Twins, good for minor characters in creepy horror films and known for the special bond that they’re supposed share. But what exactly is the difference between identical and non-identical twins I hear you say. Well, let’s get down to the science.
Your fingerprints are unique. They are yours, and yours alone. They can open doors, unlock your phone, let you into a country, or even just into a theme park. They are your personal identifier. Although there are many uses for fingerprints, perhaps the one which has most captured the public’s imagination is their use in forensic science. After all, how many criminals in stories wouldn’t have been caught without a careless fingerprint left at the scene. Because of this, it is quite fitting that this is also one of its first recorded uses.
If you can keep your hypothesis, when all about you
Are scrapping theirs and saying you should too,
If you can trust your calculations when all PIs doubt you,
But make allowance for poor maths skills too;
If you can incubate, and not be tired by waiting,
Or review papers, and see though bare faced lies,
Or do westerns, and don’t give way to hating,
And not be too upset about your cell cultures demise:
