So a friend of mine showed this to me: There are approximately two billion children (persons under 18) in the world. However, since Santa does not visit children of Muslim, Hindu, Jewish or Buddhist religions, this reduces the workload for Christmas night to 15% of the total, or 378 million (according to the Population Reference Bureau). At an average (census) rate of 3.5 children per house hold, that comes to 108 million homes, presuming that there is at least one good child in each. Santa has about 31 hours of Christmas to work with, thanks to the different time zones and the rotation of the earth, assuming he travels east to west (which seems logical). This works out to 967.7 visits per second. This is to say that for each Christian household with a good child, Santa has around 1/1000th of a second to park the sleigh, hop out, jump down the chimney, fill the stockings, distribute the remaining presents under the tree, eat whatever snacks have been left for him, get back up the chimney, jump into the sleigh and get on to the next house. Assuming that each of these 108 million stops is evenly distributed around the earth (which, of course, we know to be false, but will accept for the purpose of the calculations), we are now talking about 0.78 miles (1.3 km) per household; a total trip of 75.5 million miles (125.83 million km), not counting bathroom stops or breaks. This means Santa’s sleigh is moving at 650 miles per second (1083 km/s), 3000 times the speed of sound. For purposes of comparison, the fastest manmade vehicle, the Ulysses space probe, moves at poky 27.4 miles per second (45.7 km/s), and a conventional reindeer can run (at best) 15 miles per hour (25 km/h) - that is four thousands of a mile (4/1000) per second (6.9 m/s). The payload of the sleigh adds another interesting element. Assuming that each child gets nothing more than a medium size Lego set (two pounds, or 0.906 kg, that is), the sleigh is carrying over 500 thousand tons US (508,000 t metric), not counting Santa himself. On land, a conventional reindeer can pull no more than 300 pounds (136 kg). Even granting that the “flying” reindeer could pull ten times the normal amount, the job can’t be done with only eight or even nine of them - Santa would need 360,000 of them. This increases the payload, not counting the weight of the sleigh, another 54,000 tons (54,864 t metric), or roughly seven times the weight of the Queen Elizabeth (the ship, not the monarch). 600,000 tons (606,600 t metric) travelling at 650 miles per second (1083 km/s) creates enormous air resistance, and this would heat up the reindeer in the same fashion as a spacecraft re-entering the earth’s atmosphere. The lead pair of reindeer would absorb 14.3 quintillion Joules of energy per second each. In short, they would burst in flames almost instantaneously, exposing the reindeer behind them and creating deafening sonic booms in their wake. The entire reindeer team would be vaporized within 4.26 thousands of a second (0.00426 s), or right about the time Santa reached the fifth house on his trip. Not that it matters, however, since Santa, as a result of accelerating from dead stop to 650 miles per second (1083 km/s) in 0.001 seconds, would be subjected top acceleration forces of 17,500 g’s. A 250 pound (113 kg) Santa (which seems ludicrously slim) would be pinned to the back of the sleigh by 4,315,015 pounds of force (195,470 kg force, or 1.9547 MN), instantly crushing his bones and organs and reducing him to a quivering blob of pink goo. Therefore, if Santa did exist, he's dead now! That’s dedication.

Okay science side pls explain

why do my eyes water when i yawn but why don’t they water when i burp, cough, or sneeze? explain science side of tumblr?

[overreactivefangirl-blog]

Because you’re being exposed to something sad and stop having sad thoughts people be happy

Science side of tumblr

Why am i sad

And a lot of your focus is taken from the sense that is using it so your body can heighten other senses witht the energy left over at least thats my theory

Ok so I read this post where someone was making fun of themselves for turning down the volume on the TV so they could try to smell if something was burning, and you know we’ve all probably done something like that before, so I was thinking about it, and I doubt this is scientifically accurate, but it kind of makes sense if you think about how if one of the five senses is turned off then the others are heightened. Kind of like how if someone is blind they have really good hearing. Idk it’s just a thought. Like maybe that’s why we do things like that, so the other sense is heightened

Liquid in can. Can spray. Liquid congeals.

Science side of tumblr can you explain how silly string works?

[overreactivefangirl-blog]

Bcus its all of the ingredients perfectly mixed together and its delicious

@ science side of tumblr, why does raw cookie dough, brownie mix, cake mix, etc. taste so fucking good?

[overreactivefangirl-blog]

Depends on the size of the microwave, the handles, and the material of the handles.

Someone please tell me...

how many door handles would be able to fit in a microwave?

Because your brain is naturally repulsed by things that it is used to but with orher languages that was something not built in over time so ur brain isnt nearly as repulsed

Science side of Tumblr whose first language ISN’T English:

Help me understand why us, who don’t speak English as our first language can read any fanfiction and don’t feel weird but when we try to read (especially, but not only fanfiction) in our native language we want to take our eyes out.

Like, if I’m reading this super dirty fanfiction in English, with the most glorious sex scenes that you sort of wish the screenwriters put in the show, I don’t feel weird or anything.

I read something like “and then they kissed” in my native language and, not only it sounds lame, it just makes you cringe.

WHY IS THAT?

[overreactivefangirl-blog]

Your brain finds that it is orderly because the human mind is naturally attracted to order and peace

I find this strangely relaxing Why?

Because the light level is different for different areas in the specific place

The power went out in the middle of the night and left me with questions! I put on my headlamp to get around and caught all three cats with the light.

Axel’s eyes glowed the color I’m used to: a white/green-yellow.

Ghost’s eyes: unsettling red

Sheba’s eyes: the most brilliant blue I have EVER seen, I actually thought I had some electronic device on sitting on my bed with two blue LEDs before I realized it was her.

???? science side of tumblr why do my cats all have completely different color glowy eyes? what makes one eye glow a different color than another?

[overreactivefangirl-blog]

Its so adorable

Look, a bacon seed

[overreactivefangirl-blog]

Science side of tumblr, please explain. Why is it that when we read things we read them in different voices?
