Recently the most perfect spheres in the world were created as an answer to the "kilogram problem." Made to replace a chunk of platinum and iridium that has defined how much a kilogram weighs for 120 years (the weight of the metal has been changing ever so slowly ) the spheres are about the size of a melon and almost perfectly round. They are likely the most perfectly spherical objects on the planet.
"If you were to blow up our spheres to the size of the Earth, you would see a small ripple in the smoothness of about 12 to 15 mm, and a variation of only 3 to 5 metres in the roundness"
With this in mind we present you a collection of a few of the more interesting spheres found around the world.
Sweden Solar System: The world's largest model of our planetary system centered around the largest spherical building in the world.
The Mapparium: An three story inside-out glass globe built in 1935.
The Sudbury Neutrino Observatory: A gigantic spherical neutrino detector built into the largest man made underground cavity in the world.
Costa Rican Stone Spheres: Mysterious spherical rock formations from an earlier era.
Paris Sewer Museum: Giant wooden balls helped keep the Parisian sewers clean.
The Republic of Kugelmugel: A spherical "micro-nation" in the heart of Vienna.
A key challenge in building colonies on the moon is that it’s incredibly expensive to transport construction materials to space from Earth. That’s why researchers are exploring how moon bases could be mostly constructed from raw materials already there. A team of scientists working with the European Space Agency (ESA) are exploring how urine could […]
The new Mars rover Perseverance, set to launch in July for a February 2021 landing, will be outfitted with its own small helicopter. NASA engineers at Kennedy Space Station recently put the chopper through its paces, marking the last time they’ll spin it up before landing on the red planet. From Kennedy Space Center: The […]
American drug maker Johnson & Johnson said Monday it plans to begin the human testing phase of its experimental coronavirus vaccine by September 2020, with plans to make it available for emergency use in early 2021.
These toys and games can keep the kids busy while you’re all trapped inside. As rough as all this time cooped up inside the house is on us adults, it’s even worse for kids. All that borderline maniacal energy along with an unquenchable thirst for stimulation and attention make home sequestration like a life sentence […]
Python is everywhere. Just look under the hood of virtually every major tech player of the 21st century and you’re likely to find a whole lot of Python-based coding language staring back at you. Case in point: Netflix. You may not know it, but from its security protocols to its much-hyped recommendations, it turns out […]
There are definite benefits to the whole work from home thing. The commute is a breeze. The dress code is supremely casual. And your boss has to work a lot harder to actually find you. Despite the joys, there are still some clear downsides to the whole home office thing as well. Job focus can […]
