TOP 10 Science Mistakes
No. 10 - Alchemy - the idea that cheap common lead could be turned into expensive beautiful GOLD!
No. 9 - Heavier Objects Fall Faster - I used to demonstrate this to my science classes with a balled of paper and a solid toy iron.
No. 8 - Phlogiston - You HAVE heard of phlogiston haven't you? NO IT IS NOT some new body cream!
I omitted #6 because it actually was NOT a science theory.
DNA was discovered in 1869, but for a long time, it was kind of the unappreciated assistant: doing all the work with none of the credit, always overshadowed by its flashier protein counterparts.
No. 3 - Germs in Surgery Laugh or cry (take your pick), but up until the late 19th century, doctors didn't really see the need to wash their hands before picking up a scalpel.
No. 2 - The Earth Is the Center of the Universe Chalk it up to humanity's collectively huge ego. Second-century astronomer Ptolemy's (blatantly wrong) Earth-centered model of the solar system didn't just stay in vogue for 20 or 30 years; it stuck around for a millennium and then some.
No. 1 The Circulatory System You don't have to be a doctor to know how important the heart is...but back in ancient Greece, you could be a doctor and STILL have no idea how important the heart is.
