<p>[QUOTE=&quot;Jochen1, post: 3979310, member: 103829&quot;]Dear Friends!</p><p><br /></p><p>An amazing calculation. It is possible that some people already know this.</p><p><br /></p><p>Caesar was murdered on the Ides of March, 44 B.C. Let us assume for the sake of simplicity that his last breath before his death was 1 liter. The number of molecules at sea level is about 2.55 x 10 to the power of 22 per litre (Wikipedia).</p><p><br /></p><p>The air volume of the earth corresponds to the earth&#039;s surface x height of the air column above sea level: earth&#039;s surface = 510 million square kilometers (Wikipedia).</p><p><br /></p><p>Let&#039;s assume the height of the air column is 5km. Above that the air is so thin that it doesn&#039;t matter to us anymore. This brings us to a total air volume of 510 million square kilometres x 5km = 2.55 x 10 to the power of 9 cubic kilometres = 2.55 x 10 to the power of 21 litres. Caesar&#039;s breath of 1 liter makes up 1 part of it.</p><p><br /></p><p>Let us further assume that the molecules of Caesar&#039;s last breath were evenly distributed in this volume of air during the 2063 years after his death. If we breathe in 1 liter of air today, then 1 in 2.55 x 10 to the power of 21 parts are from Caesar&#039;s last breath. Converted to molecules: 2.55 x 10 to the power of 22 molecules / 2.55 x 10 to the power of 21 = 10 molecules.</p><p><br /></p><p>In other words: </p><p>Each of us inhales by every breath about 10 molecules of Caesar&#039;s last breath!</p><p><br /></p><p>Of course, the same applies to other people in history. I do not want to go into details!</p><p><br /></p><p>Best regards[/QUOTE]</p><p><br /></p>
