Signal boosting in case anyone needed to know this. 

This is informative as heck. Show this to everyone!

This is actually some great info! Why can’t they teach this kind of thing in school??

Wow, I’ve taken health and sex ed three times during my educational process and never learned any of this. Thanks.

Definitely some important information here!

this is supa awesome.  i do think it should be noted that side effects of EC *really* vary.  when I took EC I didn’t have any symptoms whatsoever.  

The more you know~

*High five.* This is amazing. We also did a video about EC if you’re interested, although, TBH, the above pretty much covers it. 


What movies made you feel especially like this? A lot of people are saying Lucy, but remember when NDT was pretty upset about Gravity? 

Explore! On Earth The Crusades

Okay, not everyone likes to read. This is especially true for many when it comes to reading about history. All those people and places, it is hard to keep up and not get super confused! So, we decided to try and ease the pain. 

Explore! On Earth The Crusades is a geospatial learning experience. It’s also a companion piece to the article pictured above. You can read the article here first and then dive in here further. All you need is Google Earth, a free program you can download here. Once it’s installed on your device, open up any of the files below and navigate through history on a 3D map (because a thousand 2D maps is overrated). Just click through the folders in order (or not, that’s up to you) or follow our numbering system and feel the knowledge sink into your think meat. 

Enjoy, you avid explorer!

Burning History and the Ashing of Science is the theme of our 9th issue! Why are people so set on defacing and destroying history? What events have occurred up until the present day that made future generations omit the past, both willingly and unwillingly. The story of Diego de Landa and the burning of Mayan books, the burning of Alexandria, the defacing of stone portraits, the omission of defeats in early city-state polities, Galileo and his persecution during the Renaissance, and religion’s role in retarding scientific advancement.

The first ever picture of the Mandelbrot set, from this 1978 paper by Robert Brooks and J. Peter Matelski.

For comparison, here’s a more modern representation of this fractal wonder:

Fold a piece of paper in half 103 times, and its wider than the observable universe.

this is due to exponential growth; the increase in previous thickness is doubled each time you fold the piece of paper again. physically you could probably only fold a piece of paper about 7 - 8 times on your own.

Given a paper large enough—and enough energy—you can fold it as many times as you want. If you fold it 103 times, the thickness of your paper will be larger than the observable Universe; 93 billion light-years distance.

How can a 0.0039-inch-thick paper get to be as thick as the Universe?

The answer is simple: Exponential growth. The average paper thickness in 1/10th of a millimeter (0.0039 inches.) If you perfectly fold the paper in half, you will double its thickness.

Folding the paper in half a third time will get you about the thickness of a nail.

Seven folds will be about the thickness of a notebook of 128 pages.

10 folds and the paper will be about the width of a hand.

23 folds will get you to one kilometer—3,280 feet.

30 folds will get you to space. Your paper will be now 100 kilometers high.

Keep folding it. 42 folds will get you to the Moon. With 51 you will burn in the Sun.

Now fast forward to 81 folds and your paper will be 127,786 light-years, almost as thick as the Andromeda Galaxy, estimated at 141,000 light-years across.

90 folds will make your paper 130.8 million light-years across, bigger than the Virgo Supercluster, estimated at 110 million light-years. The Virgo Supercluster contains the Local Galactic Group—with Andromeda and our own Milky Way—and about 100 other galaxy groups.

And finally, at 103 folds, you will get outside of the observable Universe, which is estimated at 93 billion light-years in diameters.

5 fun facts about fireflies (aka your favorite summer bug):

Fireflies mate for a full evening and spend the whole night together. Awwww.

The lights you see from fireflies are courtship signals that males are sending to females.

But firefly romance is risky business. “Femme fatale” fireflies seduce males, and then suck their blood to get chemicals for their own survival.

Around 150 million years ago, the very first fireflies flew during the daytime and didn’t light up. Today, there are still some firefly species where only the females light up.

The chemical that makes fireflies light up first evolved as a warning sign to ward off predators — and it tastes terrible. Don’t eat the fireflies, folks.

A Russian tank manufacturer has unveiled a new tram design that it plans to start mass-producing in 2015. These beautiful pieces of engineering will hold 190 to 270 passengers and will be able to traverse on even the older, worn out Russian tram tracks.
