Play hide and go seek

Einstein, Newton and Pascal are playing hide and go seek.

It's Einstein's turn to count so he covers his eyes and starts counting to ten.

Pascal runs off and hides.

Newton draws a one metre by one metre square on the ground in front of Einstein and stands in the middle of it.

Einstein reaches ten and uncovers his eyes.

He sees Newton immediately and exclaims, "Newton! I found you! You're it!"

Newton smiles and says, "you didn't find me, you found a Newton over a square metre. You found Pascal!"

Cool-stored blood transfusion

In 1916, blood that had been stored and cooled was used for the first time in a blood transfusion performed by the R.A.M.C. The procedure was very successful. Blood transfusions had been made previously, but this demonstrated the value of cooling to store blood. Until 1913, direct transfusion was the only technique practiced, despite being a difficult and time-consuming method, requiring trained personnel and was impractical for as a procedure in sudden emergencies. In the last two years of World War I, British surgeons benefitted from knowledge derived in the U.S. Use of blood collected and stored in advance of the need as casualties arrived facilitated transfusions as needed.[Image: blood transfusion was a mature procedure to treat casualties in World War II]
