The Invention of the first pressure cooker.

First Pressure cooker.
There is a story that when French scientists and inventor Denis papin (1647-1712) first demonstrated his wonderfully named "digester" to London's Royal society in 1679 , the device exploded. So another invention swiftly came into being : Papin's safety valve ,which went on to have other applications .    
By 1682 , a refined version of the steam digester probed excellent at cooking food and making nutrious bones soft and tasty. After a demonstration dinner at royal society in that year, one guest, leading horticulturalist Jhon Evelyn, noted in his dairy that good served up from the digested was among "the most delicious that I  have ever seen or tasted". 

papin went on to experiment with similar principles in various important early steam-engine prototypes that he developed. Mean while his digested also informed the history of the autoclave (whose uses include sterilizing medical instruments)  and became the modern pressure cooker, which still works very much to his template.

In this scale lower numbers indicates higher brightness.  Sun Absolute magnitude is -4.83 Sirius Absolute magnitude -1.46 This nearest brightest thing to earth is R136A1 . What is it? R136A1 this is 265 times brighter than the sun . R136A1 Brightness is -12.6. This is more bigger than sun. Suppose if this would be in our sun's place then we could become blind by its brightness in fraction of seconds.  According to scientists the nearest brightest thing is R136A1.               ...
