I hate you Aristotleeeee...

"The trouble with the world is not that people know too little; it's that they know so many things that just aren't so"
Mark Twain
Hello guys and welcome back to my blog
Today we are going to talk about misconceptions induced in our mind by  Aristotle
So gear up and off we go
1) 'Everything that moves, will eventually come to a stop. Rest is the “natural” state of all objects'
Like seriously...
Had he been alive for 2009 more years he would have suicided of guilt and tons of bruises on him for leading humanity towards the wrong way for 2009 years (Almost two millenniums wasted on wrong ideas)
Newton's first law of motion was that "Every body in the universe continues to be in its state of rest or motion unless acted upon by an external force"
Or in simple words
"If the external forces on a body are balanced , then the body will continue to have zero acceleration due to which it will continually have constant velocity (motion) or be at rest"
2) "Constant force produces Constant motion"
According to Newton second law force produces accelaration which is directly proportional to force and inversely proportional to mass
So in light of second law any net force produces accelaration whether it is constant or variable
Or (F=ma)
3) "Heavier masses fall faster than lighter            ones"
Aristotle you just had to die 1912 years later..
Some may argue that it's true when a feather and a ball are dropped
But wait, there is a twist to it
It implies only for same material objects on Earth while anything in vacuum as different materials have different air resistance.
Drop a feather and a huge iron ball in vacuum and see the difference
If you have any more Misconceptions
Pls post in the comments
Btw I hate you Aristotleeeee... You just had to die 2341 years later for me to beat you up....
Your Physics expert signing off
See ya next time

    Dude lets respect the scientist, despite our disagreement to his theory... Infact if Aristotle was correct, then some day Big Bang should have turned into Big Crunch :) .. May be over infinite time....

    Actually lot of scientists claim that the expansion of galaxies shall slow down eventually due to the mutual gravitational forces that they apply on each other. And if that was true (lets say our null hypothesis), then the momentum of expansion of Galaxies in Big Bangs must be receding. Astronomers measure it in Hubble Constant (How fast are galaxies expanding/flying past each other)... Current Hubble constant is 70 km/sec/megaparsec.

    In other words, if you take a megaparsec of space – a cube which is about 3.2 million light-years across. Slightly bigger than the distance to the Andromeda galaxy, which has nothing to do with Kessel runs.

    For every second that goes by, that cube gets about 70 km bigger. A galaxy that’s 3.2 million light-years away is now 70 km further, and now it’s 70 km even further.

    Well, this Hubble constant must reduce, if someday everything gonnu be steady... But on the contrary its increasing... So currently it seems that the Null hypothesis is false....


    However, the moment big bang happened the galaxies have speeded away.. We might be still in an age where hubble constant is increasing... gradually it may reverse (just acceleration changing to decelaration) and then the contraction may begin... This is the chance of Aristotle being correct

    Hey
    What's your name
    And btw I was just joking
    I acknowledge his contributions to Science as without him no one would ever try to prove him wrong
    And today's post will be posted about Feyyman's models and Hubbles law (V=HoD)
    Thanks

    People find meaning in names, let me remain anonymous fan of Physics...
    Sorry to have missed your wit...
    Looking forward for Feyyman's model?

    BDW, dude whats your thought on Big Crunch? Like will the Hubble constant decelerate ever? Any model supporting it...

    BDW, lets also search if there is any constant, that evaluates change in Hubble constant over time... It may prove a great source for The Big Crunch Theory

God Doesn't Play Dice

Hello Guys and welcome back to my blog !!! Today we are going to talk about a huge controversy on Science during 1920s...   Albert Einstein   is one of the greatest and certainly best known physicists. If you ask anyone to name a physicist the most common answer you will receive is “Einstein”. Einstein is also famous for his quotations. Among the many Einstein’s quotations one is particularly popular among the general public: “God does not play dice”. But what did Einstein mean by this? The quotation says, “Quantum theory yields much, but it hardly brings us close to the Old One’s secrets. I, in any case, am convinced He does not play dice with the universe.” It was addressed by Einstein to Max Born (one of the fathers of Quantum Mechanics) in a letter that he wrote to Born in 1926. The “Old one” and “He” Einstein refers to is God. The fame of this quotation stems from two sources: 1) Einstein’s disagreement with the fundamental concept of Quan...

Antimatter - The Long Lost Cousin of Matter

A beautiful quote by Paul Dirac Many of you physics lovers would have figured out what I am gonna talk about Yes, The contrary to matter - Antimattter So now let's have a brief insight about it Antimatter: Classical physics only allowed systems to have positive energy. But Dirac’s new theory of relativistic quantum mechanics allowed for a particle with negative energy solution, as a counterpart to the familiar positive-energy electron. After ruling out the possibility that this particle was simply the proton – which has a hugely greater mass – Dirac predicted the existence of a new particle with the same mass of the electron but with a charge that was positive rather than negative. It’s now understood that all particles have an equivalent antimatter particle with opposite charge and quantum spin – although some are their own antiparticle. However hardly any antimatter is seen in the observable universe, and why there should be vastly much more normal ma...
