generators today are called 'mersenne twister' random number generators. the paper says the linear congruential random number generator used in the ti-83 has a period of 2.30484 * 1018 which is approximately 261 , whereas the most common mersenne twister implementation has a period of 219937 - 1. meaning that values will repeat each other every 261 times you use the random number generator on a ti-83. unless they're seeded with the same value at the factory, which many have suggested and would make me kinda sad.

A lot of these calculators have a seeded "random" number generator. It is pseudo-random and if you cleared the memory (reset the devoce) it would probably do it again

edit sudo -> pseudo

Solved! ✅

*pseudo-random

I don't have a definitive answer and it is late here, so sorry if that trails off.

Given the Amazon description, I'd say you need to place this somewhere between an Arduino and a Raspberry Pi, with the first not being able to run Doom and the second being able to do run it. Given that this came out in 2008, I'd say it is closer to an Arduino.

But there is actually a short story showing what it looks like from inside. That doesn't go into details of the used chip, but we can see there that a button cell is used to power that thing, something that isn't exactly used to power "powerful" stuff. The bigger ones hold up to 620mAh, which is nice, but have a maximum discharge current of ~0.2mA...which is...well, not a lot at all. From what I gather, that is hardly enough to run a very small variant of the Arduino. Which means that whatever is in there is actually not a general purpose chip, but the logic directly baked into circuits.

Which makes it rather unsuitable for running anything besides the logic it was designed for, unfortunately.

Arduino

Arduino is an open source computer hardware and software company, project, and user community that designs and manufactures single-board microcontrollers and microcontroller kits for building digital devices and interactive objects that can sense and control objects in the physical world. The project's products are distributed as open-source hardware and software, which are licensed under the GNU Lesser General Public License (LGPL) or the GNU General Public License (GPL), permitting the manufacture of Arduino boards and software distribution by anyone. Arduino boards are available commercially in preassembled form, or as do-it-yourself kits.

Arduino board designs use a variety of microprocessors and controllers.

Raspberry Pi

The Raspberry Pi is a series of small single-board computers developed in the United Kingdom by the Raspberry Pi Foundation to promote the teaching of basic computer science in schools and in developing countries. The original model became far more popular than anticipated, selling outside of its target market for uses such as robotics. Peripherals (including keyboards, mice and cases) are not included with the Raspberry Pi. Some accessories however have been included in several official and unofficial bundles.

Button cell

A watch battery or button cell is a small single cell battery shaped as a squat cylinder typically 5 to 25 mm in diameter and 1 to 6 mm high—like a button on a garment, hence the name. A metal can forms the bottom body and positive terminal of the cell. The insulated top cap is the negative terminal.

Button cells are used to power small portable electronics devices such as wrist watches, pocket calculators, artificial cardiac pacemakers, implantable cardiac defibrillators, automobile keyless entry transmitters, and hearing aids.

I couldn't find the actual specifications of a Cube World Cube. However, I think that Tamagochis will have fairly similar processing power to the Cube. But... I couldn't find the exact specifications of a Tamagochi either. What I did find however, is that they use a 4-bit microprocessor. A quick Google search led me to a PDF outlining the specifications of an EM6607 4-bit microprocessor, and so I am going to assume that the microprocessor has the same specifications and processing power as a cube. Let's do the math:

I'll start with the processor. Doom requires a single core processor running at 66Mhz to run. The Cube's processor runs at 32,768Hz. 66,000/32,768=2.01416016, but we'll round it up to 3, so we need 3 cubes minimum to have a fast enough processor to run Doom.

Now let's do the storage. Doom requires 40MB of ROM to install it. Were just going to assume that we don't need to install an operating system or a launcher, but that doom will launch when the cubes are turned on. Each cube has 32KB (2Kx16) of ROM. This means we need 40,000/32=1250 cubes minimum just to store the game. Let's move on to RAM.

The game requires 8MB of RAM, and each cube has 384 Bytes of RAM. 8,000,000/384=20833.3, but we'll round it to 20834 cubes. This is the new minimum amount of cubes so we have enough RAM for the game.

So assuming the cubes use the microprocessor I found online, we need a minimum of 20,834 cubes to run Doom. Whilst I was looking it up, I saw the average price for one cube was about £20 (~$26). To buy that many cubes, it would cost 20,834x20=£41,668 or $55,043. Hope this answers you question well OP.

Edit: There are 66MHz is 66,000,000Hz, not 66,000Hz. It's not 3 cubes to have enough processing power, it's 2015. Thanks u/ray_dog for pointing it out for me.

Edit 2: I forgot to multiply by 20, and just did it by 2 when working out the cost, so it would actually cost £416,680/$550,430.

I think your math is a little off.

32,768Hz = 32.768kHz

Or .032768MHz

You will need 2014 of these little guys.

[REQUEST] My 2nd grader's unusually broad math problem.Hi Math Friends! My kiddo gets math homework each night, and it's usually normal 2nd grade stuff. One of the problems tonight seems unusually broad. While I think it's a mistake of the wording of the problem, I am curious what the actual answer is (well, I am curious to know if I figured it out)

The problem is in the picture. Thanks in advance!!

This one's quick enough to enumerate.

Starting with the fours, Mai could have a combination of:

4 + 4 + 4

4 + 4 + 2

4 + 4 + 1

4 + 2 + 2

4 + 2 + 1

4 + 1 + 1

Moving on, she could also have had:

2 + 2 + 1

2 + 1 + 1

Or, lastly,

1 + 1 + 1

And therefore you have 9 choices.

Or, in other terms, let d equal the number of darts thrown (assuming all hit the board), and let s equal the number of possible scores.

d * s = p will yield the result: Darts * scores = possibilities.

If d = 3 and s = 3, then p = 9.

You left off 2+2+2 (not sure if intentionally) but since it is the same as 4+1+1 it doesn't represent a different possible score. Interesting that there's 10 dart outcomes but only 9 score outcomes

Well, the problem did stipulate that all throws hit the board.

Public school math teacher here. This is not an awful problem. The idea is to get kids to do a bit of direct modeling (thus the little dart board), practice simple repeated addition (maybe as prep for multiplication, given the number choices), look for patterns (some cases lead to the same results), and practice meta-problem solving skills (like attention to detail and task focus). The direct modeling (drawing a bunch of little dart boards and trying different configurations of dots) is well within the abilities of a seven year old. Unfortunately, a lot of teachers will treat a problem like this as a throwaway -- give it a check or a 'good job' sticker and move on. It kind of deserves a bit of class discussion. Not a whole lesson, but give kids a chance to share their approaches -- kinda like what's happening in this thread!

According to this, the wind power of an average mature hurricane is 1.5 x 1012 W

This site gives an average of 100 W for a box fan. Let's assume an overall efficiency of 60% for the fan and motor so fans produce 60 W of usable air flow energy.

This gives up 2.5 x 1010 fans, or 25 billion fans. We'd need more if we used weak little desktop fans like the one pictured. Assuming of course that we can somehow magically get 100% of the fan energy to go directly towards getting rid of the hurricane.

Should we start a fan club?

That's a lot of fans.

Edit: It was really more like a chuckle.

Assuming the 25 trillion gallons of rainfall estimate is correct and a flow rate of 25 gallons per minute through a 3/4" hose at typical household pressure,

1 trillion minutes or 16.67 billion hours or 694 million days or 1.902 million years

In other words it would need to have been flowing since 100,000 years after the appearance of the first species in our genus, homo habilis.

Interesting addition:

According to the EPA's evaporation equation for pools, we could only achieve about 30,000 square feet of surface area before we reached equilibrium between the rate of water inflow and evaporation. This assumes 25 mph average winds, a 60 degree Fahrenheit surface temperature, and that my math and the equation are accurate for the system. The equation being accurate for such a system is extremely unlikely but it's still fun to speculate.

Not to mention the fact that it gets absorbed into the soil/rivers/streams.

It will also evaporate more rapidly as it's surface area grows, eventually hitting some kind of equilibrium

While /u/cnl219 has the theoretical lower bound correct, the real answer is never. A faucet of that size with that flow rate would never flood the area the size of the Houston metropolitan area due to natural hydrological processes and evaporation.

According to this, 21.8% of the world was vegetarian in 2010 (couldn't find something more recent).

That means the rest (78.2%) eat some kind of meat (let's assume that includes beef at least once a year).

That would be 78.2% of 7.5 billion; 5.865 billion beef eaters.

So if each of those eating beef means 3432 trees not saved per year, then we should be losing trees today at a rate of 20 trillion trees a year.

According to this the world has about 3 trillion trees total, losing about 10 million a year.

So I call lettuceshit on that one.

I'll help a little: according to http://www.thepaperlessproject.com/facts-about-paper-the-impact-of-consumption/ , 700lb (+-340kg) of paper are consumed per capita per year on average. According to http://www.sierraclub.org/sierra/2014-4-july-august/green-life/how-much-paper-does-one-tree-produce , between 1000 and 2000 pounds of paper are produced by 8 trees. This means that per person (according to the huge fkin range given by that webpage) it would save 3-6 trees (very rough estimate) to go paperless.

I'll calculate the cows bit, but I'm assuming there's no absolutely direct relationship, it's probably about methane expelled into the atmosphere...

EDIT: quietly proceeds to mute Reddit notifications...

There's a fundamental flaw in the paper side because the paper industry maintains their own tree farms. They plant more than they cut down and maintain commercial forests that are healthier than natural ones with higher rates of photosynthesis. Using less paper is actually detrimental to tree conservation.

Upvote for lettuceshit. And the explanation.

Edit: this is my most upvoted comment by far. How random. I love it.
