Meet my 20 month old son and his pet snake:
He pulled the belt out of a pair of pants, threw it onto the floor, made a “ssssss” sound, pointed at the belt, said “snake”, and backed away slowly. As far as Chelsea and I know, it was the first time he played with one of our belts, and the first time he (or either of us) called something a snake in the house. I imagine that he transferred this from … » More …
Rubotherm IsoSORP instruments utilize a Magnetic Suspension Balance to provide highly accurate fluid density and sorption measurements. The system utilizes Archimedes’ principle to determine fluid density by suspending a sinker of known mass and volume in a fluid and measuring the weight with a precision balance. The applied force is transmitted to the balance by the magnetic suspension which decouples the testing fluid from the balance. The Rubotherm IsoSORP at Washington State University has recently been retrofitted for cryogenic temperatures and pressure up to 4000 psi. By placing the test cell in a vacuum chamber and thermally connecting it to a Cryomech cryocooler I have … » More …
