## Слайды и текст этой презентации

Слайд 1
Текст слайда:

Sir Isaac Newton

Слайд 2
Текст слайда:

Isaac Newton 1642-1727

Considered one of the greatest intellects that ever lived
Newton had a difficult childhood and was considered an odd boy.
He was sent to Cambridge in 1660 to earn a degree in law.

Слайд 3
Текст слайда:

During this time, a mostly Plato/Aristotle view of universe predominated.
Newton sought truth in science and math.
“Plato is my friend, Aristotle is my friend, but my best friend is truth.”

Слайд 4
Текст слайда:

Newton returns home

Graduated from Cambridge in 1665 with no distinction.
The plague closed university that same year.
Newton returned to his family’s farm for 18 months.

Слайд 5
Текст слайда:

1666 – Newton’s miracle year

Newton developed a theory of light (white light is composed of all colors).
He developed calculus.
Created his laws of motion.
And finally, created his universal theory of gravitation.

Слайд 6
Текст слайда:

Development of Calculus

He named it the “Method of Fluxions.”
Used it for finding areas, tangents, the lengths of curves and the maxima and minima of functions.

Слайд 7
Текст слайда:

Newton needed this to develop his laws of motion and law of gravitation.
The credit for calculus is now shared with Leibniz.

Слайд 8
Текст слайда:

Newton’s three laws of motion First Law

An object does what it’s already doing unless affected by an unbalanced force.
This is Galileo's concept of inertia.
Also called the “law of inertia”.
Friction is a force.

Слайд 9
Текст слайда:

This was more advanced than the Plutonian view of movement.

Слайд 10
Текст слайда:

Second Law of Motion

F = ma
F = net (unbalanced) force in Newtons
m = mass in kilograms
a = acceleration in m/sec2

Слайд 11
Текст слайда:

He probably used Galileo's experimental conclusions to develop this equation.
This equation can be developed from lab experiments.

Слайд 12
Текст слайда:

Newton’s Third Law of Motion

For every action, there is an equal and opposite reaction.
For every force, there is an equal and opposite force.

Слайд 13
Текст слайда:

Newton’s Universal Gravitation Theory

His “ah-ha!” experience started with a falling apple- does the moon also fall?
The same laws that apply to the Earth also apply to the heavens.

Слайд 14
Текст слайда:

Fg α m1m2/s2

F = force in Newtons
α read as “is proportional to”
m1 = mass of first object in Kg
m2 = mass of second object in Kg
s2 = distance between object’s center of gravity in meters

Слайд 15
Текст слайда:

Final form of gravitation equation

Fg = Gm1m2/s2
G = the gravitational constant (determined 100 years after Newton)
G = (6.67 x 10-11 N(m2/Kg2).

Слайд 16
Текст слайда:

Newton developed a mathematical “proof” based on his first 3 laws of motion.
This law also supported by Kepler’s calculations and orbit data.

Слайд 17
Текст слайда:

The universe is subject to “cause and effect” (responding to forces).
Less magic, and more reason.
All of nature can be explained by math and reason.
The universe is like a giant wind-up clock, set in motion at creation.

Слайд 18
Текст слайда:

Newton’s Social Life

Became a member of Royal Society of Science in 1672.
Reluctant to publish, because he was sensitive to criticism.
Was also very vindictive to enemies.

Слайд 19
Текст слайда:

Strengths of Newton’s Theory

Explains almost all observations.
Can accurately calculate outcomes (used to calculate everything from space shuttles to the design of skyscrapers).
For the most part, is derived by applying logic to everyday experience (applied common sense).

Слайд 20
Текст слайда:

Weaknesses of Newton’s Theory

The theory did not explain the cause of gravity – Why does mass attract mass?
Eventually, the absolute speed of light would create problems.
