Ok, so repeating, and replicating an experiment is good. How many times is best to validate results?
a couple...
a few...
many, many, many...
If someone replicates your experiment, and gets DIFFERENT results, is that a good or bad thing?

It's a bad thing.
It could be either, totally depends on the situation.
If YOU do your own experiment over, is that repeating it, or replicating it?

replicating it
If a young scientist, invented a battery for an iPhone that would stay charged for 2 weeks, she would...
...want to keep it a secret, and sell his idea to Apple.
...want to make a few "chargers" and have 3 friends try it out.
...have many scientists read about it, and test it out.
...write up a report, but only show her closest friends.
For the young scientist with the new iPhone battery, it would be best if other scientists...
...tried to get the same results.
...did the EXACT same steps, to see if they got the same results.

Scientists always share their data with others, why?
To brag, how smart they are...
To get PAID!!!
To see what other scientists think...
