The 1K Perfect Sphere
Durring my semester in Physics I've had to use different forms of measurement, the kilogram in particular. After doing some research on what exactly was a kilogram, I have found out that use to be based off of a physical object. After some time, a problem was discovered with the object. The mass of the object would slightly change over time. It is still not clear why this happens, as a solution scientist have found a way to fix the problem and no longer be dependent on a physical object. To begin they have created a perfect sphere out of silicon that weights exactly 1 kilogram and has a monetary value of around one million euros. What scientist will do with this object is calculate the number of atoms in the object. 1K= Number of atoms that is in 12g of c-12. By knowing the number of atoms we will be able to define exactly what is a kilogram. Hopefully in the near future we will no longer rely on physical objects to define out weight in the world.
