Things I learned lately - 19 Mar

• The UK will soon tax the makers of sugary soft drinks based on the amount of sugar in their beverages.
• The Nevada National Security Site (Proving Grounds) was the site of 100 above ground nuclear bomb tests and 828 underground nuclear bomb tests between 1951 and 1986.
• Ingvar Kamprad, the 89 year old founder of Ikea is worth €65.5 billion. But he still buys second-hand clothes. He tries to get a haircut when he's in a developing country too.
• In the mid to late 1800s, most immigrants to the US were from Ireland and Germany. Also, a lot of immigrants into northern states were from Canada.
• NASA is working on a supersonic passenger jet design that produces more of a sonic thump than a boom. This could revitalize supersonic travel. The first prototype will fly by 2020.
• Goodbye is an evolution of the contraction from the phrase 'God be with ye'.
• The saw blade they use to cut off plaster casts (for bone break injuries) doesn't rotate, it just vibrates. There's no risk to the skin.
