It never was.
And it sure isn't now.
Remember how science said ulcers were induced chiefly by stress or spicy food? It turns out, they are induced chiefly by bacteria. Whoops.
The history of science is littered with "no wait....that's wrong...THIS is right..." going through the rinse and repeat cycle endlessly.
And that's ok. Inquiry and challenge and "being a science heretic" is, in many ways, how mankind learns more and can fix more problems.
But science isn't math. Your checking account balance is the sum of deposits less sum of withdrawals. Always. Forever.
The problem arises when people try to equate science with math...usually they call it "settled science." And, to be sure, robust inquiry and disciplined application of the scientific method usually gives you clear and distinct results. Then, science is settled...until we get new data or better techniques, and then we get "wait a minute..". For example, there was a most excellent article posted on how "settled science" wasn't so settled, wherein:
seems that Earth has been misplaced. According to a new map of the Milky Way galaxy, the Solar System's position isn't where we thought it was. Not only is it closer to the galactic centre - and the supermassive hole therein, Sagittarius A* - it's orbiting at a faster clip.
It further noted other "errors" in SCIENCE:
A good recent example of this is the red giant star Betelgeuse, which turned out to be closer to Earth than previous measurements suggested. This means that it's neither as large nor as bright as we thought. Another is the object CK Vulpeculae, a star that exploded 350 years ago. It's actually much farther away, which means that the explosion was brighter and more energetic, and requires a new explanation, since previous analyses were performed under the assumption it was relatively low energy
The other problem arises when Certain Powers work overtime to suppress assiduous inquiry. Which, is what we have today as well. It's a bad double whammy.
Science isn’t math.
It never was.
And it sure isn’t now.
Ha!
Hilarious.
Go tell that to Mr 15....no 30....no 365 +++ Days to Flatten the Curve FRAUDci.
Geez.
