Two SCIENTIST

  Hi I am Joy.I am sorry that i have not written for sooooooooooooooo long.Today I am going to tell you about two famous scientists.Marry Curie and Louis Pasteur.

Louis Pasture-Once luis pasture was experimenting with a kind of bacteria in his lab.For a snack he had kept some bread near it.He went out to get something.When he came back, he saw something had destroyed a part of the bacteria that he was experimenting with.He started thinking about what caused the bacteria to go away.Then he saw a fungus growing on his bread and immediately started to test if that was the reason the bacteria vanished.WOW! That was it Luis Pasture found a bacteria that kills the bad bacteria.And that my friends is now known as Penicillin. It was a very useful medicine in the olden times. It was also used when someone in war had gotten wounded and a bacteria started growing in the wound.

Liked the story? Here's one more.

Pasteurisation.Sounds familiar?

Well Luis Pasture found out that from the while the milk is delivered to our house the milk is already spoilt.So he found a method called pasteurisation.In that method the bacterias that are in the milk are given shock of sudden change of temperature. in the milk factories, they take all the milk and give it heat and suddenly make it cold. This causes the bacterias to die which spoil the milk. This method is followed even now.

EW!!!!!

Did you know that after pasteurizing it, the bacterias are dead but still in the milk! That means that we DRINK the bacterias!

Dont worry!

Even though there are bacterias in the milk they can't do anything to us and after a while, we excrete it!

Marie Curie-Once Merry Curie had kept few photo philms on her table.She had also kept some radioactive material on the same table.After a while, she saw that the photo film had some shadows on it.Then she started trying to figure out what caused this to happen?Then she got to know that these radioactive material emits rays that you can see through things.

That was the first X-ray.But sadly Merry Curie died because she was exposed to too much radioactive waves.Thanks for reading so much information but for now, bye!
