Which one of Columbus's beliefs was later proved to be true?
He believed the world was round and yes, the world is round.
How did James maxwell discover that light wave is an electromagnetic wave?
He added an extra mathematical term to Ampere's law and discovered that with what are now called Maxwell's equations there is a free-space solutions in the form of waves. He found that the wave solutions travel at the speed of light, so he guessed that they were light. This was later proved to be correct. The equations also predicted the existence of radio waves and these were discovered 15 years later.
What accusation was given by President Bush as a reason for invading Iraq but later proved false?
It was suspected that Sadam Hussein had "weapons of mass destruction" that he was hiding from the UN inspectors.
What happend when Pierre Curie tested radium on his skin?
skin turned grayish, hurt, and he thought radium could be used in treating cancer. that was later proved after his death.

Mendeleev developed the first periodic table and Mosely later modernized it.
What is corpernicus theory?
Contrary to most people of the 14th Century, Copernicus believed that the Earth revolved around the sun. Galileo later proved Copernicus' theory to be correct.
What is the MMR scare?
When a man Dr John Wakefield made up false evidence that there was a link between the MMR vaccine and autism. Later, the evidence was found to be proved wrong and it has been definitely certified that there is nothing wrong with the MMR vaccine and is safe to use.
What was the thing that was blank on Mendeleev's periodic table?
The elements which were not discovered at that time were made blank. Mendeleev named them as eka-aluminium, eka-silicon etc. They were discovered later and were placed in the gaps.
Did dmitry mendeleev credited with developing the first periodic table?
yes, demetri did create the first periodic table but Henery Mosley updated it years later.
How did Mendeleev discover the patter that led to the periodic table?
Mendeleev arranged elements in order of atomic mass. He arranged elements in rows and columns that later helped in discovering modern periodic table.
When do you connect the points on a graph?
11 year later its proved
How did mendeleev show that his periodic table was correct?
He didn't just arrange the elements based on atomic mass. If the chemical properties weren't similar - he'd change the order of them. He left gaps for elements that he knew would later be discovered and was successful in predicting the chemical properties of Ga and Sc which were later discovered.
Why did Dmitri Mendeleev leave some squares in his table blank?
Mendeleev left some gaps in his table for the elements which were not discovered at that time.Those elements were later found as silicon,gallium,germanium which were then filled in the gaps
What describes Mendeleev and use of the term Eka aluminum?
mixture of aluminum and an unknown element later called Germanium.
Is Durham castle haunted?
No! That is a myth proved by many researchers and experts. It became a tourist attraction due to this belief but was later proved to be untrue
Who first thought of the periodic table?
Many people thought of the idea, but we have given credit to Dmitri Mendeleev in 1869. I think its because he took the idea further and inscribed detail into his table, even predicting future elements. However, Lothar Meyer has also produced a similar version at essentially the same time as Dmitri Mendeleev.Some precursors include:Johann DobereinerA.E.Beguyer de ChancourtoisJohn Newlands
