Marie Curie’s Research Papers Are Still Radioactive 100+ Years Later

When researching a famous historical figure, access to their work and materials usually proves to be one of the biggest obstacles. But things are much more difficult for those writing about the life of Marie Curie, the scientist who, along her with husband Pierre, discovered polonium and radium and birthed the idea of particle physics. Her notebooks, her clothing, her furniture, pretty much everything surviving from her Parisian suburban house, is radioactive, and will be for 1,500 years or more.

Cedar Point's Giant New Coaster Will Shatter Ten World Records Next Year

This will be a B&M Dive Machine coaster that will stand 223 feet tall. You'll rise up at a 47º angle on the lift hill and begin a slow turn before leaning over the 90º vertical first drop where the train comes to a stop on the edge of the drop for a moment to give you time to reflect.
Then you'll plunge 214 feet straight down, rise up into a huge Immelmann at 75mph and approach a second vertical drop that will rise up into a dive loop, a 270º roll inversion, hit an airtime hill and head for the brakes. The train itself will be a little different from other Dive Machines. It will feature 3 rows, each holding 8 riders across, but the restraints that will be used here will be the same soft-vest restraints used on Gatekeeper and other B&M Wing Coasters.
