HOW DID I NOT KNOW THIS?!

Why do I learn more about math from Tumblr than my 12+ years of formal education????????

No math teacher ever taught me this trick. Got damn.

This is great and all if you know how to subtract things from 100

this is how I learned to stop doing it, people should reblog this. 

this is actually important

Hey look self harm advice that acknowledges that there’s more than two reasons that people do it

applauds

Reblogging this because my followers might be helped from this

This saved me.

I am forever going to reblog this post. Even if it isn’t really quality. I know from personal things that this NEEDS to be spread around Tumblr. If you don’t reblog this at least once I can guarantee I will judge you. Rebloging this could help someone out.

“Consider that you can see less than 1% of the electromagnetic spectrum and hear less than 1% of the acoustic spectrum. As you read this, you are traveling at 220 km/sec across the galaxy. 90% of the cells in your body carry their own microbial DNA and are not “you.” The atoms in your body are 99.9999999999999999% empty space and none of them are the ones you were born with, but they all originated in the belly of a star. Human beings have 46 chromosomes, 2 less than the common potato.

The existence of the rainbow depends on the conical photoreceptors in your eyes; to animals without cones, the rainbow does not exist. So you don’t just look at a rainbow, you create it. This is pretty amazing, especially considering that all the beautiful colors you see represent less than 1% of the electromagnetic spectrum.”

also, duct tape on your arms, a few layers, but not too tight. basically it’ll stop a zombie taking a chunk out of your arm if you’re reloading or your blade gets jammed in a zombie

wearing a wetsuit underneath your clothing would also be useful. remember; they were human once, humans have blunt teeth! you try biting through duct tape AND a wet suit

never duct tape joints, your movements will be limited, and you want to be fast and danger (gotta go fast)

don’t hole up in small houses either that’s a recipe for disaster, you want somewhere with a secure upstairs, and a way down from the upstairs that is zombie free or can easily be cleared of zombies (avoid fire exits with steps leading up to them though, unless they have gates at the bottom)

sound = attraction, so if you do have guns, use them only in emergencies or for the sake of popping one head you’ll be greeted with many many more

raid your local medical shops, and get there first, nobody is going to stop and share it out equally while they’re panicking. don’t hit out at somebody unless they hit out at you, though, you already have unintelligent corpses pitted against you, you don’t want sentient humans on your case as well (zombies don’t do the revenge thing, humans do!)

try not to piss people off, because as stated before, yes, humans like revenge

don’t try and be clever and use yourself as live bait; yes playing the hero is glorious in movies, but it doesn’t work so glamorously in real life

large numbers isn’t a good idea. you want small groups, even if you just branch out from being in a larger group, because if there’s a lot of you you are a bigger target, but don’t then go off and decide to be in groups that are too small in case you get surrounded (in which case, the duct tape and wet suits will come in handy)

food shouldn’t be that hard to come by, most people would have attempted to flee the area straight from their houses and packed what they had, raiding local shops could still be worth it. but remember, know your way in, your way out, and double check there’s nothing in the shop ready to sneak up behind you while you’re reaching up for that tin of beans

half balaclava masks or something similar to cover your lower face while fighting zombies could also be useful, you don;t want to accidentally ingest flying zombie fluids and end up one of them, that’d be a nasty surprise for your group to wake up to (since going solo possibly isn’t a good idea)

and always, ALWAYS, have a way to start a fire on you

zombies burn

He actually tells you not to set them on fire because why the fuck would they stop moving because they’re on fire? Have fun being eaten alive by a flaming zombie you dumb fuck.

actually that doesn’t make sense, heat is a very powerful neutralizing agent for neurons, while a zombie can still move while “dead” he still needs to tell his body what to do.

have you ever burnt your arm? how its numb for a bit before it really starts to burn, the worst of the pain comes later after the nerves have been reattached. A zombie on fire would quickly dismantle and fall to the ground assuming his entire body was on fire, in addition a zombie with his head on fire would quickly cause severe brain damage rendering the zombie inert.

Remember, zombies may be undead but they still need their brains, brains > all.

But, just to be on the safe side…avoid going all Firestarter unless you have to. Because even if the zombie does drop like a sack, it’d suck if it fell next to car abandoned at a gas station mid fill-up…or some fine (and flammable) drapery at a house you’re raiding.

Teen’s invention could charge your phone in 20 seconds

(Photo: Intel)

Waiting hours for a cellphone to charge may become a thing of the past, thanks to an 18-year-old high-school student’s invention. She won a $50,000 prize Friday at an international science fair for creating an energy storage device that can be fully juiced in 20 to 30 seconds.

Read the complete story.

Everybody, remember this face.
Remember this name.
If this becomes a commonly used & highly lauded discovery, at some point a White guy is going to take credit, even if he has to word it like “Improved upon a previous…”
No no no
Remember this brown girl.

What Would Happen if Oxygen Were to Disappear for Five Seconds?

A few things:

  • Everyone at the beach would get sunburns. Ozone is molecular oxygen and blocks the majority of UV light. Without it, we are toast.
  • The daytime sky would get darker. With fewer particles in the atmosphere to scatter blue light, the sky would get a bit less blue and a bit more black.
  • Every internal combustion engine would stall. This means that every airplane taking off from a runway would likely crash to the ground, while planes in flight could glide for some time.
  • All pieces of untreated metal would instantly spot-weld to one another. This is one of the more interesting side effects. The reason metals don’t weld on contact is they are coated in a layer of oxidation. In vacuum conditions, metal welds without any intermediate liquid phase (Cold welding).
  • Everyone’s inner ear would explode. As mentioned, we would lose about 21 percent of the air pressure in an instant, equivalent to being teleported to the top of the high Andes (elevation, about 2,000 meters).
  • Every building made out of concrete would turn to dust. Oxygen is an important binder in concrete structures (really, the CO2 is), and without it, the compounds do not hold their rigidity.
  • Every living cell would explode in a haze of hydrogen gas. Water is one third oxygen; without it, the hydrogen turns into gaseous state and expands in volume.
  • The oceans would evaporate and bleed into space. As oxygen disappears from the oceans’ water, the hydrogen component becomes an unbound free gas. Hydrogen gas, being the lightest, will rise to the upper troposphere and slowly bleed into space through Atmospheric escape.
  • Everything above ground would immediately go into free fall. As oxygen makes up about 45 percent of the Earth’s crust and mantle, there is suddenly a lot less “stuff” beneath your feet to hold everything up.

To sum, it wouldn’t be pretty.
