The world would be a different place without it.

Penicillin
The discovery of penicillin is attributed to Scottish scientist and Nobel laureate Alexander Fleming in 1928. He showed that, if Penicillium notatum was grown in the appropriate substrate, it would exude a substance with antibiotic properties, which he dubbed penicillin. This serendipitous observation began the modern era of antibiotic discovery. The development of penicillin for use as a medicine is attributed to the Australian Nobel laureate Howard Walter Florey together with the German Nobel laureate Ernst Chain and the English biochemist Norman Heatley.

What other great inventions can we think of that has made it a better world to live in?
What about inventions that we could have done without? Any come to mind?

The polio vaccine was a truly wonderful thing, saved so many people
Video games we could have done without. Kids set and play them instead of playing outside or doing homework.

I love the automobile so I guess the engine would be on my list. I can do without ear plugs outside.

Two great inventions! Yes Polio vaccine definitly changed things for us all.
And the engine was a huge invention!

I have read alot of stories that take place during the mid 1800s during the industrial revolution. So many things came out of that. To make life easier and quicker. But alot of bad things came with it.

The phone was another great invention but at the same time.....it sometimes gets on my last nerve that no one can go out their front door to check their mail without bringing a darn phone with them! lol

Some practical inventions that i love are things like tin foil and saran wrap and sandwhich bags! lol...makes life alot easier. I also thing the microwave was an awesome invention!

Airplanes! They made the world so much smaller and easier to get around. After a very hot summer in Europe, air conditioning. We could do without fast food chains. Every where you go in the world these days there is a McDonalds, a Burger King etc. No wonder we are all having weight problems!
