National Mole Day
National Mole Day is celebrated on October 23rd each year from 6:02 am to 6:02 pm, in observance of the "mole." For 2018, the Mole Day theme is "Moley Potter." The "mole" is a way of counting Avagadro's number, which is 6.02 x 10 to the 23rd power of anything (just as a dozen is a way of counting 12 of anything).
Mole Day owes its existence to a 19th century physics professor named Amedeo Avagadro. He discovered that the number of molecules in a "mole" is the same for all substances. Because of this, chemists are able to accurately measure quantities of chemicals.

Touch a Truck at annual event October 20
A favorite of Norman-area families for more than a decade, the Pioneer Library System Foundation and a variety of community partners will present Touch A Truck from 9 a.m. to noon Saturday, Oct. 20, at the Cleveland County Fairgrounds.
The 14th edition of the annual event features dozens of trucks, including public service vehicles, big rigs, construction machines and much more.
Attendees will have a chance to get an up-close look at the vehicles and learn a little more about how they serve the community from their operators.
The first hour of the event, from 9 to 10 a.m., is a “Quiet Hour” especially set for families with children who may have sensory sensitivity or just not like the noise created from dozens of horns honking.
Beginning at 10 a.m., the noise gets started as kids can try out the horns as they sit in the driver’s seat of their favorite trucks.
There is no official entry fee for the event, although donations will be taken at the entrances. Proceeds go to benefit the Children’s Services departments of the Pioneer Library System’s six Cleveland County libraries – Moore, Noble, Southwest Oklahoma City and Norman’s three libraries at West, Central and the recently opened Norman East library.
Sponsors for this year’s event are Absolute Data Shredding, dotprocessagents.com LLC, First Fidelity Bank, Norman Behavioral Health Group, Norman Pediatric Associates, Norman Regional Health System, OEC, State Farm Insurance Agent Julia Chew, Victor T. Wilson MD, FAAP, OG&E, Pamela Sharp at State Farm and Traci R. Sykes Foundation.
Past editions of Touch A Truck have drawn more than 3,000 visitors to the Fairgrounds, with library and vehicle enthusiasts of all ages getting a chance to get an up-close look at participating vehicles.
Among the vehicles on hand will be the Pioneer Library System’s Maker Mobile, which will give a look at its special features, which include a three-dimensional printer, laser cutter and some of the STEAM Kits available for use through the library system to promote science, technology, engineering, the arts and mathematics.
