Professor Dave FAILS math

#shorts
Professor Dave is displays the Dunning Kruger effect.

This has to be satire. There’s no way you created, reviewed, and posted this genuinely believing you are making a good point.

[nebuchadnezzar]

Other than calling it exponential (which is true if we accept a loose definition of the word) everything else he said was true. You're just being pedantic here and arguing more about semantics than mathematics.

[originalfowlboy]

This comment section is sad af. At least most of the top comments are from literate people.😅😅😂😂

Let's set m1 and m2 both equal to 1.

At r=1, the force would equal 1G
At r=2, the force would equal (1/4)G
At r=3, the force would equal (1/9)G
At r=4, the force would equal (1/16)G
At r=5, the force would equal (1/25)G

You see how the denominator (that's the bottom number of the fraction) gets exponentially bigger as the distance increases linearly? That means the force decays exponentially as the distance increases linearly. I'm sorry you don't understand what an exponential is, but what you yourself showed in your graph was an exponential decay of force. If it was linear, F would equal (1/r)*G. It does't. The only thing you've shown is that you don't know how to do basic algebra.

I know nothing about Professor Dave but if this video is the best you can find to critique him, man must be an infallible genius.

[bastard]

Tell me you failed high school without telling me you failed high school

[The_campfire-wm]

Its funny how people like you will find a trivial instance where he mispoke and ignore all the other really good points he makes, as well as ignoring his actual challenges

[dikchez]

He was using 'exponential' figuratively. You might be mildly acoustic.

[cortical]

The word 'quadratus' means squared, and anything raised to the power 2 is called its sqaure. Quadratic equations originated from geometric problems involving squares. Dave is, of course, 100% correct. 🧠🔥

[illuzion]

Hey, even quadratic equations increase or decrease exponentially, depending on what definition you're using. In normal english, saying something changes "exponentially" just means that the rate of change is itself changing and not constant. It doesn't always refer to an exponential equation.

[ILoveMaths]

He used the word 'exponentially' figuratively, not literally.

[bentarpenning]

POV: you daydreamed abt flat-earth theories during math class

[valkhorn]

Dave is right. When something gets exponentially smaller it gets smaller by a factor of one over X to an exponent. In this case this is what it does. Why are flerfs so bad at math?

[SnapdragonAtheist]

Lying about math to defend your belief that the earth is flat is crazy lol

[bigchungus]

"WRONG!" .. proceeds to show a graph that behaves exactly how professor dave described it would

[myalternativereality]

At least the uploader of this video believes in gravity, and provided a nice graph and equation as evidence. I mean, they could have been a dumb flat earther or wait! (Cue curb your enthusiasm music)

[ralphwalters]

If the force decreases exponentially, the denominator would be Euler's number raised to the power of the displacement, or 1/e^r. The force is decreasing by the square of the inverse displacement .

[Rimlick]

When a slam dunk consists of showing a graph with no units, I fear it may have been on the wrong net.

[TheLoobis]

I don't even know what i was looking at. Can you explain it?

[glennpearson]

Ridiculous argument in semantics. How large does a variable exponent need to be before we are allowed to use the term "exponential?"
