What day is it?

Over breakfast one morning, a woman said to her husband, "I bet you don't know what day this is."

"Of course I do," he indignantly answered, getting up from the table and going out the door to the office.

At 10am, the doorbell rang. When the woman opened the door, she was handed a box containing a dozen long-stemmed red roses. At 1pm, a foil-wrapped, two-pound box of her favorite chocolates arrived. Later, a boutique delivered a designer dress.

The woman couldn't wait for her husband to come home. When he did, she exclaimed, "First the flowers, then the chocolates and then the dress! I've never had a more wonderful Groundhog Day in my life!"

Svedberg's colloidal sol patent

In 1909, Swedish chemist Theodor Svedberg filed to patent his method of producing colloidal sols or gels, simultaneously in Great Britain, Germany, Denmark and Switzerland. By 1926, he received the Nobel Prize in Chemistry for his work with disperse systems. In colloidal systems, extremely fine particles are dispersed in a continuous medium, in which they remain suspended indefinitely. In molecular-disperse systems, the particles are large molecules like proteins or haemoglobin. Svedberg invented an ultracentrifuge to investigate them. At 40,000 revolutions/min, the particles were redistributed towards the periphery of the motion. Analysis of photographs of the distribution yielded the molecular weight of the particles.«
