Your Fingerprints Are Uniquely Yours Out of the World’s 7.2 Billion People

Anyone who knows anything about crime knows one of the first things detectives look for at a crime scene is fingerprints, those unique markers left by the ridges on everyone’s fingers.

These impressions have been used as personal signatures for thousands of years, going as far back as 300 B.C. in China, where letters would be sealed with clay and impressed with the authors fingerprint.

And in the late 1800s, a medical missionary in Japan named Henry Faulds was the first to publish research in a journal about the uniqueness, and potential for individualization, of these ridges.

It was around this time that fingerprints, with their loops, arches, and whorls, became an identifying factor in criminal cases. Sir Francis Galton, a jack-of-all-trades in many things scientific, calculated that the probability of two whole fingerprints matching was somewhere around one in 64 billion — making your fingerprints uniquely yours out of the 7.2 billion people around the world.

While it’s debatable how accurate that is (not everyone’s had their fingerprints taken, obviously) and how well forensic scientists can identify a person with them, the general consensus is they’ve been more accurate than not.

Slice Potatoes Before Baking For Uniquely Crispy Edges

Baked potatoes are great. Potato chips are great too. Fortunately, we live in a world where we can have the best of both worlds.

Instructables user rocket discovered that slicing your potato into thin segments before baking can yield crispy edges, and a soft potato center. Just slice thin segments of the potato about 3/4 of the way through, drizzle oil and salt on the top, and bake at 425° for about 50 minutes. By the time it’s done, you should have a unique, relatively-healthy treat. For added flavor, try stuffing some cheese or bacon into the slices during the baking process.
