Newton Calculation Error

in the book "Principia Mathematica" contains a simple calculation error that was not discovered for 300 years. Errors occur in Proposition Eight, where Newton presents a formula for calculating the mass of the planet, involving angles formed by two specific lines.

<h2>Further explanation </h2>

<em>The mistakes made by scientists: </em>

<h3>Galileo's Tidal Theories </h3>

He was wrong from the start, starting his efforts to explain the tidal movements with a false premise - namely that it was caused by the rotation of the earth around the sun. This means the theory is incorrect because it is based on mistakes.

<h3>Darwin and the Theory of Heredity </h3>

One problem with Darwin's original theory concerns heredity. Many people have a misconception about how characteristics are passed down from parents to their children. The problem is that this notion of mixed genetics contradicts Darwin's own theory. If that is true, then the characteristics will not change from generation to generation through natural selection.

<h3>Triple helix from Linus Pauling </h3>

Despite getting the Nobel Prize, Pauling admitted there was an error in his discovery. The model is wrong for a very simple reason: This includes the triple helix. He also made a basic mistake in his calculations, and the nucleic acid molecule in his model was actually not acidic.

<h3>Edwin Hubble's Universe Calculations </h3>

According to Hubble, the universe is two billion years old. This statement is proven wrong. In the 1930s, a study said the earth was between three and five billion years old. Obviously, our planet cannot be older than the universe, so something's wrong with Hubble.

The actual distance of Regulus from Earth is 23.81 parsecs.

Given:

Parallax of Regulus, p = 0.042 arc seconds

Calculation:

When an observer changes their position, an apparent change in the object's position takes place. This change can be calculated using the angle ( or semi-angle) made by the observer and object i.e. the angle made between the two lines of observation from the object to the observer.

Thus from the relation of parallax of a celestial body we get:

S = 1/ tan p ≈ 1 / p

where S is the actual distance between the object and the observer

            p is the parallax angle observed

Here for Regulus, we get:

S = 1 / p

  = 1 / (0.042)                                     [ 1 parsecs = 1 arcseconds ]

  = 23.81 parsecs

We know that,

1 parsecs = 3.26 light-years = 206,000 AU

Converting the actual distance into light years we get:

23.81 parsecs = 23.81 × (3.26 light yrs) = 77.658 light-years

Therefore, the actual distance of Regulus from Earth is 23.81 parsecs which is 77.658 in light years.

Is the energy of a wave is calculated by squaring the frequency of the wave?
Misha Larkins [42]
Nope.
Energy is directly proportional to frequency. and when you calculate energy, you multiply frequency with a constant number called "Planck's Constant"

E = hf

Hope this helps!

Sometimes balance point may not be obtained on the potentiometer wire why​
scoundrel [369]
Solution
Let a cell of emf E be connected across the entire length L of a potentiometer wire . Now , if the balance point is obtained at a length l during measurement of an unknown voltage

.
The balance point is not on the potentiometer wire - this statement means that

. In that case ,
l > L
V > E
