The Evolution Of Potty Training Tech

At some point between the terrible twos and terrifying threes, most of us embarked on a pilgrimage to the great ceramic bowl in the sky. It was a long journey, which left in its wake frustrated parents, soiled sheets, and tiny mounds of ill-timed poop. But over time, with practice and patience, we collectively conquered the art of potty usage.


Why Military Tech (Sometimes) Doesn't Evolve

Consider the SR-71 Blackbird. It was meant to be used as a high altitude, high velocity recon aircraft. It was, and still is, one of the USAir Force’s greatest accomplishments, technologically speaking.


Wearing The Suit From Edge Of Tomorrow Would Basically Kill You

Those guns… would rip right off those armatures. Weapons, especially heavy weapons, cause a lot of recoil. I mean a lot of recoil. For comparison, I am going to consider the machine gun farthest back to be comparable to the US military’s 240-G.


Bloodletting And Bone Brushes: The White-Knuckle Days Of Early Dentistry

With all those gleaming, stainless-steel tools readied for painful prodding, few people look forward to visiting the dentist. But modern dentistry is a walk in the park compared with archaic methods of treating oral maladies: Be glad you’re not seeking treatment for mysterious “tooth worms” or using dentures filled with the syphilitic teeth of dead soldiers.


How Long Humans Can Live In Space -- And What Happens If We Stay Too Long

How long can humans live in space? We don’t know the answer to that. But every crew that resides on the International Space Station provides us information that we use to adjust our protocols and extends that period of time.


How Cotton Candy Was Popularised By... A Dentist

Cotton candy, in all of its colourful, puffy glory, is one of those timeless treats capable of evoking childhood with one disintegrating bite.


What Would Happen To The Internet If Mankind Disappeared?

Parts of it would die within a couple of days; if your access to it remained operational, some of it might remain partially usable for a year or two. All large complex systems require constant maintenance by huge staffs of intelligent people, and the internet is no exception. Like you’ve seen in future-dystopian sci-fi movies, infrastructure like this will slowly crumble.


The Stubborn 'Nail Houses' That Refuse To Get Demolished

In 1914, the government of New York City took ownership of a Manhattan apartment building belonging to one David Hess. The city used a legal power called eminent domain, allowing governments to seize private property for public use — in this case they wanted to expand the subway system. Hess fought them and lost, and when all was said and done, his building was torn down, and he was left with a triangle shaped piece of property. It was about the size of a large slice of pizza.


What Would Happen If The Sun Ceased To Exist For Just One Second?

If you mean simply “is not visible” then very little, we’d have a second of darkness, not unlike an eclipse, and then we’d be back to normal. If on the other hand, you mean “ceases to exist momentarily” then you’re talking about something else entirely.


11 Reasons Email Is The Worst

Email is one of those things that’s just a part of your life, period. Most of us know someone who has closed their Facebook account or refused to join in the first place in a little foot-stomping stand by their ego, and you might even know someone who is thrilled with themselves for not owning a smartphone.
