More than 100 years ago Thermos used to be called a Dewar flask or Dewar bottle after its inventor  Scottish physicist and chemist Sir James Dewar. He invented it in 1892, but in 1904 lost a court case in claiming the rights to the invention to German company, Thermos GmbH, who started commertial production of vacuum flasks by the brand name "Thermos".

Numbers nerd. Guilty. I have always completely geeked out when working in Excel and creating spreadsheets that provide the information I need quickly and easily. I hate wasting my time in activities that do not add value and focus my efforts on being efficient as possible. My desire is to help others do the same! The files I create are tailored to the spreadsheet novice and do all the calculating for you. They are also always formatting to print out just right in case you need a hard copy.
